The present disclosure relates to methods and systems for data collection in industrial environments, as well as methods and systems for leveraging collected data for monitoring, remote control, autonomous action, and other activities in industrial environments.
Heavy industrial environments, such as environments for large scale manufacturing (such as manufacturing of aircraft, ships, trucks, automobiles, and large industrial machines), energy production environments (such as oil and gas plants, renewable energy environments, and others), energy extraction environments (such as mining, drilling, and the like), construction environments (such as for construction of large buildings), and others, involve highly complex machines, devices and systems and highly complex workflows, in which operators must account for a host of parameters, metrics, and the like in order to optimize design, development, deployment, and operation of different technologies in order to improve overall results. Historically, data has been collected in heavy industrial environments by human beings using dedicated data collectors, often recording batches of specific sensor data on media, such as tape or a hard drive, for later analysis. Batches of data have historically been returned to a central office for analysis, such as undertaking signal processing or other analysis on the data collected by various sensors, after which analysis can be used as a basis for diagnosing problems in an environment and/or suggesting ways to improve operations. This work has historically taken place on a time scale of weeks or months, and has been directed to limited data sets.
The emergence of the Internet of Things (IoT) has made it possible to connect continuously to, and among, a much wider range of devices. Most such devices are consumer devices, such as lights, thermostats, and the like. More complex industrial environments remain more difficult, as the range of available data is often limited, and the complexity of dealing with data from multiple sensors makes it much more difficult to produce “smart” solutions that are effective for the industrial sector. A need exists for improved methods and systems for data collection in industrial environments, as well as for improved methods and systems for using collected data to provide improved monitoring, control, intelligent diagnosis of problems and intelligent optimization of operations in various heavy industrial environments.
Industrial system in various environments have a number of challenges to utilizing data from a multiplicity of sensors. Many industrial systems have a wide range of computing resources and network capabilities at a location at a given time, for example as parts of the system are upgraded or replaced on varying time scales, as mobile equipment enters or leaves a location, and due to the capital costs and risks of upgrading equipment. Additionally, many industrial systems are positioned in challenging environments, where network connectivity can be variable, where a number of noise sources such as vibrational noise and electro-magnetic (EM) noise sources can be significant an in varied locations, and with portions of the system having high pressure, high noise, high temperature, and corrosive materials. Many industrial processes are subject to high variability in process operating parameters and non-linear responses to off-nominal operations. Accordingly, sensing requirements for industrial processes can vary with time, operating stages of a process, age and degradation of equipment, and operating conditions. Previously known industrial processes suffer from sensing configurations that are conservative, detecting many parameters that are not needed during most operations of the industrial system, or that accept risk in the process, and do not detect parameters that are only occasionally utilized in characterizing the system. Further, previously known industrial systems are not flexible to configuring sensed parameters rapidly and in real-time, and in managing system variance such as intermittent network availability. Industrial systems often use similar components across systems such as pumps, mixers, tanks, and fans. However, previously known industrial systems do not have a mechanism to leverage data from similar components that may be used in a different type of process, and/or that may be unavailable due to competitive concerns. Additionally, previously known industrial systems do not integrate data from offset systems into the sensor plan and execution in real time.

The system may enable selecting a portion of the second data that corresponds to the set of lines of resolution and the frequency range of the first data, and processing the selected portion of the second data with the first data sensing and processing system.
Methods and systems described herein for industrial machine sensor data streaming, collection, processing, and storage may be configured to operate and integrate with existing data collection, processing and storage systems and may include a method for automatically processing a portion of a stream of sensed data. The sensed data is received from a first set of sensors deployed to monitor aspects of an industrial machine associated with at least one moving part of the machine.

The set of sensed data is constrained to a frequency range. The stream of sensed data includes a range of frequencies that exceeds the frequency range of the set of sensed data, the processing comprising executing an algorithm on a portion of the stream of sensed data that is constrained to the frequency range of the set of sensed data, the algorithm configured to process the set of sensed data.

Detailed embodiments of the present disclosure are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the disclosure, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
Methods and systems described herein for industrial machine sensor data streaming, collection, processing, and storage may be configured to operate with existing data collection, processing, and storage systems while preserving access to existing format/frequency range/resolution compatible data. While the industrial machine sensor data streaming facilities described herein may collect a greater volume of data (e.g., longer duration of data collection) from sensors at a wider range of frequencies and with greater resolution than existing data collection systems, methods and systems may be employed to provide access to data from the stream of data that represents one or more ranges of frequency and/or one or more lines of resolution that are purposely compatible with existing systems. Further, a portion of the streamed data may be identified, extracted, stored, and/or forwarded to existing data processing systems to facilitate operation of existing data processing systems that substantively matches operation of existing data processing systems using existing collection-based data. In this way, a newly deployed system for sensing aspects of industrial machines, such as aspects of moving parts of industrial machines, may facilitate continued use of existing sensed data processing facilities, algorithms, models, pattern recognizers, user interfaces, and the like.
Through identification of existing frequency ranges, formats, and/or resolution, such as by accessing a data structure that defines these aspects of existing data, higher resolution streamed data may be configured to represent a specific frequency, frequency range, format, and/or resolution. This configured streamed data can be stored in a data structure that is compatible with existing sensed data structures so that existing processing systems and facilities can access and process the data substantially as if it were the existing data. One approach to adapting streamed data for compatibility with existing sensed data may include aligning the streamed data with existing data so that portions of the streamed data that align with the existing data can be extracted, stored, and made available for processing with existing data processing methods. Alternatively, data processing methods may be configured to process portions of the streamed data that correspond, such as through alignment, to the existing data, with methods that implement functions substantially similar to the methods used to process existing data, such as methods that process data that contain a particular frequency range or a particular resolution and the like.
Methods used to process existing data may be associated with certain characteristics of sensed data, such as certain frequency ranges, sources of data, and the like. As an example, methods for processing bearing sensing information for a moving part of an industrial machine may be capable of processing data from bearing sensors that fall into a particular frequency range. This method can thusly be at least partially identifiable by these characteristics of the data being processed. Therefore, given a set of conditions, such as moving device being sensed, industrial machine type, frequency of data being sensed, and the like, a data processing system may select an appropriate method. Also, given such a set of conditions, an industrial machine data sensing and processing facility may configure elements, such as data filters, routers, processors, and the like, to handle data meeting the conditions.
With reference to
Intelligent systems 118 may include cognitive systems 120, such as enabling a degree of cognitive behavior as a result of the coordination of processing elements, such as mesh, peer-to-peer, ring, serial, and other architectures, where one or more node elements is coordinated with other node elements to provide collective, coordinated behavior to assist in processing, communication, data collection, or the like. The MANET 20 depicted in
Intelligent systems may include machine learning systems 122, such as for learning on one or more data sets. The one or more data sets may include information collected using local data collection systems 102 or other information from input sources 116, such as to recognize states, objects, events, patterns, conditions, or the like that may, in turn, be used for processing by the host system 112 as inputs to components of the platform 100 and portions of the industrial IoT data collection, monitoring and control system 10, or the like. Learning may be human-supervised or fully-automated, such as using one or more input sources 116 to provide a data set, along with information about the item to be learned. Machine learning may use one or more models, rules, semantic understandings, workflows, or other structured or semi-structured understanding of the world, such as for automated optimization of control of a system or process based on feedback or feed forward to an operating model for the system or process. One such machine learning technique for semantic and contextual understandings, workflows, or other structured or semi-structured understandings is disclosed in U.S. Pat. No. 8,200,775 to Moore, issued 12 Jun. 2012, and hereby incorporated by reference as if fully set forth herein. Machine learning may be used to improve the foregoing, such as by adjusting one or more weights, structures, rules, or the like (such as changing a function within a model) based on feedback (such as regarding the success of a model in a given situation) or based on iteration (such as in a recursive process). Where sufficient understanding of the underlying structure or behavior of a system is not known, insufficient data is not available, or in other cases where preferred for various reasons, machine learning may also be undertaken in the absence of an underlying model; that is, input sources may be weighted, structured, or the like within a machine learning facility without regard to any a priori understanding of structure, and outcomes (such as those based on measures of success at accomplishing various desired objectives) can be serially fed to the machine learning system to allow it to learn how to achieve the targeted objectives. For example, the system may learn to recognize faults, to recognize patterns, to develop models or functions, to develop rules, to optimize performance, to minimize failure rates, to optimize profits, to optimize resource utilization, to optimize flow (such as flow of traffic), or to optimize many other parameters that may be relevant to successful outcomes (such as outcomes in a wide range of environments). Machine learning may use genetic programming techniques, such as promoting or demoting one or more input sources, structures, data types, objects, weights, nodes, links, or other factors based on feedback (such that successful elements emerge over a series of generations). For example, alternative available sensor inputs for a data collection system 102 may be arranged in alternative configurations and permutations, such that the system may, using generic programming techniques over a series of data collection events, determine what permutations provide successful outcomes based on various conditions (such as conditions of components of the platform 100, conditions of the network 110, conditions of a data collection system 102, conditions of an environment 104), or the like. In embodiments, local machine learning may turn on or off one or more sensors in a multi-sensor data collector 102 in permutations over time, while tracking success outcomes such as contributing to success in predicting a failure, contributing to a performance indicator (such as efficiency, effectiveness, return on investment, yield, or the like), contributing to optimization of one or more parameters, identification of a pattern (such as relating to a threat, a failure mode, a success mode, or the like) or the like. For example, a system may learn what sets of sensors should be turned on or off under given conditions to achieve the highest value utilization of a data collector 102. In embodiments, similar techniques may be used to handle optimization of transport of data in the platform 100 (such as in the network 110) by using generic programming or other machine learning techniques to learn to configure network elements (such as configuring network transport paths, configuring network coding types and architectures, configuring network security elements), and the like.
In embodiments, the local data collection system 102 may include a high-performance, multi-sensor data collector having a number of novel features for collection and processing of analog and other sensor data. In embodiments, a local data collection system 102 may be deployed to the industrial facilities depicted in
In embodiments, the main Mux board and/or the MUX option board then connects to the mother (e.g., with 4 simultaneous channels) and daughter (e.g., with 4 additional channels for 8 total channels) analog boards 1110 via cables where some of the signal conditioning (such as hardware integration) occurs. The signals then move from the analog boards 1110 to an anti-aliasing board (not shown) where some of the potential aliasing is removed. The rest of the aliasing removal is done on the delta sigma board 1112. The delta sigma board 1112 provides more aliasing protection along with other conditioning and digitizing of the signal. Next, the data moves to the Jennic™ board 1114 for more digitizing as well as communication to a computer via USB or Ethernet. In embodiments, the Jennic™ board 1114 may be replaced with a pic board 1118 for more advanced and efficient data collection as well as communication. Once the data moves to the computer software 1102, the computer software 1102 can manipulate the data to show trending, spectra, waveform, statistics, and analytics.
In embodiments, the system is meant to take in all types of data from volts to 4-20 mA signals. In embodiments, open formats of data storage and communication may be used. In some instances, certain portions of the system may be proprietary especially some of research and data associated with the analytics and reporting. In embodiments, smart band analysis is a way to break data down into easily analyzed parts that can be combined with other smart bands to make new more simplified yet sophisticated analytics. In embodiments, this unique information is taken and graphics are used to depict the conditions because picture depictions are more helpful to the user. In embodiments, complicated programs and user interfaces are simplified so that any user can manipulate the data like an expert.
In embodiments, the system in essence, works in a big loop. The system starts in software with a general user interface (“GUI”) 1124. In embodiments, rapid route creation may take advantage of hierarchical templates. In embodiments, a GUI is created so any general user can populate the information itself with simple templates. Once the templates are created the user can copy and paste whatever the user needs. In addition, users can develop their own templates for future ease of use and to institutionalize the knowledge. When the user has entered all of the user's information and connected all of the user's sensors, the user can then start the system acquiring data.
Embodiments of the methods and systems disclosed herein may include unique electrostatic protection for trigger and vibration inputs. In many critical industrial environments where large electrostatic forces, which can harm electrical equipment, may build up, for example rotating machinery or low-speed balancing using large belts, proper transducer and trigger input protection is required. In embodiments, a low-cost but efficient method is described for such protection without the need for external supplemental devices.
Typically, vibration data collectors are not designed to handle large input voltages due to the expense and the fact that, more often than not, it is not needed. A need exists for these data collectors to acquire many varied types of RPM data as technology improves and monitoring costs plummet. In embodiments, a method is using the already established OptoMOS™ technology which permits the switching up front of high voltage signals rather than using more conventional reed-relay approaches. Many historic concerns regarding non-linear zero crossing or other non-linear solid-state behaviors have been eliminated with regard to the passing through of weakly buffered analog signals. In addition, in embodiments, printed circuit board routing topologies place all of the individual channel input circuitry as close to the input connector as possible. In embodiments, a unique electrostatic protection for trigger and vibration inputs may be placed upfront on the Mux and DAQ hardware in order to dissipate the built up electric charge as the signal passed from the sensor to the hardware. In embodiments, the Mux and analog board may support high-amperage input using a design topology comprising wider traces and solid state relays for upfront circuitry.
In some systems multiplexers are afterthoughts and the quality of the signal coming from the multiplexer is not considered. As a result of a poor quality multiplexer, the quality of the signal can drop as much as 30 dB or more. Thus, substantial signal quality may be lost using a 24-bit DAQ that has a signal to noise ratio of 110 dB and if the signal to noise ratio drops to 80 dB in the Mux, it may not be much better than a 16-bit system from 20 years ago. In embodiments of this system, an important part at the front of the Mux is upfront signal conditioning on Mux for improved signal-to-noise ratio. Embodiments may perform signal conditioning (such as range/gain control, integration, filtering, etc.) on vibration as well as other signal inputs up front before Mux switching to achieve the highest signal-to-noise ratio.
In embodiments, in addition to providing a better signal, the multiplexer may provide a continuous monitor alarming feature. Truly continuous systems monitor every sensor all the time but tend to be expensive. Typical multiplexer systems only monitor a set number of channels at one time and switch from bank to bank of a larger set of sensors. As a result, the sensors not being currently collected are not being monitored; if a level increases the user may never know. In embodiments, a multiplexer may have a continuous monitor alarming feature by placing circuitry on the multiplexer that can measure input channel levels against known alarm conditions even when the data acquisition (“DAQ”) is not monitoring the input. In embodiments, continuous monitoring Mux bypass offers a mechanism whereby channels not being currently sampled by the Mux system may be continuously monitored for significant alarm conditions via a number of trigger conditions using filtered peak-hold circuits or functionally similar that are in turn passed on to the monitoring system in an expedient manner using hardware interrupts or other means. This, in essence, makes the system continuously monitoring, although without the ability to instantly capture data on the problem like a true continuous system. In embodiments, coupling this capability to alarm with adaptive scheduling techniques for continuous monitoring and the continuous monitoring system's software adapting and adjusting the data collection sequence based on statistics, analytics, data alarms and dynamic analysis may allow the system to quickly collect dynamic spectral data on the alarming sensor very soon after the alarm sounds.
Another restriction of typical multiplexers is that they may have a limited number of channels. In embodiments, use of distributed complex programmable logic device (“CPLD”) chips with dedicated bus for logic control of multiple Mux and data acquisition sections enables a CPLD to control multiple mux and DAQs so that there is no limit to the number of channels a system can handle Interfacing to multiple types of predictive maintenance and vibration transducers requires a great deal of switching. This includes AC/DC coupling, 4-20 interfacing, integrated electronic piezoelectric transducer, channel power-down (for conserving op-amp power), single-ended or differential grounding options, and so on. Also required is the control of digital pots for range and gain control, switches for hardware integration, AA filtering and triggering. This logic can be performed by a series of CPLD chips strategically located for the tasks they control. A single giant CPLD requires long circuit routes with a great deal of density at the single giant CPLD. In embodiments, distributed CPLDs not only address these concerns but offer a great deal of flexibility. A bus is created where each CPLD that has a fixed assignment has its own unique device address. In embodiments, multiplexers and DAQs can stack together offering additional input and output channels to the system. For multiple boards (e.g., for multiple Mux boards), jumpers are provided for setting multiple addresses. In another example, three bits permit up to 8 boards that are jumper configurable. In embodiments, a bus protocol is defined such that each CPLD on the bus can either be addressed individually or as a group.
Typical multiplexers may be limited to collecting only sensors in the same bank. For detailed analysis, this may be limiting as there is tremendous value in being able to simultaneously review data from sensors on the same machine. Current systems using conventional fixed bank multiplexers can only compare a limited number of channels (based on the number of channels per bank) that were assigned to a particular group at the time of installation. The only way to provide some flexibility is to either overlap channels or incorporate lots of redundancy in the system both of which can add considerable expense (in some cases an exponential increase in cost versus flexibility). The simplest Mux design selects one of many inputs and routes it into a single output line. A banked design would consist of a group of these simple building blocks, each handling a fixed group of inputs and routing to its respective output. Typically, the inputs are not overlapping so that the input of one Mux grouping cannot be routed into another. Unlike conventional Mux chips which typically switch a fixed group or banks of a fixed selection of channels into a single output (e.g., in groups of 2, 4, 8, etc.), a cross point Mux allows the user to assign any input to any output. Previously, crosspoint multiplexers were used for specialized purposes such as RGB digital video applications and were as a practical matter too noisy for analog applications such as vibration analysis; however more recent advances in the technology now make it feasible. Another advantage of the crosspoint Mux is the ability to disable outputs by putting them into a high impedance state. This is ideal for an output bus so that multiple Mux cards may be stacked, and their output buses joined together without the need for bus switches.
In embodiments, this may be addressed by use of an analog crosspoint switch for collecting variable groups of vibration input channels and providing a matrix circuit so the system may access any set of eight channels from the total number of input sensors.
In embodiments, the ability to control multiple multiplexers with use of distributed CPLD chips with dedicated bus for logic control of multiple Mux and data acquisition sections is enhanced with a hierarchical multiplexer which allows for multiple DAQ to collect data from multiple multiplexers. A hierarchical Mux may allow modularly output of more channels, such as 16, 24 or more to multiple of eight channel card sets. In embodiments, this allows for faster data collection as well as more channels of simultaneous data collection for more complex analysis. In embodiments, the Mux may be configured slightly to make it portable and use data acquisition parking features, which turns SV3X DAQ into a protected system embodiment.
In embodiments, once the signals leave the multiplexer and hierarchical Mux they move to the analog board where there are other enhancements. In embodiments, power saving techniques may be used such as: power-down of analog channels when not in use; powering down of component boards; power-down of analog signal processing op-amps for non-selected channels; powering down channels on the mother and the daughter analog boards. The ability to power down component boards and other hardware by the low-level firmware for the DAQ system makes high-level application control with respect to power-saving capabilities relatively easy. Explicit control of the hardware is always possible but not required by default. In embodiments, this power saving benefit may be of value to a protected system, especially if it is battery operated or solar powered.
In embodiments, in order to maximize the signal to noise ratio and provide the best data, a peak-detector for auto-scaling routed into a separate A/D will provide the system the highest peak in each set of data so it can rapidly scale the data to that peak. For vibration analysis purposes, the built-in A/D convertors in many microprocessors may be inadequate with regards to number of bits, number of channels or sampling frequency versus not slowing the microprocessor down significantly. Despite these limitations, it is useful to use them for purposes of auto-scaling. In embodiments, a separate A/D may be used that has reduced functionality and is cheaper. For each channel of input, after the signal is buffered (usually with the appropriate coupling: AC or DC) but before it is signal conditioned, the signal is fed directly into the microprocessor or low-cost A/D. Unlike the conditioned signal for which range, gain and filter switches are thrown, no switches are varied. This permits the simultaneous sampling of the auto-scaling data while the input data is signal conditioned, fed into a more robust external A/D, and directed into on-board memory using direct memory access (DMA) methods where memory is accessed without requiring a CPU. This significantly simplifies the auto-scaling process by not having to throw switches and then allow for settling time, which greatly slows down the auto-scaling process. Furthermore, the data may be collected simultaneously, which assures the best signal-to-noise ratio. The reduced number of bits and other features is usually more than adequate for auto-scaling purposes. In embodiments, improved integration using both analog and digital methods create an innovative hybrid integration which also improves or maintains the highest possible signal to noise ratio.
In embodiments, a section of the analog board may allow routing of a trigger channel, either raw or buffered, into other analog channels. This may allow a user to route the trigger to any of the channels for analysis and trouble shooting. Systems may have trigger channels for the purposes of determining relative phase between various input data sets or for acquiring significant data without the needless repetition of unwanted input. In embodiments, digitally controlled relays may be used to switch either the raw or buffered trigger signal into one of the input channels. It may be desirable to examine the quality of the triggering pulse because it may be corrupted for a variety of reasons including inadequate placement of the trigger sensor, wiring issues, faulty setup issues such as a dirty piece of reflective tape if using an optical sensor, and so on. The ability to look at either the raw or buffered signal may offer an excellent diagnostic or debugging vehicle. It also can offer some improved phase analysis capability by making use of the recorded data signal for various signal processing techniques such as variable speed filtering algorithms.
In embodiments, once the signals leave the analog board, the signals move into the delta-sigma board where precise voltage reference for A/D zero reference offers more accurate direct current sensor data. The delta sigma's high speeds also provide for using higher input oversampling for delta-sigma A/D for lower sampling rate outputs to minimize antialiasing filter requirements. Lower oversampling rates can be used for higher sampling rates. For example, a 3rd order AA filter set for the lowest sampling requirement for 256 Hz (Fmax of 100 Hz) is then adequate for Fmax ranges of 200 and 500 Hz. Another higher-cutoff AA filter can then be used for Fmax ranges from 1 kHz and higher (with a secondary filter kicking in at 2.56× the highest sampling rate of 128 kHz). In embodiments, a CPLD may be used as a clock-divider for a delta-sigma A/D to achieve lower sampling rates without the need for digital resampling. In embodiments, a high-frequency crystal reference can be divided down to lower frequencies by employing a CPLD as a programmable clock divider. The accuracy of the divided down lower frequencies is even more accurate than the original source relative to their longer time periods. This also minimizes or removes the need for resampling processing by the delta-sigma A/D.
In embodiments, the data then moves from the delta-sigma board to the Jennic™ board where phase relative to input and trigger channels using on-board timers may be digitally derived. In embodiments, the Jennic™ board also has the ability to store calibration data and system maintenance repair history data in an on-board card set. In embodiments, the Jennic™ board will enable acquiring long blocks of data at high-sampling rate as opposed to multiple sets of data taken at different sampling rates so it can stream data and acquire long blocks of data for advanced analysis in the future.
In embodiments, after the signal moves through the Jennic™ board it may then be transmitted to the computer. In embodiments, the computer software will be used to add intelligence to the system starting with an expert system GUI. The GUI will offer a graphical expert system with simplified user interface for defining smart bands and diagnoses which facilitate anyone to develop complex analytics. In embodiments, this user interface may revolve around smart bands, which are a simplified approach to complex yet flexible analytics for the general user. In embodiments, the smart bands may pair with a self-learning neural network for an even more advanced analytical approach. In embodiments, this system may use the machine's hierarchy for additional analytical insight. One critical part of predictive maintenance is the ability to learn from known information during repairs or inspections. In embodiments, graphical approaches for back calculations may improve the smart bands and correlations based on a known fault or problem.
In embodiments, there is a smart route which adapts which sensors it collects simultaneously in order to gain additional correlative intelligence. In embodiments, smart operational data store (“ODS”) allows the system to elect to gather data to perform operational deflection shape analysis in order to further examine the machinery condition. In embodiments, adaptive scheduling techniques allow the system to change the scheduled data collected for full spectral analysis across a number (e.g., eight), of correlative channels. In embodiments, the system may provide data to enable extended statistics capabilities for continuous monitoring as well as ambient local vibration for analysis that combines ambient temperature and local temperature and vibration levels changes for identifying machinery issues.
In embodiments, a data acquisition device may be controlled by a personal computer (PC) to implement the desired data acquisition commands. In embodiments, the DAQ box may be self-sufficient and can acquire, process, analyze and monitor independent of external PC control. Embodiments may include secure digital (SD) card storage. In embodiments, significant additional storage capability may be provided by utilizing an SD card. This may prove critical for monitoring applications where critical data may be stored permanently. Also, if a power failure should occur, the most recent data may be stored despite the fact that it was not off-loaded to another system.
A current trend has been to make DAQ systems as communicative as possible with the outside world usually in the form of networks including wireless. In the past it was common to use a dedicated bus to control a DAQ system with either a microprocessor or microcontroller/microprocessor paired with a PC. In embodiments, a DAQ system may comprise one or more microprocessor/microcontrollers, specialized microcontrollers/microprocessors, or dedicated processors focused primarily on the communication aspects with the outside world. These include USB, Ethernet and wireless with the ability to provide an IP address or addresses in order to host a webpage. All communications with the outside world are then accomplished using a simple text based menu. The usual array of commands (in practice more than a hundred) such as InitializeCard, AcquireData, StopAcquisition, RetrieveCalibration Info, and so on, would be provided.
In embodiments, intense signal processing activities including resampling, weighting, filtering, and spectrum processing may be performed by dedicated processors such as field-programmable gate array (“FPGAs”), digital signal processor (“DSP”), microprocessors, micro-controllers, or a combination thereof. In embodiments, this subsystem may communicate via a specialized hardware bus with the communication processing section. It will be facilitated with dual-port memory, semaphore logic, and so on. This embodiment will not only provide a marked improvement in efficiency but can significantly improve the processing capability, including the streaming of the data as well other high-end analytical techniques. This negates the need for constantly interrupting the main processes which include the control of the signal conditioning circuits, triggering, raw data acquisition using the A/D, directing the A/D output to the appropriate on-board memory and processing that data.
Embodiments may include sensor overload identification. A need exists for monitoring systems to identify when the sensor is overloading. There may be situations involving high-frequency inputs that will saturate a standard 100 mv/g sensor (which is most commonly used in the industry) and having the ability to sense the overload improves data quality for better analysis. A monitoring system may identify when their system is overloading, but in embodiments, the system may look at the voltage of the sensor to determine if the overload is from the sensor, enabling the user to get another sensor better suited to the situation, or gather the data again.
Embodiments may include radio frequency identification (“RFID”) and an inclinometer or accelerometer on a sensor so the sensor can indicate what machine/bearing it is attached to and what direction such that the software can automatically store the data without the user input. In embodiments, users could put the system on any machine or machines and the system would automatically set itself up and be ready for data collection in seconds.
Embodiments may include ultrasonic online monitoring by placing ultrasonic sensors inside transformers, motor control centers, breakers and the like and monitoring, via a sound spectrum, continuously looking for patterns that identify arcing, corona and other electrical issues indicating a break down or issue. Embodiments may include providing continuous ultrasonic monitoring of rotating elements and bearings of an energy production facility. In embodiments, an analysis engine may be used in ultrasonic online monitoring as well as identifying other faults by combining the ultrasonic data with other parameters such as vibration, temperature, pressure, heat flux, magnetic fields, electrical fields, currents, voltage, capacitance, inductance, and combinations (e.g., simple ratios) of the same, among many others.
Embodiments of the methods and systems disclosed herein may include use of an analog crosspoint switch for collecting variable groups of vibration input channels. For vibration analysis, it is useful to obtain multiple channels simultaneously from vibration transducers mounted on different parts of a machine (or machines) in multiple directions. By obtaining the readings at the same time, for example, the relative phases of the inputs may be compared for the purpose of diagnosing various mechanical faults. Other types of cross channel analyses such as cross-correlation, transfer functions, Operating Deflection Shape (“ODS”) may also be performed.
Embodiments of the methods and systems disclosed herein may include precise voltage reference for A/D zero reference. Some A/D chips provide their own internal zero voltage reference to be used as a mid-scale value for external signal conditioning circuitry to ensure that both the A/D and external op-amps use the same reference. Although this sounds reasonable in principle, there are practical complications. In many cases these references are inherently based on a supply voltage using a resistor-divider. For many current systems, especially those whose power is derived from a PC via USB or similar bus, this provides for an unreliable reference, as the supply voltage will often vary quite significantly with load. This is especially true for delta-sigma A/D chips which necessitate increased signal processing. Although the offsets may drift together with load, a problem arises if one wants to calibrate the readings digitally. It is typical to modify the voltage offset expressed as counts coming from the A/D digitally to compensate for the DC drift. However, for this case, if the proper calibration offset is determined for one set of loading conditions, they will not apply for other conditions. An absolute DC offset expressed in counts will no longer be applicable. As a result, it becomes necessary to calibrate for all loading conditions which becomes complex, unreliable, and ultimately unmanageable. In embodiments, an external voltage reference is used which is simply independent of the supply voltage to use as the zero offset.
In embodiments, the system provides a phase-lock-loop band pass tracking filter method for obtaining slow-speed RPMs and phase for balancing purposes to remotely balance slow speed machinery, such as in paper mills, as well as offering additional analysis from its data. For balancing purposes, it is sometimes necessary to balance at very slow speeds. A typical tracking filter may be constructed based on a phase-lock loop or PLL design; however, stability and speed range are overriding concerns. In embodiments, a number of digitally controlled switches are used for selecting the appropriate RC and damping constants. The switching can be done all automatically after measuring the frequency of the incoming tach signal. Embodiments of the methods and systems disclosed herein may include digital derivation of phase relative to input and trigger channels using on-board timers. In embodiments, digital phase derivation uses digital timers to ascertain an exact delay from a trigger event to the precise start of data acquisition. This delay, or offset, then, is further refined using interpolation methods to obtain an even more precise offset which is then applied to the analytically determined phase of the acquired data such that the phase is “in essence” an absolute phase with precise mechanical meaning useful for among other things, one-shot balancing, alignment analysis, and so on.
Embodiments of the methods and systems disclosed herein may include signal processing firmware/hardware. In embodiments, long blocks of data may be acquired at high-sampling rate as opposed to multiple sets of data taken at different sampling rates. Typically, in modern route collection for vibration analysis, it is customary to collect data at a fixed sampling rate with a specified data length. The sampling rate and data length may vary from route point to point based on the specific mechanical analysis requirements at hand. For example, a motor may require a relatively low sampling rate with high resolution to distinguish running speed harmonics from line frequency harmonics. The practical trade-off here though is that it takes more collection time to achieve this improved resolution. In contrast, some high-speed compressors or gear sets require much higher sampling rates to measure the amplitudes of relatively higher frequency data although the precise resolution may not be as necessary. Ideally, however, it would be better to collect a very long sample length of data at a very high-sampling rate. When digital acquisition devices were first popularized in the early 1980's, the A/D sampling, digital storage, and computational abilities were not close to what they are today, so compromises were made between the time required for data collection and the desired resolution and accuracy. It was because of this limitation that some analysts in the field even refused to give up their analog tape recording systems, which did not suffer as much from these same digitizing drawbacks. A few hybrid systems were employed that would digitize the play back of the recorded analog data at multiple sampling rates and lengths desired, though these systems were admittedly less automated. The more common approach, as mentioned earlier, is to balance data collection time with analysis capability and digitally acquire the data blocks at multiple sampling rates and sampling lengths and digitally store these blocks separately. In embodiments, a long data length of data can be collected at the highest practical sampling rate (e.g., 102.4 kHz; corresponding to a 40 kHz Fmax) and stored. This long block of data can be acquired in the same amount of time as the shorter length of the lower sampling rates utilized by a priori methods so that there is no effective delay added to the sampling at the measurement point, always a concern in route collection. In embodiments, analog tape recording of data is digitally simulated with such a precision that it can be in effect considered continuous or “analog” for many purposes, including for purposes of embodiments of the present disclosure, except where context indicates otherwise.
Embodiments of the methods and systems disclosed herein may include storage of calibration data and maintenance history on-board card sets. Many data acquisition devices which rely on interfacing to a PC to function store their calibration coefficients on the PC. This is especially true for complex data acquisition devices whose signal paths are many and therefore whose calibration tables can be quite large. In embodiments, calibration coefficients are stored in flash memory which will remember this data or any other significant information for that matter, for all practical purposes, permanently. This information may include nameplate information such as serial numbers of individual components, firmware or software version numbers, maintenance history, and the calibration tables. In embodiments, no matter which computer the box is ultimately connected to, the DAQ box remains calibrated and continues to hold all of this critical information. The PC or external device may poll for this information at any time for implantation or information exchange purposes.
Embodiments of the methods and systems disclosed herein may include rapid route creation taking advantage of hierarchical templates. In the field of vibration monitoring, as well as parametric monitoring in general, it is necessary to establish in a database or functional equivalent the existence of data monitoring points. These points are associated a variety of attributes including the following categories: transducer attributes, data collection settings, machinery parameters and operating parameters. The transducer attributes would include probe type, probe mounting type and probe mounting direction or axis orientation. Data collection attributes associated with the measurement would involve a sampling rate, data length, integrated electronic piezoelectric probe power and coupling requirements, hardware integration requirements, 4-20 or voltage interfacing, range and gain settings (if applicable), filter requirements, and so on. Machinery parametric requirements relative to the specific point would include such items as operating speed, bearing type, bearing parametric data which for a rolling element bearing includes the pitch diameter, number of balls, inner race, and outer-race diameters. For a tilting pad bearing, this would include the number of pads and so on. For measurement points on a piece of equipment such as a gearbox, needed parameters would include, for example, the number of gear teeth on each of the gears. For induction motors, it would include the number of rotor bars and poles; for compressors, the number of blades and/or vanes; for fans, the number of blades. For belt/pulley systems, the number of belts as well as the relevant belt-passing frequencies may be calculated from the dimensions of the pulleys and pulley center-to-center distance. For measurements near couplings, the coupling type and number of teeth in a geared coupling may be necessary, and so on. Operating parametric data would include operating load, which may be expressed in megawatts, flow (either air or fluid), percentage, horsepower, feet-per-minute, and so on. Operating temperatures both ambient and operational, pressures, humidity, and so on, may also be relevant. As can be seen, the setup information required for an individual measurement point can be quite large. It is also crucial to performing any legitimate analysis of the data. Machinery, equipment, and bearing specific information are essential for identifying fault frequencies as well as anticipating the various kinds of specific faults to be expected. The transducer attributes as well as data collection parameters are vital for properly interpreting the data along with providing limits for the type of analytical techniques suitable. The traditional means of entering this data has been manual and quite tedious, usually at the lowest hierarchical level (for example, at the bearing level with regards to machinery parameters), and at the transducer level for data collection setup information. It cannot be stressed enough, however, the importance of the hierarchical relationships necessary to organize data—both for analytical and interpretive purposes as well as the storage and movement of data. Here, we are focusing primarily on the storage and movement of data. By its nature, the aforementioned setup information is extremely redundant at the level of the lowest hierarchies; however, because of its strong hierarchical nature, it can be stored quite efficiently in that form. In embodiments, hierarchical nature can be utilized when copying data in the form of templates. As an example, hierarchical storage structure suitable for many purposes is defined from general to specific of company, plant or site, unit or process, machine, equipment, shaft element, bearing, and transducer. It is much easier to copy data associated with a particular machine, piece of equipment, shaft element or bearing than it is to copy only at the lowest transducer level. In embodiments, the system not only stores data in this hierarchical fashion, but robustly supports the rapid copying of data using these hierarchical templates. Similarity of elements at specific hierarchical levels lends itself to effective data storage in hierarchical format. For example, so many machines have common elements such as motors, gearboxes, compressors, belts, fans, and so on. More specifically, many motors can be easily classified as induction, DC, fixed or variable speed. Many gearboxes can be grouped into commonly occurring groupings such as input/output, input pinion/intermediate pinion/output pinion, 4-posters, and so on. Within a plant or company, there are many similar types of equipment purchased and standardized on for both cost and maintenance reasons. This results in an enormous overlapping of similar types of equipment and, as a result, offers a great opportunity for taking advantage of a hierarchical template approach.
Embodiments of the methods and systems disclosed herein may include smart bands. Smart bands refer to any processed signal characteristics derived from any dynamic input or group of inputs for the purposes of analyzing the data and achieving the correct diagnoses. Furthermore, smart bands may even include mini or relatively simple diagnoses for the purposes of achieving a more robust and complex one. Historically, in the field of mechanical vibration analysis, Alarm Bands have been used to define spectral frequency bands of interest for the purposes of analyzing and/or trending significant vibration patterns. The Alarm Band typically consists of a spectral (amplitude plotted against frequency) region defined between a low and high frequency border. The amplitude between these borders is summed in the same manner for which an overall amplitude is calculated. A Smart Band is more flexible in that it not only refers to a specific frequency band but can also refer to a group of spectral peaks such as the harmonics of a single peak, a true-peak level or crest factor derived from a time waveform, an overall derived from a vibration envelope spectrum or other specialized signal analysis technique or a logical combination (AND, OR, XOR, etc.) of these signal attributes. In addition, a myriad assortment of other parametric data, including system load, motor voltage and phase information, bearing temperature, flow rates, and the like, can likewise be used as the basis for forming additional smart bands. In embodiments, Smart Band symptoms may be used as building blocks for an expert system whose engine would utilize these inputs to derive diagnoses. Some of these mini-diagnoses may then in turn be used as Smart-Band symptoms (smart bands can include even diagnoses) for more generalized diagnoses.
Embodiments of the methods and systems disclosed herein may include a neural net expert system using smart bands. Typical vibration analysis engines are rule-based (i.e., they use a list of expert rules which, when met, trigger specific diagnoses). In contrast, a neural approach utilizes the weighted triggering of multiple input stimuli into smaller analytical engines or neurons which in turn feed a simplified weighted output to other neurons. The output of these neurons can be also classified as smart bands which in turn feed other neurons. This produces a more layered approach to expert diagnosing as opposed to the one-shot approach of a rule-based system. In embodiments, the expert system utilizes this neural approach using smart bands; however, it does not preclude rule-based diagnoses being reclassified as smart bands as further stimuli to be utilized by the expert system. From this point-of-view, it can be overviewed as a hybrid approach, although at the highest level it is essentially neural.
Embodiments of the methods and systems disclosed herein may include use of database hierarchy in analysis smart band symptoms and diagnoses may be assigned to various hierarchical database levels. For example, a smart band may be called “Looseness” at the bearing level, trigger “Looseness” at the equipment level, and trigger “Looseness” at the machine level. Another example would be having a smart band diagnosis called “Horizontal Plane Phase Flip” across a coupling and generate a smart band diagnosis of “Vertical Coupling Misalignment” at the machine level.
Embodiments of the methods and systems disclosed herein may include expert system GUIs. In embodiments, the system undertakes a graphical approach to defining smart bands and diagnoses for the expert system. The entry of symptoms, rules, or more generally smart bands for creating a particular machine diagnosis, may be tedious and time consuming. One means of making the process more expedient and efficient is to provide a graphical means by use of wiring. The proposed graphical interface consists of four major components: a symptom parts bin, diagnoses bin, tools bin, and graphical wiring area (“GWA”). In embodiments, a symptom parts bin includes various spectral, waveform, envelope and any type of signal processing characteristic or grouping of characteristics such as a spectral peak, spectral harmonic, waveform true-peak, waveform crest-factor, spectral alarm band, and so on. Each part may be assigned additional properties. For example, a spectral peak part may be assigned a frequency or order (multiple) of running speed. Some parts may be pre-defined or user defined such as a 1×, 2×, 3× running speed, 1×, 2×, 3× gear mesh, 1×, 2×, 3× blade pass, number of motor rotor bars×running speed, and so on.
In embodiments, the diagnoses bin includes various pre-defined as well as user-defined diagnoses such as misalignment, imbalance, looseness, bearing faults, and so on. Like parts, diagnoses may also be used as parts for the purposes of building more complex diagnoses. In embodiments, the tools bin includes logical operations such as AND, OR, XOR, etc. or other ways of combining the various parts listed above such as Find Max, Find Min, Interpolate, Average, other Statistical Operations, etc. In embodiments, a graphical wiring area includes parts from the parts bin or diagnoses from the diagnoses bin and may be combined using tools to create diagnoses. The various parts, tools and diagnoses will be represented with icons which are simply graphically wired together in the desired manner.
Embodiments of the methods and systems disclosed herein may include a graphical approach for back-calculation definition. In embodiments, the expert system also provides the opportunity for the system to learn. If one already knows that a unique set of stimuli or smart bands corresponds to a specific fault or diagnosis, then it is possible to back-calculate a set of coefficients that when applied to a future set of similar stimuli would arrive at the same diagnosis. In embodiments, if there are multiple sets of data, a best-fit approach may be used. Unlike the smart band GUI, this embodiment will self-generate a wiring diagram. In embodiments, the user may tailor the back-propagation approach settings and use a database browser to match specific sets of data with the desired diagnoses. In embodiments, the desired diagnoses may be created or custom tailored with a smart band GUI. In embodiments, after that, a user may press the GENERATE button and a dynamic wiring of the symptom-to-diagnosis may appear on the screen as it works through the algorithms to achieve the best fit. In embodiments, when complete, a variety of statistics are presented which detail how well the mapping process proceeded. In some cases, no mapping may be achieved if, for example, the input data was all zero or the wrong data (mistakenly assigned) and so on. Embodiments of the methods and systems disclosed herein may include bearing analysis methods. In embodiments, bearing analysis methods may be used in conjunction with a computer aided design (“CAD”), predictive deconvolution, minimum variance distortionless response (“MVDR”) and spectrum sum-of-harmonics.
In recent years, there has been a strong drive to save power which has resulted in an influx of variable frequency drives and variable speed machinery. In embodiments, a bearing analysis method is provided. In embodiments, torsional vibration detection and analysis is provided utilizing transitory signal analysis to provide an advanced torsional vibration analysis for a more comprehensive way to diagnose machinery where torsional forces are relevant (such as machinery with rotating components). Due primarily to the decrease in cost of motor speed control systems, as well as the increased cost and consciousness of energy-usage, it has become more economically justifiable to take advantage of the potentially vast energy savings of load control. Unfortunately, one frequently overlooked design aspect of this issue is that of vibration. When a machine is designed to run at only one speed, it is far easier to design the physical structure accordingly so as to avoid mechanical resonances both structural and torsional, each of which can dramatically shorten the mechanical health of a machine. This would include such structural characteristics as the types of materials to use, their weight, stiffening member requirements and placement, bearing types, bearing location, base support constraints, etc. Even with machines running at one speed, designing a structure so as to minimize vibration can prove a daunting task, potentially requiring computer modeling, finite-element analysis, and field testing. By throwing variable speeds into the mix, in many cases, it becomes impossible to design for all desirable speeds. The problem then becomes one of minimization, e.g., by speed avoidance. This is why many modern motor controllers are typically programmed to skip or quickly pass through specific speed ranges or bands. Embodiments may include identifying speed ranges in a vibration monitoring system. Non-torsional, structural resonances are typically fairly easy to detect using conventional vibration analysis techniques. However, this is not the case for torsion. One special area of current interest is the increased incidence of torsional resonance problems, apparently due to the increased torsional stresses of speed change as well as the operation of equipment at torsional resonance speeds. Unlike non-torsional structural resonances which generally manifest their effect with dramatically increased casing or external vibration, torsional resonances generally show no such effect. In the case of a shaft torsional resonance, the twisting motion induced by the resonance may only be discernible by looking for speed and/or phase changes. The current standard methodology for analyzing torsional vibration involves the use of specialized instrumentation. Methods and systems disclosed herein allow analysis of torsional vibration without such specialized instrumentation. This may consist of shutting the machine down and employing the use of strain gauges and/or other special fixturing such as speed encoder plates and/or gears. Friction wheels are another alternative, but they typically require manual implementation and a specialized analyst. In general, these techniques can be prohibitively expensive and/or inconvenient. An increasing prevalence of continuous vibration monitoring systems due to decreasing costs and increasing convenience (e.g., remote access) exists. In embodiments, there is an ability to discern torsional speed and/or phase variations with just the vibration signal. In embodiments, transient analysis techniques may be utilized to distinguish torsionally induced vibrations from mere speed changes due to process control. In embodiments, factors for discernment might focus on one or more of the following aspects: the rate of speed change due to variable speed motor control would be relatively slow, sustained and deliberate; torsional speed changes would tend to be short, impulsive and not sustained; torsional speed changes would tend to be oscillatory, most likely decaying exponentially, process speed changes would not; and smaller speed changes associated with torsion relative to the shaft's rotational speed which suggest that monitoring phase behavior would show the quick or transient speed bursts in contrast to the slow phase changes historically associated with ramping a machine's speed up or down (as typified with Bode or Nyquist plots).
Embodiments of the methods and systems disclosed herein may include improved integration using both analog and digital methods. When a signal is digitally integrated using software, essentially the spectral low-end frequency data has its amplitude multiplied by a function which quickly blows up as it approaches zero and creates what is known in the industry as a “ski-slope” effect. The amplitude of the ski-slope is essentially the noise floor of the instrument. The simple remedy for this is the traditional hardware integrator, which can perform at signal-to-noise ratios much greater than that of an already digitized signal. It can also limit the amplification factor to a reasonable level so that multiplication by very large numbers is essentially prohibited. However, at high frequencies where the frequency becomes large, the original amplitude which may be well above the noise floor is multiplied by a very small number (1/f) that plunges it well below the noise floor. The hardware integrator has a fixed noise floor that although low floor does not scale down with the now lower amplitude high-frequency data. In contrast, the same digital multiplication of a digitized high-frequency signal also scales down the noise floor proportionally. In embodiments, hardware integration may be used below the point of unity gain where (at a value usually determined by units and/or desired signal to noise ratio based on gain) and software integration may be used above the value of unity gain to produce an ideal result. In embodiments, this integration is performed in the frequency domain. In embodiments, the resulting hybrid data can then be transformed back into a waveform which should be far superior in signal-to-noise ratio when compared to either hardware integrated or software integrated data. In embodiments, the strengths of hardware integration are used in conjunction with those of digital software integration to achieve the maximum signal-to-noise ratio. In embodiments, the first order gradual hardware integrator high pass filter along with curve fitting allow some relatively low frequency data to get through while reducing or eliminating the noise, allowing very useful analytical data that steep filters kill to be salvaged.
Embodiments of the methods and systems disclosed herein may include adaptive scheduling techniques for continuous monitoring. Continuous monitoring is often performed with an up-front Mux whose purpose it is to select a few channels of data among many to feed the hardware signal processing, A/D, and processing components of a DAQ system. This is done primarily out of practical cost considerations. The tradeoff is that all of the points are not monitored continuously (although they may be monitored to a lesser extent via alternative hardware methods). In embodiments, multiple scheduling levels are provided. In embodiments, at the lowest level, which is continuous for the most part, all of the measurement points will be cycled through in round-robin fashion. For example, if it takes 30 seconds to acquire and process a measurement point and there are 30 points, then each point is serviced once every 15 minutes; however, if a point should alarm by whatever criteria the user selects, its priority level can be increased so that it is serviced more often. As there can be multiple grades of severity for each alarm, so can there me multiple levels of priority with regards to monitoring. In embodiments, more severe alarms will be monitored more frequently. In embodiments, a number of additional high-level signal processing techniques can be applied at less frequent intervals. Embodiments may take advantage of the increased processing power of a PC and the PC can temporarily suspend the round-robin route collection (with its multiple tiers of collection) process and stream the required amount of data for a point of its choosing. Embodiments may include various advanced processing techniques such as envelope processing, wavelet analysis, as well as many other signal processing techniques. In embodiments, after acquisition of this data, the DAQ card set will continue with its route at the point it was interrupted. In embodiments, various PC scheduled data acquisitions will follow their own schedules which will be less frequency than the DAQ card route. They may be set up hourly, daily, by number of route cycles (for example, once every 10 cycles) and also increased scheduling-wise based on their alarm severity priority or type of measurement (e.g., motors may be monitored differently than fans).
Embodiments of the methods and systems disclosed herein may include data acquisition parking features. In embodiments, a data acquisition box used for route collection, real time analysis and in general as an acquisition instrument can be detached from its PC (tablet or otherwise) and powered by an external power supply or suitable battery. In embodiments, the data collector still retains continuous monitoring capability and its on-board firmware can implement dedicated monitoring functions for an extended period of time or can be controlled remotely for further analysis. Embodiments of the methods and systems disclosed herein may include extended statistical capabilities for continuous monitoring.
Embodiments of the methods and systems disclosed herein may include ambient sensing plus local sensing plus vibration for analysis. In embodiments, ambient environmental temperature and pressure, sensed temperature and pressure may be combined with long/medium term vibration analysis for prediction of any of a range of conditions or characteristics. Variants may add infrared sensing, infrared thermography, ultrasound, and many other types of sensors and input types in combination with vibration or with each other. Embodiments of the methods and systems disclosed herein may include a smart route. In embodiments, the continuous monitoring system's software will adapt/adjust the data collection sequence based on statistics, analytics, data alarms and dynamic analysis. Typically, the route is set based on the channels the sensors are attached to. In embodiments, with the crosspoint switch, the Mux can combine any input Mux channels to the (e.g., eight) output channels. In embodiments, as channels go into alarm or the system identifies key deviations, it will pause the normal route set in the software to gather specific simultaneous data, from the channels sharing key statistical changes, for more advanced analysis. Embodiments include conducting a smart ODS or smart transfer function.
Embodiments of the methods and systems disclosed herein may include smart ODS and one or more transfer functions. In embodiments, due to a system's multiplexer and crosspoint switch, an ODS, a transfer function, or other special tests on all the vibration sensors attached to a machine/structure can be performed and show exactly how the machine's points are moving in relationship to each other. In embodiments, 40-50 kHz and longer data lengths (e.g., at least one minute) may be streamed, which may reveal different information than what a normal ODS or transfer function will show. In embodiments, the system will be able to determine, based on the data/statistics/analytics to use, the smart route feature that breaks from the standard route and conducts an ODS across a machine, structure or multiple machines and structures that might show a correlation because the conditions/data directs it. In embodiments, for the transfer functions there may be an impact hammer used on one channel and then compared against other vibration sensors on the machine. In embodiments, the system may use the condition changes such as load, speed, temperature or other changes in the machine or system to conduct the transfer function. In embodiments, different transfer functions may be compared to each other over time. In embodiments, difference transfer functions may be strung together like a movie that may show how the machinery fault changes, such as a bearing that could show how it moves through the four stages of bearing failure and so on. Embodiments of the methods and systems disclosed herein may include a hierarchical Mux.
With reference to
In embodiments, the machine 2020 can further include a housing 2100 that can contain a drive motor 2110 that can drive a shaft 2120. The shaft 2120 can be supported for rotation or oscillation by a set of bearings 2130, such as including a first bearing 2140 and a second bearing 2150. A data collection module 2160 can connect to (or be resident on) the machine 2020. In one example, the data collection module 2160 can be located and accessible through a cloud network facility 2170, can collect the waveform data 2010 from the machine 2020, and deliver the waveform data 2010 to a remote location. A working end 2180 of the drive shaft 2120 of the machine 2020 can drive a windmill, a fan, a pump, a drill, a gear system, a drive system, or other working element, as the techniques described herein can apply to a wide range of machines, equipment, tools, or the like that include rotating or oscillating elements. In other instances, a generator can be substituted for the motor 2110, and the working end of the drive shaft 2120 can direct rotational energy to the generator to generate power, rather than consume it.
In embodiments, the waveform data 2010 can be obtained using a predetermined route format based on the layout of the machine 2020. The waveform data 2010 may include data from the single axis sensor 2030 and the three-axis sensor 2050. The single-axis sensor 2030 can serve as a reference probe with its one channel of data and can be fixed at the unchanging location 2040 on the machine under survey. The three-axis sensor 2050 can serve as a tri-axial probe (e.g., three orthogonal axes) with its three channels of data and can be moved along a predetermined diagnostic route format from one test point to the next test point. In one example, both sensors 2030, 2050 can be mounted manually to the machine 2020 and can connect to a separate portable computer in certain service examples. The reference probe can remain at one location while the user can move the tri-axial vibration probe along the predetermined route, such as from bearing-to-bearing on a machine. In this example, the user is instructed to locate the sensors at the predetermined locations to complete the survey (or portion thereof) of the machine.
With reference to
In further examples, the sensors and data acquisition modules and equipment can be integral to, or resident on, the rotating machine. By way of these examples, the machine can contain many single axis sensors and many tri-axial sensors at predetermined locations. The sensors can be originally installed equipment and provided by the original equipment manufacturer or installed at a different time in a retrofit application. The data collection module 2160, or the like, can select and use one single axis sensor and obtain data from it exclusively during the collection of waveform data 2010 while moving to each of the tri-axial sensors. The data collection module 2160 can be resident on the machine 2020 and/or connect via the cloud network facility 2170.
With reference to
In embodiments, a second reference sensor can be used, and a fifth channel of data can be collected. As such, the single-axis sensor can be the first channel and tri-axial vibration can occupy the second, the third, and the fourth data channels. This second reference sensor, like the first, can be a single axis sensor, such as an accelerometer. In embodiments, the second reference sensor, like the first reference sensor, can remain in the same location on the machine for the entire vibration survey on that machine. The location of the first reference sensor (i.e., the single axis sensor) may be different than the location of the second reference sensors (i.e., another single axis sensor). In certain examples, the second reference sensor can be used when the machine has two shafts with different operating speeds, with the two reference sensors being located on the two different shafts. In accordance with this example, further single-axis reference sensors can be employed at additional but different unchanging locations associated with the rotating machine.
In embodiments, the waveform data can be transmitted electronically in a gap-free free format at a significantly high rate of sampling for a relatively longer period of time. In one example, the period of time is 60 seconds to 120 seconds. In another example, the rate of sampling is 100 kHz with a maximum resolvable frequency (Fmax) of 40 kHz. It will be appreciated in light of this disclosure that the waveform data can be shown to approximate more closely some of the wealth of data available from previous instances of analog recording of waveform data.
In embodiments, sampling, band selection, and filtering techniques can permit one or more portions of a long stream of data (i.e., one to two minutes in duration) to be under sampled or over sampled to realize varying effective sampling rates. To this end, interpolation and decimation can be used to further realize varying effective sampling rates. For example, oversampling may be applied to frequency bands that are proximal to rotational or oscillational operating speeds of the sampled machine, or to harmonics thereof, as vibration effects may tend to be more pronounced at those frequencies across the operating range of the machine. In embodiments, the digitally-sampled data set can be decimated to produce a lower sampling rate. It will be appreciated in light of the disclosure that decimate in this context can be the opposite of interpolate. In embodiments, decimating the data set can include first applying a low-pass filter to the digitally-sampled data set and then undersampling the data set.
In one example, a sample waveform at 100 Hz can be undersampled at every tenth point of the digital waveform to produce an effective sampling rate of 10 Hz, but the remaining nine points of that portion of the waveform are effectively discarded and not included in the modeling of the sample waveform. Moreover, this type of bare undersampling can create ghost frequencies due to the undersampling rate (i.e., 10 Hz) relative to the 100 Hz sample waveform.
Most hardware for analog-to-digital conversions uses a sample-and-hold circuit that can charge up a capacitor for a given amount of time such that an average value of the waveform is determined over a specific change in time. It will be appreciated in light of the disclosure that the value of the waveform over the specific change in time is not linear but more similar to a cardinal sinusoidal (“sinc”) function; therefore, it can be shown that more emphasis can be placed on the waveform data at the center of the sampling interval with exponential decay of the cardinal sinusoidal signal occurring from its center.
By way of the above example, the sample waveform at 100 Hz can be hardware-sampled at 10 Hz and therefore each sampling point is averaged over 100 milliseconds (e.g., a signal sampled at 100 Hz can have each point averaged over 10 milliseconds). In contrast to the effective discarding of nine out of the ten data points of the sampled waveform as discussed above, the present disclosure can include weighing adjacent data. The adjacent data can refer to the sample points that were previously discarded and the one remaining point that was retained. In one example, a low pass filter can average the adjacent sample data linearly, i.e., determining the sum of every ten points and then dividing that sum by ten. In a further example, the adjacent data can be weighted with a sinc function. The process of weighting the original waveform with the sinc function can be referred to as an impulse function, or can be referred to in the time domain as a convolution.
The present disclosure can be applicable to not only digitizing a waveform signal based on a detected voltage, but can also be applicable to digitizing waveform signals based on current waveforms, vibration waveforms, and image processing signals including video signal rasterization. In one example, the resizing of a window on a computer screen can be decimated, albeit in at least two directions. In these further examples, it will be appreciated that undersampling by itself can be shown to be insufficient. To that end, oversampling or upsampling by itself can similarly be shown to be insufficient, such that interpolation can be used like decimation but in lieu of only undersampling by itself.
It will be appreciated in light of the disclosure that interpolation in this context can refer to first applying a low pass filter to the digitally-sampled waveform data and then upsampling the waveform data. It will be appreciated in light of the disclosure that real-world examples can often require the use of use non-integer factors for decimation or interpolation, or both. To that end, the present disclosure includes interpolating and decimating sequentially in order to realize a non-integer factor rate for interpolating and decimating. In one example, interpolating and decimating sequentially can define applying a low-pass filter to the sample waveform, then interpolating the waveform after the low-pass filter, and then decimating the waveform after the interpolation. In embodiments, the vibration data can be looped to purposely emulate conventional tape recorder loops, with digital filtering techniques used with the effective splice to facilitate longer analyses. It will be appreciated in light of the disclosure that the above techniques do not preclude waveform, spectrum, and other types of analyses to be processed and displayed with a GUI of the user at the time of collection. It will be appreciated in light of the disclosure that newer systems can permit this functionality to be performed in parallel to the high-performance collection of the raw waveform data.
With respect to time of collection issues, it will be appreciated that older systems using the compromised approach of improving data resolution, by collecting at different sampling rates and data lengths, do not in fact save as much time as expected. To that end, every time the data acquisition hardware is stopped and started, latency issues can be created, especially when there is hardware auto-scaling performed. The same can be true with respect to data retrieval of the route information (i.e., test locations) that is often in a database format and can be exceedingly slow. The storage of the raw data in bursts to disk (whether solid state or otherwise) can also be undesirably slow.
In contrast, the many embodiments include digitally streaming the waveform data 2010, as disclosed herein, and also enjoying the benefit of needing to load the route parameter information while setting the data acquisition hardware only once. Because the waveform data 2010 is streamed to only one file, there is no need to open and close files, or switch between loading and writing operations with the storage medium. It can be shown that the collection and storage of the waveform data 2010, as described herein, can be shown to produce relatively more meaningful data in significantly less time than the traditional batch data acquisition approach. An example of this includes an electric motor about which waveform data can be collected with a data length of 4K points (i.e., 4,096) for sufficiently high resolution in order to, among other things, distinguish electrical sideband frequencies. For fans or blowers, a reduced resolution of 1K (i.e., 1,024) can be used. In certain instances, 1K can be the minimum waveform data length requirement. The sampling rate can be 1,280 Hz and that equates to an Fmax of 500 Hz. It will be appreciated in light of the disclosure that oversampling by an industry standard factor of 2.56 can satisfy the necessary two-times (2×) oversampling for the Nyquist Criterion with some additional leeway that can accommodate anti-aliasing filter-rolloff. The time to acquire this waveform data would be 1,024 points at 1,280 hertz, which are 800 milliseconds.
To improve accuracy, the waveform data can be averaged. Eight averages can be used with, for example, fifty percent overlap. This would extend the time from 800 milliseconds to 3.6 seconds, which is equal to 800 msec×8 averages×0.5 (overlap ratio)+0.5×800 msec (non-overlapped head and tail ends). After collection at Fmax=500 Hz waveform data, a higher sampling rate can be used. In one example, ten times (10×) the previous sampling rate can be used and Fmax=10 kHz. By way of this example, eight averages can be used with fifty percent (50%) overlap to collect waveform data at this higher rate that can amount to a collection time of 360 msec or 0.36 seconds. It will be appreciated in light of the disclosure that it can be necessary to read the hardware collection parameters for the higher sampling rate from the route list, as well as permit hardware auto-scaling, or the resetting of other necessary hardware collection parameters, or both. To that end, a few seconds of latency can be added to accommodate the changes in sampling rate. In other instances, introducing latency can accommodate hardware autoscaling and changes to hardware collection parameters that can be required when using the lower sampling rate disclosed herein. In addition to accommodating the change in sampling rate, additional time is needed for reading the route point information from the database (i.e., where to monitor and where to monitor next), displaying the route information, and processing the waveform data. Moreover, display of the waveform data and/or associated spectra can also consume significant time. In light of the above, 15 seconds to 20 seconds can elapse while obtaining waveform data at each measurement point.
In further examples, additional sampling rates can be added but this can make the total amount time for the vibration survey even longer because time adds up from changeover time from one sampling rate to another and from the time to obtain additional data at different sampling rate. In one example, a lower sampling rate is used, such as a sampling rate of 128 Hz where Fmax=50 Hz. By way of this example, the vibration survey would, therefore, require an additional 36 seconds for the first set of averaged data at this sampling rate, in addition to others mentioned above, and consequently the total time spent at each measurement point increases even more dramatically. Further embodiments include using similar digital streaming of gap free waveform data as disclosed herein for use with wind turbines and other machines that can have relatively slow speed rotating or oscillating systems. In many examples, the waveform data collected can include long samples of data at a relatively high-sampling rate. In one example, the sampling rate can be 100 kHz and the sampling duration can be for two minutes on all of the channels being recorded. In many examples, one channel can be for the single axis reference sensor and three more data channels can be for the tri-axial three channel sensor. It will be appreciated in light of the disclosure that the long data length can be shown to facilitate detection of extremely low frequency phenomena. The long data length can also be shown to accommodate the inherent speed variability in wind turbine operations. Additionally, the long data length can further be shown to provide the opportunity for using numerous averages such as those discussed herein, to achieve very high spectral resolution, and to make feasible tape loops for certain spectral analyses. Many multiple advanced analytical techniques can now become available because such techniques can use the available long uninterrupted length of waveform data in accordance with the present disclosure.
It will also be appreciated in light of the disclosure that the simultaneous collection of waveform data from multiple channels can facilitate performing transfer functions between multiple channels. Moreover, the simultaneous collection of waveform data from multiple channels facilitates establishing phase relationships across the machine so that more sophisticated correlations can be utilized by relying on the fact that the waveforms from each of the channels are collected simultaneously. In other examples, more channels in the data collection can be used to reduce the time it takes to complete the overall vibration survey by allowing for simultaneous acquisition of waveform data from multiple sensors that otherwise would have to be acquired, in a subsequent fashion, moving sensor to sensor in the vibration survey.
The present disclosure includes the use of at least one of the single-axis reference probe on one of the channels to allow for acquisition of relative phase comparisons between channels. The reference probe can be an accelerometer or other type of transducer that is not moved and, therefore, fixed at an unchanging location during the vibration survey of one machine. Multiple reference probes can each be deployed as at suitable locations fixed in place (i.e., at unchanging locations) throughout the acquisition of vibration data during the vibration survey. In certain examples, up to seven reference probes can be deployed depending on the capacity of the data collection module 2160 or the like. Using transfer functions or similar techniques, the relative phases of all channels may be compared with one another at all selected frequencies. By keeping the one or more reference probes fixed at their unchanging locations while moving or monitoring the other tri-axial vibration sensors, it can be shown that the entire machine can be mapped with regard to amplitude and relative phase. This can be shown to be true even when there are more measurement points than channels of data collection. With this information, an operating deflection shape can be created that can show dynamic movements of the machine in 3 D, which can provide an invaluable diagnostic tool. In embodiments, the one or more reference probes can provide relative phase, rather than absolute phase. It will be appreciated in light of the disclosure that relative phase may not be as valuable absolute phase for some purposes, but the relative phase the information can still be shown to be very useful.
In embodiments, the sampling rates used during the vibration survey can be digitally synchronized to predetermined operational frequencies that can relate to pertinent parameters of the machine such as rotating or oscillating speed. Doing this, permits extracting even more information using synchronized averaging techniques. It will be appreciated in light of the disclosure that this can be done without the use of a key phasor or a reference pulse from a rotating shaft, which is usually not available for route collected data. As such, non-synchronous signals can be removed from a complex signal without the need to deploy synchronous averaging using the key phasor. This can be shown to be very powerful when analyzing a particular pinion in a gearbox or generally applied to any component within a complicated mechanical mechanism. In many instances, the key phasor or the reference pulse is rarely available with route collected data, but the techniques disclosed herein can overcome this absence. In embodiments, there can be multiple shafts running at different speeds within the machine being analyzed. In certain instances, there can be a single-axis reference probe for each shaft. In other instances, it is possible to relate the phase of one shaft to another shaft using only one single axis reference probe on one shaft at its unchanging location. In embodiments, variable speed equipment can be more readily analyzed with relatively longer duration of data relative to single speed equipment. The vibration survey can be conducted at several machine speeds within the same contiguous set of vibration data using the same techniques disclosed herein. These techniques can also permit the study of the change of the relationship between vibration and the change of the rate of speed that was not available before.
In embodiments, there are numerous analytical techniques that can emerge from because raw waveform data can be captured in a gap-free digital format as disclosed herein. The gap-free digital format can facilitate many paths to analyze the waveform data in many ways after the fact to identify specific problems. The vibration data collected in accordance with the techniques disclosed herein can provide the analysis of transient, semi-periodic and very low frequency phenomena. The waveform data acquired in accordance with the present disclosure can contain relatively longer streams of raw gap-free waveform data that can be conveniently played back as needed, and on which many and varied sophisticated analytical techniques can be performed. A large number of such techniques can provide for various forms of filtering to extract low amplitude modulations from transient impact data that can be included in the relatively longer stream of raw gap-free waveform data. It will be appreciated in light of the disclosure that in past data collection practices, these types of phenomena were typically lost by the averaging process of the spectral processing algorithms because the goal of the previous data acquisition module was purely periodic signals; or these phenomena were lost to file size reduction methodologies due to the fact that much of the content from an original raw signal was typically discarded knowing it would not be used.
In embodiments, there is a method of monitoring vibration of a machine having at least one shaft supported by a set of bearings. The method includes monitoring a first data channel assigned to a single-axis sensor at an unchanging location associated with the machine. The method also includes monitoring a second, third, and fourth data channel assigned to a three-axis sensor. The method further includes recording gap-free digital waveform data simultaneously from all of the data channels while the machine is in operation; and determining a change in relative phase based on the digital waveform data. The method also includes the tri-axial sensor being located at a plurality of positions associated with the machine while obtaining the digital waveform. In embodiments, the second, third, and fourth channels are assigned together to a sequence of tri-axial sensors each located at different positions associated with the machine. In embodiments, the data is received from all of the sensors on all of their channels simultaneously.
The method also includes determining an operating deflection shape based on the change in relative phase information and the waveform data. In embodiments, the unchanging location of the reference sensor is a position associated with a shaft of the machine. In embodiments, the tri-axial sensors in the sequence of the tri-axial sensors are each located at different positions and are each associated with different bearings in the machine. In embodiments, the unchanging location is a position associated with a shaft of the machine and, wherein, the tri-axial sensors in the sequence of the tri-axial sensors are each located at different positions and are each associated with different bearings that support the shaft in the machine. The various embodiments include methods of sequentially monitoring vibration or similar process parameters and signals of a rotating or oscillating machine or analogous process machinery from a number of channels simultaneously, which can be known as an ensemble. In various examples, the ensemble can include one to eight channels. In further examples, an ensemble can represent a logical measurement grouping on the equipment being monitored whether those measurement locations are temporary for measurement, supplied by the original equipment manufacturer, retrofit at a later date, or one or more combinations thereof.
In one example, an ensemble can monitor bearing vibration in a single direction. In a further example, an ensemble can monitor three different directions (e.g., orthogonal directions) using a tri-axial sensor. In yet further examples, an ensemble can monitor four or more channels where the first channel can monitor a single axis vibration sensor, and the second, the third, and the fourth channels can monitor each of the three directions of the tri-axial sensor. In other examples, the ensemble can be fixed to a group of adjacent bearings on the same piece of equipment or an associated shaft. The various embodiments provide methods that include strategies for collecting waveform data from various ensembles deployed in vibration studies or the like in a relatively more efficient manner. The methods also include simultaneously monitoring of a reference channel assigned to an unchanging reference location associated with the ensemble monitoring the machine. The cooperation with the reference channel can be shown to support a more complete correlation of the collected waveforms from the ensembles. The reference sensor on the reference channel can be a single axis vibration sensor, or a phase reference sensor that can be triggered by a reference location on a rotating shaft or the like. As disclosed herein, the methods can further include recording gap-free digital waveform data simultaneously from all of the channels of each ensemble at a relatively high rate of sampling so as to include all frequencies deemed necessary for the proper analysis of the machinery being monitored while it is in operation. The data from the ensembles can be streamed gap-free to a storage medium for subsequent processing that can be connected to a cloud network facility, a local data link, Bluetooth™ connectivity, cellular data connectivity, or the like.
In embodiments, the methods disclosed herein include strategies for collecting data from the various ensembles including digital signal processing techniques that can be subsequently applied to data from the ensembles to emphasize or better isolate specific frequencies or waveform phenomena. This can be in contrast with current methods that collect multiple sets of data at different sampling rates, or with different hardware filtering configurations including integration, that provide relatively less post-processing flexibility because of the commitment to these same (known as a priori hardware configurations). These same hardware configurations can also be shown to increase time of the vibration survey due to the latency delays associated with configuring the hardware for each independent test. In embodiments, the methods for collecting data from various ensembles include data marker technology that can be used for classifying sections of streamed data as homogenous and belonging to a specific ensemble. In one example, a classification can be defined as operating speed. In doing so, a multitude of ensembles can be created from what conventional systems would collect as only one. The many embodiments include post-processing analytic techniques for comparing the relative phases of all the frequencies of interest not only between each channel of the collected ensemble but also between all of the channels of all of the ensembles being monitored, when applicable.

