The present disclosure relates generally to Industrial Internet of Things IIOT) management systems. More particularly, the present disclosure relates to an edge controller for use in an IIOT management system.
IIOT management systems may be used to control operations of a variety of different facility management system components. Examples of facilities that may include an IIOT management system includes buildings, factories, industrial sites, and aircraft. Each of these different verticals often use different equipment, different communication protocols, different data, and different data formats. This can make it difficult to provide a system that can be readily deployed to control such varied systems.
The disclosure may be more completely understood in consideration of the following description of various examples in connection with the accompanying drawings, in which:
While the disclosure is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the disclosure to the particular examples described. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the disclosure.
The following description should be read with reference to the drawings, in which like elements in different drawings are numbered in like fashion. The drawings, which are not necessarily to scale, depict examples that are not intended to limit the scope of the disclosure. Although examples are illustrated for the various elements, those skilled in the art will recognize that many of the examples provided have suitable alternatives that may be utilized.
Managing a facility (e.g. a building, an industrial site, or an aircraft system) and operations related with the assets of a facility can be a tedious process for a facility manager. Typically, management of many existing facility management systems by the facility managers involves significant guess-work and assumptions because the facility managers do not possess meaningful access to information technology (IT) and operational technology (OT) data associated with the assets of the facility. Further, there often lacks a system with capability to provide to a facility manager: (a) fast, easy, and efficient access to the OT and IT data along with underlying relationships existing amongst the data; and (b) an ability to analyze the data and contextual information associated with the data, in a meaningful manner. Furthermore, many of such facilities includes thousands or even millions of assets and many end-points (e.g. sensors, PLCs, valves, lightning systems, switches, controllers etc.) and the data associated with these assets and/or points can be complex. In many cases, there are inherent data ontologies, data models, enterprise patterns, relationships, etc., associated with data that is simply too complicated to be processed by conventional systems.
What would be desirable is a system than can provide the facility manager or a facility administrator with access to relevant data that is being transacted through the assets in a facility and any meaningful relationships that can be extracted from the data. This information can be utilized by the facility manager and/or the facility administrator for various purposes, e.g., but not limited to, reducing operating expense, improving operational performance of the facility, identifying bottlenecks, anticipating maintenance need and fault, etc. What would also be desirable is such a system that can connect to a variety of diverse systems (e.g. building sub-systems for a building facility, avionic sub-systems for an aircraft facility, industrial sub-systems for an industrial plant etc.).
Various example embodiments described herein relates to an edge controller. An example edge controller is capable of: automatically discovering and identifying assets in a facility, collecting data (e.g. telemetry data and/or metadata) from diverse types of the assets of a facility, transforming the data with diverse complexities and ontologies into a unified format, and providing the transformed data to a server. In some cases, the edge controller provides the data in a format to the server that can be processed by the server to determine meaningful relationships and insights from the data. In this regard, and in some cases, the server can develop an extended object model from the data received from the edge controller. Further, in some cases, the edge controller is capable of receiving configuration information based on which various applications supported on the edge controller can be configured to control operations associated with the assets of the facility. In this regard, the users (e.g. facility managers and/or facility administrators) can utilize a user-interface (UI) associated with the server and take fast and effective data driven decisions for managing the facility, by configuring various applications on the edge controller based on the configuration information.
For on-boarding and installing existing systems (e.g. Building management systems or Industrial controllers) that can control and manage a facility, a technician or an expert is often required to physically visit the site. On-boarding such existing systems can be a complex process, requiring integration of controller systems with several complex and diverse subsystems of the facility (each of which may be operating based on in its own way and protocol). Accordingly, on-boarding and installing such existing systems can take many man-hours (weeks) of effort to get the facility ready so that its operations can be managed remotely. Also, commissioning such systems often requires halting operations, shutting down of various assets or moving sub-systems of the facility into idle mode at least temporarily, thereby, resulting in loss of productivity and throughput of the facility.
The edge controller described in accordance with various example embodiments herein, is capable of being on-boarded or commissioned remotely without a need of an expert visiting the facility. Further, and in some cases, the edge controller is based on an architecture that supports containerized packages which enables the edge controller to be on-boarded remotely within a few minutes of effort hours, irrespective of the diverse and complex subsystems of the facility to which the edge controller is to be integrated. In other words, in some cases, the edge controller is capable of being on-boarded onto a site in a plug and play manner, further details of which are described herein. This seamless on-boarding experience of installing the edge controller on site helps the facility manager to get going with managing the facility operations and making real-time data driven decisions without halting any facility operation.
Industrial Internet of Things IIOT) systems are used to control operations of a variety of different facility management system components of a facility. Examples of facilities that may include facility management system components include buildings and factories. Additional examples of IIOT systems that may include an IIOT management system include data collection, processing for aircraft maintenance, process control, factory automation, warehouse automation, manufacturing back office, worker safety devices and others. Each of these different types of facilities can produce prodigious volumes of data.
In an embodiment, a cloud 14 is operably coupled with each of the facilities 12, meaning that communication between the cloud 14 and each of the facilities 12 is enabled. Operational data such as telemetry data and optionally associated metadata can be uploaded to the cloud 14 for processing. Telemetry data can include time stamps and data values corresponding to those time stamps. Instructions such as operational set points can be determined within the cloud 14 and can be downloaded to a particular facility 12 for execution. The operational set points may include, for example, air temperature, air humidity, delta pressure (e.g. for pump, fan, or damper), pump speed, chilled water temperature, hot water temperature, etc.
In an embodiment, the cloud 14 includes a server that is programmed to communicate with the facilities 12 and to exchange data as appropriate. The cloud 14 may be a single computer server or may include a plurality of computer servers. In some embodiments, the cloud 14 may represent a hierarchal arrangement of two or more computer servers, where perhaps a lower level computer server (or servers) processes telemetry data, for example, while a higher-level computer server oversees operation of the lower level computer server or servers.
A facility 12 may include a variety of different devices and controllers that communicate in different data formats, in different languages and/or different protocols. A facility 12 may include a variety of different devices and controllers, at least some of which communicate on different types of networks. In the example shown in
A number of local devices 20, individually labeled as 20a, 20b, 20c, are operably coupled to the first network 18a via a number of controllers 22, individually labeled as 22a, 22b, 22c. While a total of three local devices 20 and controllers 22 are shown, it will be appreciated that this is merely illustrative, as there may be any number of local devices 20 and controllers 22 operably coupled to the first network 18a and may in some situations include substantially more than three local devices 20 and associated controllers 22. The local devices 20 may represent any of a variety of different types of devices that may be found within the facility 12. In an embodiment, at least some of the local devices 20 are building management system components.

In an embodiment, there is a one to one relationship between each of the local devices 20 and a corresponding one of the controllers 22. In another embodiment, one of the controllers 22 controls operation of two or more of the local devices 20. In another embodiment, one or more of the controllers 22 is built into one or more of the corresponding local devices 20, and thus is not a separate component. In another embodiment, one or more of the controllers 22 are virtual controllers that are implemented within a virtual environment hosted by one or more computing devices (not illustrated). One or more of the controllers 22 may thus be containerized. In another embodiment, at least some of the local devices 20 themselves are controllers. In such case, there may not be a separate corresponding controller 22.
A number of local devices 24, individually labeled as 24a, 24b, 24c, are operably coupled to the second network 18b via a number of controllers 26, individually labeled as 26a, 26b, 26c. While a total of three local devices 24 and corresponding controllers 26 are shown, it will be appreciated that this is merely illustrative, as there may be any number of local devices 24 and controllers 26 operably coupled to the second network 18b and may in some situations include substantially more than three local devices 24 and associated controllers 26. The local devices 24 may represent any of a variety of different types of devices that may be found within the facility 12. In an embodiment, at least some of the local devices 24 are building management system components. Examples of building management system components include sensors, actuators, valves, etc. In another embodiment, at least some of the local devices 24 are equipment within a factory. In another embodiment, at least some of the local devices 24 are industrial process control devices within an industrial process. In another embodiment, at least some of the local devices 24 are airplane devices within an airplane.
In an embodiment, there is a one to one relationship between each of the local devices 24 and a corresponding one of the controllers 26. In another embodiment, one of the controllers 26 controls operation of two or more of the local devices 24. In another embodiment, one or more of the controllers 26 is built into one or more of the corresponding local devices 24, and thus is not a separate component. In another embodiment, one or more of the controllers 26 are virtual controllers that are implemented within a virtual environment hosted by one or more computing devices (not illustrated). In another embodiment, at least some of the local devices 24 themselves are controllers. In such case, there may not be a separate corresponding controller 26.
