[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The node management method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the proxy node 102 communicates with the edge node 104 through the serial port and communicates with the central node 106 through the network. The edge node 104 can be connected to the serial port device through the serial port, has low processing power and storage resources, and is used to collect and process the data of the serial port device. The edge node 104 can be a computer device, a hardware server, etc. The proxy node 102 has strong processing power, storage capacity and network connection capabilities, and can serve as a bridge between the edge node 104 and the central node 106. The proxy node 102 can be a computer device, a hardware server, etc. The central node 106 is the core of the edge network, which is responsible for unified management, task allocation and resource scheduling of the edge node 104 according to the information collected by the proxy node 102. The central node 106 can be a computer device, a hardware server, a virtual machine and a cloud server, etc.

[0055] In one embodiment, Figure 2 As shown, the present application provides a node management method, using Figure 1 Taking the edge node in as an example, steps 202-208 are included.

[0056] Step 202: Send a registration request instruction to the target edge node.

[0057] The target edge node is an edge node in the edge network that has not yet completed registration with the proxy node or the central node. The registration request instruction includes information such as data format requirements and registration timeout. The proxy node can send a registration request instruction to the target edge node through the serial port to instruct the target edge node to send the registration information within the registration timeout according to the data format requirements.

[0058] Step 204: Receive a registration data packet returned by the target edge node based on the registration request instruction.

[0059] The registration data packet includes the identification information and status information of the target edge node, and the registration data packet can be encapsulated in JSON format. Among them, the identification information may include information such as device ID, device type, and function description, and the status information includes information such as operating status and resource usage.

[0060] Step 206: Send the registration data packet to the central node to register the target edge node.

[0061] After the proxy node establishes a network connection with the central node, it can send the registration data packet of the target edge node to the central node to register the target edge node in the central node.

[0062] Step 208, when the target edge node is successfully registered, in response to the control instruction of the central node, task information is sent to the target edge node to instruct the target edge node to perform the corresponding task according to the task information.

[0063] After the target edge node successfully registers with the central node, the central node will include the target edge node in the management scope and perform task allocation and scheduling on the target node. Specifically, the central node will send a control instruction to the proxy node through the network, and the proxy node will respond to the control instruction and send task information to the target edge node. After receiving the task information, the target edge node will execute the corresponding task according to the task information.

[0064] In this embodiment, by sending a registration request instruction to the target edge node, receiving the registration data packet returned by the target edge node based on the registration request instruction, and sending the registration data packet to the central node, the target edge node is registered. When the target edge node is successfully registered, in response to the control instruction of the central node, task information is sent to the target edge node to instruct the target edge node to perform the corresponding task according to the task information, thereby realizing data interaction between the edge node and the central node. It can be understood that the proxy node can serve as a bridge between the central node and the edge node, sending the registration information of the edge node to the central node, and sending the task information generated by the central node to the edge node. In this way, the edge node does not need to have strong network connection capabilities and processing capabilities, and only needs to communicate with the proxy node through the serial port to realize registration with the central node, which effectively solves the problem that the edge node cannot communicate with the central node due to limited resources. In addition, the central node can uniformly manage and schedule the edge nodes through the proxy node, thereby improving management efficiency and resource utilization.

[0065] In one embodiment, before sending a registration request instruction to the edge node, the node management method also includes: sending a detection message to all edge nodes connected to the proxy node, obtaining a response message generated by all edge nodes based on the detection message, and taking the edge node corresponding to the response message that meets the preset registration conditions as the target edge node.

[0066] The detection message includes the node ID of the proxy node. The response message includes the device ID of the edge node. The preset registration condition means that the device ID of the edge node is within the device ID range managed by the proxy node and has not completed registration in the central node.

[0067] It can be understood that the proxy node can periodically send detection messages to all edge nodes connected to it, and obtain the response messages generated by all edge nodes in response to the detection messages, and obtain the device ID of the corresponding edge node according to the response message. If the device ID is within the device ID range, the edge node corresponding to the device ID is used as the target edge node, and the serial port address and device ID of the target edge node and other information are saved to prepare for the subsequent registration process.

[0068] In one embodiment, a registration data packet is sent to a central node to register a target edge node, including: judging whether the registration data packet is complete based on a data format and a checksum of the registration data packet; if the registration data packet is complete, converting the registration data packet into registration information that meets the format requirements of the central node; and sending the registration information to the central node to register the target edge node.