The machine 2400 can also have tri-axial (e.g., orthogonal axes) sensors 2480, such as a tri-axial sensor 2482, a tri-axial sensor 2484, and more as needed. In many examples, the tri-axial sensors 2480 can be positioned in the machine 2400 at locations that allow for the sensing of one of each of the bearing packs in the sets of bearings 2420 that is associated with the rotating or oscillating components of the machine 2400. The machine 2400 can also have temperature sensors 2500, such as a temperature sensor 2502, a temperature sensor 2504, and more as needed. The machine 2400 can also have a tachometer sensor 2510 or more as needed that each detail the RPMs of one of its rotating components. By way of the above example, the first sensor ensemble 2450 can survey the above sensors associated with the first machine 2400. To that end, the first ensemble 2450 can be configured to receive eight channels. In other examples, the first sensor ensemble 2450 can be configured to have more than eight channels, or less than eight channels as needed. In this example, the eight channels include two channels that can each monitor a single-axis reference sensor signal and three channels that can monitor a tri-axial sensor signal. The remaining three channels can monitor two temperature signals and a signal from a tachometer. In one example, the first ensemble 2450 can monitor the single-axis sensor 2462, the single-axis sensor 2464, the tri-axial sensor 2482, the temperature sensor 2502, the temperature sensor 2504, and the tachometer sensor 2510 in accordance with the present disclosure. During a vibration survey on the machine 2400, the first ensemble 2450 can first monitor the tri-axial sensor 2482 and then move next to the tri-axial sensor 2484.
After monitoring the tri-axial sensor 2484, the first ensemble 2450 can monitor additional tri-axial sensors on the machine 2400 as needed and that are part of the predetermined route list associated with the vibration survey of the machine 2400, in accordance with the present disclosure. During this vibration survey, the first ensemble 2450 can continually monitor the single-axis sensor 2462, the single-axis sensor 2464, the two temperature sensors 2502, 2504, and the tachometer sensor 2510 while the first ensemble 2450 can serially monitor the multiple tri-axial sensors 2480 in the pre-determined route plan for this vibration survey.

The machine 2600 can also have tri-axial (e.g., orthogonal axes) sensors 2680, such as a tri-axial sensor 2682, a tri-axial sensor 2684, a tri-axial sensor 2686, a tri-axial sensor 2688, and more as needed. In many examples, the tri-axial sensors 2680 can be positioned in the machine 2600 at locations that allow for the sensing of one of each of the bearing packs in the sets of bearings 2620 that is associated with the rotating or oscillating components of the machine 2600. The machine 2600 can also have temperature sensors 2700, such as a temperature sensor 2702, a temperature sensor 2704, and more as needed. The machine 2600 can also have a tachometer sensor 2710 or more as needed that each detail the RPMs of one of its rotating components.
By way of the above example, the second sensor ensemble 2650 can survey the above sensors associated with the second machine 2600. To that end, the second ensemble 2650 can be configured to receive eight channels. In other examples, the second sensor ensemble 2650 can be configured to have more than eight channels or less than eight channels as needed. In this example, the eight channels include one channel that can monitor a single-axis reference sensor signal and six channels that can monitor two tri-axial sensor signals. The remaining channel can monitor a temperature signal. In one example, the second ensemble 2650 can monitor the single axis sensor 2662, the tri-axial sensor 2682, the tri-axial sensor 2684, and the temperature sensor 2702. During a vibration survey on the machine 2600 in accordance with the present disclosure, the second ensemble 2650 can first monitor the tri-axial sensor 2682 simultaneously with the tri-axial sensor 2684 and then move onto the tri-axial sensor 2686 simultaneously with the tri-axial sensor 2688.
After monitoring the tri-axial sensors 2680, the second ensemble 2650 can monitor additional tri-axial sensors (in simultaneous pairs) on the machine 2600 as needed and that are part of the predetermined route list associated with the vibration survey of the machine 2600 in accordance with the present disclosure. During this vibration survey, the second ensemble 2650 can continually monitor the single-axis sensor 2662 at its unchanging location and the temperature sensor 2702 while the second ensemble 2650 can serially monitor the multiple tri-axial sensors in the pre-determined route plan for this vibration survey.

The many embodiments also include a fourth machine 2950 having rotating or oscillating components 2960, or both, each supported by a set of bearings 2970 including a bearing pack 2972, a bearing pack 2974, a bearing pack 2976, and more as needed. The fourth machine 2950 can be also monitored by the third sensor ensemble 2850 when the user moves it to the fourth machine 2950. The many embodiments also include a fifth machine 3000 having rotating or oscillating components 3010, or both. The fifth machine 3000 may not be explicitly monitored by any sensor or any sensor ensembles in operation but it can create vibrations or other impulse energy of sufficient magnitude to be recorded in the data associated with any one of the machines 2400, 2600, 2800, 2950 under a vibration survey.
The many embodiments include monitoring the first sensor ensemble 2450 on the first machine 2400 through the predetermined route as disclosed herein. The many embodiments also include monitoring the second sensor ensemble 2650 on the second machine 2600 through the predetermined route. The locations of machine 2400 being close to machine 2600 can be included in the contextual metadata of both vibration surveys. The third ensemble 2850 can be moved between machine 2800, machine 2950, and other suitable machines. The machine 3000 has no sensors onboard as configured, but could be monitored as needed by the third sensor ensemble 2850. The machine 3000 and its operational characteristics can be recorded in the metadata in relation to the vibration surveys on the other machines to note its contribution due to its proximity.
The many embodiments include hybrid database adaptation for harmonizing relational metadata and streaming raw data formats. Unlike older systems that utilized traditional database structure for associating nameplate and operational parameters (sometimes deemed metadata) with individual data measurements that are discrete and relatively simple, it will be appreciated in light of the disclosure that more modern systems can collect relatively larger quantities of raw streaming data with higher sampling rates and greater resolutions. At the same time, it will also be appreciated in light of the disclosure that the network of metadata with which to link and obtain this raw data or correlate with this raw data, or both, is expanding at ever-increasing rates.
In one example, a single overall vibration level can be collected as part of a route or prescribed list of measurement points. This data collected can then be associated with database measurement location information for a point located on a surface of a bearing housing on a specific piece of the machine adjacent to a coupling in a vertical direction. Machinery analysis parameters relevant to the proper analysis can be associated with the point located on the surface. Examples of machinery analysis parameters relevant to the proper analysis can include a running speed of a shaft passing through the measurement point on the surface. Further examples of machinery analysis parameters relevant to the proper analysis can include one of, or a combination of: running speeds of all component shafts for that piece of equipment and/or machine, bearing types being analyzed such as sleeve or rolling element bearings, the number of gear teeth on gears should there be a gearbox, the number of poles in a motor, slip and line frequency of a motor, roller bearing element dimensions, number of fan blades, or the like. Examples of machinery analysis parameters relevant to the proper analysis can further include machine operating conditions such as the load on the machines and whether load is expressed in percentage, wattage, air flow, head pressure, horsepower, and the like. Further examples of machinery analysis parameters include information relevant to adjacent machines that might influence the data obtained during the vibration study.
It will be appreciated in light of the disclosure that the vast array of equipment and machinery types can support many different classifications, each of which can be analyzed in distinctly different ways. For example, some machines, like screw compressors and hammer mills, can be shown to run much noisier and can be expected to vibrate significantly more than other machines. Machines known to vibrate more significantly can be shown to require a change in vibration levels that can be considered acceptable relative to quieter machines.
The present disclosure further includes hierarchical relationships found in the vibrational data collected that can be used to support proper analysis of the data. One example of the hierarchical data includes the interconnection of mechanical componentry such as a bearing being measured in a vibration survey and the relationship between that bearing, including how that bearing connects to a particular shaft on which is mounted a specific pinion within a particular gearbox, and the relationship between the shaft, the pinion, and the gearbox. The hierarchical data can further include in what particular spot within a machinery gear train that the bearing being monitored is located relative to other components in the machine. The hierarchical data can also detail whether the bearing being measured in a machine is in close proximity to another machine whose vibrations may affect what is being measured in the machine that is the subject of the vibration study.
The analysis of the vibration data from the bearing or other components related to one another in the hierarchical data can use table lookups, searches for correlations between frequency patterns derived from the raw data, and specific frequencies from the metadata of the machine. In some embodiments, the above can be stored in and retrieved from a relational database. In embodiments, National Instrument's Technical Data Management Solution (TDMS) file format can be used. The TDMS file format can be optimized for streaming various types of measurement data (i.e., binary digital samples of waveforms), as well as also being able to handle hierarchical metadata.
The many embodiments include a hybrid relational metadata—binary storage approach (HRM-BSA). The HRM-BSA can include a structured query language (SQL) based relational database engine. The structured query language based relational database engine can also include a raw data engine that can be optimized for throughput and storage density for data that is flat and relatively structureless. It will be appreciated in light of the disclosure that benefits can be shown in the cooperation between the hierarchical metadata and the SQL relational database engine. In one example, marker technologies and pointer sign-posts can be used to make correlations between the raw database engine and the SQL relational database engine. Three examples of correlations between the raw database engine and the SQL relational database engine linkages include: (1) pointers from the SQL database to the raw data; (2) pointers from the ancillary metadata tables or similar grouping of the raw data to the SQL database; and (3) independent storage tables outside the domain of either the SQL database or raw data technologies.
With reference to
The present disclosure can include markers that can be applied to a time mark or a sample length within the raw waveform data. The markers generally fall into two categories: preset or dynamic. The preset markers can correlate to preset or existing operating conditions (e.g., load, head pressure, air flow cubic feet per minute, ambient temperature, RPMs, and the like.). These preset markers can be fed into the data acquisition system directly. In certain instances, the preset markers can be collected on data channels in parallel with the waveform data (e.g., waveforms for vibration, current, voltage, etc.). Alternatively, the values for the preset markers can be entered manually.
For dynamic markers such as trending data, it can be important to compare similar data like comparing vibration amplitudes and patterns with a repeatable set of operating parameters. One example of the present disclosure includes one of the parallel channel inputs being a key phasor trigger pulse from an operating shaft that can provide RPM information at the instantaneous time of collection. In this example of dynamic markers, sections of collected waveform data can be marked with appropriate speeds or speed ranges.
The present disclosure can also include dynamic markers that can correlate to data that can be derived from post processing and analytics performed on the sample waveform. In further embodiments, the dynamic markers can also correlate to post-collection derived parameters including RPMs, as well as other operationally derived metrics such as alarm conditions like a maximum RPM. In certain examples, many modern pieces of equipment that are candidates for a vibration survey with the portable data collection systems described herein do not include tachometer information. This can be true because it is not always practical or cost-justifiable to add a tachometer even though the measurement of RPM can be of primary importance for the vibration survey and analysis. It will be appreciated that for fixed speed machinery obtaining an accurate RPM measurement can be less important especially when the approximate speed of the machine can be ascertained before-hand; however, variable-speed drives are becoming more and more prevalent. It will also be appreciated in light of the disclosure that various signal processing techniques can permit the derivation of RPM from the raw data without the need for a dedicated tachometer signal.
In many embodiments, the RPM information can be used to mark segments of the raw waveform data over its collection history. Further embodiments include techniques for collecting instrument data following a prescribed route of a vibration study. The dynamic markers can enable analysis and trending software to utilize multiple segments of the collection interval indicated by the markers (e.g., two minutes) as multiple historical collection ensembles, rather than just one as done in previous systems where route collection systems would historically store data for only one RPM setting. This could, in turn, be extended to any other operational parameter such as load setting, ambient temperature, and the like, as previously described. The dynamic markers, however, that can be placed in a type of index file pointing to the raw data stream can classify portions of the stream in homogenous entities that can be more readily compared to previously collected portions of the raw data stream
The many embodiments include the hybrid relational metadata-binary storage approach that can use the best of pre-existing technologies for both relational and raw data streams. In embodiments, the hybrid relational metadata—binary storage approach can marry them together with a variety of marker linkages. The marker linkages can permit rapid searches through the relational metadata and can allow for more efficient analyses of the raw data using conventional SQL techniques with pre-existing technology. This can be shown to permit utilization of many of the capabilities, linkages, compatibilities, and extensions that conventional database technologies do not provide.
The marker linkages can also permit rapid and efficient storage of the raw data using conventional binary storage and data compression techniques. This can be shown to permit utilization of many of the capabilities, linkages, compatibilities, and extensions that conventional raw data technologies provide such as TMDS (National Instruments), UFF (Universal File Format such as UFF58), and the like. The marker linkages can further permit using the marker technology links where a vastly richer set of data from the ensembles can be amassed in the same collection time as more conventional systems. The richer set of data from the ensembles can store data snapshots associated with predetermined collection criterion and the proposed system can derive multiple snapshots from the collected data streams utilizing the marker technology. In doing so, it can be shown that a relatively richer analysis of the collected data can be achieved. One such benefit can include more trending points of vibration at a specific frequency or order of running speed versus RPM, load, operating temperature, flow rates, and the like, which can be collected for a similar time relative to what is spent collecting data with a conventional system.
In embodiments, the platform 100 may include the local data collection system 102 deployed in the environment 104 to monitor signals from machines, elements of the machines and the environment of the machines including heavy duty machines deployed at a local job site or at distributed job sites under common control. The heavy-duty machines may include earthmoving equipment, heavy duty on-road industrial vehicles, heavy duty off-road industrial vehicles, industrial machines deployed in various settings such as turbines, turbomachinery, generators, pumps, pulley systems, manifold and valve systems, and the like. In embodiments, heavy industrial machinery may also include earth-moving equipment, earth-compacting equipment, hauling equipment, hoisting equipment, conveying equipment, aggregate production equipment, equipment used in concrete construction, and piledriving equipment. In examples, earth moving equipment may include excavators, backhoes, loaders, bulldozers, skid steer loaders, trenchers, motor graders, motor scrapers, crawler loaders, and wheeled loading shovels. In examples, construction vehicles may include dumpers, tankers, tippers, and trailers. In examples, material handling equipment may include cranes, conveyors, forklift, and hoists. In examples, construction equipment may include tunnel and handling equipment, road rollers, concrete mixers, hot mix plants, road making machines (compactors), stone crashers, pavers, slurry seal machines, spraying and plastering machines, and heavy-duty pumps. Further examples of heavy industrial equipment may include different systems such as implement traction, structure, power train, control, and information. Heavy industrial equipment may include many different powertrains and combinations thereof to provide power for locomotion and to also provide power to accessories and onboard functionality. In each of these examples, the platform 100 may deploy the local data collection system 102 into the environment 104 in which these machines, motors, pumps, and the like, operate and directly connected integrated into each of the machines, motors, pumps, and the like.
In embodiments, the platform 100 may include the local data collection system 102 deployed in the environment 104 to monitor signals from machines in operation and machines in being constructed such as turbine and generator sets like Siemens™ SGT6-5000F™ gas turbine, an SST-900™ steam turbine, an SGen6-1000 ATM generator, and an SGen6-100 ATM generator, and the like. In embodiments, the local data collection system 102 may be deployed to monitor steam turbines as they rotate in the currents caused by hot water vapor that may be directed through the turbine but otherwise generated from a different source such as from gas-fired burners, nuclear cores, molten salt loops and the like. In these systems, the local data collection system 102 may monitor the turbines and the water or other fluids in a closed loop cycle in which water condenses and is then heated until it evaporates again. The local data collection system 102 may monitor the steam turbines separately from the fuel source deployed to heat the water to steam. In examples, working temperatures of steam turbines may be between 500 and 650° C. In many embodiments, an array of steam turbines may be arranged and configured for high, medium, and low pressure, so they may optimally convert the respective steam pressure into rotational movement.
The local data collection system 102 may also be deployed in a gas turbines arrangement and therefore not only monitor the turbine in operation but also monitor the hot combustion gases feed into the turbine that may be in excess of 1,500° C. Because these gases are much hotter than those in steam turbines, the blades may be cooled with air that may flow out of small openings to create a protective film or boundary layer between the exhaust gases and the blades. This temperature profile may be monitored by the local data collection system 102. Gas turbine engines, unlike typical steam turbines, include a compressor, a combustion chamber, and a turbine all of which are journaled for rotation with a rotating shaft. The construction and operation of each of these components may be monitored by the local data collection system 102.
In embodiments, the platform 100 may include the local data collection system 102 deployed in the environment 104 to monitor signals from water turbines serving as rotary engines that may harvest energy from moving water and are used for electric power generation. The type of water turbine or hydro-power selected for a project may be based on the height of standing water, often referred to as head, and the flow (or volume of water) at the site. In this example, a generator may be placed at the top of a shaft that connects to the water turbine. As the turbine catches the naturally moving water in its blade and rotates, the turbine sends rotational power to the generator to generate electrical energy. In doing so, the platform 100 may monitor signals from the generators, the turbines, the local water system, flow controls such as dam windows and sluices. Moreover, the platform 100 may monitor local conditions on the electric grid including load, predicted demand, frequency response, and the like, and include such information in the monitoring and control deployed by platform 100 in these hydroelectric settings.

Operation faults, maintenance indicators, and interactions from other machines may cause maintenance or operational issues may occur during operation, during installation, and during maintenance. The faults may occur in the mechanisms of the industrial machines but may also occur in infrastructure that supports the machine such as its wiring and local installation platforms. In embodiments, the large industrial machines may face different types of fault conditions such as overheating, noise, grinding gears, excessive vibration of machine parts, fan vibration problems, problems with large industrial machines rotating parts.
In embodiments, the platform 100 may include the local data collection system 102 deployed in the environment 104 to monitor signals from industrial machinery including failures that may be caused by premature bearing failure that may occur due to contamination or loss of bearing lubricant. In another example, a mechanical defect such as misalignment of bearings may occur. Many factors may contribute to the failure such as metal fatigue, therefore, the local data collection system 102 may monitor cycles and local stresses. By way of this example, the platform 100 may monitor the incorrect operation of machine parts, lack of maintenance and servicing of parts, corrosion of vital machine parts, such as couplings or gearboxes, misalignment of machine parts, and the like. Though the fault occurrences cannot be completely stopped, many industrial breakdowns may be mitigated to reduce operational and financial losses. The platform 100 provides real-time monitoring and predictive maintenance in many industrial environments wherein it has been shown to present a cost-savings over regularly-scheduled maintenance processes that replace parts according to a rigid expiration of time and not actual load and wear and tear on the element or machine.

In examples, signal processing may be performed using a plurality of techniques, including but not limited to transformations, spectral estimations, statistical operations, probabilistic and stochastic operations, numerical theory analysis, data mining, and the like. The processing of various types of signals forms the basis of many electrical or computational process. As a result, signal processing applies to almost all disciplines and applications in the industrial environment such as audio and video processing, image processing, wireless communications, process control, industrial automation, financial systems, feature extraction, quality improvements such as noise reduction, image enhancement, and the like. Signal processing for images may include pattern recognition for manufacturing inspections, quality inspection, and automated operational inspection and maintenance. The platform 100 may employ many pattern recognition techniques including those that may classify input data into classes based on key features with the objective of recognizing patterns or regularities in data. The platform 100 may also implement pattern recognition processes with machine learning operations and may be used in applications such as computer vision, speech and text processing, radar processing, handwriting recognition, CAD systems, and the like. The platform 100 may employ supervised classification and unsupervised classification. The supervised learning classification algorithms may be based to create classifiers for image or pattern recognition, based on training data obtained from different object classes.

In embodiments, the platform 100 may include the local data collection system 102 deployed in the environment 104 using machine learning to enable derivation-based learning outcomes from computers without the need to program them. The platform 100 may, therefore, learn from and make decisions on a set of data, by making data-driven predictions and adapting according to the set of data. In embodiments, machine learning may involve performing a plurality of machine learning tasks by machine learning systems, such as supervised learning, unsupervised learning, and reinforcement learning.

In examples, the tasks may also be classified as machine learning problems such as classification, regression, clustering, density estimation, dimensionality reduction, anomaly detection, and the like. In examples, machine learning may include a plurality of mathematical and statistical techniques. In examples, the many types of machine learning algorithms may include decision tree based learning, association rule learning, deep learning, artificial neural networks, genetic learning algorithms, inductive logic programming, support vector machines (SVMs), Bayesian network, reinforcement learning, representation learning, rule-based machine learning, sparse dictionary learning, similarity and metric learning, learning classifier systems (LCS), logistic regression, random forest, K-Means, gradient boost and adaboost, K-nearest neighbors (KNN), a priori algorithms, and the like.

By way of this example, genetic algorithms may be deployed to solve a variety of optimization problems that are not well suited for standard optimization algorithms, including problems in which the objective functions are discontinuous, not differentiable, stochastic, or highly nonlinear. In an example, the genetic algorithm may be used to address problems of mixed integer programming, where some components restricted to being integer-valued. Genetic algorithms and machine learning techniques and systems may be used in computational intelligence systems, computer vision, Natural Language Processing (NLP), recommender systems, reinforcement learning, building graphical models, and the like.

Additional details are provided below in connection with the methods, systems, devices, and components depicted in connection with
Combination of inputs (including selection of what sensors or input sources to turn “on” or “off”) may be performed under the control of machine-based intelligence, such as using a local cognitive input selection system 4004, an optionally remote cognitive input selection system 4114, or a combination of the two. The cognitive input selection systems 4004, 4014 may use intelligence and machine learning capabilities described elsewhere in this disclosure, such as using detected conditions (such as conditions informed by the input sources 116 or sensors), state information (including state information determined by a machine state recognition system 4020 that may determine a state), such as relating to an operational state, an environmental state, a state within a known process or workflow, a state involving a fault or diagnostic condition, or many others. This may include optimization of input selection and configuration based on learning feedback from the learning feedback system 4012, which may include providing training data (such as from the host processing system 112 or from other data collection systems 102 either directly or from the host 112) and may include providing feedback metrics, such as success metrics calculated within the analytic system 4018 of the host processing system 112. For example, if a data stream consisting of a particular combination of sensors and inputs yields positive results in a given set of conditions (such as providing improved pattern recognition, improved prediction, improved diagnosis, improved yield, improved return on investment, improved efficiency, or the like), then metrics relating to such results from the analytic system 4018 can be provided via the learning feedback system 4012 to the cognitive input selection systems 4004, 4014 to help configure future data collection to select that combination in those conditions (allowing other input sources to be de-selected, such as by powering down the other sensors). In embodiments, selection and de-selection of sensor combinations, under control of one or more of the cognitive input selection systems 4004, may occur with automated variation, such as using genetic programming techniques, based on learning feedback 4012, such as from the analytic system 4018, effective combinations for a given state or set of conditions are promoted, and less effective combinations are demoted, resulting in progressive optimization and adaptation of the local data collection system to each unique environment. Thus, an automatically adapting, multi-sensor data collection system is provided, where cognitive input selection is used (with feedback) to improve the effectiveness, efficiency, or other performance parameters of the data collection system within its particular environment. Performance parameters may relate to overall system metrics (such as financial yields, process optimization results, energy production or usage, and the like), analytic metrics (such as success in recognizing patterns, making predictions, classifying data, or the like), and local system metrics (such as bandwidth utilization, storage utilization, power consumption, and the like). In embodiments, the analytic system 4018, the state system 4020 and the cognitive input selection system 4114 of a host may take data from multiple data collection systems 102, such that optimization (including of input selection) may be undertaken through coordinated operation of multiple systems 102. For example, the cognitive input selection system 4114 may understand that if one data collection system 102 is already collecting vibration data for an X-axis, the X-axis vibration sensor for the other data collection system might be turned off, in favor of getting Y-axis data from the other data collector 102. Thus, through coordinated collection by the host cognitive input selection system 4114, the activity of multiple collectors 102, across a host of different sensors, can provide for a rich data set for the host processing system 112, without wasting energy, bandwidth, storage space, or the like. As noted above, optimization may be based on overall system success metrics, analytic success metrics, and local system metrics, or a combination of the above.
Methods and systems are disclosed herein for cloud-based, machine pattern analysis of state information from multiple industrial sensors to provide anticipated state information for an industrial system. In embodiments, machine learning may take advantage of a state machine, such as tracking states of multiple analog and/or digital sensors, feeding the states into a pattern analysis facility, and determining anticipated states of the industrial system based on historical data about sequences of state information. For example, where a temperature state of an industrial machine exceeds a certain threshold and is followed by a fault condition, such as breaking down of a set of bearings, that temperature state may be tracked by a pattern recognizer, which may produce an output data structure indicating an anticipated bearing fault state (whenever an input state of a high temperature is recognized). A wide range of measurement values and anticipated states may be managed by a state machine, relating to temperature, pressure, vibration, acceleration, momentum, inertia, friction, heat, heat flux, galvanic states, magnetic field states, electrical field states, capacitance states, charge and discharge states, motion, position, and many others. States may comprise combined states, where a data structure includes a series of states, each of which is represented by a place in a byte-like data structure. For example, an industrial machine may be characterized by a genetic structure, such as one that provides pressure, temperature, vibration, and acoustic data, the measurement of which takes one place in the data structure, so that the combined state can be operated on as a byte-like structure, such as a structure for compactly characterizing the current combined state of the machine or environment, or compactly characterizing the anticipated state. This byte-like structure can be used by a state machine for machine learning, such as pattern recognition that operates on the structure to determine patterns that reflect combined effects of multiple conditions. A wide variety of such structure can be tracked and used, such as in machine learning, representing various combinations, of various length, of the different elements that can be sensed in an industrial environment. In embodiments, byte-like structures can be used in a genetic programming technique, such as by substituting different types of data, or data from varying sources, and tracking outcomes over time, so that one or more favorable structures emerges based on the success of those structures when used in real world situations, such as indicating successful predictions of anticipated states, or achievement of success operational outcomes, such as increased efficiency, successful routing of information, achieving increased profits, or the like. That is, by varying what data types and sources are used in byte-like structures that are used for machine optimization over time, a genetic programming-based machine learning facility can “evolve” a set of data structures, consisting of a favorable mix of data types (e.g., pressure, temperature, and vibration), from a favorable mix of data sources (e.g., temperature is derived from sensor X, while vibration comes from sensor Y), for a given purpose. Different desired outcomes may result in different data structures that are best adapted to support effective achievement of those outcomes over time with application of machine learning and promotion of structures with favorable results for the desired outcome in question by genetic programming. The promoted data structures may provide compact, efficient data for various activities as described throughout this disclosure, including being stored in data pools (which may be optimized by storing favorable data structures that provide the best operational results for a given environment), being presented in data marketplaces (such as being presented as the most effective structures for a given purpose), and the like.
In embodiments, a platform is provided having cloud-based, machine pattern analysis of state information from multiple analog industrial sensors to provide anticipated state information for an industrial system. In embodiments, the host processing system 112, such as disposed in the cloud, may include the state system 4020, which may be used to infer or calculate a current state or to determine an anticipated future state relating to the data collection system 102 or some aspect of the environment in which the data collection system 102 is disposed, such as the state of a machine, a component, a workflow, a process, an event (e.g., whether the event has occurred), an object, a person, a condition, a function, or the like Maintaining state information allows the host processing system 112 to undertake analysis, such as in one or more analytic systems 4018, to determine contextual information, to apply semantic and conditional logic, and perform many other functions as enabled by the processing architecture 4024 described throughout this disclosure.
In embodiments, a platform is provided having cloud-based policy automation engine for IoT, with creation, deployment, and management of IoT devices. In embodiments, the platform 100 includes (or is integrated with, or included in) the host processing system 112, such as on a cloud platform, a policy automation engine 4032 for automating creation, deployment, and management of policies to IoT devices. Polices, which may include access policies, network usage policies, storage usage policies, bandwidth usage policies, device connection policies, security policies, rule-based policies, role-based polices, and others, may be required to govern the use of IoT devices. For example, as IoT devices may have many different network and data communications to other devices, policies may be needed to indicate to what devices a given device can connect, what data can be passed on, and what data can be received. As billions of devices with countless potential connections are expected to be deployed in the near future, it becomes impossible for humans to configure policies for IoT devices on a connection-by-connection basis. Accordingly, an intelligent policy automation engine 4032 may include cognitive features for creating, configuring, and managing policies. The policy automation engine 4032 may consume information about possible policies, such as from a policy database or library, which may include one or more public sources of available policies. These may be written in one or more conventional policy languages or scripts. The policy automation engine 4032 may apply the policies according to one or more models, such as based on the characteristics of a given device, machine, or environment. For example, a large machine, such as a machine for power generation, may include a policy that only a verifiably local controller can change certain parameters of the power generation, thereby avoiding a remote “takeover” by a hacker. This may be accomplished in turn by automatically finding and applying security policies that bar connection of the control infrastructure of the machine to the Internet, by requiring access authentication, or the like. The policy automation engine 4032 may include cognitive features, such as varying the application of policies, the configuration of policies, and the like (such as features based on state information from the state system 4020). The policy automation engine 4032 may take feedback, as from the learning feedback system 4012, such as based on one or more analytic results from the analytic system 4018, such as based on overall system results (such as the extent of security breaches, policy violations, and the like), local results, and analytic results. By variation and selection based on such feedback, the policy automation engine 4032 can, over time, learn to automatically create, deploy, configure, and manage policies across very large numbers of devices, such as managing policies for configuration of connections among IoT devices.
Methods and systems are disclosed herein for on-device sensor fusion and data storage for industrial IoT devices, including on-device sensor fusion and data storage for an industrial IoT device, where data from multiple sensors is multiplexed at the device for storage of a fused data stream. For example, pressure and temperature data may be multiplexed into a data stream that combines pressure and temperature in a time series, such as in a byte-like structure (where time, pressure, and temperature are bytes in a data structure, so that pressure and temperature remain linked in time, without requiring separate processing of the streams by outside systems), or by adding, dividing, multiplying, subtracting, or the like, such that the fused data can be stored on the device. Any of the sensor data types described throughout this disclosure can be fused in this manner and stored in a local data pool, in storage, or on an IoT device, such as a data collector, a component of a machine, or the like.
In embodiments, a platform is provided having on-device sensor fusion and data storage for industrial IoT devices. In embodiments, a cognitive system is used for a self-organizing storage system 4028 for the data collection system 102. Sensor data, and in particular analog sensor data, can consume large amounts of storage capacity, in particular where a data collector 102 has multiple sensor inputs onboard or from the local environment. Simply storing all the data indefinitely is not typically a favorable option, and even transmitting all of the data may strain bandwidth limitations, exceed bandwidth permissions (such as exceeding cellular data plan capacity), or the like. Accordingly, storage strategies are needed. These typically include capturing only portions of the data (such as snapshots), storing data for limited time periods, storing portions of the data (such as intermediate or abstracted forms), and the like. With many possible selections among these and other options, determining the correct storage strategy may be highly complex. In embodiments, the self-organizing storage system 4028 may use a cognitive system, based on learning feedback 4012, and use various metrics from the analytic system 4018 or other system of the host cognitive input selection system 4114, such as overall system metrics, analytic metrics, and local performance indicators. The self-organizing storage system 4028 may automatically vary storage parameters, such as storage locations (including local storage on the data collection system 102, storage on nearby data collection systems 102 (such as using peer-to-peer organization) and remote storage, such as network-based storage), storage amounts, storage duration, type of data stored (including individual sensors or input sources 116, as well as various combined or multiplexed data, such as selected under the cognitive input selection systems 4004, 4014), storage type (such as using RAM, Flash, or other short-term memory versus available hard drive space), storage organization (such as in raw form, in hierarchies, and the like), and others. Variation of the parameters may be undertaken with feedback, so that over time the data collection system 102 adapts its storage of data to optimize itself to the conditions of its environment, such as a particular industrial environment, in a way that results in its storing the data that is needed in the right amounts and of the right type for availability to users.
In embodiments, the local cognitive input selection system 4004 may organize fusion of data for various onboard sensors, external sensors (such as in the local environment) and other input sources 116 to the local collection system 102 into one or more fused data streams, such as using the multiplexer 4002 to create various signals that represent combinations, permutations, mixes, layers, abstractions, data-metadata combinations, and the like of the source analog and/or digital data that is handled by the data collection system 102. The selection of a particular fusion of sensors may be determined locally by the cognitive input selection system 4004, such as based on learning feedback from the learning feedback system 4012, such as various overall system, analytic system and local system results and metrics. In embodiments, the system may learn to fuse particular combinations and permutations of sensors, such as in order to best achieve correct anticipation of state, as indicated by feedback of the analytic system 4018 regarding its ability to predict future states, such as the various states handled by the state system 4020. For example, the input selection system 4004 may indicate selection of a sub-set of sensors among a larger set of available sensors, and the inputs from the selected sensors may be combined, such as by placing input from each of them into a byte of a defined, multi-bit data structure (such as a combination by taking a signal from each at a given sampling rate or time and placing the result into the byte structure, then collecting and processing the bytes over time), by multiplexing in the multiplexer 4002, such as a combination by additive mixing of continuous signals, and the like. Any of a wide range of signal processing and data processing techniques for combination and fusing may be used, including convolutional techniques, coercion techniques, transformation techniques, and the like. The particular fusion in question may be adapted to a given situation by cognitive learning, such as by having the cognitive input selection system 4004 learn, based on feedback 4012 from results (such as feedback conveyed by the analytic system 4018), such that the local data collection system 102 executes context-adaptive sensor fusion.
In embodiments, the analytic system 4018 may apply to any of a wide range of analytic techniques, including statistical and econometric techniques (such as linear regression analysis, use similarity matrices, heat map based techniques, and the like), reasoning techniques (such as Bayesian reasoning, rule-based reasoning, inductive reasoning, and the like), iterative techniques (such as feedback, recursion, feed-forward and other techniques), signal processing techniques (such as Fourier and other transforms), pattern recognition techniques (such as Kalman and other filtering techniques), search techniques, probabilistic techniques (such as random walks, random forest algorithms, and the like), simulation techniques (such as random walks, random forest algorithms, linear optimization and the like), and others. This may include computation of various statistics or measures. In embodiments, the analytic system 4018 may be disposed, at least in part, on a data collection system 102, such that a local analytic system can calculate one or more measures, such as measures relating to any of the items noted throughout this disclosure. For example, measures of efficiency, power utilization, storage utilization, redundancy, entropy, and other factors may be calculated onboard, so that the data collection 102 can enable various cognitive and learning functions noted throughout this disclosure without dependence on a remote (e.g., cloud-based) analytic system.
In embodiments, the host processing system 112, a data collection system 102, or both, may include, connect to, or integrate with, a self-organizing networking system 4020, which may comprise a cognitive system for providing machine-based, intelligent or organization of network utilization for transport of data in a data collection system, such as for handling analog and other sensor data, or other source data, such as among one or more local data collection systems 102 and a host system 112. This may include organizing network utilization for source data delivered to data collection systems, for feedback data, such as analytic data provided to or via a learning feedback system 4012, data for supporting a marketplace (such as described in connection with other embodiments), and output data provided via output interfaces and ports 4010 from one or more data collection systems 102.
Methods and systems are disclosed herein for a self-organizing data marketplace for industrial IoT data, including where available data elements are organized in the marketplace for consumption by consumers based on training a self-organizing facility with a training set and feedback from measures of marketplace success. A marketplace may be set up initially to make available data collected from one or more industrial environments, such as presenting data by type, by source, by environment, by machine, by one or more patterns, or the like (such as in a menu or hierarchy). The marketplace may vary the data collected, the organization of the data, the presentation of the data (including pushing the data to external sites, providing links, configuring APIs by which the data may be accessed, and the like), the pricing of the data, or the like, such as under machine learning, which may vary different parameters of any of the foregoing. The machine learning facility may manage all of these parameters by self-organization, such as by varying parameters over time (including by varying elements of the data types presented), the data sourced used to obtain each type of data, the data structures presented (such as byte-like structures, fused or multiplexed structures (such as representing multiple sensor types), and statistical structures (such as representing various mathematical products of sensor information), among others), the pricing for the data, where the data is presented, how the data is presented (such as by APIs, by links, by push messaging, and the like), how the data is stored, how the data is obtained, and the like. As parameters are varied, feedback may be obtained as to measures of success, such as number of views, yield (e.g., price paid) per access, total yield, per unit profit, aggregate profit, and many others, and the self-organizing machine learning facility may promote configurations that improve measures of success and demote configurations that do not, so that, over time, the marketplace is progressively configured to present favorable combinations of data types (e.g., those that provide robust prediction of anticipated states of particular industrial environments of a given type), from favorable sources (e.g., those that are reliable, accurate and low priced), with effective pricing (e.g., pricing that tends to provide high aggregate profit from the marketplace). The marketplace may include spiders, web crawlers, and the like to seek input data sources, such as finding data pools, connected IoT devices, and the like that publish potentially relevant data. These may be trained by human users and improved by machine learning in a manner similar to that described elsewhere in this disclosure.
In embodiments, a platform is provided having a self-organizing data marketplace for industrial IoT data. Referring to
In embodiments, a cognitive data packaging system 4012 of the marketplace 4102 may use machine-based intelligence to package data, such as by automatically configuring packages of data in batches, streams, pools, or the like. In embodiments, packaging may be according to one or more rules, models, or parameters, such as by packaging or aggregating data that is likely to supplement or complement an existing model. For example, operating data from a group of similar machines (such as one or more industrial machines noted throughout this disclosure) may be aggregated together, such as based on metadata indicating the type of data or by recognizing features or characteristics in the data stream that indicate the nature of the data. In embodiments, packaging may occur using machine learning and cognitive capabilities, such as by learning what combinations, permutations, mixes, layers, and the like of input sources 116, sensors, information from data pools 4120 and information from data collection systems 102 are likely to satisfy user requirements or result in measures of success. Learning may be based on learning feedback 4012, such as learning based on measures determined in an analytic system 4018, such as system performance measures, data collection measures, analytic measures, and the like. In embodiments, success measures may be correlated to marketplace success measures, such as viewing of packages, engagement with packages, purchase or licensing of packages, payments made for packages, and the like. Such measures may be calculated in an analytic system 4018, including associating particular feedback measures with search terms and other inputs, so that the cognitive packaging system 4110 can find and configure packages that are designed to provide increased value to consumers and increased returns for data suppliers. In embodiments, the cognitive data packaging system 4110 can automatically vary packaging, such as using different combinations, permutations, mixes, and the like, and varying weights applied to given input sources, sensors, data pools and the like, using learning feedback 4012 to promote favorable packages and de-emphasize less favorable packages. This may occur using genetic programming and similar techniques that compare outcomes for different packages. Feedback may include state information from the state system 4020 (such as about various operating states, and the like), as well as about marketplace conditions and states, such as pricing and availability information for other data sources. Thus, an adaptive cognitive data packaging system 4110 is provided that automatically adapts to conditions to provide favorable packages of data for the marketplace 4102.
In embodiments, a cognitive data pricing system 4112 may be provided to set pricing for data packages. In embodiments, the data pricing system 4112 may use a set of rules, models, or the like, such as setting pricing based on supply conditions, demand conditions, pricing of various available sources, and the like. For example, pricing for a package may be configured to be set based on the sum of the prices of constituent elements (such as input sources, sensor data, or the like), or to be set based on a rule-based discount to the sum of prices for constituent elements, or the like. Rules and conditional logic may be applied, such as rules that factor in cost factors (such as bandwidth and network usage, peak demand factors, scarcity factors, and the like), rules that factor in utilization parameters (such as the purpose, domain, user, role, duration, or the like for a package) and many others. In embodiments, the cognitive data pricing system 4112 may include fully cognitive, intelligent features, such as using genetic programming including automatically varying pricing and tracking feedback on outcomes. Outcomes on which tracking feedback may be based include various financial yield metrics, utilization metrics and the like that may be provided by calculating metrics in an analytic system 4018 on data from the data transaction system 4114.
Methods and systems are disclosed herein for self-organizing data pools which may include self-organization of data pools based on utilization and/or yield metrics, including utilization and/or yield metrics that are tracked for a plurality of data pools. The data pools may initially comprise unstructured or loosely structured pools of data that contain data from industrial environments, such as sensor data from or about industrial machines or components. For example, a data pool might take streams of data from various machines or components in an environment, such as turbines, compressors, batteries, reactors, engines, motors, vehicles, pumps, rotors, axles, bearings, valves, and many others, with the data streams containing analog and/or digital sensor data (of a wide range of types), data published about operating conditions, diagnostic and fault data, identifying data for machines or components, asset tracking data, and many other types of data. Each stream may have an identifier in the pool, such as indicating its source, and optionally its type. The data pool may be accessed by external systems, such as through one or more interfaces or APIs (e.g., RESTful APIs), or by data integration elements (such as gateways, brokers, bridges, connectors, or the like), and the data pool may use similar capabilities to get access to available data streams. A data pool may be managed by a self-organizing machine learning facility, which may configure the data pool, such as by managing what sources are used for the pool, managing what streams are available, and managing APIs or other connections into and out of the data pool. The self-organization may take feedback such as based on measures of success that may include measures of utilization and yield. The measures of utilization and yield that may include may account for the cost of acquiring and/or storing data, as well as the benefits of the pool, measured either by profit or by other measures that may include user indications of usefulness, and the like. For example, a self-organizing data pool might recognize that chemical and radiation data for an energy production environment are regularly accessed and extracted, while vibration and temperature data have not been used, in which case the data pool might automatically reorganize, such as by ceasing storage of vibration and/or temperature data, or by obtaining better sources of such data. This automated reorganization can also apply to data structures, such as promoting different data types, different data sources, different data structures, and the like, through progressive iteration and feedback.
In embodiments, a platform is provided having self-organization of data pools based on utilization and/or yield metrics. In embodiments, the data pools 4020 may be self-organizing data pools 4020, such as being organized by cognitive capabilities as described throughout this disclosure. The data pools 4020 may self-organize in response to learning feedback 4012, such as based on feedback of measures and results, including calculated in an analytic system 4018. Organization may include determining what data or packages of data to store in a pool (such as representing particular combinations, permutations, aggregations, and the like), the structure of such data (such as in flat, hierarchical, linked, or other structures), the duration of storage, the nature of storage media (such as hard disks, flash memory, SSDs, network-based storage, or the like), the arrangement of storage bits, and other parameters. The content and nature of storage may be varied, such that a data pool 4020 may learn and adapt, such as based on states of the host system 112, one or more data collection systems 102, storage environment parameters (such as capacity, cost, and performance factors), data collection environment parameters, marketplace parameters, and many others. In embodiments, pools 4020 may learn and adapt, such as by variation of the above and other parameters in response to yield metrics (such as return on investment, optimization of power utilization, optimization of revenue, and the like).
Methods and systems are disclosed herein for training AI models based on industry-specific feedback, including training an AI model based on industry-specific feedback that reflects a measure of utilization, yield, or impact, and where the AI model operates on sensor data from an industrial environment. As noted above, these models may include operating models for industrial environments, machines, workflows, models for anticipating states, models for predicting fault and optimizing maintenance, models for self-organizing storage (on devices, in data pools and/or in the cloud), models for optimizing data transport (such as for optimizing network coding, network-condition-sensitive routing, and the like), models for optimizing data marketplaces, and many others.
In embodiments, a platform is provided having training AI models based on industry-specific feedback. In embodiments, the various embodiments of cognitive systems disclosed herein may take inputs and feedback from industry-specific and domain-specific sources 116 (such as relating to optimization of specific machines, devices, components, processes, and the like). Thus, learning and adaptation of storage organization, network usage, combination of sensor and input data, data pooling, data packaging, data pricing, and other features (such as for a marketplace 4102 or for other purposes of the host processing system 112) may be configured by learning on the domain-specific feedback measures of a given environment or application, such as an application involving IoT devices (such as an industrial environment). This may include optimization of efficiency (such as in electrical, electromechanical, magnetic, physical, thermodynamic, chemical and other processes and systems), optimization of outputs (such as for production of energy, materials, products, services and other outputs), prediction, avoidance and mitigation of faults (such as in the aforementioned systems and processes), optimization of performance measures (such as returns on investment, yields, profits, margins, revenues and the like), reduction of costs (including labor costs, bandwidth costs, data costs, material input costs, licensing costs, and many others), optimization of benefits (such as relating to safety, satisfaction, health), optimization of work flows (such as optimizing time and resource allocation to processes), and others.
Methods and systems are disclosed herein for a self-organized swarm of industrial data collectors, including a self-organizing swarm of industrial data collectors that organize among themselves to optimize data collection based on the capabilities and conditions of the members of the swarm. Each member of the swarm may be configured with intelligence, and the ability to coordinate with other members. For example, a member of the swarm may track information about what data other members are handling, so that data collection activities, data storage, data processing, and data publishing can be allocated intelligently across the swarm, taking into account conditions of the environment, capabilities of the members of the swarm, operating parameters, rules (such as from a rules engine that governs the operation of the swarm), and current conditions of the members. For example, among four collectors, one that has relatively low current power levels (such as a low battery), might be temporarily allocated the role of publishing data, because it may receive a dose of power from a reader or interrogation device (such as an RFID reader) when it needs to publish the data. A second collector with good power levels and robust processing capability might be assigned more complex functions, such as processing data, fusing data, organizing the rest of the swarm (including self-organization under machine learning, such that the swarm is optimized over time, including by adjusting operating parameters, rules, and the like based on feedback), and the like. A third collector in the swarm with robust storage capabilities might be assigned the task of collecting and storing a category of data, such as vibration sensor data, that consumes considerable bandwidth. A fourth collector in the swarm, such as one with lower storage capabilities, might be assigned the role of collecting data that can usually be discarded, such as data on current diagnostic conditions, where only data on faults needs to be maintained and passed along. Members of a swarm may connect by peer-to-peer relationships by using a member as a “master” or “hub,” or by having them connect in a series or ring, where each member passes along data (including commands) to the next, and is aware of the nature of the capabilities and commands that are suitable for the preceding and/or next member. The swarm may be used for allocation of storage across it (such as using memory of each memory as an aggregate data store. In these examples, the aggregate data store may support a distributed ledger, which may store transaction data, such as for transactions involving data collected by the swarm, transactions occurring in the industrial environment, or the like. In embodiments, the transaction data may also include data used to manage the swarm, the environment, or a machine or components thereof. The swarm may self-organize, either by machine learning capability disposed on one or more members of the swarm, or based on instructions from an external machine learning facility, which may optimize storage, data collection, data processing, data presentation, data transport, and other functions based on managing parameters that are relevant to each. The machine learning facility may start with an initial configuration and vary parameters of the swarm relevant to any of the foregoing (also including varying the membership of the swarm), such as iterating based on feedback to the machine learning facility regarding measures of success (such as utilization measures, efficiency measures, measures of success in prediction or anticipation of states, productivity measures, yield measures, profit measures, and others). Over time, the swarm may be optimized to a favorable configuration to achieve the desired measure of success for an owner, operator, or host of an industrial environment or a machine, component, or process thereof.

