The Internet of Things (IoT) is a network of interconnected objects (or Things), hereinafter referred to as IoT devices, that produce data through interaction with the environment and/or are controlled over a network. An IoT platform is used by application developers to produce IoT applications for the IoT devices. Generally, IoT platforms are utilized by developers to register and manage the IoT devices, gather and analyze data produced by the IoT devices, and provide recommendations or results based on the collected data. As the number of IoT devices used in various sectors increases, the amount of data being produced and collected has been increasing exponentially.

Enterprise integration layer 210 can be configured to serve clients or local applications with information and services to support a variety of enterprise-level applications. For example, enterprise control applications 226 can be configured to provide subsystem-spanning control to a graphical user interface (GUI) or to any number of enterprise-level business applications (e.g., accounting systems, user identification systems, etc.). Enterprise control applications 226 may also or alternatively be configured to provide configuration GUIs for configuring Cloud IoT controller 266. In yet other embodiments, enterprise control applications 226 can work with layers 210-220 to optimize the IoT environment based on inputs received at interface 207 and/or IoT device interface 209.
IoT device integration layer 220 can be configured to manage communications between Cloud IoT controller 266 and the IoT devices 228. For example, IoT device integration layer 220 may receive sensor data and input signals from the IoT devices 228, and provide output data and control signals to the IoT devices 228. IoT device integration layer 220 may also be configured to manage communications between the IoT devices 228. IoT device integration layer 220 translate communications (e.g., sensor data, input signals, output signals, etc.) across a plurality of multi-vendor/multi-protocol systems.
Integrated control layer 218 can be configured to use the data input or output of IoT device integration layer 220 to make control decisions. Due to the IoT device integration provided by the IoT device integration layer 220, integrated control layer 218 can integrate control activities of the IoT devices 228 such that the IoT devices 228 behave as a single integrated supersystem. In some embodiments, integrated control layer 218 includes control logic that uses inputs and outputs from a plurality of IoT device subsystems to provide insights that separate IoT device subsystems could not provide alone. For example, integrated control layer 218 can be configured to use an input from a first IoT device subsystem to make a control decision for a second IoT device subsystem. Results of these decisions can be communicated back to IoT device integration layer 220.
Automated measurement and validation (AM&V) layer 212 can be configured to verify that control strategies commanded by integrated control layer 218 are working properly (e.g., using data aggregated by AM&V layer 212, integrated control layer 218, IoT device integration layer 220, FDD layer 216, and/or the like). The calculations made by AM&V layer 212 can be based on IoT device data models and/or equipment models for individual IoT devices or subsystems. For example, AM&V layer 212 may compare a model-predicted output with an actual output from IoT devices 228 to determine an accuracy of the model.
Fault detection and diagnostics (FDD) layer 216 can be configured to provide on-going fault detection for the IoT devices 228 and subsystem devices (equipment, sensors, and the like), and control algorithms used by integrated control layer 218. FDD layer 216 may receive data inputs from integrated control layer 218, directly from one or more IoT devices or subsystems, or from another data source. FDD layer 216 may automatically diagnose and respond to detected faults. The responses to detected or diagnosed faults can include providing an alert message to a user, a maintenance scheduling system, or a control algorithm configured to attempt to repair the fault or to work-around the fault.
FDD layer 216 can be configured to output a specific identification of the faulty component or cause of the fault (e.g., faulty IoT device or sensor) using detailed subsystem inputs available at IoT device integration layer 220. In other exemplary embodiments, FDD layer 216 is configured to provide “fault” events to integrated control layer 218 which executes control strategies and policies in response to the received fault events. According to some embodiments, FDD layer 216 (or a policy executed by an integrated control engine or business rules engine) may shut-down IoT systems, devices, and/or or components or direct control activities around faulty IoT systems, devices, and/or components to reduce waste, extend IoT device life, or to assure proper control response.
FDD layer 216 can be configured to store or access a variety of different system data stores (or data points for live data). FDD layer 216 may use some content of the data stores to identify faults at the IoT device or equipment level and other content to identify faults at component or subsystem levels. For example, the IoT devices 228 may generate temporal (i.e., time-series) data indicating the performance of IoTMS 200 and the various components thereof. The data generated by the IoT devices 228 can include measured or calculated values that exhibit statistical characteristics and provide information about how the corresponding system or IoT application process is performing in terms of error from its setpoint. These processes can be examined by FDD layer 216 to expose when the system begins to degrade in performance and alert a user to repair the fault before it becomes more severe.