In an embodiment, the facility 12 may include a Building Management System (BMS) controller 28 that is operably coupled with the first network 18a and the second network 18b. In another embodiment, the BMS controller 28 may be operably coupled with the first network 18a but not with the second network 18b. In another embodiment, the BMS controller 28 may be operably coupled with the second network 18b but not with the first network 18a. In an embodiment, the BMS controller 28 is a legacy controller. In another embodiment, the BMS controller 28 may be absent.
In an embodiment, an edge controller 16 is installed within the facility 12. The edge controller 16 may be considered as functioning as an intermediary between the local controllers 22, 26 and the cloud 14. For instance, in an example, the edge controller 16 can pull data from the local controllers 22, 26 and provide the data to the cloud 14. In an embodiment, the edge controller 16 is configured to discover the local devices 20, 24 and/or the local controllers 22, 26 that are connected along a local network such as the network 18. Details of discovery of assets (e.g. the local devices 20, 24) are further described herein. In an embodiment, the network protocol of the network 18 includes discovery commands that, for example, are used to request that all devices connected to the network 18 identify themselves. In some cases, the edge controller 16 is configured to discover the local devices 20, 24 regardless of an underlaying protocol supported by the local devices 20, 24. In other words, the edge controller 16 can discover various local devices 20, 24 supported by different protocols (e.g. BACnet, Modbus, LonWorks, SNMP, MQTT, Foxs, OPC UA etc.).
In an embodiment, the edge controller 16 interrogates any devices it finds operably coupled to the network 18 to obtain additional information from those devices that further helps the edge controller 16 and/or the cloud 14 identify the connected devices, such as type of building system components, functionality of the identified building system components, connectivity of the local controllers and/or building system components, types of operational data that is available from the local controllers and/or building system components, types of alarms that are available from the local controllers and/or building system components, and/or any other suitable information. For purpose of brevity, the additional information requested from the devices is referred interchangeably as, ‘metadata’, ‘semantic data’, or ‘the model data’, hereinafter throughout the description.
More generally, and in some examples, the edge controller 16 may be communicatively coupled to one or more physical assets, via one or more networks. For purpose of brevity, the term ‘physical assets’ is also referred interchangeably to as ‘data points’, ‘end points’ or ‘electronic devices’ throughout the description. According to various example embodiments described herein, the physical assets can be, for example, but not limited to, sensors, electronic components, pressure valves, HVACs, alarm units, building management systems, building controllers, industrial subsystems, industrial controllers, lightning systems, air detective systems, air quality sensors, avionic subsystems, aircraft Line-replaceable Units (LRUs), flight management systems, avionic data bus, etc. These may correspond to, for example, one or more local devices 20, 24 of
According to an example embodiment, the edge controller 16 is configured to receive at least one of, telemetry data and model data from various physical assets in a facility (e.g., but not limited to, a building, an industrial site, a vehicle, a warehouse, an aircraft etc.). In some examples, the telemetry data can represent time-series data and may include a plurality of data values associated with the assets which can be collected over a period of time. For instance, in an example, the telemetry data may represent a plurality of sensor readings collected by a sensor over a period of time. Further, the model data can represent meta-data associated with the assets. The model data can be indicative of ancillary or contextual information associated with the asset. For instance, in an example, the model data can be representative of geographical information associated with the asset (e.g. location of the asset) within a facility. In another example, the model data can represent a sensor setting based on which a sensor is commissioned within a facility. In yet another example, the model data can be representative of a data type or a data format associated with the data transacted through the asset. In yet another example, the model data can be indicative of any information which can define a relationship of the asset with one or more other assets in the facility. In accordance with various example embodiments described herein, the term ‘model data’ can be referred interchangeably as ‘semantic model’ or ‘metadata’ for purpose of brevity.
In accordance with an example embodiment, the edge controller 16 is configured to discover and identify one or more local devices 20, 24 and/or any other physical assets which are communicatively coupled to the edge controller 16. Further, upon identification of the assets, the example edge controller 16 is configured to pull the telemetry data and/or the model data from the various identified assets. In an example, these assets can correspond to one or more electronic devices that may be located on-premise in a facility. The edge controller 16 is configured to pull the data by sending one or more data interrogation requests to the assets. These data interrogation requests can be based on a protocol supported by an underlying physical asset. Examples of discovery and identification of assets in a facility are described in U.S. patent application Ser. No. 16/888,626, entitled “REMOTE DISCOVERY OF BUILDING MANAGEMENT SYSTEM METADATA”, and filed on 29 May 2020, which is incorporated herein by reference.
In accordance with said example embodiment, the edge controller 16 is configured to receive the telemetry data and/or the model data in various data formats or different data structures. In an example, a format of the telemetry data and/or the model data, received at the edge controller 16 may be in accordance with a communication protocol of the network supporting transaction of data amongst two or more network nodes (i.e. the edge controller 16 and the asset). As can be appreciated, in some examples, the various assets in a facility can be supported by one or more of various network protocols (e.g., TOT protocols like BACnet, Modbus, LonWorks, SNMP, MQTT, Foxs, OPC UA etc.). Accordingly, and in some cases, the edge controller 16 is configured to pull the telemetry data and/or the model data, in accordance with communication protocol supported by an underlaying local device controllers 20, 24 (i.e. asset).
In some cases, the edge controller 16 is configured to process the received data and transform the data into a unified data format. The unified data format is referred hereinafter as a common object model. In an example, the common object model is in accordance with an object model that may be required by one or more data analytics applications or services, supported at the cloud 14. In some cases, the edge controller 16 can perform data normalization to normalize the received data into a pre-defined data format. In an example, the pre-defined format can represent a common object model in which the edge controller 16 can further push the telemetry data and/or the model data to the cloud 14. In some examples, the edge controller 16 is configured to establish a secure communication channel with the cloud 14. In this regard, the data can be transacted between the edge controller 16 and the cloud 14, via the secure communication channel, further details of which are described herein and in particular with reference to
In some cases, the edge controller 16 is configured to perform at least one of: (a) receiving at least one of: telemetry data and the model data from the assets; (b) normalizing the received data, which can include transforming the received data from a first format into a second format that supports a common object model; and (c) sending the transformed data representative of the common object model to the cloud 14. In accordance with some example embodiments, the edge controller 16 is configured to receive and aggregate the data (e.g., but not limited to, telemetry data and/or model data) from one or more sources in a facility. In some cases, the data and/or metadata information can be received and/or pulled from multiple assets corresponding to various independent and diverse sub-systems in the facility. In some cases, the edge controller 16 aggregates some or all of the data before sending the data to the cloud. For instance, the edge controller 16 may average a plurality of sensor readings received from a particular asset (e.g. particular sensor), and only send the average sensor value rather than each individual sensor reading. Furthermore, and in some cases, the edge controller 16 is configured to normalize at least some of the received data and send the normalized data to the cloud 14. For instance, airflow readings may be normalized to duct size, or temperature readings may be normalized to degrees F. when some temperature readings are received in degrees C. These are just examples. In some cases, the edge controller 16 can send the transformed data based on a data pull request received from the cloud 14. In another example, the edge controller 16 can send the transformed data automatically at pre-defined time intervals.
In some cases, the edge controller 16 is configured to define a protocol for performing at least one of: (a) data ingress from the one or more assets to the edge controller 16; (b) data normalization (e.g. normalizing the data into a common object model) and/or data aggregation; and (c) data egress for pushing the data out from the edge controller 16 (for example, to the cloud 14). In this regard, the edge controller 16 can be configured to define one or more rules for controlling which data (i.e. the telemetry data and/or the model data) is allowed ingress by the edge controller 16 for further processing. Further, the edge controller 16 can define rules for normalizing the data in accordance with a common object model, as further described herein. In some cases, the edge controller 16 can define rules for egressing the data and/or a transformed version of the data (e.g. the normalized data) out from the edge controller 16. In some examples, the edge controller 16 can ingress the data and further push the data into a data lake (e.g. a data pipeline). In an example, the data lake can be managed by the edge controller 16 and/or the cloud 14.
In some cases, the edge controller 16 is configured to support one or more containerized packages. These containerized packages can include one or more applications, drivers, firmware's, executable files, services etc., that can be configured based on configuration information from the cloud 14. These containerized packages supported at the edge controller 16 can pull the telemetry data and/or the model data from the one or more assets in the facility. Further, in accordance with some example embodiments, the edge controller 16 is configured to utilize the containerized packages to perform one or more operations corresponding to at least one of: the data ingress, the data normalization and/or data aggregation, and the data egress, as described further herein. Furthermore, the containerized packages can be configured to control one or more operations associated with the assets of the facility.
