2. Discussion of the Related Art
Offline condition monitoring devices are built on a Real Time Operating System, (RTOS), such as Microsoft Windows CE RTOS. This operating system differs from normal multi-tasking operating systems, such as Windows, iOS, Android, Linux, and the like, in that the RTOS is intended to serve “real-time” application requests. This means that during critical system tasks, external events (such as screen updates, or mouse clicks etc.) can be “masked out” until that critical task is complete. If this was not the case, then real-time data would suffer “jitter” whenever external events (or interrupts) were received by the processor.
Although Real Time Operating Systems (RTOS's) are amazingly configurable, it is common practice to limit the default user interface of these operating systems to just a few basic controls, or worse, no user controls. This limitation imposes a requirement to the system builder (the firmware creator) to design and implement their own “custom user interface” to complement the RTOS firmware.
Much as this custom user interface philosophy will work with devices such medical equipment; vending machines; automotive dashboard controllers; point of sale and ticket dispensers; electronic test equipment, etc. the downside is that there is little to no commonality between devices at the user interface level. This, in turn, not only adds to the expense of developing the system, it also necessitates the need for additional user training once that system is ready and deployed for use.
What is desired is a “best of both worlds” solution wherein offline condition monitoring data can be collected using “off the shelf” tablet computers (which employ common and familiar operating systems), but which, at the same time, can communicate to hardware components using a Real Time Operating System (RTOS).
The present invention is directed towards an adaptation enabling an interface between “off the shelf” tablet computers, portable computers, or other browser enabled computing devices and monitoring or operational controllers employing a Real Time Operating System (RTOS).
A first aspect of the present invention introduces a user interface and operating control system for a machine condition monitoring analysis device, the system comprising:
a machine condition monitoring analysis device including:
In a second aspect, the Operation System (OS) can be a Real Time Operating System (RTOS).
In another aspect of the present invention, the communication circuit operates in accordance with a wired communication protocol. The wired communication protocol can be Ethernet, Universal Serial Bus (USB), and the like.
In yet another aspect of the present invention, the communication circuit operates in accordance with a wireless communication protocol. The wireless communication protocol can be Wi-Fi, Bluetooth, Highway Addressable Remote Transducer (HART), and the like.
It is noted that the Wi-Fi Alliance defines Wi-Fi as any “wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards”.
It is noted that Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Bluetooth was originally conceived as a wireless alternative to the wired RS-232 data communication protocol. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 20,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. Bluetooth was standardized under IEEE 802.15.1.
In yet another aspect of the present invention, the machine condition monitoring analysis device is configured with at least one of a media access control address (MAC address) and an Internet Protocol address (IP address).
It is noted: The media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.
It is also noted: The IP Address is a numerical label assigned to each device (e.g., computer, printer, tablet, scanner, and the like) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. The role of the IP Address has been characterized as follows: “A name indicates what we seek. An address indicates where it is. A route indicates how to get there.”
In yet another aspect, the machine condition monitoring analysis device further comprises a portable power supply, wherein the portable power supply can be provided in a format of a battery, a super capacitor, and the like.
In yet another aspect of the present invention, the machine condition monitoring analysis device further comprises a recharging circuit for recharging the portable power supply. The recharging circuit can employ a wireless recharging circuit, a solar energy converter, a motion energy generator, and the like.
In yet another aspect, the machine condition monitoring analysis device is integrated into a wireless network.

In yet another aspect, the machine condition monitoring analysis device is arranged in indirect wireless communication with a tablet or other portable computing device, wherein the communication is linked through a network bridge or a wireless gateway. The wireless gateway can be a dual band wireless gateway.
In yet another aspect, the machine condition monitoring analysis device is adapted for use as a network bridge.
In yet another aspect, the system can further comprise at least one wireless Highway Addressable Remote Transducer (HART) enabled device.
It is noted: HART (Highway Addressable Remote Transducer) Protocol is the global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring system. More specifically, HART is a bi-directional communication protocol that provides data access between intelligent field instruments and host systems. A host can be any software application from technician's hand-held device or laptop to a plant's process control, asset management, safety or other system using any control platform.
