Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things applications, and in particular to a method and system for remotely upgrading intelligent agent equipment of a virtual power plant. Background Art

[0002] In the field of virtual power plants, with the continuous development of technology and the widespread aggregation of distributed resources, the remote upgrade of virtual power plant intelligent agent devices has become an important technical requirement. In the field of remote upgrade of virtual power plant intelligent agent devices, although the existing technology has made certain progress, it still has the following major problems and defects:

[0003] First, the problem of unified compatibility and issuance of gateway nodes: In the existing virtual power plant remote upgrade system, due to interface differences and compatibility issues between intelligent agents of different equipment manufacturers and models, it is difficult for the IoT platform to achieve unified compatibility and instruction issuance for all gateway nodes during the upgrade process. This not only increases the complexity and cost of system upgrades, but may also cause some intelligent agents to fail to receive upgrade instructions in a timely manner, thereby affecting the upgrade progress and effect of the entire system. This will result in low overall upgrade efficiency, high customized operation costs, and insufficient reliability of some terminal devices.

[0004] Second, the problem of gateway failure: During the remote upgrade process, if the intelligent agent fails due to network failure, hardware failure or other reasons, the existing technology often lacks an effective response mechanism to ensure the continuity and reliability of the upgrade process. Once the gateway fails, subsequent upgrade instructions may not be delivered, which will affect the smooth progress of the entire upgrade process. This will cause upgrade interruption, data loss, system instability and other problems.

[0005] In the prior art CN117938978A, a multi-protocol support access method based on a virtual power plant discloses S1, system startup and initialization of the automation method: S2, system self-check and resource preparation: S3, equipment parameter pre-configuration: S4, gateway configuration and initialization: S5, equipment access and configuration application: S6, automation method operation and monitoring: S7, system optimization and continuous improvement.

[0006] In the prior art, data is transmitted between the system and the device through a gateway. However, in the event of a gateway failure, data transmission will be interrupted, and no backup technical means are mentioned for the event of a gateway failure, thereby interrupting the upgrade process. Summary of the invention

[0007] In order to solve the above problems existing in the prior art, the present invention proposes a method and system for remote upgrading of virtual power plant intelligent agent equipment.

[0008] The technical solution of the present invention is as follows:

[0009] On the one hand, the present invention provides a method for remotely upgrading a virtual power plant intelligent agent device, the specific steps of which include:

[0010] Construct a stable upgrade system architecture including an IoT platform, an intelligent agent device, and an upgrade package storage server. An upgrade instruction receiving module and an upgrade instruction parsing module are deployed on the intelligent agent device. A unified upgrade interface and message protocol are set on the upgrade instruction receiving module.

[0011] The upgrade instruction is sent from the IoT platform to the upgrade instruction receiving module on the intelligent agent device, and the upgrade instruction receiving module forwards the upgrade instruction to the upgrade instruction parsing module;

[0012] The upgrade instruction parsing module downloads the corresponding upgrade package from the upgrade package storage server according to the upgrade instruction, decompresses the upgrade package and executes the upgrade script;

[0013] When the intelligent agent device fails, the upgrade command cannot be transmitted to the upgrade command receiving module. The IoT platform system directly detects and connects to the upgrade command parsing module to transmit the upgrade package.

[0014] After completing the upgrade script, a return value indicating the upgrade completion status is generated in the upgrade instruction parsing module, and the return value is sent to the upgrade instruction receiving module, which then sends it back to the IoT platform, and the upgrade result is displayed on the IoT platform based on the return value.

[0015] As a preferred implementation, the IoT platform sends an upgrade instruction to the upgrade instruction receiving module through a unified upgrade interface, wherein the upgrade instruction is an MQTT message containing upgrade information, and the upgrade information includes a download address and version number of the upgrade package.

[0016] As a preferred implementation, an OMApp program is deployed on the upgrade instruction parsing module, and the OMApp program assembles a file download wget instruction based on the download address of the upgrade package in the upgrade information and then downloads the upgrade package file from the upgrade package storage server through the external network.