In accordance with some example embodiments, the containerized packages can include one or more drivers that can be configured to auto-discover and identify one or more assets in a facility. In this regard, the containerized packages can enable the edge controller 16 to access the assets, identify the one or more assets based on the interrogation of the assets, and configure one or more data transaction capabilities of the assets. The data transaction capability referred to herein can indicate, for example, what data is to be pulled from a particular asset and/or how frequent data is to be pulled from the particular asset, and/or what metadata is to be pulled from the particular asset. In some cases, the containerized packages can be utilized to configure at least one of: (a) a selection of data which is to be pulled from an asset; (b) a frequency at which the data is to be pulled from an asset; (c) selection of an asset from amongst the multiple assets from which the data is to be requested by the edge controller 16; and (d) a selection of metadata associated with an asset which is to be requested by the edge controller 16. In an example embodiment, a containerized package at the edge controller 16 can include one or more of: drivers, native firmware, library files, application file, and/or executable files that can enable one or more functions as described herein, with respect to the edge controller 16.
According to some example embodiments, the containerized packages can be configured to pull the data from the assets onto the edge controller 16 by sending data interrogation requests to various assets. These data interrogation requests can be defined in a format in accordance with a network protocol supported by the particular assets. Typically, various assets of a facility may support different network protocols (e.g. IOT based protocols like BACnet, Modbus, Foxs, OPC UA, Obix, SNMP, MQTT etc.). In some example embodiments, the containerized packages are customizable and user-configurable so as to cater to any type of asset supported by any network protocol. In other words, the containerized packages can be configured to pull the data and/or the metadata from various assets regardless of the type of asset and/or the underlying network protocol for communication with the asset. In some cases, the edge controller 16 supports one or more containerized packages that can cause automatic discovery and identification of assets of various subsystems in a facility regardless of an asset type (e.g. modern sub-system or legacy sub-system, OEM manufactured, native asset etc.). An example of containerized packages of the edge controller 16 and its associated operations are further described herein and in particular with respect to
As described herein, the edge controller 16 is configured to capture the data (e.g. the telemetry data and the semantic model) from various assets in the facility. Further, in some cases, the edge controller 16 is configured to provide to the cloud 14 at least one of the data and a common object model determined from the data. In some example embodiments, the cloud 14 can further process the received data and/or the received common object model to create an extended object model (EOM). An extended object model (EOM) is representative of a data model which unifies several data ontologies, data relationships, and/or data hierarchies into a unified format. The EOM can be utilized for further data analytics and reporting one or more KPIs, contextual insights, performance, and operational insights of a facility.
In an example, the edge controller 16 can utilize one or more asset templates associated with each asset for modelling the data into the unified format (i.e. object model). As an example, an asset template defines the typical properties for assets of an asset type. For instance, in an industrial facility, an asset can be a ‘pump’ and its properties can include inlet and outlet pressure, speed, flow etc. An asset property can also define a hierarchical relationship of an asset type with its base asset type. For instance, a reciprocating pump is a special type of an asset type for a base asset-pump. Accordingly, this hierarchical information can also be added to the asset properties associated with the asset-pump. Further, the edge controller 16 can configure asset instances associated with each asset based on the configuration information. These asset instances can be configured with a common structure and defines a control logic for controlling and/or managing the operations of individual assets and its data transaction capability. In some examples, the asset instances can also define expected attributes of the asset.
In an example embodiment, the extensible object model (EOM) can include one or more knowledge graphs. In an example, the knowledge graphs can be associated with at least one of: the assets, the facility, and/or one or more operations associated to the assets of the facility. In some cases, the EOM may include a collection of application programming interfaces (APIs) that enables a seeded semantic object model (e.g. the common object model) to be extended. In some cases, the extensible object model further enables a customer's (e.g. facility provider) knowledge graph to be built subject to the constraints expressed in the customer's semantic object model. A knowledge graph describes real world entities and their interrelations, organized in a graph. A knowledge graph defines possible classes and relations of entities in a schema and enables the interrelating of potentially arbitrary entities and covers various topical domains. Knowledge graphs may include large networks of entities, their semantic types, properties, and relationships between entities. The entities may be physical entities or non-physical entities, such as data. Examples of the EOM are described in U.S. Provisional Patent application Ser. No. 63/093,121, entitled, “EXTENSIBLE OBJECT MODEL AND GRAPHICAL USER INTERFACE ENABLING MODELING”, and filed on 16 Oct. 2020, which is incorporated herein by reference.
Typically, in facilities having several assets, there may exist several inherent data ontologies, data models, enterprise patterns, relationships etc. associated with data that is pulled from the assets. For example, a building facility may include thousands or even millions of physical assets (e.g. sensors, valves, lightning units etc.) deployed within the facility. These assets may be provided by various manufacturers, and each of these assets may be transacting the data in its own way and data format. In some cases, the data models and relationships existing amongst the assets and/or data points can be complex. For example, the data pulled from the assets by the edge controller 16 can be associated with: (a) several different data ontologies; and (b) several complex data models. When manually installed and configured such a facility, unifying such complex data into a standard format and identifying existing relationships and patterns for further data analysis can be complex, involve many man-hours, and in some cases can be practically unfeasible to perform. In contrast, the edge controller 16 and/or cloud 14 can develop an EOM based on performing data processing which can include at least one of: (a) data normalization and/or data aggregation; (b) identification of several contextual relationships existing amongst the data and/or the assets; (c) identifying data patterns associated with an enterprise systems (i.e. OT data); and (d) extending the data model based on different data patterns such as, data architecture pattern, message flow pattern, enterprise data pattern etc. to identify contextual relationships amongst the assets and/or the data transacted through the assets.
In an example embodiment, at least one of the edge controller 16 and the cloud 14 is configured to utilize the common object model and/or the EOM to identify one or more of: (i) objects of interest; and (ii) objects which are not of interest for performing further data analysis. For instance, in one example, the common object model and/or the EOM can be utilized by the cloud 14 to identify a set of assets and/or end points from which more data is to be pulled onto the edge controller 16 and/or the cloud 14. In an example, the common object model and/or the EOM can be analyzed by the cloud 14 to identify one or more configuration parameters based on which the data can be pulled from the assets of a facility. In an example, the cloud 14 can utilize the common object model and/or the EOM to identify a set of assets from amongst the plurality of assets. Further, one or more applications on the edge controller 16 can pull the telemetry data and/or the model data from the identified set of assets and provide this data and/or its common object model to the cloud 14.
In some cases, an application and/or a web service on the edge controller 16 and/or the cloud 14 can utilize the EOM to identify a contextual relationship based on which it can request the edge controller 16 to pull more data from the underlying local devices 20, 24. In an example, the application and/or the web service can use this data for further analysis, e.g., but not limited to, for reporting one or more key performance indicators (KPIs) or insights associated with the facility and/or operations of the assets. Examples of reporting KPIs based on analysis of the object model data are described in U.S. Provisional Patent Application Ser. No. 63/183,930, filed on May 4, 2021, which is incorporated herein by reference.
Accordingly, for facilities having several (e.g. thousands) of data points, rather than pulling all of the data from all of the data points, the edge controller 16 and/or the cloud 14 can identify points of interests based on the common object model and/or the EOM and accordingly pull the data as per the points of interests. According to some examples, the points of interests can be indicative of at least one of: (a) a set of assets from amongst the plurality of assets from which the edge controller 16 is to pull the data and forward its corresponding object model to the cloud 14; (b) type and/or frequency of data based on which the data is to be pulled from the assets; and (c) an event (e.g. a situation in a pre-defined context) based on which the data is to be pulled from the assets. Thus, the common object model and/or the extended object model can be analyzed to selectively pull the data from the assets and/or data points for a defined context. In accordance with various example embodiments described herein, the edge controller 16 and/or the cloud 14 can perform a context discovery process to analyze the common object model and create the extended object model. Further details of the context discovery process are described herein. Furthermore, in some example embodiments, the cloud 14 can provide configuration information to the edge controller for controlling one or more operations related to assets of the facility. The configuration information can be determined based on utilizing the EOM by the cloud 14. In an example, the configuration information can be used by one or more applications (e.g. containerized packages) on the edge controller 16 to remotely start/stop an equipment of the facility or change the setpoint of an equipment to a new value.
In an example embodiment, the cloud 14 can include one or more analytic models to analyze the EOM for various purposes. For example, the cloud 14 can include one or more of: first principle models, empirical models, engineered models, user-defined models, machine-learning models, built-in functions, and/or the like, to identify one or more data-driven insights associated with the facility. These models can be developed based on: (a) utilizing pre-defined heuristics and knowledge base associated with operations of the assets of the facility; and (b) feedback loop (i.e. closed loop) from on-going operations of the assets that are based on the control logic defined by the configuration information (e.g. site configuration) received at the edge controller 16 from the cloud 14.