Communications interface 304 can facilitate communications between IoTMS 300 and external applications (e.g., remote systems and applications 244) for allowing user control, monitoring, and adjustment to IoTMS 300. Communications interface 304 can also facilitate communications between IoTMS 300 and client devices 248.

The memory can include one or more devices (e.g., memory units, memory devices, storage devices, etc.) for storing data and/or computer code for completing and/or facilitating the various processes described in the present disclosure. Memory can include random access memory (RAM), read-only memory (ROM), hard drive storage, temporary storage, non-volatile memory, flash memory, optical memory, or any other suitable memory for storing software objects and/or computer instructions. Memory can include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described in the present disclosure. Memory can be communicably connected to the processor via the processing circuit and can include computer code for executing (e.g., by the processor) one or more processes described herein.
Still referring to
The data samples can include one or more attributes that describe or characterize the corresponding data points. For example, the data samples can include a name attribute defining a point name or ID (e.g., “B1F4R2.T-Z”), a device attribute indicating a type of device from which the data samples are received, a unit attribute defining a unit of measure associated with the data value (e.g., ° F., ° C., kPA, etc.), and/or any other attribute that describes the corresponding data point or provides contextual information regarding the data point. The types of attributes included in each data point can depend on the communications protocol used to send the data samples to Cloud IoT platform services 320. For example, data samples received via the ADX protocol or BACnet protocol can include a variety of descriptive attributes along with the data value, whereas data samples received via the Modbus protocol may include a lesser number of attributes (e.g., only the data value without any corresponding attributes).
In some embodiments, each data sample is received with a timestamp indicating a time at which the corresponding data value was measured or calculated. In other embodiments, data collector 312 adds timestamps to the data samples based on the times at which the data samples are received. Data collector 312 can generate raw timeseries data for each of the data points for which data samples are received. Each timeseries can include a series of data values for the same data point and a timestamp for each of the data values. For example, a timeseries for a data point provided by a temperature sensor can include a series of temperature values measured by the temperature sensor and the corresponding times at which the temperature values were measured. An example of a timeseries which can be generated by data collector 312 is as follows:
[<key, timestamp1, value1>, <key, timestamp2, value2>, <key, timestamp3, value3>] where key is an identifier of the source of the raw data samples (e.g., timeseries ID, sensor ID, etc.), timestampi identifies the time at which the ith sample was collected, and valuei indicates the value of the ith sample.
Data collector 312 can add timestamps to the data samples or modify existing timestamps such that each data sample includes a local timestamp. Each local timestamp indicates the local time at which the corresponding data sample was measured or collected and can include an offset relative to universal time. The local timestamp indicates the local time at the location the data point was measured at the time of measurement. The offset indicates the difference between the local time and a universal time (e.g., the time at the international date line). For example, a data sample collected in a time zone that is six hours behind universal time can include a local timestamp (e.g., Timestamp=2016-03-18T14:10:02) and an offset indicating that the local timestamp is six hours behind universal time (e.g., Offset=−6:00). The offset can be adjusted (e.g., +1:00 or −1:00) depending on whether the time zone is in daylight savings time when the data sample is measured or collected.
The combination of the local timestamp and the offset provides a unique timestamp across daylight saving time boundaries. This allows an application using the timeseries data to display the timeseries data in local time without first converting from universal time. The combination of the local timestamp and the offset also provides enough information to convert the local timestamp to universal time without needing to look up a schedule of when daylight savings time occurs. For example, the offset can be subtracted from the local timestamp to generate a universal time value that corresponds to the local timestamp without referencing an external database and without requiring any other information.
In some embodiments, data collector 312 organizes the raw timeseries data. Data collector 312 can identify a system or device associated with each of the data points. For example, data collector 312 can associate a data point with an IoT device, system, component, sensor, or any other type of system or device. In some embodiments, a data point entity may be created for the data point, in which case, the data collector 312 can associate the data point with the data point entity. In various embodiments, data collector uses the name of the data point, a range of values of the data point, statistical characteristics of the data point, or other attributes of the data point to identify a particular system, device, or data point entity associated with the data point. Data collector 312 can then determine how that system or device relates to the other systems or devices in the IoT environment from entity data. For example, data collector 312 can determine that the identified system or device is part of a larger system or serves a particular function within the larger system from the entity data. In some embodiments, data collector 312 uses or retrieves an entity graph (e.g., via the entity service 326) based on the entity data when organizing the timeseries data.