[0017] As a preferred implementation, a LinkApp program is deployed on the upgrade instruction receiving module, and the upgrade instruction receiving module maintains communication with the Internet of Things platform through the MQTT protocol.

[0018] As a preferred implementation, a rollback mechanism is established in the upgrade instruction parsing module, and when the system upgrade fails, the system of the intelligent device is restored to the state before the upgrade.

[0019] On the other hand, the present invention provides a system for remotely upgrading a virtual power plant intelligent agent device, comprising:

[0020] The remote upgrade framework construction module builds a stable upgrade system architecture including the IoT platform, the intelligent agent device and the upgrade package storage server. An upgrade instruction receiving module and an upgrade instruction parsing module are deployed on the intelligent agent device. A unified upgrade interface and message protocol are set on the upgrade instruction receiving module.

[0021] An upgrade instruction receiving module sends an upgrade instruction from the IoT platform to the upgrade instruction receiving module on the intelligent agent device, and the upgrade instruction receiving module forwards the upgrade instruction to the upgrade instruction parsing module;

[0022] An upgrade instruction parsing module, which downloads the corresponding upgrade package from the upgrade package storage server according to the upgrade instruction, decompresses the upgrade package and executes the upgrade script;

[0023] Upgrade instruction transparent transmission module: when the intelligent agent device fails, the upgrade instruction cannot be transmitted to the upgrade instruction receiving module. The IoT platform system directly detects and connects to the upgrade instruction parsing module to transmit the upgrade package;

[0024] After completing the upgrade script, the upgrade result judgment module generates a return value indicating the upgrade completion status in the upgrade instruction parsing module, and sends the return value to the upgrade instruction receiving module, which then sends it back to the IoT platform. The upgrade result is displayed on the IoT platform based on the return value.

[0025] As a preferred implementation, the IoT platform sends an upgrade instruction to the upgrade instruction receiving module through a unified upgrade interface, wherein the upgrade instruction is an MQTT message containing upgrade information, and the upgrade information includes a download address and version number of the upgrade package.

[0026] As a preferred implementation, an OMApp program is deployed on the upgrade instruction parsing module, and the OMApp program assembles a file download wget instruction based on the download address of the upgrade package in the upgrade information and then downloads the upgrade package file from the upgrade package storage server through the external network.

[0027] As a preferred implementation, a LinkApp program is deployed on the upgrade instruction receiving module, and the upgrade instruction receiving module maintains communication with the Internet of Things platform through the MQTT protocol.

[0028] As a preferred implementation, a rollback mechanism is established in the upgrade instruction parsing module, and when the system upgrade fails, the system of the intelligent device is restored to the state before the upgrade.

[0029] The present invention has the following beneficial effects:

[0030] 1. The present invention defines a unified upgrade interface and message protocol, ensuring that the IoT platform can seamlessly connect to intelligent agents of different manufacturers and models, and realizes the unified issuance and reception of upgrade instructions. This greatly simplifies the upgrade process, improves upgrade efficiency, and reduces the cost of customized operations.

[0031] 2. The present invention realizes the automation of the whole process from downloading, decompressing, executing and feedback of upgrade results of the upgrade package. By writing automated upgrade scripts and instructions, manual intervention is reduced and the stability and accuracy of the upgrade are improved. At the same time, the automated upgrade process also greatly reduces the operation and maintenance costs.

[0032] 3. The present invention introduces a transparent transmission mechanism to address the possible failure of the intelligent agent. During the upgrade process, if the intelligent agent fails, the system can automatically detect and directly connect to the relevant devices under the gateway to ensure the continuity and integrity of the upgrade process. This mechanism greatly improves the reliability and stability of the upgrade process.