In yet another aspect, the machine condition monitoring analysis device and the tablet can be integrated into a single assembly by a system cradle.

The machine condition monitoring analysis device (microlog analyzer) 100 additionally includes several elements for interfacing with condition monitoring sensors. A first element is a tachometer and external power 130. The tachometer and external power 130 can provide power to sensors and/or receiver power from an external source. The tachometer and external power 130 can additionally or alternatively acquire a rotational speed of a rotating element of a monitored machine. A second element is an analog input 132. The exemplary embodiment includes a number of analog inputs 132 to accommodate a sufficient number of sensors for monitoring a machine or other device. In the exemplary embodiment, each exemplary analog input 132 includes a pair of analog channels. Additionally, one or more wireless receivers or transceivers can be integrated into the machine condition monitoring analysis device (microlog analyzer) 100 for receiving data from wireless machine condition monitoring sensors. Each of the various elements for interfacing with condition monitoring sensors would be in signal communication with the microprocessor 162 of the analyzer printed circuit assembly (PCA) 160. Each of the tachometer and external power 130, the at least one analog input 132, the one or more wireless receivers or transceivers, and any other machine condition monitoring sensor interfaces would be in electrical communication with the analyzer printed circuit assembly (PCA) 160 by wires, a wiring harness and respective connectors, a flexible circuit, and the like. The microprocessor 162 would receive data provided by each of the various machine condition monitoring sensors, analyze the received data, and provide an output accordingly.
The machine condition monitoring analysis device (microlog analyzer) 100 can include a ventilation and/or cooling system 140. The ventilation and/or cooling system 140 can be provided in any suitable configuration, including vents formed through one or more of the panels, cooling fans located proximate heat generating elements, cooling fans located proximate vents through one of the panels, cooling fins in thermal communication with heat generating elements of the analyzer printed circuit assembly (PCA) 160, a liquid cooling system (although considerations for power consumption, etc. should be considered) and the like.
Functionality of the machine condition monitoring analysis device (microlog analyzer) 100 is provided by a set of digital instructions, often referred to as software, firmware, and the like. The digital instructions set is written to be run on a specific platform or operating system. The machine condition monitoring analysis device (microlog analyzer) 100 employs an Operating System (OS) 170. The OS 170 operates in conjunction with an embedded web server 172. In one implementation, the OS 170 can be a Real Time Operating System (RTOS).
The user would provide requests through an external portable computing device (illustrated as an exemplary tablet/portable computing device 200), as illustrated in an exemplary block diagram shown in
The tablet/portable computing device 200 includes at least one user interface. The portable computing device touch display 212 provides both a machine output and a user input for communicating with the user. A portable computing device tactile user input 214 can be integrated into the tablet/portable computing device 200, wherein the portable computing device tactile user input 214 provides an additional user input capability. The portable computing device tactile user input 214 can be provided in any configuration, including a single tactile button; multiple tactile buttons in any format, such as a keyboard; a pointing device, such as a trackball, a track-pad, and the like; or any other suitable configuration. Although a tablet is illustrated in the various figures, it is understood that the tablet is representative of the tablet/portable computing device 200, wherein the tablet/portable computing device 200 can be any suitable portable computing device empowering an appropriate wireless communication protocol and web based software.
The machine condition monitoring analysis device (microlog analyzer) 100 and tablet/portable computing device 200 would preferably communicate with one another by way of an analyzer and portable computing device communication link 520, as illustrated in the exemplary schematic diagram presented in
The web server 172 interacts with and processes externally provided HTTP web requests 510 provided by the tablet/portable computing device 200 and returns formatted web pages 512 to the request originator. The web requests 510 provided by the tablet/portable computing device 200 provides the required operating instruction set to the microprocessor 162 of the machine condition monitoring analysis device (microlog analyzer) 100. The microprocessor 162 recognizes, interprets, and processes the web requests 510 provided through the tablet/portable computing device 200. Configuration of the machine condition monitoring analysis device (microlog analyzer) 100 would be based upon the provided web requests 510. This provides several significant advantages over a currently provided firmware based solution. The web server based system introduces significant flexibility to the end user. The flexibility enables ease of adaptation of the machine condition monitoring analysis device (microlog analyzer) 100 for virtually any reasonable machine condition monitoring configuration; with an understanding of the limitations defined by the number of analog inputs 132 of the machine condition monitoring analysis device (microlog analyzer) 100, the types and locations of the machine condition monitoring sensors, and the like.
