The operation, maintenance, and repair of machinery in today's modern factories results in a large amount of digital data and information being generated and stored across multiple information systems. If information about a machine, a process, a collection of machines involved in a process, or the like is desired, the relevant information is identified, retrieved, and rendered for use by an operator. Machine/process-specific information may be stored in different information systems, at least some of which may be remotely located from a factory environment. Depending on the level of integration between these different systems, an operator may be required to utilize multiple different software applications to access multiple systems to obtain the desired information. This information retrieval process from multiple disparate systems is time-consuming and error-prone, potentially leading to a mismatch between a physical machine or process and the data that is retrieved. Technical solutions that address these and other drawbacks associated are discussed herein.
The detailed description is set forth with reference to the accompanying drawings. The drawings are provided for purposes of illustration only and merely depict example embodiments of the disclosure. The drawings are provided to facilitate understanding of the disclosure and shall not be deemed to limit the breadth, scope, or applicability of the disclosure. In the drawings, the left-most digit(s) of a reference numeral identifies the drawing in which the reference numeral first appears. The use of the same reference numerals indicates similar, but not necessarily the same or identical components. However, different reference numerals may be used to identify similar components as well. Various embodiments may utilize elements or components other than those illustrated in the drawings, and some elements and/or components may not be present in various embodiments. The use of singular terminology to describe a component or element may, depending on the context, encompass a plural number of such components or elements and vice versa.
This disclosure relates to, among other things, devices, servers, systems, methods, computer-readable media, techniques, and methodologies for retrieving information relating to a machine or a process involving the machine, generating a digital representation of the retrieved information, and rendering the digital representation within a factory environment on top of or otherwise in proximity to the machine using a computer-mediated-reality-based technology. Computer-mediated-reality-based technologies that may be used include, without limitation, virtual reality technologies, augmented reality technologies, mixed reality technologies, or the like.
In certain example embodiments, a user 102, such as a machine operator, may be present within the factory floor environment 100. In conventional factory environments, an operator typically accesses machine/process-specific information using a user device such as a desktop or laptop computer, a tablet, a smartphone, or the like. More specifically, in conventional factory environments, an operator typically utilizes one or more remote terminals to access multiple information systems potentially via multiple software applications. This conventional information retrieval process is time-consuming and prone to error if, for example, the various information systems are not well-integrated, potentially causing an operator to not match the physical machine correctly with the digital data.
Example embodiments of the disclosure eliminate the need for the user 102 to utilize a remote computer or terminal to access machine/process-specific information while present in the factory floor environment 100 by utilizing a computer-mediated-reality-based technology to identify the machine/process-specific information and render a digital representation of the information on top of or otherwise in proximity to a corresponding machine. In this manner, physical machines serve as proxies to available digital information that is relevant to their operation and/or to processes involving such machines. In particular, a physical machine serves as a gateway to identifying digital information relating thereto such that the information can be rendered as a virtual overlay superimposed on a real-world view of the machine within the factory floor environment 100.
In certain example embodiments, the generation and rendering of the digital representation in the use case of
Upon receiving the user input indicative of a user selection of a particular machine, an object recognition algorithm may be executed to identify the machine. For example, a back-end server may receive the user input indicative of a user selection of a machine and execute the object recognition algorithm to identify the type of machine or the particular machine itself. In certain example embodiments, the user 102 may not be required to provide any separate user input but may simply direct the wearable device towards the selected machine such that the machine is in the field-of-view of the transparent display of the wearable device. The wearable device may then capture an image of the real-world view visible through the display and send the captured image to a back-end server for object recognition processing.
In addition to, or as an alternative to, virtual overlays rendered within a real-world factory environment, a digital representation of information relating to a machine or process may be rendered within a control room environment in certain example embodiments of the disclosure. For example, digital representations may be rendered as overlays on an image of the factory floor environment that is being displayed in a control room environment. In other example embodiments, a complete virtual representation of the factory floor environment may be generated and rendered on a display in a control room environment. Virtual overlays containing machine/process-specific information may then be superimposed on the virtual representation of the factory floor environment.