Methods and systems are disclosed herein for an industrial IoT distributed ledger, including a distributed ledger supporting the tracking of transactions executed in an automated data marketplace for industrial IoT data. A distributed ledger may distribute storage across devices, using a secure protocol, such as those used for cryptocurrencies (such as the Blockchain™ protocol used to support the Bitcoin™ currency). A ledger or similar transaction record, which may comprise a structure where each successive member of a chain stores data for previous transactions, and a competition can be established to determine which of alternative data stored data structures is “best” (such as being most complete), can be stored across data collectors, industrial machines or components, data pools, data marketplaces, cloud computing elements, servers, and/or on the IT infrastructure of an enterprise (such as an owner, operator or host of an industrial environment or of the systems disclosed herein). The ledger or transaction may be optimized by machine learning, such as to provide storage efficiency, security, redundancy, or the like.
In embodiments, the cognitive data marketplace 4102 may use a secure architecture for tracking and resolving transactions, such as a distributed ledger 4004, wherein transactions in data packages are tracked in a chained, distributed data structure, such as a Blockchain™, allowing forensic analysis and validation where individual devices store a portion of the ledger representing transactions in data packages. The distributed ledger 4004 may be distributed to IoT devices, to data pools 4020, to data collection systems 102, and the like, so that transaction information can be verified without reliance on a single, central repository of information. The transaction system 4114 may be configured to store data in the distributed ledger 4004 and to retrieve data from it (and from constituent devices) in order to resolve transactions. Thus, a distributed ledger 4004 for handling transactions in data, such as for packages of IoT data, is provided. In embodiments, the self-organizing storage system 4028 may be used for optimizing storage of distributed ledger data, as well as for organizing storage of packages of data, such as IoT data, that can be presented in the marketplace 4102.
Methods and systems are disclosed herein for a network-sensitive collector, including a network condition-sensitive, self-organizing, multi-sensor data collector that can optimize based on bandwidth, quality of service, pricing and/or other network conditions. Network sensitivity can include awareness of the price of data transport (such as allowing the system to pull or push data during off-peak periods or within the available parameters of paid data plans), the quality of the network (such as to avoid periods where errors are likely), the quality of environmental conditions (such as delaying transmission until signal quality is good, such as when a collector emerges from a shielded environment, avoiding wasting use of power when seeking a signal when shielded, such as by large metal structures typically of industrial environments), and the like.
Methods and systems are disclosed herein for a remotely organized universal data collector that can power up and down sensor interfaces based on need and/or conditions identified in an industrial data collection environment. For example, interfaces can recognize what sensors are available and interfaces and/or processors can be turned on to take input from such sensors, including hardware interfaces that allow the sensors to plug in to the data collector, wireless data interfaces (such as where the collector can ping the sensor, optionally providing some power via an interrogation signal), and software interfaces (such as for handling particular types of data). Thus, a collector that is capable of handling various kinds of data can be configured to adapt to the particular use in a given environment. In embodiments, configuration may be automatic or under machine learning, which may improve configuration by optimizing parameters based on feedback measures over time.
Methods and systems are disclosed herein for self-organizing storage for a multi-sensor data collector, including self-organizing storage for a multi-sensor data collector for industrial sensor data. Self-organizing storage may allocate storage based on application of machine learning, which may improve storage configuration based on feedback measure over time. Storage may be optimized by configuring what data types are used (e.g., byte-like structures, structures representing fused data from multiple sensors, structures representing statistics or measures calculated by applying mathematical functions on data, and the like), by configuring compression, by configuring data storage duration, by configuring write strategies (such as by striping data across multiple storage devices, using protocols where one device stores instructions for other devices in a chain, and the like), and by configuring storage hierarchies, such as by providing pre-calculated intermediate statistics to facilitate more rapid access to frequently accessed data items. Thus, highly intelligent storage systems may be configured and optimized, based on feedback, over time.
Methods and systems are disclosed herein for self-organizing network coding for a multi-sensor data network, including self-organizing network coding for a data network that transports data from multiple sensors in an industrial data collection environment. Network coding, including random linear network coding, can enable highly efficient and reliable transport of large amounts of data over various kinds of networks. Different network coding configurations can be selected, based on machine learning, to optimize network coding and other network transport characteristics based on network conditions, environmental conditions, and other factors, such as the nature of the data being transported, environmental conditions, operating conditions, and the like (including by training a network coding selection model over time based on feedback of measures of success, such as any of the measures described herein).
In embodiments, a platform is provided having a self-organizing network coding for multi-sensor data network. A cognitive system may vary one or more parameters for networking, such as network type selection (e.g., selecting among available local, cellular, satellite, Wi-Fi, Bluetooth™, NFC, Zigbee® and other networks), network selection (such as selecting a specific network, such as one that is known to have desired security features), network coding selection (such as selecting a type of network coding for efficient transport[such as random linear network coding, fixed coding, and others]), network timing selection (such as configuring delivery based on network pricing conditions, traffic and the like), network feature selection (such as selecting cognitive features, security features, and the like), network conditions (such as network quality based on current environmental or operation conditions), network feature selection (such as enabling available authentication, permission and similar systems), network protocol selection (such as among HTTP, IP, TCP/IP, cellular, satellite, serial, packet, streaming, and many other protocols), and others. Given bandwidth constraints, price variations, sensitivity to environmental factors, security concerns, and the like, selecting the optimal network configuration can be highly complex and situation dependent. The self-organizing networking system 4030 may vary combinations and permutations of these parameters while taking input from a learning feedback system 4012 such as using information from the analytic system 4018 about various measures of outcomes. In the many examples, outcomes may include overall system measures, analytic success measures, and local performance indicators. In embodiments, input from a learning feedback system 4012 may include information from various sensors and input sources 116, information from the state system 4020 about states (such as events, environmental conditions, operating conditions, and many others, or other information) or taking other inputs. By variation and selection of alternative configurations of networking parameters in different states, the self-organizing networking system may find configurations that are well-adapted to the environment that is being monitored or controlled by the host system 112, such as the instance where one or more data collection systems 102 are located and that are well-adapted to emerging network conditions. Thus, a self-organizing, network-condition-adaptive data collection system is provided.

Methods and systems are disclosed herein for a presentation layer for AR/VR industrial glasses, where heat map elements are presented based on patterns and/or parameters in collected data. Methods and systems are disclosed herein for condition-sensitive, self-organized tuning of AR/VR interfaces based on feedback metrics and/or training in industrial environments. In embodiments, any of the data, measures, and the like described throughout this disclosure can be presented by visual elements, overlays, and the like for presentation in the AR/VR interfaces, such as in industrial glasses, on AR/VR interfaces on smart phones or tablets, on AR/VR interfaces on data collectors (which may be embodied in smart phones or tablets), on displays located on machines or components, and/or on displays located in industrial environments.
In embodiments, a platform is provided having heat maps displaying collected data for AR/VR. In embodiments, a platform is provided having heat maps 4204 displaying collected data from a data collection system 102 for providing input to an AR/VR interface 4208. In embodiments, the heat map interface 4304 is provided as an output for a data collection system 102, such as for handling and providing information for visualization of various sensor data and other data (such as map data, analog sensor data, and other data), such as to one or more components of the data collection system 102 or to another system, such as a mobile device, tablet, dashboard, computer, AR/VR device, or the like. A data collection system 102 may be provided in a form factor suitable for delivering visual input to a user, such as the presentation of a map that includes indicators of levels of analog and digital sensor data (such as data indicating levels of rotation, vibration, heating or cooling, pressure, and many other conditions). In such cases, data collection systems 102 may be integrated with equipment, or the like that are used by individuals responsible for operating or monitoring an industrial environment. In embodiments, signals from various sensors or input sources (or selective combinations, permutations, mixes, and the like, as managed by one or more of the cognitive input selection systems 4004, 4014) may provide input data to a heat map. Coordinates may include real world location coordinates (such as geo-location or location on a map of an environment), as well as other coordinates, such as time-based coordinates, frequency-based coordinates, or other coordinates that allow for representation of analog sensor signals, digital signals, input source information, and various combinations, in a map-based visualization, such that colors may represent varying levels of input along the relevant dimensions. For example, if a nearby industrial machine is overheating, the heat map interface may alert a user by showing a machine in bright red. If a system is experiencing unusual vibrations, the heat map interface may show a different color for a visual element for the machine, or it may cause an icon or display element representing the machine to vibrate in the interface, calling attention to the element. Clicking, touching, or otherwise interacting with the map can allow a user to drill down and see underlying sensor or input data that is used as an input to the heat map display. Thus, through various forms of display, a data collection system 102 may inform users of the need to attend to one or more devices, machines, or other factors, such as those in an industrial environment, without requiring them to read text-based messages or input. The heat map interface, and selection of what outputs should be provided, may be considered in the cognitive input selection systems 4004, 4014. For example, user behavior (such as responses to inputs or displays) may be monitored and analyzed in an analytic system 4018, and feedback may be provided through the learning feedback system 4012, so that signals may be provided based on the right collection or package of sensors and inputs, at the right time and in the right manner, to optimize the effectiveness of the heat map UI 4304. This may include rule-based or model-based feedback (such as feedback providing outputs that correspond in some logical fashion to the source data that is being conveyed). In embodiments, a cognitive heat map system may be provided, where selection of inputs or triggers for heat map displays, selection of outputs, colors, visual representation elements, timing, intensity levels, durations and other parameters (or weights applied to them) may be varied in a process of variation, promotion and selection (such as selection using genetic programming) with feedback based on real world responses to feedback in actual situations or based on results of simulation and testing of user behavior. Thus, an adaptive heat map interface for a data collection system 102, or data collected thereby 102, or data handled by a host processing system 112, is provided, which may learn and adapt feedback to satisfy requirements and to optimize the impact on user behavior and reaction, such as for overall system outcomes, data collection outcomes, analytic outcomes, and the like.
In embodiments, a platform is provided having automatically tuned AR/VR visualization of data collected by a data collector. In embodiments, a platform is provided having an automatically tuned AR/VR visualization system 4308 for visualization of data collected by a data collection system 102, such as the case where the data collection system 102 has an AR/VR interface 4208 or provides input to an AR/VR interface 4308 (such as a mobile phone positioned in a virtual reality or AR headset, a set of AR glasses, or the like). In embodiments, the AR/VR system 4308 is provided as an output interface of a data collection system 102, such as a system for handling and providing information for visualization of various sensor data and other data (such as map data, analog sensor data, and other data), such as to one or more components of the data collection system 102 or to another system, such as a mobile device, tablet, dashboard, computer, AR/VR device, or the like. A data collection system 102 may be provided in a form factor suitable for delivering AR or VR visual, auditory, or other sensory input to a user, such as by presenting one or more displays such as 3D-realistic visualizations, objects, maps, camera overlays, or other overlay elements, maps and the like that include or correspond to indicators of levels of analog and digital sensor data (such as data indicating levels of rotation, vibration, heating or cooling, pressure and many other conditions, to input sources 116, or the like). In such cases, data collection systems 102 may be integrated with equipment, or the like that are used by individuals responsible for operating or monitoring an industrial environment.
In embodiments, signals from various sensors or input sources (or selective combinations, permutations, mixes, and the like as managed by one or more of the cognitive input selection systems 4004, 4014) may provide input data to populate, configure, modify, or otherwise determine the AR/VR element. Visual elements may include a wide range of icons, map elements, menu elements, sliders, toggles, colors, shapes, sizes, and the like, for representation of analog sensor signals, digital signals, input source information, and various combinations. In many examples, colors, shapes, and sizes of visual overlay elements may represent varying levels of input along the relevant dimensions for a sensor or combination of sensors. In further examples, if a nearby industrial machine is overheating, an AR element may alert a user by showing an icon representing that type of machine in flashing red color in a portion of the display of a pair of AR glasses. If a system is experiencing unusual vibrations, a virtual reality interface showing visualization of the components of the machine (such as an overlay of a camera view of the machine with 3D visualization elements) may show a vibrating component in a highlighted color, with motion, or the like, to ensure the component stands out in a virtual reality environment being used to help a user monitor or service the machine. Clicking, touching, moving eyes toward, or otherwise interacting with a visual element in an AR/VR interface may allow a user to drilldown and see underlying sensor or input data that is used as an input to the display. Thus, through various forms of display, a data collection system 102 may inform users of the need to attend to one or more devices, machines, or other factors (such as in an industrial environment), without requiring them to read text-based messages or input or divert attention from the applicable environment (whether it is a real environment with AR features or a virtual environment, such as for simulation, training, or the like).
The AR/VR output interface 4208, and selection and configuration of what outputs or displays should be provided, may be handled in the cognitive input selection systems 4004, 4014. For example, user behavior (such as responses to inputs or displays) may be monitored and analyzed in an analytic system 4018, and feedback may be provided through the learning feedback system 4012, so that AR/VR display signals may be provided based on the right collection or package of sensors and inputs, at the right time and in the right manner, to optimize the effectiveness of the AR/VR UI 4308. This may include rule-based or model-based feedback (such as providing outputs that correspond in some logical fashion to the source data that is being conveyed). In embodiments, a cognitively tuned AR/VR interface control system 4308 may be provided, where selection of inputs or triggers for AR/VR display elements, selection of outputs (such as colors, visual representation elements, timing, intensity levels, durations and other parameters [or weights applied to them]) and other parameters of a VR/AR environment may be varied in a process of variation, promotion and selection (such as the use of genetic programming) with feedback based on real world responses in actual situations or based on results of simulation and testing of user behavior. Thus, an adaptive, tuned AR/VR interface for a data collection system 102, or data collected thereby 102, or data handled by a host processing system 112, is provided, which may learn and adapt feedback to satisfy requirements and to optimize the impact on user behavior and reaction, such as for overall system outcomes, data collection outcomes, analytic outcomes, and the like.

The response circuit 8110 may acquire data from a plurality of sensors of different ranges. The response circuit 8110 may recommend an alternate sensor. The response circuit 8110 may issue an alarm or an alert.
In embodiments, the response circuit 8110 may cause the data acquisition circuit 8104 to enable or disable the processing of detection values corresponding to certain sensors based on the component status. This may include switching to sensors having different response rates, sensitivity, ranges, and the like; accessing new sensors or types of sensors, accessing data from multiple sensors, and the like.

An embodiment of a data monitoring device 8500 is shown in
The selection of the plurality of sensors 8506 for a data monitoring device 8500 designed for a specific component or piece of equipment may depend on a variety of considerations such as accessibility for installing new sensors, incorporation of sensors in the initial design, anticipated operational and failure conditions, reliability of the sensors, and the like. The impact of failure may drive the extent to which a component or piece of equipment is monitored with more sensors and/or higher capability sensors being dedicated to systems where unexpected or undetected failure would be costly or have severe consequences.

In embodiments, as illustrated in
In an embodiment, as illustrated in
The signal evaluation circuit 8508 may include one or more components such as a phase detection circuit 8528 to determine a phase difference between two time-based signals, a phase lock loop circuit 8530 to adjust the relative phase of a signal such that it is aligned with a second signal, timer or reference signal, and/or a band pass filter circuit 8532 which may be used to separate out signals occurring at different frequencies. An example band pass filter circuit 8532 includes any filtering operations understood in the art, including at least a low-pass filter, a high-pass filter, and/or a band pass filter—for example to exclude or reduce frequencies that are not of interest for a particular determination, and/or to enhance the signal for frequencies of interest. Additionally, or alternatively, a band pass filter circuit 8532 includes one or more notch filters or other filtering mechanism to narrow ranges of frequencies (e.g., frequencies from a known source of noise). This may be used to filter out dominant frequency signals such as the overall rotation, and may help enable the evaluation of low amplitude signals at frequencies associated with torsion, bearing failure and the like.
In embodiments, understanding the relative differences may be enabled by a phase detection circuit 8528 to determine a phase difference between two signals. It may be of value to understand a relative phase offset, if any, between signals such as when a periodic vibration occurs relative to a relative rotation of a piece of equipment. In embodiments, there may be value in understanding where in a cycle shaft vibrations occur relative to a motor control input to better balance the control of the motor. This may be particularly true for systems and components that are operating at relative slow RPMs. Understanding of the phase difference between two signals or between those signals and a timer may enable establishing a relationship between a signal value and where it occurs in a process or rotation. Understanding relative phase differences may help in evaluating the relationship between different components of a system such as in the creation of a vibrational model for an Operational Deflection Shape (ODS).
The signal evaluation circuit 8544 may perform frequency analysis using techniques such as a digital Fast Fourier transform (FFT), Laplace transform, Z-transform, wavelet transform, other frequency domain transform, or other digital or analog signal analysis techniques, including, without limitation, complex analysis, including complex phase evolution analysis. An overall rotational speed or tachometer may be derived from data from sensors such as rotational velocity meters, accelerometers, displacement meters and the like. Additional frequencies of interest may also be identified. These may include frequencies near the overall rotational speed as well as frequencies higher than that of the rotational speed. These may include frequencies that are nonsynchronous with an overall rotational speed. Signals observed at frequencies that are multiples of the rotational speed may be due to bearing induced vibrations or other behaviors or situations involving bearings. In some instances, these frequencies may be in the range of one times the rotational speed, two times the rotational speed, three times the rotational speed, and the like, up to 3.15 to 15 times the rotational speed, or higher. In some embodiments, the signal evaluation circuit 8544 may select RC components for a band pass filter circuit 8532 based on overall rotational speed to create a band pass filter circuit 8532 to remove signals at expected frequencies such as the overall rotational speed, to facilitate identification of small amplitude signals at other frequencies. In embodiments, variable components may be selected, such that adjustments may be made in keeping with changes in the rotational speed, so that the band pass filter may be a variable band pass filter. This may occur under control of automatically self-adjusting circuit elements, or under control of a processor, including automated control based on a model of the circuit behavior, where a rotational speed indicator or other data is provided as a basis for control.
In embodiments, rather than performing frequency analysis, the signal evaluation circuit 8544 may utilize the time-based detection values to perform transitory signal analysis. These may include identifying abrupt changes in signal amplitude including changes where the change in amplitude exceeds a predetermined value or exists for a certain duration. In embodiments, the time-based sensor data may be aligned with a timer or reference signal allowing the time-based sensor data to be aligned with, for example, a time or location in a cycle. Additional processing to look at frequency changes over time may include the use of Short-Time Fourier Transforms (STFT) or a wavelet transform.
In embodiments, frequency-based techniques and time-based techniques may be combined, such as using time-based techniques to determine discrete time periods during which given operational modes or states are occurring and using frequency-based techniques to determine behavior within one or more of the discrete time periods.
In embodiments, the signal evaluation circuit may utilize demodulation techniques for signals obtained from equipment running at slow speeds such as paper and pulp machines, mining equipment, and the like. A signal evaluation circuit employing a demodulation technique may comprise a band-pass filter circuit, a rectifier circuit, and/or a low pass circuit prior to transforming the data to the frequency domain
The response circuit 85108710 may further comprise evaluating the results of the signal evaluation circuit 85088544 and, based on certain criteria, initiating an action. Criteria may include a predetermined maximum or minimum value for a detection value from a specific sensor, a value of a sensor's corresponding detection value over time, a change in value, a rate of change in value, and/or an accumulated value (e.g., a time spent above/below a threshold value, a weighted time spent above/below one or more threshold values, and/or an area of the detected value above/below one or more threshold values). The criteria may include a sensor's detection values at certain frequencies or phases where the frequencies or phases may be based on the equipment geometry, equipment control schemes, system input, historical data, current operating conditions, and/or an anticipated response. The criteria may comprise combinations of data from different sensors such as relative values, relative changes in value, relative rates of change in value, relative values over time, and the like. The relative criteria may change with other data or information such as process stage, type of product being processed, type of equipment, ambient temperature and humidity, external vibrations from other equipment, and the like. The relative criteria may include level of synchronicity with an overall rotational speed, such as to differentiate between vibration induced by bearings and vibrations resulting from the equipment design. In embodiments, the criteria may be reflected in one or more calculated statistics or metrics (including ones generated by further calculations on multiple criteria or statistics), which in turn may be used for processing (such as on board a data collector or by an external system), such as to be provided as an input to one or more of the machine learning capabilities described in this disclosure, to a control system (which may be an on-board data collector or remote, such as to control selection of data inputs, multiplexing of sensor data, storage, or the like), or as a data element that is an input to another system, such as a data stream or data package that may be available to a data marketplace, a SCADA system, a remote control system, a maintenance system, an analytic system, or other system.
In an illustrative and non-limiting example, an alert may be issued if the vibrational amplitude and/or frequency exceeds a predetermined maximum value, if there is a change or rate of change that exceeds a predetermined acceptable range, and/or if an accumulated value based on vibrational amplitude and/or frequency exceeds a threshold. Certain embodiments are described herein as detected values exceeding thresholds or predetermined values, but detected values may also fall below thresholds or predetermined values—for example where an amount of change in the detected value is expected to occur, but detected values indicate that the change may not have occurred. For example, and without limitation, vibrational data may indicate system agitation levels, properly operating equipment, or the like, and vibrational data below amplitude and/or frequency thresholds may be an indication of a process that is not operating according to expectations. Except where the context clearly indicates otherwise, any description herein describing a determination of a value above a threshold and/or exceeding a predetermined or expected value is understood to include determination of a value below a threshold and/or falling below a predetermined or expected value.
The predetermined acceptable range may be based on anticipated system response or vibration based on the equipment geometry and control scheme such as number of bearings, relative rotational speed, influx of power to the system at a certain frequency, and the like. The predetermined acceptable range may also be based on long term analysis of detection values across a plurality of similar equipment and components and correlation of data with equipment failure. Based on vibration phase information, a physical location of a problem may be identified. Based on the vibration phase information system design flaws, off-nominal operation, and/or component or process failures may be identified. In some embodiments, an alert may be issued based on changes or rates of change in the data over time such as increasing amplitude or shifts in the frequencies or phases at which a vibration occurs. In some embodiments, an alert may be issued based on accumulated values such as time spent over a threshold, weighted time spent over one or more thresholds, and/or an area of a curve of the detected value over one or more thresholds. In embodiments, an alert may be issued based on a combination of data from different sensors such as relative changes in value, or relative rates of change in amplitude, frequency of phase in addition to values of non-phase sensors such as temperature, humidity and the like. For example, an increase in temperature and energy at certain frequencies may indicate a hot bearing that is starting to fail. In embodiments, the relative criteria for an alarm may change with other data or information such as process stage, type of product being processed on equipment, ambient temperature and humidity, external vibrations from other equipment and the like.
In embodiments, response circuit 8510 may cause the data acquisition circuit 8504 to enable or disable the processing of detection values corresponding to certain sensors based on the some of the criteria discussed above. This may include switching to sensors having different response rates, sensitivity, ranges, and the like; accessing new sensors or types of sensors, and the like. Switching may be undertaken based on a model, a set of rules, or the like. In embodiments, switching may be under control of a machine learning system, such that switching is controlled based on one or more metrics of success, combined with input data, over a set of trials, which may occur under supervision of a human supervisor or under control of an automated system. Switching may involve switching from one input port to another (such as to switch from one sensor to another). Switching may involve altering the multiplexing of data, such as combining different streams under different circumstances. Switching may involve activating a system to obtain additional data, such as moving a mobile system (such as a robotic or drone system), to a location where different or additional data is available (such as positioning an image sensor for a different view or positioning a sonar sensor for a different direction of collection) or to a location where different sensors can be accessed (such as moving a collector to connect up to a sensor that is disposed at a location in an environment by a wired or wireless connection). The response circuit 8510 may make recommendations for the replacement of certain sensors in the future with sensors having different response rates, sensitivity, ranges, and the like. The response circuit 8510 may recommend design alterations for future embodiments of the component, the piece of equipment, the operating conditions, the process, and the like.
In embodiments, the response circuit 8510 may recommend maintenance at an upcoming process stop or initiate a maintenance call. The response circuit 8510 may recommend changes in process or operating parameters to remotely balance the piece of equipment. In embodiments, the response circuit 8510 may implement or recommend process changes—for example to lower the utilization of a component that is near a maintenance interval, operating off-nominally, or failed for purpose but still at least partially operational, to change the operating speed of a component (such as to put it in a lower-demand mode), to initiate amelioration of an issue (such as to signal for additional lubrication of a roller bearing set, or to signal for an alignment process for a system that is out of balance), and the like.
In embodiments, as shown in
In embodiments, based on relevant operating conditions and/or failure modes which may occur in as sensor values approach one or more criteria, the signal evaluation circuit 8544 may store data in the data storage circuit 8542 based on the fit of data relative to one or more criteria, such as those described throughout this disclosure. Based on one sensor input meeting or approaching specified criteria or range, the signal evaluation circuit 8544 may store additional data such as RPMs, component loads, temperatures, pressures, vibrations or other sensor data of the types described throughout this disclosure. The signal evaluation circuit 8544 may store data at a higher data rate for greater granularity in future processing, the ability to reprocess at different sampling rates, and/or to enable diagnosing or post-processing of system information where operational data of interest is flagged, and the like.
In embodiments, as shown in
In embodiments, as illustrated in
The monitoring application may then analyze the selected data set. For example, data from a single component may be analyzed over different time periods such as one operating cycle, several operating cycles, a month, a year, or the like. Data from multiple components of the same type may also be analyzed over different time periods. Trends in the data such as changes in frequency or amplitude may be correlated with failure and maintenance records associated with the same component or piece of equipment. Trends in the data such as changing rates of change associated with start-up or different points in the process may be identified. Additional data may be introduced into the analysis such as output product quality, output quantity (such as per unit of time), indicated success or failure of a process, and the like. Correlation of trends and values for different types of data may be analyzed to identify those parameters whose short-term analysis might provide the best prediction regarding expected performance. This information may be transmitted back to the monitoring device to update types of data collected and analyzed locally or to influence the design of future monitoring devices.
In an illustrative and non-limiting example, the monitoring device may be used to collect and process sensor data to measure mechanical torque. The monitoring device may be in communication with or include a high resolution, high speed vibration sensor to collect data over an extended period of time, enough to measure multiple cycles of rotation. For gear driven equipment, the sampling resolution should be such that the number of samples taken per cycle is at least equal to the number of gear teeth driving the component. It will be understood that a lower sampling resolution may also be utilized, which may result in a lower confidence determination and/or taking data over a longer period of time to develop sufficient statistical confidence. This data may then be used in the generation of a phase reference (relative probe) or tachometer signal for a piece of equipment. This phase reference may be used to align phase data such as vibrational data or acceleration data from multiple sensors located at different positions on a component or on different components within a system. This information may facilitate the determination of torque for different components or the generation of an Operational Deflection Shape (ODS), indicating the extent of mechanical deflection of one or more components during an operational mode, which in turn may be used to measure mechanical torque in the component.
The higher resolution data stream may provide additional data for the detection of transitory signals in low speed operations. The identification of transitory signals may enable the identification of defects in a piece of equipment or component.
In an illustrative and non-limiting example, the monitoring device may be used to identify mechanical jitter for use in failure prediction models. The monitoring device may begin acquiring data when the piece of equipment starts up through ramping up to operating speed and then during operation. Once at operating speed, it is anticipated that the torsional jitter should be minimal and changes in torsion during this phase may be indicative of cracks, bearing faults and the like. Additionally, known torsions may be removed from the signal to facilitate in the identification of unanticipated torsions resulting from system design flaws or component wear. Having phase information associated with the data collected at operating speed may facilitate identification of a location of vibration and potential component wear. Relative phase information for a plurality of sensors located throughout a machine may facilitate the evaluation of torsion as it is propagated through a piece of equipment.

In embodiments, information about the health of a component or piece of industrial equipment may be obtained by comparing the values of multiple signals at the same point in a process. This may be accomplished by aligning a signal relative to other related data signals, timers, or reference signals. An embodiment of a data monitoring device 8700, 8718 is shown in
The data monitoring device may include a plurality of sensors 8706 communicatively coupled to a controller 8702. The plurality of sensors 8706 may be wired to ports on the data acquisition circuit 8704. The plurality of sensors 8706 may be wirelessly connected to the data acquisition circuit 8704 which may be able to access detection values corresponding to the output of at least one of the plurality of sensors 8706 where the sensors 8706 may be capturing data on different operational aspects of a piece of equipment or an operating component. In embodiments, as illustrated in
The selection of the plurality of sensors 87068724 for connection to a data monitoring device 87008718 designed for a specific component or piece of equipment may depend on a variety of considerations such as accessibility for installing new sensors, incorporation of sensors in the initial design, anticipated operational and failure conditions, resolution desired at various positions in a process or plant, reliability of the sensors, and the like. The impact of a failure, time response of a failure (e.g., warning time and/or off-nominal modes occurring before failure), likelihood of failure, and/or sensitivity required and/or difficulty to detect failed conditions may drive the extent to which a component or piece of equipment is monitored with more sensors and/or higher capability sensors being dedicated to systems where unexpected or undetected failure would be costly or have severe consequences.
The signal evaluation circuit 8708 may process the detection values to obtain information about a component or piece of equipment being monitored. Information extracted by the signal evaluation circuit 8708 may comprise information regarding what point or time in a process corresponds with a detection value where the point in time is based on a timing signal generated by the timer circuit 8714. The start of the timing signal may be generated by detecting an edge of a control signal such as a rising edge, falling edge or both where the control signal may be associated with the start of a process. The start of the timing signal may be triggered by an initial movement of a component or piece of equipment. The start of the timing signal may be triggered by an initial flow through a pipe or opening or by a flow achieving a predetermined rate. The start of the timing signal may be triggered by a state value indicating a process has commenced—for example the state of a switch, button, data value provided to indicate the process has commenced, or the like. Information extracted may comprise information regarding a difference in phase, determined by the phase detection circuit 8712, between a stream of detection value and the time signal generated by the timer circuit 8714. Information extracted may comprise information regarding a difference in phase between one stream of detection values and a second stream of detection values where the first stream of detection values is used as a basis or trigger for a timing signal generated by the timer circuit.
Depending on the type of equipment, the component being measured, the environment in which the equipment is operating and the like, sensors 87068724 may comprise one or more of, without limitation, a thermometer, a hygrometer, a voltage sensor, a current sensor, an accelerometer, a velocity detector, a light or electromagnetic sensor (e.g., determining temperature, composition and/or spectral analysis, and/or object position or movement), an image sensor, a displacement sensor, a turbidity meter, a viscosity meter, a load sensor, a tri-axial sensor, a tachometer, a fluid pressure meter, an air flow meter, a horsepower meter, a flow rate meter, a fluid particle detector, an acoustical sensor, a pH sensor, and the like.
The sensors 87068724 may provide a stream of data over time that has a phase component, such as acceleration or vibration, allowing for the evaluation of phase or frequency analysis of different operational aspects of a piece of equipment or an operating component. The sensors 87068724 may provide a stream of data that is not phase based such as temperature, humidity, load, and the like. The sensors 87068724 may provide a continuous or near continuous stream of data over time, periodic readings, event-driven readings, and/or readings according to a selected interval or schedule.
In embodiments, as illustrated in
The response circuit 8710 may further comprise evaluating the results of the signal evaluation circuit 8708 and, based on certain criteria, initiating an action. The criteria may include a sensor's detection values at certain frequencies or phases relative to the timer signal where the frequencies or phases of interest may be based on the equipment geometry, equipment control schemes, system input, historical data, current operating conditions, and/or an anticipated response. Criteria may include a predetermined maximum or minimum value for a detection value from a specific sensor, a cumulative value of a sensor's corresponding detection value over time, a change in value, a rate of change in value, and/or an accumulated value (e.g., a time spent above/below a threshold value, a weighted time spent above/below one or more threshold values, and/or an area of the detected value above/below one or more threshold values). The criteria may comprise combinations of data from different sensors such as relative values, relative changes in value, relative rates of change in value, relative values over time, and the like. The relative criteria may change with other data or information such as process stage, type of product being processed, type of equipment, ambient temperature and humidity, external vibrations from other equipment, and the like.
Certain embodiments are described herein as detected values exceeding thresholds or predetermined values, but detected values may also fall below thresholds or predetermined values—for example where an amount of change in the detected value is expected to occur, but detected values indicate that the change may not have occurred. For example, and without limitation, vibrational data may indicate system agitation levels, properly operating equipment, or the like, and vibrational data below amplitude and/or frequency thresholds may be an indication of a process that is not operating according to expectations. Except where the context clearly indicates otherwise, any description herein describing a determination of a value above a threshold and/or exceeding a predetermined or expected value is understood to include determination of a value below a threshold and/or falling below a predetermined or expected value.
The predetermined acceptable range may be based on anticipated system response or vibration based on the equipment geometry and control scheme such as number of bearings, relative rotational speed, influx of power to the system at a certain frequency, and the like. The predetermined acceptable range may also be based on long term analysis of detection values across a plurality of similar equipment and components and correlation of data with equipment failure.
In some embodiments, an alert may be issued based on the some of the criteria discussed above. In an illustrative example, an increase in temperature and energy at certain frequencies may indicate a hot bearing that is starting to fail. In embodiments, the relative criteria for an alarm may change with other data or information such as process stage, type of product being processed on equipment, ambient temperature and humidity, external vibrations from other equipment and the like. In an illustrative and non-limiting example, the response circuit 8710 may initiate an alert if a vibrational amplitude and/or frequency exceeds a predetermined maximum value, if there is a change or rate of change that exceeds a predetermined acceptable range, and/or if an accumulated value based on vibrational amplitude and/or frequency exceeds a threshold.
In embodiments, response circuit 8710 may cause the data acquisition circuit 8704 to enable or disable the processing of detection values corresponding to certain sensors based on the some of the criteria discussed above. This may include switching to sensors having different response rates, sensitivity, ranges, and the like; accessing new sensors or types of sensors, and the like. This switching may be implemented by changing the control signals for a multiplexer circuit 8736 and/or by turning on or off certain input sections of the multiplexer circuit 8736. The response circuit 8710 may make recommendations for the replacement of certain sensors in the future with sensors having different response rates, sensitivity, ranges, and the like. The response circuit 8710 may recommend design alterations for future embodiments of the component, the piece of equipment, the operating conditions, the process, and the like.
In embodiments, the response circuit 8710 may recommend maintenance at an upcoming process stop or initiate a maintenance call. The response circuit 8710 may recommend changes in process or operating parameters to remotely balance the piece of equipment. In embodiments, the response circuit 8710 may implement or recommend process changes—for example to lower the utilization of a component that is near a maintenance interval, operating off-nominally, or failed for purpose but still at least partially operational. In an illustrative example, vibration phase information, derived by the phase detection circuit 8712 relative to a timer signal from the timer circuit 8714, may be indicative of a physical location of a problem. Based on the vibration phase information, system design flaws, off-nominal operation, and/or component or process failures may be identified.
In embodiments, based on relevant operating conditions and/or failure modes which may occur in as sensor values approach one or more criteria, the signal evaluation circuit 8708 may store data in the data storage circuit 8716 based on the fit of data relative to one or more criteria. Based on one sensor input meeting or approaching specified criteria or range, the signal evaluation circuit 8708 may store additional data such as RPMs, component loads, temperatures, pressures, vibrations in the data storage circuit 8716. The signal evaluation circuit 8708 may store data at a higher data rate for greater granularity in future processing, the ability to reprocess at different sampling rates, and/or to enable diagnosing or post-processing of system information where operational data of interest is flagged, and the like.

In embodiments, a monitoring application 8776 on a remote server 8774 may receive and store one or more of detection values, timing signals and data coming from a plurality of the various monitoring devices 8768. The monitoring application 8776 may then select subsets of the detection values, timing signals and data to be jointly analyzed. Subsets for analysis may be selected based on a single type of component or a single type of equipment in which a component is operating. Subsets for analysis may be selected or grouped based on common operating conditions such as size of load, operational condition (e.g., intermittent, continuous, process stage), operating speed or tachometer, common ambient environmental conditions such as humidity, temperature, air or fluid particulate, and the like. Subsets for analysis may be selected based on the effects of other nearby equipment such as nearby machines rotating at similar frequencies.
The monitoring application 8776 may then analyze the selected subset. In an illustrative example, data from a single component may be analyzed over different time periods such as one operating cycle, several operating cycles, a month, a year, the life of the component or the like. Data from multiple components of the same type may also be analyzed over different time periods. Trends in the data such as changes in frequency or amplitude may be correlated with failure and maintenance records associated with the same or a related component or piece of equipment. Trends in the data such as changing rates of change associated with start-up or different points in the process may be identified. Additional data may be introduced into the analysis such as output product quality, indicated success or failure of a process, and the like. Correlation of trends and values for different types of data may be analyzed to identify those parameters whose short-term analysis might provide the best prediction regarding expected performance. This information may be transmitted back to the monitoring device to update types of data collected and analyzed locally or to influence the design of future monitoring devices.
In an illustrative and non-limiting example, a monitoring device 8768 may be used to collect and process sensor data to measure mechanical torque. The monitoring device 8768 may be in communication with or include a high resolution, high speed vibration sensor to collect data over a period of time sufficient to measure multiple cycles of rotation. For gear driven components, the sampling resolution of the sensor should be such that the number of samples taken per cycle is at least equal to the number of gear teeth driving the component. It will be understood that a lower sampling resolution may also be utilized, which may result in a lower confidence determination and/or taking data over a longer period of time to develop sufficient statistical confidence. This data may then be used in the generation of a phase reference (relative probe) or tachometer signal for a piece of equipment. This phase reference may be used directly or used by the timer circuit 8714 to generate a timing signal to align phase data such as vibrational data or acceleration data from multiple sensors located at different positions on a component or on different components within a system. This information may facilitate the determination of torque for different components or the generation of an Operational Deflection Shape (ODS).
A higher resolution data stream may also provide additional data for the detection of transitory signals in low speed operations. The identification of transitory signals may enable the identification of defects in a piece of equipment or component operating a low RPMs.
In an illustrative and non-limiting example, the monitoring device may be used to identify mechanical jitter for use in failure prediction models. The monitoring device may begin acquiring data when the piece of equipment starts up, through ramping up to operating speed, and then during operation. Once at operating speed, it is anticipated that the torsional jitter should be minimal or within expected ranges, and changes in torsion during this phase may be indicative of cracks, bearing faults, and the like. Additionally, known torsions may be removed from the signal to facilitate in the identification of unanticipated torsions resulting from system design flaws, component wear, or unexpected process events. Having phase information associated with the data collected at operating speed may facilitate identification of a location of vibration and potential component wear, and/or may be further correlated to a type of failure for a component. Relative phase information for a plurality of sensors located throughout a machine may facilitate the evaluation of torsion as it is propagated through a piece of equipment.
In embodiments, the monitoring application 8776 may have access to equipment specifications, equipment geometry, component specifications, component materials, anticipated state information for plurality of component types, operational history, historical detection values, component life models, and the like for use in analyzing the selected subset using rule-based or model-based analysis. In embodiments, the monitoring application 8776 may feed a neural net with the selected subset to learn to recognize various operating state, health states (e.g., lifetime predictions) and fault states utilizing deep learning techniques. In embodiments, a hybrid of the two techniques (model-based learning and deep learning) may be used.