In operation: “Out of the Box” the machine condition monitoring analysis device (microlog analyzer) 100 will include a “default” configuration. The user would then access the concealed wired network communication port 134, and directly connect a computing device, such as a personal computer (PC), a laptop computer, or any other wired communication enabled computing device to the concealed wired network communication port 134. The user would then launch an Internet browser on the connected computing device, and enter either a default name or an Internet Protocol (IP) Address of the machine condition monitoring analysis device (microlog analyzer) 100. A configuration web page would then be generated by the machine condition monitoring analysis device (microlog analyzer) 100 and displayed within the Internet browser. From this configuration web page, the user could then assign a unique name to the device, as well as configure all aspects of its network settings (for example, setting security key or should the unit remember existing connections).
Assuming that this internal configuration data for the machine condition monitoring analysis device (microlog analyzer) 100 is lost, the user would then hold down the system reset button 124 for a predetermined period of time, such as five seconds. Holding down the system reset button 124 for a predetermined period of time will force the system reset indicator 126 to illuminate. It is preferred that the system reset indicator 126 would emit a red colored light, as this would be consistent with an expected result. Then, with the system reset button 124 still depressed, pressing the analyzer power switch 120, will power-cycle the machine condition monitoring analysis device (microlog analyzer) 100 and return the machine condition monitoring analysis device (microlog analyzer) 100 to the default factory state.
Once correctly configured, wirelessly connecting any tablet/portable computing device 200 to the machine condition monitoring analysis device (microlog analyzer) 100 would involve little more than identifying the given wireless access name of the machine condition monitoring analysis device (microlog analyzer) 100 and connecting to it. However, as this would limit the network functionality of the tablet/portable computing device 200, a second wireless network card within the machine condition monitoring analysis device (microlog analyzer) 100 would allow it to also wirelessly connect to any existing network infrastructure, thereby allowing access to whatever online resources (such as maintenance or historian data) is actually available.
Connectivity between the machine condition monitoring analysis device (microlog analyzer) 100 and the tablet/portable computing device 200 can be provided in a number of configurations. A first exemplary configuration was described above, wherein the machine condition monitoring analysis device (microlog analyzer) 100 and the tablet/portable computing device 200 are connected in a direct peer to peer configuration, as illustrated in
A second exemplary configuration is provided by an indirect connection, as illustrated in
The system operates by providing web requests from the tablet/portable computing device 200 to the machine condition monitoring analysis device (microlog analyzer) 100. In the exemplary embodiment illustrated in
A configuration where machine condition sensors attached to each analog input 132 are known and represented by the analog input 132.
The system would preferably include a plurality of wireless Highway Addressable Remote Transducer (HART) enabled devices 400. Each wireless Highway Addressable Remote Transducer (HART) enabled device 400 includes a machine condition sensing system (not shown but understood by description) and a HART protocol transceiver 450 assembled within a HART enabled device housing 410. The HART protocol transceiver 450 is a transceiver operating in accordance with the HART protocol. The HART protocol transceiver 450 is capable of transmitting a HART communication transmission 451 and receiving an incoming signal from another device also operating in accordance with the HART protocol. The machine condition sensing system monitors the specific condition of the machine and returns the respective condition data to the intermediary communication device 300. The wireless Highway Addressable Remote Transducer (HART) enabled device 400 can continuously monitor the machine condition and transmit the associated machine condition data or monitor the machine condition upon request. The request would originate from the machine condition monitoring analysis device (microlog analyzer) 100. The machine condition monitoring analysis device (microlog analyzer) 100 would emit a wireless communication transmission 151, which is received by the first band wireless communication system 350. The intermediary communication device 300 would decode and interpret the signal received from the wireless communication system 150 and in turn transmit an appropriate HART communication transmission 355 from the Highway Addressable Remote Transducer (HART) 354, wherein the HART communication transmission 355 is directed towards a specific HART enabled device housing 410. The instruction set obtained from the wireless communication transmission 151 is translated from the inbound wireless communication protocol to an instruction set and embedded within a signal in accordance with the HART protocol. The instruction set is forwarded to the wireless Highway Addressable Remote Transducer (HART) enabled device 400 by way of the HART device and dual band wireless gateway communication link 530. The signal containing the embedded instruction set is transmitted as a HART communication transmission 355 from the Highway Addressable Remote Transducer (HART) 354. The emitted HART communication transmission 355 is received by the HART protocol transceiver 450 of the wireless Highway Addressable Remote Transducer (HART) enabled device 400. The wireless Highway Addressable Remote Transducer (HART) enabled device 400 decodes the HART communication transmission 355 and operates in accordance with the associated instruction set. Once the machine condition data is acquired, the wireless Highway Addressable Remote Transducer (HART) enabled device 400 forwards the information to the machine condition monitoring analysis device (microlog analyzer) 100 through the intermediary communication device 300.
