detailed description

In order to make the above objectives, features, and advantages of the application more obvious and understandable, the application will be further described in detail below in conjunction with the accompanying drawings and specific implementations.

1, it shows a flow chart of the steps of Embodiment 1 of a method for acquiring device data according to the present application.

In edge computing scenarios, it can be deployed in smart devices and computing nodes of different magnitudes, and connect devices with different protocols and different data formats through defined object models to provide safe, reliable, low-latency, low-cost, easy-scalable, and weakly dependent Local computing services. At the same time, the cloud server's big data, AI (Artificial Intelligence) learning, voice, video and other capabilities can be combined to create a cloud-side trinity computing system.

In edge computing, it mainly involves the device side, edge computing side and cloud server. Among them, developers can use the device to access SDK (Software Development Kit, software development kit), convert non-standard devices into standard object models, and access the gateway nearby to realize device management and control. The computing device running the application can be the edge computing terminal, that is, the edge gateway. When the device is connected to the gateway, the gateway can collect, transfer, store, analyze and report the device data to the cloud, and the gateway provides rule engines and functions The calculation engine facilitates scene orchestration and business expansion. The cloud server can combine the uploaded device data with cloud functions, such as big data, AI learning, etc., and realize more functions and applications through standard API (Application Programming Interface) interfaces.

As an example, in the edge computing scenario, the hardware capability of carrying services is usually weak, and the physical capability of a single gateway hardware is limited. In the case of a large amount of equipment (such as 10,000-level), a single gateway cannot be used for access. Existing problems include equipment wiring, insufficient single gateway interface or insufficient hardware processing capacity, etc., which requires the use of multiple gateways for access. However, in industrial production or building sites, field devices do not belong to the same gateway in terms of physical links. When the devices are related in business, the edge gateway is required to have the ability to implement cross-gateway device control and data sharing. However, each gateway can only access the sub-devices assigned to its own gateway, and cannot directly control or obtain information on sub-devices connected to other gateways.

In the embodiment of the present application, it is applied to an edge computing cluster, the edge computing cluster includes at least a first gateway and a second gateway, the first gateway includes a first proxy object, and the second gateway includes a second proxy object. Among them, both the first gateway and the second gateway can respectively communicate with multiple devices, so that each gateway can implement device data collection, circulation, storage, analysis, and reporting.

It should be noted that, in this application, the data interaction between two gateways is taken as an example for exemplification. It should be understood that the application is not limited to this.

In the specific implementation, through the ad hoc network of the edge gateway, the device data can be transferred between the gateways on demand. For example, when gateway A needs to access the information of sub-device one under other gateways, it only needs to send a request to the unique device identifier of sub-device one, just like the sub-device of this gateway, so that the edge gateway can be decentralized, Autonomous way to realize data sharing and device control between gateways. The method for acquiring the device data may include the following steps:

Step 101: The first proxy object sends a subscription request message for the first device to the second proxy object;

In the embodiment of this application, each gateway can run a proxy object and form an edge computing cluster between the proxy objects, so that it can subscribe to topics on any proxy object, and can also publish messages on any proxy object, and The edge computing cluster forwards the message to the correct proxy object on demand, so that the gateway can obtain the corresponding message or data.

In the specific implementation, by running a proxy object in each gateway, and forming an edge computing cluster between the objects, the originally isolated multiple edge gateways can be added to a logical grouping. In the logical grouping, each gateway can pass through the local The proxy object in the gateway subscribes to topics in other gateways, and can also publish messages to other gateways through the proxy object in this gateway. Logical grouping can ensure that messages are forwarded to the correct proxy object on demand, and then to the correct gateway.

In an example of the embodiment of the present application, each gateway can run an MQTT Broker instance, and an MQTT (Message Queuing Telemetry Transport) cluster is formed between Brokers (brokers), so that each gateway can pass through the Broker Realize data sharing and device control between gateways. Among them, the first proxy object and the second proxy object may be an external message broker in the gateway, which is responsible for data communication between the gateways. Specifically, the first proxy object and the second proxy object may be Mosquitto that implements the MQTT protocol. In the MQTT cluster, each gateway can communicate data through Mosquitto to realize device data sharing and cross-gateway device control.

In specific implementation, each gateway can subscribe to the internal MQTT Broker the device configuration of all sub-devices under the gateway, or publish the device data of the full quantum device of the gateway to the internal MQTT Broker, or subscribe to the internal MQTT Broker For the device data of interest, you can also process the received request message for subscribing to the device data of the gateway, and then respond.

Specifically, when the first gateway needs to obtain the device data of the first device under the second gateway, it can send a subscription request message for the first device to Mosquitto of the second gateway through Mosquitto to request the device data of the first device. When the second gateway receives the request, it can respond.

