Aspects of the present invention generally relate to the fields of networked computerized industrial control, automation systems, networked computerized systems utilized to monitor, log, and display relevant manufacturing/production events and associated data, and supervisory level control and manufacturing systems. More particularly, aspects of the present invention relate to systems and methods for persisting location data corresponding to process control devices in a historian system. Aspects of the present invention also relate to systems and methods for filtering state indicia of process control devices based on location data.
Historian systems capture and/or historize data about continuous processes, such as production status, performance monitoring, quality assurance, tracking, and product delivery. The historian system data can be accessed via remote devices, such as a smartphone or a tablet computing device. Conventional systems and methods rely on a human (e.g., an operator, a user, etc.) to manually search for data corresponding to particular process devices based on a name of the process device within the historian system. Reliance on manually entered searches leads to inefficient process management due to the requirement for the user to know the name of a particular process unit within the historian system.
Aspects of the invention persist a location of a data source in a historian system to facilitate filtering state indicia including the data source based on a location of a remote user device.
In an aspect, a historian system includes a historian data server adapted to store one or more data values and geolocation metadata associated with the data values. The data values represent a state of a process unit within a continuous process and the location metadata represents a geolocation of the process unit. The historian system also includes an engine communicatively coupled to the historian data server and adapted to generate state indicia, which corresponds to a location attribute including the geolocation metadata, based on the data values. And the historian system includes a state indicia server communicatively coupled to the engine. The state indicia server is adapted to store the generated state indicia in a memory storage device and receive a query from a remote user device via a communication network. The query includes a current geolocation of the remote user device. The state indicia server is further adapted to transmit the stored state indicia to the remote user device via the communication network in response to receiving the query when the current geolocation of the remote user device matches the location attribute of the state indicia.
A method embodying aspects of the invention provides a dynamic graphical representation of a process unit state within a continuous process. The method includes receiving, by a server computing device, one or more data values from a process unit within a continuous process adapted to generate the data values. The data values represent a state and geolocation of the process unit. The method also includes generating, by an engine of the server computing device, a dynamic graphical representation of the process unit state based on the data values and providing, by the server computing device, the dynamic graphical representation to the remote user device via a communication network. The dynamic graphical representation includes a location property comprising the geolocation of the process unit and the server computing device provides it in response to a request from the remote user device such that the remote user device filters the dynamic graphical representation based on the location property and a spatial proximity parameter relative to a current geolocation of the remote user device.
In another aspect, a method of distributing tag value alert notifications to a user device via a communication network includes receiving, by a server, a tag from a historian system via a communication network. The server comprises a processor and a memory storage device and the tag comprises a plurality of data values representing a state of a process unit within a continuous process and a location of the process unit. The method further includes storing the received tag and an alert configuration corresponding to a remote user on the memory storage device. The alert configuration comprises a proximity radius relative to a user device associated with the remote user and a threshold value corresponding to at least one of the plurality of data values representing the state of the process unit. The method also includes receiving, by the server, a current location of the user device over the communication network and transmitting, by the server, an alert notification over the communication network to the user device when a distance between the location of the process unit and the current location of the user device is within the proximity radius and the data value exceeds the threshold value. Reception of the alert notification causes the user device to display the alert notification and access the tag stored on the memory storage device over the communication network.
Other objects and features will be in part apparent and in part pointed out hereinafter.

The historian publishers 106 of
The historian system 108 is adapted to store data received from historian publishers 106 and a location of each process device 102. Persisting the location data in this manner enables server 112 and/or remote device 114 to filter state indicia based on the location data. In an embodiment, historian system 108 stores location data as extended properties. For example, extended properties may be used to store metadata about tags and data sources 104. In another embodiment, historian system 108 indexes extended properties to facilitate searching of tags and/or the extended properties. Searching may be done within existing clients, such as the Browser Client in Wonderware® Online provided by Schneider Electric, for example. In another embodiment, a location property is configured within a state indicator that contains the location of the first process device 102 within the state indicator. The location may be changed via historian manager 118 and/or connector 120.
The engine 110 is adapted to generate state indicia representing a state of process devices 102. In an embodiment, engine 110 creates a dynamic graphical representation of the data generated by process devices 102 to indicate performance metrics of the process devices 102. An exemplary engine 110 is Wonderware® SmartGlance provided by Schneider Electric. In an embodiment, state indicia is referred to as a report.
The server 112 is adapted to store state indicators generated by engine 110 and allow access to the stored state indicators by remote device 114. In an embodiment, server 112 receives a query from remote device 114 that includes a location parameter. For example, the location parameter may be a current location (e.g., latitude and longitude) of remote device 114 or a location entered via a map, a text box, and the like (e.g., address, radius parameter, postal code, city, etc.). The server 112 filters the stored state indicators based on the location parameter of the query. In an embodiment, server 112 determines which state indicators include location data that is an exact match of the location parameter of the query. In another embodiment, server 112 determines which state indicators include location data that indicate location of a process device 102 being within a predetermined distance of the location parameter of the query (e.g., within a radial distance of 5 kilometers). In an embodiment, server 112 filtering state indicators based on the location parameter of the query reduces the amount of data returned to remote device 114 via communication infrastructure 122.