Data collector 312 can provide the raw timeseries data to the other Cloud IoT platform services 320 and/or store the raw timeseries data in storage 314. Storage 314 may be internal storage or external storage. For example, storage 314 can be internal storage with relation to Cloud IoT platform service 320 and/or IoTMS 300, and/or may include a remote database, cloud-based data hosting, or other remote data storage. Storage 314 can be configured to store the raw timeseries data obtained by data collector 312, the derived timeseries data generated by Cloud IoT platform services 320, and/or directed acyclic graphs (DAGs) used by Cloud IoT platform services 320 to process the timeseries data.

In some embodiments, timeseries service 328 aggregates predefined intervals of the raw timeseries data (e.g., quarter-hourly intervals, hourly intervals, daily intervals, monthly intervals, etc.) to generate new derived timeseries of the aggregated values. These derived timeseries can be referred to as “data rollups” since they are condensed versions of the raw timeseries data. The data rollups generated by timeseries service 328 provide an efficient mechanism for IoT applications 330 to query the timeseries data. For example, IoT applications 330 can construct visualizations of the timeseries data (e.g., charts, graphs, etc.) using the pre-aggregated data rollups instead of the raw timeseries data. This allows IoT applications 330 to simply retrieve and present the pre-aggregated data rollups without requiring IoT applications 330 to perform an aggregation in response to the query. Since the data rollups are pre-aggregated, IoT applications 330 can present the data rollups quickly and efficiently without requiring additional processing at query time to generate aggregated timeseries values.
In some embodiments, timeseries service 328 calculates virtual points based on the raw timeseries data and/or the derived timeseries data. Virtual points can be calculated by applying any of a variety of mathematical operations (e.g., addition, subtraction, multiplication, division, etc.) or functions (e.g., average value, maximum value, minimum value, thermodynamic functions, linear functions, nonlinear functions, etc.) to the actual data points represented by the timeseries data. For example, timeseries service 328 can calculate a virtual data point (pointID3) by adding two or more actual data points (pointID1 and pointID2) (e.g., pointID3=pointIDi+pointID2). As another example, timeseries service 328 can calculate an enthalpy data point (pointID4) based on a measured temperature data point (pointID5) and a measured pressure data point (pointID6) (e.g., pointID4=enthalpy(pointID5, pointID6)). The virtual data points can be stored as derived timeseries data.
IoT applications 330 can access and use the virtual data points in the same manner as the actual data points. IoT applications 330 do not need to know whether a data point is an actual data point or a virtual data point since both types of data points can be stored as derived timeseries data and can be handled in the same manner by IoT applications 330. In some embodiments, the derived timeseries are stored with attributes designating each data point as either a virtual data point or an actual data point. Such attributes allow IoT applications 330 to identify whether a given timeseries represents a virtual data point or an actual data point, even though both types of data points can be handled in the same manner by IoT applications 330.
In some embodiments, analytics service 324 analyzes the raw timeseries data and/or the derived timeseries data with the entity data to detect faults. Analytics service 324 can apply a set of fault detection rules based on the entity data to the timeseries data to determine whether a fault is detected at each interval of the timeseries. Fault detections can be stored as derived timeseries data. For example, analytics service 324 can generate a new fault detection timeseries with data values that indicate whether a fault was detected at each interval of the timeseries. The fault detection timeseries can be stored as derived timeseries data along with the raw timeseries data in storage 314.
Still referring to
IoT applications 330 can use the derived timeseries data and entity data to perform a variety data visualization, monitoring, and/or control activities. For example, resource management application 332 and monitoring and reporting application 334 can use the derived timeseries data and entity data to generate user interfaces (e.g., charts, graphs, etc.) that present the derived timeseries data and/or entity data to a user. In some embodiments, the user interfaces present the raw timeseries data and the derived data rollups in a single chart or graph. For example, a dropdown selector can be provided to allow a user to select the raw timeseries data or any of the data rollups for a given data point.
Enterprise control application 336 can use the derived timeseries data and/or entity data to perform various control activities. For example, enterprise control application 336 can use the derived timeseries data and/or entity data as input to a control algorithm (e.g., a state-based algorithm, an extremum seeking control (ESC) algorithm, a proportional-integral (PI) control algorithm, a proportional-integral-derivative (PID) control algorithm, a model predictive control (MPC) algorithm, a feedback control algorithm, etc.) to generate control signals for IoT devices 228. In some embodiments, IoT devices 228 use the control signals to operate other systems, devices, components, and/or sensors, which can affect the measured or calculated values of the data samples provided to IoTMS 300 and/or Cloud IoT platform services 320. Accordingly, enterprise control application 336 can use the derived timeseries data and/or entity data as feedback to control the systems and devices of the IoT devices 228.