In some embodiments, metadata collected from devices on the network 18 can be utilized by the edge controller 16 and/or the cloud 14 to identify the devices. As described herein, metadata can include semantic model data that describes, for example, what a particular data value represents. In one example, telemetry data may report a value of 68 and a time of 4 pm. The corresponding metadata may identify that the value is a temperature reading of 68 degrees Fahrenheit that was taken at 4 pm. In some examples, metadata can also provide an indication of what an asset is and/or where the asset is located. For example, metadata may indicate that an asset is an air handling unit (AHU) installed on the 3rd floor of building number 321. In some embodiments, this metadata can instruct the edge controller 16 and/or the cloud 14 as to an expected format of data that will be provided by a particular device. It will be appreciated that types of data collected by the edge controller 16 can vary based on the particular type of the facility 12. For example, in a building having a Heating, Ventilating and Air Conditioning (HVAC) system, examples of data that may be collected include telemetry data such as time series of sensor readings, meter data, actuator position data, and control signals. Examples of sensor readings include temperatures, pressures, flow rates and the like. Examples of meter data include gas meter data and electrical meter data. Examples of control signals include plant enable signals, cooling demand signals and heating demand signals. In an example, the edge controller 16 can collect the data and sends authorized data and/or metadata to the cloud 14 while holding back the un-authorized data and/or un-authorized metadata. The un-authorized data can refer to the portion of the data which is not subscribed by the cloud 14. In another example, the un-authorized data can refer to the portion of the data to which access rights are not granted to an application or a web service on the cloud 14. In an example, the edge controller 14 can also maintain a cache to store the data and/or the metadata collected from the assets. In this regard, in case of an outage (e.g. a site outage or a network outage), the edge controller 14 can store the data in the cache and resume the data transaction operations using the data stored in the cache, once system is resumed/re-established.
In an embodiment, the edge controller 16 is configured to provide some or all of the data collected from the devices to the cloud 14. The cloud 14 can utilize this information to create a site configuration for the facility 12. In another embodiment, the edge controller 16 itself may process the information locally and/or may create the site configuration for the facility 12. In embodiments in which the edge controller 16 passes information up to the cloud 14, and the cloud creates the site configuration, the resulting site configuration may be provided from the cloud 14 to the edge controller 16. In some examples, the site configuration can be created by the cloud 14 and/or the edge controller 16 based on utilizing at least one of the common object model and/or the EOM as described herein. In an embodiment, the edge controller 16 is configured to provide appropriate local configurations to each of the controllers 22, 26 such that each of the controllers 22, 26 is best able to control operation of the local devices 20, 24 for which they are responsible. In some embodiments, the edge controller 16 may be configured to collect operational data regarding operation of the local devices 20, 24 that is initially collected by the controllers 22, 26, and may be configured to provide at least some of the collected operational data to the cloud 14.
In an embodiment, the edge controller 16 is configured to execute any of a variety of different payloads that are downloaded to the edge controller 16 from the cloud 14. In an embodiment, the edge controller 16 may include one or more installed payloads prior to installation of the edge controller 16 at the facility 12. In some embodiments, the edge controller 16 may be configured to detect or otherwise learn specifics of the local devices 20, 24, and may receive one or more particular payloads customized to the details of the local devices 20, 24 within the facility 12. The one or more particular payloads may be customized to a particular type of the facility 12. In an embodiment in which the facility 12 is a building, and the local devices 20, 24 are building management system components, the cloud 14 may download to the edge controller 16 one or more software packages customized for use with building management system components. The particular payloads may include software packages and may be considered configuration information that is downloaded to the edge controller 16 from the cloud 14. In some embodiments, the particular payloads may include a Niagara software payload, a BACnet software payload, and the like.
In some cases, the edge controller 16 is configured to host one or more containerized packages that includes instances of one or more applications configured to manage one or more operations associated with the local devices 20, 24. For instance, in an example, the containerized packages can be configured to pull the telemetry data and/or the model data from the one or more local devices 20, 24 in the facility. As an example, the edge controller 16 hosts a Docker environment that can run virtual containers on hardware executing the Linux operating system. In some embodiments, the edge controller 16 may utilize ARM's Pelion Edge framework as a distributed Docker container host. It will be appreciated that this is merely illustrative, as other virtual container and/or virtual machine environments may be used, depending on the application. In any event, when so outfitted, the configuration information may spawn and/or configure one or more of the virtual controllers on the edge controller 16. As described herein, the containerized packages can include one or more virtual controllers and/or drivers that can be configured to manage various operations associated with the devices underlying the edge controller 16. For instance, the virtual controllers can be configured to obtain device data from the one or more local devices 20, 24, format, filter and/or perform analytics on the device data and send a representation of at least some of the device data to the cloud 14. In some examples, the containerized packages can be utilized in accordance with a site configuration provided by the cloud 14 to the edge controller 16.
In some cases, the edge controller 16 can be configured to start out as a device in blank slate. In other words, the edge controller 16 at a time of installation may have required configuration information for commissioning and managing the local devices 20, 24 and/or heuristic knowledge about the assets and/or the network environment of the facility. In accordance with an example embodiment described herein, the edge controller 16 can be configured remotely by using a web service. In an example embodiment, the edge controller 16 can receive configuration information from the cloud 14 based on which it can perform various operations as described herein. Further, upon configuration, the edge controller 16 can be configured to automatically discover and identify the local devices 20, 24 in the network on which the edge controller 16 is being deployed. Said differently, the edge controller 16 can be configured to function appropriately in whatever network environment of the facility the edge controller 16 is provisioned. It will be appreciated that a benefit of the edge controller 16 as described herein is that it doesn't require a field worker and/or an on-site technician or expert to be deployed on-premise for configuring and setting up the edge controller 16 on-site, thereby saving many man-hours of effort. In an example, the configuration information can be downloaded to the edge controller 16 from the cloud 14 and/or the web service. The configuration information may include data collection functions as well as site onboarding functions. The site onboarding functions can enable the edge controller 16 to collect data from the facility 12. Further, the site on-boarding functions can also enable the edge controller 16 to facilitate onboarding or configure a connection between the edge controller 16 and the cloud 14 for providing data that is collected from the local devices 20, 24 and/or from the controllers 22, 26 for transmission to the cloud 14.
In an example embodiment, the edge controller 16 is configured to transact the data received from the local devices 20, 24 up to the cloud 14 through a secured communication channel (e.g. a VPN tunnel). In an example embodiment, a firewall 34 is positioned between the facility 12 and the Internet 36. Communications between the edge controller 16 and assets that are exterior to the facility 12 may pass through the firewall 34 and thus reach the Internet 36. In some embodiments, as will be discussed, the edge controller 16 includes a cellular capability that allows the edge controller 16 to communicate with assets that are exterior to the facility 12 before access through the firewall 34 has been granted or otherwise enabled. In an embodiment, a mobile device on-boarding block 38, which is connected or connectable to the Internet 36, may permit a user to use their smartphone or other mobile device in performing at least some of the tasks involved in setting up and configuring the edge controller 16. In an embodiment, an Offsite Access block 40, which is connected or connectable to the Internet 36, may permit a technician or other expert to work on setting up and configuring the edge controller 16 from a remote location.
In an embodiment, the cloud 14 is operably coupled to the Internet 36 such that information can be sent to the cloud 14 via the Internet 36 from other assets such as the facility assets 32, the edge controller 16, the mobile device on-boarding block 38 and the Offsite Access block 40. Information can be sent from the cloud 14 to the other assets such as the facility assets 32, the edge controller 16, the mobile device on-boarding block 38 and the Offsite Access block 40 via the Internet 36.
The illustrative cloud 14 includes a Connection Management block 42, a Security Center block 44 and a Facility Management block 46. In some embodiments, the Connection Management block 42 is configured to help with registration of the edge controller 16 as well as to orchestrate and oversee the containers that are downloaded to the edge controller 16 from the cloud 14 in order to allow the edge controller 16 to accomplish its tasks. In some embodiments, the Security Center block 44 is configured to allow a remote technician (such as that represented by the Offsite Access block 40) to be able to access the edge controller 16 when the remote technician is not at the location at which the edge controller 16 has been installed. In some cases, the Security Center block 44 can implement a secure VPN connection between the remote technician and the edge controller 16. In an embodiment, the Facility Management block 46 is configured to overseen operation of the edge controller 16, and thus oversee operation of the facility assets 32 within the facility 12.