Step 102: The second proxy object obtains device data for the subscription request message, and sends the device data to the first proxy object.

In the embodiment of the present application, after the second gateway receives the subscription request message sent by the first proxy object through the second proxy object, it can obtain the device data for the subscription request message and send the device data to the first gateway The first proxy object.

In a specific implementation, each gateway can subscribe to the device data of interest through the internal MQTT Broker. When the first gateway sends a subscription request message to the second gateway through Mosquitto, after the Mosquitto of the second gateway receives the subscription request message, The full device data of the device corresponding to the subscription request message under the gateway can be obtained, and the device data can be published through Mosquitto, so that the first gateway can obtain the device data sent by the second gateway through Mosquitto, and realize an edge computing cluster based on each gateway. MQTT Broker can be used to share device data between gateways, ensuring that edge computing rules can be correlated across networks, achieving decentralization and edge autonomy, and improving edge computing capabilities.

In an example of an embodiment of the present application, as shown in FIG. 2, a schematic diagram of data flow in an embodiment of a method for obtaining device data of the present application is shown, where the dotted line is the transmission path of the subscription request message, and the actual The line is the transmission path of the device data. In the MQTT cluster, at least two gateways are included. Among them, the first gateway and the second gateway are in communication connection through the Mosquitto inside the gateway. Then, when the first gateway needs to obtain the device data of the sub-device ① under the second gateway, it can send a subscription request message for the sub-device ① to the second Mosquitto of the second gateway through the first Mosquitto, and when the second Mosquitto obtains the subscription request message Then, you can obtain the full amount of device data of the sub-device ①, and publish the device data, so that the first Mosquitto of the first gateway can receive the device data sent by the second Mosquitto, and realize the cluster based on MQTT, and each gateway can pass through MQTT Broker realizes device data sharing between gateways, ensuring that edge computing rules can be correlated across networks, achieving decentralization and edge autonomy, and improving edge computing capabilities.

In this embodiment of the application, it is applied to an edge computing cluster, the edge computing cluster includes at least a first gateway and a second gateway, the first gateway includes a first proxy object, and the second gateway includes a second proxy object, The second gateway communicates with at least one first device, and the first gateway sends a subscription request message for the first device through the first proxy object to the second gateway, and then the second gateway uses the first proxy object. Second, the proxy object obtains the device data for the subscription request message, and sends the device data to the first gateway, so that based on the edge computing cluster, each gateway can realize data sharing between the gateways through the proxy object, It is ensured that the edge computing rules can be linked across networks, realize decentralization and edge autonomy, and improve the ability of edge computing.

3, there is shown a flow chart of the second embodiment of a method for acquiring device data of the present application, which is applied to an edge computing cluster. The edge computing cluster includes at least a first gateway and a second gateway. The gateway includes a first proxy object, and the second gateway includes a second proxy object. The second gateway can communicate with at least one first device. The method can specifically include the following steps:

Step 301: The first operation agent object obtains a message route sent by the cloud server, and determines a subscription request message corresponding to the message route;

In the embodiment of the present application, when centralized collection of data is required, the cloud server can issue a data collection task to one of the gateways, using the gateway as an intermediate gateway, and the gateway can obtain the data of sub-devices under other gateways, and pass The intermediate gateway uploads all data to the cloud server, thereby realizing centralized data collection. Compared with equipment collection through each gateway, the data collection process is simplified and the data collection efficiency is improved.

In a specific implementation, each gateway can communicate with the cloud server, and the gateway can also include an operation proxy object that communicates with the cloud server. The operation proxy object can send local operation requests to the device operations under the gateway, and can also forward External device operation request, and other data forwarding, such as the forwarding of response messages, device data, etc.

Specifically, in an edge computing cluster, each gateway can subscribe to the device data of sub-devices of other gateways through the proxy object of the gateway, and the cloud server that communicates with each gateway can use a gateway in the edge computing cluster as an intermediate gateway. Centralized acquisition of data is performed through the intermediate gateway. When the first gateway is an intermediate gateway, the first operation proxy object in the first gateway can obtain the message route sent by the cloud server, and determine the subscription request message corresponding to the message route.

Among them, message routing can dynamically plan the transmission path of the message through routing rules, so that the message is transmitted from the message source to the target node according to the filtering conditions. The cloud server can determine the transmission path of the device data that needs to be obtained by configuring the message routing. For example, to obtain the device data of the gateway A neutron device 1, the gateway C neutron device two, and the gateway D neutron device three, you can configure the message routing to include : Intermediate gateway-gateway A-intermediate gateway, intermediate gateway-gateway B-intermediate gateway, and intermediate gateway-gateway B-intermediate gateway, etc., so that each gateway can transmit data according to the message route, simplifying the data transmission process and improving Improve the efficiency of data transmission.

