[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] The node management method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, agent node 102 communicates with edge node 104 via a serial port and with central node 106 via a network. Edge node 104 connects to serial devices via a serial port, has low processing power and storage resources, and is used to collect and process data from serial devices. Edge node 104 can be a computer device, hardware server, etc. Agent node 102 has strong processing power, storage capacity, and network connectivity, and can act as a bridge between edge node 104 and central node 106. Agent node 102 can be a computer device, hardware server, etc. Central node 106 is the core of the edge network, responsible for unified management, task allocation, and resource scheduling of edge node 104 based on the information collected by agent node 102. Central node 106 can be a computer device, hardware server, virtual machine, cloud server, etc.

[0055] In one embodiment, such as Figure 2 As shown, this application provides a node management method for application Figure 1 Taking the edge nodes in the 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 agent node or the central node. The registration request instruction includes information such as data format requirements and registration timeout. The agent node can send the registration request instruction to the target edge node via serial port, instructing the target edge node to send the registration information according to the data format requirements within the registration timeout period.

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

[0059] The registration data packet includes identification information and state information of the target edge node, and can be encapsulated in a json format. The identification information can include device ID, device type, function description and the like, and the state information includes running state, resource usage and the like.

[0060] In step 206, the registration data packet is sent to the center node to register the target edge node.

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

[0062] In step 208, in the case that the target edge node is successfully registered, task information is sent to the target edge node in response to a control instruction of the center node to instruct the target edge node to perform a corresponding task according to the task information.

[0063] After the target edge node is successfully registered in the center node, the center node includes the target node in the management range and performs task allocation and scheduling on the target node. Specifically, the center node sends a control instruction to the proxy node through the network, and the proxy node sends task information to the target edge node in response to the control instruction. After the target edge node receives the task information, it performs a corresponding task according to the task information.

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

[0065] In one embodiment, before sending the registration request instruction to the edge node, the node management method further comprises the steps of: sending a probe message to all edge nodes connected to the proxy node, obtaining response messages generated by all edge nodes based on the probe message, and taking the edge node corresponding to the response message meeting the preset registration condition as the target edge node.

[0066] The probe message comprises the node ID of the proxy node. The response message comprises the device ID of the edge node. The preset registration condition indicates that the device ID of the edge node is within the device ID range managed by the proxy node and has not completed registration at the center node.

[0067] It can be understood that the proxy node can periodically send a probe message to all edge nodes connected thereto, obtain response messages generated by all edge nodes based on the probe message, obtain the device ID of the corresponding edge node according to the response message, take the edge node corresponding to the device ID as the target edge node if the device ID is within the device ID range, and save the serial port address and device ID of the target edge node and the like information to prepare for the subsequent registration process.

[0068] In one embodiment, sending the registration data packet to the center node to register the target edge node comprises the steps of: judging whether the registration data packet is complete according to the data format and the checksum of the registration data packet, converting the registration data packet into registration information meeting the format requirements of the center node in the case that the registration data packet is complete, and sending the registration information to the center node to register the target edge node.

[0069] It can be understood that the proxy node first obtains the data format and the checksum of the registration data packet, judges whether the registration data packet is complete according to the data format and the checksum, converts the registration data packet into registration information meeting the format requirements of the center node if it is determined that the registration data packet is complete according to the data format and the checksum, and sends the registration information to the center node to register the target edge node, while the proxy node sends a verification passed message to the edge node.

[0070] In one embodiment, the node management method further comprises the steps of: obtaining task execution information generated by the target edge node in the process of executing a task, and sending the task execution information to the center node.

[0071] The task execution information includes intermediate result files and running data generated during the target edge node executing the task, and the like. The proxy node can acquire the task execution information of the target edge node, and send the task execution information to the center node, so that the center node can monitor the running status of the target edge node in real time.

[0072] Based on the same inventive concept, the embodiments of the present application also provide a proxy server for implementing the above-mentioned node management method. The proxy server provides a solution to the problem similar to the solution provided in the above-mentioned method, and therefore the specific limitations in one or more embodiments of the proxy server provided below can refer to the limitations of the node management method provided above, and will not be described here again.

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

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

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

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

[0077] The task sending module 308 is configured to, in the case that the target edge node is successfully registered, send task information to the target edge node in response to a control instruction of the center node, so as to instruct the target edge node to execute a corresponding task according to the task information.

[0078] In one embodiment, the proxy server further includes a target edge node determination module configured to send a probe packet to all edge nodes connected to the proxy node, acquire response packets generated by all edge nodes based on the probe packet, and determine an edge node corresponding to a response packet satisfying a preset registration condition as the target edge node.

[0079] In one embodiment, the registration module is further configured to determine whether the registration data packet is complete according to a data format and a checksum of the registration data packet, convert the registration data packet into registration information satisfying a format requirement of the center node in the case that the registration data packet is complete, and send the registration information to the center node to register the target edge node.

[0080] In one embodiment, the proxy server further comprises a proxy monitoring module configured to acquire task execution information generated by the target edge node in the process of executing the task, and send the task execution information to the center node.