[0033] 4. The present invention aims at unexpected situations that may occur during system upgrades. When the system upgrade fails, in order to protect the security of the system itself and the errors that may occur during the upgrade process, the system that failed to upgrade is restored to the state before the upgrade to ensure the security of the system.

A unified upgrade interface and message protocol are set on the upgrade instruction receiving module.

[0045] In this embodiment, the detailed overview of the components of the IoT platform, the intelligent agent device, and the upgrade package storage server is as follows:

[0046] IoT Platform

[0047] Function description: As the control center of the remote upgrade system, the IoT platform is responsible for initiating upgrade requests, sending upgrade instructions, receiving upgrade responses and displaying upgrade results.

[0048] Technical implementation: The IoT platform calls a unified upgrade interface to send an MQTT message containing upgrade information to the intelligent agent. The message includes key information such as the download address and version number of the upgrade package.

[0049] The intelligent agent device is deployed with LinkApp program and OMApp program, as follows:

[0050] LinkApp

[0051] Function description: As the middleware on the intelligent agent, it is responsible for receiving MQTT messages sent by the IoT platform and forwarding them to the OMApp program.

[0052] Technical implementation: The LinkApp program maintains communication with the IoT platform through the MQTT protocol to ensure the accurate transmission of upgrade instructions.

[0053] OMApp Program

[0054] Function description: Responsible for parsing the upgrade instructions in the MQTT message, assembling the wget command to download the upgrade package from the server specified by the IoT platform, executing the upgrade script, and returning the upgrade result.

[0055] Technical implementation:

[0056] Message parsing: The OMApp program parses the MQTT message and extracts key information such as the upgrade package download address.

[0057] Download the upgrade package: Use the wget command to download the upgrade package file from the server specified by the IoT platform through the external network.

[0058] Execute the upgrade script: After downloading, decompress the upgrade package and execute the upgrade script to complete the device upgrade.

[0059] Result feedback: Based on the upgrade results, assemble and send the MQTT response message to the IoT platform.

[0060] Upgrade package storage server

[0061] Function description: Store and provide the latest upgrade package files for intelligent agent to download.

[0062] Technical implementation: The upgrade package storage server is usually deployed in the cloud or in the enterprise intranet to ensure the security and accessibility of the upgrade package.

[0063] The upgrade instruction is sent from the IoT platform to the upgrade instruction receiving module on the intelligent agent device, and the upgrade instruction receiving module forwards the upgrade instruction to the upgrade instruction parsing module;

[0064] The upgrade instruction parsing module downloads the corresponding upgrade package from the upgrade package storage server according to the upgrade instruction, decompresses the upgrade package and executes the upgrade script;

[0065] When the intelligent agent device fails, the upgrade command cannot be transmitted to the upgrade command receiving module. The IoT platform system directly detects and connects to the upgrade command parsing module to transmit the upgrade package.

[0066] After completing the upgrade script, a return value indicating the upgrade completion status is generated in the upgrade instruction parsing module, and the return value is sent to the upgrade instruction receiving module, which then sends it back to the IoT platform, and the upgrade result is displayed on the IoT platform based on the return value.

[0067] In this embodiment, if Figure 2The specific implementation of each step is as follows:

[0068] Upgrade command initiated

[0069] IoT platform: The IoT platform of the virtual power plant sends an MQTT message through its upgrade interface, which contains relevant information required for the upgrade, such as the location and version number of the upgrade package.

[0070] Message reception and forwarding

[0093] Standardized naming: All software versions should follow unified naming rules to distinguish the functional differences and release times between different versions.

[0094] Compatibility assessment: Before upgrading a version, a strict compatibility assessment must be conducted on the new version to ensure its compatibility with existing systems, hardware devices, and other software components.

[0095] Data security: During the upgrade process, the security and integrity of data should be ensured, and necessary backup and recovery measures should be taken to prevent data loss or damage.

[0096] Phased implementation: Divide the upgrade process into multiple phases based on the complexity and impact of the upgrade content, and proceed step by step to reduce risks.