In the exemplary embodiment, the wireless Highway Addressable Remote Transducer (HART) enabled device 400 would return the data to the intermediary communication device 300 by way of the HART device and dual band wireless gateway communication link 530. The HART device and dual band wireless gateway communication link 530 is established between the Highway Addressable Remote Transducer (HART) 354 of the intermediary communication device 300 and the HART protocol transceiver 450 of the wireless Highway Addressable Remote Transducer (HART) enabled device 400. The Highway Addressable Remote Transducer (HART) 354 emits a HART communication transmission 355, which is received by the HART protocol transceiver 450 and the HART protocol transceiver 450 emits a HART communication transmission 451, which is received by the Highway Addressable Remote Transducer (HART) 354. The intermediary communication device 300 translates the received signal from the HART protocol to the associated gateway protocol and forwards the machine condition data to the machine condition monitoring analysis device (microlog analyzer) 100 for analysis.
The data received from the wireless Highway Addressable Remote Transducer (HART) enabled device 400 is transferred to the machine condition monitoring analysis device (microlog analyzer) 100 for analysis by way the analyzer and dual band wireless gateway communication link 532. In the exemplary embodiment, the machine condition data is transferred from the intermediary communication device 300 to the machine condition monitoring analysis device (microlog analyzer) 100 by way of the analyzer and dual band wireless gateway communication link 532. The analyzer and dual band wireless gateway communication link 532 is established between the first band wireless communication system 350 of the intermediary communication device 300 and the wireless communication system 150 of the machine condition monitoring analysis device (microlog analyzer) 100. The first band wireless communication system 350 emits a first band wireless communication transmission 351, which is received by the wireless communication system 150. The machine condition monitoring analysis device (microlog analyzer) 100 decodes the machine data embedded within the first band wireless communication transmission 351. The machine condition monitoring analysis device (microlog analyzer) 100 would analyze the machine condition data and generate one or more web pages 512. The generated one or more web pages 512 are conveyed to the tablet/portable computing device 200 either through the intermediary communication device 300, as illustrated in
In the first exemplary configuration (
In the second exemplary configuration (
The machine condition monitoring analysis device (microlog analyzer) 100 and tablet/portable computing device 200 are integrated into a single solution for monitoring, obtaining, and analyzing machine conditions. It is understood that it would be advantageous to provide a device to combined both the machine condition monitoring analysis device (microlog analyzer) 100 and tablet/portable computing device 200 into a single assembly for ease of use, transport, and portability, as introduced in the illustration presented in
The disclosed system provides several advantages over the currently available machine condition monitoring solutions. Initially, the disclosed system allows any portable computing device, including a laptop, a tablet computer, a smart phone, and the like to display live condition monitoring data as web data returned from a “real time” (RTOS) data collection system acting as a web server. Additionally, the disclosed system allows “real time” condition monitoring applications to be constructed on common operating systems devices such as “off the shelf” laptop or tablet computers, thereby reducing UI complexity and user training requirements. This increases time to market, reduces development costs, improves user operation, among other advantages.