Alternatively, or in addition, the facility management system 31 may be configured to identify when a particular processing task has been completed by a first edge controller and/or other processing resource at a first facility to produce a first output, and also recognize that a second edge controller and/or other processing resource at a second facility needs to perform the same or similar processing task (e.g. context discovery, configuration management of assets etc.). When this occurs, the facility management system 31 may request the first output from the first edge controller and direct the first output to the second edge controller. The second edge controller then need not duplicate the particular processing task that has already been performed by the first edge controller. An example of this may be when a first edge controller performs context discovery and other configuration processing tasks to configure the first edge controller for use in a first facility. Subsequently, a second edge controller may be installed at a second facility, where the second facility is equipped, configured and/or operated in a similar manner to the first facility (e.g. by the same customer). When this occurs, the cloud 14 may identity that the second edge controller is to be configured similar to the first edge controller, and in response, the cloud 14 may instruct the first edge controller to provide certain configuration and/or other files to the cloud 14, and the cloud 14 may direct these configuration files to the second edge controller. The second edge controller thus need not duplicate the processing tasks there were already performed by the first edge controller.
In the example shown in
The cloud 14 is illustrated as including a server 14a, a server 14b and a server 14c. In some embodiments, the cloud 14 may only include one or two servers, or may include four, five or more distinct servers. In some embodiments, the cloud 14 may provide distributed computing services, in which tasks can be moved from server to server as appropriate to balance workloads on each of the servers. In this way, if a particular server, say server 14a becomes heavily loaded while other servers such as the server 14b and/or the server 14c have available processing power and/or available memory space, some of the tasks currently being performed by the server 14a may be moved over to the server 14b and/or the server 14c so that the other server(s) can assist the server 14a with its current heavy workload. It will be appreciated that the relative workloads on each of the servers 14a, 14b, 14c may vary over time, such that while server 14a may be heavily loaded at a particular point in time, at other particular points in time it may be the server 14b and/or the server 14c that is heavily loaded.
In some embodiments, at least some of the workload of one or more of the servers 14a, 14b, 14c may be temporarily offloaded to one of the edge controllers 16. If for example, edge controller 16d is currently lightly loaded and has available computing capacity (e.g. under-utilized), the cloud 14 may provide the edge controller 16d with additional temporary computing tasks that the cloud 14 would otherwise have to perform. In some embodiments, and as another example, say that the facility 12d is an existing facility that is up and running, while the facility 12e is a new facility. Because the facility 12d is already up and running, it is indicative of the fact that heavy computational workload of performing context analysis and the like, has already been accomplished for the facility 12d, while this still needs to occur for the facility 12e. In this situation, the cloud 14 may instruct the edge controller 16d to assist with some of the heavy computational load that would otherwise fall upon the edge controller 16e. This may involve uploading certain data from the edge controller 16e up to the cloud 14, and then back down to the edge controller 16d for processing. As another example, formatting and other configurational tasks already accomplished by the edge controller 16d may be copied over to the edge controller 16e.
A customer service manager (CSM) creates a customer organization and site(s) within the Facility Management block 46 of the cloud 14, as indicated at block 50. This may occur offsite. A customer may have a single organization with a single site. In some embodiments, their organization may have two, three or more sites that can be geographically distinct. In some embodiments, creating the customer organization and site(s) within the Facility Management block 46 occurs after a sales associate has reviewed the potential site to ensure that the potential site will benefit from the edge controller 16 and the Facility Management block 46. The CSM may also create users and assign roles. For example, some users may have relatively greater access rights while other users may have relatively lesser access rights. A facilities manager may have greater access rights than a tenant, for example. An edge controller is then shipped to the customer site, as indicated at block 52. A facilities manager (FM) at the site receives the edge controller and any appropriate accessories at their site, as indicated at block 54. Accessories may, for example, include one or more of a mounting bracket, a wall wart, Wi-Fi antennas, cellular antennas, cables such as Ethernet cables, screws, and dust caps.
After reviewing a Quick Start Guide, the FM installs the edge controller and connects the edge controller at the site, as indicated at block 56. In some embodiments, this can include securing the edge controller to a vertical surface such as a wall or a cabinet, either directly or using a mounting bracket. The FM may attach one or more cables to the edge controller, depending on the needs of the facility assets 32 within the facility 12.
In some cases, the FM uses their smartphone or another mobile device such as a tablet, a phablet, or a laptop to connect to a Wi-Fi network that is automatically provided by the edge controller, as indicated at block 58. In some embodiments, the FM may configure the edge controller for use with the available network at the facility 12. This may include identifying an SSID, a password, a Dynamic Host Configuration Protocol (DHCP) network, etc. This may include identifying and selecting a network that provides a static IP address. The mobile device may display one or more screens that enable the FM to configure the edge controller for use with the available network. In some embodiments, the FM may be able to use their smartphone or other mobile device to scan a QR code that may be used to initiate or otherwise start an application running on the FM's mobile device that can be used in configuring the edge controller. Configuring the edge controller may include the FM confirming the appropriate location for the edge controller using one or more screens displayed by the mobile device. An example of a facilities manager using their smartphone to register their edge controller is shown in
In accordance with an example embodiment, various information useful for on-boarding and/or configuration of the edge controller 16 in the facility can be provided on a user interface (UI) of the device used by the FM. As an example, the assets of the facility that are identified based on an ‘auto-discovery’ process as described herein by the edge controller 16 can be displayed on the UI. Further, the UI can display configuration parameters that are determined based on the context discovery and/or the EOM. The FM can use the UI to: (a) select, modify, and/or provide one or more configuration parameters; and/or (b) define one or more attributes associated with these configuration parameters to configure the containerized packages and/or one or more applications on the edge controller 16. As described herein, in some cases, containerized packages and/or the one or more applications on the edge controller 16 are configured to perform at least one of: managing operations associated with the assets; defining control logic associated with the assets of the facility; and/or defining data transaction rules/logic for pulling and pushing the data through the assets.
Further, in accordance with said example embodiment, once communication is established between a remote technician and the edge controller, the remote technician completes a software service deployment to the edge controller, as indicated at block 62. The remote technician does not need to be at the facility 12 but can instead access the edge controller remotely (as indicated by the Offsite Access block 40 shown in
As can be seen, each VSE 92 includes a Linux machine 100 that executes appropriate software to provide the functionality of the VSE 92. The VSE's 92 includes an HMI (human machine interface) module 102, a PLC (programmable logic controller) 104 and an Historian 106. The security center 96 includes an EPO/SEPM (e-policy orchestrator or Symantec endpoint protection) module 108, an SIEM (security information and event management) module 110, a WSUS (Windows server update services) computer program and network service module 112 and an Active Directory 114.

In
The edge controller 133 includes a controller 138 that is operatively coupled to the network communication port 135, the cellular communication port 136 and the device communication port 137. The controller 138 receives configuration information over the cellular communication port 136 and installs the received configuration information on the edge controller 133. The installed configuration information configures the controller 138 of the edge controller 133 to obtain the device data from the one or more local devices 20, 24 and to send a representation of at least some of the device data to the cloud 14. In some embodiments, the configuration information, once installed, configures the controller 138 to establish communication with the cloud 14 via the network communication port 135. In some embodiments, the configuration information includes one or more commands, and the controller 138 is configured to execute the one or more commands. In some cases, the configuration information may spawn and/or configure one or more of virtual controllers on the edge controller 133. In some cases, the one or more virtual controllers may be configured to obtain the device data from the one or more local devices, format, filter and/or perform analytics on the device data and send a representation of at least some of the device data to the remote server. A virtual controller, if implemented, may be defined by a virtual controller image, and wherein the configuration information may include the virtual controller image.
In some cases, the controller 138 may include control logic 139 that at least selectively provides closed loop control over a function of one or more of the local devices 20, 24, and is configured to receive and execute control commands provided by the cloud 14 for controlling one or more of the local devices 20, 24. In some cases, the control logic may be implemented as part of one or more virtual controllers spawned on the edge controller 133. In some embodiments, closed loop control may be implemented in a chiller plant, using an understanding of system dynamics and cooling demands in a particular building, both of which may be learned from the device data that is sent over time to the cloud 14. Closed loop control may include resetting chilled water supply temperatures and delta pressure set points, for example.
The configuration information may define at least in part the representation of at least some of the device data that is sent to the cloud 14. In an embodiment, the device data obtained from the local devices 20, 24 includes a plurality of data items each having a data item format, and wherein the configuration information defines which of the plurality of data items are used in constructing the representation of at least some of the device data that is sent to the cloud 14. In some cases, the configuration information defines a data format for the representation of at least some of the device data that is sent to the cloud 14. The configuration information may define one or more local data analytics executed by the controller 138 that are used to produce the representation of at least some of the device data that is sent to the cloud 14. In some embodiments, one or more local data analytics may include one or more of processing at least some of the device data (e.g. calculate average, mean, standard deviation, etc.), filtering at least some of the device data to only send meaningful data, formatting at least some of the device data, and parsing at least some of the device data. In some cases, it is desirable to reduce the amount of data sent to the cloud 14 to reduce bandwidth requirements, while still allowing the cloud 14 to perform its desired function.