In an example of the embodiment of the present application, the operation proxy object may include a message broker within the gateway, such as Message-Router, which is responsible for data communication within the gateway. In addition, the operation proxy object may also include a network correlation module, which acts as a data forwarding intermediary between the external message proxy object Mosquitto and the internal message proxy object Message-Router, which can convert the message sent by the Message-Router into a message based on the MQTT protocol. , And send it to Mosquitto, so that Mosquitto will forward the converted message in the MQTT cluster. It can also convert the message based on the MQTT protocol into a data format readable by the Message-Router and send it to the Message-Router. Specifically, the network linkage module may be Gw-Linkage, which is responsible for data forwarding between Mosquitto and Message-Router.

In a specific implementation, the gateway may also include a cloud proxy object communicatively connected with the cloud server, and the operation proxy object may also include a task scheduling module communicatively connected with the Message-Router. Among them, the cloud proxy object can be used as the data communication intermediary between the cloud server and the gateway, responsible for the data communication between the cloud and the edge computing terminal, and the task scheduling module can be responsible for the allocation of scene linkage tasks, such as when the cloud needs to obtain When the device data of each sub-device under multiple gateways is used, the task scheduling module can analyze the tasks issued by the cloud, determine the corresponding gateway and the corresponding sub-device, and perform corresponding operations.

Specifically, when the cloud needs to collect device data from the sub-devices of other gateways through one of the gateways, the corresponding message route can be issued to the gateway so that the gateway can obtain the information of the sub-devices of other gateways through the message route. Device data.

In an example of the embodiment of the present application, the cloud proxy object of the first gateway can obtain the message route issued by the cloud, and send the message route to the task scheduling module, and the task scheduling module parses the message route to determine The corresponding device data acquisition task, and the task is delivered to the Message-Router. After the Message-Router receives the task issued by the task scheduling module, it can generate the corresponding subscription request message. If the device data acquisition task includes acquiring the device data of the sub-device ① and the sub-device ② under the second gateway, the Message-Router can Generate the first subscription request message for the child device ① and the second subscription request message for the child device ②, and send the first subscription request message and the second subscription request message to Gw-Linkage, so that Gw-Linkage can transfer the first subscription request message to Gw-Linkage. The first subscription request message and the second subscription request message are converted into messages based on the MQTT protocol, so that the gateway can receive and process the message routing configured in the cloud.

Step 302: The first proxy object sends the subscription request message sent by the first operation proxy object to the second proxy object;

In a specific implementation, the first operation proxy object of the first gateway may send the subscription request message to the first proxy object, and the first proxy object sends the subscription request message to the second proxy object of the second gateway.

In an example of the embodiment of the present application, the Message-Router of the first gateway sends a subscription request message to Gw-Linkage, and Gw-Linkage can convert the subscription request message to a message based on the MQTT protocol, and send the MQTT message to Mosquitto, the Mosquitto of the first gateway sends the MQTT message to the Mosquitto of the second gateway to implement data communication between the gateways.

Step 303: The second operation proxy object sends the subscription request message sent by the second proxy object to the first device;

In a specific implementation, after the second proxy object of the second gateway receives the subscription request message sent by the first proxy object of the first gateway, the subscription request message can be sent to the second operation proxy object, and the second operation proxy The object sends the subscription request message to the first device.

In an example of the embodiment of the present application, Mosquitto of the second gateway can forward the message based on the MQTT protocol to Gw-Linkage, and Gw-Linkage will format the MQTT message to obtain the first The subscription request message of the device.

Step 304: The second operation proxy object obtains the device data for the subscription request message sent by the first device, and sends the device data to the second proxy object;

In a specific implementation, after sending the subscription request message to the first device, the second operation proxy object of the second gateway can receive the device data corresponding to the subscription request message reported by the first device, and send the device data to The second proxy object, so that the second proxy object sends the device data to the first gateway.

In an example of the embodiment of the present application, the Gw-Linkage of the second gateway can send the subscription request message to the Message-Router, and the Message-Router sends the subscription request message to the first device, and obtains the first device The sent device data for the subscription request message. Then Message-Router can send the device data to Gw-Linkage, and Gw-Linkage converts the device data into data based on the MQTT protocol.

Step 305: The second proxy object sends the device data to the first proxy object;

In a specific implementation, the second proxy object of the second gateway can send the device data sent by the second operation proxy object to the first gateway located in the same edge computing cluster, so that the first gateway can receive it through the first proxy object The device data.

In an example of the embodiment of the present application, after Mosquitto of the second gateway forwards the device data sent by Gw-Linkage to Mosquitto of the first gateway, Mosquitto of the first gateway can convert the data based on the MQTT protocol into Message- Router can read data and send the converted device data to the Message-Router of the first gateway.

Step 306: The first operation proxy object sends the device data sent by the first proxy object to the application.