In some embodiments, an object entity may be defined as having at least three types of attributes. For example, an object entity may have a static attribute, a dynamic attribute, and a behavioral attribute. The static attribute may include any unique identifier of the object entity or characteristic of the object entity that either does not change over time or changes infrequently (e.g., a device ID, a person's name or social security number, a place's address or room number, and the like). The dynamic attribute may include a property of the object entity that changes over time (e.g., location, age, measurement, data point, and the like). In some embodiments, the dynamic attribute of an object entity may be linked to a data entity. In this case, the dynamic attribute of the object entity may simply refer to a location (e.g., data/network address) or static attribute (e.g., identifier) of the linked data entity, which may store the data (e.g., the value or information) of the dynamic attribute. Accordingly, in some such embodiments, when a new data point is received for the object entity, only the linked data entity may be updated, while the object entity remains unchanged. Therefore, resources that would have been expended to update the object entity may be reduced.
However, the present disclosure is not limited thereto. For example, in some embodiments, there may also be some data that is updated (e.g., during predetermined intervals) in the dynamic attribute of the object entity itself. For example, the linked data entity may be configured to be updated each time a new data point is received, whereas the corresponding dynamic attribute of the object entity may be configured to be updated less often (e.g., at predetermined intervals less than the intervals during which the new data points are received). In some implementations, the dynamic attribute of the object entity may include both a link to the data entity and either a portion of the data from the data entity or data derived from the data of the data entity. For example, in an embodiment in which periodic odometer readings are received from a connected car, an object entity corresponding to the car could include the last odometer reading and a link to a data entity that stores a series of the last ten odometer readings received from the car.
The behavioral attribute may define a function of the object entity, for example, based on inputs, capabilities, and/or permissions. For example, behavioral attributes may define the types of inputs that the object entity is configured to accept, how the object entity is expected to respond under certain conditions, the types of functions that the object entity is capable of performing, and the like. As a non-limiting example, if the object entity represents a person, the behavioral attribute of the person may be his/her job title or job duties, user permissions to access certain systems, expected location or behavior given a time of day, tendencies or preferences based on connected activity data received by entity service 326 (e.g., social media activity), and the like. As another non-limiting example, if the object entity represents a device, the behavioral attributes may include the types of inputs that the device can receive, the types of outputs that the device can generate, the types of controls that the device is capable of, the types of software or versions that the device currently has, known responses of the device to certain types of input (e.g., behavior of the device defined by its programming), and the like.
In some embodiments, the data entity may be defined as having at least a static attribute and a dynamic attribute. The static attribute of the data entity may include a unique identifier or description of the data entity. For example, if the data entity is linked to a dynamic attribute of an object entity, the static attribute of the data entity may include an identifier that is used to link to the dynamic attribute of the object entity. In some embodiments, the dynamic attribute of the data entity represents the data for the dynamic attribute of the linked object entity. In some embodiments, the dynamic attribute of the data entity may represent some other data that is analyzed, inferred, calculated, or determined based on data from a plurality of data sources.
In some embodiments, the relational object may be defined as having at least a static attribute. The static attribute of the relational object may semantically define the type of relationship between two or more entities. For example, in a non-limiting embodiment, a relational object for a relationship that semantically defines that Entity A has a part of Entity B, or that Entity B is a part of Entity A may include:
hasPart{Entity A, Entity B}
where the static attribute hasPart defines what the relationship is of the listed entities, and the order of the listed entities or data field of the relational object specifies which entity is the part of the other (e.g., Entity A→hasPart→Entity B).
In various embodiments, the relational object is an object-oriented construct with predefined fields that define the relationship between two or more entities, regardless of the type of entities. For example, Cloud IoT platform service 320 can provide a rich set of pre-built entity models with standardized relational objects that can be used to describe how any two or more entities are semantically related, as well as how data is exchanged and/or processed between the entities. Accordingly, a global change to a definition or relationship of a relational object at the system level can be effected at the object level, without having to manually change the entity relationships for each object or entity individually. Further, in some embodiments, a global change at the system level can be propagated through to third-party applications integrated with Cloud IoT platform services 320 such that the global change can be implemented across all of the third-party applications without requiring manual implementation of the change in each disparate application.