In some cases, data exiting the local devices 20, 24 may be in particular formats that are governed or otherwise dictated by the architecture of the particular local devices 20, 24. In some embodiments, the controller 138 of the edge controller 133 may translate or otherwise modify the data such as telemetry data received from the local devices 20, 24 into a standard format for uploading to the cloud 14. In some embodiments, the facility 12 may include a separate gateway such as a Niagara gateway that performs a first translation of the data for the edge controller 68, such as into a Niagara compatible format. The edge controller 68 may receive the first translated data from the Niagara gateway and perform a second translation of first translated data for the cloud 14, and in particular for the Facility Management block 46 that resides within the cloud 14. Accordingly, the edge controller 68 may push the data based on the second translation to the cloud 14.
Once the cellular connection has been established, one or more software packages are downloaded from the remote server to the edge controller, and are installed on the edge controller, as indicated at block 146. The software packages may include, for example, one or more virtual controllers implemented as containers or the like. The software packages may configure the edge controller for the particular application at hand. In an embodiment, the edge controller periodically checks to see if a Wi-Fi connection is available, as indicated at decision block 148. Determining that a Wi-Fi connection is available includes detecting that an appropriate port has been opened through the facility's firewall. In other embodiments, determining that a Wi-Fi connection is available may include a Wi-Fi radio within the edge controller detecting the presence of an available Wi-Fi network, regardless of whether the presence of the available Wi-Fi network a result of a firewall port is being opened, a Wi-Fi network being established within the facility, or any other reason. While the decision block 148 is illustrated as being immediately downstream to the block 146, it will be appreciated that this is merely illustrative. In some embodiments, the edge controller periodically checks for an available Wi-Fi network.
If the edge controller determines at the decision block 148 that Wi-Fi is available, control passes to a decision block 150. As indicated by the decision block 150, the edge controller determines whether the available Wi-Fi is adequate for use by the edge controller. In an embodiment, this determination is based at least in part upon whether the available Wi-Fi provides sufficient bandwidth for the needs of the edge controller in downloading software packages, uploading data and/or downloading control commands from the remote server. In other embodiments, this determination may include other factors such as but not limited to Wi-Fi signal stability, signal strength and the like. Like the decision block 148, the decision block 150 does not represent a one-time decision but rather represents an ongoing periodic check.
If the edge controller determines at the decision block 148 that there is no Wi-Fi availability, or if the edge controller determines at the decision block 150 that any available Wi-Fi network is not adequate for the needs of the edge controller, control passes to block 152, where the edge controller maintains the cellular connection between the edge controller and the remote server. If the edge controller determines at the decision block 150 that the available Wi-Fi network is adequate, the edge controller switches to a Wi-Fi connection, as indicated at block 154. In an embodiment, switching to a Wi-Fi connection includes activating the network communication port 135 (
Control then passes to block 156, where the edge controller is connected to a Facility Management system. In an embodiment, the edge controller discovers the edge devices, such as the local devices 20, 24 shown in
Control passes to block 176, where the edge controller processes the data that will be uploaded to the server. In some embodiments, processing the data includes deciding what data to transmit. It will be appreciated that depending on the particular facility the data is coming from, there may be an immense volume of data, and it may not be feasible to simply transmit everything. In some cases, the data is processed to create various representative values such as means, medians, modes, averages, moving averages, standard deviations and/or other statistical parameters that help to explain and/or characterize the received data. The data may be processed to detect trends in the data, and only information identifying the detected trends may be uploaded. In some embodiments, at least some of the data processing may actually occur within the edge devices, which can reduce the total volume of data that is even received by the edge controller, much less uploaded to the remote server.
Control passes to decision block 178, where the edge controller decides whether it is time to upload data to the server. In an example embodiment, data may be uploaded to the server in accordance with a predefined schedule. In another example embodiment, data may be uploaded to the server any time that one or more of the parameters represented by the data changes more than a particular or predefined amount, or any time one of the parameters exceeds (or drops below) a particular or predefined threshold. If the edge controller determines that it is time to transmit data, control passes to block 180 and the data is uploaded to the server. Otherwise, the edge controller continues to check to see if it is time to transmit data.
Responsive to determining which one or more parameters to optimize, a determination is made as to one or more set point values, as indicated at block 196. These are set point values that will be transmitted to the edge controller, and thus to the appropriate edge devices, in order to control the appropriate edge devices to optimize the selected one or more parameters. At block 198, the set point values are transmitted to the edge controller for distribution to the appropriate edge devices. It will be appreciated that closed loop control means that the edge devices will provide updated data indicating the current status of the facility, or the current status of individual edge devices within the facility periodically so that set point values can be varied as appropriate to optimize the selected parameter(s), as indicated at block 200. The cycle continues on any appropriate cadence. In one embodiment, updated data indicating current status and subsequent determination of new set point values in order to optimize the selected parameter(s) occurs every 15 seconds, or every 15 minutes. Between these update times, the edge controller and/or edge devices may implement a local control loop that controls the facility in accordance with the current set point value(s).
As a result of the methods 140, 170, 190 shown in
The received configuration information is installed on the edge controller, wherein the installed configuration information configures the edge controller to obtain desired device data from the one or more local devices and to send a representation (e.g. a common object model) of at least some of the device data to the remote server, as indicated at block 244. Once the received configuration information is installed on the edge controller, the edge controller obtains the device data from the one or more local devices and sends a representation (e.g. common object model) of at least some of the device data to the remote server, as indicated at block 246. In an example, as described herein, the edge controller can normalize the data into a unified format, before sending it to the remote server. In an embodiment, representation of at least some of the device data may be sent to the remote server over the cellular communication port of the edge controller or the network communication port.
In some embodiments, the edge controller may at least selectively provide closed loop control over a function of one or more of the local devices. In an example embodiment, the edge controller can perform the closed loop control based on the configuration information received from the remote server. In an example embodiment, as described herein, the edge controller may receive the configuration information from the remote server based on analyzing of the EOM and/or the common object model by the remote server. In some embodiments, the edge controller executes control commands provided by the remote server for controlling one or more of the local devices, as indicated at block 248. In some embodiments, the edge controller implements a virtual controller, wherein the virtual controller includes one or more virtual containers or virtual machines, and wherein the virtual controller is defined by a virtual controller image. In some embodiments, the configuration information downloaded to the edge controller from the remote server includes the virtual controller image.
In the example shown, the cloud 274 includes a number of different applications or modules. As illustrated, the cloud 274 includes a Building Applications module 276, an Aero Applications module 278, and a generic Other Applications module 280. The cloud 274 includes a TS Database 282, a Blob Storage module 284, a Services module 286, a Kafka module 288 and an MQTT Broker module 290. It will be appreciated that each of the modules 284, 286, 288 and 290 are merely illustrative, and are not intended to be limiting in any fashion as any equivalent modules are contemplated as well. The Blob Storage module 284 provides data storage capabilities, and may include Microsoft® Azure Blob storage, which permits storage of unstructured data within Microsoft's cloud platform. The Kafka module 288 pertains to data streaming and may include Apache Kafka, which provides a unified, high-throughput, low-latency platform for handling real-time data feeds. The MQTT Broker module 290 serves as a go-between between the cloud 274 and the site 272. The MQTT Broker module 290 receives all messages from sites and then routes the messages to the appropriate destination client. To illustrate, any data incoming to the cloud 274 passes through the MQTT Broker module 290 before being passed to one or more appropriate modules within the cloud 274. Similarly, any data outgoing from the cloud 274 passes through the MQTT Broker module 290 before being downloaded to the site 272.
The site 272 includes an edge gateway controller 300. The edge gateway controller 300 may be considered as being an example of the edge controller 16, 68, 133. The edge gateway controller 300 includes a Link container 202 that serves as a clearinghouse for messages and other data passing between the edge gateway controller 300 and the cloud 274. The edge gateway controller 300 includes an MQTT broker 304. The illustrative data management system 270 is configured to work with any of a variety of different types of facilities. Accordingly, the edge gateway controller 300 may be considered as a “blank slate” that is capable of running any of a variety of different Docker containers (or virtual machines) that are customized to the site 272. In some embodiments, the edge gateway controller 300 may use ARM's Pelion Edge framework as a distributed Docker container host. The Pelion Edge framework may be used on a variety of Commercial Off-The-Shelf (COTS) gateways as well as on custom-built edge gateway hardware as long as there is support for Linux and adequate storage capabilities and processing power. This allows the edge gateway controller 300 to be scaled up or down, depending on the needs of a particular site 272.