In the embodiment of the present application, the gateway can also run an application program, which can implement local definition, development, testing, and debugging of a serverless application of the gateway, and upload device data to the cloud.

In a specific implementation, the first operation proxy object of the first gateway can send the device data sent by the first proxy object to the application, and the application processes the device data, such as controlling the corresponding device according to the device data, or The device data is reported to the cloud.

In an example of the embodiment of the present application, after the Gw-Linkage of the first gateway sends the device data to the Message-Router, the Message-Router can send the device data to the application to complete the collection of the device data, so that the cloud By sending the device data collection task to the first gateway, the first gateway acts as an intermediate gateway to collect device data from multiple other gateways. On the one hand, it simplifies the data collection process and improves the efficiency of data collection. On the one hand, in the device linkage scenario, multiple gateways can be taken as a whole and controlled by the cloud, which improves the linkage capability of edge computing.

It should be noted that the embodiment of the present application takes the first gateway as an example for illustrative description. It can be understood that after multiple gateways are networked to form an MQTT cluster, each gateway can share information about sub-devices and applications It can run on any gateway in the MQTT cluster. In addition, in addition to running applications, the gateway can also run IFTTT (If this then that) rules, so as to make full use of the computing power of the edge computing cluster and improve the application capabilities of edge computing.

In an example of an embodiment of the present application, as shown in FIG. 4, a schematic diagram of data flow in the second embodiment of a method for obtaining device data of the present application is shown. In an edge computing cluster, multiple gateways are included, and each A proxy object runs in each gateway, and each gateway performs data interaction through the proxy object. Wherein, when the application in the first gateway needs to subscribe to the device data of the sub-device ① in the second gateway, the first gateway can send the subscription request message to the first operation proxy object through the application, and then the first operation proxy object The subscription request message is sent to the first proxy object, and then the first proxy object sends the subscription request message to the second gateway.

After the second gateway receives the subscription request message through the second proxy object, it can send the subscription request message to the second operation proxy object, and the second operation proxy object sends the subscription request message to the sub-device ①, and then obtains the sub-device. The device data reported by the device ① is transmitted to the application program of the first gateway according to the predetermined transmission path, so that based on the edge computing cluster, each gateway can realize data sharing between the gateways through proxy objects, ensuring In this way, edge computing rules can be correlated across networks, achieving decentralization and edge autonomy, and improving edge computing capabilities.

It should be noted that, in the embodiment of the present application, the data interaction between the gateway and the gateway in the edge computing cluster is taken as an example for illustrative description. It is understandable that, in addition to the data interaction between the gateway and the gateway in the edge computing cluster, The data link for data collection can also include the data link between the cloud and the gateway for data collection.

Specifically, a hybrid mode can be used for data interaction, and different data links can be used for device data acquisition according to different data acquisition speeds. For example, the speed of acquiring device data through the data link between the cloud and the gateway is faster than that through the gateway and the gateway. If the data link is fast, the device data can be obtained through the data link between the cloud and the gateway; otherwise, the device data can be obtained through the data link between the gateway and the gateway in the edge computing cluster. The application is not restricted.

In another example of the embodiment of the present application, as shown in FIG. 5, a schematic diagram of data flow in the second embodiment of a method for acquiring device data of the present application is shown, where the solid line is the transmission path of the configuration information, The dashed line is the transmission path of the response message. In the MQTT cluster, it includes at least a first gateway and a second gateway. The first gateway and the second gateway respectively include the external message proxy object Mosquitto, the network linkage module Gw-Linkage, and the internal messages of the gateway. The proxy object Message-Router, the task scheduling module Task-Dispatcher, and the cloud proxy object Cloud-Proxy, etc., and the gateway can also run applications. Then, the cloud can configure the message routing and deliver the configured message routing to the first gateway, so that the first gateway can process the message routing and obtain the corresponding device data.

Specifically, after the Cloud-Proxy of the first gateway receives the message route issued by the cloud, it can send the message route to the Task-Dispatcher, and then the Task-Dispatcher can analyze the message route to determine the target device's data to be collected. Unique device identification, and send the device identification to the Message-Router of the first gateway, and the Message-Router generates a subscription request message for the target device, such as a subscription request message for the sub-device ① of the second gateway, and then the subscription The request message is sent to Gw-Linkage, and Gw-Linkage can convert the subscription request message into a message based on the MQTT protocol and send it to Mosquitto. Mosquitto of the first gateway sends the subscription request message to the second gateway located in the same MQTT cluster. .