For example, referring to
For example, an entity type (or object) “Activity Tracker” may be represented via the below schema:
where various attributes are static attributes (e.g., “Type,” “Model Number,” “Device Name,” etc.), dynamic attributes (e.g., “Location,” “Current Time,” etc.), or behavioral attributes (e.g., “Current Heart Rate,” “Daily Number of Steps,” etc.) for the object entity “Activity Tracker.” In a relational database, the object “Activity Tracker” is a table name, and the attributes represents column names.
An example of an object entity data model for a person named John Smith in a relational database may be represented by the below table:
where various attributes are static attributes (e.g., “First Name,” “Last Name,” etc.), dynamic attributes (e.g., “Age,” “Location,” etc.), or behavioral attributes (e.g., “Engineer”) for the object entity “John Smith.”
An example data entity for the data point “Daily Number of Steps” for the “Activity Tracker” owned by John Smith in a relational database may be represented by the below table:
where various attributes are static attributes (e.g., “Description” and “Device_Type”) and dynamic attributes (e.g., “Present-Value”).
While structuring the entities via entity type or object may help to define the data representation of the entities, these data models do not provide information on how the entities relate to each other. For example, an IoT application, controller, or platform may need data from a plurality of sources as well as information on how the sources relate to each other in order to provide a proper decision, action, or recommendation. Accordingly, in various embodiments, the entity data further includes the relational objects to semantically define the relationships between the entities, which may help to increase speeds in analyzing data, as well as provide ease of navigation and browsing.
For example, still referring to
For example, the entity graph 500 shows that a person named John (object entity) 504 isAKindOf (relational object) 506 User (class entity) 508. John 504 Owns (relational object) 510 the Activity Tracker (object entity) 502. The Activity Tracker 502 has a location attribute (dynamic attribute) 512 that isLinked (relational object) 514 to Geo 301-01 (data entity) 316, which isAKindOf (relational object) 518 an Address (class entity) 520. Accordingly, Geo 301-01 316 should have a data point corresponding to an address.
The Activity Tracker 502 further includes a “Daily Number of Steps” attribute (dynamic attribute) 522 that isLinked (relational object) 524 to AI 201-01 (data entity) 526. AI 201-01 526 isAKindOf (relational object) 528 Activity Object (class entity) 530. Thus, AI 201-01 526 should contain some sort of activity related data. AI 201-01 526 hasStorage (relational object) 532 at TS ID 1 (data entity) 534. AI 201-01 526 hasOperation (relational object) 536 of Daily Average 1 (data entity) 538, which isAKindOf (relational object) 540 Analytic Operator (class entity) 542. Accordingly, Daily Average 1 should hold some data that is the result of an analytic operation.
In this example, the data entity AI 201-01 526 may be represented by the following data model:
where “point” is an example of a data entity that may be created by Cloud IoT platform Services 320 to hold the value for the linked “Daily Number of Steps” 522 dynamic attribute of the Activity Tracker entity 502, and source is the sensor or device in the Activity Tracker device 502 that provides the data to the linked “Daily Number of Steps” 522 dynamic attribute.
The data entity TS Id 1 534 may be represented, for example, by the following data model:
where the data entity Daily Average 1 538 represents a specific analytic operator used to create the data entity for the average daily timeseries TS Id 1 534 based on the values of the corresponding data entity for point AI 201-01 526. The relational object hasOperation shows that the AI 201-01 data entity 526 is used as an input to the specific logic/math operation represented by Daily Average 1 538. TS Id 1 534 might also include an attribute that identifies the analytic operator Daily Average 1 538 as the source of the data samples in the timeseries.

In some embodiments, any two entities (or nodes) can be connected to each other via one or more relational objects that define different relationships between the two entities (or nodes). For example, still referring to
In this case, when the data entities associated with the activity tracker object entity 502 indicates that John is wearing the activity tracker (e.g., which may be determined from the daily number of steps attribute 522 or the location attribute 512), the relational object isWearing may be created between the object entity for John 510 and the object entity for activity tracker 502. On the other hand, when the data entities associated with the activity tracker object entity 502 indicates that John is not wearing the activity tracker (e.g., which may be determined when the daily number of steps attribute 522 for a current day is zero or the location attribute 512 shows a different location from a known location of John), the relational object isNotWearing can be created between the object entity for John 510 and the object entity for activity tracker 502. For example, the relational object isNotWearing can be created by modifying the relational object isWearing or deleting the relational object isWearing and creating the relational object isNotWearing. Thus, in some embodiments, the relational objects can be dynamically created, modified, or deleted as needed or desired.