[0081] In one embodiment, as shown in Figure 4 The present application further provides a node management method, applied to an edge node in Figure 1 , and comprising steps 402-406.

[0082] In step 402, in response to a registration request instruction of a proxy node, a registration data packet is sent to the proxy node to instruct the proxy node to send the registration data packet to a center node to register the edge node.

[0083] After receiving the registration request instruction of the proxy node, the edge node sends 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 center node to register the edge node.

[0084] In step 404, in the case where the edge node is successfully registered, task information generated by the proxy node according to a control instruction of the center node is acquired.

[0085] After the edge node is successfully registered in the center node, the center node includes the edge node in the management range, and assigns a task to the edge node according to the function description and resource usage of the edge node. Specifically, the center node can first send a control instruction to the proxy node, the proxy node generates corresponding task information according to the control instruction, and sends the task information to the edge node.

[0086] In step 406, a corresponding task is executed according to the task information.

[0087] The edge node can execute a corresponding task according to the 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 a registration request instruction of the proxy node to instruct the proxy node to send the registration data packet to the center node to register the edge node, acquires task information generated by the proxy node according to a control instruction of the center node in the case where the edge node is successfully registered, and executes a corresponding task according to the task information, thereby realizing registration in the center node and being managed. The edge node can immediately interact with the center node through the proxy node, and effectively solves the problem that the edge node cannot communicate with the center node due to limited resources.

[0089] In one embodiment, before sending the registration data packet to the agent node, the node management method further comprises the steps of sending a query instruction to a serial device connected to the edge node to obtain identification information of the serial device, obtaining state information of itself, and generating the registration data packet according to the identification information and the state information.

[0090] The identification information includes device ID, device type, and function description, etc. The state information includes running state (normal operation or fault) and resource usage, etc. It can be understood that the edge node can send a query instruction to the serial device through the serial port when starting, obtain the identification information of the serial device, and obtain the state information of itself, and then encapsulate the identification information and the state information into a registration data packet in json format.

[0091] In one embodiment, the edge node can also send the generated task execution information to the agent node periodically during the execution of the task, so that the agent node sends the task execution information to the center node, and the center node can monitor the running status of the edge node in real time.

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

[0093] In one embodiment, as shown in Figure 5 , an edge server is provided, which includes a data packet sending module 502, a task obtaining module 504, and a task execution module 506.

[0094] The data packet sending module 502 is configured to send a registration data packet to an agent node in response to a registration request instruction of the agent node, so as to instruct the agent node to send the registration data packet to a center node and register the edge node.

[0095] The task obtaining module 504 is configured to obtain task information generated by the agent node according to a control instruction of the center node in the case that the edge node is successfully registered.

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

[0097] In one embodiment, the edge server further includes a data packet generation module configured to send a query instruction to a serial device connected to the edge node to obtain identification information of the serial device, obtain state information of itself, and generate a registration data packet according to the identification information and the state information.

[0098] In one embodiment, as shown in Figure 6 The application also provides a node management method, which is applied to Figure 1 The center node in the system includes steps 602-606.

[0099] Step 602: 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.

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

[0101] Step 604: Generate a control instruction in the case of successful registration of the target edge node.

[0102] Step 606: Send the 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 center node can assign a corresponding task to the target edge node, send a control instruction containing task information to the proxy node, and send the task information to the target edge node by the proxy node, so that the target edge node can execute the corresponding task according to the task information.

[0104] In the embodiment of the application, the center node registers 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, and in the case of successful registration of the target edge node, a control instruction is generated, which is sent 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, which realizes the registration and unified management of the edge node and improves the management efficiency of the system.

[0105] In one embodiment, in the case of successful registration of the target edge node, 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 in the case of successful registration of the target edge node, querying the center node for the to-be-assigned task according to the function and resource usage, determining the target assignment task, and generating the control instruction according to the task information of the target assignment 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 a task suitable for the target edge node from the to-be-assigned tasks, i.e., a target assignment task, and generate a control instruction according to the task information of the target assignment task. For example, if the function description of the target edge node is to collect data of a sensor, the central node can assign a data collection task in the to-be-assigned tasks as the target assignment task, generate a control instruction according to the task information of the data collection task, and send the control instruction to the proxy node, which then sends the task information to the target edge node, so that the target edge node executes the data collection task.

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

[0108] In one embodiment, as shown in Figure 7 a central server is provided, which includes a registration module 702, a control instruction generation module 704, and a control instruction sending module 706.

[0109] The registration module 702 is configured 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 configured to generate a control instruction in the case that the registration of the target edge node is successful.

[0111] The control instruction sending module 706 is configured to send the 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 a corresponding task according to the task information.

[0112] In one embodiment, the control instruction generation module is further configured to obtain the function and resource usage of the target edge node according to the registration data packet in the case that the registration of the target edge node is successful; query the to-be-assigned tasks in the central node according to the function and resource usage, determine a target assignment task, and generate a control instruction according to the task information of the target assignment task.