Each operation of either of the methods 300 or 400 may be performed by one or more components that may be implemented in any combination of hardware, software, and/or firmware. In certain example embodiments, one or more of these component(s) may be implemented, at least in part, as software and/or firmware that contains or is a collection of one or more program modules that include computer-executable instructions that when executed by a processing circuit cause one or more operations to be performed. A system or device described herein as being configured to implement example embodiments of the invention may include one or more processing circuits, each of which may include one or more processing units or nodes. Computer-executable instructions may include computer-executable program code that when executed by a processing unit may cause input data contained in or referenced by the computer-executable program code to be accessed and processed to yield output data.
Referring first to
In certain example embodiments, the user input 202 indicative of a selection of a particular machine may be received as a result of a user directing a line-of-sight (gaze) of a wearable device, such as a head-mounted display, towards the machine. In yet other example embodiments, the user input 202 may be automatically generated as a result of a proximity sensor detecting user presence within a threshold distance of a particular machine. A wearable device and/or a machine within the factory floor environment may contain the proximity sensor. Alternatively, or additionally, a proximity sensor may be provided within the factory floor environment but not as part of any particular machine. It should be appreciated that, in certain example embodiments, a user selection of a particular machine may not be required to initiate processes described herein for rendering digital information in proximity to the machine using a computer-mediated-reality-based technology. Rather, such information may be rendered in connection with all (or some subset thereof) of machines in the factory floor environment on a continuous or periodic basis without the need for user selection of a particular machine. In such example embodiments, a user may nonetheless be able to control what information is rendered. For example, a user may be provided with the capability to cease the rendering of digital information for a machine if so desired. Further, in other example embodiments, the digital information may be rendered on top of or otherwise in proximity to a particular machine if, for example, an alarm or error condition is detected for the machine.
Upon receiving the user input 202 indicative of a user selection of a particular machine, one or more object recognition modules 206 may execute an object recognition algorithm at block 304 of the method 300 to identify the selected machine. For example, a back-end server may receive the user input 202 indicative of a user selection of a machine and execute the object recognition algorithm to identify the type of machine or the particular machine itself. For example, in certain example embodiments, a user may direct the wearable device towards the selected machine such that the machine is visible through the transparent display of the wearable device. The wearable device may then capture an image of the real-world view visible through the display and send the captured image to a back-end server for object recognition processing.
After object recognition is performed to identify the selected machine, an identification 208 of the recognized machine may be provided to one or more information retrieval modules 210. The machine identification 208 may be, for example, an identifier that identifies the type of machine or that uniquely identifies the particular machine itself. Computer-executable instructions of the information retrieval module(s) 210 may be executed at block 306 of the method 300 to retrieve, from one or more datastores 212, information 214 that is relevant to the selected machine or a process involving the selected machine and potentially one or more other machine. The machine/process related information 214 that is retrieved may include, without limitation, real-time operational data for the machine and/or a process involving the machine; cost data; repair data; data identifying error or alarm conditions associated with the machine's operation; power consumption data; and so forth. The information retrieval module(s) 210 may provide the retrieved information 214 as input to one or more digital representation generation modules 216.
At block 308 of the method 300, computer-executable instructions of the digital representation generation module(s) 216 may be executed to determine an access level associated with the user. More specifically, the digital representation generation module(s) 216 may access the datastore(s) 212 using a user identifier or the like to retrieve user access level data 218 indicative of an access level associated with the user. In certain example embodiments, the user identifier may be received from a wearable device to which the identifier is linked. In other example embodiments, the user identifier may be obtained via another mechanism such as from a key card, key fob, or the like that the user used to gain access to the factory floor environment.