The remote device 114 is adapted to retrieve state indicators from server 112, receive alerts from server 112, and generate user interfaces including the state indicators. For example, remote device 114 may be a mobile computing device, a smartphone, a tablet computing device, a laptop computing device, a smartwatch computing device, or the like. In an embodiment, remote device 114 executes an application as further described herein. In another embodiment, remote device 114 includes a GPS antenna to provide a geolocation (e.g., latitude and longitude) of remote device 114.
The definition database 116 is adapted to store definitions of state indicators. In an exemplary embodiment, definitions stored by definition database 116 define a format of state indicators when displayed on remote device 114. In an embodiment, a state indicator is configured and uploaded to definition database 116 by historian manager 118. For example, historian manager 118 may be Wonderware® Online provided by Schneider Electric. In another embodiment, a state indicator is configured and uploaded to definition database 116 by connector 120. For example, connector 120 may be an on-premise tool (e.g., available on a computing device at and/or near the continuous process) that allows users to configure SmartGlance reports and upload them to a SmartGlance server (e.g., server 112).

Embodiments of the present invention may comprise a special purpose computer including a variety of computer hardware, as described in greater detail below.
Embodiments within the scope of the present invention also include computer-readable media for carrying or having computer-executable instructions or data structures stored thereon. Such computer-readable media can be any available media that can be accessed by a special purpose computer. By way of example, and not limitation, such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage, or other magnetic storage devices, or any other medium that can be used to carry or store desired program code means in the form of computer-executable instructions or data structures and that can be accessed by a general purpose or special purpose computer. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a computer, the computer properly views the connection as a computer-readable medium. Thus, any such connection is properly termed a computer-readable medium. Combinations of the above should also be included within the scope of computer-readable media. Computer-executable instructions comprise, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing device to perform a certain function or group of functions.
The following discussion is intended to provide a brief, general description of a suitable computing environment in which aspects of the invention may be implemented. Although not required, aspects of the invention will be described in the general context of computer-executable instructions, such as program modules, being executed by computers in network environments. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. Computer-executable instructions, associated data structures, and program modules represent examples of the program code means for executing steps of the methods disclosed herein. The particular sequence of such executable instructions or associated data structures represent examples of corresponding acts for implementing the functions described in such steps.
Those skilled in the art will appreciate that aspects of the invention may be practiced in network computing environments with many types of computer system configurations, including personal computers, hand-held devices, multi-processor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, and the like. Aspects of the invention may also be practiced in distributed computing environments where tasks are performed by local and remote processing devices that are linked (either by hardwired links, wireless links, or by a combination of hardwired or wireless links) through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
An exemplary system for implementing aspects of the invention includes a special purpose computing device in the form of a conventional computer, including a processing unit, a system memory, and a system bus that couples various system components including the system memory to the processing unit. The system bus may be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. The system memory includes read only memory (ROM) and random access memory (RAM). A basic input/output system (BIOS), containing the basic routines that help transfer information between elements within the computer, such as during start-up, may be stored in ROM. Further, the computer may include any device (e.g., computer, laptop, tablet, PDA, cell phone, mobile phone, a smart television, and the like) that is capable of receiving or transmitting an IP address wirelessly to or from the internet.
The computer may also include a magnetic hard disk drive for reading from and writing to a magnetic hard disk, a magnetic disk drive for reading from or writing to a removable magnetic disk, and an optical disk drive for reading from or writing to removable optical disk such as a CD-ROM or other optical media. The magnetic hard disk drive, magnetic disk drive, and optical disk drive are connected to the system bus by a hard disk drive interface, a magnetic disk drive-interface, and an optical drive interface, respectively. The drives and their associated computer-readable media provide nonvolatile storage of computer-executable instructions, data structures, program modules, and other data for the computer. Although the exemplary environment described herein employs a magnetic hard disk, a removable magnetic disk, and a removable optical disk, other types of computer readable media for storing data can be used, including magnetic cassettes, flash memory cards, digital video disks, Bernoulli cartridges, RAMs, ROMs, solid state drives (SSDs), and the like.
The computer typically includes a variety of computer readable media. Computer readable media can be any available media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer readable media may comprise computer storage media and communication media. Computer storage media include both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Computer storage media are non-transitory and include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, SSDs, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired non-transitory information, which can accessed by the computer. Alternatively, communication media typically embody computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media.
Program code means comprising one or more program modules may be stored on the hard disk, magnetic disk, optical disk, ROM, and/or RAM, including an operating system, one or more application programs, other program modules, and program data.