In embodiments, information about the health or other status or state information of or regarding a component or piece of industrial equipment may be obtained by monitoring the condition of various components throughout a process. Monitoring may include monitoring the amplitude of a sensor signal measuring attributes such as temperature, humidity, acceleration, displacement and the like. An embodiment of a data monitoring device 9000 is shown in
The plurality of sensors 9006 may be wired to ports on the data acquisition circuit 9004. The plurality of sensors 9006 may be wirelessly connected to the data acquisition circuit 9004. The data acquisition circuit 9004 may be able to access detection values corresponding to the output of at least one of the plurality of sensors 9006 where the sensors 9006 may be capturing data on different operational aspects of a piece of equipment or an operating component.
The selection of the plurality of sensors 9006 for a data monitoring device 9000 designed for a specific component or piece of equipment may depend on a variety of considerations such as accessibility for installing new sensors, incorporation of sensors in the initial design, anticipated operational and failure conditions, resolution desired at various positions in a process or plant, reliability of the sensors, power availability, power utilization, storage utilization, and the like. The impact of a failure, time response of a failure (e.g., warning time and/or off-optimal modes occurring before failure), likelihood of failure, extent of impact of failure, and/or sensitivity required and/or difficulty to detection failure conditions may drive the extent to which a component or piece of equipment is monitored with more sensors and/or higher capability sensors being dedicated to systems where unexpected or undetected failure would be costly or have severe consequences.
The signal evaluation circuit 9008 may process the detection values to obtain information about a component or piece of equipment being monitored. Information extracted by the signal evaluation circuit 9008 may comprise information regarding a peak value of a signal such as a peak temperature, peak acceleration, peak velocity, peak pressure, peak weight bearing, peak strain, peak bending, or peak displacement. The peak detection may be done using analog or digital circuits. In embodiments, the peak detection circuit 9012 may be able to distinguish between “local” or short term peaks in a stream of detection values and a “global” or longer term peak. In embodiments, the peak detection circuit 9012 may be able to identify peak shapes (not just a single peak value) such as flat tops, asymptotic approaches, discrete jumps in the peak value or rapid/steep climbs in peak value, sinusoidal behavior within ranges and the like. Flat topped peaks may indicate saturation at of a sensor. Asymptotic approaches to a peak may indicate linear system behavior. Discrete jumps in value or steep changes in peak value may indicate quantized or nonlinear behavior of either the sensor doing the measurement or the behavior of the component. In embodiments, the system may be able to identify sinusoidal variations in the peak value within an envelope, such as an envelope established by line or curve connecting a series of peak values. It should be noted that references to “peaks” should be understood to encompass one or more “valleys,” representing a series of low points in measurement, except where context indicates otherwise.
In embodiments, a peak value may be used as a reference for an analog-to-digital conversion circuit 9014.
In an illustrative and non-limiting example, a temperature probe may measure the temperature of a gear as it rotates in a machine. The peak temperature may be detected by a peak detection circuit 9012. The peak temperature may be fed into an analog-to-digital converter circuit 9014 to appropriately scale a stream of detection values corresponding to temperature readings of the gear as it rotates in a machine. The phase of the stream of detection values corresponding to temperature relative to an orientation of the gear may be determined by the phase detection circuit 9016. Knowing where in the rotation of the gear a peak temperature is occurring may allow the identification of a bad gear tooth.
In some embodiments, two or more sets of detection values may be fused to create detection values for a virtual sensor. A peak detection circuit may be used to verify consistency in timing of peak values between at least one of the two or more sets of detection values and the detection values for the virtual sensor.
In embodiments, the signal evaluation circuit 9008 may be able to reset the peak detection circuit 9012 upon start-up of the monitoring device 9000, upon edge detection of a control signal of the system being monitored, based on a user input, after a system error and the like. In embodiments, the signal evaluation circuit 9008 may discard an initial portion of the output of the peak detection circuit 9012 prior to using the peak value as a reference value for an analog-to-digital conversion circuit to allow the system to fully come on line.
Depending on the type of equipment, the component being measured, the environment in which the equipment is operating and the like, sensors 9006 may comprise one or more of, without limitation, a vibration sensor, a thermometer, a hygrometer, a voltage sensor, a current sensor, an accelerometer, a velocity detector, a light or electromagnetic sensor (e.g., determining temperature, composition and/or spectral analysis, and/or object position or movement), an image sensor, a structured light sensor, a laser-based image sensor, an acoustic wave sensor, a displacement sensor, a turbidity meter, a viscosity meter, a load sensor, a tri-axial sensor, an accelerometer, a tachometer, a fluid pressure meter, an air flow meter, a horsepower meter, a flow rate meter, a fluid particle detector, an acoustical sensor, a pH sensor, and the like, including, without limitation, any of the sensors described throughout this disclosure and the documents incorporated by reference.
The sensors 9006 may provide a stream of data over time that has a phase component, such as relating to acceleration or vibration, allowing for the evaluation of phase or frequency analysis of different operational aspects of a piece of equipment or an operating component. The sensors 9006 may provide a stream of data that is not conventionally phase-based, such as temperature, humidity, load, and the like. The sensors 9006 may provide a continuous or near continuous stream of data over time, periodic readings, event-driven readings, and/or readings according to a selected interval or schedule.

In embodiments, the response circuit 9710 may initiate a variety of actions based on the sensor status provided by the overload detection circuit 9712. The response circuit 9710 may continue using the sensor if the sensor status is “sensor healthy.” The response circuit 9710 may adjust a sensor scaling value (e.g., from 100 mV/gram to 10 mV/gram). The response circuit 9710 may increase an acquisition range for an alternate sensor. The response circuit 9710 may back sensor data out of previous calculations and evaluations such as bearing analysis, torsional analysis and the like. The response circuit 9710 may use projected or anticipated data (based on data acquired prior to overload/failure) in place of the actual sensor data for calculations and evaluations such as bearing analysis, torsional analysis and the like. The response circuit 9710 may issue an alarm. The response circuit 9710 may issue an alert that may comprise notification that the sensor is out of range together with information regarding the extent of the overload such as “overload range—data response may not be reliable and/or linear”, “destructive range—sensor may be damaged,” and the like. The response circuit 9710 may issue an alert where the alert may comprise information regarding the effect of sensor load such as “unable to monitor machine health” due to sensor overload/failure,” and the like.
In embodiments, the response circuit 9710 may cause the data acquisition circuit 9704 to enable or disable the processing of detection values corresponding to certain sensors based on the sensor statues described above. This may include switching to sensors having different response rates, sensitivity, ranges, and the like; accessing new sensors or types of sensors, accessing data from multiple sensors, recruiting additional data collectors (such as routing the collectors to a point of work, using routing methods and systems disclosed throughout this disclosure and the documents incorporated by reference) and the like. Switching may be undertaken based on a model, a set of rules, or the like. In embodiments, switching may be under control of a machine learning system, such that switching is controlled based on one or more metrics of success, combined with input data, over a set of trials, which may occur under supervision of a human supervisor or under control of an automated system. Switching may involve switching from one input port to another (such as to switch from one sensor to another). Switching may involve altering the multiplexing of data, such as combining different streams under different circumstances. Switching may involve activating a system to obtain additional data, such as moving a mobile system (such as a robotic or drone system), to a location where different or additional data is available (such as positioning an image sensor for a different view or positioning a sonar sensor for a different direction of collection) or to a location where different sensors can be accessed (such as moving a collector to connect up to a sensor that is disposed at a location in an environment by a wired or wireless connection). This switching may be implemented by changing the control signals for a multiplexor circuit 9731 and/or by turning on or off certain input sections of the multiplexor circuit 9731.
In embodiments, the response circuit 9710 may make recommendations for the replacement of certain sensors in the future with sensors having different response rates, sensitivity, ranges, and the like. The response circuit 9710 may recommend design alterations for future embodiments of the component, the piece of equipment, the operating conditions, the process, and the like.
In embodiments, the response circuit 9710 may recommend maintenance at an upcoming process stop or initiate a maintenance call where the maintenance may include the replacement of the sensor with the same or an alternate type of sensor having a different response rate, sensitivity, range and the like. In embodiments, the response circuit 9710 may implement or recommend process changes—for example to lower the utilization of a component that is near a maintenance interval, operating off-nominally, or failed for purpose but still at least partially operational, to change the operating speed of a component (such as to put it in a lower-demand mode), to initiate amelioration of an issue (such as to signal for additional lubrication of a roller bearing set, or to signal for an alignment process for a system that is out of balance), and the like.
In embodiments, the signal evaluation circuit 9708 and/or the response circuit 9710 may periodically store certain detection values in the data storage circuit 9716 to enable the tracking of component performance over time. In embodiments, based on sensor status, as described elsewhere herein recently measured sensor data and related operating conditions such as RPMs, component loads, temperatures, pressures, vibrations or other sensor data of the types described throughout this disclosure in the data storage circuit 9716 to enable the backing out of overloaded/failed sensor data. The signal evaluation circuit 9708 may store data at a higher data rate for greater granularity in future processing, the ability to reprocess at different sampling rates, and/or to enable diagnosing or post-processing of system information where operational data of interest is flagged, and the like.

In the cloud platform, optionally using massively parallel computational capability, a plurality of different neural networks of several types (including modular forms, structure-adaptive forms, hybrids, and the like) may be used to undertake prediction, classification, control functions, and provide other outputs as described in connection with expert systems disclosed throughout this disclosure. The different neural networks may be structured to compete with each other (optionally including the use of evolutionary algorithms, genetic algorithms, or the like), such that an appropriate type of neural network, with appropriate input sets, weights, node types and functions, and the like, may be selected, such as by an expert system, for a specific task involved in a given context, workflow, environment process, system, or the like.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a feed forward neural network, which moves information in one direction, such as from a data input, like an analog sensor located on or proximal to an industrial machine, through a series of neurons or nodes, to an output. Data may move from the input nodes to the output nodes, optionally passing through one or more hidden nodes, without loops. In embodiments, feedforward neural networks may be constructed with various types of units, such as binary McCulloch-Pitts neurons, the simplest of which is a perceptron.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a radial basis function (RBF) neural network, which may be preferred in some situations involving interpolation in a multi-dimensional space (such as where interpolation is helpful in optimizing a multi-dimensional function, such as for optimizing a data marketplace as described here, optimizing the efficiency or output of a power generation system, a factory system, or the like, or other situation involving multiple dimensions). In embodiments, each neuron in the RBF neural network stores an example from a training set as a “prototype.” Linearity involved in the functioning of this neural network offers RBF the advantage of not typically suffering from problems with local minima or maxima.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a radial basis function (RBF) neural network, such as one that employs a distance criterion with respect to a center (e.g., a Gaussian function). A radial basis function may be applied as a replacement for a hidden layer (such as a sigmoidal hidden layer transfer) in a multi-layer perceptron. An RBF network may have two layers, such as the case where an input is mapped onto each RBF in a hidden layer. In embodiments, an output layer may comprise a linear combination of hidden layer values representing, for example, a mean predicted output. The output layer value may provide an output that is the same as or similar to that of a regression model in statistics. In classification problems, the output layer may be a sigmoid function of a linear combination of hidden layer values, representing a posterior probability. Performance in both cases is often improved by shrinkage techniques, such as ridge regression in classical statistics. This corresponds to a prior belief in small parameter values (and therefore smooth output functions) in a Bayesian framework. RBF networks may avoid local minima, because the only parameters that are adjusted in the learning process are the linear mapping from hidden layer to output layer. Linearity ensures that the error surface is quadratic and therefore has a single minimum. In regression problems, this can be found in one matrix operation. In classification problems, the fixed non-linearity introduced by the sigmoid output function may be handled using an iteratively re-weighted least squares function or the like.
RBF networks may use kernel methods such as support vector machines (SVM) and Gaussian processes (where the RBF is the kernel function). A non-linear kernel function may be used to project the input data into a space where the learning problem can be solved using a linear model.
In embodiments, an RBF neural network may include an input layer, a hidden layer, and a summation layer. In the input layer, one neuron appears in the input layer for each predictor variable. In the case of categorical variables, N−1 neurons are used, where N is the number of categories. The input neurons may, in embodiments, standardize the value ranges by subtracting the median and dividing by the interquartile range. The input neurons may then feed the values to each of the neurons in the hidden layer. In the hidden layer, a variable number of neurons may be used (determined by the training process). Each neuron may consist of a radial basis function that is centered on a point with as many dimensions as a number of predictor variables. The spread (e.g., radius) of the RBF function may be different for each dimension. The centers and spreads may be determined by training. When presented with a vector of input values from the input layer, a hidden neuron may compute a Euclidean distance of the test case from the neuron's center point and then apply the RBF kernel function to this distance, such as using the spread values. The resulting value may then be passed to the summation layer. In the summation layer, the value coming out of a neuron in the hidden layer may be multiplied by a weight associated with the neuron and may add to the weighted values of other neurons. This sum becomes the output. For classification problems, one output is produced (with a separate set of weights and summation units) for each target category. The value output for a category is the probability that the case being evaluated has that category. In training of an RBF, various parameters may be determined, such as the number of neurons in a hidden layer, the coordinates of the center of each hidden-layer function, the spread of each function in each dimension, and the weights applied to outputs as they pass to the summation layer. Training may be used by clustering algorithms (such as k-means clustering), by evolutionary approaches, and the like.
In embodiments, a recurrent neural network may have a time-varying, real-valued (more than just zero or one) activation (output). Each connection may have a modifiable real-valued weight. Some of the nodes are called labeled nodes, some output nodes, and others hidden nodes. For supervised learning in discrete time settings, training sequences of real-valued input vectors may become sequences of activations of the input nodes, one input vector at a time. At each time step, each non-input unit may compute its current activation as a nonlinear function of the weighted sum of the activations of all units from which it receives connections. The system can explicitly activate (independent of incoming signals) some output units at certain time steps.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a self-organizing neural network, such as a Kohonen self-organizing neural network, such as for visualization of views of data, such as low-dimensional views of high-dimensional data. The self-organizing neural network may apply competitive learning to a set of input data, such as from one or more sensors or other data inputs from or associated with an industrial machine. In embodiments, the self-organizing neural network may be used to identify structures in data, such as unlabeled data, such as in data sensed from a range of vibration, acoustic, or other analog sensors in an industrial environment, where sources of the data are unknown (such as where vibrations may be coming from any of a range of unknown sources). The self-organizing neural network may organize structures or patterns in the data, such that they can be recognized, analyzed, and labeled, such as identifying structures as corresponding to vibrations induced by the movement of a floor, or acoustic signals created by high frequency rotation of a shaft of a somewhat distant machine.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a recurrent neural network, which may allow for a bi-directional flow of data, such as where connected units (e.g., neurons or nodes) form a directed cycle. Such a network may be used to model or exhibit dynamic temporal behavior, such as those involved in dynamic systems including a wide variety of the industrial machines and devices described throughout this disclosure, such as a power generation machine operating at variable speeds or frequencies in variable conditions with variable inputs, a robotic manufacturing system, a refining system, or the like, where dynamic system behavior involves complex interactions that an operator may desire to understand, predict, control and/or optimize. For example, the recurrent neural network may be used to anticipate the state (such as a maintenance state, a fault state, an operational state, or the like), of an industrial machine, such as one performing a dynamic process or action. In embodiments, the recurrent neural network may use internal memory to process a sequence of inputs, such as from other nodes and/or from sensors and other data inputs from the industrial environment, of the various types described herein. In embodiments, the recurrent neural network may also be used for pattern recognition, such as for recognizing an industrial machine based on a sound signature, a heat signature, a set of feature vectors in an image, a chemical signature, or the like. In a non-limiting example, a recurrent neural network may recognize a shift in an operational mode of a turbine, a generator, a motor, a compressor, or the like (such as a gear shift) by learning to classify the shift from a training data set consisting of a stream of data from tri-axial vibration sensors and/or acoustic sensors applied to one or more of such machines.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a modular neural network, which may comprise a series of independent neural networks (such as ones of various types described herein) that are moderated by an intermediary. Each of the independent neural networks in the modular neural network may work with separate inputs, accomplishing subtasks that make up the task the modular network as whole is intended to perform. For example, a modular neural network may comprise a recurrent neural network for pattern recognition, such as to recognize what type of industrial machine is being sensed by one or more sensors that are provided as input channels to the modular network and an RBF neural network for optimizing the behavior of the machine once understood. The intermediary may accept inputs of each of the individual neural networks, process them, and create output for the modular neural network, such an appropriate control parameter, a prediction of state, or the like.
Combinations among any of the pairs, triplets, or larger combinations, of the various neural network types described herein, are encompassed by the present disclosure. This may include combinations where an expert system uses one neural network for recognizing a pattern (e.g., a pattern indicating a problem or fault condition) and a different neural network for self-organizing an activity or work flow based on the recognized pattern (such as providing an output governing autonomous control of a system in response to the recognized condition or pattern). This may also include combinations where an expert system uses one neural network for classifying an item (e.g., identifying a machine, a component, or an operational mode) and a different neural network for predicting a state of the item (e.g., a fault state, an operational state, an anticipated state, a maintenance state, or the like). Modular neural networks may also include situations where an expert system uses one neural network for determining a state or context (such as a state of a machine, a process, a work flow, a marketplace, a storage system, a network, a data collector, or the like) and a different neural network for self-organizing a process involving the state or context (e.g., a data storage process, a network coding process, a network selection process, a data marketplace process, a power generation process, a manufacturing process, a refining process, a digging process, a boring process, or other process described herein).
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a physical neural network where one or more hardware elements is used to perform or simulate neural behavior. In embodiments, one or more hardware neurons may be configured to stream voltage values that represent analog vibration sensor data voltage values, to calculate velocity information from analog sensor inputs representing acoustic, vibration or other data, to calculation acceleration information from sensor inputs representing acoustic, vibration, or other data, or the like. One or more hardware nodes may be configured to stream output data resulting from the activity of the neural net. Hardware nodes, which may comprise one or more chips, microprocessors, integrated circuits, programmable logic controllers, application-specific integrated circuits, field-programmable gate arrays, or the like, may be provided to optimize the speed, input/output efficiency, energy efficiency, signal to noise ratio, or other parameter of some part of a neural net of any of the types described herein. Hardware nodes may include hardware for acceleration of calculations (such as dedicated processors for performing basic or more sophisticated calculations on input data to provide outputs, dedicated processors for filtering or compressing data, dedicated processors for decompressing data, dedicated processors for compression of specific file or data types (e.g., for handling image data, video streams, acoustic signals, vibration data, thermal images, heat maps, or the like), and the like. A physical neural network may be embodied in a data collector, such as a mobile data collector described herein, including one that may be reconfigured by switching or routing inputs in varying configurations, such as to provide different neural net configurations within the data collector for handling different types of inputs (with the switching and configuration optionally under control of an expert system, which may include a software-based neural net located on the data collector or remotely). A physical, or at least partially physical, neural network may include physical hardware nodes located in a storage system, such as for storing data within an industrial machine or in an industrial environment, such as for accelerating input/output functions to one or more storage elements that supply data to or take data from the neural net. A physical, or at least partially physical, neural network may include physical hardware nodes located in a network, such as for transmitting data within, to or from an industrial environment, such as for accelerating input/output functions to one or more network nodes in the net, accelerating relay functions, or the like. In embodiments of a physical neural network, an electrically adjustable resistance material may be used for emulating the function of a neural synapse. In embodiments, the physical hardware emulates the neurons, and software emulates the neural network between the neurons. In embodiments, neural networks complement conventional algorithmic computers. They are versatile and can be trained to perform appropriate functions without the need for any instructions, such as classification functions, optimization functions, pattern recognition functions, control functions, selection functions, evolution functions, and others.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a multilayered feed forward neural network, such as for complex pattern classification of one or more items, phenomena, modes, states, or the like. In embodiments, a multilayered feedforward neural network may be trained by an optimization technical, such as a genetic algorithm, such as to explore a large and complex space of options to find an optimum, or near-optimum, global solution. For example, one or more genetic algorithms may be used to train a multilayered feedforward neural network to classify complex phenomena, such as to recognize complex operational modes of industrial machines, such as modes involving complex interactions among machines (including interference effects, resonance effects, and the like), modes involving non-linear phenomena, such as impacts of variable speed shafts, which may make analysis of vibration and other signals difficult, modes involving critical faults, such as where multiple, simultaneous faults occur, making root cause analysis difficult, and others. In embodiments, a multilayered feed forward neural network may be used to classify results from ultrasonic monitoring or acoustic monitoring of an industrial machine, such as monitoring an interior set of components within a housing, such as motor components, pumps, valves, fluid handling components, and many others, such as in refrigeration systems, refining systems, reactor systems, catalytic systems, and others.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a feedforward, back-propagation multi-layer perceptron (MLP) neural network, such as for handling one or more remote sensing applications, such as for taking inputs from sensors distributed throughout various industrial environments. In embodiments, the MLP neural network may be used for classification of physical environments, such as mining environments, exploration environments, drilling environments, and the like, including classification of geological structures (including underground features and above ground features), classification of materials (including fluids, minerals, metals, and the like), and other problems. This may include fuzzy classification.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a structure-adaptive neural network, where the structure of a neural network is adapted, such as based on a rule, a sensed condition, a contextual parameter, or the like. For example, if a neural network does not converge on a solution, such as classifying an item or arriving at a prediction, when acting on a set of inputs after some amount of training, the neural network may be modified, such as from a feedforward neural network to a recurrent neural network, such as by switching data paths between some subset of nodes from unidirectional to bi-directional data paths. The structure adaptation may occur under control of an expert system, such as to trigger adaptation upon occurrence of a trigger, rule or event, such as recognizing occurrence of a threshold (such as an absence of a convergence to a solution within a given amount of time) or recognizing a phenomenon as requiring different or additional structure (such as recognizing that a system is varying dynamically or in a non-linear fashion). In one non-limiting example, an expert system may switch from a simple neural network structure like a feedforward neural network to a more complex neural network structure like a recurrent neural network, a convolutional neural network, or the like upon receiving an indication that a continuously variable transmission is being used to drive a generator, turbine, or the like in a system being analyzed.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use an autoencoder, autoassociator or Diabolo neural network, which may be similar to a multilayer perceptron (“MLP”) neural network, such as where there may be an input layer, an output layer and one or more hidden layers connecting them. However, the output layer in the auto-encoder may have the same number of units as the input layer, where the purpose of the MLP neural network is to reconstruct its own inputs (rather than just emitting a target value). Therefore, the auto encoders may operate as an unsupervised learning model. An auto encoder may be used, for example, for unsupervised learning of efficient codings, such as for dimensionality reduction, for learning generative models of data, and the like. In embodiments, an auto-encoding neural network may be used to self-learn an efficient network coding for transmission of analog sensor data from an industrial machine over one or more networks. In embodiments, an auto-encoding neural network may be used to self-learn an efficient storage approach for storage of streams of analog sensor data from an industrial environment.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a probabilistic neural network (“PNN”), which in embodiments may comprise a multi-layer (e.g., four-layer) feedforward neural network, where layers may include input layers, hidden layers, pattern/summation layers and an output layer. In an embodiment of a PNN algorithm, a parent probability distribution function (PDF) of each class may be approximated, such as by a Parzen window and/or a non-parametric function. Then, using the PDF of each class, the class probability of a new input is estimated, and Bayes' rule may be employed, such as to allocate it to the class with the highest posterior probability. A PNN may embody a Bayesian network and may use a statistical algorithm or analytic technique, such as Kernel Fisher discriminant analysis technique. The PNN may be used for classification and pattern recognition in any of a wide range of embodiments disclosed herein. In one non-limiting example, a probabilistic neural network may be used to predict a fault condition of an engine based on collection of data inputs from sensors and instruments for the engine.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a time delay neural network (TDNN), which may comprise a feedforward architecture for sequential data that recognizes features independent of sequence position. In embodiments, to account for time shifts in data, delays are added to one or more inputs, or between one or more nodes, so that multiple data points (from distinct points in time) are analyzed together. A time delay neural network may form part of a larger pattern recognition system, such as using a perceptron network. In embodiments, a TDNN may be trained with supervised learning, such as where connection weights are trained with back propagation or under feedback. In embodiments, a TDNN may be used to process sensor data from distinct streams, such as a stream of velocity data, a stream of acceleration data, a stream of temperature data, a stream of pressure data, and the like, where time delays are used to align the data streams in time, such as to help understand patterns that involve understanding of the various streams (e.g., where increases in pressure and acceleration occur as an industrial machine overheats).
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a convolutional neural network (referred to in some cases as a CNN, a ConvNet, a shift invariant neural network, or a space invariant neural network), wherein the units are connected in a pattern similar to the visual cortex of the human brain. Neurons may respond to stimuli in a restricted region of space, referred to as a receptive field. Receptive fields may partially overlap, such that they collectively cover the entire (e.g., visual) field. Node responses can be calculated mathematically, such as by a convolution operation, such as using multilayer perceptron that use minimal preprocessing. A convolutional neural network may be used for recognition within images and video streams, such as for recognizing a type of machine in a large environment using a camera system disposed on a mobile data collector, such as on a drone or mobile robot. In embodiments, a convolutional neural network may be used to provide a recommendation based on data inputs, including sensor inputs and other contextual information, such as recommending a route for a mobile data collector. In embodiments, a convolutional neural network may be used for processing inputs, such as for natural language processing of instructions provided by one or more parties involved in a workflow in an environment. In embodiments, a convolutional neural network may be deployed with a large number of neurons (e.g., 100,000, 500,000 or more), with multiple (e.g., 4, 5, 6 or more) layers, and with many (e.g., millions) parameters. A convolutional neural net may use one or more convolutional nets.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a regulatory feedback network, such as for recognizing emergent phenomena (such as new types of faults not previously understood in an industrial environment).
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a self-organizing map (“SOM”), involving unsupervised learning. A set of neurons may learn to map points in an input space to coordinates in an output space. The input space can have different dimensions and topology from the output space, and the SOM may preserve these while mapping phenomena into groups.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a learning vector quantization neural net (“LVQ”). Prototypical representatives of the classes may parameterize, together with an appropriate distance measure, in a distance-based classification scheme.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use an echo state network (“ESN”), which may comprise a recurrent neural network with a sparsely connected, random hidden layer. The weights of output neurons may be changed (e.g., the weights may be trained based on feedback). In embodiments, an ESN may be used to handle time series patterns, such as, in an example, recognizing a pattern of events associated with a gear shift in an industrial turbine, generator, or the like.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a bi-directional, recurrent neural network (“BRNN”), such as using a finite sequence of values (e.g., voltage values from a sensor) to predict or label each element of the sequence based on both the past and the future context of the element. This may be done by adding the outputs of two RNNs, such as one processing the sequence from left to right, the other one from right to left. The combined outputs are the predictions of target signals, such as those provided by a teacher or supervisor. A bi-directional RNN may be combined with a long short-term memory RNN.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a hierarchical RNN that connects elements in various ways to decompose hierarchical behavior, such as into useful subprograms. In embodiments, a hierarchical RNN may be used to manage one or more hierarchical templates for data collection in an industrial environment.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a stochastic neural network, which may introduce random variations into the network. Such random variations can be viewed as a form of statistical sampling, such as Monte Carlo sampling.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a genetic scale recurrent neural network. In such embodiments, a RNN (often a LS™) is used where a series is decomposed into a number of scales where every scale informs the primary length between two consecutive points. A first order scale consists of a normal RNN, a second order consists of all points separated by two indices and so on. The Nth order RNN connects the first and last node. The outputs from all the various scales may be treated as a committee of members, and the associated scores may be used genetically for the next iteration.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a committee of machines (“CoM”), comprising a collection of different neural networks that together “vote” on a given example. Because neural networks may suffer from local minima, starting with the same architecture and training, but using randomly different initial weights often gives different results. A CoM tends to stabilize the result.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use an associative neural network (“ASNN”), such as involving an extension of committee of machines that combines multiple feed forward neural networks and a k-nearest neighbor technique. It may use the correlation between ensemble responses as a measure of distance amid the analyzed cases for the kNN. This corrects the bias of the neural network ensemble. An associative neural network may have a memory that can coincide with a training set. If new data become available, the network instantly improves its predictive ability and provides data approximation (self-learns) without retraining. Another important feature of ASNN is the possibility to interpret neural network results by analysis of correlations between data cases in the space of models.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use an instantaneously trained neural network (“ITNN”), where the weights of the hidden and the output layers are mapped directly from training vector data.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a spiking neural network, which may explicitly consider the timing of inputs. The network input and output may be represented as a series of spikes (such as a delta function or more complex shapes). SNNs can process information in the time domain (e.g., signals that vary over time, such as signals involving dynamic behavior of industrial machines). They are often implemented as recurrent networks.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a dynamic neural network that addresses nonlinear multivariate behavior and includes learning of time-dependent behavior, such as transient phenomena and delay effects. Transients may include behavior of shifting industrial components, such as variable speeds of rotating shafts or other rotating components.
In embodiments, cascade correlation may be used as an architecture and supervised learning algorithm, supplementing adjustment of the weights in a network of fixed topology. Cascade-correlation may begin with a minimal network, then automatically trains and adds new hidden units one by one, creating a multi-layer structure. Once a new hidden unit has been added to the network, its input-side weights may be frozen. This unit then becomes a permanent feature-detector in the network, available for producing outputs or for creating other, more complex feature detectors. The cascade-correlation architecture may learn quickly, determine its own size and topology, and retain the structures it has built even if the training set changes and requires no back-propagation.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a neuro-fuzzy network, such as involving a fuzzy inference system in the body of an artificial neural network. Depending on the type, several layers may simulate the processes involved in a fuzzy inference, such as fuzzification, inference, aggregation and defuzzification. Embedding a fuzzy system in a general structure of a neural net as the benefit of using available training methods to find the parameters of a fuzzy system.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a compositional pattern-producing network (“CPPN”), such as a variation of an associative neural network (“ANN”) that differs the set of activation functions and how they are applied. While typical ANNs often contain only sigmoid functions (and sometimes Gaussian functions), CPPNs can include both types of functions and many others. Furthermore, CPPNs may be applied across the entire space of possible inputs, so that they can represent a complete image. Since they are compositions of functions, CPPNs in effect encode images at infinite resolution and can be sampled for a particular display at whatever resolution is optimal.
This type of network can add new patterns without re-training. In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a one-shot associative memory network, such as by creating a specific memory structure, which assigns each new pattern to an orthogonal plane using adjacently connected hierarchical arrays.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a hierarchical temporal memory (“HTM”) neural network, such as involving the structural and algorithmic properties of the neocortex. HTM may use a biomimetic model based on memory-prediction theory. HTM may be used to discover and infer the high-level causes of observed input patterns and sequences.
In embodiments, methods and systems described herein that involve an expert system or self-organization capability may use a holographic associative memory (“HAM”) neural network, which may comprise an analog, correlation-based, associative, stimulus-response system. Information may be mapped onto the phase orientation of complex numbers. The memory is effective for associative memory tasks, generalization and pattern recognition with changeable attention.
In embodiments, various embodiments involving network coding may be used to code transmission data among network nodes in neural net, such as where nodes are located in one or more data collectors or machines in an industrial environment.

A system, comprising: a network coding system for coding transmission of data among network nodes in neural network, wherein the nodes comprise hardware devices located in at least one of one or more data collectors, one or more storage systems, and one or more network devices located in an industrial environment.
Within the data collection, monitoring, and control environment of the industrial IoT are large and various sensor sets, which make efficient setup and timely changes to sensor data collection a challenge. Continuous collection from all sensors may be impossible given the large number of sensors and limited resources, such as limited availability of power and limited data collection and management facilities, including various limitations in availability and performance of sensor data collection devices, input/output interfaces, data transfer facilities, data storage, data analysis facilities, and the like. The number of sensors collected from at any given time must therefore be limited in an intelligent but timely manner, both at the time of setting up initial collection and during the process of collection, including handling rapid changes to a present collection scheme based on a change in state of a system, operational conditions (e.g., an alert condition, change in operational mode, etc.), or the like. Embodiments of the methods and systems disclosed herein may therefore include rapid route creation and modification for routing collectors, such as by taking advantage of hierarchical templates, execution of smart route changes, monitoring and responding to changes in operational conditions, and the like.
In embodiments, rapid route creation and modification for data collection in an industrial environment may take advantage of hierarchical templates. Templates may be used to take advantage of ‘like’ machinery that can utilize the same hierarchical sensor routing scheme. For example, among many possible types of machines about which data may be collected, the members of a certain class of motor, such as a stepper motor class, may have very similar sensor routing needs, such as for routine operations, routine maintenance, and failure mode detection, that may be described in a common hierarchy of sensor collection routines. The user installing a new stepper motor may then use the ‘stepper motor hierarchical routing template’ for the new motor. After installation, the stepper motor hierarchical routing template may then be used to change the routing schemes for changing conditions. The user may optionally make adjustments to the template as needed per unique motor functions, applications, environments, modes, and the like. The use of a template for deploying a routing scheme greatly reduces the time a user requires to configure the routing scheme for a new motor, or to deploy new routing technologies on an existing system that utilizes traditional sensor collection methods. Once the hierarchical routing template is in place, the sensor collection routine may be changed quickly based on the template, thus allowing for rapid route modification under changing conditions, such as: a change in the operating mode of the stepper motor that requires a different subset of sensors for monitoring, a limit alert or failure indication that requires a more focused subset of sensors for use in diagnosing the problem, and the like. Hierarchical routing templates thus allow for rapid deployment of sensor routing configurations, as well as allowing the sensed industrial environment to be altered dynamically as conditions change.
A functional hierarchy of routing templates may include different hierarchical configurations for a component, machine, system, industrial environment, and the like, including all sensors and a plurality of configurations formed from a subset of all sensors. At a system level, an ‘all-sensor’ configuration may include: a connection map to all sensors in a system, mapping to all onboard instrumentation sensors (e.g., monitoring points reporting within a machine or set of machines), mapping to an environment's sensors (e.g., monitoring points around the machines/equipment, but not necessarily onboard), mapping to available sensors on data collectors (e.g., data collectors that can be flexibly provisioned for particular data among different kinds), a unified map combining different individual mappings, and the like. A routing configuration may be provided, such as to indicate how to implement an operational routing scheme, a scheduled maintenance routing scheme (e.g., collecting from a greater set of overall sensors than in operational mode, but distributed across the system, or a focused sensor set for specific components, functions, and modes), one or more failure mode routing schemes for multiple focused sensor collection groups targeting different failure mode analyses (e.g., for a motor, one failure mode may be for bearings, another for startup speed-torque, where a different subset of sensor data is needed based on the failure mode, such as detected in anomalous readings taken during operations or maintenance), power savings (e.g., weather conditions necessitating reduced plant power), and the like.
As noted, hierarchical templates may also be conditional (e.g., rule-based), such as templates with conditional routing based on parameters, such as sensed data during a first collection period, where a subsequent routing configuration is varied. Within the hierarchy, nodes in a graph or tree may indicate forks by which conditional logic may be used, such as to select a given subset of sensors for a given operational mode. Thus, the hierarchical template may be associated with a rule-based or model-based expert system, which may facilitate automated routing based on the hierarchical template and based on observed conditions, such as based on a type of machine and its operational state, environmental context, or the like. In a non-limiting example, a hierarchical template may have an initial collection configuration and a conditional hierarchy in place to switch from the initial collection configuration to a second collection configuration based on the sensed conditions of an initial sensor collection. Continuing this example, among various possible machines, a conveyor system may have a plurality of sensors for collection in an initial collection, but once the first data is collected and analyzed, if the conveyor is determined to be in an idle state (such as due to the absence of a signal above a minimum threshold on a motion sensor), then the system may switch to a sensor data collection regime that is appropriate for the idles state of the conveyor (e.g., using a very small subset of the plurality of sensors, such as just using the motion sensor to detect departure from the idle state, at which point the original regime may be renewed and the rest of a sensor set may be re-engaged). Thus, when the collection of sensor data detects a changed condition to a state, an operational mode, an environmental condition, or the like, the sensor data collection may be switched to an appropriate configuration.
Hierarchical templates for one collector may be based on coordination of routing with that of other collectors. For instance, a collector might be set up to perform vibration analysis while another collector is set up to perform pressure or temperature on each machine in a set of similar machines, rather than having each machine collect all of the data on each machine, where otherwise setup for different sensor types may be required for each collector for each machine. Factors such as the duration of sampling required, the time required to set up a given sensor, the amount of power consumed, the time available for collection as a whole, the data rate of input/output of a sensor and/or the collector, the bandwidth of a channel (wired or wireless) available for transmission of collected data, and the like can be considered in arranging the coordination of the routing of two or more collectors, such that various parallel and serial configurations may be undertaken to achieve an overall effectiveness. This may include optimizing the coordination using an expert system, such as a rule-based optimization, a model-based optimization, or optimization using machine learning.
A machine learning system may create a hierarchical template structure for improved routing, such as for teaching the system the default operating conditions (e.g., normal operations mode, systems online and average production), peak operations mode (max capability), slack production, and the like. The machine learning system may create a new hierarchical template based on monitored conditions, such as a template based on a production level profile, a rate of production profile, a detected failure mode pattern analysis, and the like. The application of a new machine learning created template may be based on a mode matching between current production conditions and a machine learning template condition (e.g., the machine learning system creates a new template for a new production profile, and applies that new template whenever that new profile is detected).
Rapid route creation may be enabled using one or more hierarchical routing templates, such as when a routing template pre-establishes a routing scheme for different conditions, and when a trigger event executes a change in the sensor routing scheme to accommodate the condition. In embodiments, the trigger event may be an automatic change in routing based on a trigger that indicates a possible failure mode that forces a change in routing scheme from operational to failure mode analysis; a human-executed change in routing scheme based on received sensor data; a learned routing change based on machine learning of when to trigger a change (e.g., as based on a machine being fed with a set of human-executed or human-supervised changes); a manual routing change (e.g., optional to automatic/rapid automatic change); a human executed change based on observed device performance; and the like. Routing changes may include: changing from an operational mode to an accelerated maintenance, a failure mode analysis, a power saving mode a high-performance/high-output mode (e.g., for peak power in a generation plant), and the like.
Switching hierarchical template configurations may be executed based on connectivity with end-device sensors. In a highly automated collection routing environment (e.g., an indoor networked assembly plant) different routing collection configurations may be employed for fixed and flexible industrial layouts. In a fixed industrial layout, such as a layout with a high degree of wired connectivity between end-device sensors, automated collectors, and networks, there may be different routing configurations for a network routing hierarchy portion, a collector sensor-collection hierarchy portion, a storage portion, and the like. For a more flexible industrial layout with various wired and wireless connections between end-device sensors, automated collectors, and networks, there may be different schemes. For instance, a moderately automated collection routing environment may include: automatic collection and periodic network connection; a robot-carried collector for periodic collection (e.g., a ground-based robot, a drone, an underwater device, a robot with network connection, a robot with intermittent network connection, a robot that periodically uploads collection); a routing scheme with periodic collection and automated routing; a scheme only collecting periodically but routed directly upon collection; a routing scheme with periodic collection and periodic automated routing to collect periodically; and, over longer periods of time, periodically routing multiple collections; and the like. For a lower degree of automated collection routing, there may be a combination of: automatic collection and human-aided collectors (e.g., humans collecting alone, humans aided by robots), scheduled collection and human-aided collectors (e.g., humans initiating collection, humans aided by robots for collection initiation, human launching a drone to collect data at a remote site), and the like.

In embodiments, the instructions may be deployed locally on the data collector, such as deployed in part locally on the data collector and in part on a remote information technology infrastructure component apart from the collector, where each of the input channels correspond to a sensor located in the environment.
Rapid route creation and modification in an industrial environment may employ smart route changes based on incoming data or alarms, such as changes enabling dynamic selection of data collection for analysis or correlation. Smart route changes may enable the system to alter current routing of sensor data based on incoming data or alarms. For instance, a user may set up a routing configuration that establishes a schedule of sensor collection for analysis, but when the analysis (or an alarm) indicates a special need, the system may change the sensor routing to address that need. For example, in the case where a change in a motor vibration profile (as one example among any of the machines described throughout this disclosure), such as rapidly increasing the peak amplitude of shaking on at least one axis of a vibration sensor set, that indicates a potential early failure of the motor, the system may change the routing to collect more focused data collection for analysis, such as initiating collection on more axes of the motor, initiating collection on additional bearings of the motor, and/or initiating collection using other sensors (such as temperature or heat flux sensors), that may confirm an initial hypothesis that the failure mode is occurring or otherwise assist in analysis of the state or operational condition of the machine.
Detected operational mode changes may trigger a rapid route change. For instance, an operational mode may be detected as the result of a single-point sensor out-of-range detection, an analysis determination, and the like, and generate a routing change. An analysis determination may be detected from a sensor end-point, such as through a single-point sensor analysis, a multiple-point sensor analysis, an analysis domain analysis (e.g., through a time profile, frequency profile, correlated multi-point determination), and the like. In another instance, a maintenance mode may be detected during routine maintenance, where a routing change increases data collection to capture data at a higher rate under an anomalous condition. A failure mode may be detected, such as through an alarm that indicates near-term potential for a failure of a machine that triggers increased data capture rate for analysis. Performance-based modes may be detected, such as detecting a level of output rate (e.g., peak, slack, idle), which may then initiate changes in routing to accommodate the analysis needs for the different performance monitoring and metrics associated with the state. For example, if a high peak speed is detected for a motor, a conveyor, an assembly line, a generator, a turbine, or the like, relative to historical measurements over some time period, additional sensors may be engaged to watch for failures that are typically associated with peak speeds, such as overheating (as measured by engaging a temperature or heat flux sensor), excessive noise (as measured by an acoustic or noise sensor), excessive shaking (as measured by one or more vibration sensors), or the like.
Alarm detections may trigger a rapid route change. Alarm sources may include a front-end collector, local intelligence resource, back-end data analysis process, ambient environment detector, network quality detector, power quality detector, heat, smoke, noise, flooding, and the like. Alarm types may include a single-instance anomaly detection, multiple-instance anomaly detection, simultaneous multi-sensor detection, time-clustered sensor detection (e.g., a single sensor or multiple sensors), frequency-profile detection (e.g., increasing rate of anomaly detection such as an alarm increasing in its occurrence over time, a change in a frequency component of a sensor output such as a motor's physical vibration profile changing over time), and the like.
A machine learning system may change routing based on learned alarm pattern analysis. The machine learning system may learn system alarm condition patterns, such as alarm conditions expected under normal operating conditions, under peak operating conditions, expected over time based on age of components (e.g., new, during operational life, during extended life, during a warrantee period), and the like. The machine learning system may change routing based on a change in an alarm pattern, such as a system operating normally but experiencing a peak operating alarm pattern (e.g., a system running when it should not be), a system is new but experiencing an older profile (e.g., detection of infant mortality), and the like. The machine learning system may change routing based on a current alarm profile vs. an expected change in production condition. For example, a plant, system, or component is experiencing above average alarm conditions just before a ramp-up of production (e.g., could be foretelling of above average failures during increased production), just before going slack (e.g., could be an opportunity to ramp up maintenance procedures based on increased data taking routing scheme), after an unplanned event (e.g., weather, power outage, restart), and the like.
A rapid route change action may include: an increased rate of sampling (e.g., to a single sensor, to multiple sensors), an increase in the number of sensors being sampled (e.g., simultaneous sampling of other sensors on a device, coordinated sampling of similar sensors on near-by devices), generating a burst of sampling (e.g., sampling at a high rate for a period of time), and the like. Actions may be executed on a schedule, coordinated with a trigger, based on an operational mode, and the like. Triggered actions may include: anomalous data, an exceeded threshold level, an operational event trigger (e.g., at startup condition such as for startup motor torque), and the like.
A rapid route change may switch between routing schemes, such as an operational routing scheme (e.g., a subset of sensor collection for normal operations), a scheduled maintenance routing scheme (e.g., an increased and focused set of sensor collection than for normal operations), and the like. The distribution of sensor data may be changed, such as to distribute sensor collection across the system, such as for a sensor collection set for specific components, functions, and modes. A failure mode routing scheme may entail multiple focused sensor collection groups targeting different failure mode analyses (e.g., for a motor, one failure mode may be for bearings, another for startup speed-torque) where a different subset of sensor data may be needed based on the failure mode (e.g., as detected in anomalous readings taken during operations or maintenance). Power saving mode routing may be executed when weather conditions necessitate reduced plant power.
Dynamic adjustment of route changes may be executed based on connectivity factors, such as the factors associated with the collector or network availability and bandwidth. For example, routing may be changed for a device associated with an alarm detection, where changing routing for targeted devices on the network frees up bandwidth. Changes to routing may have a duration, such as only for a pre-determined period of time and then switching back, maintaining a change until user-directed, changing duration based on network availability, and the like.

In embodiments, a system for data collection in an industrial environment may use ambient, local and vibration noise for prediction of outcomes, events, and states. A library may be populated with each of the three noise types for various conditions (e.g., start up, shut down, normal operation, other periods of operation as described elsewhere herein). In other embodiments, the library may be populated with noise patterns representing the aggregate ambient, local, and/or vibration noise. Analysis (e.g., filtering, signal conditioning, spectral analysis, trend analysis) may be performed on the aggregate noise to obtain a characteristic noise pattern and identify changes in noise pattern as possible indicators of a changed condition. A library of noise patterns may be generated with established vibration fingerprints and local and ambient noise that can be sorted by a parameter (see parameters herein), or other parameters/features of the local and ambient environment (e.g., company type, industry type, products, robotic handling unit present/not present, operating environment, flow rates, production rates, brand or type of auxiliary equipment (e.g., filters, seals, coupled machinery)). The library of noise patterns may be used by an expert system, such as one with machine learning capacity, to confirm a status of a machine, predict when maintenance is required (e.g., off-nominal measurement, artifacts in signal), predict a failure or an imminent failure, predict/diagnose a problem, and the like.
Based on a current noise pattern, the library may be consulted or used to seed an expert system to predict an outcome, event, or state based on the noise pattern. Based on the prediction, the expert system may one or more of trigger an alert of a failure, imminent failure, or maintenance event, shut down equipment/component/line, initiate maintenance/lubrication/alignment, deploy a field technician, recommend a vibration absorption/dampening device, modify a process to utilize backup equipment/component, modify a process to preserve products/reactants, etc., generate/modify a maintenance schedule, or the like.
For example, a noise pattern for a thermic heating system in a pharmaceutical plant or cooking system may include local, ambient, and vibration noise. The ambient noise may be a result of, for example, various pumps to pump fuel into the system. Local noise may be a result of a local security camera chirping with every detection of motion. Vibration noise may result from the combustion machinery used to heat the thermal fluid. These noise sources may form a noise pattern which may be associated with a state of the thermic system. The noise pattern and associated state may be stored in a library. An expert system used to monitor the state of the thermic heating system may be seeded with noise patterns and associated states from the library. As current data are received into the expert system, it may predict a state based on having learned noise patterns and associated states.
In another example, a noise pattern for boiler feed water in a refinery may include local and ambient noise. The local noise may be attributed to the operation of, for example, a feed pump feeding the feed water into a steam drum. The ambient noise may be attributed to nearby fans. These noise sources may form a noise pattern which may be associated with a state of the boiler feed water. The noise pattern and associated state may be stored in a library. An expert system used to monitor the state of the boiler may be seeded with noise patterns and associated states from the library. As current data are received into the expert system, it may predict a state based on having learned noise patterns and associated states.
In yet another example, a noise pattern for a storage tank in a refinery may include local, ambient, and vibration noise. The ambient noise may be a result of, for example, a pump that pumps a product into the tank. Local noise may be a result of a fan ventilating the tank room. Vibration noise may result from line noise of a power supply into the storage tank. These noise sources may form a noise pattern which may be associated with a state of the storage tank. The noise pattern and associated state may be stored in a library. An expert system used to monitor the state of the storage tank may be seeded with noise patterns and associated states from the library. As current data are received into the expert system, it may predict a state based on having learned noise patterns and associated states.
In another example, a noise pattern for condensate/make-up water system in a power station may include vibration and ambient noise. The ambient noise may be attributed to nearby fans. The vibration noise may be attributed to the operation of the condenser. These noise sources may form a noise pattern which may be associated with a state of the condensate/make-up water system. The noise pattern and associated state may be stored in a library. An expert system used to monitor the state of the condensate/make-up water system may be seeded with noise patterns and associated states from the library. As current data are received into the expert system, it may predict a state based on having learned noise patterns and associated states.
A library of noise patterns may be updated if a changed parameter resulted in a new noise pattern or if a predicted outcome or state did not occur in the absence of mitigation of a diagnosed problem. A library of noise patterns may be updated if a noise pattern resulted in an alternative state than what was predicted by the library. The update may occur after just one time that the state that actually occurred did not match the predicted state from the library. In other embodiments, it may occur after a threshold number of times. In embodiments, the library may be updated to apply one or more rules for comparison, such as rules that govern how many parameters to match along with the noise pattern, or the standard deviation for the match in order to accept the predicted outcome. For example, a baffle may be replaced in a static agitator in a pharmaceutical processing plant which may result in a changed noise pattern. In another example, as the seal on a pressure cooker in a food processing plant ages, the noise pattern associated with the pressure cooker may change.
In embodiments, the library of vibration fingerprints, noise sources and/or noise patterns may be available for subscription. The libraries may be used in offset systems to improve operation of the local system. Subscribers may subscribe at any level (e.g., component, machinery, installation, etc.) in order to access data that would normally not be available to them, such as because it is from a competitor, or is from an installation of the machinery in a different industry not typically considered. Subscribers may search on indicators/predictors based on or filtered by system conditions, or update an indicator/predictor with proprietary data to customize the library. The library may further include parameters and metadata auto-generated by deployed sensors throughout an installation, onboard diagnostic systems and instrumentation and sensors, ambient sensors in the environment, sensors (e.g., in flexible sets) that can be put into place temporarily, such as in one or more mobile data collectors, sensors that can be put into place for longer term use, such as being attached to points of interest on devices or systems, and the like.
In embodiments, a third party (e.g., RMOs, manufacturers) can aggregate data at the component level, equipment level, factory/installation level and provide a statistically valid data set against which to optimize their own systems. For example, when a new installation of a machine is contemplated, it may be beneficial to review a library for best data points to acquire in making state predictions. For example, a particular sensor package may be recommended to reliably determine if there will be a failure. For example, if vibration noise of equipment coupled with particular levels of local noise or other ambient sensed conditions reliably is an indicator of imminent failure, a given vibration transducer/temp/microphone package observing those elements may be recommended for the installation Knowing such information may inform the choice to rent or buy a piece of machinery or associated warranties and service plans, such as based on knowing the quantity and depth of information that may be needed to reliably maintain the machinery.
In embodiments, manufacturers may utilize the library to rapidly collect in-service information for machines to draft engineering specifications for new customers.
In embodiments, noise and vibration data may be used to remotely monitor installs and automatically dispatch a field crew.
In embodiments, noise and vibration data may be used to audit a system. For example, equipment running outside the range of a licensed duty cycle may be detected by a suite of vibration sensors and/or ambient/local noise sensors. In embodiments, alerts may be triggered of potential out-of-warranty violations based on data from vibration sensors and/or ambient/local noise sensors.
In embodiments, noise and vibration data may be used in maintenance. This may be particularly useful where multiple machines are deployed that may vibrationally interact with the environment, such as two large generating machines on the same floor or platform with each other, such as in power generation plants.