At block 310 of the method 300, computer-executable instructions of the digital representation generation module(s) 216 may be executed to generate a digital representation 224 of the retrieved information 214 based at least in part on an access level of the user as indicated by the user access level data 218. The digital representation generation module(s) 216 may provide the digital representation 224 as input to one or more rendering modules 226. In certain example embodiments, the access level of the user may allow the user to access all of the retrieved information 214. In such example embodiments, the digital representation 224 may contain any of the retrieved information 214. In other example embodiments, the user may have a more restrictive level of access. For example, different levels of access may be associated with different user roles (e.g., a manager vs. a service technician). In such example embodiments, some portion of the retrieved information 214 may be excluded from the digital representation 224 so as not to provide the user with information that the user is not permitted to view based on her level of access.
At block 312 of the method 300, computer-executable instructions of the rendering module(s) 226 may be executed to render the digital representation 224. The rendered digital representation 228 may take the form of an overlay that is rendered on a display of a wearable device that is transparent to a real-world environment. In other example embodiments, the rendered digital representation 228 may be a projection of the digital representation 224 onto a surface of the machine or a surface that is proximity to the machine. In still other example embodiments, the rendered digital representation 228 may be an overlay that is superimposed on an image of the factory floor environment being displayed on a control room environmental display or a virtual overlay on a virtual representation of the factory floor environment. In any of the use cases described above, a factory floor operator or a control room operator is provided with real-time information about a machine or process involving the machine, where such information is rendered on top of or otherwise in close proximity to the machine itself, thereby reducing the amount of time that was necessary to access such information using conventional information retrieval systems and allowing the operator to make time-critical, on-the-spot decisions on the factory floor. In addition, example embodiments of the disclosure eliminate information retrieval errors such as data/machine mismatches that occur in connection with conventional information retrieval systems utilized in factory floor environments.
In certain example embodiments, information contained in the digital representation 224 may be prioritized based on various criteria and the digital representation 224 may be rendered in a manner that reflects this prioritization. Referring now to
At block 404 of the method 400, computer-executable instructions of the prioritization module(s) 220 may be executed to prioritize a first portion of the retrieved information 214 over a second portion of the retrieved information 214 based at least in part on the operational state of the machine. For example, information identifying operational parameters of the machine (e.g., power consumption, efficiency, temperature data, etc.) may be prioritized over information indicating a number of components processed by the machine per unit time. As another non-limiting example, information indicative of an alarm or error condition associated with the machine may be prioritized above all other information. It should be appreciated that while an operational state of the machine is described as an example basis for prioritization, any other criteria may be used. For example, the access level of the user may be used to prioritize information within the digital representation 224.
The prioritization module(s) 220 may generate priority data 222 indicative of the prioritization determined at block 404 and provide the priority data 222 to the digital representation generation module(s) 216. The digital representation generation module(s) 216 may utilize the priority data 222, at least in part, to generate the digital representation 224. At block 406 of the method 400, computer-executable instructions of the rendering module(s) 226 may be executed to render the digital representation in a manner that reflects the prioritization indicated by the priority data 222. For example, that portion of the information deemed to have the highest priority may be most prominently displayed (e.g., larger font, bolded, etc.) as compared to information deemed to have a lesser priority. In certain example embodiments, information that is deemed to have a priority level below a threshold value, may be excluded entirely from the rendered digital representation 228. In certain example embodiments, the prioritization module(s) 220 may provide the priority data 22 directly to the rendering module(s) 226, which may adjust the rendering of the digital representation 224 to reflect the prioritization indicated by the priority data 222.

The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire.
Computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device.
Computer readable program instructions for carrying out operations of the present disclosure may be assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. The computer readable program instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user's computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present disclosure.
Aspects of the present disclosure are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions.
These computer readable program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. These computer readable program instructions may also be stored in a computer readable storage medium that can direct a computer, a programmable data processing apparatus, and/or other devices to function in a particular manner, such that the computer readable storage medium having instructions stored therein comprises an article of manufacture including instructions which implement aspects of the function/act specified in the flowchart and/or block diagram block or blocks.
The computer readable program instructions may also be loaded onto a computer, other programmable data processing apparatus, or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer implemented process, such that the instructions which execute on the computer, other programmable apparatus, or other device implement the functions/acts specified in the flowchart and/or block diagram block or blocks.
The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions.