When the Mosquitto of the second gateway receives the subscription request message sent by the first gateway, it can send the subscription request message to Gw-Linkage, and Gw-Linkage can convert the message based on the MQTT protocol into a data format readable by Message-Router , And send the converted subscription request message to the Message-Router, and the Message-Router sends the subscription request message to the sub-device ①, so that the sub-device ① can report the device data to the Message-Router, and the Message-Router can The entire data is forwarded to Gw-Linkage, and Gw-Linkage sends the device data to Mosquitto, so that Mosquitto of the second gateway can send the device data to the first gateway in the same MQTT cluster.

When the Mosquitto of the first gateway receives the device data sent by the second gateway, it can transmit the device data to the application through the following transmission paths: Mosquitto to Gw-Linkage, Gw-Linkage to Message-Router, and then from Message-Router To the application program, so as to complete the device data collection of the second gateway sub-device ①.

In another example of the embodiment of the present application, in the building construction scenario, the applications in gateways A and B are responsible for the preprocessing of the messages reported by the sensors under the gateway, and the application in gateway C subscribes to gateways A and B. The device data of the sensor. Among them, the sensor corresponding to gateway A is a temperature sensor, and the sensor corresponding to gateway B is a humidity sensor. Then the application in gateway A can count the average temperature every 5 minutes, and the application in gateway B can count the average humidity every 5 minutes, and then gateways A and B can publish the processed temperature and humidity data to gateway C. The application performs further analysis to decide whether to change the configuration of the central air-conditioning system in the building or upload the temperature and humidity data to the cloud.

It should be noted that, in the embodiment of the present application, the device data collection performed by the first gateway on one sub-device in the second gateway is taken as an example for illustration. It is understandable that the gateway can perform multiple sub-devices under multiple gateways. At the same time, device data collection is performed, so that the cloud sends device data collection tasks to a certain gateway, and the gateway acts as an intermediate gateway to collect device data from multiple other gateways. On the one hand, it simplifies the data collection process and improves This improves the efficiency of data collection. On the other hand, in the device linkage scenario, multiple gateways can be taken as a whole and controlled by the cloud, which improves the linkage capability of edge computing.

Among them, the first proxy object and the second proxy object may be an external message broker in the gateway, which is responsible for data communication between the gateways. Specifically, the first proxy object and the second proxy object may be Mosquitto that implements the MQTT protocol. In the MQTT cluster, each gateway can communicate data through Mosquitto to realize device data sharing and cross-gateway device control.

Specifically, when the first gateway needs to set the device attributes of the first device located in the second gateway, the configuration information used to configure the attributes of the first device can be sent to the second gateway through Mosquitto in the first gateway. Mosquitto, so that when the second gateway receives the configuration information, it can configure the attributes of the first device.

Step 602: The second proxy object sends a response message sent by the first device to the first proxy object, where the response message is a message for the first device to complete attribute configuration according to the configuration information .

In a specific implementation, after Mosquitto of the second gateway receives the configuration information sent by the first gateway, Mosquitto can send the configuration information to the corresponding device, so that when the device receives the configuration information, it can perform attributes based on the configuration information Configuration. After the configuration is completed, the device can generate a response message for the configuration information and send the response message to Mosquitto. Mosquitto sends the response message to the first gateway to inform the first gateway that the device has been configured. In an edge computing cluster, each gateway can implement device control between gateways through proxy objects, ensuring that edge computing rules can be associated across networks, achieving decentralization and edge autonomy, and improving the linkage capability of edge computing.

In an example of an embodiment of the present application, as shown in FIG. 7, a schematic diagram of data flow in Embodiment 1 of a device configuration method of the present application is shown, where the dotted line is the transmission path of the configuration information, and the solid line is The transmission path of the response message includes at least two gateways in the MQTT cluster, where the first gateway and the second gateway communicate through the Mosquitto inside the gateway. Then when the first gateway needs to control the sub-device ① of the second gateway, the configuration information for the sub-device ① can be sent to the second Mosquitto of the second gateway through the first Mosquitto. After the second Mosquitto obtains the configuration information, it can Send the configuration information to the sub-device ①, and the sub-device ① configures the attribute value according to the configuration information. After the configuration is completed, it can generate a response message and send the response message to Mosquitto. Then the Mosquitto of the second gateway can use the The response message is sent to the Mosquitto of the first gateway, which is based on MQTT cluster. Each gateway can realize device control between gateways through MQTT Broker, which ensures that edge computing rules can be correlated across networks to achieve decentralization, edge autonomy, and improve The ability of edge computing.

In this embodiment of the application, it is applied to an edge computing cluster, the edge computing cluster includes at least a first gateway and a second gateway, the first gateway includes a first proxy object, and the second gateway includes a second proxy object, The second gateway communicates with at least one first device, and the configuration information sent by the first gateway through the first proxy object is used to configure the configuration information of the first device under the second gateway to the second gateway, and then to the second gateway. The gateway sends the response message sent by the first device to the first gateway through the second proxy object, where the response message is a message that the first device completes the attribute configuration according to the configuration information, so that based on the edge computing cluster, each gateway can pass through The proxy object implements device control between gateways, ensuring that edge computing rules can be associated across networks, achieving decentralization and edge autonomy, and improving the linkage capability of edge computing.