The term industrial system (and similar terms) as utilized herein should be understood broadly. Without limitation to any other aspect or description of the present disclosure, an industrial system includes any large scale process system, mechanical system, chemical system, assembly line, oil and gas system (including, without limitation, production, transportation, exploration, remote operations, offshore operations, and/or refining), mining system (including, without limitation, production, exploration, transportation, remote operations, and/or underground operations), rail system (yards, trains, shipments, etc.), construction, power generation, aerospace, agriculture, food processing, and/or energy generation. Certain components may not be considered industrial individually, but may be considered industrially in an aggregated system—for example a single fan, motor, and/or engine may be not an industrial system, but may be a part of a larger system and/or be accumulated with a number of other similar components to be considered an industrial system and/or a part of an industrial system. In certain embodiments, a system may be considered an industrial system for some purposes but not for other purposes—for example a large data server farm may be considered an industrial system for certain sensing operations, such as temperature detection, vibration, or the like, but not an industrial system for other sensing operations such as gas composition. Additionally, in certain embodiments, otherwise similar looking systems may be differentiated in determining whether such system are industrial systems, and/or which type of industrial system. For example, one data server farm may not, at a given time, have process stream flow rates that are critical to operation, while another data server farm may have process stream flow rates that are critical to operation (e.g., a coolant flow stream), and accordingly one data farm server may be an industrial system for a data collection and/or sensing improvement process or system, while the other is not. Accordingly, the benefits of the present disclosure may be applied in a wide variety of systems, and any such systems may be considered an industrial system herein, while in certain embodiments a given system may not be considered an industrial system herein. One of skill in the art, having the benefit of the disclosure herein and knowledge about a contemplated system ordinarily available to that person, can readily determine which aspects of the present disclosure will benefit a particular system, how to combine processes and systems from the present disclosure to enhance operations of the contemplated system. Certain considerations for the person of skill in the art, in determining whether a contemplated system is an industrial system and/or whether aspects of the present disclosure can benefit or enhance the contemplated system include, without limitation: the accessibility of portions of the system to positioning sensing devices; the sensitivity of the system to capital costs (e.g., initial installation) and operating costs (e.g., optimization of processes, reduction of power usage); the transmission environment of the system (e.g., availability of broadband internet; satellite coverage; wireless cellular access; the electro-magnetic (“EM”) environment of the system; the weather, temperature, and environmental conditions of the system; the availability of suitable locations to run wires, network lines, and the like; the presence and/or availability of suitable locations for network infrastructure, router positioning, and/or wireless repeaters); the availability of trained personnel to interact with computing devices; the desired spatial, time, and/or frequency resolution of sensed parameters in the system; the degree to which a system or process is well understood or modeled; the turndown ratio in system operations (e.g., high load differential to low load; high flow differential to low flow; high temperature operation differential to low temperature operation); the turndown ratio in operating costs (e.g., effects of personnel costs based on time (day, season, etc.); effects of power consumption cost variance with time, throughput, etc.); the sensitivity of the system to failure, down-time, or the like; the remoteness of the contemplated system (e.g., transport costs, time delays, etc.); and/or qualitative scope of change in the system over the operating cycle (e.g., the system runs several distinct processes requiring a variable sensing environment with time; time cycle and nature of changes such as periodic, event driven, lead times generally available, etc.). While specific examples of industrial systems and considerations are described herein for purposes of illustration, any system benefitting from the disclosures herein, and any considerations understood to one of skill in the art having the benefit of the disclosures herein, are specifically contemplated within the scope of the present disclosure.
The term sensor (and similar terms) as utilized herein should be understood broadly. Without limitation to any other aspect or description of the present disclosure, sensor includes any device configured to provide a sensed value representative of a physical value (e.g., temperature, force, pressure) in a system, or representative of a conceptual value in a system at least having an ancillary relationship to a physical value (e.g., work, state of charge, frequency, phase, etc.).
Example and non-limiting sensors include vibration, acceleration, noise, pressure, force, position, location, velocity, displacement, temperature, heat flux, speed, rotational speed (e.g., a tachometer), motion, accelerometers, magnetic field, electrical field, galvanic, current, flow (gas, fluid, heat, particulates, particles, etc.), level, proximity, gas composition, fluid composition, toxicity, corrosiveness, acidity, pH, humidity, hygrometer measures, moisture, density (bulk or specific), ultrasound, imaging, analog, and/or digital sensors. The list of sensed values is a non-limiting example, and the benefits of the present disclosure in many applications can be realized independent of the sensor type, while in other applications the benefits of the present disclosure may be dependent upon the sensor type.
The sensor type and mechanism for detection may be any type of sensor understood in the art. Without limitation, an accelerometer may be any type and scaling, for example 500 mV per g (1 g=9.8 m/s2), 100 mV, 1 V per g, 5 V per g, 10 V per g, 10 MV per g, as well as any frequency capability. It will be understood for accelerometers, and for all sensor types, that the scaling and range may be competing (e.g., in a fixed-bit or low bit A/D system), and/or selection of high resolution scaling with a large range may drive up sensor and/or computing costs, which may be acceptable in certain embodiments, and may be prohibitive in other embodiments. Example and non-limiting accelerometers include piezo-electric devices, high resolution and sampling speed position detection devices (e.g., laser based devices), and/or detection of other parameters (strain, force, noise, etc.) that can be correlated to acceleration and/or vibration. Example and non-limiting proximity probes include electro-magnetic devices (e.g., Hall effect, Variable Reluctance, etc.), a sleeve/oil film device, and/or determination of other parameters than can be correlated to proximity. An example vibration sensor includes a tri-axial probe, which may have high frequency response (e.g., scaling of 100 MV/g). Example and non-limiting temperature sensors include thermistors, thermocouples, and/or optical temperature determination.
A sensor may, additionally or alternatively, provide a processed value (e.g., a de-bounced, filtered, and/or compensated value) and/or a raw value, with processing downstream (e.g., in a data collector, controller, plant computer, and/or on a cloud-based data receiver). In certain embodiments, a sensor provides a voltage, current, data file (e.g., for images), or other raw data output, and/or a sensor provides a value representative of the intended sensed measurement (e.g., a temperature sensor may communicate a voltage or a temperature value). Additionally or alternatively, a sensor may communicate wirelessly, through a wired connection, through an optical connection, or by any other mechanism. The described examples of sensor types and/or communication parameters are non-limiting examples for purposes of illustration.
Additionally or alternatively, in certain embodiments, a sensor is a distributed physical device—for example where two separate sensing elements coordinate to provide a sensed value (e.g., a position sensing element and a mass sensing element may coordinate to provide an acceleration value). In certain embodiments, a single physical device may form two or more sensors, and/or parts of more than one sensor. For example, a position sensing element may form a position sensor and a velocity sensor, where the same physical hardware provides the sensed data for both determinations.
The term smart sensor, smart device (and similar terms) as utilized herein should be understood broadly. Without limitation to any other aspect or description of the present disclosure, a smart sensor includes any sensor and aspect thereof as described throughout the present disclosure. A smart sensor includes an increment of processing reflected in the sensed value communicated by the sensor, including at least basic sensor processing (e.g., de-bouncing, filtering, compensation, normalization, and/or output limiting), more complex compensations (e.g., correcting a temperature value based on known effects of current environmental conditions on the sensed temperature value, common mode or other noise removal, etc.), a sensing device that provides the sensed value as a network communication, and/or a sensing device that aggregates a number of sensed values for communication (e.g., multiple sensors on a device communicated out in a parseable or deconvolutable manner or as separate messages; multiple sensors providing a value to a single smart sensor, which relays sensed values on to a data collector, controller, plant computer, and/or cloud-based data receiver). The use of the term smart sensor is for purposes of illustration, and whether a sensor is a smart sensor can depend upon the context and the contemplated system, and can be a relative description compared to other sensors in the contemplated system. Thus, a given sensor having identical functionality may be a smart sensor for the purposes of one contemplated system, and just a sensor for the purposes of another contemplated system, and/or may be a smart sensor in a contemplated system during certain operating conditions, and just a sensor for the purposes of the same contemplated system during other operating conditions.
The terms sensor fusion, fused sensors, and similar terms, as utilized herein, should be understood broadly, except where context indicates otherwise, without limitation to any other aspect or description of the present disclosure. A sensor fusion includes a determination of second order data from sensor data, and further includes a determination of second order data from sensor data of multiple sensors, including involving multiplexing of streams of data, combinations of batches of data, and the like from the multiple sensors. Second order data includes a determination about a system or operating condition beyond that which is sensed directly. For example, temperature, pressure, mixing rate, and other data may be analyzed to determine which parameters are result-effective on a desired outcome (e.g., a reaction rate). The sensor fusion may include sensor data from multiple sources, and/or longitudinal data (e.g., taken over a period of time, over the course of a process, and/or over an extent of components in a plant—for example tracking a number of assembled parts, a virtual slug of fluid passing through a pipeline, or the like). The sensor fusion may be performed in real-time (e.g., populating a number of sensor fusion determinations with sensor data as a process progresses), off-line (e.g., performed on a controller, plant computer, and/or cloud-based computing device), and/or as a post-processing operation (e.g., utilizing historical data, data from multiple plants or processes, etc.). In certain embodiments, a sensor fusion includes a machine pattern recognition operation—for example where an outcome of a process is given to the machine and/or determined by the machine, and the machine pattern recognition operation determines result-effective parameters from the detected sensor value space to determine which operating conditions were likely to be the cause of the outcome and/or the off-nominal result of the outcome (e.g., process was less effective or more effective than nominal, failed, etc.). In certain embodiments, the outcome may be a quantitative outcome (e.g., 20% more product was produced than a nominal run) or a qualitative outcome (e.g., product quality was unacceptable, component X of the contemplated system failed during the process, component X of the contemplated system required a maintenance or service event, etc.).
In certain embodiments, a sensor fusion operation is iterative or recursive—for example an estimated set of result effective parameters is updated after the sensor fusion operation, and a subsequent sensor fusion operation is performed on the same data or another data set with an updated set of the result effective parameters. In certain embodiments, subsequent sensor fusion operations include adjustments to the sensing scheme—for example higher resolution detections (e.g., in time, space, and/or frequency domains), larger data sets (and consequent commitment of computing and/or networking resources), changes in sensor capability and/or settings (e.g., changing an A/D scaling, range, resolution, etc.; changing to a more capable sensor and/or more capable data collector, etc.) are performed for subsequent sensor fusion operations. In certain embodiments, the sensor fusion operation demonstrates improvements to the contemplated system (e.g., production quantity, quality, and/or purity, etc.) such that expenditure of additional resources to improve the sensing scheme are justified. In certain embodiments, the sensor fusion operation provides for improvement in the sensing scheme without incremental cost—for example by narrowing the number of result effective parameters and thereby freeing up system resources to provide greater resolution, sampling rates, etc., from hardware already present in the contemplated system. In certain embodiments, iterative and/or recursive sensor fusion is performed on the same data set, a subsequent data set, and/or a historical data set. For example, high resolution data may already be present in the system, and a first sensor fusion operation is performed with low resolution data (e.g., sampled from the high resolution data set), such as to allow for completion of sensor fusion processing operations within a desired time frame, within a desired processor, memory, and/or network utilization, and/or to allow for checking a large number of variables as potential result effective parameters. In a further example, a greater number of samples from the high resolution data set may be utilized in a subsequent sensor fusion operation in response to confidence that improvements are present, narrowing of the potential result effective variables, and/or a determination that higher resolution data is required to determine the result effective parameters and/or effective values for such parameters.
The described operations and aspects for sensor fusion are non-limiting examples, and one of skill in the art, having the benefit of the disclosures herein and information ordinarily available about a contemplated system, can readily design a system to utilize and/or benefit from a sensor fusion operation. Certain considerations for a system to utilize and/or benefit from a sensor fusion operation include, without limitation the number of components in the system; the cost of components in the system; the cost of maintenance and/or down-time for the system; the value of improvements in the system (production quantity, quality, yield, etc.); the presence, possibility, and/or consequences of undesirable system outcomes (e.g., side products, thermal and/or luminary events, environmental benefits or consequences, hazards present in the system); the expense of providing a multiplicity of sensors for the system; the complexity between system inputs and system outputs; the availability and cost of computing resources (e.g., processing, memory, and/or communication throughput); the size/scale of the contemplated system and/or the ability of such a system to generate statistically significant data; whether offset systems exist, including whether data from offset systems is available and whether combining data from offset systems will generate a statistically improved data set relative to the system considered alone; and/or the cost of upgrading, improving, or changing a sensing scheme for the contemplated system. The described considerations for a contemplated system that may benefit from or utilize a sensor fusion operation are non-limiting illustrations.
Certain systems, processes, operations, and/or components are described in the present disclosure as “offset systems” or the like. An offset system is a system distinct from a contemplated system, but having relevance to the contemplated system. For example, a contemplated refinery may have an “offset refinery,” which may be a refinery operated by a competitor, by a same entity operating the contemplated refinery, and/or a historically operated refinery that no longer exists. The offset refinery bears some relevant relationship to the contemplated refinery, such as utilizing similar reactions, process flows, production volumes, feed stock, effluent materials, or the like. A system which is an offset system for one purpose may not be an offset system for another purpose. For example, a manufacturing process utilizing conveyor belts and similar motors may be an offset process for a contemplated manufacturing process for the purpose of tracking product movement, understanding motor operations and failure modes, or the like, but may not be an offset process for product quality if the products being produced have distinct quality outcome parameters. Any industrial system contemplated herein may have an offset system for certain purposes. One of skill in the art, having the benefit of the present disclosure and information ordinarily available for a contemplated system, can readily determine what is disclosed by an offset system or offset aspect of a system.
Any one or more of the terms computer, computing device, processor, circuit, and/or server include a computer of any type, capable to access instructions stored in communication thereto such as upon a non-transient computer readable medium, whereupon the computer performs operations of systems or methods described herein upon executing the instructions. In certain embodiments, such instructions themselves comprise a computer, computing device, processor, circuit, and/or server. Additionally or alternatively, a computer, computing device, processor, circuit, and/or server may be a separate hardware device, one or more computing resources distributed across hardware devices, and/or may include such aspects as logical circuits, embedded circuits, sensors, actuators, input and/or output devices, network and/or communication resources, memory resources of any type, processing resources of any type, and/or hardware devices configured to be responsive to determined conditions to functionally execute one or more operations of systems and methods herein.
Certain operations described herein include interpreting, receiving, and/or determining one or more values, parameters, inputs, data, or other information. Operations including interpreting, receiving, and/or determining any value parameter, input, data, and/or other information include, without limitation: receiving data via a user input; receiving data over a network of any type; reading a data value from a memory location in communication with the receiving device; utilizing a default value as a received data value; estimating, calculating, or deriving a data value based on other information available to the receiving device; and/or updating any of these in response to a later received data value. In certain embodiments, a data value may be received by a first operation, and later updated by a second operation, as part of the receiving a data value. For example, when communications are down, intermittent, or interrupted, a first operation to interpret, receive, and/or determine a data value may be performed, and when communications are restored an updated operation to interpret, receive, and/or determine the data value may be performed.
Certain logical groupings of operations herein, for example methods or procedures of the current disclosure, are provided to illustrate aspects of the present disclosure. Operations described herein are schematically described and/or depicted, and operations may be combined, divided, re-ordered, added, or removed in a manner consistent with the disclosure herein. It is understood that the context of an operational description may require an ordering for one or more operations, and/or an order for one or more operations may be explicitly disclosed, but the order of operations should be understood broadly, where any equivalent grouping of operations to provide an equivalent outcome of operations is specifically contemplated herein. For example, if a value is used in one operational step, the determining of the value may be required before that operational step in certain contexts (e.g., where the time delay of data for an operation to achieve a certain effect is important), but may not be required before that operation step in other contexts (e.g., where usage of the value from a previous execution cycle of the operations would be sufficient for those purposes). Accordingly, in certain embodiments an order of operations and grouping of operations as described is explicitly contemplated herein, and in certain embodiments re-ordering, subdivision, and/or different grouping of operations is explicitly contemplated herein.

The example system 10902 further includes a sensor communication circuit 10920 (reference
In certain embodiments, sensor data values 10948 are provided to a data collector 10910, which may be in communication with multiple sensors 10908 and/or with a controller 10914. In certain embodiments, a plant computer 10912 is additionally or alternatively present. In the example system, the controller 10914 is structured to functionally execute operations of the sensor communication circuit 10920, pattern recognition circuit 10922, and/or the sensor learning circuit 10924, and is depicted as a separate device for clarity of description. Aspects of the controller 10914 may be present on the sensors 10908, the data controller 10910, the plant computer 10912, and/or on a cloud computing device 10916. In certain embodiments, all aspects of the controller 10914 may be present in another device depicted on the system 10902. The plant computer 10912 represents local computing resources, for example processing, memory, and/or network resources, that may be present and/or in communication with the industrial system 10904. In certain embodiments, the cloud computing device 10916 represents computing resources externally available to the industrial system 10904, for example over a private network, intra-net, through cellular communications, satellite communications, and/or over the internet. In certain embodiments, the data controller 10910 may be a computing device, a smart sensor, a MUX box, or other data collection device capable to receive data from multiple sensors and to pass-through the data and/or store data for later transmission. An example data controller 10910 has no storage and/or limited storage, and selectively passes sensor data therethrough, with a subset of the sensor data being communicated at a given time due to bandwidth considerations of the data controller 10910, a related network, and/or imposed by environmental constraints. In certain embodiments, one or more sensors and/or computing devices in the system 10902 are portable devices—for example a plant operator walking through the industrial system may have a smart phone, which the system 10902 may selectively utilize as a data controller 10910, sensor 10908—for example to enhance communication throughput, sensor resolution, and/or as a primary method for communicating sensor data values 10948 to the controller 10914.
The example system 10902 further includes a pattern recognition circuit 10922 that determines a recognized pattern value 10930 in response to a least a portion of the sensor data values 10948.
The example system 10902 further includes a sensor learning circuit 10924 that updates the sensed parameter group 10928 in response to the recognized pattern value 10930. The example sensor communication circuit 10920 further adjusts the interpreting the sensor data values 10948 in response to the updated sensed parameter group 10928.
An example system 10902 further includes the pattern recognition circuit 10922 and the sensor learning circuit 10924 iteratively performing the determining the recognized pattern value 10930 and the updating the sensed parameter group 10928 to improve a sensing performance value 10934. For example, the pattern recognition circuit 10922 may add sensors, remove sensors, and/or change sensor setting to modify the sensed parameter group 10928 based upon sensors which appear to be effective or ineffective predictors of the recognized pattern value 10930, and the sensor learning circuit 10924 may instruct a continued change (e.g., while improvement is still occurring), an increased or decreased rate of change (e.g., to converge more quickly on an improved sensed parameter group 10928), and/or instruct a randomized change to the sensed parameter group 10928 (e.g., to ensure that all potentially result effective sensors are being checked, and/or to avoid converging into a local optimal value).
Example and non-limiting options for the sensing performance value 10934 include: a signal-to-noise performance for detecting a value of interest in the industrial system (e.g., a determination that the prediction signal for the value is high relative to noise factors for one or more sensors of the sensed parameter group 10928, and/or for the sensed parameter group 10928 as a whole); a network utilization of the sensors in the industrial system (e.g., the sensor learning circuit 10924 may score a sensed parameter group 10928 relatively high where it is as effective or almost as effective as another sensed parameter group 10928, but results in lower network utilization); an effective sensing resolution for a value of interest in the industrial system (e.g., the sensor learning circuit 10924 may score a sensed parameter group 10928 relatively high where it provides a responsive prediction of the output value to smaller changes in input values); a power consumption value for a sensing system in the industrial system, the sensing system including the sensors (e.g., the sensor learning circuit 10924 may score a sensed parameter group 10928 relatively high where it is as effective or almost as effective as another sensed parameter group 10928, but results in lower power consumption); a calculation efficiency for determining the secondary value (e.g., the sensor learning circuit 10924 may score a sensed parameter group 10928 relatively high where it is as effective or almost as effective as another sensed parameter group 10928 in determining the secondary value 10932, but results in fewer processor cycles, lower network utilization, and/or lower memory utilization including stored memory requirements as well as intermediate memory utilization such as buffers); an accuracy and/or a precision of the secondary value (e.g., the sensor learning circuit 10924 may score a sensed parameter group 10928 relatively high where it provides a highly accurate and/or highly precise determination of the secondary value 10932); a redundancy capacity for determining the secondary value (e.g., the sensor learning circuit 10924 may score a sensed parameter group 10928 relatively high where it provides similar capability and/or resource utilization, but provides for additional sensing redundancy, such as being more robust to gaps in data from one or more of the sensors in the sensed parameter group 10928); and/or a lead time value for determining the secondary value 10932 (e.g., the sensor learning circuit 10924 may score a sensed parameter group 10928 relatively high where it provides an improved or sufficient lead time in the secondary value 10932 determination—for example to assist in avoiding over-temperature operation, spoiling an entire production run, determining whether a component has sufficient service life to complete a production run, etc.) Example and non-limiting calculation efficiency values include one or more determinations such as: processor operations to determine the secondary value 10932; memory utilization for determining the secondary value 10932; a number of sensor inputs from the number of sensors for determining the secondary value 10932; and/or supporting memory, such as long-term storage or buffers for supporting the secondary value 10932.
Example systems include one or more, or all, of the sensors 10908 as analog sensors and/or as remote sensors. An example system includes the secondary value 10932 being a value such as: a virtual sensor output value;
a process prediction value (e.g., a success value for a production run, an overtemperature value, an overpressure value, a product quality value, etc.); a process state value (e.g., a stage of the process, a temperature at a time and location in the process); a component prediction value (e.g., a component failure prediction, a component maintenance or service prediction, a component response to an operating change prediction); a component state value (a remaining service life or maintenance interval for a component); and/or a model output value having the sensor data values 10948 from the fused number of sensors 10926 as an input. An example system includes the fused number of sensors 10926 being one or more of the combinations of sensors such as: a vibration sensor and a temperature sensor; a vibration sensor and a pressure sensor; a vibration sensor and an electric field sensor; a vibration sensor and a heat flux sensor; a vibration sensor and a galvanic sensor; and/or a vibration sensor and a magnetic sensor.
An example sensor learning circuit 10924 further updates the sensed parameter group 10928 by performing an operation such as: updating a sensor selection of the sensed parameter group 10928 (e.g., which sensors are sampled); updating a sensor sampling rate of at least one sensor from the sensed parameter group (e.g., how fast the sensors provide information, and/or how fast information is passed through the network); updating a sensor resolution of at least one sensor from the sensed parameter group (e.g., changing or requesting a change in a sensor resolution, utilizing additional sensors to provide greater effective resolution); updating a storage value corresponding to at least one sensor from the sensed parameter group (e.g., storing data from the sensor at a higher or lower resolution, and/or over a longer or shorter time period); updating a priority corresponding to at least one sensor from the sensed parameter group (e.g., moving a sensor up to a higher priority—for example, if environmental conditions prevent data receipt from all planned sensors, and/or reducing a time lag between creation of the sensed data and receipt at the sensor learning circuit 10924); and/or updating at least one of a sampling rate, sampling order, sampling phase, and/or a network path configuration corresponding to at least one sensor from the sensed parameter group.
An example pattern recognition circuit 10922 further determines the recognized pattern value 10930 by performing an operation such as: determining a signal effectiveness of at least one sensor of the sensed parameter group and the updated sensed parameter group relative to a value of interest 10950 (e.g., determining that a sensor value is a good predictor of the value of interest 10950); determining a sensitivity of at least one sensor of the sensed parameter group 10928 and the updated sensed parameter group 10928 relative to the value of interest 10950 (e.g., determining the relative sensitivity of the determined value of interest to small changes in operating conditions based on the selected sensed parameter group 10928); determining a predictive confidence of at least one sensor of the sensed parameter group 10928 and the updated sensed parameter group 10928 relative to the value of interest 10950; determining a predictive delay time of at least one sensor of the sensed parameter group 10928 and the updated sensed parameter group 10928 relative to the value of interest 10950; determining a predictive accuracy of at least one sensor of the sensed parameter group 10928 and the updated sensed parameter group 10928 relative to the value of interest 10950; determining a classification precision of at least one sensor of the sensed parameter group 10928 (e.g., determining the accuracy of classification of a pattern by a machine classifier based on use of the at least one sensor); determining a predictive precision of at least one sensor of the sensed parameter group 10928 and the updated sensed parameter group 10928 relative to the value of interest 10950; and/or updating the recognized pattern value 10930 in response to external feedback, which may be received as external data 10952 (e.g., where an outcome is known, such as a maintenance event, product quality determination, production outcome determination, etc., the detection of the recognized pattern value 10930 is thereby improved according to the conditions of the system before the known outcome occurred). Example and non-limiting values of interest 10950 include: a virtual sensor output value; a process prediction value; a process state value; a component prediction value; a component state value; and/or a model output value having the sensor data values from the fused plurality of sensors as an input.
An example pattern recognition circuit 10922 further accesses cloud-based data 10954 including a second number of sensor data values, the second number of sensor data values corresponding to at least one offset industrial system. An example sensor learning circuit 10924 further accesses the cloud-based data 10954 including a second updated sensor parameter group corresponding to the at least one offset industrial system. Accordingly, the pattern recognition circuit 10922 can improve pattern recognition in the system based on increased statistical data available from an offset system. Additionally, or alternatively, the sensor learning circuit 10924 can improve more rapidly and with greater confidence based upon the data from the offset system—including determining which sensors in the offset system found to be effective in predicting system outcomes.
An example system includes an industrial system including an oil refinery. An example oil refinery includes one or more compressors for transferring fluids throughout the plant, and/or for pressurizing fluid streams (e.g., for reflux in a distillation column). Additionally, or alternatively, the example oil refinery includes vacuum distillation, for example, to fractionate hydrocarbons. The example oil refinery additionally includes various pipelines in the system for transferring fluids, bringing in feedstock, final product delivery, and the like. An example system includes a number of sensors configured to determine each aspect of a distillation column—for example temperatures of various fluid streams, temperatures, and compositions of individual contact trays in the column, measurements of the feed and reflux, as well as of the effluent or separated products. The design of a distillation column is complex, and optimal design can depend upon the sizing of boilers, compressors, the contact conditions within the column, as well as the composition of feedstock, all of which can vary significantly. Additionally, the optimal position for effective sensing of conditions in a pipeline can vary with fluid flow rates, environmental conditions (e.g., causing variation in heat transfer rates), the feedstock utilized, and other factors. Additionally, wear or loss of capability in a boiler, compressor, or other operating equipment can change the system response and capabilities, rendering a single point optimization—including where sensors should be positioned and how they should sample data—to be non-optimal as the system ages.
Provision of multiple sensors throughout the system can be costly, not necessarily because the sensors are expensive, but because the sensors provide data which may be prohibitive to transmit, store, and utilize. Cost may involve costs of transmitting over networks, as well as costs of operations, such as numbers of input/output operations (and time required to undertake such operations). The example system includes providing a large number of sensors throughout the system, and determining which of the sensors are effective for control and optimization of the distillation process. Additionally, as the feedstock and/or environmental conditions change, the optimal sensor package for both optimization and control may change. The example system utilizes a pattern recognition circuit to determine which sensors, including sensor fusion operations (including selection of groups, selection of multiplexing and combination, and the like), are effective in controlling the desired parameters of the distillation, and in determining the optimal values for temperatures, flow rates, entry trays for feed and reflux, and/or reflux rates. Additionally, the sensor learning circuit is capable, over time and/or utilizing offset oil refineries, to rapidly converge on various sensor packages that are appropriate for a multiplicity of operating conditions. If an unexpected operating condition occurs—for example an off-nominal operation of a compressor, the sensor learning circuit is capable of migrating the system to the correct sensing and operating conditions for the unexpected operating condition. The ability to flexibly utilize a multiplicity of sensors allows for the system to be flexible in response to changing conditions without providing for excessive capability in transmission and storage of sensor data. Accordingly, operations of the distillation column are improved and can be optimized for a large number of operating conditions. Additionally, alerts for the distillation column, based upon recognition of patterns indicating off-nominal operation, can be readily prepared to adjust or shut down the process before significant product quality loss and/or hazardous conditions develop. Example sensor fusion operations for a refinery include vibration information combined with temperatures, pressures, and/or composition (e.g., to determine compressor performance); temperature and pressure, temperature and composition, and/or composition and pressure (e.g., to determine feedstock variance, contact tray performance, and/or a component failure).
An example refinery system includes storage tanks and/or boiler feed water. Example system determinations include a sensor fusion to determine a storage tank failure and/or off-nominal operation, such as through a temperature and pressure fusion, and/or a vibration determination with a non-vibration determination (e.g., detecting leaks, air in the system, and/or a feed pump issue). Certain further example system determinations include a sensor fusion to determine a boiler feed water failure, such as through a sensor fusion including flow rate, pressure, temperature, and/or vibration. Any one or more of these parameters can be utilized to determine a system leak, failure, wear of a feed pump, scaling, and/or to reduce pumping losses while maintaining system flow rates. Similarly, an example industrial system includes a power generation system having a condensate and/or make-up water system, where a sensor fusion provides for a sensed parameter group and prediction of failures, maintenance, and the like.
An example industrial system includes an irrigation system for a field or a system of fields. Irrigations systems are subject to significant variability in the system (e.g., inlet pressures and/or water levels, component wear and maintenance) as well as environmental variability (e.g., types and distribution of crops planted, weather, soil moisture, humidity, seasonal variability in the sun, cloud coverage, and/or wind variance). Additionally, irrigation systems tend to be remotely located where high bandwidth network access, maintenance facilities, and/or even personnel for oversight are not readily available. An example system includes a multiplicity of sensors capable of detecting conditions for the irrigation system, without requiring that all of the sensors transmit or store data on a continuous basis. The pattern recognition circuit can readily determine the most important set of sensors to effectively predict patterns and those system conditions requiring a response (e.g., irrigation cycles, positioning, and the like). The sensor learning circuit provides for responsive migration of the sensed parameter group to variability, which may occur on slower (e.g., seasonal, climate change, etc.) or faster cycles (e.g., equipment failure, weather conditions, step change events such as planting or harvesting). Additionally, alerts for remote facilities can be readily prepared with confidence that the correct sensor package is in place for determining an off-nominal condition (e.g., imminent failure or maintenance requirement for a pump).
An example industrial system includes a chemical or pharmaceutical plant. Chemical plants require specific operating conditions, flow rates, temperatures, and the like to maintain proper temperatures, concentrations, mixing, and the like throughout the system. In many systems, there are numerous process steps, and an off-nominal or uncoordinated operation in one part of the process can result in reduced yields, a failed process, and/or a significant reduction in production capacity as coordinated processes must respond (or as coordinated processes fail to respond). Accordingly, a very large number of systems are required to minimally define the system, and in certain embodiments a prohibitive number of sensors are required, from a data transmission and storage viewpoint, to keep sensing capability for a broad range of operating conditions. Additionally, the complexity of the system results in difficulty optimizing and coordinating system operations even where sufficient sensors are present. In certain embodiments, the pattern recognition circuit can determine the sensing parameter groups that provide high resolution understanding of the system, without requiring that all of the sensors store and transmit data continuously. Further, the utilization of a sensor fusion provides for the opportunity to abstract desired outputs, for example “maximize yield” or “minimize an undesirable side reaction” without requiring a full understanding from the operator of which sensors and system conditions are most effective to achieve the abstracted desired output. Example components in a chemical or pharmaceutical plan amenable to control and predictions based on a sensor fusion operation include an agitator, a pressure reactor, a catalytic reactor, and/or a thermic heating system. Example sensor fusion operations to determine sensed parameter groups and tune the pattern recognition circuit include, without limitation, a vibration sensor combined with another sensor type, a composition sensor combined with another sensor type, a flow rate determination combined with another sensor type, and/or a temperature sensor combined with another sensor type. The sensor fusion best suited for a particular application can be converged upon by the sensor learning circuit, but also depends upon the type of component that is subject to predictions, as well as the type of desired outputs pursued by the operator. For example, agitators are amenable to vibration sensing, as well as uniformity of composition detection (e.g., high resolution temperature), expected reaction rates in a properly mixed system, and the like. Catalytic reactors are amenable to temperature sensing (based on the reaction thermodynamics), composition detection (e.g., for expected reactants, as well as direct detection of catalytic material), flow rates (e.g., gross mechanical failure, reduced volume of beads, etc.), and/or pressure detection (e.g., indicative of or coupled with flow rate changes).
An example industrial system includes a food processing system. Example food processing systems include pressurization vessels, stirrers, mixers, and/or thermic heating systems. Control of the process is critical to maintain food safety, product quality, and product consistency. However, most input parameters to the food processing system are subject to high variability—for example basic food products are inherently variable as natural products, with differing water content, protein content, and aesthetic variation. Additionally, labor cost management, power cost management, and variability in supply water, etc., provide for a complex process where determination of the process control variables, sensed parameters to determine these, and optimization of sensing in response to process variation are a difficult problem to resolve. Food processing systems are often cost conscious, and capital costs (e.g., for a robust network and computing system for optimization) are not readily incurred. Further, a food processing system may manufacture a wide variety of products on similar or the same production facilities—for example, to support an entire product line and/or due to seasonal variations. Accordingly, a sensor setup for one process may not support another process well. An example system includes the pattern recognition circuit determining the sensing parameter groups that provide a strong signal response in target outcomes even in light of high variability in system conditions. The pattern recognition circuit can provide for numerous sensed group parameter options available for different process conditions without requiring extensive computing or data storage resources. Additionally, the sensor learning circuit provides for rapid response of the sensing system to changes in the process conditions, including updating the sensed group parameter options to pursue abstracted target outputs without the operator having to understand which sensed parameters best support the output goals. The sensor fusion best suited for a particular application can be converged upon by the sensor learning circuit, but also depends upon the type of component that is subject to predictions, as well as the type of desired outputs pursued by the operator. For example, control of and predictions for pressurization vessels, stirrers, mixers, and/or thermic heating systems are amenable to a sensor fusion with a temperature determination combined with a non-temperature determination, a vibration determination combined with a non-vibration determination, and/or a heat map combined with a rate of change in the heat map and/or a non-heat map determination. An example system includes a sensor fusion with a vibration determination and a non-vibration determination, wherein predictive information for a mixer and/or a stirrer is provided. An example system includes a sensor fusion with a pressure determination, a temperature determination, and/or a non-pressure determination, wherein predictive information for a pressurization vessel is provided.

The example system 11000 further includes a pattern recognition circuit 11020 that determines a recognized pattern value 11028 in response to a least a portion of the sensor data values 11034, and a system characterization circuit 11022 that provides a system characterization value 11030 for the industrial system in response to the recognized pattern value 11028. The system characterization value 11030 includes any value determined from the pattern recognition operations of the pattern recognition circuit 11020, including determining that a system condition of interest is present, a component condition of interest is present, an abstracted condition of the system or a component is present (e.g., a product quality value; an operation cost value; a component health, wear, or maintenance value; a component capacity value; and/or a sensor saturation value) and/or is predicted to occur within a time frame (e.g., calendar time, operational time, and/or a process stage) of interest. Pattern recognition operations include determining that operations compatible with a previously known pattern, operations similar to a previously known pattern and/or extrapolated from previously known pattern information (e.g., a previously known pattern includes a temperature response for a first component, and a known or estimated relationship between components allows for a determination that a temperature for a second component will exceed a threshold based upon the pattern recognition for the first component combined with the known or estimated relationship).
Non-limiting descriptions of a number of examples of a system characterization value 11030 are described following. An example system characterization value 11030 includes a predicted outcome for a process associated with the industrial system—for example a product quality description, a product quantity description, a product variability description (e.g., the expected variability of a product parameter predicted according to the operating conditions of the system), a product yield description, a net present value (NPV) for a process, a process completion time, a process chance of completion success, and/or a product purity result. The predicted outcome may be a batch prediction (e.g., a single run, or an integer number of runs, of the process, and the associated predicted outcome), a time based prediction (e.g., the projected outcome of the process over the next day, the next three weeks, until a scheduled shutdown, etc.), a production defined prediction (e.g., the projected outcome over the next 1,000 units, over the next 47 orders, etc.), and/or a rate of change based outcome (e.g., projected for 3 component failures per month, an emissions output per year, etc.). An example system characterization value 11030 includes a predicted future state for a process associated with the industrial system—for example an operating temperature at a given future time, an energy consumption value, a volume in a tank, an emitted noise value at a school adjacent to the industrial system, and/or a rotational speed of a pump. The predicted future state may be time based (e.g., at 4 PM on Thursday), based on a state of the process (e.g., during the third stage, during system shutdown, etc.), and/or based on a future state of particular interest (e.g., peak energy consumption, highest temperature value, maximum noise value, time or process stage when a maximum number of personnel will be within 50 feet of a sensitive area, time or process stage when an aspect of the system redundancy is at a lowest point—e.g., for determining high risk points in a process, etc.). An example system characterization value 11030 includes a predicted off-nominal operation for the process associated with the industrial system—for example when a component capacity of the system will exceed nominal parameters (although, possibly, not experience a failure), when any parameter in the system will be three standard deviations away from normal operations, when a capacity of a component will be under-utilized, etc. An example system characterization value 11030 includes a prediction value for one of the number of components—for example an operating condition at a point in time and/or process stage. An example system characterization value 11030 includes a future state value for one of the number of components. The predicted future state of a component may be time based, based on a state of the process, and/or based on a future state of particular interest (e.g., a highest or lowest value predicted for the component). An example system characterization value 11030 includes an anticipated maintenance health state information for one of the number of components, including at a particular time, a process stage, a lowest value predicted until a next maintenance event, etc. An example system characterization value 11030 includes a predicted maintenance interval for at least one of the number of components (e.g., based on current usage, anticipated usage, planned process operations, etc.). An example system characterization value 11030 includes a predicted off-nominal operation for one of the number of components—for example at a selected time, a process stage, and/or a future state of particular interest. An example system characterization value 11030 includes a predicted fault operation for one of the plurality of components—for example at a selected time, a process stage, any fault occurrence predicted based on current usage, anticipated usage, planned process operations, and/or a future state of particular interest. An example system characterization value 11030 includes a predicted exceedance value for one of the number of components, where the exceedance value includes exceedance of a design specification, and/or exceedance of a selected threshold. An example system characterization value 11030 includes a predicted saturation value for one of the plurality of sensors for example at a selected time, a process stage, any saturation occurrence predicted based on current usage, anticipated usage, planned process operations, and/or a future state of particular interest.
Any values for the prediction value 11030 may be raw values (e.g., a temperature value), derivative values (e.g., a rate of change of a temperature value), accumulated values (e.g., a time spent above one or more temperature thresholds) including weighted accumulated values, and/or integrated values (e.g., an area over a temperature-time curve at a temperature value or temperature trajectory of interest). The provided examples list temperature, but any prediction value 11030 may be utilized, including at least vibration, system throughput, pressure, etc. In certain embodiments, combinations of one or more prediction values 11030 may be utilized.
It will be appreciated in light of the disclosure that combining prediction values 11030 can create particularly powerful combinations for system analysis, control, and risk management, which are specifically contemplated herein. For example, a first prediction value may indicate a time or process stage for a maximum flow rate through the system, and a second prediction value may determine the predicted state of one or more components of the system that is present at that particular time or process stage. In another example, a first prediction value indicates a lowest margin of the system in terms of capacity to deliver (e.g., by determining a point in the process wherein at least one component has a lowest operating margin, and/or where a group of components have a statistically lower operating margin due to the risk induced by a number of simultaneous low operating margins), and a second prediction value testing a system risk (e.g., loss of inlet water, loss of power, increase in temperature, change in environmental conditions that reduce or increase heat transfer, or that preclude the emission of certain effluents), and the combined risk of separate events can be assessed on the total system risk. Additionally, the prediction values may be operated with a sensitivity check (e.g., varying system conditions within margins to determine if some failure may occur), wherein the use of the prediction value allows for the sensitivity check to be performed with higher resolution at high risk points in the process.
An example system 11000 further includes a system collaboration circuit 11024 that interprets external data 11036, and where the pattern recognition circuit 11020 further determines the recognized pattern value 11028 further in response to the external data 11036. External data 11036 includes, without limitation, data provided from outside the system 11000 and/or outside the controller 11012. Non-limiting example external data 11036 include entries from an operator (e.g., indicating a failure, a fault, and/or a service event). An example pattern recognition circuit 11020 further iteratively improves pattern recognition operations in response to the external data 11036 (e.g., where an outcome is known, such as a maintenance event, product quality determination, production outcome determination, etc., the detection of the recognized pattern value 11028 is thereby improved according to the conditions of the system before the known outcome occurred). Example and non-limiting external data 11036 includes data such as: an indicated process success value; an indicated process failure value; an indicated component maintenance event; an indicated component failure event; an indicated process outcome value; an indicated component wear value; an indicated process operational exceedance value; an indicated component operational exceedance value; an indicated fault value; and/or an indicated sensor saturation value.
An example system 11000 further includes a system collaboration circuit 11024 that interprets cloud-based data 11032 including a second number of sensor data values, the second number of sensor data values corresponding to at least one offset industrial system, and where the pattern recognition circuit 11020 further determines the recognized pattern value 11028 further in response to the cloud-based data 11032. An example pattern recognition circuit 11020 further iteratively improves pattern recognition operations in response to the cloud-based data 11032. An example sensed parameter group 11026 includes a triaxial vibration sensor, a vibration sensor and a second sensor that is not a vibration sensor, the second sensor being a digital sensor, and/or a number of analog sensors.
An example system includes an industrial system including an oil refinery. An example oil refinery includes one or more compressors for transferring fluids throughout the plant, and/or for pressurizing fluid streams (e.g., for reflux in a distillation column). Additionally, or alternatively, the example oil refinery includes vacuum distillation, for example to fractionate hydrocarbons. The example oil refinery additionally includes various pipelines in the system for transferring fluids, bringing in feedstock, final product delivery, and the like. An example system includes a number of sensors configured to determine each aspect of a distillation column—for example temperatures of various fluid streams, temperatures, and compositions of individual contact trays in the column, measurements of the feed and reflux, as well as of the effluent or separated products. The design of a distillation column is complex, and optimal design can depend upon the sizing of boilers, compressors, the contact conditions within the column, as well as the composition of feedstock, which can vary significantly. Additionally, the optimal position for effective sensing of conditions in a pipeline can vary with fluid flow rates, environmental conditions (e.g., causing variation in heat transfer rates), the feedstock utilized, and other factors. Additionally, wear or loss of capability in a boiler, compressor, or other operating equipment can change the system response and capabilities, rendering a single point optimization, including where sensors should be positioned and how they should sample data, to be non-optimal as the system ages.
Provision of multiple sensors throughout the system can be costly, not necessarily because the sensors are expensive, but because the sensors provide data that may be prohibitive to transmit, store, and utilize. The example system includes providing a large number of sensors throughout the system, and predicting the future states of components, process variables, products, and/or emissions for the system. The example system utilizes a pattern recognition circuit to determine not only the future predicted state of parameters, but when the future predicted state of parameters will be of interest, and/or will combine with other future predicted state of parameters to create additional risks or opportunities.
Additionally, the system characterization circuit and the system collaboration circuit can improve predictions and/or system characterizations over time, and/or utilizing offset oil refineries, to more robustly make predictions or system characterizations, which can provide for earlier detection, longer term planning for overall enterprise optimization, and/or to allow the industrial system to operate closer to margins. If an unexpected operating condition occurs—for example an off-nominal operation of a compressor, the sensor collaboration circuit is able to migrate the system prediction and improve the capability to detect the conditions that caused the unexpected operating condition in the system, and/or in offset systems. Additionally, alerts for the distillation column, based upon predictions indicating off-nominal operation, marginal operation, high risk operation, and/or upcoming maintenance or potential failures, can be readily prepared to provide visibility to risks that otherwise may not be apparent by simply looking at system capacities and past experience without rigorous analysis.
Example sensor fusion operations for a refinery include vibration information combined with temperatures, pressures, and/or composition (e.g., to determine compressor performance); temperature and pressure, temperature and composition, and/or composition, and pressure (e.g., to determine feedstock variance, contact tray performance, and/or a component failure).
An example refinery system includes storage tanks and/or boiler feed water. Example system determinations include a sensor fusion to determine a storage tank failure and/or off-nominal operation, such as through a temperature and pressure fusion, and/or a vibration determination with a non-vibration determination (e.g., detecting leaks, air in the system, and/or a feed pump issue). Certain further example system predictions include a sensor fusion to determine a boiler feed water failure, such as through a sensor fusion including flow rate, pressure, temperature, and/or vibration. Any one or more of these parameters can be utilized to predict a system leak, failure, wear of a feed pump, and/or scaling.
Similarly, an example industrial system includes a power generation system having a condensate and/or make-up water system, where a sensor fusion provides for a sensed parameter group and prediction of failures, maintenance, and the like. The system characterization circuit, utilizing sensor fusion and/or a continuous machine learning process, can predict failures, off-nominal operations, component health, and/or maintenance events for, without limitation, compressors, piping, storage tanks, and/or boiler feed water for an oil refinery.
An example industrial system includes an irrigation system for a field or a system of fields. Irrigations systems are subject to significant variability in the system (e.g., inlet pressures and/or water levels, component wear and maintenance) as well as environmental variability (e.g., types and distribution of crops planted, weather, soil moisture, humidity, seasonal variability in the sun, cloud coverage, and/or wind variance). Additionally, irrigation systems tend to be remotely located where high bandwidth network access, maintenance facilities, and/or even personnel for oversight are not readily available. An example system includes a multiplicity of sensors capable to enable prediction of conditions for the irrigation system, without requiring that all of the sensors transmit or store data on a continuous basis. The pattern recognition circuit can readily determine the most important set of sensors to effectively predict patterns and thus system conditions requiring a response (e.g., irrigation cycles, positioning, and the like). Additionally, alerts for remote facilities can be readily prepared, with confidence that the correct sensor package is in place for predicting an off-nominal condition (e.g., imminent failure or maintenance requirement for a pump). In certain embodiments, the system may determine an off-nominal process condition such as water feed availability being below normal (e.g., based upon recognized pattern conditions such as recent precipitation history, water production history from the irrigation system or other systems competing for the same water feed), structured news alerts or external data, etc., and update the sensed parameter group, for example to confirm the water feed availability (e.g., a water level sensor in a relevant location), to confirm that acceptable conditions are available that water delivery levels can be dropped (e.g., a humidity sensor, and/or a prompt to a user), and/or to confirm that sufficient available secondary sources are available (e.g., an auxiliary water level sensor).
An example industrial system includes a chemical or pharmaceutical plant. Chemical plants require specific operating conditions, flow rates, temperatures, and the like to maintain proper temperatures, concentrations, mixing, and the like throughout the system. In many systems, there are numerous process steps, and an off-nominal or uncoordinated operation in one part of the process can result in reduced yields, a failed process, and/or a significant reduction in production capacity as coordinated processes must respond (or as coordinated processes fail to respond). Accordingly, a very large number of systems are required to minimally define the system, and in certain embodiments a prohibitive number of sensors are required, from a data transmission and storage viewpoint, to keep sensing capability for a broad range of operating conditions. Additionally, the complexity of the system results in difficulty optimizing and coordinating system operations even where sufficient sensors are present. In certain embodiments, the pattern recognition circuit can predict the sensing parameter groups that provide high resolution understanding of the system, without requiring that all of the sensors store and transmit data continuously. Further, the pattern recognition circuit can highlight the predicted system risks and capacity limitations for upcoming process operations, where the risks are buried in the complex process. Accordingly, this means it can confidently be operated closer to margins, at a lower cost, and/or maintenance or system upgrades can be performed before failures or capacity limitations are experienced.
Further, the utilization of a sensor fusion provides for the opportunity to abstract desired predictions, such as “maximize quality” or “minimize and undesirable side reaction” without requiring a full understanding from the operator of which sensors and system conditions are most effective to achieve the abstracted desired output. Further, the predictive nature of the pattern recognition circuit allows for changes in the process to support the desired outcome to be implemented before the process is committed to a sub-optimal outcome. Example components in a chemical or pharmaceutical plan amenable to control and predictions based on operations of the pattern recognition circuit and/or a sensor fusion operation include an agitator, a pressure reactor, a catalytic reactor, and/or a thermic heating system. Example sensor fusion operations to determine sensed parameter groups and tune the pattern recognition circuit include, without limitation, a vibration sensor combined with another sensor type, a composition sensor combined with another sensor type, a flow rate determination combined with another sensor type, and/or a temperature sensor combined with another sensor type. For example, agitators are amenable to vibration sensing, as well as uniformity of composition detection (e.g., high resolution temperature), expected reaction rates in a properly mixed system, and the like. Catalytic reactors are amenable to temperature sensing (based on the reaction thermodynamics), composition detection (e.g., for expected reactants, as well as direct detection of catalytic material), flow rates (e.g., gross mechanical failure, reduced volume of beads, etc.), and/or pressure detection (e.g., indicative of or coupled with flow rate changes).
An example industrial system includes a food processing system. Example food processing systems include pressurization vessels, stirrers, mixers, and/or thermic heating systems. Control of the process is critical to maintain food safety, product quality, and product consistency. However, most input parameters to the food processing system are subject to high variability—for example basic food products are inherently variable as natural products, with differing water content, protein content, and other aesthetic variation. Additionally, labor cost management, power cost management, and variability in supply water, etc., provide for a complex process where determination of the predictive variables, sensed parameters to determine these, and optimization of predicting in response to process variation are a difficult problem to resolve. Food processing systems are often cost conscious, and capital costs (e.g., for a robust network and computing system for optimization) are not readily incurred. Further, a food processing system may manufacture wide variance of products on similar or the same production facilities, for example to support an entire product line and/or due to seasonal variations, and accordingly a predictive operation for one process may not support another process well. Example systems include the pattern recognition circuit determining the sensing parameter groups that provide a strong signal response in target outcomes even in light of high variability in system conditions. The pattern recognition circuit can provide for numerous sensed group parameter options available for different process conditions without requiring extensive computing or data storage resources, and accordingly achieve relevant predictions for a wide variety of operating conditions. For example, control of and predictions for pressurization vessels, stirrers, mixers, and/or thermic heating systems are amenable to operations of the pattern recognition circuit, and/or a sensor fusion with a temperature determination combined with a non-temperature determination, a vibration determination combined with a non-vibration determination, and/or a heat map combined with a rate of change in the heat map and/or a non-heat map determination. An example system includes a pattern recognition circuit operation and/or a sensor fusion with a vibration determination and a non-vibration determination, wherein predictive information for a mixer and/or a stirrer is provided; and/or with a pressure determination, a temperature determination, and/or a non-pressure determination, wherein predictive information for a pressurization vessel is provided.

In embodiments, the identified plurality of sensors includes at least one sensor through which the condition(s) will be monitored.
In embodiments, a system for data collection in an industrial environment may route data from a plurality of sensors in the industrial environment to wearable haptic stimulators that present the data from the sensors as human detectable stimuli including at least one of tactile, vibration, heat, sound, and force. In embodiments, the haptic stimulus represents an effect on the machine resulting from the sensed data. In embodiments, a bending effect may be presented as bending a finger of a haptic glove. In embodiments, a vibrating effect may be presented as vibrating a haptic arm band. In embodiments, a heating effect may be presented as an increase in temperature of a haptic wrist band. In embodiments, an electrical effect (e.g., over voltage, current, and others) may be presented as a change in sound of a phatic audio system.
In embodiments, an industrial machine operator haptic user interface may be adapted to provide haptic stimuli to the operator that is responsive to the operator's control of the machine, wherein the stimuli indicate an impact on the machine as a result of the operator's control and interaction with objects in the environment as a result thereof. In embodiments, sensed conditions of the machine that exceed an acceptable range may be presented to the operator through the haptic user interface. In embodiments, the sensed conditions of the machine that are within an acceptable range may not be presented to the operator through the haptic user interface. In embodiments, the sensed conditions of the machine that are within an acceptable range may presented as natural language representations of confirmation of the operator control.

When a vehicle that the operator is controlling approaches an obstacle along a lateral side of the vehicle, an inflatable bellows may be inflated, exerting pressure against the leg of the operator closest to the side of the vehicle approaching the obstacle.