Web service 402 can be configured to interact with web-based applications to send entity data and/or receive raw data (e.g., data samples, timeseries data, and the like). For example, web service 402 can provide an interface (e.g., API, UI/UX, and the like) to manage (e.g., register, create, edit, delete, and/or update) an entity (e.g., class entity, object entity, data entity, and/or the like) and the relational objects that define the relationships between the entities. In some embodiments, web service 402 provides entity data to web-based applications. For example, if one or more of applications 330 are web-based applications, web service 402 can provide entity data to the web-based applications. In some embodiments, web service 402 receives raw data samples and/or raw timeseries data including device information from a web-based data collector, or a web-based security service to identify authorized entities and to exchange secured messages. For example, if data collector 312 is a web-based application, web service 402 can receive the raw data samples and/or timeseries data including a device attribute indicating a type of device (e.g., IoT device) from which the data samples and/or timeseries data are received from data collector 312. In some embodiments, web service 402 may message security service 322 to request authorization information and/or permission information of a particular entity or device. In some embodiments, the entity service 326 processes and transforms the collected data to generate the entity data.
The registration service 404 can perform registration of devices and entities. For example, registration service 404 can communicate with IoT devices 228 and client devices 248 (e.g., via web service 402) to register each IoT device with Cloud IoT platform services 320. In some embodiments, registration service 404 registers a particular IoT device 228 with a specific user and/or a specific set of permissions and/or entitlements. For example, a user may register a device key and/or a device ID associated with the IoT device 228 via a web portal (e.g., web service 402). In some embodiments, the device ID and the device key may be unique to the IoT device 228. The device ID may be a unique number associated with the device such as a unique alphanumeric string, a serial number of IoT device 228, and/or any other static identifier. In various embodiments, IoT device 228 is provisioned by a manufacturer and/or any other entity. In various embodiments, the device key and/or device ID are saved to IoT device 228 based on whether IoT device 228 includes a trusted platform module (TPM). If the IoT device 228 includes a TPM, the IoT device 228 may store the device key and/or device ID according to the protocols of the TPM. If the IoT device 228 does not include a TPM, the IoT device 228 may store the device key and/or device ID in a file and/or file field which may be stored in a secure storage location. Further, in some embodiments, the device ID may be stored with BIOS software of the IoT device 228. For example, a serial number of BIOS software may become and/or may be updated with the device ID.
In various embodiments, the device key and/or the device ID are uploaded to registration service 404 (e.g., an IoT hub such as AZURE® IoT Hub). In some embodiments, registration service 404 is configured to store the device key and the device ID in secure permanent storage and/or may be stored by security service 322 (e.g., by a security API). In some embodiments, a manufacturer and/or any other individual may register the device key and the device ID with registration service 404 (e.g., via web service 402). In various embodiments, the device key and the device ID are linked to a particular profile associated with the IoT device 228 and/or a particular user profile (e.g., a particular user). In this regard, a device (e.g., IoT device 228) can be associated with a particular user. In various embodiments, the device key and the device ID make up the profile for IoT device 228. The profile may be registered as a device that has been manufactured and/or provisioned but has not yet been purchased by an end user.
In various embodiments, registration service 404 adds and/or updates a device in an IoT hub device registry. In various embodiments, registration service 404 may determine if the device is already registered, can set various authentication values (e.g., device ID, device key), and can update the IoT hub device registry. In a similar manner, registration service 404 can update a document database with the various device registration information.
In some embodiments, registration service 404 can be configured to create a virtual representation (e.g., “digital twins” or “shadow records”) of each IoT device in an IoT environment within Cloud IoT platform services 320. In some embodiments, the virtual device representations are smart entities that include attributes defining or characterizing the corresponding physical IoT devices and are associated to the corresponding physical IoT devices via relational objects defining the relationship of the IoT device and the smart entity representation thereof. In some embodiments, the virtual device representations maintain shadow copies of the IoT devices with versioning information so that Cloud entity service 326 can store not only the most recent update of an attribute (e.g., a dynamic attribute) associated with the IoT device, but records of previous states of the attributes (e.g., dynamic attributes) and/or entities. For example, the shadow record may be created as a type of data entity that is related to a linked data entity corresponding to the dynamic attribute of the object entity (e.g., IoT device). For example, the shadow entity may be associated with the linked data entity via a relational object (e.g., isLinked, hasStorage, hasOperation, and the like). In this case, the shadow entity may be used to determine additional analytics for the data point of the dynamic attribute. For example, the shadow entity may be used to determine an average value, and expected value, or an abnormal value of the data point from the dynamic attribute.