Referring to Figure 8, there is shown a flow chart of the second embodiment of a device configuration method of the present application. The method is applied to an edge computing cluster. The edge computing cluster includes at least a first gateway and a second gateway. The first gateway includes a first proxy object, the second gateway includes a second proxy object, and the second gateway communicates with at least one first device. The method may specifically include the following steps:

Step 801: The first operation proxy object sends the configuration information sent by the application program to the first proxy object;

Then, when the application in the first gateway wants to control the first device in the second gateway, it can generate configuration information for configuring the first device, and send the configuration information to the first network association module, The first network association module sends the configuration information to the first proxy object.

In an example of the embodiment of the present application, after the application in the first gateway generates configuration information for configuring the first device in the second gateway, the configuration information can be sent to Gw-Linkage, Gw-Linkage The configuration information can be converted into information based on the MQTT protocol, and then the converted configuration information can be sent to Mosquitto.

Step 802: The first proxy object sends the configuration information to the second proxy object;

In a specific implementation, Mosquitto of the first gateway can send configuration information to Mosquitto of the second gateway.

Step 803: The second operation proxy object sends the configuration information sent by the second proxy object to the first device;

In a specific implementation, the second operation proxy object in the second gateway may send the configuration information sent by the second proxy object to the first device.

In an example of the embodiment of the present application, the Gw-Linkage of the second gateway can convert the configuration information based on the MQTT protocol into configuration information readable by the first device, and send the converted configuration information to the first device, After receiving the configuration information, the first device can set the attribute value according to the configuration information, generate a response message, and then send the response message to Gw-Linkage.

Step 804: The second proxy object sends the response message sent by the second operation proxy object to the first proxy object;

In a specific implementation, the second operation agent object in the second gateway may receive the response message sent by the first device, and the response message may be a message generated after the first device configures the attribute value according to the configuration information. Then the second proxy object can send the response message to the first proxy object in the first gateway.

Step 805: The first operation proxy object sends the response message sent by the first proxy object to the application.

In a specific implementation, the first operation proxy object of the first gateway can send the response message sent by the first proxy object to the application program, thereby notifying the application program that the first device in the second gateway has performed attributes according to the configuration information. Value configuration.

Specifically, after Mosquitto of the first gateway receives the response message, it can send the response message to Gw-Linkage, and Gw-Linkage converts the response message based on the MQTT protocol into a data format readable by the application, and converts the response message The subsequent response message is sent to the application to inform the application that the device in the second gateway has been configured. Based on the edge computing cluster, each gateway can implement device control between the gateways through proxy objects, ensuring the edge Computing rules can be linked across networks to achieve decentralization and edge autonomy, which improves the linkage capability of edge computing.

In an example of an embodiment of the present application, as shown in FIG. 4, a schematic diagram of data flow in the second embodiment of a device configuration method of the present application is shown. In an edge computing cluster, there are multiple gateways, each A proxy object runs in the gateway, and each gateway performs data interaction through the proxy object. Wherein, when the application in the first gateway needs to set the device attribute value of the sub-device ① in the second gateway, the first gateway can send the configuration information to the first operation proxy object through the application, and then the first operation proxy object The configuration information is sent to the first proxy object, and then the first proxy object sends the configuration information to the second gateway.

After the second gateway receives the configuration information through the second proxy object, it can send the configuration information to the second operation proxy object, and the second operation proxy object sends the configuration information to the sub-device ①, and then the sub-device ① The configuration information sets the attribute value, and sends a response message to the second operation agent object, and then transmits the response message to the application of the first gateway according to the predetermined transmission path, so that based on the edge computing cluster, each gateway can Implementing device control between gateways through proxy objects ensures that edge computing rules can be correlated across networks, achieving decentralization and edge autonomy, and improving edge computing capabilities.

In an example of the embodiment of the present application, as shown in FIG. 9, a schematic diagram of data flow in the second embodiment of a device configuration method of the present application is shown, where the dashed line is the transmission path of the configuration information, and the solid line is The transmission path of the response message, in the MQTT cluster, includes at least a first gateway and a second gateway. The first gateway and the second gateway may respectively include the external message proxy object Mosquitto, the network correlation module Gw-Linkage, and the message proxy inside the gateway. Object Message-Router, task scheduling module Task-Dispatcher and cloud proxy object Cloud-Proxy, etc., and applications can also be run in the gateway.

When the application in the first gateway needs to set the attribute value of the sub-device ① in the second gateway, the application can generate configuration information for setting the sub-device ①, and then send the configuration information to Gw-Linkage , Gw-Linkage converts the configuration information into configuration information based on the MQTT protocol, and sends the converted configuration information to Mosquitto, and Mosquitto sends the configuration information to the second gateway.