A deformation sensor can take the form of a passive (visual, infrared) or active scanning (Lidar, sonar) system that captures data from a target and compares it to historical data on the shape or orientation of the component to detect variations. Camera sensors are configured with a lens to capture continuous and still visible and invisible photon information cast upon or reflected by a target. Ultraviolet sensors can similarly capture continuous and still frame information about a target and its surrounds. Infrared sensors can capture light and heat emission data from a target. Audio sensors such as directional and omnichannel microphones can measure the frequency and amplitude of sonic wave data emitting from a target or its environment, and this data can be compared over time to detect anomalies when the amplitude or quality of the sound generated by the target exceeds or varies from predetermined or historical levels. Vibration sensors can be used in a similar manner, capturing extremely low frequency sound as well as physical perturbations and rhythms of a target over time. Viscosity sensors can be installed in-line in the lubrication system of a system or vehicle or can be movable and make ad-hoc measurements and evaluations of the continuous or instantaneous viscosity of the lubricating material for a target. Chemical sensors can vary widely in what analyte (target chemical) they detect, and in the case of vehicles or stationary machinery, can be configured with variable receptors capable of capturing and recognizing numerous conditions of a target. Specific target sensors such as rust sensors or overheat sensors can sense when a target such as an apparatus, metal structure or chemical lubricant has started to change chemically over time. These chemical sensors can be multi- or single-purpose, and can be integrated within a structure, such as the frame or chassis of a vehicle or the stationary or movable portions of an assembly line, or the mechanical motive power of an engine or robotic machinery. Or they can be attached to a portable self-propelled data acquisition system that is deployed to measure the target. When activated these chemical sensors make contact or take samples from the target and perform chemical analysis and report the state of the results to a data circuit. A solid chemical sensor can take solid chemical samples (rather than gaseous or liquid samples) and determine the presence of a particular chemical or the composition by detecting multiple chemicals in a sample. A pH sensor can be used to detect the level of acidity of a target and can be used to determine specific changes in the environment of a target, the fluid conditions surrounding a target, or the state of an operational fluid such as a coolant or lubricant in a target, and similarly, fluid, and gaseous chemical sensors perform additional component and presence detection on these targets. A lubricant sensor can be as simple as an indicator of whether sufficient lubricant is still present (by detecting chafing or a lack of distance between conductive or hard components) or can use a combination of chemical, pressure, visual, olfactory, or vibrational feedback tests (vibrating the target and measuring response) to determine the instant or continuous presence or quantity of lubricant in a target. Contaminant sensors can look for the presence of foreign or damaged elements added to the surface, substance or fluid contents of a target, such as a lubricant which has been contaminated with metal particles from component wear, or when a lubricant or motive fluid such as in a pneumatic has been contaminated due to the breaking of a seal. Particulate sensors can detect the presence of specific types of particles within a fluid or on a target. Weight or mass sensors can determine the continuous or changing weight of a component, and can be on coarse scale such as a weighing device for weighing large machinery down to an integrated MEMS scale that determines the continuous and instantaneous changes in weight of a target that may lose mass over time due to damage or abrasion or evaporation, sublimation, etc. A rotation sensor can be optical, audio-based, or use numerous other techniques to detect the periodic acceleration, velocity, and frequency of rotation of a target. Temperature sensors can be configured to measure coarse environmental temperature in a general area as well as fine environmental temperatures, precise temperature of a region of a target component and can be disposed throughout an engine, a robotic system, or any stationary or moving component. Temperature sensors can also be mobile and deployed to take periodic or ad-hoc measurements of a target component, surface, material, or system to determine if it is operating in a correct temperature range. Position sensors can be as simple as interrupted visual reflections, to visual systems with image-recognition algorithms being performed on continuous video, to magnetic or mechanical switch systems that durably detect either precisely or coarsely the position of various moveable elements with respect to one another. Ultrasonic sensors can be used for a variety of distance, shape, solidity, and orientation measurements by projecting ultrasonic energy in the direction of a target or group of targets or measuring the reflected ultrasonic energy reflected by those targets. Ultrasonic sensors may comprise multiple emitters and receivers in order to add dimensions and precision to the measurements and even produce 2D or 3D outlines of a region for further analysis. A radiation sensor can detect the presence of forms of radioactivity as alpha, beta, gamma, or x-ray radiation and some can identify the directional source, the field and area of the radiation and the intensity. An x-ray radiograph can actively determine structure, structural changes and structural defects as well as providing a visual depiction of otherwise obscured physical characteristics of a target. Similarly, a gamma-ray radiograph can be used to penetrate solid targets such as steel or other metallic objects and so determine the characteristics of physical features such as joints, welds, depths, rough edges, and thicknesses in load bearing and pressurized targets. Various forms of high-resolution scanning technologies exist including scanning tunneling microscopes, photon tunneling microscope, scanning probe microscopes, and these measurement devices have been miniaturized and non-destructive forms of these devices can be brought in contact with a target to be measured, such as via a movable robot or drone 11730, and then used to perform extremely high resolution (atomic-scale) measurements and analysis of the structure and characteristics of a target. A displacement meter can be implemented using capacitive effects, mechanical measurement or laser measurement and can be used similarly to a position meter to measure the location of a movable target and can be used, for instance, to measure the ‘play’ or changing displacement of a wearing physical target over time. A magnetic particle inspector can be used to determine if a fluid such as a lubricant, an immersive fluid container, a coolant, or a pneumatic fluid, for instance, contain trace elements of ferromagnetic particles, which could be an indication of the decay or failure of a metal component. An ultraviolet particle detector can be used to detect contamination such as in gaseous targets. A load sensor such as a static load sensor (measuring systems at rest) or an axial load sensor that detects, such as magnetically, the pushing and pulling forces along a beam and can be used to determine the forces on an axle or other torque-transmitting tube or shaft. An accelerometer can be microscopic in size, implemented as a MEMS device, or packaged as a larger industrial device and can provide multiple dimensions of acceleration and gravitation data about or in proximity to a target, and can be useful for instance to detect if a device is level, or in addition to other data collection, the amount of force being applied to a target over time. A speed sensor can be used to measure translational, displacement or rotational velocity or speed. A rotational sensor can be used to measure the speed, period, frequency, even or uneven motion of a rotating element such as a tire, a gear, an armature, or a gyro. A moisture sensing device can detect the liquid, condensation or H2O content of the target or its environment. A humidity sensor can measure the degree of water vapor in the atmosphere in the vicinity of a target. Ammeters, voltmeters, flux meters, and electric field detectors can be used to measure electromagnetic effects, fields and levels of a target or in the vicinity of a target, or the electronic or magnetic emission of a target, or the potential energy stored in a target. A gear box sensor can measure numerous attributes of an industrial gear box for general translation of motive power in a robotic or assembly line environment as well as numerous complex vehicular gear assemblies including vehicle transmissions and differentials Measurements can include the precise position of all internal gears, the state of wear of gear elements and teeth, various chemical, temperature, pressure, contamination, coolant level, fluid level, vacuum level, seal level, torsion, torque, force, shear stress, cycle count, tooth gap, wear, and any other changing physical attribute. A gear wear sensor and “tooth decay” sensor can specifically measure and convey the degree to which gears have worn down or that the teeth of the gears have been chipped, cracked, flaked off or otherwise reduced from original condition, and this can be accomplished through visual or other emitting signal sensors, audio sensors (measuring change in sonic quality based on the change in impact of teeth), laser sensors (measuring the periodic interruption of a precise beam across each gear path), power transmission measurement (measuring loss of power from one gear to the next via torque or force measurement) and numerous other techniques. A transmission input speed sensor measures the rotational velocity of the shaft entering the transmission and can do this with rotational position sensors plotted against time. Transmission output speed sensors measure the rotational velocity of the shaft delivering motive force out of the transmission. A manifold airflow sensor or mass air flow sensor can be used to measure the air density or intake airflow of an engine and thus determine the amount of engine load, torque, or power output. Other types of engine load sensors can be used to determine how much power or torque is being delivered from an engine, such as by measuring the delivered axle speed vs. the expected axle speed or by measuring the work being produced. A throttle position sensor measures the position of an engine throttle regulating the amount of fuel and air entering an engine, and can be measured using various techniques such as hall effect sensing, inductive, mechanical position sensing, magneto resistive sensing, and other techniques. A coolant temperature sensor measures the coolant temperature in various positions, over time or instantaneously in a liquid or gas cooled target system. A speed sensor can measure rotational or linear speed or speed of an overall vehicle over a path or a moving part in rotational or translational motion. A brake sensor can measure various aspects of a vehicular or robotic braking system the degree to which a brake activation switch (such as a vehicular brake pedal) is depressed, or the degree to which a brake is activated or the degree to which a brake is making frictional or other speed-suppressing contact with the motion system. A fluid temperature sensor can measure the temperature of any fluid such as a gaseous, pressurized, lubricant, cooling, fuel, or transported substance and can measure it in a single location or in various locations throughout the body of the fluid, and such measurements can be achieved through integrated contact sensors, dispersed contact sensors around the perimeter of a container, or through active or passive measurement such as infrared sensing or measuring the effect of applied energy to a portion of a fluid and the reflected or measured effect, such as with a laser thermometer. An emitting thermometer tool can be directed to various portions of a three-dimensional fluid chamber to be measured. A tool load sensor can be used to determine the amount of power being delivered from a tool and the resistance of the moving parts against the expected unloaded power of that device. A bearing sensor can measure the forces in portions or throughout or at periodic intervals in a bearing and thus allow a system to measure the change in these forces over time, as well as measure other aspects of a mechanical bearing such as position, service life, rotational count, change in average velocity, sonic changes, vibrational changes, chemical changes, color changes, surface changes, contamination changes, and numerous other attributes relevant to change of the bearing and its potential performance over time. A standstill counter can measure when and how often and for how long and how rapidly a movable target is stationary and in what internal position (as in a rotational or movable element) or relative position (as in a device that interfaces with another device) the moveable target is holding still, which can amongst other things indicate a location where a device, by sitting in that specific position may develop a fault or unwanted physical asymmetry. A hydraulic pump or power unit sensor can sense the pressure within the hydraulic fluid that provides power and also help detect, based on non-linearity or other specific signals that the hydraulic fluid is aged, compromised, contaminated, oxygenated or otherwise at fault. Hydraulic pump and power unit sensors can also sense other aspects of a pump or power unit including service duration, displacement, current position, divergence from duty cycle, change in range of motion or velocity curve of motion over time, resistance, fluid temperatures and chemical state of the fluid enclosure, enclosure integrity, and other intrinsic aspects of the pump.

A chemical analysis sensor can use consumable or permanent sensors to analyze a sample and determine the presence of a single chemical molecule or element or the composition of a sample and the specific multiple chemicals that make it up and their relative quantities. Chemical analysis sensors use various techniques including spectral analysis, exposure to lights, combination with consumable test strips, solid-state chemical sensors, and other techniques to establish the chemical makeup of a target. Pressure detectors can detect the pressure in an environment (such as barometric pressure) or can be movably linked to an openable shaft such as with an inflatable object or tire with a tire stem or a pneumatic device or a gas-filled device such as a refrigerant unit, and can measure the pressure therein. Pressure detectors can also be permanently installed within a compressed or vacuum chamber and communicate their measurements through a wired or wireless channel. A vacuum detector can measure the level the relative state of pressure of the interior and can also produce a result simply indicative of whether a predetermined level of vacuum exists in a chamber.

Disclosed herein are methods and systems for data collection in an industrial environment featuring self-organization functionality. Such data collection systems and methods may facilitate intelligent, situational, context-aware collection, summarization, storage, processing, transmitting, and/or organization of data, such as by one or more data collectors (such as any of the wide range of data collector embodiments described throughout this disclosure), a central headquarters or computing system, and the like. The described self-organization functionality of data collection in an industrial environment may improve various parameters of such data collection, as well as parameters of the processes, applications, and products that depend on data collection, such as data quality parameters, consistency parameters, efficiency parameters, comprehensiveness parameters, reliability parameters, effectiveness parameters, storage utilization parameters, yield parameters (including financial yield, output yield, and reduction of adverse events), energy consumption parameters, bandwidth utilization parameters, input/output speed parameters, redundancy parameters, security parameters, safety parameters, interference parameters, signal-to-noise parameters, statistical relevancy parameters, and others. The self-organization functionality may optimize across one or more such parameters, such as based on a weighting of the value of the parameters; for example, a swarm of data collectors may be managed (or manage itself) to provide a given level of redundancy for critical data, while not exceeding a specified level of energy usage, e.g., per data collector or a group of data collectors or the entire swarm of data collectors. This may include using a variety of optimization techniques described throughout this disclosure and the documents incorporated herein by reference.
In embodiments, such methods and systems for data collection in an industrial environment can include one or more data collectors, e.g., arranged in a cooperative group or “swarm” of data collectors, that collect and organize data in conjunction with a data pool in communication with a computing system, as well as supporting technology components, services, processes, modules, applications and interfaces, for managing the data collection (collectively referred to in some cases as a data collection system 12004). Examples of such components include, but are not limited to, a model-based expert system, a rule-based expert system, an expert system using artificial intelligence (such as a machine learning system, which may include a neural net expert system, a self-organizing map system, a human-supervised machine learning system, a state determination system, a classification system, or other artificial intelligence system), or various hybrids or combinations of any of the above. References to a self-organizing method or system should be understood to encompass utilization of any one of the foregoing or suitable combinations, except where context indicates otherwise.
The data collection systems and methods of the present disclosure can be utilized with various types of data, including but not limited to vibration data, noise data and other sensor data of the types described throughout this disclosure. Such data collection can be utilized for event detection, state detection, and the like, and such event detection, state detection, and the like can be utilized to self-organize the data collection systems and methods, as further discussed herein. The self-organization functionality may include managing data collector(s), both individually or in groups, where such functionality is directed at supporting an identified application, process, or workflow, such as confirming progress toward or/alignment with one or more objectives, goals, rules, policies, or guidelines. The self-organization functionality may also involve managing a different goal/guideline, or directing data collectors targeted to determining an unknown variable based on collection of other data (such as based on a model of the behavior of a system that involves the variable), selecting preferred sensor inputs among available inputs (including specifying combinations, fusions, or multiplexing of inputs), and/or specifying a specific data collector among available data collectors.
A data collector may include any number of items, such as sensors, input channels, data locations, data streams, data protocols, data extraction techniques, data transformation techniques, data loading techniques, data types, frequency of sampling, placement of sensors, static data points, metadata, fusion of data, multiplexing of data, self-organizing techniques, and the like as described herein. Data collector settings may describe the configuration and makeup of the data collector, such as by specifying the parameters that define the data collector. For example, data collector settings may include one or more frequencies to measure. Frequency data may further include at least one of a group of spectral peaks, a true-peak level, a crest factor derived from a time waveform, and an overall waveform derived from a vibration envelope, as well as other signal characteristics described throughout this disclosure. Data collectors may include sensors measuring or data regarding one or more wavelengths, one or more spectra, and/or one or more types of data from various sensors and metadata. Data collectors may include one or more sensors or types of sensors of a wide range of types, such as described throughout this disclosure and the documents incorporated by reference herein. Indeed, the sensors described herein may be used in any of the methods or systems described throughout this disclosure. For example, one sensor may be an accelerometer, such as one that measures voltage per G of acceleration (e.g., 100 mV/G, 500 mV/G, 1 V/G, 5 V/G, 10 V/G). In embodiments, a data collector may alter the makeup of the subset of the plurality of sensors used in a data collector based on optimizing the responsiveness of the sensor, such as for example choosing an accelerometer better suited for measuring acceleration of a lower speed gear system or drill/boring device versus one better suited for measuring acceleration of a higher speed turbine in a power generation environment. Choosing may be done intelligently, such as for example with a proximity probe and multiple accelerometers disposed on a specific target (e.g., a gear system, drill, or turbine) where while at low speed one accelerometer is used for measuring in the data collector and another is used at high speeds. Accelerometers come in various types, such as piezo-electric crystal, low frequency (e.g., 10 V/G), high speed compressors (10 MV/G), MEMS, and the like. In another example, one sensor may be a proximity probe which can be used for sleeve or tilt-pad bearings (e.g., oil bath), or a velocity probe. In yet another example, one sensor may be a solid state relay (SSR) that is structured to automatically interface with another routed data collector (such as a mobile or portable data collector) to obtain or deliver data. In another example, a data collector may be routed to alter the makeup of the plurality of available sensors, such as by bringing an appropriate accelerometer to a point of sensing, such as on or near a component of a machine. In still another example, one sensor may be a triax probe (e.g., a 100 MV/G triax probe), that in embodiments is used for portable data collection. In some embodiments, of a triax probe, a vertical element on one axis of the probe may have a high frequency response while the ones mounted horizontally may influence limit the frequency response of the whole triax. In another example, one sensor may be a temperature sensor and may include a probe with a temperature sensor built inside, such as to obtain a bearing temperature. In still additional examples, sensors may be ultrasonic, microphone, touch, capacitive, vibration, acoustic, pressure, strain gauges, thermographic (e.g., camera), imaging (e.g., camera, laser, IR, structured light), a field detector, an EMI′ meter to measure an AC electromagnetic field, a gaussmeter, a motion detector, a chemical detector, a gas detector, a CBRNE detector, a vibration transducer, a magnetometer, positional, location-based, a velocity sensor, a displacement sensor, a tachometer, a flow sensor, a level sensor, a proximity sensor, a pH sensor, a hygrometer/moisture sensor, a densitometric sensor, an anemometer, a viscometer, or any analog industrial sensor and/or digital industrial sensor. In a further example, sensors may be directed at detecting or measuring ambient noise, such as a sound sensor or microphone, an ultrasound sensor, an acoustic wave sensor, and an optical vibration sensor (e.g., using a camera to see oscillations that produce noise). In still another example, one sensor may be a motion detector.
Data collectors may be of or may be configured to encompass one or more frequencies, wavelengths or spectra for particular sensors, for particular groups of sensors, or for combined signals from multiple sensors (such as involving multiplexing or sensor fusion). Data collectors may be of or may be configured to encompass one or more sensors or sensor data (including groups of sensors and combined signals) from one or more pieces of equipment/components, areas of an installation, disparate but interconnected areas of an installation (e.g., a machine assembly line and a boiler room used to power the line), or locations (e.g., a building in one geographic location and a building in a separate, different geographic location). Data collector settings, configurations, instructions, or specifications (collectively referred to herein using any one of those terms) may include where to place a sensor, how frequently to sample a data point or points, the granularity at which a sample is taken (e.g., a number of sampling points per fraction of a second), which sensor of a set of redundant sensors to sample, an average sampling protocol for redundant sensors, and any other aspect that would affect data acquisition.
Within the data collection system 12004, the self-organization functionality can be implemented by a neural net, a model-based system, a rule-based system, a machine learning system, and/or a hybrid of any of those systems. Further, the self-organizing functionality may be performed in whole or in part by individual data collectors, a collection or group of data collectors, a network-based computing system, a local computing system comprising one or more computing devices, a remote computing system comprising one or more computing devices, and a combination of one or more of these components. The self-organization functionality may be optimized for a particular goal or outcome, such as predicting and managing performance, health, or other characteristics of a piece of equipment, a component, or a system of equipment or components. Based on continuous or periodic analysis of sensor data, as patterns/trends are identified, or outliers appear, or a group of sensor readings begin to change, etc., the self-organization functionality may modify the collection of data intelligently, as described herein. This may occur by triggering a rule that reflects a model or understanding of system behavior (e.g., recognizing a shift in operating mode that calls for different sensors as velocity of a shaft increases) or it may occur under control of a neural net (either in combination with a rule-based approach or on its own), where inputs are provided such that the neural net over time learns to select appropriate collection modes based on feedback as to successful outcomes (e.g., successful classification of the state of a system, successful prediction, successful operation relative to a metric). For example only, when an assembly line is reconfigured for a new product or a new assembly line is installed in a manufacturing facility, data from the current data collector(s) may not accurately predict the state or metric of operation of the system, thus, the self-organization functionality may begin to iterate to determine if a new data collector, type of sensed data, format of sensed data, etc. is better at predicting a state or metric. Based on offset system data, such as from a library or other data structure, certain sensors, frequency bands or other data collectors may be used in the system initially and data may be collected to assess performance. As the self-organization functionality iterates, other sensors/frequency bands may be accessed to determine their relative weight in identifying performance metrics. Over time, a new frequency band may be identified (or a new collection of sensors, a new set of configurations for sensors, or the like) as a better or more suitable gauge of performance in the system and the self-organization functionality may modify its data collector(s) based on this iteration. For example only, perhaps an older boring tool in an energy extraction environment dampens one or more vibration frequencies while a different frequency is of higher amplitude and present during optimal performance than what was seen in the present system. In this example, the self-organization functionality may alter the data collectors from what was originally proposed, e.g., by the data collection system, to capture the higher amplitude frequency that is present in the current system.
The self-organization functionality, in embodiments involving a neural net or other machine learning system, may be seeded and may iterate, e.g., based on feedback and operation parameters, such as described herein. Certain feedback may include utilization measures, efficiency measures (e.g., power or energy utilization, use of storage, use of bandwidth, use of input/output use of perishable materials, use of fuel, and/or financial efficiency, financial such as reduction of costs), measures of success in prediction or anticipation of states (e.g., avoidance and mitigation of faults), productivity measures (e.g., workflow), yield measures, and profit measures. Certain parameters may include storage parameters (e.g., data storage, fuel storage, storage of inventory), network parameters (e.g., network bandwidth, input/output speeds, network utilization, network cost, network speed, network availability), transmission parameters (e.g., quality of transmission of data, speed of transmission of data, error rates in transmission, cost of transmission), security parameters (e.g., number and/or type of exposure events, vulnerability to attack, data loss, data breach, access parameters), location and positioning parameters (e.g., location of data collectors, location of workers, location of machines and equipment, location of inventory units, location of parts and materials, location of network access points, location of ingress and egress points, location of landing positions, location of sensor sets, location of network infrastructure, location of power sources), input selection parameters, data combination parameters (e.g., for multiplexing, extraction, transformation, loading), power parameters (e.g., of individual data collectors, groups of data collectors, or all potentially available data collectors), states (e.g., operational modes, availability states, environmental states, fault modes, health states, maintenance modes, anticipated states), events, and equipment specifications. With respect to states, operating modes may include, mobility modes (direction, speed, acceleration, and the like), type of mobility modes (e.g., rolling, flying, sliding, levitation, hovering, floating), performance modes (e.g., gears, rotational speeds, heat levels, assembly line speeds, voltage levels, frequency levels), output modes, fuel conversion modes, resource consumption modes, and financial performance modes (e.g., yield, profitability). Availability states may refer to anticipating conditions that could cause machine to go offline or require backup. Environmental states may refer to ambient temperature, ambient humidity/moisture, ambient pressure, ambient wind/fluid flow, presence of pollution or contaminants, presence of interfering elements (e.g., electrical noise, vibration), power availability, and power quality, among other parameters. Anticipated states may include achieving or not achieving a desired goal, such as a specified/threshold output production rate, a specified/threshold generation rate, an operational efficiency/failure rate, a financial efficiency/profit goal, a power efficiency/resource utilization, an avoidance of a fault condition (e.g., overheating, slow performance, excessive speed, excessive motion, excessive vibration/oscillation, excessive acceleration, expansion/contraction, electrical failure, running out of stored power/fuel, overpressure, excessive radiation/melt down, fire, freezing, failure of fluid flow (e.g., stuck valves, frozen fluids), mechanical failures (e.g., broken component, worn component, faulty coupling, misalignment, asymmetries/deflection, damaged component (e.g., deflection, strain, stress, cracking), imbalances, collisions, jammed elements, and lost or slipping chain or belt), avoidance of a dangerous condition or catastrophic failure, and availability (online status)).
The self-organization functionality may comprise or be seeded with a model that predicts an outcome or state given a set of data, which may comprise inputs from sensors, such as via a data collector, as well as other data, such as from system components, from external systems and from external data sources. For example, the model may be an operating model for an industrial environment, machine, or workflow. In another example, the model may be for anticipating states, for predicting fault, for optimizing maintenance, for optimizing data transport (such as for optimizing network coding, network-condition-sensitive routing), for optimizing data marketplaces, and the like.
The self-organization functionality may result in any number of downstream actions based on analysis of data from the data collector(s). In an embodiment, the self-organization functionality may determine that the system should either keep or modify operational parameters, equipment or a weighting of a neural net model given a desired goal, such as a specified/threshold output production rate, specified/threshold generation rate, an operational efficiency/failure rate, a financial efficiency/profit goal, a power efficiency/resource utilization, an avoidance of a fault condition, an avoidance of a dangerous condition or catastrophic failure, and the like. In embodiments, the adjustments may be based on determining context of an industrial system, such as understanding a type of equipment, its purpose, its typical operating modes, the functional specifications for the equipment, the relationship of the equipment to other features of the environment (including any other systems that provide input to or take input from the equipment), the presence and role of operators (including humans and automated control systems), and ambient or environmental conditions. For example, in order to achieve a profit goal in a distribution environment (e.g., a power distribution environment), a generator or system of generators may need to operate at a certain efficiency level. The self-organization functionality may be seeded with a model for operation of the system of generators in a manner that results in a specified profit goal, such as indicating an on/off state for individual generator(s) in the power generation system based on the time of day, current market sale price for the fuel consumed by the generators, current demand or anticipated future demand, and the like. As it acquires data and iterates, the model predicts whether the profit goal will be achieved given the current data, and determine whether the data or type of data being collected is appropriate, sufficient, etc. for the model. Based on the results of the iteration, a recommendation may be made (or a control instruction may be automatically provided) to gather different/additional data, organize the data differently, direct different data collectors to collect new data, etc. and/or to operate a subset of the generators at a higher output (but less efficient) rate, power on additional generators, maintain a current operational state, or the like. Further, as the system iterates, one or more additional sensors may be sampled in the model to determine if their addition to the self-organization functionality would improve predicting a state or otherwise assisting with the goals of the data collection efforts.
In embodiments, a system for data collection in an industrial environment may include a plurality of input sensors, such as any of those described herein, communicatively coupled to a data collector having one or more processors. The data collection system may include a plurality of individual data collectors structured to operate together to determine at least one subset of the plurality of sensors from which to process output data. The data collection system may also include a machine learning circuit structured to receive output data from the at least one subset of the plurality of sensors and learn received output data patterns indicative of a state. In some embodiments, the data collection system may alter the at least one subset of the plurality of sensors, or an aspect thereof, based on one or more of the learned received output data patterns and the state. In certain embodiments, the machine learning circuit is seeded with a model that enables it to learn data patterns. The model may be a physical model, an operational model, a system model, and the like. In other embodiments, the machine learning circuit is structured for deep learning wherein input data is fed to the circuit with no or minimal seeding and the machine learning data analysis circuit learns based on output feedback. For example, a metal tooling system in a manufacturing environment may operate to manufacture parts using machine tools such as lathes, milling machines, grinding machines, boring tools, and the like. Such machines may operate at various speeds and output rates, which may affect the longevity, efficiency, accuracy, etc. of the machine. The data collector may acquire various parameters to evaluate the environment of the machine tools, e.g., speed of operation, heat generation, vibration, and conformity with a part specification. The system can utilize such parameters and iterate towards a prediction of state, output rate, etc. based on such feedback. Further, the system may self-organize such that the data collector(s) collect additional/different data from which such predictions may be made.
There may be a balance of multiple goals/guidelines in the self-organization functionality of data collection system. For example, a repair and maintenance organization (RMO) may have operating parameters designed for maintenance of a machine in a manufacturing facility, while the owner of the facility may have particular operating parameters for the machine that are designed for meeting a production goal. These goals, in this example relating to a maintenance goal or a production output, may be tracked by a different data collectors or sensors. For example, maintenance of a machine may be tracked by sensors including a temperature sensor, a vibration transducer, and a strain gauge while the production goal of a machine may be tracked by sensors including a speed sensor and a power consumption meter. The data collection system may (optionally using a neural net, machine learning system, deep learning system, or the like, which may occur under supervision by one or more supervisors (human or automated) intelligently manage data collectors aligned with different goals and assign weights, parameter modifications, or recommendations based on a factor, such as a bias towards one goal or a compromise to allow better alignment with all goals being tracked, for example. Compromises among the goals delivered to the data collection system may be based on one or more hierarchies or rules relating to the authority, role, criticality, or the like of the applicable goals. In embodiments, compromises among goals may be optimized using machine learning, such as a neural net, deep learning system, or other artificial intelligence system as described throughout this disclosure. For example, in a power plant where a turbine is operating, the data collection system may manage multiple data collectors, such as one directed to detecting the operational status of the turbine, one directed at identifying a probability of hitting a production goal, and one directed at determining if the operation of the turbine is meeting a fuel efficiency goal. Each of these data collectors may be populated with different sensors or data from different sensors (e.g., a vibration transducer to indicate operational status, a flow meter to indicate production goal, and a fuel gauge to indicate a fuel efficiency) whose output data are indicative of an aspect of a particular goal. Where a single sensor or a set of sensors is helpful for more than one goal, overlapping data collectors (having some sensors in common and other sensors not in common) may take input from that sensor or set of sensors, as managed by the data collection system. If there are constraints on data collection (such as due to power limitations, storage limitations, bandwidth limitations, input/output processing capabilities, or the like), a rule may indicate that one goal (e.g., a fuel utilization goal or a pollution reduction goal that is mandated by law or regulation) takes precedence, such that the data collection for the data collectors associated with that goal are maintained as others are paused or shut down. Management of prioritization of goals may be hierarchical or may occur by machine learning. The data collection system may be seeded with models, or may not be seeded at all, in iterating towards a predicted state (e.g., meeting a goal) given the current data it has acquired. In this example, during operation of the turbine the plant owner may decide to bias the system towards fuel efficiency. All of the data collectors may still be monitored, but as the self-organization functionality iterates and predicts that the system will not collect or is not collecting data sufficient to determine whether the system is or is not meeting a particular goal, the data collection system may recommend or implement changes directed at collecting the appropriate data. Further, the plant owner may structure the system with a bias towards a particular goal such that the recommended changes to data collection parameters affecting such goal are made in favor of making other recommended changes.
In embodiments, the data collection system may continue iterating in a deep-learning fashion to arrive at a distribution of data collectors, after being seeded with more than one data collection data type, that optimizes meeting more than one goal. For example, there may be multiple goals tracked for a refining environment, such as refining efficiency and economic efficiency. Refining efficiency for the refining system may be expressed by comparing fuel put into the system, which can be obtained by knowing the amount of and quality of the fuel being used, and the amount of the refined product output from the system, which is calculated using the flow out of the system. Economic efficiency of the refining system may be expressed as the ratio between costs to run the system, including fuel, labor, materials and services, and the refined product output from the system for a period of time. Data used to track refining efficiency may include data from a flow meter, quality data point(s), and a thermometer, and data used to track economic efficiency may be a flow of product output from the system and costs data. These data may be used in the data collection system to predict states; however, the self-organization functionality of the system may iterate towards a data collection strategy that is optimized to predict states related to both thermal and economic efficiency. The new data collection schema may include data used previously in the individual data collectors but may also use new data from different sensors or data sources.
The iteration of the data collection system may be governed by rules, in some embodiments. For example, the data collection system may be structured to collect data for seeding at a pre-determined frequency. The data collection system may be structured to iterate at least a number of times, such as when a new component/equipment/fuel source is added, when a sensor goes off-line, or as standard practice. For example, when a sensor measuring the rotation of a boring tool in an offshore drilling operation goes off-line and the data collection system begins acquiring data from a new sensor or data collector measuring the same data points, the data collection system may be structured to iterate for a number of times before the state is utilized in or allowed to affect any downstream actions. The data collection system may be structured to train off-line or train in situ/online. The data collection system may be structured to include static and/or manually input data in its data collectors. For example, a data collection system associated with such a boring tool may be structured to iterate towards predicting a distance bored based on a duration of operation, wherein the data collector(s) include data regarding the speed of the boring tools, a distance sensor, a temperature sensor, and the like.
In embodiments, the data collection system may be overruled. In embodiments, the data collection system may revert to prior settings, such as in the event the self-organization functionality fails, such as if the collected data is insufficient or inappropriately collected, if uncertainty is too high in a model-based system, if the system is unable to resolve conflicting rules in rule-based system, or the system cannot converge on a solution in any of the foregoing. For example, sensor data on a power generation system used by the data collection system may indicate a non-operational state (such as a seized turbine), but output sensors and visual inspection, such as by a drone, may indicate normal operation. In this event, the data collection system may revert to an original data collection schema for seeding the self-organization functionality. In another example, one or more point sensors on a refrigeration system may indicate imminent failure in a compressor, but the data collector self-organized to collect data associated towards determining a performance metric did not identify the failure. In this event, the data collector(s) will revert to an original setting or a version of the data collector setting that would have also identified the imminent failure of the compressor.
In embodiments, the data collection system may change data collector settings in the event that a new component is added that makes the system closer to a different system. For example, a vacuum distillation unit is added to an oil and gas refinery to distill naphthalene, but the current data collector settings for the data collection system are derived from a refinery that distills kerosene. In this example, a data structure with data collector settings for various systems may be searched for a system that is more closely matched to the current system. When a new system is identified as more closely matched, such as one that also distill naphthalene, the new data collector settings (which sensors to use, where to direct them, how frequently to sample, what types of data and points are needed, etc. as described herein) are used to seed the data collection system to iterate towards predicting a state for the system. In embodiments, the data collection system may change data collector settings in the event that a new set of data is available from a third party library. For example, a power generation plant may have optimized a specific turbine model to operate in a highly efficient way and deposited the data collector settings in a data structure. The data structure may be continuously scanned for new data collectors that better aid in monitoring power generation and thus, result in optimizing the operation of the turbine.
In embodiments, the data collection system may utilize self-organization functionality to uncover unknown variables. For example, the data collection system may iterate to identify a missing variable to be used for further iterations. For example, an under-utilized tank in a legacy condensate/make-up water system of a power station may have an unknown capacity because it is inaccessible and no documentation exists on the tank. Various aspects of the tank may be measured by a swarm of data collectors to arrive at an estimated volume (e.g., flow into a downstream space, duration of a dye traced solution to work through the system), which can then be fed into the data collection system as a new variable.
In embodiments, the data collection system node may be on a machine, on a data collector (or a group of them), in a network infrastructure (enterprise or other), or in the cloud. In embodiments, there may be distributed neurons across nodes (e.g., machine, data collector, network, cloud).

In certain embodiments, one or more sensors and/or computing devices in the system 12200 are portable devices such as the user associated device 12216 associated with a user 12218, for example a plant operator walking through the industrial system may have a smart phone, which the system 12200 may selectively utilize as a data controller 12208, sensor 12206—for example to enhance communication throughput, sensor resolution, and/or as a primary method for communicating sensor data values 12244 to the controller 12212.

An example transmission condition 12254 includes a node in a mesh or hierarchical network detected as malicious (e.g., from another supervisory process, heuristically, or as indicated to the system 12200); a peer node has experienced a bandwidth or connectivity change 12296 (e.g., mesh network peer that was forwarding packets has lost connectivity, gained additional bandwidth, had a reduction in available bandwidth, and/or has regained connectivity). An example transmission condition 12254 includes a change in a cost of transmitting information 12298 (e.g., cost has increased or decreased, where cost may be a direct cost parameter such as a data transmission subscription cost, or an abstracted cost parameter reflecting overall system priorities, and/or a current cost of delivering information over a network hop has changed), a change has been made in a hierarchical network arrangement (e.g., network arrangement change 12300) such as to balance bandwidth use in a network tree; and/or a change in a permission scheme 12302 (e.g., a portion of the network relaying sampling data has had a change in permissions, authorization level, or credentials). Certain further example transmission conditions 12254 include the availability of an additional connection type 12304 (e.g., a higher-bandwidth network connection type has become available, and/or a lower-cost network connection type has become available); a change has been made in a network topology 12306 (e.g., a node has gone offline or online, a mesh change has occurred, and/or a hierarchy change has occurred); and/or a data collection client changed a preference or a requirement 12308 (e.g., a data frequency requirement for at least one of the number of sensor values; a data type requirement for at least one of the number of sensor values; a sensor target for data collection; and/or a data collection client has changed the storage target computing device, which may change the network delivery outcomes and routing).
The example controller 12212 includes a network management circuit 12230 that updates the sensor data transmission protocol 12232 in response to the transmission conditions 12254. For example, where the transmission conditions 12254 indicate that a current routing, protocol, delivery frequency, delivery rate, and/or any other parameter associated with communicating the sensor data 12252 is no longer cost effective, possible, optimal, and/or where an improvement is available, the network management circuit 12230 updates the sensor data transmission protocol 12232 in response to a lower cost, possible, optimal, and/or improved transmission condition. The example system collaboration circuit 12228 is further responsive to the updated sensor data transmission protocol 12232—for example, implementing subsequent communications of the sensor data 12252 in compliance with the updated sensor data transmission protocol 12232, providing a communication to the network management circuit 12230 indicating which aspects of the updated sensor data transmission protocol 12232 cannot be or are not being followed, and/or providing an alert (e.g., to an operator, a network node, controller 12212, and/or the network management circuit 12230) indicating that a change is requested, indicating that a change is being implemented, and/or indicating that a requested change cannot be or is not being implemented.

An example system further includes a data collector 12208 communicatively coupled to at least a portion of the number of sensors 12206 and responsive to the sensor data transmission protocol 12232, where the system collaboration circuit 12228 further receives the number of sensor data values 12244 from the at least a portion of the number of sensors, and where the transmission conditions 12254 correspond to at least one network parameter corresponding to the communication of the number of sensor data values from the at least a portion of the number of sensors.

An example network management circuit 12230 further updates the sensor data transmission protocol 12232 to adjust a network transmission parameter (e.g., any network parameter 12276) for at least a portion of the number of sensor values. For example, certain network parameters that are not control variables and/or are not currently being controlled are transmission conditions 12254, and certain network parameters are control variables and subject to change in response to the data transmission protocol 12232, and/or the network management circuit 12230 can optionally take control of certain network parameters to make them control variables. An example network management circuit 12230 further updates the sensor data transmission protocol 12232 to change any one or more of: a frequency of data transmitted; a quantity of data transmitted; a destination of data transmitted (including a target or intermediate destination, and/or a routing); a network protocol used to transmit the data; and/or a network path (e.g., providing a redundant path to transmit the data (e.g., where high noise, high network loss, and/or critical data are involved, the network management circuit 12230 may determine that the system operations are improved with redundant pathing for some of the data)). An example network management circuit 12230 further updates the sensor data transmission protocol 12232, such as to: bond an additional network path to transmit the data (e.g., the network management circuit 12230 may have authority to bring additional network resources online, and/or selectively access additional network resources); re-arrange a hierarchical network to transmit the data (e.g., add or remove a hierarchy layer, change a parent-child relationship, etc., for example, to provide critical data with additional paths, fewer layers, and/or a higher priority path); rebalance a hierarchical network to transmit the data; and/or reconfigure a mesh network to transmit the data. An example network management circuit 12230 further updates the sensor data transmission protocol 12232 to delay a data transmission time, and/or delay the data transmission time to a lower cost transmission time.
An example network management circuit further updates the sensor data transmission protocol 12232 to reduce the amount of information sent at one time over the network and/or updates the sensor data transmission protocol to adjust a frequency of data sent from a second data collector (e.g., an offset data collector within or not within the direct purview of the network management circuit 12230, but where network resource utilization from the second data collector competes with utilization of the first data collector).
An example network management circuit 12230 further adjusts an external data access frequency 12234—for example where the expert system 12242 and/or the machine learning algorithm 12248 access external data 12246 to make continuous improvements to the system (e.g., accessing information outside of the sensor data values 12244, and/or from offset systems or aggregated cloud based data), and/or an external data access timing (12236). The control of external data 12246 access allows for control of network utilization when the system is low on resources, when high fidelity and/or frequency of sensor data values 12244 is prioritized, and/or shifting of resource utilization into lower cost portions of the operating space of the system. In certain embodiments, the system collaboration circuit 12228 accesses the external data 12246, and is responsive to the adjusted external data access frequency 12234 and/or external data access timing value 12236. An example network management circuit 12230 further adjusts a network utilization value 12238—for example to keep system utilization operations below a threshold to reserve margin and/or to avoid the need for capital cost upgrades to the system due to capacity limitations. An example network management circuit 12230 adjusts the network utilization value 12238 to utilize bandwidth at a lower cost bandwidth time—for example when competing traffic is lower, when network utilization does not adversely affect other system processes, and/or when power consumption costs are lower.
An example network management circuit further 12230 enables utilizing a high-speed network, and/or requests a higher cost bandwidth access, for example when system process improvements are sufficient that higher costs are justified, to meet a minimum delivery requirement for data, and/or to move aging data from the system before it becomes obsolete or must be deleted to make room for subsequent data.
An example network management circuit 12230 further includes an expert system 12242, where the updating the sensor data transmission protocol 12232 is further in response to operations of the expert system 12242. The self-organized, network-sensitive data collection system may manage or optimize any such parameters or factors noted throughout this disclosure, individually or in combination, using an expert system, which may involve a rule-based optimization, optimization based on a model of performance, and/or optimization using machine learning/artificial intelligence, optionally including deep learning approaches, or a hybrid or combination of the above.

An example machine learning algorithm 12248 utilizes a machine learning optimization routine, and upon determining that an improved sensor data transmission protocol 12232 is available, the network management circuit 12230 provides the updated sensor data transmission protocol 12232 which is utilized by the system collaboration circuit 12228. In certain embodiments, the network management circuit 12230 may perform various operations such as supplying a sensor data transmission protocol 12232 which is utilized by the system collaboration circuit 12228 to produce real-world results, applies modeling to the system (either first principles modeling based on system characteristics, a model utilizing actual operating data for the system, a model utilizing actual operating data for an offset system, and/or combinations of these) to determine what an outcome of a given sensor data transmission protocol 12232 will be or would have been (including, for example, taking extra sensor data beyond what is utilized to support a process operated by the system, and/or utilizing external data 12246 and/or benchmarking data 12240), and/or applying randomized changes to the sensor data transmission protocol 12232 to ensure that an optimization routine does not settle into a local optimum or non-optimal condition.

An example system includes a mining operation, including a surface and/or underground mining operation. The example mining operation includes components such as an underground inspection system, pumps, ventilation, generators and/or power generation, gas composition or quality systems, and/or process stream composition systems (e.g., including determination of desired material compositions, and/or composition of effluent streams for pollution and/or regulatory control). Various sensors are present in an example system to support control of the operation, determine status of the components, support safe operation, and/or to support regulatory compliance. The sensor information is conveyed to a target storage system, including at least partially through a network communicatively coupled to the mining operation. In certain embodiments, the network infrastructure of the mining operation exhibits high variability, due to, without limitation, significant environmental variability (e.g., pit or shaft condition variability) and/or intermittent availability—e.g., shutting off electronics during certain mining operations, difficulty in providing network access to portions of the mining operation, and/or the desirability to include mobile or intermittently available devices within the network infrastructure. The example system includes a network management circuit that determines a sensor data transmission protocol to control flow of data from the sensors to the target storage system. The network management circuit, a related expert system, and/or a related machine learning algorithm, updates the sensor data transmission protocol to ensure efficient network utilization, sufficient delivery of data to support system control, diagnostics, improvement and/or efficiency updates to handling efficiency, support for financial and/or regulatory compliance, and/or other determinations planned for the data outside of the system, to reduce resource utilization of data transmission, and/or to respond to system noise factors, variability, network infrastructure challenges, and/or changes in the system or related aspects such as cost or environment parameters.
An example system includes an aerospace system, such as a plane, helicopter, satellite, space vehicle or launcher, orbital platform, and/or missile. Aerospace systems have numerous systems supported by sensors, such as engine operations, control surface status and vibrations, environmental status (internal and external), and telemetry support. Additionally, aerospace systems have high variability in both the number of sensors of varying types (e.g., a small number of fuel pressure sensors, but a large number of control surface sensors) as well as the sampling rates for relevant determinations of sensors of varying types (e.g., 1-second data may be sufficient for internal cabin pressure, but weather radar or engine speed sensors may require much higher time resolution). Computing power on an aerospace application is at a premium due to power consumption and weight considerations, and accordingly iterative, recursive, deep learning, expert system, and/or machine learning operations to improve any systems on the aerospace system, including sensor data taking and transmission of sensor information, are driven in many embodiments to computing devices outside of the aerospace vehicle of the system (e.g., through offline learning, post-processing, or the like). Storage capacity on an aerospace application is similarly at a premium, such that long-term storage of sensor data on the aerospace vehicle is not a cost-effective solution for many embodiments. Additionally, network communication from an aerospace vehicle may be subject to high variability and/or bandwidth limitations as the vehicle moves rapidly through the environment and/or into areas where direct communication with ground-based resources is not practical. Further, certain aerospace applications have significant competition for available network resources—for example in environments with a large number of passengers where passenger utilization of a network infrastructure consumes significant bandwidth. Accordingly, it can be seen that operations of a network management circuit, a related expert system, and/or a related machine learning algorithm, to update the sensor data transmission protocol can significantly enhance sensing operations in various aerospace systems. Additionally, certain aerospace applications have a high number of offset systems, enhancing the ability of an expert system or machine learning algorithm to improve sensor data capture and transmission operations, and/or to manage the high variability in sensed parameters (frequency, data rate, and/or data resolution) for the system across operating conditions.
An example system includes an oil or gas production system, such as a production platform (onshore or offshore), pumps, rigs, drilling equipment, blenders, and the like. Oil and gas production systems exhibit high variability in sensed variable types and sensing parameters, such as vibration (e.g., pumps, rotating shafts, fluid flow through pipes, etc.—which may be high frequency or low frequency), gas composition (e.g., of a wellhead area, personnel zone, near storage tanks, etc.—where low frequency may typically be acceptable, and/or it may be acceptable that no data is taken during certain times such as when personnel are not present), and/or pressure values (which may vary significantly both in required resolution and frequency or sampling rate depending upon operations currently occurring in the system). Additionally, oil and gas production systems have high variability in network infrastructure, both according to the system (e.g., an offshore platform versus a long-term ground-based production facility) and according to the operations being performed by the system (e.g., a wellhead in production may have limited network access, while a drilling or fracturing operation may have significant network infrastructure at a site during operations). Accordingly, it can be seen that operations of a network management circuit, a related expert system, and/or a related machine learning algorithm, to update the sensor data transmission protocol can significantly enhance sensing operations in various oil or gas production systems.

The example system 12500 further includes a sensor communication circuit 12522 (reference
In certain embodiments, sensor data values 12542 are provided to a data collector 12508, which may be in communication with multiple sensors 12506 and/or with a controller 12512. In certain embodiments, a plant computer 12510 is additionally or alternatively present. In the example system, the controller 12512 is structured to functionally execute operations of the sensor communication circuit 12522, sensor data storage profile circuit 12524, sensor data storage implementation circuit 12526, storage planning circuit 12528, and/or haptic feedback circuit 12530. The controller 12512 is depicted as a separate device for clarity of description. Aspects of the controller 12512 may be present on the sensors 12506, the data controller 12508, the plant computer 12510, and/or on a cloud computing device 12514. In certain embodiments described throughout this disclosure, all aspects of the controller 12512 or other controllers may be present in another device depicted on the system 12500. The plant computer 12510 represents local computing resources, for example processing, memory, and/or network resources, that may be present and/or in communication with the industrial system 12500. In certain embodiments, the cloud computing device 12514 represents computing resources externally available to the industrial system 12502, for example over a private network, intra-net, through cellular communications, satellite communications, and/or over the internet. In certain embodiments, the data controller 12508 may be a computing device, a smart sensor, a MUX box, or other data collection device capable to receive data from multiple sensors and to pass-through the data and/or store data for later transmission. An example data controller 12508 has no storage and/or limited storage, and selectively passes sensor data therethrough, with a subset of the sensor data being communicated at a given time due to bandwidth considerations of the data controller 12508, a related network, and/or imposed by environmental constraints. In certain embodiments, one or more sensors and/or computing devices in the system 12500 are portable devices—for example a plant operator walking through the industrial system may have a smart phone, which the system 12500 may selectively utilize as a data controller 12508, sensor 12506—for example to enhance communication throughput, sensor resolution, and/or as a primary method for communicating sensor data values 12542 to the controller 12512. The system 12500 depicts the controller 12512, the sensors 12506, the data controller 12508, the plant computer 12510, and/or the cloud computing device 12514 having a memory storage for storing sensor data thereon, any one or more of which may not have a memory storage for storing sensor data thereon. In certain embodiments, the sensor data storage profile circuit 12524 prepares a data storage profile 12532 that directs sensor data to memory storage, including moving sensor data in a controlled manner from one memory storage to another. Sensor data stored on various devices consumes memory on the device, transferring the stored data between device consumes network and/or communication bandwidth in the system 12500, and/or operations on sensor data such as processing, compression, statistical analysis, summarization, and/or provision of alerts consumes processor cycles as well as memory to support operations such as buffer files, intermediate data, and the like. Accordingly, improved or optimal configuration and/or updating of the data storage profile 12532 provides for lower utilization of system resources and/or allows for the storage of sensor data with higher resolution, over longer time frames, and/or from a larger number of sensors.

For example, data from a temperature sensor may be planned to be stored locally on a sensor having storage capacity, and transmitted in bursts to a data controller. The data controller may be instructed to transmit the sensor data to the cloud computing device on a schedule, for example as the data controller memory reaches a threshold, as network communication capacity is available, at the conclusion of a process, and/or upon request. Additionally or alternatively, data from the sensors may be changed on a device or upon transfer of the data (e.g., just before transfer, just after transfer, or on a schedule). For example, the data storage profile 12532 may describe storing high resolution, high precision, and/or high-sampling rate data, and reducing the storage of the data set after a period of time, a selected event, and/or confirmation of a successful process or that the high resolution data is no longer needed. Accordingly, higher resolution data and/or data from a large number of sensors may be available for utilization, such as by a sensor fusion operation or the like, while the long-term memory utilization is also managed. Each of the sensor data sets may be treated individually for memory storage characteristics, and/or sensors may be grouped for similar treatment (e.g., sensors having similar data characteristics and/or impact on the system, sensors cooperating in a sensor fusion operation, a group of sensors utilized for a model or a virtual sensor, etc.). In certain embodiments, sensor data from a single sensor may be treated distinctly according to an update of the data storage profile 12532, a time or process stage at which the data is taken, and/or a system condition such as a network issue, a fault condition, or the like. Additionally or alternatively, a single set of sensor data may be stored in multiple places in the system, for example where the same data is utilized in several separate sensor fusion operations, and the resource consumption from storing multiple sets of the same data is lower than a processor or network utilization to utilize a single stored data set in several separate processes.

An example controller 12512 includes the data storage profile 12532 including a data resolution description 12540 corresponding to at least one of the number of sensor data values 12544, where the data resolution description 12540 includes a value such as: a detection density value corresponding to the at least one of the number of sensor data values (e.g., detection density may be time sampling resolution, spatial sampling resolution, precision of the sampled data, and/or a processing operation to be applied that may affect the available resolution, such as filtering and/or lossy compression of the data); a detection density value corresponding to a more than one of the number of the sensor data values (e.g., a group of sensors having similar detection density values, a secondary data value determined from a group of sensors having a specified detection density value, etc.); a detection density trajectory including a number of detection density values of the at least one of the number of sensor data values, each of the number of detection density values corresponding to a time value (e.g., any of the detection density concepts combined with any of the time domain concepts); a detection density trajectory including a number of detection density values of the at least one of the number of sensor data values, each of the number of detection density values corresponding to a process stage value (e.g., any of the detection density concepts combined with any of the process description or stage concepts); and/or a detection density trajectory comprising a number of detection density values of the at least one of the number of sensor data values, each of the number of detection density values corresponding to a storage location value (e.g., detection density can be varied according to the device storing the data).