Management service 406 may create, modify, or update various attributes, data entities, and/or relational objects of the devices managed by Cloud IoT platform services 326 for each entity rather than per class or type of entity. This allows for separate processing/analytics for each individual entity rather than only to a class or type of entity. Some attributes (or data entities) may correspond to, for example, the most recent value of a data point provided to Cloud IoT platform services 326 via the raw data samples and/or timeseries data. For example, the “Daily Number of Steps” dynamic attribute of the “Activity Tracker” object entity 502 in the example discussed above may be the most recent value of a number of steps data point provided by the Activity Tracker device. Management service 406 can use the relational objects of the entity data for Activity Tracker to determine where to update the data of the attribute.
For example, Management service 406 may determine that a data entity (e.g., AI 201-01) is linked to the “Daily Number of Steps” dynamic attribute of Activity Tracker via an isLinked relational object. In this case, Management service 406 may automatically update the attribute data in the linked data entity. Further, if a linked data entity does not exist, Management service 406 can create a data entity (e.g., AI 201-01) and an instance of the isLinked relational object 524 to store and link the “Daily Number of Steps” dynamic attribute of Activity Tracker therein. Accordingly, processing/analytics for activity tracker 502 may be automated. As another example, a “most recent view” attribute (or linked data entity) of a webpage object entity may indicate the most recent time at which the webpage was viewed. Management service 406 can use the entity data from a related click tracking system object entity or web server object entity to determine when the most recent view occurred and can automatically update the “most recent view” attribute (or linked data entity) of the webpage entity accordingly.
Other data entities and/or attributes may be created and/or updated as a result of an analytic, transformation, calculation, or other processing operation based on the raw data and/or entity data. For example, Management service 406 can use the relational objects in entity data to identify a related access control device (e.g., a card reader, a keypad, etc.) at the entrance/exit of a building object entity. Management service 406 can use raw data received from the identified access control device to track the number of occupants entering and exiting the building object entity (e.g., via related card entities used by the occupants to enter and exit the building). Management service 406 can update a “number of occupants” attribute (or corresponding data entity) of the building object entity each time a person enters or exits the building using a related card object entity, such that the “number of occupants” attribute (or data entity) reflects the current number of occupants within the building (or related building object entity). As another example, a “total revenue” attribute associated with a product line object entity may be the summation of all the revenue generated from related point of sales entities. Management service 406 can use the raw data received from the related point of sales entities to determine when a sale of the product occurs, and can identify the amount of revenue generated by the sales. Management service 406 can then update the “total revenue” attribute (or related data entity) of the product line object entity by adding the most recent sales revenue from each of the related point of sales entities to the previous value of the attribute.
In some embodiments, management service 406 uses entity data and/or raw data from multiple different data sources to update the attributes (or corresponding data entities) of various object entities. For example, an object entity representing a person (e.g., a person's cellular device or other related object entity) may include a “risk” attribute that quantifies the person's level of risk attributable to various physical, environmental, or other conditions. Management service 406 can use relational objects of the person object entity to identify a related card device and/or a related card reader from a related building object entity (e.g., the building in which the person works) to determine the physical location of the person at any given time. Management service 406 can use weather data from a weather service in the region in which the building object entity is located to determine whether any severe weather is approaching the person's location. Similarly, management service 406 can use building data from related building entities of the building object entity to determine whether the building in which the person is located is experiencing any emergency conditions (e.g., fire, building lockdown, etc.) or environmental hazards (e.g., detected air contaminants, pollutants, extreme temperatures, etc.) that could increase the person's level of risk. Management service 406 can use these and other types of data as inputs to a risk function that calculates the value of the person object entity's “risk” attribute and can update the person object entity (or related device entity of the person) accordingly.
In some embodiments, management service 406 can be configured to synchronize configuration settings, parameters, and other device-specific information between the entities and Cloud IoT platform services 320. In some embodiments, the synchronization occurs asynchronously. Management service 406 can be configured to manage device properties dynamically. The device properties, configuration settings, parameters, and other device-specific information can be synchronized between the smart entities created by and stored within Cloud IoT platform services 320.
In some embodiments, management service 406 is configured to manage a manifest for each of the IoT devices. The manifest may include a set of relationships between the IoT devices and various entities. Further, the manifest may indicate a set of entitlements for the IoT devices and/or entitlements of the various entities and/or other entities. The set of entitlements may allow an IoT device and/or a user of the device to perform certain actions within the IoT environment (e.g., control, configure, monitor, and/or the like).