After the Mosquitto in the second gateway receives the configuration information, it can send the configuration information to Gw-Linkage, and Gw-Linkage converts the configuration information based on the MQTT protocol into the readable configuration information of the sub-device, and the configuration information Send to the sub-device①, then the sub-device① can configure the attribute value according to the configuration information. After the configuration is completed, it can generate a response message and send the response message to Gw-Linkage, and Gw-Linkage converts the response message It is a message based on the MQTT protocol, and sends the converted message to Mosquitto, and then Mosquitto sends the response message to the first gateway.

After Mosquitto in the first gateway receives the response message, it can transmit the response message to the application according to the following transmission path: Mosquitto to Gw-Linkage, and Gw-Linkage to the application, thereby completing cross-gateway device control.

In another example of the embodiment of the present application, in industrial production, the application programs in gateways A, B, C, and D are respectively responsible for the operation control of the sub-devices under the gateway, and each gateway forms an MQTT cluster. In the device linkage scenario, all sub-devices under gateways A, B, C, and D can be linked through any one of gateways A, B, C, and D, so as to complete cross-gateway and multi-device linkage. Improved the linkage capability of edge computing.

As shown in Figure 10, it shows a schematic diagram of the data flow in the second embodiment of a device control method of the present application. In industrial production, gateway A and gateway B respectively form edge computing clusters through proxy objects under the gateway, and The application programs of gateway A and gateway B are respectively responsible for the operation control of the sub-devices under the gateway. In the device linkage scenario, the cluster can be controlled by the application in the external device, such as the sub-devices dev_A1 and dev_A2 under the gateway A. , The sub-devices dev_B1 and dev_B2 under the gateway B carry out linkage control.

Specifically, gateway B can be used as an intermediate gateway, and external applications can subscribe device data or device operation requests to gateway B, so that gateway B can send to other gateways (gateway A) in the cluster through the proxy object in this gateway. Subscribe to device data request messages or device operation requests, so that one gateway in the cluster can be used as an intermediate gateway to obtain the device data of the sub-devices under each gateway, and send device operation requests to each, so that the edge computing cluster can be used as a whole , Provide services to the outside world, and realize the edge computing cluster based. A gateway can be used to obtain data or equipment control for each gateway in the cluster, which simplifies the data acquisition process and the equipment operation process, and greatly improves the work efficiency.

In addition, in addition to using gateway B as an intermediate gateway to control the sub-devices in gateway A, you can also directly control the sub-devices under gateway A and/or gateway B through the cloud. For example, the cloud can control the sub-devices in gateway A and/or gateway B. The sub-device dev_A1 under gateway A and dev_B2 under gateway B send device operation requests to control the sub-devices dev_A1 and dev_B2, so that in the edge computing cluster, not only can the sub-devices be directly operated and controlled through the cloud, but also A gateway in the edge computing cluster is used as an intermediate gateway to perform operation control on other gateways or sub-devices under this gateway, which enriches the device control methods of edge computing scenarios.

It should be noted that, in the embodiment of the present application, the first gateway controls a sub-device in the second gateway as an example for exemplification. It is understandable that the gateway can control multiple different gateways at the same time. The sub-devices are controlled at the same time, so that based on the edge computing cluster, each gateway can realize the device control between the gateways through the proxy object, which ensures that the edge computing rules can be correlated across the network, realizes decentralization, edge autonomy, and improves edge computing The linkage ability.

It should be noted that, in the embodiments of the present application, the acquisition of device data and the configuration of the device are taken as examples for description respectively. It is understandable that the two can be combined with each other. For example, in a building construction scenario, applications in gateways A and B are responsible for the preprocessing of messages reported by sensors under this gateway, while applications in gateway C subscribe to the device data in gateways A and B. Among them, the sensor corresponding to gateway A is a temperature sensor, and the sensor corresponding to gateway B is a humidity sensor. Then the application in gateway A can count the average temperature every 5 minutes, and the application in gateway B can count the average humidity every 5 minutes, and then gateways A and B can publish the processed temperature and humidity data to gateway C. The application program performs further analysis to determine whether to change the configuration of the central air-conditioning system in the building. When it needs to be changed, the gateway C can send the configuration information of the central air-conditioning system to the gateway D, and the gateway D transmits the configuration information to the central air-conditioning system to realize the attribute value setting of the central air-conditioning system.

It should be noted that for the method embodiments, for the sake of simple description, they are all expressed as a series of action combinations, but those skilled in the art should know that the embodiments of the present application are not limited by the described sequence of actions, because According to the embodiments of the present application, certain steps may be performed in other order or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present application.