In the example shown, a Niagara framework container 306 is used to collect data from many different building management systems. The Niagara framework container 306 is configured to normalize data from over two hundred different building management system protocols into a common format suitable for the cloud 274. It will be appreciated that if the site 272 includes devices on a network other than a Niagara network, then the Niagara framework container 306 would be supplemented with or replaced by a different type of network framework container. A Matrikon Dispatch container 308 is used for collecting and normalizing industrial process data in an Open Packaging Conventions (OPC) format typically used in that industry. Another container (not shown in this drawing) is used to collect and normalize aircraft data. As shown, the Niagara framework container 306 is able to communicate with a JACE and other devices 310 while the Dispatch container 308 is able to communicate with a Dispatch and other devices 312.
The edge gateway controller 300c includes a storage module 320 that is configured to communicate with an Airline Bulk Data Storage module 322. The Airline Bulk Data Storage module 322 receives airplane maintenance and operational data from an airplane 324 through an Edge to Edge Data Collector 326. In some embodiments, the Airline Bulk Data Storage module 322 may receive substantial volumes of data from a particular airplane 324 at some point after the particular airplane 324 lands, rather than receiving data during flight. While a single airplane 324 is illustrated, it will be appreciated that a particular airline has tens, hundreds or even thousands of airplanes that are operational. It will also be appreciated that when even a single airplane 324 is operational, that single airplane 324 generates a prodigious amount of operational data. In some cases, the edge gateway controller 300c includes an AERO Airflow (dispatch adaptor) that sits between the Link container 302 and the Dispatch container 308.
In some cases, the context discovery process can provide a solution to these requirements. According to an example embodiment, the edge controller 16 can perform the context discovery process. In an alternate embodiment, the context discovery process can be performed at the cloud 14. In yet another alterative embodiment, the context discovery function can be distributed among the edge controller 16, the cloud 14 and/or any other components or devices as desired.
In some example embodiments, the edge controller 16 can perform preparation of input data that is to be used for performing the context discovery process. In this regard, along with data polled from the end points, the edge controller 16 can aggregate and contextual information associated with the end points and/or the data transacted by the end points. Examples for deriving data from assets in constrained environments are described in U.S. Pat. No. 10,643,136, entitled- “SYSTEM FOR DERIVING DATA IN CONSTRAINED ENVIRONMENTS”, filed on 27 Apr. 2015, which is incorporated herein by reference. In some examples, the contextual information identified by the edge controller 16 can be utilized for building a semantic model associated with a facility. In some examples, the semantic model can be utilized by the cloud 14 for performing data analytics (e.g., but not limited to, deriving various insights related to operation or asset condition in the facility). In an example embodiment, the context discovery process can provide identification of assets and formulation of a unified representation of the assets which can be further used for developing the semantic model for a facility (e.g. a building, an industrial facility etc.).
Typically, an organization or an OEM or an equipment supplier can use its own naming/nomenclating or defining a naming identifier for an asset and/or a point which is used for its identification within a network of assets. In other words, there can be different naming conventions or formats for the same asset and/or point used by different vendors or equipment suppliers. Accordingly, several assets (e.g. sensors, HVACs, sub-systems etc.) having a same asset type within a facility can be identified by different naming conventions. Said differently, in some examples, a naming convention adopted by a first equipment manufacturer for a same asset type (e.g. AHU) can be different from a naming convention used by a second equipment manufacturer.
In some cases, there can be different nomenclatures for naming a unitary type asset which can include a single electronic equipment (e.g. sensor) and another type asset can include more than one electronic equipment (e.g. sensor and a control valve). In some cases, an air handling unit (AHU) unit can be identified based on different names/labels by different third-parties (e.g. customers, vendors, or OEM suppliers). In this regard, in an example embodiment, regardless of different naming conventions, the context discovery process can enable identification of assets (e.g. the AHU unit) within a particular asset class in accordance with a unified or standard nomenclature by the edge controller 16 and/or the cloud 14. Further, the context discovery process can cater to identification of any asset type and the equipment associated to that asset type.
In some examples, an asset within a facility can either be a standalone equipment or may include more than one component. In some examples, various electronic components associated with a physical asset can be referred to as data points. In other words, while the electronic components are also physical assets, but for purpose of brevity, these electronic components can be referred to as data points through which the physical asset can pull or poll data. As an example, an AHU can be associated with a room temperature sensor and a cooling valve unit. In this example, by way of implementation of the context discovery process, the AHU can be identified as a physical asset and the room temperature sensor and the cooling valve can be identified as data points of the AHU. In an example, the context discovery process can enable identification of existing or potential relationships amongst various assets or end points. For instance, the context discovery process can identify that the room temperature sensor and the cooling valve unit and/or its respective operations or functioning is associated to the same AHU. In some example embodiments, the edge controller 16 can identify based on context discovery one or more physical assets (e.g. plant controllers, building controllers) and the electronic components that may be further coupled to the physical assets (e.g. sensors, valves etc.). The context discovery process can also enable identification of mapping (e.g. relationship or association) amongst the physical assets and the data points. According to various example embodiments described herein, the edge controller 16 can perform identification of a count of end points in accordance with each category of asset type by performing the context discovery. As an example, in an industrial facility, the edge controller 16 can identify multiple assets such as, a hot water plant which can further include multiple assets, e.g., but not limited to, first boiler, second boiler, first pump, second pump etc. In some example embodiments, the context discovery process can also enable identification of different asset types within a family of assets. For example, the context discovery process can enable identification of different controllers (e.g., but not limited to, a unitary controller, a plant controller) that may be present within a family of controllers located at a facility.
In an example embodiment, the context discovery process can be performed by the edge gateway controller 300. In an example, a method of context discovery can include performing a tokenization process to identify various electronic components and/or data points from an asset nomenclature (e.g. name of an asset). The tokenization process can include splitting the asset nomenclature (e.g. a tag name) into multiple sub-parts and identifying these sub-parts as individual electronic components or data points. The tokenization process can also include identification of relationships existing amongst the points. In an example, a facility can include a master asset e.g. a controller and multiple data points associated with the master asset. In this regard, the master asset can be identified higher in an asset hierarchy of the facility with respect to end points/other assets to which the master asset is associated. For example, the asset hierarchy can include a building system controller which can be communicatively coupled to various electronic components such as, HVAC subsystems, sensors, lighting sub-systems) etc. located within a facility. An example of tokenization process can be based on a TRIE algorithm that can include finding a tree of nodes in a network of nodes representing a tag name which includes a common identifiable portion of a point name (i.e. asset name). In some examples, tokenization includes identifying aspect values from a point row representative of a point name. More details of the TRIE algorithm for tokenization are described in U.S. patent application Ser. No. 13/912,682 and entitled—“SYSTEM AND METHOD TO CLASSIFY TELEMETRY FROM AUTOMATION SYSTEMS”, which is incorporated herein by reference.
The illustrative context discovery process 330 includes a context discovery box 332 which receives a point list from, for example, either an EBI site 334 or a Tridium gateway 336. The illustrative context discovery box 332 includes a Reference Ontology 338, a Tokenizer 340, an NN Model 342 and a Training Data Set 344. In some examples, utilization of the NN model 342 in the context discovery process may include using a training dataset of point names and utilizing a neural network and/or machine learning to develop a model for identification of assets of the facility. The context discovery box 332 also includes a Reasoning block 346. The context discovery box 332 outputs from the Reasoning block 346 a point to equipment mapping, a list of asset types and a list of point roles. In some examples, the point roles may represent identification of a meaning of an end-point (e.g. a physical asset or data point) in a machine readable format. In some examples, the point roles may be associated with an aspect property which indicates a meaning of that point role and can have a finite list of values/attributes. For instance, in an example, a data point can represent an AHU which can have a point role such as, discharge air, i.e. that asset is functioned to discharge air from one point to another. Further, the point role discharge air can have aspect values such as signal type, temperature, air, etc. In some examples, there may or may not be a relationship between aspect properties for a point role. According to some example embodiments, the point role and the aspect types associated with an end point can be utilized in the context discovery process for identification of the asset. In some examples, the aspect values associated with the point role can be utilized by the edge controller 16 to filter and identify the data to be pulled from or transacted through the data point.
In accordance with some example embodiments, the output of the context discovery box 332 can be provided to a Model Editor 348. An engineer 350 provides information to the Model Editor 348 and to a BCG spreadsheet 352. The Model Editor 348 outputs to an Asset Registry 354 and a Sky Spark OBS 356. Additional details regarding identifying point roles are described in U.S. 2014/0032555, which application is incorporated herein by reference. In some case, the context discovery box 332 is configured to identify a type of device that is sending the data and/or how the device is connected to other devices in the system hierarchy from the context of the received data, such as the data syntax, point names referenced in the data, device names referenced in the data, data type referenced in the data, quality of the received data and/or any other suitable information. A further description of an illustrative context discovery method and system is included in the U.S. Provisional Patent Application Ser. No. U.S. 63/137,302, and entitled “CONTEXT DISCOVERY SYSTEM AND METHOD”, which is incorporated herein by reference.