For example, during operations of a system at a first point in time, the sensor data storage implementation circuit 12526 utilizes a currently existing data storage profile sensor data storage implementation circuit 12526, which may be based on initial estimates of the system performance, desired data from an operator of the system, and/or from a previous operation of the sensor data storage profile circuit 12524. During operations of the system, the sensor data storage implementation circuit 12526 stores data according to the data storage profile 12532, and the sensor data storage profile circuit 12524 determines parameters for the data storage profile 12532 which may result in improved performance of the system.

In certain embodiments, the sensor data storage profile circuit 12524 may perform various operations such as supplying an intermediate data storage profile 12532 which is utilized by the sensor data storage implementation circuit 12526 to produce real-world results, applies modeling to the system (either first principles modeling based on system characteristics, a model utilizing actual operating data for the system, a model utilizing actual operating data for an offset system, and/or combinations of these) to determine what an outcome of a given data storage profile 12532 will be or would have been (including, for example, taking extra sensor data beyond what is utilized to support a process operated by the system), and/or applying randomized changes to the data storage profile 12532 to ensure that an optimization routine does not settle into a local optimum or non-optimal condition.

In embodiments, methods and systems are provided for data collection in or relating to one or more machines deployed in an industrial environment using self-organized network coding for network transmission of sensor data in a network. In embodiments, network coding may be used to specify and manage the manner in which packets (including streams of packets as noted in various embodiments disclosed throughout this disclosure and the documents incorporated by reference) are relayed from a sender (e.g., a data collector, instrumentation system, computer, or the like in an industrial environment where data is collected, such as from sensors or instruments on, in or proximal to industrial machines or from data storage in the environment) to a receiver (e.g., another data collector (such as in a swarm or coordinated group), instrumentation system, computer, storage, or the like in the industrial environment, or to a remote computer, server, cloud platform, database, data pool, data marketplace, mobile device (e.g., mobile phone, personal computer, tablet, or the like), or other network-connected device of system), such as via one or more network infrastructure elements (referred to in some cases herein as nodes), such as access points, switches, routers, servers, gateways, bridges, connectors, physical interfaces and the like, using one or more network protocols, such as IP-based protocols, TCP/IP, UDP, HTTP, Bluetooth, Bluetooth Low Energy, cellular protocols, LTE, 2G, 3G, 4G, 5G, CDMA, TDSM, packet-based protocols, streaming protocols, file transfer protocols, broadcast protocols, multi-cast protocols, unicast protocols, and others. For situations involving bi-directional communication, any of the above-referenced devices or systems, or others mentioned throughout this disclosure, may play the role of sender or receiver, or both. Network coding may account for availability of networks, including the availability of multiple alternative networks, such that a transmission may be delivered across different networks, either separated into different components or sending the same components redundantly Network coding may account for bandwidth and spectrum availability; for example, a given spectrum may be divided (such as with sub-dividing spectrum by frequency, by time-division multiplexing, and other techniques). Networks or components thereof may be virtualized, such as for purposes of provisioning of network resources, specification of network coding for a virtualized network, or the like. Network coding may include a wide variety of approaches as described in Appendix A, and in connection with Figures in Appendix A.
In embodiments, one or more network coding systems or methods of the present disclosure may use self-organization, such as to configure network coding parameters for one or more transmissions over one or more networks using an expert system, which may comprise a model-based system (such as automatically selecting network coding parameters or configuration based on one or more defined or measured parameters relating to a transmission, such as parameters of the data or content to be transmitted, the sender, the receiver, the available network infrastructure components, the conditions of the network infrastructure, the conditions of the industrial environment, or the like). A model may, for example, account for parameters relating to file size, numbers of packets, size of a stream, criticality of a data packet or stream, value of a packet or stream, cost of transmission, reliability of a transmission, quality of service, quality of transmission, quality of user experience, financial yield, availability of spectrum, input/output speed, storage availability, storage reliability, and many others as noted throughout this disclosure. In embodiments, the expert system may comprise a rule-based system, where one or more rules is executed based on detection of a condition or parameter, calculation of a variable, or the like, such as based on any of the above-noted parameters. In embodiments, the expert system may comprise a machine learning system, such as a deep learning system, such as based on a neural network, a self-organizing map, or other artificial intelligence approach (including any noted throughout this disclosure or the documents incorporated by reference). A machine learning system in any of the embodiments of this disclosure may configure one or more inputs, weights, connections, functions (including functions of individual neurons or groups of neurons in a neural net) or other parameters of an artificial intelligence system. Such configuration may occur with iteration and feedback, optionally involving human supervision, such as by feeding back various metrics of success or failure. In the case of network coding, configuration may involve setting one or more coding parameters for a network coding specification or plan, such as parameters for selection of a network, selection one or more nodes, selection of data path, configuration of timers or timing parameters, configuration of redundancy parameters, configuration of coding types (including use of regenerating codes, such as for use of network coding for distributed storage, such as in peer-to-peer networks, such as a peer-to-peer network of data collectors, or a storage network for a distributed ledger, as noted elsewhere in this disclosure), coefficients for coding (including linear algebraic coefficients), parameters for random or near-random linear network coding (including generation of near random coefficients for coding), session configuration parameters, or other parameters noted in the network coding embodiments described below, throughout this disclosure, and in the documents incorporated herein by reference. For example, a machine learning system may configure the selection of a protocol for a transmission, the selection of what network(s) will be used, the selection of one or more senders, the selection of one or more routes, the configuration of one or more network infrastructure nodes, the selection of a destination receiver, the configuration of a receiver, and the like. In embodiments, each one of these may be configured by an individual machine learning system, or the same system may configure an overall configuration by adjusting various parameters of one or more of the above under iteration, through a series of trials, optionally seeded by a training set, which may be based on human configuration of parameters, or by model-based and/or rule-based configuration. Feedback to a machine learning system may comprise various measures, including transmission success or failure, reliability, efficiency (including cost-based, energy-based and other measures of efficiency, such as measuring energy per bit transmitted, energy per bit stored, or the like), quality of transmission, quality of service, financial yield, operational effectiveness, success at prediction, success at classification, and others. In embodiments, a machine learning system may configure network coding parameters by predicting network behavior or characteristics and may learn to improve prediction using any of the techniques noted above. In embodiments, a machine learning system may configure network coding parameters by classification of one or more network elements and/or one or more network behaviors and may learn to improve classification, such as by training and iteration over time. Such machine-based prediction and/or classification may be used for self-organization, including by model-based, rule-based, and machine learning-based configuration. Thus, self-organization of network coding may use or comprise various combinations or permutations of model-based systems, rule-based systems, and a variety of different machine-learning systems (including classification systems, prediction systems, and deep learning systems, among others).

As described in US patent application 2017/0012861, entitled “Multi-path network communication,” self-organized network coding under control of an expert system may involve methods and systems for data communication between a first node and a second node over a number of data paths coupling the first node and the second node and may include transmitting messages between the first node and the second node over the number of data paths, including transmitting a first subset of the messages over a first data path of the number of data paths and transmitting a second subset of the messages over a second data path of the number of data paths. In situations where the first data path has a first latency and the second data path has a second latency substantially larger than the first latency, and messages of the first subset of the messages are chosen to have first message characteristics and messages of the second subset are chosen to have second message characteristics, different from the first message characteristics.
Messages having the first message characteristics, targeted for data paths of lower latency, may include time critical messages; for example, in an industrial environment, messages relating to a critical fault condition of a machine (e.g., overheating, excessive vibration, or any of the other fault conditions described throughout this disclosure) or relating to a safety hazard, or a time-critical operational step on which other processes depend (e.g., completion of a catalytic reaction, completion of a sub-assembly, or the like in a high-value, high-speed manufacturing process, a refining process, or the like) may be designated as time critical (such as by a rule that can be parsed or processed by a rules engine) or may be learned to be time-critical by the expert system, such as based on feedback regarding outcomes over time, including outcomes for similar machines having similar data in similar industrial environments. The first subset of the messages and the second subset of the messages may be determined from a portion of the messages available at the first node at a time of transmission. At a subsequent time of transmission, additional messages made available to the first node may be divided into the first subset and the second subset based on message characteristics associated with the additional messages. Division into subsets and selection of what subsets are targeted to what data path may be undertaken by an expert system. Messages having the first message characteristics may be associated with an initial subset of a data set and messages having the second message characteristics may be associated with a subsequent subset of the data set. The methods and systems described herein for selecting inputs for data collection and for multiplexing data may be organized, such as by an expert system, to configure inputs for the alternative channels, such as by providing streaming elements that have real-time significance to the first data path and providing other elements, such as for long-term, predictive maintenance, to the other data path. In embodiments, the messages of the second subset may include messages that are at most n messages ahead of a last acknowledged message in a sequential transmission order associated with the messages, wherein n is determined based on a buffer size at one of the first and second nodes.
Messages having the first message characteristics may include acknowledgement messages and messages having the second message characteristics may include data messages. Messages having the first message characteristics may include supplemental data messages. The supplemental data messages may include data messages may include redundancy data and messages having the second message characteristics may include original data messages. The first data path may include a terrestrial data path and the second data path may include a satellite data path. The terrestrial data path may include one or more of a cellular data path, a digital subscriber line (DSL) data path, a fiber optic data path, a cable internet based data path, and a wireless local area network data path. The satellite data path may include one or more of a low earth orbit satellite data path, a medium earth orbit satellite data path, and a geostationary earth orbit satellite data path. The first data path may include a medium earth orbit satellite data path or a low earth orbit satellite data path and the second data path may include a geostationary orbit satellite data path.
The method may further include, for each path of the number of data paths, maintaining an indication of successful and unsuccessful delivery of the messages over the data path and adjusting a congestion window for the data path based on the indication, which may occur under control of an expert system, including based on feedback of outcomes of a set of transmissions. The method may further include, for each path of the number of data paths, maintaining, at the first node, an indication of whether a number of messages received at the second node is sufficient to decode data associated with the messages, wherein the indication is based on feedback received at the first node over the number of data paths.
In another general aspect, a system for data communication between a number of nodes over a number of data paths coupling the number of nodes includes a first node configured to transmit messages to a second node over the number of data paths including transmitting a first subset of the messages over a first data path of the number of data paths, and transmitting a second subset of the messages over a second data path of the number of data paths.
In embodiments, the first subset of the messages and the second subset of the messages for the respective data paths may be determined from a portion of the messages available at a first node at a time of transmission. At a subsequent time of transmission, additional messages made available to the first node may be divided into a first subset and a second subset based on message characteristics associated with the additional messages. Messages having the first message characteristics may be associated with an initial subset of a data set and messages having the second message characteristics may be associated with a subsequent subset of the data set.
In embodiments, the messages of the second subset may include messages that are at most n messages ahead of a last acknowledged message in a sequential transmission order associated with the messages, wherein n is determined based on a receive buffer size at the second node. Messages having the first message characteristics may include acknowledgement messages and messages having the second message characteristics may include data messages. Messages having the first message characteristics may include supplemental data messages. The supplemental data messages may include data messages including redundancy data and messages having the second message characteristics may include original data messages.
The first node may be further configured to, for each path of the number of data paths, maintain an indication of successful and unsuccessful delivery of the messages over the data path and adjust a congestion window for the data path based on the indication. The first node may be further configured to maintain an aggregate indication of whether a number of messages received at the second node over the number of data paths is sufficient to decode data associated with the messages and to transmit supplemental messages based on the aggregate indication, wherein the aggregate indication is based on feedback from the second node received at the first node over the number of data paths.
The present disclosure describes a method for data communication between a first node and a second node over a plurality of data paths coupling the first node and the second node, the method according to one disclosed non-limiting embodiment of the present disclosure can include transmitting messages between the first node and the second node over the plurality of data paths including transmitting a first subset of the messages over a first data path of the plurality of data paths, and transmitting a second subset of the messages over a second data path of the plurality of data paths, wherein the first data path has a first latency and the second data path has a second latency substantially larger than the first latency, and messages of the first subset of the messages are chosen to have first message characteristics and messages of the second subset are chosen to have second message characteristics, different from the first message characteristics, wherein the selection of the first and second subset of message characteristics is performed automatically under control of an expert system.
A further embodiment of any of the foregoing embodiments of the present disclosure may include situations wherein the expert system uses at least one of a rule and a model to set a parameter of the selection.
A further embodiment of any of the foregoing embodiments of the present disclosure may include situations wherein the expert system is a machine learning system that iteratively configures at least one of a set of inputs, a set of weights, and a set of functions based on feedback relating to at least one of the data paths.
A further embodiment of any of the foregoing embodiments of the present disclosure may include situations wherein the expert system takes a plurality of inputs from a data collector that accepts data about a machine operating in an industrial environment.
As described in US patent application 2017/0012868, entitled “Multiple protocol network communication,” self-organized network coding under control of an expert system may involve methods and systems for data communication between a first node and a second node over one or more data paths coupling the first node and the second node and may include transmitting messages between the first node and the second node over the data paths, including transmitting at least some of the messages over a first data path using a first communication protocol, transmitting at least some of the messages over a second data path using a second communication protocol, determining that the first data path is altering a flow of messages over the first data path due to the messages being transmitted using the first communication protocol, and in response to the determining, adjusting a number of messages sent over the data paths, including decreasing a number of the messages transmitted over the first data path and increasing a number of messages transmitted over the second data path. Determination that the first data path is altering a flow of messages and/or adjusting the number of messages sent over the data paths may occur under control of an expert system, such as a rule-based system, a model-based system, a machine learning system (including deep learning) or a hybrid of any of those, where the expert system takes inputs relating to one or more of the data paths, the nodes, the communication protocols used, or the like. The data paths may be among devices and systems in an industrial environment, such as instrumentation systems of industrial machines, one or more mobile data collectors (optionally coordinated in a swarm), data storage systems (including network-attached storage), servers and other information technology elements, any of which may have or be associated with one or more network nodes. The data paths may be among any such devices and systems and devices and systems in a network of any kind (such as switches, routers, and the like) or between those and ones located in a remote environment, such as in an enterprise's information technology system, in a cloud platform, or the like.
Determining that the first data path is altering the flow of messages over the first data path may include determining that the first data path is limiting a rate of messages transmitted using the first communication protocol. Determining that the first data path is altering the flow of messages over the first data path may include determining that the first data path is dropping messages transmitted using the first communication protocol at a higher rate than a rate at which the second data path is dropping messages transmitted using the second communication protocol. The first communication protocol may be the User Datagram Protocol (UDP), and the second communication protocol may be the Transmission Control Protocol (TCP), or vice versa. Other protocols as described throughout this disclosure may be used.
The messages may be initially equally divided or divided according to some predetermined allocation (such as by type, as noted in connection with other embodiments) across the first data path and the second data path, such as using a load balancing technique. The messages may be initially divided across the first data path and the second data path according to a division of the messages across the first data path and the second data path in one or more prior data communication connections. The messages may be initially divided across the first data path and the second data path based on a probability that the first data path will alter a flow of messages over the first data path due to the messages being transmitted using the first communication protocol.
The messages may be divided across the first data path and the second data path based on message type. The message type may include one or more of acknowledgement messages, forward error correction messages, retransmission messages, and original data messages. Decreasing a number of the messages transmitted over the first data path and increasing a number of messages transmitted over the second data path may include sending all of the messages over the second path and sending none of the messages over the first path.
At least some of the number of data paths may share a common physical data path. The first data path and the second data path may share a common physical data path. The adjusting of the number of messages sent over the number of data paths may occur during an initial phase of the transmission of the messages. The adjusting of the number of messages sent over the number of data paths may repeatedly occur over a duration of the transmission of the messages. The adjusting of the number of messages sent over the number of data paths may include increasing a number of the messages transmitted over the first data path and decreasing a number of messages transmitted over the second data path.
In some examples, the parallel transmission over TCP and UDP is handled differently from conventional load balancing techniques, because TCP and UDP both share a low-level data path and nevertheless have very different protocol characteristics.
In some examples, approaches respond to instantaneous network behavior and learn the network's data handling policy and state by probing for changes. In an industrial environment, this may include learning policies relating to authorization to use aspects of a network; for example, a SCADA system may allow a data path to be used only by a limited set of authorized users, services, or applications, because of the sensitivity of underlying machines or processes that are under control (including remote control) via the SCADA system and concern over potential for cyberattacks. Unlike conventional load-balancers, which assume each data path is unique and does not affect the other, approaches may recognize that TCP and UDP share a low-level data path and directly affect each other. Additionally, TCP provides in-order delivery and retransmits data (along with flow control, congestion control, etc.) whereas UDP does not. This uniqueness requires additional logic provided by the methods and systems disclosed herein that may include mapping specific message types to each communication protocol, such as based at least in part on the different properties of the protocols (e.g., expect longer jitter over TCP, expect out-of-order delivery on UDP). For example, the system may refrain from coding over packets sent through TCP, since it is reliable, but may send forward error correction over UDP to add redundancy and save bandwidth. In some examples, a larger ACK interval is used for ACKing TCP data.
By employing the techniques described herein, approaches distribute data over TCP and UDP data paths to achieve optimal or near-optimal throughput, such as in situations where a network provider's policies treat UDP unfairly (as compared to conventional systems that simply use UDP if possible and fall back to TCP if not).

A further embodiment of any of the foregoing embodiments of the present disclosure may include situations wherein the probability is determined by an expert system.

The method may include receiving, at the first node, a feedback message from the second node indicating a missing message at the second node and, in response to receiving the feedback message, sending a redundancy message to the second node to increase a degree of redundancy associated with the missing message. The method may include maintaining, at the first node, a queue of preemptively computed redundancy messages and, in response to receiving the feedback message, removing some or all of the preemptively computed redundancy messages from the queue and adding the redundancy message to the queue for transmission.

The degree of redundancy associated with each of the messages may characterize a probability of correctability of an erasure of the message. The probability of correctability may depend on a comparison of between the degree of redundancy and a loss probability.

As described herein and in Appendix B attached hereto, intelligent industrial equipment and systems may be configured in various networks, including self-forming networks, private networks, Internet-based networks, and the like. One or more of the smart heating systems as described in Appendix B that may incorporate hydrogen production, storage, and use may be configured as nodes in such a network. In embodiments, a smart heating system may be configured with one or more network ports, such as a wireless network port that facilitate connection through Wi-Fi and other wired and/or wireless communication protocols as described. The smart heating system includes a smart hydrogen production system and a smart hydrogen storage system, and the like described in Appendix B and may be configured individually or as an integral system connected as one or more nodes in a network of industrial equipment and systems. By way of this example, a smart heating system may be disposed in an on-site industrial equipment operations center, such as a portable trailer equipped with communication capabilities and the like. Such deployed smart heating system may be configured, manually, automatically, or semi-automatically to join a network of devices, such as industrial data collection, control, and monitoring nodes and participate in network management, communication, data collection, data monitoring, control, and the like.
In another example of a smart heating system participating in a network of industrial equipment monitoring, control, and data collection devices in that a plurality of the smart heating systems may be configured into a smart heating system sub-network. In embodiments, data generated by the sub-network of devices may be communicated over the network of industrial equipment using the methods and systems described herein.
In embodiments, the smart heating system may participate in a network of industrial equipment as described herein. By way of this example, one or more of the smart heating systems, as depicted in
In embodiments, one or more smart heating systems described in Appendix B may incorporate, integrate, use, or connect with facilities, platforms, modules, and the like that may enable the smart heating system to perform functions such as analytics, self-organizing storage, data collection and the like that may improve data collection, deploy increased intelligence, and the like. Various data analysis techniques, such as machine pattern recognition of data, collection, generation, storage, and communication of fusion data from analog industrial sensors, multi-sensor data collection and multiplexing, self-organizing data pools, self-organizing swarm of industrial data collectors, and others described herein may be embodied in, enabled by, used in combination with, and derived from data collected by one or more of the smart heating systems.
In embodiments, a smart heating system may be configured with local data collection capabilities for obtaining long blocks of data (i.e., long duration of data acquisition), such as from a plurality of sensors, at a single relatively high-sampling rate as opposed to multiple sets of data taken at different sampling rates. By way of this example, the local data collection capabilities may include planning data acquisition routes based on historical templates and the like. In embodiments, the local data collection capabilities may include managing data collection bands, such as bands that define a specific frequency band and at least one of a group of spectral peaks, true-peak level, crest factor and the like.
In embodiments, one or more smart heating systems may participate as a self-organizing swarm of IoT devices that may facilitate industrial data collection. The smart heating systems may organize with other smart heating systems, IoT devices, industrial data collectors, and the like to organize among themselves to optimize data collection based on the capabilities and conditions of the smart heating system and needs to sense, record, and acquire information from and around the smart heating systems. In embodiments, one or more smart heating systems may be configured with processing intelligence and capabilities that may facilitate coordinating with other members, devices, or the like of the swarm. In embodiments, a smart heating system member of the swarm may track information about what other smart heating systems in a swarm are handling and collecting to facilitate allocating data collection activities, data storage, data processing and data publishing among the swarm members.
In embodiments, a plurality of smart heating systems may be configured with distinct burners but may share a common hydrogen production system and/or a common hydrogen storage system. In embodiments, the plurality of smart heating systems may coordinate data collection associated with the common hydrogen production and/or storage systems so that data collection is not unnecessarily duplicated by multiple smart heating systems. In embodiments, a smart heating system that may be consuming hydrogen may perform the hydrogen production and/or storage data collection so that as smart heating system may prepare to consume hydrogen, they coordinate with other smart heating systems to ensure that their consumption is tracked, even if another smart heating system performs the data collection, handling, and the like. In embodiments, smart heating systems in a swarm may communicate among each other to determine which smart heating system will perform hydrogen consumption data collection and processing when each smart heating system prepares to stop consumption of hydrogen, such as when heating, cooking, or other use of the heat is nearing completion and the like. By way of this example when a plurality of smart heating systems is actively consuming hydrogen, data collection may be performed by a first smart heating system, data analytics may be performed by a second smart heating system, and data and data analytics recording or reporting may be performed by a third smart heating system. By allocating certain data collection, processing, storage, and reporting functions to different smart heating systems, certain smart heating systems with sufficient storage, processing bandwidth, communication bandwidth, available energy supply and the like may be allocated an appropriate role. When a smart heating system is nearing an end of its heating time, cooking time, or the like, it may signal to the swarm that it will be going into power conservation mode soon and, therefore, it may not be allocated to perform data analysis or the like that would need to be interrupted by the power conservation mode.
In embodiments, another benefit of using a swarm of smart heating systems as disclosed herein is that data storage capabilities of the swarm may be utilized to store more information than could be stored on a single smart heating system by sharing the role of storing data for the swarm.
In embodiments, the self-organizing swarm of smart heating systems includes one of the systems being designated as a master swarm participant that may facilitate decision making regarding the allocation of resources of the individual smart heating systems in the swarm for data collection, processing, storage, reporting and the like activities.
In embodiments, the methods and systems of self-organizing swarm of industrial data collectors may include a plurality of additional functions, capabilities, features, operating modes, and the like described herein. In embodiments, a smart heating system may be configured to perform any or all of these additional features, capabilities, functions, and the like without limitation.

Various embodiments described in this document relate to communication protocols that improve aspects of communication between nodes on a data network. These aspects include, for instance, average, worst case, or variability in communication delay, channel utilization, and/or error rate. These embodiments are primarily described in the context of packet switched networks, and more particularly in the context of Internet Protocol (IP) based packet switched networks. However, it should be understood that at least some of the embodiments are more generally applicable to data communication that does not use packet switching or IP, for instance based on circuit-switched of other forms of data networks.
Furthermore, various embodiments are described in the context of data being sent from a “server” to a “client.” It should be understood that these terms are used very broadly, roughly analogous to “data source” and “data destination”. Furthermore, in at least some applications of the techniques, the nodes are peers, and may alternate roles as “server” and “client” or may have both roles (i.e., as data source and data destination) concurrently. However, for the sake of exposition, examples where there is a predominant direction of data flow from a “server” node to a “client” node are described with the understanding that the techniques described in these examples are applicable to many other situations.
One example for a client-server application involves a server passing multimedia (e.g., video and audio) data, either recorded or live, to a client for presentation to a user. Improved aspects of communication from the client to the server in such an example can reduced communication delay, for instance providing faster startup, reduced instances of interrupted playback, reduced instances of bandwidth reduction, and/or increased quality by more efficient channel utilization (e.g., by avoiding use of link capacity in retransmissions or unnecessary forward error correction). This example is useful for exposition of a number of embodiments. However, it must be recognized that this is merely one of many possible uses of the approached described below.

Generally, data units 201 (e.g., encoding of multimedia frames or other units of application data) generated by the server application 212 are passed to the TCP module 216. The TCP module assembles data payloads 202, for example, concatenating multiple data units 201 and/or by dividing data units 201 into multiple data payloads 202. In the discussion below, these payloads are referred to in some instances as the “original” or “uncoded” “packets” or original or uncoded “payloads”, which are communicated to the client (i.e., destination) node in the network. Therefore, it should be understood that the word “packet” is not used with any connotation other than being a unit of communication. In the TCP embodiment illustrated in
TCP implements a variety of features, including retransmission of lost packets, maintaining order of packets, and congestion control to avoid congestion at nodes or links along the path through the network and to provide fair allocation of the limited bandwidth between and within the networks at intermediate nodes. For example, TCP implements a “window protocol” in which only a limited number (or range of sequence numbers) of packets are permitted to be transmitted for which end-to-end acknowledgments have not yet been received. Some implementations of TCP adjust the size of the window, for example, starting initially with a small window (“slow start”) to avoid causing congestion. Some implementations of TCP also control a rate of transmission of packets, for example, according to the round-trip-time and the size of the window.
The description below details one or more alternatives to conventional TCP-based communication as illustrated in
It should also be understood that the network configuration illustrated in
A number of the alternatives to conventional TCP make use of a Packet Coding (PC) approach. Furthermore, a number of these approaches make use of Packet Coding essentially at the Transport Layer. Although different embodiments may have different features, these implementations are generically referred to below as Packet Coding Transmission Control Protocol (PC-TCP). Other embodiments are also described in which the same or similar PC approaches are used at other layers, for instance, at a data link layer (e.g., referred to as PC-DL), and therefore it should be understood that in general features described in the context of embodiments of PC-TCP may also be incorporated in PC-DL embodiments.
Before discussing particular features of PC-TCP in detail, a number of embodiments of overall system architectures are described. The later description of various embodiments of PC-TCP should be understood to be applicable to any of these system architectures, and others.
Referring to
One software implementation of the PC-TCP modules 316 or 326, is software modules that are integrated into the operating system (e.g., into the “kernel”, for instance, of a Unix-based operating system) in much the same manner that a conventional TCP module is integrated into the operating system. Alternative software implementations are discussed below.

Alternative Software Implementations
The description above includes modules generically labeled “PC-TCP”. In the description below, a number of different implementations of these modules are presented. It should be understood that, in general, any instance of a PC-TCP module may be implemented using any of the described or other approaches.

It should be understood that these software implementations are not exhaustive. Furthermore, as discussed further below, in some implementations, a PC-TCP module of any of the architectures or examples described in this document may be split among multiple hosts and/or network nodes, for example, using a proxy architecture.

It should be understood that the proxy architecture shown in
Referring to
In examples of the first alternative proxy node approach introduced above, communication between the client node and the proxy node uses conventional techniques (e.g., TCP/IP), while communication between the proxy node and the server node (or its proxy) uses PC-TCP 1127. Such an approach may mitigate congestion and/or packet error or loss on the link between the server node and the proxy node, however, it would not generally mitigate issues that arise on the link between the proxy node and the client node. For example, the client node and the proxy node may be linked by a wireless channel (e.g., WiFi, cellular, etc.), which may introduce a greater degree of errors than the link between the server and the proxy node over a wired network.
Referring to
Examples of such a proxy approach are illustrated in

Note that parameters of the two PC-TCP channels that are bridged at the intermediate node 1620 do not have to be the same. For example, the bridged channels may differ in their forward error correction code rate, block size, congestion window size, pacing rate, etc. In cases in which a retransmission protocol is used to address packet errors or losses that are not correctable with forward error correction coding, the PC-TCP modules at the intermediate node request or service such retransmission requests.

In general, the recoding PC-TCP module maintains separate communication characteristics on the inbound and outbound PC-TCP channels. Therefore, although it does not decode the payload data, it does provide control and, in general, the PC-TCP channels may differ in their forward error correction code rate, block size, congestion window size, pacing rate, etc.
In examples described above, a single path links the server node 111 and the client node 125. The possibility of using conventional TCP concurrently with PC-TCP between two nodes was introduced. More generally, communication between a pair of PC-TCP modules (i.e., one at the server node 111 and one at the client node 125) may follow different paths.
Internet protocol itself supports packets passing from one node to another following different paths and possibly being delivered out of order. Multiple data paths or channels can link a pair of PC-TCP modules and be used for a single session. Beyond native multi-path capabilities of IP networks, PC-TCP modules may use multiple explicit paths for a particular session. For example, without intending to be exhaustive, combinations of the following types of paths may be used:
Uncoded TCP and PC over UDP
PC over conventional TCP and UDP
PC-TCP over wireless LAN (e.g., WiFi, 802.11) and cellular data (e.g., 3G, LTE)
PC-TCP concurrently over multiple wireless base stations (e.g., via multiple wireless LAN access points)
In some examples, Network Coding is used such that the multiple paths from a server node to a client node pass through one or more intermediate nodes at which the data is recoded, thereby causing information for different data units to effectively traverse different paths through the network.
One motivation for multipath connection between a pair of endpoints addresses possible preferential treatment of TCP traffic rather than UDP traffic. Some networks (e.g. certain public Wi-Fi, cable television networks, etc.) may limit the rate of UDP traffic, or drop UDP packets preferentially compared to TCP (e.g., in the case of congestion). It may be desirable to be able to detect such scenarios efficiently without losing performance. In some embodiments, a PC-TCP session initially establishes and divides the transmitted data across both a TCP and a UDP connection. This allows comparison of the throughput achieved by both connections while sending distinct useful data on each connection. An identifier is included in the initial TCP and UDP handshake packets to identify the two connections as belonging to the same coded PC-TCP session, and non-blocking connection establishment can be employed so as to allow both connections to be opened at the outset without additional delay. The transmitted data is divided across the two connections using e.g. round-robin (sending alternating packets or runs of packets on each connection) or load-balancing/back pressure scheduling (sending each packet to the connection with the shorter outgoing data queue). Such alternation or load balancing can be employed in conjunction with techniques for dealing with packet reordering. Pacing rate and congestion window size can be controller separately for the UDP and the TCP connection, or can be controlled together. By controlling the two connections together (e.g., using only a single congestion window to regulate the sum of the number of packets in flight on both the TCP and UDP connections) may provide a greater degree of “fairness” as compared to separate control.
In some examples, the adjustment of the fraction of messages transmitted over each data path/protocol is determined according to the relative performance/throughput of the data paths/protocols. In some examples, the adjustment of allocation of messages occurs only during an initial portion of the transmission. In other examples, the adjustment of allocation of messages occurs on an ongoing basis throughout the transmission. In some examples, the adjustment reverses direction (e.g., when a data path stops preferentially dropping UDP messages, the number of messages transmitted over that data path may increase).
In some embodiments the PC-TCP maintains both the UDP based traffic and the TCP based traffic for the duration of the session. In other embodiments, the PC-TCP module compares the behavior of the UCP and TCP traffic, for example over a period specified in terms of time interval or number of packets, where these quantities specifying the period can be set as configuration parameters and/or modified based on previous coded TCP sessions, e.g. the comparison period can be reduced or eliminated if information on relative TCP/UDP performance is available from recent PC-TCP sessions. If the UDP connection achieves better throughput, the PC-TCP session can shift to using UDP only. If the TCP connection achieves better throughput, the PC-TCP session can shift to using TCP. In some embodiments, different types of traffic are sent over the TCP link rather than the UDP link. In one such example, the UDP connection is used to send some forward error correction for packets where it is beneficial to reduce retransmission delays, e.g. the last block of a file or intermediate blocks of a stream. In this example, the uncoded packets may be sent over a TCP stream with forward error correction packets sent over UDP. If the receiver can use the forward error correction packets to recover from erasures in the TCP stream, a modified implementation of the TCP component of the receiver's PC-TCP module may be able to avoid using a TCP-based error recovery procedure. On the other hand, non-delivery of a forward error correction packet does not cause an erasure of the data that is to be recovered at the receiver, and therefore unless there is an erasure both on the UDP path and on the TCP path, dropping of a UDP packet does not cause delay.
In some examples, multiple server nodes communicate with a client node. One way this can be implemented is with there being multiple communication sessions each involving one server node and one client node. In such an implementation, there is little or no interaction between a communication session between one server node and the client node and another communication session between another server node and the client node. In some examples, each server node may have different parts of a multimedia file, with each server providing its parts for combination at the client node.
In some examples, there is some relationship between the content provided by different servers to the client. One example of such a relationship is use of a distributed RAID approach in which redundancy information (e.g., parity information) for data units at one or more servers is stored at and provided from another server. In this way, should a data unit not reach the client node from one of the server nodes, the redundancy information may be preemptively sent or requested from the other node, and the missing data unit reconstructed.
In some examples, random linear coding is performed on data units before they are distributed to multiple server nodes as an alternative to use of distributed RAID. Then each server node establishes a separate communication session with the client node for delivery of part of the coded information. In some of these examples, the server nodes have content that has already been at least partially encoded and then cached, thereby avoiding the necessity of repeating that partial encoding for different client nodes that will received the same application data units. In some examples, the server nodes may implement some of the functionality of the PC modules for execution during communication sessions with client nodes, for example, having the ability to encode further redundancy information in response to acknowledgment information (i.e., negative acknowledgement information) received from a client node.
In some implementations, the multiple server nodes are content delivery nodes to which content is distributed using any of a variety of known techniques. In other implementations, these multiple server nodes are intermediary nodes at which content from previous content delivery sessions was cached and therefore available without requiring re-delivery of the content from the ultimate server node.
In some examples of distributed content delivery, each server to client connection is substantially independent, for example, with independently determined communication parameters (e.g., error correction parameters, congestion window size, pacing rate, etc.). In other examples, at least some of the parameters are related, for example, with characteristics determined on one server-to-client connection being used to determine how the client node communicates with other server nodes. For example, packet arrival rate, loss rate, and differences in one-way transmission rate, may be measured on one connections and these parameters may be used in optimizing multipath delivery of data involving other server nodes. One manner of optimization may involve load balancing across multiple server nodes or over communication links on the paths from the server nodes to the client nodes.
In some implementations, content delivery from distributed server nodes making use of PC-TCP, either using independent sessions or using coordination between sessions, may achieve the performance of conventional distributed content delivery but requiring a smaller number of server nodes. This advantage may arise due to PC-TCP providing lower latency and/or lower loss rates than achieved with conventional TCP.

The exemplary placements of networking devices in the communication scenarios described above should not be taken as limitations. It should be recognized that PC-TCP proxies can be placed in any network device and may support any type of data connection. That is, any type of end-user device, switching device, routing device, storage device, processing device and the like, may comprise PC-TCP proxies. Also PC-TCP proxies may reside only in the end-nodes of a communication path and/or only at two nodes along a connection path. However, PC-TCP proxies may also reside in more than two nodes of a communication path and may support multi-cast communications and multipath communications. PC-TCP proxies may be utilized in point-to-point communication networks, multi-hop networks, meshed networks, broadcast networks, storage networks, and the like.
Packet Coding (PC)
The description above focuses on architectures in which a packet coding approach is deployed, and in particular architectures in which a transport layer PC-TCP approach is used. In the description below, a number of features of PC-TCP are described. It should be understood that in general, unless otherwise indicated, these features are compatible with one another and can be combined in various combinations to address particular applications and situations.
As introduced above, data units (e.g., audio and/or video frames) are generally used to form data packets, for example, with one data unit per data packet, with multiple data units per data packet, or in some instances separating individual data units into multiple data packets. In some applications, the data units and associated data frames form a stream (e.g., a substantially continuous sequence made available over time without necessarily having groupings or boundaries in the sequence), while in other applications, the data units and associated data frames form one or more batches (e.g., a grouping of data that is required as a whole by the recipient).
In general, stream data is generated over time at a source and consumed at a destination, typically at a substantially steady rate. An example of a stream is a multimedia stream associated with person-to-person communication (e.g., a multimedia conference). Delay (also referred to as latency) and variability in delay (also referred to as jitter) are important characteristics of the communication of data units from a source to a destination.
An extreme example of a batch is delivery of an entire group of data, for example, a multiple gigabyte sized file. In some such examples, reducing the overall time to complete delivery (e.g., by maximizing throughput) of the batch is of primary importance. One example of batch delivery that may have very sensitive time (and real-time update) restraints is database replication.
In some applications, the data forms a series of batches that require delivery from a source to a destination Although delay in start of delivery and/or completion of delivery of a batch of data units may be important, in many applications overall throughput may be most important. An example of batch delivery includes delivery of portions of multimedia content, for instance, with each batch corresponding to sections of viewing time (e.g., 2 seconds of viewing time or 2 MB per batch), with content being delivered in batches to the destination where the data units in the batches are buffered and used to construct a continuous presentation of the content. As a result, an important consideration is the delivery of the batches in a manner than provides continuity between batches for presentation, without “starving” the destination application because a required batch has not arrived in time. In practice, such starving may cause “freezing” of video presentation in multimedia, which is a phenomenon that is all too familiar to today's users of online multimedia delivery. Another important consideration is reduction in the initial delay in providing the data units of the first batch to the destination application. Such delay is manifested, for example, in a user having to wait for initial startup of video presentation after selecting multimedia for online delivery. Another consideration in some applications is overall throughput. This may arise, for example, if the source application has control over a data rate of the data units, for example, being able to provide a higher fidelity version of the multimedia content if higher throughput can be achieved. Therefore, an important consideration may be providing a sufficiently high throughput in order to enable delivery of a high fidelity version of the content (e.g., as opposed to greatly compressed version or a backed-off rate of the content resulting in lower fidelity).
Various packet coding approaches described below, or selection of configuration parameters of those approaches, address considerations that are particularly relevant to the nature of the characteristics of the data being transported. In some examples, different approaches or parameters are set in a single system based on a runtime determination of the nature of the characteristics of the data being transported.
In general, the communication paths that link PC-TCP source and destination endpoints exhibit both relatively stationary or consistent channel characteristics, as well as transient characteristics. Relatively stationary or consistent channel characteristics can include, for example, capacity (e.g., maximum usable throughput), latency (e.g., transit time of packets from source to destination, variability in transit time), error rate (e.g., average packet erasure or error rate, burst characteristics of erasures/errors). In general, such relatively stationary or consistent characteristics may depend on the nature of the path, and more particularly on one or more of the links on the path. For example, a path with a link passing over a 4G cellular channel may exhibit very different characteristics than a path that passes over a cable television channel and/or a WiFi link in a home. As discussed further below, at least some of the approaches to packet coding attempt to address channel characteristic differences between types of communication paths. Furthermore, at least some of the approaches include aspects that track relatively slow variation in characteristics, for example, adapting to changes in average throughput, latency, etc.
Communication characteristics along a path may also exhibit substantial transient characteristics. Conventional communication techniques include aspects that address transient characteristics resulting from congestion along a communication path. It is well known that as congestion increases, for example at a node along a communication path, it is important that traffic is reduced at that node in order to avoid an unstable situation, for instance, with high packet loss resulting from buffer overruns, which then further increases data rates due to retransmission approaches. One common approach to addressing congestion-based transients uses an adaptive window size of “in flight” packets that have not yet been acknowledged by their destinations. The size of the window is adapted at each of the sources to avoid congestion-based instability, for example, by significantly reducing the size of the window upon detection of increased packet erasure rates.
In addressing communication over a variety of channels, it has been observed that transients in communication characteristics may not be due solely to conventional congestion effects, and that conventional congestion avoidance approaches may not be optimal or even desirable. Some effects that may affect communication characteristics, and that may therefore warrant adaptation of the manner in which data is transmitted can include one or more of the follow:
Effects resulting from cell handoff in cellular systems, including interruptions in delivery of packets or substantial reordering of packets delivered after handoff;
Effects resulting from “half-duplex” characteristics of certain wireless channels, for example, in WiFi channels in which return packets from a destination may be delayed until the wireless channel is acquired for upstream (i.e., portable device to access point) communication;
Effects of explicit data shaping devices, for example, intended to throttle certain classes of communication, for instance, based on a service provider's belief that that class of communication is malicious or is consuming more than a fair share of resources.
Although transient effects, which may not be based solely on congestion, may be tolerated using conventional congestion avoidance techniques, one or more of the approaches described below are particularly tailored to such classes of effects with the goal of maintaining efficient use of a channel without undue “over-reaction” upon detection of a transient situation, while still avoiding causing congestion-based packet loss.
In general, the coding approaches used in embodiments described in this document make use of inter-packet coding in which redundancy information is sent over the channel such that the redundancy information in one packet is generally dependent on a set of other packets that have been or will be sent over the channel. Typically, for a set of N packets of information, a total of N+K packets are sent in a manner that erasure or any K of the packets allows reconstruction of the original N packets of information. In general, a group of N information packets, or a group of N+K packets including redundancy information (depending on context), is referred to below as a “block” or a “coding block”. One example of such a coding includes N information packets without further coding, and then K redundancy packets, each of which depends on the N information packets. However it should be understood more than K of the packets (e.g., each of the N+K packets) may in some embodiments depend on all the N information packets.
Inter-packet coding in various embodiments described in this document use one or both of pre-emptive transmission of redundant packets, generally referred to as forward error correction (FEC), and transmission of redundant packets upon an indication that packets have or have a high probability of having been erased based on feedback, which is referred to below as repair and/or retransmission. The feedback for repair retransmission generally comes from the receiver, but more generally may come from a node or other channel element on the path to the receiver, or some network element having information about the delivery of packets along the path. In the FEC mode, K redundant packets may be transmitted in order to be tolerant of up to K erasures of the N packets, while in the repair mode, in some examples, for each packet that the transmitter believes has been or has high probability of having been erased, a redundant packet it transmitted from the transmitter, such that if in a block of N packets, K packets are believed to have been erased based on feedback, the transmitter sends at least an additional K packets.
As discussed more fully below, use of a forward error correction mode versus a repair mode represents a tradeoff between use of more channel capacity for forward error correction (i.e., reduced throughout of information) versus incurring greater latency in the presence of erasures for repair retransmission. As introduced above, the data characteristics being transmitted may determine the relative importance of throughput versus latency, and the PC-TCP modules may be configured or adapted accordingly.
If on average the packet erasure rate E is less than K/(N+K), then “on average” the N+K packets will experience erasure of K or fewer of the packets and the remaining packets will be sufficient to reconstruct the original N. Of course even if E is not greater than K/(N+K), random variability, non-stationarity of the pattern of erasures etc. results in some fraction of the sets of N+K packets having greater than K erasures, so that there is insufficient information to reconstruct the N packets at the destination. Therefore, even using FEC, at least some groups of N information packets will not be reconstructable. Note, for example, with E=0.2, N=8, and K=2, even though only 2 erasures may be expected on average, the probability of more than 2 erasures is greater than 30%, and even with E=0.1 this probability is greater than 7%, therefore the nature (e.g., timing, triggering conditions etc.) of the retransmission approaches may be significant, as discussed further below. Also as discussed below, the size of the set of packets that are coded together is significant. For example, increasing N by a factor of 10 to K+N=100 reduces the probably of more than the average number of 20 erasures (i.e., too many erasures to reconstruct the N=80 data packets) from over 7% to less than 0.1%.
Also as discussed further below, there is a tradeoff between use of large blocks of packets (i.e., large N) versus smaller blocks. For a particular code rate R=N/(N+K), longer blocks yield a higher probability of being able to fully recover the N information packets in the presence of random errors. Accordingly, depending on the data characteristics, the PC-TCP modules may be configured to adapt to achieve a desired tradeoff.
In general, in embodiments that guarantee delivery of the N packets, whether or not FEC is used, repair retransmission approaches are used to provide further information for reconstructing the N packets. In general, in preferred embodiments, the redundancy information is formed in such a manner that upon an erasure of a packet, the redundancy information that is sent from the transmitter does not depend on the specific packets that were erased, and is nevertheless suitable for repairing the erasure independent of which packet was erased.
In general, a preferred approach to inter-packet coding is based on Random Linear Network Coding (RLNC) techniques. However, it should be understood that although based on this technology, not all features that may be associated with this term are necessarily incorporated. In particular, as described above in the absence of intermediate nodes that perform recoding, there is not necessarily a “network” aspect to the approach. Rather, redundancy information is generally formed by combining the information packets into coded packets using arithmetic combinations, and more specifically, as sums of products of coefficients and representation of the information packets over arithmetic fields, such as finite fields (e.g., Galois Fields of order pn). In general, the code coefficients are chosen from a sufficiently large finite field in a random or pseudo-random manner, or in another way that the combinations of packets have a very low probability or frequency of being linearly dependent. The code coefficients, or a compressed version (e.g., as a reference into a table shared by the transmitter and receiver), are included in each transmitted combination of data units (or otherwise communicated to the receiver) and used for decoding at the receiver. Very generally, the original information packets may be recovered at a receiver by inverting the arithmetic combinations. For example, a version of Gaussian Elimination may be used to reconstruct the original packets from the coded combinations. A key feature of this approach is that for a set of N information packets, as soon at the receiver has at least N linearly independent combinations of those information packets in received packets, it can reconstruct the original data units. The term “degree of freedom” is generally used below to refer to a number of independent linear combinations, such that if N degrees of freedom have been specified for N original packets, then the N original packets can be reconstructed; while if fewer than N degrees of freedom are available, it may not be possible to fully reconstruct any of the N original packets. If N+K linearly independent linear combinations are sent, then any N received combinations (i.e., N received degrees of freedom) are sufficient to reconstruct the original information packets.
In some examples, the N+K linearly independent combinations comprise N selections of the N “uncoded” information packets (essentially N−1 zero coefficients and one unit coefficient for each uncoded packet), and K coded packets comprising the random arithmetic combination with N non-zero coefficients for the N information packets. The N uncoded packets are transmitted first, so that in the absence of erasures they should be completely received as soon as possible. In the case of one erasure of the original N packets, the receiver must wait for the arrival of one redundant packet (in addition to the N−1 original packets), and once that packet has arrived, the erased packet may be reconstructed. In the case of forward error correction, the K redundant packets follow (e.g., immediately after) the information packets, and the delay incurred in reconstructing the erased information packet depends on the transmission time of packets. In the case of repair retransmission, upon detection of an erasure or high probability of an erasure, the receiver provides feedback to the transmitter, which sends the redundancy information upon receiving the feedback. Therefore, the delay in being able to reconstruct the erased packet depends on the round-trip-time from the receiver to the transmitter and back.
As discussed in more detail below, feedback from the receiver to the transmitter may be in the form of acknowledgments sent from the receiver to the transmitter. This feedback in acknowledgements at least informs the transmitter of a number of the N+K packets of a block that have been successfully received (i.e., the number of received degrees of freedom), and may provide further information that depends on the specific packets that have been received at the receiver although such further information is not essential.
As introduced above, packets that include the combinations of original packets generally also include information needed to determine the coefficients used to combine the original packets, and information needed to identify which original packets were used in the combination (unless this set, such as all the packets of a block, is implicit). In some implementations, the coefficients are explicitly represented in the coded packets. In some embodiments, the coefficients are encoded with reference to shared information at the transmitter and the receiver. For instance, tables of pre-generated (e.g., random, pseudo random, or otherwise selected) coefficients, or sets of coefficients, may be stored and references into those tables are used to determine the values of the coefficients. The size of such a table determines the number of parity packets that can be generated while maintaining the linear independence of the sets of coefficients. It should be understood that yet other ways may be used to determine the coefficients.
Another feature of random linear codes is that packets formed as linear combinations of data units may themselves be additively combined to yield combined linear combinations of data units. This process is referred to in some instances as “recoding”, as distinct from decoding and then repeating encoding.
There are alternatives to the use of RLNC, which do not necessarily achieve similar optimal (or provably optimum, or near optimal) throughput as RLNC, but that give excellent performance in some scenarios when implemented as described herein. For example, various forms of parity check codes can be used. Therefore, it should be understood that RLNC, or any particular aspect of RLNC, is not an essential feature of all embodiments described in this document.
As introduced above, in at least some applications, data to be transmitted from a transmitter to a receiver forms a batch (i.e., as opposed to a continuous stream), with an example of a batch being a file or a segment (e.g., a two second segment of multimedia) of a file.
In an embodiment of the PC-TCP modules, the batch is transferred from the transmitter to the receiver as a series of blocks, with each block being formed from a series of information packets. In general, each block has the same number of information packets, however use of same size blocks is not essential.
The transmitter PC-TCP module generally receives the data units from the source application and forms the information packets of the successive blocks of the batch. These information packets are queued at the transmitter and transmitted on the channel to the receiver. In general, at the transmitter, the dequeueing and transmission of packets to the receiver makes use of congestion control and/or rate control mechanisms described in more detail below. The transmitter PC-TCP also retains the information packets (or sufficient equivalent information) to construct redundancy information for the blocks. For instance the transmitter PC-TCP buffers the information packets for each block for which there remains the possibility of an unrecovered erasure of a packet during transit from the transmitter to the receiver.
In general, the receiver provides feedback to the transmitter. Various approaches to determining when to provide the feedback and what information to provide with the feedback are described further below. The feedback provides the transmitter with sufficient information to determine that a block has been successfully received and/or reconstructed at the receiver. When such success feedback for a block has been received, the transmitter no longer needs to retain the information packets for the block because there is no longer the possibility that redundancy information for the block will need to be sent to the receiver.
The feedback from the receiver to the transmitter may also indicate that a packet is missing. Although in some cases the indication that a packet is missing is a premature indication of an erasure, in this embodiment the transmitter uses this missing feedback to trigger sending redundant information for a block. In some examples, the packets for a block are numbered in sequence of transmission, and the feedback represents the highest number received and the number of packets (i.e., the number of degrees of freedom) received (or equivalently the number of missing packets or remaining degrees of freedom needed) for the block. The transmitter addresses missing packet feedback for a block through the transmission of redundant repair blocks, which may be used by the receiver to reconstruct the missing packets and/or original packets of the block.
As introduced above, for each block, the transmitter maintains sufficient information to determine the highest index of a packet received at the receiver, the number of missing packets transmitted prior to that packet, and the number of original or redundancy packets after the highest index received that have been transmitted (i.e., are “in flight” unless erased in transit) or queued for transmission at the transmitter.
When the transmitter receives missing packet feedback for a block, if the number of packets for the block that are “in flight” or queue would not be sufficient if received successfully (or are not expected to be in view of the erasure rate), the transmitter computes (or retrieves precomputed) a new redundant packet for the block and queues it for transmission. Such redundancy packets are referred to as repair packets. In order to reduce the delay in reconstructing a block of packets at the receiver, the repair packets are sent preferentially to the information packets for later blocks. For instance, the repair packets are queued in a separate higher-priority queue that is used to ensure transmission of repair packets preferentially to the queue of information packets.
In some situations, feedback from the receiver may have indicated that a packet is missing. However, that packet may later arrive out of order, and therefore a redundant packet for that block that was earlier computed and queued for transmission is no longer required to be delivered to the receiver. If that redundant packet has not yet been transmitted (i.e., it is still queued), that packet may be removed from the queue thereby avoiding wasted use of channel capacity for a packet that will not serve to pass new information to the receiver.
In the approach described above, redundancy packets are sent as repair packets in response to feedback from the receiver. In some examples, some redundancy packets are sent pre-emptively (i.e., as forward error correction) in order to address possible packet erasures. One approach to send such forward error correction packets for each block. However, if feedback has already been received at the transmitter that a sufficient number of original and/or coded packets for a block have been received, then there is no need to send further redundant packets for the block.
In an implementation of this approach, the original packets for all the blocks of the batch are sent first, while repair packets are being preferentially sent based on feedback from the receiver. After all the original packets have been transmitted, and the queue of repair packets is empty, the transmitter computes (or retrieves precomputed) redundancy packets for blocks for which the transmitter has not yet received feedback that the blocks have been successfully received, and queues those blocks as forward error correction packets for transmission in the first queue. In general, because the repair blocks are sent with higher priority that the original packets, the blocks for which success feedback has not yet been received are the later blocks in the batch (e.g., a trailing sequence of blocks of the batch).
In various versions of this approach, the number and order of transmission of the forward error correction packets are determined in various ways. A first way uses the erasure rate to determine how many redundant packets to transmit. One approach is to send at least one redundant packet for each outstanding block. Another approach is to send a number of redundancy packets for each outstanding block so that based on an expectation of the erasure rate of the packets that are queued and in flight for the block will yield a sufficient number of successfully received packets in order to reconstruct the block. For example, if a further n packets are needed to reconstruct a block (e.g., a number n<N packets of the original N packets with N−n packets having been erased), then n+k packets are sent, for instance, with n+k≥n/E, where E is an estimate of the erasure rate on the channel.
Another way of determining the number and order of forward error correction packets addresses the situation in which a block transmission time is substantially less than the round-trip-time for the channel. Therefore, the earliest of the blocks for which the transmitter has not received success feedback may in fact have the success feedback in flight from the receiver to the transmitter, and therefore sending forward error correction packets may be wasteful. Similarly, even if feedback indicating missing packet feedback for a block is received sufficiently early, the transmitter may still send a repair packet without incurring more delay in complete reconstruction of the entire batch than would be achieved by forward error correction.
In an example, the number of forward error correction packets queued for each block is greater for later blocks in the batch than for earlier ones. A motivation for this can be understood by considering the last block of the batch where it should be evident that it is desirable to send a sufficient number of forward error correction packets to ensure high probability of the receiver having sufficient information to reconstruct the block without the need from transmission of a repair packet and the associated increase in latency. On the other hand, it is preferable to send fewer forward error correction packets for the previous (or earlier) block because in the face of missing packet feedback from the receiver, the transmitter may be able to send a repair packet before forward error correction packets for all the later blocks have been sent, thereby not incurring a delay in overall delivery of the batch.
In one implementation, after all the original packets have been sent, and the transmitter is in the forward error correction phase in which it computes and sends the forward error correction packets, if the transmitter receives a missing packet feedback from the receiver, it computes and sends a repair packet for the block in question (if necessary) as described above, and clears the entire queue of forward error correction packets. After the repair packet queue is again empty, the transmitter again computes and queues forward error correction packets for the blocks for which it has not yet received success feedback. In an alternative somewhat equivalent implementation, rather than clearing the forward error correction queue upon receipt of a missing packet feedback, the transmitter removes forward error correction packets from the queue as they are no longer needed based on feedback from the receiver. In some examples, if success feedback is received for a block for which there are queued forward error correction packets, those forward error correction packets are removed from the queue. In some examples, the feedback from the receiver may indicate that some but not all of the forward error correction packets in the queue are no longer needed, for example, because out-of-order packets were received but at least some of the original packets are still missing.
An example of the way the transmitter determines how many forward error correction packets to send is that the transmitter performs a computation:
(N+g(i)−ai)/(1−p)−fi
where
p=smoothed loss rate,
N=block size,
i=block index defined as number of blocks from last block,
ai=number of packets acked from block i,
fi=packets in-flight from block i, and
g(i)=a decreasing function of i,
to determine the number of FEC packets for a block.
In some examples, g (i) is determined as a maximum of a configurable parameter, m and N−i. In some examples, g(i) is determined as N−p(i) where p is a polynomial, with integer rounding as needed
It should be understood that in some alternative implementations, at least some forward error correction packets may be interspersed with the original packets. For example, if the erasure rate for the channel is relatively high, then at least some number of redundancy packets may be needed with relatively high probability for each block, and there is an overall advantage to preemptively sending redundant FEC packets as soon as possible, in addition to providing the mechanism for feedback based repair that is described above.
It should be also understood that use of subdivision of a batch into blocks is not necessarily required in order to achieve the goal of minimizing the time to complete reconstruction of the block at the receiver. However, if the forward error correction is applied uniformly to all the packets of the batch, then the preferential protection of later packets would be absent, and therefore, latency caused by erasure of later packets may be greater than using the approach described above. However, alternative approaches to non-uniform forward error protection (i.e., introduction of forward error correction redundancy packets) may be used. For example, in the block based approach described above, packets of the later blocks each contribute to a greater number of forward error correction packets than do earlier ones, and an alternative approach to achieving this characteristic maybe to use a non-block based criterion to construction of the redundancy packets in the forward error correction phase. However, the block based approach described above has advantages of relative simplicity and general robustness, and therefore even if marginally “suboptimal” provides an overall advantageous technical solution to minimizing the time to complete reconstruction within the constraint of throughput and erasure on the channel linking the transmitter and receiver.
Another advantage of using a block-based approach is that, for example, when a block within the batch, say the mth block of M blocks of the batch has an erasure, the repair packet that is sent from the transmitter depends only on the N original packets of the mth block. Therefore, as soon as the repair packet arrives, and the available (i.e., not erased) N−1 packets of the block arrive, the receiver has the information necessary to repair the block. Therefore, by constructing the repair packet without contribution of packets in later blocks of the batch, the latency of the reconstruction of the block is reduced. Furthermore, by having the repair packets depend on only N original packets, the computation required to reconstruct the packets of the block is less than if the repair packets depend on more packets.
It should be understood that even in the block based transmission of a batch of packets, the blocks are not necessarily uniform in size, and are not necessarily disjoint. For example, blocks may overlap (e.g., by 50%, 75%, etc.) thereby maintaining at least some of the advantages of reduced complexity in reconstruction and reduced buffering requirements as compared to treating the batch as one block. An advantage of such overlapping blocks may be a reduced latency in reconstruction because repair packets may be sent that do not require waiting for original packets at the receiver prior to reconstruction. Furthermore, non-uniform blocks may be beneficial, for example, to increase the effectiveness of forward error correction for later block in a batch by using longer blocks near the end of a batch as compared to near the beginning of a batch.
In applications in which the entire batch is needed by the destination application before use, low latency of reconstruction may be desirable to reduce buffering requirements in the PC-TCP module at the receiver (and at the transmitter). For example, all packets that may contribute to a later received repair packet are buffered for their potential future use. In the block based approach, once a block is fully reconstructed, then the PC-TCP module can deliver and discard those packets because they will not affect future packet reconstruction.
Although described as an approach to delivery of a batch of packets, the formation of these batches may be internal to the PC-TCP modules, whether or not such batches are formed at the software application level. For example, the PC-TCP module at the transmitter may receive the original data units that are used to form the original packets via a software interface from the source application. The packets are segmented into blocks of N packets as described above, and the packets queued for transmission. In one embodiment, as long as the source application provides data units sufficiently quickly to keep the queue from emptying (or from emptying for a threshold amount of time), the PC-TCP module stays in the first mode (i.e., prior to sending forward error correction packets) sending repair packets as needed based on feedback information from the receiver. When there is a lull in the source application providing data units, then the PC-TCP module declares that a batch has been completed, and enters the forward error correction phase described above. In some examples, the batch formed by the PC-TCP module may in fact correspond to a batch of data units generated by the source application as a result of a lull in the source application providing data units to the PC-TCP module while it computes data units for a next batch, thereby inherently synchronizing the batch processing by the source application and the PC-TCP modules.
In one such embodiment, the PC-TCP module remains in the forward error correction mode for the declared batch until that entire batch has been successfully reconstructed at the receiver. In another embodiment, if the source application begins providing new data units before the receiver has provided feedback that the previous batch has been successfully reconstructed, the transmitter PC-TCP module begins sending original packets for the next batch at a lower priority than repair or forward error correction packets for the previous batch. Such an embodiment may reduce the time to the beginning of transmission of the next batch, and therefore reduces the time to successful delivery of the next batch.
In the embodiments in which the source application does not necessarily provide the data in explicit batches, the receiver PC-TCP module provides the data units in order to the destination application without necessarily identifying the block or batch boundaries introduced at the transmitter PC-TCP module. That is, in at least some implementations, the transmitter and receiver PC-TCP modules provide a reliable channel for the application data units without exposing the block and batch structure to the applications.
As described above for certain embodiments, the transmitter PC-TCP module reacts to missing packet feedback from the receiver PC-TCP module to send repair packets. Therefore, it should be evident that the mechanism by which the receiver sends such feedback may affect the overall behavior of the protocol. For example, in one example, the receiver PC-TCP module sends a negative acknowledgment as soon as it observes a missing packet. Such an approach may provide the lowest latency for reconstruction of the block. However, as introduced above, missing packets may be the result of out-of-order delivery. Therefore, a less aggressive generation of missing packet feedback, for example, by delay in transmission of a negative acknowledgment, may reduce the transmission of unnecessary repair packets with only a minimal increase in latency in reconstruction of that block. However, such delay in sending negative acknowledgements may have an overall positive impact on the time to successfully reconstruct the entire block because later blocks are not delayed by unnecessary repair packets. Alternative approaches to generation of acknowledgments are described below.
In some embodiments, at least some of the determination of when to send repair packets is performed at the transmitter PC-TCP. For example, the receiver PC-TCP module may not delay the transmission of missing packet feedback, and it is the transmitter PC-TCP module that delays the transmission of a repair packet based on its weighing of the possibility of the missing packet feedback being based on out-of-order delivery as opposed to erasure.
Protocol Parameters
Communication between two PC-TCP endpoints operates according to parameters, some of which are maintained in common by the endpoints, and some of which are local to the sending and/or the receiving endpoint. Some of these parameters relate primarily to forward error correction aspects of the operation. For example, such parameters include the degree of redundancy that is introduced through the coding process. As discussed below, further parameters related to such coding relate to the selection of packets for use in the combinations. A simple example of such selection is segmentation of the sequence of input data units into “frames” that are then independently encoded. In addition to the number of such packets for combination (e.g., frame length), other parameters may relate to overlapping and/or interleaving of such frames of data units and/or linear combinations of such data units.
Further parameters relate generally to transport layer characteristics of the communication approach. For example, some parameters relate to congestion avoidance, for example, representing a size of a window of unacknowledged packets, transmission rate, or other characteristics related to the timing or number of packets sent from the sender to the receiver of the PC-TCP communication.
As discussed further below, communication parameters (e.g., coding parameters, transport parameters) may be set in various ways. For example, parameters may be initialized upon establishing a session between two PC-TCP endpoints. Strategies for setting those parameters may be based on various sources of information, for example, according to knowledge of the communication path linking the sender and receiver (e.g., according to a classification of path type, such as 3G wireless versus cable modem), or experienced communication characteristics in other sessions (e.g., concurrent or prior sessions involving the same sender, receiver, communication links, intermediate nodes, etc.). Communication parameters may be adapted during the course of a communication session, for example, in response to observed communication characteristics (e.g., congestion, packet loss, round-trip time, etc.)
Some aspects of the PC-TCP approaches relate to control of transmission of packets from a sender to a receiver. These aspects are generally separate from aspects of the approach that determine what is sent in the packets, for example, to accomplish forward error correction, retransmission, or the order in which the packets are sent (e.g., relative priority of forward error correction packets version retransmission packets). Given a queue of packets that are ready for transmission from the sender to the receiver, these transmission aspects generally relate to flow and/or congestion control.
Current variants of TCP, including binary increase congestion control (BIC) and cubic-TCP, have been proposed to address the inefficiencies of classical TCP in networks with high losses, large bandwidths and long round-trip times. BIC-TCP and CUBIC algorithms have been used because of their stability. After a backoff, BIC increases the congestion window linearly then logarithmically to the window size just before backoff (denoted by Wmax) and subsequently increases the window in an anti-symmetric fashion exponentially then linearly. CUBIC increases the congestion window following backoff according to a cubic function with inflection point at Wmax. These increase functions cause the congestion window to grow slowly when it is close to promoting stability. On the other hand, other variants such as HTCP and FAST TCP have the advantage of being able to partially distinguish congestion and non-congestion losses through the use of delay as a congestion signal.
An alternative congestion control approach is used in at least some embodiments. In some such embodiments, we identify a concave portion of the window increase function as Wconcave(t)=Wmax+c1(t−k)3 and a convex portion of the window increase function as Wconvex (t)=Wmax+c2(t−k) where c1 and c2 are positive tunable parameters and
and W is the window size just after backoff.
This alternative congestion control approach can be flexibly tuned for different scenarios. For example, a larger value of c1 causes the congestion window to increase more rapidly up to Wmax and a large value of c2 causes the congestion window to increase more rapidly beyond Wmax.
Optionally, delay is used as an indicator to exit slow start and move to the more conservative congestion avoidance phase, e.g. when a smoothed estimate of RTT exceeds a configured threshold relative to the minimum observed RTT for the connection. We can also optionally combine the increase function of CUBIC or other TCP variants with the delay-based backoff function of HTCP.
In some embodiments, backoff is smoothed by allowing a lower rate of transmission until the number of packets in flight decreases to the new window size. For instance, a threshold, n, is set such that once n packets have been acknowledged following a backoff, then one packet is allowed to be sent for every two acknowledged packets, which is roughly half of the previous sending rate. This is akin to a hybrid window and rate control scheme.
In at least some embodiments, pacing is used to regulate and/or spread out packet transmissions, making the transmission rate less bursty. While pacing can help to reduce packet loss from buffer overflows, previous implementations of pacing algorithms have not shown clear advantages when comparing paced TCP implementations to non-paced TCP implementations. However, in embodiments where the data packets are coded packets as described above, the combination of packet coding and pacing may have advantages. For example, since one coded packet may be used to recover multiple possible lost packets, we can use coding to more efficiently recover from any spread out packet losses that may result from pacing. In embodiments, the combination of packet coding and pacing may have advantages compared to uncoded TCP with selective acknowledgements (SACK).
Classical TCP implements end-to-end congestion control based on acknowledgments. Variants of TCP designed for high-bandwidth connections increase the congestion window (and consequently the sending rate) quickly to probe for available bandwidth but this can result in bursts of packet losses when it overshoots, if there is insufficient buffering in the network.
A number of variants of TCP use acknowledgment feedback to determine round-trip time and/or estimate available bandwidth, and they differ in the mechanisms with which this information is used to control the congestion window and/or sending rate. Different variants have scenarios in which they work better or worse than others.
In one general approach used in one or more embodiments, a communication protocol may use smoothed statistics of intervals between acknowledgments of transmitted packets (e.g., a smoothed “ack interval”) to guide a transmission of packets, for example, by controlling intervals (e.g., an average interval or equivalently an average transmission rate) between packet transmissions. Broadly, this guiding of transmission intervals is referred to herein as “pacing”.
In some examples, the pacing approach is used in conjunction with a window-based congestion control algorithm. Generally, the congestion window controls the number of unacknowledged packets that can be sent, in some examples using window control approaches that are the same or similar to those used in known variants of the Transmission Control Protocol (TCP). In embodiments, the window control approach is based on the novel congestion control algorithms described herein.
A general advantage of one or more aspects is to improve functioning of a communication system, for instance, as measured by total throughput, or delay and/or variation in delay. These aspects address a technical problem of congestion, and with it packet loss, in a network by using “pacing” to reduce that congestion.
An advantage of this aspect is that the separate control of pacing can prevent packets in the congestion window from being transmitted too rapidly compared to the rate at which they are getting through to the other side. Without separate pacing control, at least some conventional TCP approaches would permit bursts of overly rapid transmission of packets, which might result in packet loss at an intermediate node on the communication path. These packet losses may be effectively interpreted by the protocol as resulting from congestion, resulting in the protocol reducing the window size. However, the window size may be appropriate, for example, for the available bandwidth and delay of the path, and therefore reducing the window size may not be necessary. On the other hand, reducing the peak transmission rate can have the effect of avoiding packet loss, for example, by avoiding overflow of intermediate buffers on the path.
Another advantage of at least some implementations is prevention of large bursts of packet losses under convex window increase functions for high-bandwidth scenarios, by providing an additional finer level of control over the transmission process.
At least some implementations of the approach can leverage the advantages of existing high-bandwidth variants of TCP such as H-TCP and CUBIC, while preventing large bursts of packet losses under their convex window increase functions and providing a more precise level of control. For example, pacing control may be implemented to pace the rate of providing packets from the existing TCP procedure to the channel, with the existing TCP procedure typically further or separately limiting the presentation of packets to the communication channel based, for instance, on its window-based congestion control procedure.
In practice, a particular example in which separating pacing from window control has been observed to significantly outperform conventional TCP on 4G LTE.