Referring to FIG. 11, a structural block diagram of an embodiment of an edge computing cluster of the present application is shown.

As an example, in the edge computing scenario, the hardware capability of carrying services is usually weak, and the physical capability of a single gateway hardware is limited. In the case of a large amount of equipment (such as 10,000-level), a single gateway cannot be used for access. Existing problems include equipment wiring, insufficient single gateway interface or insufficient hardware processing capacity, etc., which requires the use of multiple gateways for access. However, in industrial production or building sites, field devices do not belong to the same gateway in terms of physical links. When the devices are related in business, the edge gateway is required to have the ability to implement cross-gateway device control and data sharing. However, each gateway can only access the sub-devices assigned to its own gateway, and cannot directly control or obtain information on sub-devices connected to other gateways. Therefore, the embodiment of the present application proposes an edge computing cluster, which can realize cross-network correlation between different gateways, and realize device data sharing and device control between gateways.

In the embodiment of the present application, the edge computing cluster may include multiple gateways, each gateway may be provided with a proxy object, and each gateway may perform data interaction through the proxy object.

In an example of the embodiment of the present application, multiple edge gateways can be networked, and each edge gateway runs an MQTT Broker instance, so that the edge gateways are networked to form an edge computing cluster. Realize the collection, circulation, storage, analysis, and reporting of device data between various gateways.

Specifically, the edge gateway may include a proxy object, and multiple different edge gateways can form an MQTT cluster through the proxy object. In the MQTT cluster, each gateway can realize the transfer of device data between the gateways on demand.

In the specific implementation, the configuration items required for the networking of the edge computing cluster include: gateway identification, gateway IP address, and shared key. Each edge gateway corresponds to an object of this structure, thus forming a Json array. The data transmission link is connected to each gateway, and the data transmission link is encrypted, thereby completing the networking of the edge computing cluster. Among them, the shared key is used for identity authentication and data transmission link encryption between gateways, and the pre-shared key TLS-PSK can be used for identity authentication and encryption, thereby taking into account security and flexibility.

Specifically, after different edge gateways are assembled into an edge computing cluster, different gateways in the edge computing cluster can mutually access sub-devices under other gateways to obtain corresponding device data, or for sub-devices under other gateways. Access and control. However, other gateways located outside the edge computing cluster cannot access the gateway in the cluster through the edge computing cluster, nor can they access the sub-devices under the gateway.

In addition, for sub-devices located in the same edge computing cluster, it can include a first sub-device and a second sub-device. The first sub-device can be a device that can be accessed through a data link, and the second sub-device can To encrypt the device, the device data on the second sub-device is encrypted data, and access to the device data on the second sub-device requires the access permission of the second sub-device to access it. If gateway A and gateway B are located in the same edge computing cluster, where the sub-device ① under gateway A is the first sub-device and sub-device ② is the second sub-device, then gateway B can pair the sub-devices through the data link in the cluster ①Access to obtain the device data of the sub-device ① or control the sub-device ①; and for the sub-device ②, the access permission of the sub-device ② is required to obtain the device data of the sub-device ② or control the sub-device ②, thus For encryption devices in the same edge computing cluster, the access rights of the encryption devices need to be obtained before data acquisition or device control can be performed, which can effectively ensure the data security of the devices in the same edge computing cluster and the security of device control.

It ensures that the edge computing rules can be correlated across networks, realize decentralization and edge autonomy, and improve the linkage capability of edge computing.

In the embodiment of the present application, the gateway may further include a cloud proxy object communicatively connected with the cloud server, and the operation proxy object may further include a task scheduling module communicatively connected with the Message-Router. Among them, the cloud proxy object can be used as the data communication intermediary between the cloud server and the gateway, responsible for the data communication between the cloud and the edge computing terminal, and the task scheduling module can be responsible for the allocation of scene linkage tasks, such as when the cloud needs to obtain When the device data of each sub-device under multiple gateways is used, the task scheduling module can analyze the tasks issued by the cloud, determine the corresponding gateway and the corresponding sub-device, and perform corresponding operations.

In a specific implementation, the cloud proxy object can be responsible for the communication between the edge gateway and the cloud server, the cloud can deliver data to the edge gateway, and the edge gateway can also report data to the cloud. In addition, in an edge computing cluster, since device data can be shared among multiple gateways, device data may be reported to the cloud from other gateways. Therefore, in order to avoid subscribed device data from being reported to the cloud from this gateway, the device data may be reported to the cloud. For repeated uploads of data, the cloud proxy object can monitor the device data uploaded by the gateway. When the device data is monitored as the device data of the sub-device under this gateway, it is reported to the cloud; when the device data is monitored as the device data of the sub-device under other gateways Data is not reported from the gateway to the cloud, that is, the gateway cannot report the device data of other gateway sub-devices to the cloud.