[0069] It can be understood that the proxy node first obtains the data format and checksum of the registration data packet, and determines whether the registration data packet is complete based on the data format and checksum. If the registration data packet is determined to be complete based on the data format and checksum, the proxy node will convert the registration data packet into registration information that meets the format requirements of the central node, and send the registration information to the central node to register the target edge node. At the same time, the proxy node will send a verified message to the edge node. If the registration data packet is determined to be wrong or incomplete based on the data format and checksum, the proxy node will send a verified message to the edge node through the serial port to instruct the edge node to resend the registration data packet.

[0070] In one embodiment, the node management method further includes the steps of obtaining task execution information generated by the target edge node during the task execution process, and sending the task execution information to the central node.

[0071] The task execution information includes the intermediate result files and operation data generated during the task execution of the target edge node. The proxy node can obtain the task execution information of the target edge node and send the task execution information to the central node so that the central node can monitor the operation of the target edge node in real time.

[0072] Based on the same inventive concept, the embodiment of the present application also provides a proxy server for implementing the node management method involved above. The implementation scheme for solving the problem provided by the proxy server is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of one or more proxy servers provided below can refer to the limitations on the node management method above, and will not be repeated here.

[0073] In one embodiment, Figure 3 As shown, a proxy server is provided, including a registration request module 302 , a data packet acquisition module 304 , a registration data sending module 306 and a task sending module 308 .

[0074] The registration request module 302 is used to send a registration request instruction to a target edge node.

[0075] The data packet acquisition module 304 is used to receive the registration data packet returned by the target edge node based on the registration request instruction.

[0076] The registration data sending module 306 is used to send the registration data packet to the central node to register the target edge node.

[0077] The task sending module 308 is used to send task information to the target edge node in response to the control instruction of the central node when the target edge node is successfully registered, so as to instruct the target edge node to perform the corresponding task according to the task information.

[0078] In one embodiment, the proxy server also includes a target edge node determination module, which is used to send detection messages to all edge nodes connected to the proxy node; obtain response messages generated by all edge nodes based on the detection messages; and use the edge node corresponding to the response message that meets the preset registration conditions as the target edge node.

[0079] In one embodiment, the registration module is also used to determine whether the registration data packet is complete based on the data format and checksum of the registration data packet; if the registration data packet is complete, convert the registration data packet into registration information that meets the format requirements of the central node; and send the registration information to the central node to register the target edge node.

[0080] In one embodiment, the proxy server further includes a proxy monitoring module, which is used to obtain task execution information generated by the target edge node during the task execution process; and send the task execution information to the central node.

[0081] In one embodiment, Figure 4 As shown, the present application also provides a node management method, which is applied to Figure 1 The edge node in the embodiment includes steps 402-406.

[0082] Step 402, in response to the registration request instruction of the proxy node, sending a registration data packet to the proxy node to instruct the proxy node to send the registration data packet to the central node to register the edge node.

[0083] After receiving the registration request instruction from the proxy node, the edge node will send a registration data packet to the proxy node. The proxy node can receive the registration data packet and send the registration data packet to the central node to register the edge node.

[0084] Step 404: When the edge node is successfully registered, the task information generated by the proxy node according to the control instruction of the central node is obtained.

[0085] After the edge node successfully registers with the central node, the central node will include the edge node in the management scope and assign tasks to the edge node based on the edge node's functional description and resource usage information. Specifically, the central node can first send a control instruction to the proxy node, and the proxy node generates the corresponding task information based on the control instruction and sends the task information to the edge node.

[0086] Step 406, executing the corresponding task according to the task information.

[0087] Edge nodes can perform corresponding tasks based on task information.

[0088] In the embodiment of the present application, the edge node sends a registration data packet to the proxy node in response to the registration request instruction of the proxy node, so as to instruct the proxy node to send the registration data packet to the central node to register the edge node. When the edge node is successfully registered, the task information generated by the proxy node according to the control instruction of the central node is obtained, and the corresponding task is performed according to the task information, so as to realize the registration and management of the central node. The edge node can interact with the central node through the proxy node immediately, which effectively solves the problem that the edge node cannot communicate with the central node due to limited resources.

[0089] In one embodiment, before sending a registration data packet to the proxy node, the node management method also includes sending a query instruction to the serial port device connected to the edge node to obtain identification information of the serial port device, obtain its own status information, and generate a registration data packet based on the identification information and status information.

[0090] The identification information includes information such as device ID, device type and function description. The status information includes information such as operation status (normal operation or failure) and resource usage. It can be understood that when the edge node is started, it can send a query command to the serial port device through the serial port to obtain the identification information of the serial port device and its own status information, and then encapsulate the identification information and status information into a registration data packet in json format.

[0091] In one embodiment, during the execution of a task, the edge node may also periodically send the generated task execution information to the proxy node, so that the proxy node sends the task execution information to the central node, so that the central node can monitor the operating status of the edge node in real time.