In an embodiment, an edge controller 416 is installed at the facility 412 such that the edge controller 416 is able to learn the identity and features of each of the facility assets 432 (and on-premises facility control system 440) and is able to oversee operation of one or more of the facility assets 432, sometimes through the on-premise facility control system 440. In an embodiment, the edge controller 416 has one or more LAN ports 442 for communicating with the local facility assets 432, sometimes through the on-premise facility control system 440. In some cases, one or more LAN switches/routers 444 are provided to provide an interface between one or more of the LAN ports 442 of the edge controller 416 and a LAN that connected to one or more of the facility assets 432 sometimes through the on-premise facility control system 440.
In an example embodiment, the edge controller 416 is configured to transact the data received from the local facility assets 432 up to the cloud 414 through a secured communication channel (e.g. a VPN tunnel). In an example embodiment, the edge controller 416 includes one or more WAN ports 446, such as an Ethernet port and/or a cellular port (e.g. 4G). A firewall 434 is positioned between the facility 412 and the Internet 436. Communications between the edge controller 416 and cloud 414 may pass through the firewall 434.
In some embodiments, as will be discussed, the edge controller 416 may include a cellular capability such as a 4G cellular port that allows the edge controller 416 to communicate with assets that are exterior to the facility 412 before access through the firewall 434 has been granted or otherwise enabled by the IT staff at the facility. When so provided, the cellular port may gain access to the cloud 414 through a global private Access Point Name (APN) connection as shown. This may allow the setup, configuration and/or operation of the edge controller 416 before access through the firewall 434 has been granted or otherwise enabled by the IT staff at the facility, which can significantly reduce the setup time of the system.
It is contemplated that the edge controller 416 may execute a cybersecurity management block 450, which in some cases may be a virtual security engine (VSE) based on the ICS Shield™ product available from Honeywell International Inc. ICS Shield™ provides a top-down operational technology (OT) security management solution for securing connected industrial control system (ICS) environments with multiple physical sites and multiple automation equipment types. It also enables secure management of remote field assets through a single security operations center.
The edge controller 416 may also host a number of software drivers 462. The software drivers 462 may include, for example, BMS drivers such as BACnet and MODBUS for communicating with and in some cases auto discovering the facility assets 432 in the facility 412. The software drivers 462 may include other drivers such as Niagara™ drivers (N4 drivers) for communicating with, for example, a Java Application Control Engine (JACE) of a Niagara™ BMS framework available from the Tridium Corporation. It is contemplated that the software drivers 462 may include OPC, SQL/XML and/or any other suitable drivers.
In some cases, the edge controller 416 is configured to support one or more containerized packages 470. These containerized packages 470 can include one or more applications, drivers, firmware's, executable files, services etc., that can be configured based on configuration information from the cloud 414. These containerized packages 470 can generate alarms, tag certain data collected from the local facility assets 432, generate metadata from the data collected from local facility assets 432, filter data collected from the local facility assets 432, normalize certain data collected from the local facility assets 432, and perform configuration, management, backup and restore functions of the edge controller 16. These are just example functions that may be supported by the containerized packages 470 of the edge controller 416.
In some cases, the containerized packages 470 supported at the edge controller 416 can pull telemetry data and/or model data from the one or more of the local facility assets 432 in the facility 412. Further, in accordance with some example embodiments, the edge controller 416 utilizes the containerized packages 470 to perform one or more operations corresponding to at least one of: data ingress, data normalization and/or data aggregation, and data egress, as described further herein. Furthermore, the containerized packages 470 can be configured to control one or more operations associated with the local facility assets 432 of the facility 412, sometimes through the on-premise facility control system 440.
In accordance with some example embodiments, the containerized packages 470 can include or implement one or more of the software drivers 462 mentioned above. The software drivers 462 can, for example, auto-discover and identify one or more the local facility assets 432 of the facility 412, sometimes through or using the on-premise facility control system 440. In this regard, the containerized packages 470 can enable the edge controller 416 to access the local facility assets 432, identify the one or more local facility assets 432 based on the interrogation of the local facility assets 432, and configure one or more data transaction capabilities of the local facility assets 432. The data transaction capability referred to herein can indicate, for example, what data is to be pulled from a particular asset and/or how frequent data is to be pulled from the particular asset, and/or what metadata is to be pulled from the particular asset. In some cases, the containerized packages 470 can be utilized to configure at least one of: (a) a selection of data which is to be pulled from an asset; (b) a frequency at which the data is to be pulled from an asset; (c) selection of an asset from amongst the multiple assets from which the data is to be requested by the edge controller 416; and (d) a selection of metadata associated with an asset which is to be requested by the edge controller 416. In an example embodiment, a containerized package 470 at the edge controller 416 can include one or more of: drivers, native firmware, library files, application file, and/or executable files that can enable one or more functions as described herein, with respect to the edge controller 16.
According to some example embodiments, the containerized packages 470 can be configured to pull the data from the local facility assets 432 onto the edge controller 416 by sending data interrogation requests to various local facility assets 432. These data interrogation requests can be defined in a format in accordance with a network protocol supported by the particular asset(s). Typically, various local facility assets 432 of a facility 412 may support different network protocols (e.g. IOT based protocols like BACnet, Modbus, Foxs, OPC UA, Obix, SNMP, MQTT etc.). In some example embodiments, the containerized packages 470 are customizable and user-configurable so as to cater to any type of asset supported by any network protocol. In other words, the containerized packages 470 can be configured to pull the data and/or the metadata from various local facility assets 432 regardless of the type of asset and/or the underlying network protocol for communication with the asset. In some cases, the edge controller 416 supports one or more containerized packages 470 that can cause automatic discovery and identification of local facility assets 432 of various subsystems in a facility 412 regardless of an asset type (e.g. modern sub-system or legacy sub-system, OEM manufactured, native asset etc.). An example of containerized packages 470 of the edge controller 416 and its associated operations are further described herein and in particular with respect to
In some cases, the cloud 414 is configured to analyze at least some of the data collected by the cloud 414 and provide control commands back to the facility 412 based on the analysis. In some cases, this analysis may be offered as part of a Software-As-A-Service (SAAS). A remote web interface 480 may be used to provide an interface to the cloud 414. The remote web interface 480 may be used to, for example, monitor the data collected by the cloud 414, configure the cloud 414 to perform certain functions for a particular facility 412 (e.g. as a SAAS), and configure the edge controller 416 to perform certain functions (such as download certain containerized packages tailored to a particular facility 412). These are just some examples. In the example shown, a cloud-based management block 482 provides an interface between the cloud 414 and the edge controller 416 that, for example, a remote technician can interact with the edge controller 416, often through the cloud 414. In some cases, the cloud 414 may include a mobile device on-boarding block, which permits a user to use their smartphone or other mobile device 490 to perform at least some of the tasks involved in setting up and configuring the edge controller 416, as shown in for example

Aspects of the present disclosure may be embodied in a special purpose computer and/or data processor that is specifically programmed, configured, and/or constructed to perform one or more of the computer-executable instructions explained in detail herein. While aspects of the present disclosure, such as certain functions, may be described as being performed exclusively on a single device, the present disclosure also may be practiced in distributed environments where functions or modules are shared among disparate processing devices, which are linked through a communications network, such as a Local Area Network (“LAN”), Wide Area Network (“WAN”), and/or the Internet. Similarly, techniques presented herein as involving multiple devices may be implemented in a single device. In a distributed computing environment, program modules may be located in both local and/or remote memory storage devices.
Aspects of the present disclosure may be stored and/or distributed on non-transitory computer-readable media, including magnetically or optically readable computer discs, hard-wired or preprogrammed chips (e.g., EEPROM semiconductor chips), nanotechnology memory, biological memory, or other data storage media.

Such communications, for example, may enable loading of the software from one computer or processor into another, for example, from a management server or host computer of the mobile communication network into the computer platform of a server and/or from a server to the mobile device. Thus, another type of media that may bear the software elements includes optical, electrical, and electromagnetic waves, such as used across physical interfaces between local devices, through wired and optical landline networks and over various air-links. The physical elements that carry such waves, such as wired or wireless links, optical links, or the like, also may be considered as media bearing the software. As used herein, unless restricted to non-transitory, tangible “storage” media, terms such as computer or machine “readable medium” refer to any medium that participates in providing instructions to a processor for execution.