In some embodiments, transformation service 408 can provide entity matching, cleansing, and correlation so that a unified cleansed view of the entity data including the entity related information (e.g., relational objects) can be provided. Transformation service 408 can support semantic and syntactic relationship description in the form of standardized relational objects between the various entities. This may simplify machine learning because the relational objects themselves provide all the relationship description between the other entities. Accordingly, the rich set of pre-built entity models and standardized relational objects may provide for rapid application development and data analytics.

A computer program (also known as a program, software, software application, script, or code) may be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it may be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program may be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program may be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
The processes and logic flows described in this specification may be performed by one or more programmable processors executing one or more computer programs to perform actions by operating on input data and generating output. The processes and logic flows may also be performed by, and apparatus may also be implemented as, special purpose logic circuitry (e.g., an FPGA or an ASIC).
Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random access memory or both. The essential elements of a computer are a processor for performing actions in accordance with instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data (e.g., magnetic, magneto-optical disks, or optical disks). However, a computer need not have such devices. Moreover, a computer may be embedded in another device (e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), etc.). Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices (e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto-optical disks; and CD ROM and DVD-ROM disks). The processor and the memory may be supplemented by, or incorporated in, special purpose logic circuitry.
In various implementations, the steps and operations described herein may be performed on one processor or in a combination of two or more processors. For example, in some implementations, the various operations could be performed in a central server or set of central servers configured to receive data from one or more devices (e.g., edge computing devices/controllers) and perform the operations. In some implementations, the operations may be performed by one or more local controllers or computing devices (e.g., edge devices), such as controllers dedicated to and/or located within a particular building or portion of a building. In some implementations, the operations may be performed by a combination of one or more central or offsite computing devices/servers and one or more local controllers/computing devices. All such implementations are contemplated within the scope of the present disclosure. Further, unless otherwise indicated, when the present disclosure refers to one or more computer-readable storage media and/or one or more controllers, such computer-readable storage media and/or one or more controllers may be implemented as one or more central servers, one or more local controllers or computing devices (e.g., edge devices), any combination thereof, or any other combination of storage media and/or controllers regardless of the location of such devices.
To provide for interaction with a user, implementations of the subject matter described in this specification may be implemented on a computer having a display device (e.g., a CRT (cathode ray tube), LCD (liquid crystal display), OLED (organic light emitting diode), TFT (thin-film transistor), or other flexible configuration, or any other monitor for displaying information to the user and a keyboard, a pointing device, e.g., a mouse, trackball, etc., or a touch screen, touch pad, etc.) by which the user may provide input to the computer. Other kinds of devices may be used to provide for interaction with a user as well; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback), and input from the user may be received in any form, including acoustic, speech, or tactile input. In addition, a computer may interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user's client device in response to requests received from the web browser.
Implementations of the subject matter described in this disclosure may be implemented in a computing system that includes a back-end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front end component (e.g., a client computer) having a graphical user interface or a web browser through which a user may interact with an implementation of the subject matter described in this disclosure, or any combination of one or more such back end, middleware, or front end components. The components of the system may be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a LAN and a WAN, an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks).
The present disclosure may be embodied in various different forms, and should not be construed as being limited to only the illustrated embodiments herein. Rather, these embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the aspects and features of the present disclosure to those skilled in the art. Accordingly, processes, elements, and techniques that are not necessary to those having ordinary skill in the art for a complete understanding of the aspects and features of the present disclosure may not be described. Unless otherwise noted, like reference numerals denote like elements throughout the attached drawings and the written description, and thus, descriptions thereof may not be repeated. Further, features or aspects within each example embodiment should typically be considered as available for other similar features or aspects in other example embodiments.
It will be understood that, although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section described below could be termed a second element, component, region, layer or section, without departing from the spirit and scope of the present disclosure.
The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting of the present disclosure. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes,” and “including,” “has,” “have,” and “having,” when used in this specification, specify the presence of the stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
As used herein, the term “substantially,” “about,” and similar terms are used as terms of approximation and not as terms of degree, and are intended to account for the inherent variations in measured or calculated values that would be recognized by those of ordinary skill in the art. Further, the use of “may” when describing embodiments of the present disclosure refers to “one or more embodiments of the present disclosure.” As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively. Also, the term “exemplary” is intended to refer to an example or illustration.