[0092] Based on the same inventive concept, the embodiment of the present application also provides an edge server for implementing the node management method involved above. The implementation scheme for solving the problem provided by the edge server is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of one or more edge servers provided below can refer to the limitations of the node management method above, and will not be repeated here.

[0093] In one embodiment, Figure 5 As shown, an edge server is provided, including a data packet sending module 502 , a task acquisition module 504 and a task execution module 506 .

[0094] The data packet sending module 502 is used to send a registration data packet to the proxy node in response to the registration request instruction of the proxy node, so as to instruct the proxy node to send the registration data packet to the central node to register the edge node.

[0095] The task acquisition module 504 is used to acquire the task information generated by the proxy node according to the control instruction of the central node when the edge node is successfully registered.

[0096] The task execution module 506 is used to execute the corresponding task according to the task information.

[0097] In one embodiment, the edge server also includes a data packet generation module, which is used to send a query instruction to the serial port device connected to the generation edge node to obtain identification information of the serial port device; obtain its own status information; and generate a registration data packet based on the identification information and status information.

[0098] In one embodiment, Figure 6 As shown, the present application also provides a node management method, which is applied to Figure 1 Taking the central node in as an example, steps 602-606 are included.

[0099] Step 602, registering the target edge node according to the registration data packet sent by the proxy node; the registration data packet is generated by the target edge node in response to the registration request instruction of the proxy node.

[0100] It is understood that the central node can register the target edge node according to the registration data packet sent by the proxy node. Specifically, the central node will first verify the integrity and legality of the registration data packet. If the verification is successful, the central node will send a central message of verification to the proxy node and include the target edge node in the management scope.

[0101] Step 604: When the target edge node is successfully registered, a control instruction is generated.

[0102] Step 606: Send a control instruction to the proxy node to instruct the proxy node to send task information to the target edge node, and the target edge node executes the corresponding task according to the task information.

[0103] After the target edge node is successfully registered, the central node can assign corresponding tasks to the target edge node, send control instructions containing task information to the agent node, and the agent node sends the task information to the target edge node, so that the target edge node can perform corresponding tasks according to the task information.

[0104] In an embodiment of the present application, the central node registers the target edge node based on the registration data packet sent by the proxy node. The registration data packet is generated by the target edge node in response to the registration request instruction of the proxy node. When the target edge node is successfully registered, a control instruction is generated and sent to the proxy node to instruct the proxy node to send task information to the target edge node. The target edge node performs the corresponding task according to the task information, thereby realizing the registration and unified management of the edge nodes and improving the management efficiency of the system.

[0105] In one embodiment, when the target edge node is successfully registered, a control instruction is generated, including the steps of obtaining the function and resource usage of the target edge node according to the registration data packet, querying the tasks to be assigned in the central node according to the function and resource usage, determining the target assigned task, and generating a control instruction according to the task information of the target assigned task.

[0106] It can be understood that the central node can obtain the function and resource usage of the target edge node by analyzing the registration data packet, configure the task suitable for the target edge node from the tasks to be assigned, that is, the target allocation task, and generate a control instruction according to the task information of the target allocation task. For example, if the functional description of the target edge node is to collect sensor data, then the central node can assign the data collection task in the tasks to be assigned as the target allocation task, generate a control instruction according to the task information of the data collection task, and send it to the proxy node, and then the proxy node sends the task information to the target edge node, so that the target edge node performs the data collection task.

[0107] Based on the same inventive concept, the embodiment of the present application also provides a central server for implementing the node management method involved above. The implementation scheme for solving the problem provided by the central server is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of one or more central servers provided below can refer to the limitations on the node management method above, and will not be repeated here.

[0108] In one embodiment, Figure 7 As shown, a central server is provided, including a registration module 702 , a control instruction generating module 704 and a control instruction sending module 706 .

[0109] The registration module 702 is used to register the target edge node according to the registration data packet sent by the proxy node; the registration data packet is generated by the target edge node in response to the registration request instruction of the proxy node.

[0110] The control instruction generation module 704 is used to generate a control instruction when the target edge node is successfully registered.

[0111] The control instruction sending module 706 is used to send a control instruction to the proxy node to instruct the proxy node to send task information to the target edge node, and the target edge node executes the corresponding task according to the task information.

[0112] In one embodiment, the control instruction generation module is also used to obtain the function and resource usage of the target edge node according to the registration data packet when the target edge node is successfully registered; query the tasks to be assigned in the central node according to the function and resource usage, and determine the target assigned tasks; generate control instructions according to the task information of the target assigned tasks.