In
Functionally, one may consider two elements of the protocol as being loss recovery and rate/congestion control. Loss recovery can be implemented either using conventional retransmissions or using coding or as a combination of retransmission and coding. Rate/congestion control may aim to avoid overrunning the receiver and/or the available channel capacity, and may be implemented using window control with or without pacing, or direct rate control.
The channel 1050 coupling the transport layers in general may include lower layer protocol software at the source and destination, and a series of communication links coupling computers and other network nodes on a path from the source to the destination.
As compared to conventional approaches, as shown in
In embodiments, the acks that are transmitted on a return channel, from the destination to the source, may also be paced, and may also utilize coding to recover from erasures and bursty losses. In embodiments, packet coding and transmission control of the acks may be especially useful if there is congestion on the return channel.
In one implementation, the rate control element 1040 may maintain an average (i.e., smoothed) inter-packet delivery interval, estimated based on the acknowledgement intervals (accounting for the number of packets acknowledged in each ack). In some implementations this averaging may be computed as a decaying average of past sample inter-arrival times. This can be refined by incorporating logic for discarding large sample values based on the determination of whether they are likely to have resulted from a gap in the sending times or losses in the packet stream, and by setting configurable upper and lower limits on the estimated interval commensurate with particular characteristics of different known networks. The rate control element 1040 may then use this smoothed inter-acknowledgement time to set a minimum inter-transmission time, for example, as a fraction of the inter-acknowledgement time. This fraction can be increased with packet loss and with rate of increase of RTT (which may be indicators that the current sending rate may be too high), and decreased with rate of decrease of RTT under low loss, e.g. using a control algorithm such as proportional control whose parameters can be adjusted to trade off between stability and responsiveness to change. Upper and lower limits on this fraction can be made configurable parameters, say 0.2 and 0.95. Transmission packets are then limited to be presented to the channel 1050 with inter-transmission times of at least this set minimum. In other implementations inter-transmission intervals are controlled to maintain a smoothed average interval or rate based on a smoothed inter-acknowledgement interval or rate.
In addition to the short timescale adjustments of the pacing interval with estimated delivery interval, packet loss rate and RTT described above, there can also be a longer timescale control loop that modulates the overall aggressiveness of the pacing algorithm based on a smoothed loss rate calculated over a longer timescale, with, a higher loss rate indicating that pacing may be too aggressive. The longer timescale adjustment can be applied across short duration connections by having the client maintain state across successive connections and include initializing information in subsequent connection requests. This longer timescale control may be useful for improving adaptation to diverse network scenarios that change dynamically on different timescales.
Referring to
It should be recognized that although the description above focuses on a single direction of communication, in general, a bidirectional implementation would include a corresponding path from the destination application to the source application. In some implementations, both directions include corresponding rate control elements 1040, while in other applications, only one direction (e.g., from the source to the destination application) may implement the rate control. For example, introduction of the rate control element 1040 at a server, or another device or network node on the path between the source application and the transport layer 1080 at the destination, may not require modification of the software at the destination.
As described above, the sender can use acks to estimate the rate/interval with which packets are reaching the receiver, the loss rate and the rate of change of RTT, and adjust the pacing interval accordingly. However, this estimated information may be noisy if acks are lost or delayed. On the other hand, such information can be estimated more accurately at the receiver with OWTT in place of RTT. By basing the pacing interval on the rate of change of OWTT rather than its actual value, the need for synchronized clocks on sender and receiver may be obviated. The pacing interval can be fed back to the sender by including it as an additional field in the acks. The choice as to whether the pacing calculations are done at the sender or the receiver, or done every n packets rather than upon every packet reception, may also be affected by considerations of sender/receiver CPU/load.
Classical TCP performs poorly on networks with packet losses. Congestion control can be combined with coding such that coded packets are sent both for forward error correction (FEC) to provide protection against an anticipated level of packet loss, as well as for recovering from actual losses indicated by feedback from the receiver.
While the simple combination of packet coding and congestion control has been suggested previously, the prior art does not adequately account for differences between congestion-related losses, bursty and/or random packet losses. Since congestion-related loss may occur as relatively infrequent bursts, it may be inefficient to protect against this type of loss using FEC.
In at least some embodiments, the rates at which loss events occur are estimated. A loss event may be defined as either an isolated packet loss or a burst of consecutive packet losses. In some examples, the source PC-TCP may send FEC packets at the estimated rate of loss events, rather than the estimated rate of packet loss. This embodiment is an efficient way to reduce non-useful FEC packets, since it may not be disproportionately affected by congestion-related loss.
In an exemplary embodiment, the code rate and/or packet transmission rate of FEC can be made tunable in order to trade-off between the useful throughput seen at the application layer (also referred to as goodput) and recovery delay. For instance, the ratio of the FEC rate to the estimated rate of loss events can be made a tunable parameter that is set with a priori knowledge of the underlying communications paths or dynamically adjusted by making certain measurements of the underlying communications paths.
In another exemplary embodiment, the rate at which loss bursts of up to a certain length occur may be estimated, and appropriate burst error correcting codes for FEC, or codes that correct combinations of burst and isolated errors, may be used.
In another exemplary embodiment, the FEC for different blocks can be interleaved to be more effective against bursty loss.
In other exemplary embodiments, data packets can be sent preferentially over FEC packets. For instance, FEC packets can be sent at a configured rate or estimated loss rate when there are no data packets to be sent, and either not sent or sent at a reduced rate when there are data packets to be sent. In one implementation, FEC packets are placed in a separate queue which is cleared when there are data packets to be sent.
In other exemplary embodiments, the code rate/amount of FEC in each block and/or the FEC packet transmission rate can be made a tunable function of the block number and/or the number of packets in flight relative to the number of unacknowledged degrees of freedom of the block, in addition to the estimated loss rate. FEC packets for later blocks can be sent preferentially over FEC for earlier blocks, so as to minimize recovery delay at the end of a connection, e.g., the number of FEC packets sent from each block can be a tunable function of the number of blocks from the latest block that has not been fully acknowledged. The sending interval between FEC packets can be an increasing function of the number of packets in flight relative to the number of unacknowledged degrees of freedom of the corresponding block, so as to trade-off between sending delay and probability of losing FEC packets in scenarios where packet loss probability increases with transmission rate.
In other exemplary embodiments, a variable randomly chosen fraction of the coding coefficients of a coded packet can be set to 1 or 0 in order to reduce encoding complexity without substantially affecting erasure correction performance. In a systematic code, introducing 0 coefficients only after one or more densely coded packets (i.e. no or few 0 coefficients) may be important for erasure correction performance. For instance, an initial FEC packet in a block could have each coefficient set to 1 with probability 0.5 and to a uniformly random value from the coding field with probability 0.5. Subsequent FEC packets in the block could have each coefficient set to 0 with probability 0.5 and to uniformly random value with probability 0.5.
As introduced above, packets may be received out of order on some networks, for example, due to packets traversing multiple paths, parallel processing in some networking equipment, reconfiguration of a path (e.g., handoff in cellular networks). Generally, conventional TCP reacts to out of order packets by backing off the size of the congestion window. Such a backoff may unnecessarily hurt performance if there is no congestion necessitating a backoff.
In some embodiments, in an approach to handling packet reordering that does not result from congestions, a receiver observing a gap in the sequence numbers of its received packets may delay sending an acknowledgment for a limited time. When a packet is missing, the receiver does not immediately know if the packet has been lost (erased), or merely reordered. The receiver delays sending an acknowledgement that indicates the gap to see if the gap is filled by subsequent packet arrivals. In some examples, upon observing a gap, the receiver starts a first timer for a configurable “reordering detection” time interval, e.g. 20 ms. If a packet from the gap is subsequently received within this time interval, the receiver starts a second timer for a configurable “gap filling” time interval, e.g. 30 ms. If the first timer or the second timer expire prior to the gap being filled, an acknowledgement that indicates the gap is sent to the source.
Upon receiving the acknowledgment that indicates the gap in received packets the source, in at least some embodiments, the sender determines whether a repair packet should be sent to compensate for the gap in the received packets, for example, if a sufficient number of FEC packets have not already been sent.
In another aspect, a sender may store relevant congestion control state information (including the congestion window) prior to backoff, and a record of recent packet losses. If the sender receives an ack reporting a gap/loss and then subsequently one or more other acks reporting that the gap has been filled by out of order packet receptions, any backoff caused by the earlier ack can be reverted by restoring the stored state from before backoff.
In another aspect, a sender observing a gap in the sequence numbers of its received acks may delay congestion window backoff for a limited time. When an ack is missing, the sender does not immediately know if a packet has been lost or if the ack is merely reordered. The sender delays backing off its congestion window to see if the gap is filled by subsequent ack arrivals. In some examples, upon observing a gap, the sender starts a first timer for a configurable “reordering detection” time interval, e.g. 20 ms. If an ack from the gap is subsequently received within this time interval, the sender starts a second timer for a configurable “gap filling” time interval, e.g. 30 ms. If the first timer or the second timer expires prior to the gap being filled, congestion window backoff occurs.
In some examples, instead of using time intervals, packet sequence numbers are used. For example, sending of an ack can be delayed until a packet which is a specified number of sequence numbers ahead of the reference lost packet is received. Similarly, backing off can be delayed until an acknowledgment of a packet which is a specified number of sequence numbers ahead of the reference lost packet is received. In some examples, these approaches have the advantage of being able to take into account subsequently received/acknowledged reordered packets by shifting the sequence number of the reference lost packet as holes in the packet sequence get filled.
These methods for correcting packet reordering may be especially useful for multipath versions of the protocol, where there may be a large amount of reordering.
In at least some implementations, conventional TCP sends one acknowledgment for every two data packets received. Such delayed acking reduces ack traffic compared to sending an acknowledgment for every data packet. This reduction in ack traffic is particularly beneficial when there is contention on the return channel, such as in Wi-Fi networks, where both data and ack transmissions contend for the same channel.
It is possible to reduce ack traffic further by increasing the ack interval to a value n>2, i.e. sending one acknowledgment for every n data packets. However, reducing the frequency with which acks are received by the sender can cause delays in transmission (when the congestion window is full) or backoff (if feedback on losses is delayed), which can hurt performance.
In one aspect, the sender can determine whether, or to what extent, delayed acking should be allowed based in part on its remaining congestion window (i.e. its congestion window minus the number of unacknowledged packets in flight), and/or its remaining data to be sent. For example, delayed acking can be disallowed if there is any packet loss, or if the remaining congestion window is below some (possibly tunable) threshold. Alternatively, the ack interval can be reduced with the remaining congestion window. As another example, delayed acking can be allowed if the amount of remaining data to be sent is smaller than the remaining congestion window, but disallowed for the last remaining data packet so that there is no delay in acknowledging the last data packet. This information can be sent in the data packets as a flag indicating whether delayed acking is allowed, or for example, as an integer indicating the allowed ack interval.
Using relevant state information at the sender to influence delayed acking may allow an increase in the ack interval beyond the conventional value of 2, while mitigating the drawbacks described above that a larger ack interval across the board might have.
To additionally limit the ack delay, each time an ack is sent, a delayed ack timer can be set to expire with a configured delay, say 25 ms. Upon expiration of the timer, any data packets received since the last ack may be acknowledged, even if fewer packets than the ack interval n have arrived. If no packets have been received since the last ack, an ack may be sent upon receipt of the next data packet.
In some embodiments, to establish a session parameters for the PC-TCP modules are set to a predefine set of default parameters. In other embodiments, approaches that attempt to select better initial parameters are used. Approaches include use of parameter values from other concurrent or prior PC-TCP sessions, parameters determined from characteristics of the communication channel, for example, selected from stored parameters associated with different types of channels, or parameters determined by the source or destination application according to the nature of the data to be transported (e.g., batch versus stream).

The channel 2452 may be treated as carrying a series of data units, which may but do not necessarily correspond directly to Internet Protocol (IP) packets. For example, in some implementations multiple data units are concatenated into an IP packet, while in other implementations, each data unit uses a separate IP packet or only part of an IP packet. It should be understood that in yet other implementations, the Internet Protocol is not used—the techniques described below do not depend on the method of passing the data units over the channel 2452.
A transmitter 2421 couples the server application 2411 to the channel 2452, and a receiver 2481 couples the channel 2452 to the client application 2491. Generally, the transmitter 2421 accepts input data units from the server application 2481. In general, these data units are passed over the channel 2452, as well as retained for a period of time in a buffer 2423. From time to time, an error control (EC) component 2425 may compute a redundancy data unit from a subset of the retained input data units in the buffer 2423, and may pass that redundancy data unit over the channel 2452. The receiver 2481 accepts data units from the channel 2452. In general, the channel 2452 may erase and reorder the data units. Erasures may correspond to “dropped” data units that are never received at the receiver, as well as corrupted data units that are received, but are known to have irrecoverable errors, and therefore are treated for the most part as dropped units. The receiver may retain a history of received input data units and redundancy data units in a buffer 2483. An error control component 2485 at the receiver 2481 may use the received redundancy data units to reconstruct erased input data units that may be missing in the sequence received over the channel. The receiver 2481 may pass the received and reconstructed input data units to the client application. In general, the receiver may pass these input data units to the client application in the order they were received at the transmitter.
In general, if the channel has no erasures or reordering, the receiver can provide the input data units to the client application with delay and delay variation that may result from traversal characteristics of the channel. When data units are erased in the channel 2452, the receiver 2481 may make use of the redundancy units in its buffer 2483 to reconstruct the erased units. In order to do so, the receiver may have to wait for the arrival of the redundancy units that may be useful for the reconstruction. The way the transmitter computes and introduces the redundancy data units generally affects the delay that may be introduced to perform the reconstruction.
The way the transmitter computes and introduces the redundancy data units as part of its forward error correction function can also affect the complexity of the reconstruction process at the receiver, and the utilization of the channel. Furthermore, regardless of the nature of the way the transmitter introduces the redundancy data units onto the channel, statistically there may be erased data units for which there is insufficient information in the redundancy data units to reconstruct the erased unit. In such cases, the error control component 2485 may request a retransmission of information from the error control component 2425 of the transmitter 2421. In general, this retransmitted information may take the form of further redundancy information that depends on the erased unit. This retransmission process introduces a delay before the erased unit is available to the receiver. Therefore, the way the transmitter introduces the redundancy information also affects the statistics such as how often retransmission of information needs to be requested, and with it the delay in reconstructing the erased unit that cannot be reconstructed using the normally introduced redundancy information.
In some embodiments, the error control component 2485 may provide information to the error control component 2425 to affect the way the transmitter introduces the redundancy information. In general, this information may be based on one or more of the rate of (or more generally the pattern of) erasures on units on the channel, rate of (or more generally timing pattern of) and the state of the available units in the buffer 2483 and/or the state of unused data in the client application 2491. For example, the client application may provide a “play-out time” (e.g., in milliseconds) of the data units that the receiver has already provided to the client application such that if the receiver were to not send any more units, the client application would be “starved” for input units at that time. Note that in other embodiments, rather than or in addition to receiving information from the receiver, the error control component 2425 at the transmitter may get feedback from other places, for example, from instrumented nodes in the network that pass back congestion information.
Referring to
In a number of embodiments the redundancy units are computed as random linear combinations of past input units. Although the description below focuses on such approaches, it should be understood that the overall approach is applicable to other computations of redundancy information, for example, using low density parity check (LDPC) codes and other error correction codes. In the approach shown in
In
For a particular rate of code (e.g., rate R=⅔), in an example, feedback received may result in changes of the parameters, for example, between (p,q)=(2,1) or (4,2) or (8,4) depending on of the amount of data buffered at the receiver, and therefore depending on the tolerance of the receiver to reconstruction delay.
Note that it is not required that q=p(1−R)/R is an integer, as it is in the examples shown in
In a variant of the approach described above, different input data units have different “priorities” or “importances” such that they are protected to different degrees than other input data units. For example, in video coding, data units representing an independently coded video frame may be more important than data units representing a differentially encoded video frame. For example, if the priority levels are indexed i=1, 2, . . . , then a proportion ρi≤1, where Σiρi=1, of the redundancy data units may be computed using data units with priority 1. For example, for a rate R code, with blocks of input data units of length p, on average ρi p(1−R)/R redundancy data units per block are computed from input data units with priority.
The value of D should generally be no more than the target playout delay of the streaming application minus an appropriate margin for communication delay variability. The playout delay is the delay between the time a message packet is transmitted and the time it should be available at the receiver to produce the streaming application output. It can be expressed in units of time, or in terms of the number of packets transmitted in that interval. D can be initially set based on the typical or desired playout delay of the streaming application, and adapted with additional information from the receiver/application. Furthermore, choosing a smaller value reduces the memory and complexity at the expense of erasure correction capability.
The parameter d specifies the minimum separation between a message packet and a parity involving that message packet. Since a parity involving a message packet that has not yet been received is not useful for recovering earlier message packets involved in that parity, setting a minimum parity delay can improve decoding delay when packet reordering is expected/observed to occur, depending partly also on the parity interval.

In some embodiments, the control of transport layer sessions uses information across connections, for example, across concurrent sessions or across sessions occurring at different times.
Standard TCP implements end-to-end congestion control based on acknowledgments. A new TCP connection that has started up but not yet received any acknowledgments uses initial configurable values for the congestion window and retransmission timeout. These values may be tuned for different types of network settings.
Some applications, for instance web browser applications, may use multiple connections between a client application (e.g., the browser) and a server application (e.g., a particular web server application at a particular server computer). Conventionally, when accessing the information to render a single web “page”, the client application may make many separate TCP sessions between the client and server computers, and using conventional TCP control, each session is controlled substantially independently. This independent control includes separate congestion control.
One approach to addressing technical problems that are introduced by having such multiple sessions is the SPDY Protocol (see, e.g., SPDY Protocol—Draft 3.1, accessible at http://www.chromium.org/spdy/spdy-protocol/spdy-protocol-draft3-1). The SPDY protocol is an application layer protocol that manipulates HTTP traffic, with particular goals of reducing web page load latency and improving web security. Generally, SPDY effectively provides a tunnel for the HTTP and HTTPS protocols. When sent over SPDY, HTTP requests are processed, tokenized, simplified and compressed. The resulting traffic is then sent over a single TCP session, thereby avoiding problems and inefficiencies involved in use of multiple concurrent TCP sessions between a particular client and server computer.
In a general aspect, a communication system maintains information related to communication between computers or network nodes. For example, the maintained information can include bandwidth to and/or from the other computer, current or past congestion window sizes, pacing intervals, packet loss rates, round-trip time, timing variability, etc. The information can include information for currently active sessions and/or information about past sessions. One use of the maintained information may be to initialize protocol parameters for a new session between computers for which information has been maintained. For example, the congestion window size or a pacing rate for a new TCP or UDP session may be initialized based on the congestion window size, pacing interval, round-trip time and loss rate of other concurrent or past sessions.

In one use scenario, when a client 1290 seeks to establish a communication session (e.g., a transport layer protocol session), it consults its communication information 1295 to see if it has current information that is relevant to the session it seeks to establish. For example, the client may have other concurrent sessions with a server with which it wants to communicate, or with which it may have recently had such sessions. As another example, the client 1290 may use information about other concurrent or past sessions with other servers. When the client 1290 sends a request to a server 1210 or a proxy 1212 to establish a session, relevant information for that session is also made available to one or both of the endpoints establishing the session. There are various ways in which the information may be made available to the server. For example the information may be included with the request itself. As another example, the server may request the information if it does not already hold the information in its communication information 1215. As another example, the server may request the information from a remote or third party database, which has been populated with information from the client or from servers that have communicated with the client. In any case, the communication session between the client and the server is established using parameters that are determined at least in part by the communication information available at the client and/or server.
In some examples, the communication session may be established using initial values of packet pacing interval, congestion window, retransmission timeout and forward error correction. Initial values suitable for different types of networks (e.g. Wi-Fi, 4G), network operators and signal strength can be prespecified, and/or initial values for successive connections can be derived from measured statistics of earlier connections between the same endpoints in the same direction. For example:
The initial congestion window can be increased from its default value if the packet throughput of the previous connection is sufficiently larger than the ratio of the default initial congestion window to the minimum round-trip time of the previous connection. The congestion window can subsequently be adjusted downwards if the initial received acks from the new connection indicate that the available rate has decreased compared to the previous connection.
The initial pacing interval can be set e.g. as MAX(k1*congestion window/previous round-trip time, k2/previous packet throughput), where k1 and k2 are configurable parameters, or, with receiver pacing, as k*previous pacing interval, where k increases with the loss rate of the previous connection.
Forward error correction parameters such as code rate can be set as k*previous loss rate, where k is a configurable parameter. The initial retransmission timeout can be increased from its default value if the minimum round-trip time of the previous connection is larger.
For each path, the algorithms described above that embody transmission and congestion control, forward error correction, sender based pacing, receiver based pacing, stream based parameter tuning, detection and correction for missing and out of order packets, use of information across multiple TCP connections, fast connection start and stop, TCP/UDP fallback, cascaded coding, recoding by intermediate nodes, and coding of the ACKs can be employed to improve the overall end-to-end throughput over the multiple paths between the source node and destination node. When losses are detected and FEC is used, the extra coded packets can be sent over any or all of the paths. For instance, coded packets sent to repair losses can be sent preferentially over lower latency paths to reduce recovery delay. The destination node will decode any N of packets that are received over all of the paths and assemble them into a block of N original packets by recreating any missing packets from the ones received. If less than N different coded packets are received across all paths, then the destination node will request the number of missing packets x where x=N−number of packets received be retransmitted. Any set of x different coded packet can be retransmitted over any path and then used to reconstruct the missing packets in the block of N.
When there are networks with large differences in round trip time (RTT) latencies, the packets received over the lower RTT latencies will need to be buffered at the receiver in order to be combined with the higher RTT latency packets. The choice of packets sent on each path can be controlled so as to reduce the extent of reordering and associated buffering on the receiver side, e.g. among the packets available to be sent, earlier packets can be sent preferentially on higher latency paths and later packets can be sent preferentially on lower latency paths.
Individual congestion control loops may be employed on each path to adapt to the available bandwidth and congestion on the path. An additional overall congestion control loop may be employed to control the total sending window or rate across all the paths of a multi-path connection, for fairness with single-path connections.

In some examples, other types of messages may be preferentially sent over the low latency data path. For example, acknowledgement messages, retransmission messages, and/or other time critical messages may be transmitted over the low latency data path while other data messages are transmitted over the higher latency data path.
In some examples, additional data paths with different characteristics (e.g., latencies) can also be included in the communication system, with messages being balanced over any of a number of data paths based on characteristics of the messages (e.g., message type) and characteristics of the data paths.

In the document above, certain features of the packet coding and transmission control protocols are described individually, or in isolation, but it should be understood that there are certain advantages that may be gained by combining multiple features together. Preferred embodiments for the packet coding and transmission control protocols described may depend on whether the transmission links and network nodes traversed between communication session end-points belong to certain fiber or cellular carriers (e.g. AT&T, T-Mobile, Sprint, Verizon, Level 3) and/or end-user Internet Service Providers (ISPs) (e.g. AT&T, Verizon, Comcast, Time Warner, Century Link, Charter, Cox) or are over certain wired (e.g. DSL, cable, fiber-to-the-curb/home (FTTx)) or wireless (e.g. WiFi, cellular, satellite) links. In embodiments, probe transmissions may be used to characterize the types of network nodes and transmission links communication signals are traversing and the packet coding and transmission control protocol may be adjusted to achieve certain performance. In some embodiments, data transmissions may be monitored to characterize the types of network nodes and transmission links communication signals are traversing and the packet coding and transmission control protocol may be adjusted to achieve certain performance. In at least some embodiments, quantities such as round-trip-time (RTT), one-way transmission times (OWTT), congestion window, pacing rate, packet loss rate, number of overhead packets, and the like may be monitored continuously, intermittently, in response to a trigger signal or event, and the like. In at least some embodiments, combinations of probe transmissions and data transmissions may be used to characterize network and communication session performance in real time.
In at least some embodiments, network and communication parameters may be stored in the end-devices of communication sessions and/or they may be stored in network resources such as servers, switches, nodes, computers, databases and the like. These network and communication parameters may be used by the packet coding and transmission control protocol to determine initial parameter settings for the protocol to reduce the time it may take to adjust protocol parameters to achieve adequate performance. In embodiments, the network and communication parameters may be tagged and/or associated with certain geographical locations, network nodes, network paths, equipment types, carrier networks, service providers, types of transmission paths and the like. In embodiments, the end-devices may be configured to automatically record and/or report protocol parameter settings and to associate those settings with certain locations determined using GPS-type location identification capabilities resident in those devices. In embodiments, the end-devices may be configured to automatically record and/or report protocol parameters settings and to associate those settings with certain carrier networks, ISP equipment traversed, types of wired and/or wireless links and the like.
In at least some embodiments, a packet coding and transmission control protocol as described above may adjust more than one parameter to achieve adequate or improved network performance. Improved network performance may be characterized by less delay in delivering data packets, less delay in completing file transfers, higher quality audio and video signal delivery, more efficient use of network resources, less power consumed by the end-users, more end-users supported by existing hardware resources and the like.
In at least some embodiments, certain modules or features of the packet coding and transmission control protocol may be turned on or off depending on the data's path through a network. In some embodiments, the order in which certain features are implemented or controlled may be adjusted depending on the data's path through a network. In some embodiments, the probe transmissions and/or data transmissions may be used in open-loop or closed-loop control algorithms to adjust the adjustable parameters and/or the sequence of feature implementation in the packet coding and transmission control protocol.
It should be understood that examples which involve monitoring to control the protocol can in general involve aspects that are implemented at the source, the destination, or at a combination of the source and the destination Therefore, it should be evident that although embodiments are described above in which features are described as being implemented at particular endpoints, alternative embodiments involve implementation of those features at different endpoints. Also, as described above, monitoring to control the protocol can in general involve aspects that are implemented intermediate nodes or points in the network. Therefore, it should be evident that although embodiments are described above in which features are described as being implemented at particular endpoints, alternative embodiments involve implementation of those features at different nodes, including intermediate nodes, throughout the network.
In addition to the use of monitored parameters for control of the protocols, the data may be used for other purposes. For example, the data may support network analytics that are used, for example, to control or provision the network as a whole.
The PC-TCP approaches may be adapted to enhance existing protocols and procedures, and in particular protocols and procedures used in content delivery, for example, as used in coordinated content delivery networks. For instance, monitored parameters may be used to direct a client to the server or servers that can deliver an entire unit of content as soon as possible rather than merely direct the client to a least loaded server or to server accessible over a least congested path. A difference in such an new approach is that getting an entire file as fast as possible may require packets to be sent from multiple servers and/or servers that are not geographically the closest, over multiple links, and using new acknowledgement protocols that coordinate the incoming data while requiring a minimum of retransmissions or FEC overhead. Coordinating may include waiting for gaps in strings of packets (out-of-order packets) to be filled in by later arriving packets and/or by coded packets. In addition, the PC-TCP approaches may improve the performance of wireless, cellular, and satellite links, significantly improving the end-to-end network performance.
Some current systems use “adaptive bit rates” to try to preserve video transmission through dynamic and/or poorly performing links. In some instances, the PC-TCP approaches described above replace adaptive bit rate schemes and may be able to present a very high data rate to a user for a long period of time. In other instances, the PC-TCP approaches are used in conjunction with currently-available adaptive bit rate schemes to support higher data rates on average than could be supported by adaptive bit rate schemes alone. In some instances, the PC-TCP approaches may include integrated bit rate adjustments as part of its feature set and may use any and/or all of the previously identified adjustable parameters and/or monitored parameters to improve the performance of a combined PC-TCP and bit-rate adaptive solution.
Certain embodiments described following relate to heating, and more particularly to cooking and recipes, including by use of intelligent devices, and in a context of the IoT.
With the emergence of the IoT, opportunities exist for unlocking value surrounding a wide range of devices. To date, such opportunities have been limited for many users, particularly in rural areas of developing countries, by the absence of robust energy and communications infrastructure. The same problems with infrastructure also limit the ability of users to access more basic features of certain devices; for example, rather than using modern cooking systems, such as with gas burners, many rural users still cook over fires, using wood or other biofuel. A need exists for devices that meet basic needs, such as for modern cooking capability, without reliance on infrastructure, and an opportunity exists to expand the capabilities of basic cooking devices to provide a much wider range of capabilities that will serve other needs and provide other benefits to users of cooking devices.
Many industrial environments are similarly isolated from conventional energy and communications infrastructure. For example, offshore drilling platforms, industrial mining environments, pipeline operations, large-scale agricultural environments, marine exploration environments (e.g., deep ocean exploration), marine and other large-scale transportation environments (such as ships, boats, submarines, aircraft and spacecraft) are often entirely isolated from the traditional power grid, or require very expensive power transmission cables to receive power from traditional sources. Other industrial environments are isolated for other reasons, such as to maintain “clean room” isolation during semi-conductor manufacturing, pharmaceutical preparation, or handling of hazardous materials, where interfaces like outlets and switches for delivering conventional power potentially provide points of penetration or escape for contaminants or biologically active materials. For these environments, a need exists for cooking systems that provide improved independence from conventional power sources. Also, in many of these environments fire is a significant hazard, among other things because of the presence of fire hazards and significant restrictions on egress for personnel. In those cases, storage of fuel for cooking in an environment presents a risk, because the fuel can exacerbate the extent of a fire, potentially resulting in disastrous consequences. Accordingly, such platforms and environments, such as oil drilling platforms, may use diesel generators to power cooking and other systems, because diesel is perceived as presenting lower risk than propane, gasoline, or other fuel sources; however, diesel fuel also burns and remains a significant hazard A need exists for safer mechanisms for providing cooking capability in isolated industrial environments.
Intelligent cooking systems are disclosed herein, including an intelligent cooking system that is provided with processing, communications, and other information technology components, for remote monitoring and control and various value-added features and services, embodiments of which use an electrolyzer, optionally a solar-powered electrolyzer, to produce hydrogen as an on-demand fuel stream for a heating element, such as a burner, of the cooking system.

These may include systems and components used in assembly lines (such as for heating, drying, curing, or otherwise treating parts or materials at one stage of production, such as to treat coatings, polymers, or the like that are coated, dispersed, painted, or otherwise disposed on components), in semi-conductor manufacturing and preparation (such as for heating or curing layers of a semi-conductor process, including in robotic assembly processes), in tooling processes (such as for curing injection molds and other molds, tools, dies, or the like), in extrusion processes (such as for curing, heating or otherwise treating results of extrusion), and many others. These may also include systems and components used in various industrial environments for servicing personnel, such as on ships, submarines, offshore drilling platforms, and other marine platforms, on large equipment, such as on mining or drilling equipment, cranes, or agricultural equipment, in energy production environments, such as oil, gas, hydro-power, wind power, solar power, and other environments. Accordingly, while certain embodiments are disclosed for specific environments, references to cooking systems should be understood to encompass any of these consumer, commercial and industrial systems for cooking, heating, curing, and treating, except where context indicates otherwise.
Provided herein is an intelligent cooking system leveraging hydrogen technology plus cloud-based value-added-services derived from profiling, analytics, and the like. The smart hydrogen technology cooking system provides a standardized framework enabling other intelligent devices, such as smart-home devices and IoT devices to connect to the platform to further enrich the overall intelligence of contextual knowledge that enables providing highly relevant value-added-services. The intelligent cooking system device (referred to herein in some cases as the “cooktop”), may be enabled with processing, communications, and other information technology components and interfaces for enabling a variety of features, benefits, and value added services including ones based on user profiling, analytics, remote monitoring, remote processing and control, and autonomous control. Interfaces that allow machine-to-machine or user-to-machine communication with other devices and the cloud (such as through application programming interfaces) enables the cooking system to contribute data that is valuable for analytics (e.g., on users of the cooking system and on various consumer, commercial and industrial processes that involve the cooking system), as well as for monitoring, control and operation of other devices and systems. Through similar interfaces, the monitoring, control and/or operation of the cooking system, and its various capabilities, can benefit from or be based on data received from other devices (e.g., IoT devices) and from other data sources, such as from the cloud. For example, the cooking system may track its usage, such as to determine when to send a signal for refueling the cooking system itself, to send a signal for re-supplying one or more ingredients, components or materials (such as based on detected patterns of usage of the same over time periods), to determine and provide guidance on usage of the cooking system (such as to suggest training or improvements in usage to improve efficiency or efficacy), and the like. These may include results based on applying machine learning to the use of the fuel, the use of the cooking system, or the like.
In embodiments, the intelligent cooking system may be fueled by a hydrogen generator, referred to herein in some cases as the electrolyzer, an independent fuel source that does not require traditional connections to the electrical power grid, to sources of gas (e.g., natural gas lines), or to periodic sources of supply of conventional fuels (such as refueling oil, propane, diesel, or other fuel tanks) The electrolyzer may operate on a water source to separate hydrogen and oxygen components and subsequently provide the hydrogen component as a source of fuel, such as an on-demand source of fuel, for the intelligent cooking system. In embodiments, the electrolyzer may be powered by a renewable energy source, such as a solar power source, a wind power source, a hydropower source, or the like, thereby providing complete independence from the need for traditional power infrastructure. Methods and systems describing the design, manufacturing, assembly, deployment, and use of an electrolyzer are included herein. Among other benefits, the electrolyzer allows storage of water, rather than flammable materials like oil, propane, and diesel, as a source of energy for powering cooking systems in various isolated or sensitive industrial environments, such as on or in ships, submarines, drilling platforms, mining environments, pipeline environments, exploration environments, agricultural environments, clean room environments, air- and space-craft environments, and others. Intelligent features of the cooking system can include control of the electrolyzer, such as remote and/or autonomous control, such as to provide a precise amount of hydrogen fuel (converted from water) at the exact point and time it is required. In embodiments, mechanisms may be provided for capturing and returning products of the electrolyzer, such as to return any unused hydrogen and oxygen into water form (or directing them for other use, such as using them as a source of oxygen for breathing).
Methods and systems describing the design, manufacturing, assembly, deployment, and use of a smart hydrogen-based cooking system are included herein. Processing hardware and software modules for operating various capabilities of the cooking system may be distributed, such as having modules or components that are located in sub-systems of the cooking system (e.g., the burners or other heating elements, temperature controls, or the like), having modules or components located in proximity to a user interface for the cooking system (e.g., associated with a control panel), having modules or components located in proximity to a communications port for the cooking system (e.g., an integrated wireless access point, cellular communications chip, or the like, or a docking port for a communications devices, such as a smart phone), having modules or components located in nearby devices, such as other smart devices (e.g., a NEST® thermostat), gateways, access points, beacons, or the like, and/or having modules or components located on servers, such as in the cloud or in a hosted remote control facility.

In embodiments, a gas burner may include an on-demand gas-LPG hybrid burner, which can burn conventional fuel like liquid propane, but which can also burn fuel generated on demand, such as hydrogen produced by the electrolyzer. In embodiments, the burner may be a consumer cooktop burner having an appropriate power capability, such as being able to produce 20,000 British Thermal Unit (“BTU”).

The user interface may include distributed components as described above for other software and hardware components.
