Description

Technical Field

[0001] This invention relates to the field of intelligent low-voltage equipment access management in power distribution networks, and specifically to a cloud-edge-end adaptive access method and system for low-voltage intelligent power distribution equipment. Background Technology

[0002] The distribution IoT architecture is divided into "cloud-pipe-edge-device". The cloud refers to the cloud platform, where edge computing nodes interact with the cloud platform to achieve global management and control. The edge refers to the edge computing nodes, which are usually deployed on the low-voltage distribution transformer side and are responsible for data aggregation, processing and local analysis on the transformer side. The device refers to various smart devices, including smart circuit breakers, smart capacitors, temperature sensors, etc., which connect to the edge computing nodes to interact with them. The pipe refers to the communication method between the cloud, edge and device.

[0003] With the digital transformation of the power grid and the construction of the distribution Internet of Things, a large number of smart devices are connected to the distribution network, which also brings some difficulties to the operation and maintenance management of distribution network equipment: On the one hand, there are many types of smart devices in the distribution network and various communication protocols, including 645, 698, Modbus, etc., which makes the development, access and debugging of different smart distribution devices very labor-intensive; on the other hand, with the refinement of power grid operation and maintenance management and the diversification of user needs, the functional requirements for low-voltage equipment are also constantly changing, and communication protocols also need to be continuously upgraded and maintained to meet the ever-changing needs, making the current one-to-one upgrade and maintenance method extremely labor-intensive.

[0004] In existing technologies, end-device manufacturers develop corresponding communication protocol apps based on low-voltage equipment communication protocol documents, install and deploy them within the low-voltage smart devices, and manually import device ledger information, including the low-voltage equipment communication address, communication protocol, communication method, and corresponding edge device ID, into a cloud platform. This device ledger information is then distributed to the edge devices. The corresponding device app within the edge device reads the information, completes the file configuration, establishes the edge network, and enables data interaction with the end-devices. Therefore, existing technologies require the development and deployment of corresponding protocol apps within the end devices based on different device types and communication protocols. This development cycle is lengthy and labor-intensive. If protocol upgrades are required, manual software updates are necessary on both the end and edge devices, resulting in significant integration and debugging workloads.

[0005] Therefore, there is an urgent need to design an edge protocol adaptive access method and system for low-voltage intelligent power distribution equipment to achieve rapid communication access for end-side devices, thereby reducing the workload of low-voltage equipment development and access debugging. Summary of the Invention

The information extraction module is used to extract the self-registration information of the low-voltage intelligent power distribution equipment to be connected; A protocol matching module configured on an edge computing node is used to determine a protocol component based on the self-registration information and upload it to the protocol management module. This allows the protocol management module to call the corresponding protocol component and then distribute it to the low-voltage intelligent power distribution equipment via the edge computing node, thereby enabling the low-voltage intelligent power distribution equipment to achieve protocol matching based on the protocol component.

[0007] Optionally, the cloud-edge-device adaptive access system further includes various end-device access terminals configured on the edge computing node. The end-device access terminal is used to read the clock data of the low-voltage intelligent power distribution equipment after the protocol components are installed. If the reading is successful, the protocol matching is successful; if the reading fails, an alarm is triggered.

[0008] Optionally, the self-registration information includes the communication protocol identifier and device type.

[0009] Optionally, the protocol matching module is used to determine the protocol components based on the self-registration information and upload them to the protocol management module, specifically: The protocol matching module is used to determine the corresponding protocol component based on the pre-built registration information-protocol component mapping table and upload it to the protocol management module. The registration information-protocol component mapping table includes the mapping relationship between communication protocol identifier, device type and protocol component.

[0010] Optionally, the information extraction module includes basic general components and a data storage module. The data storage module is used to store the self-registration information of low-voltage intelligent power distribution equipment, and the basic general components are used to interact with the data storage module.

[0011] Optionally, the information extraction module is configured in a low-voltage intelligent power distribution device.

[0012] A second aspect of the present invention provides a cloud-edge adaptive access method for low-voltage intelligent power distribution equipment, comprising: In the power distribution cloud platform, the communication protocols of different low-voltage intelligent devices are encapsulated into protocol components; Extract the self-registration information of low-voltage intelligent power distribution equipment; Based on the self-registration information, the corresponding protocol components are determined and uploaded to the power distribution cloud platform; The power distribution cloud platform calls the corresponding protocol components and sends them to the low-voltage intelligent power distribution equipment; The low-voltage intelligent power distribution equipment is configured to receive protocol components to achieve protocol matching.

[0013] Preferably, the cloud-edge-device adaptive access method further includes: configuring a terminal device for access, wherein the terminal device for access reads the clock data of the low-voltage intelligent power distribution equipment after the protocol components are installed; if the reading is successful, the protocol matching is successful; if the reading fails, an alarm is triggered. Furthermore, the present invention also provides a computing device, including: at least one processor and a memory; The memory is used to store one or more programs; When the one or more programs are executed by the one or more processors, a cloud-edge adaptive access method for low-voltage intelligent power distribution equipment as described above is implemented.

[0014] In another aspect, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein when the computer program is executed, it implements the cloud-edge adaptive access method for low-voltage intelligent power distribution equipment as described above.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a cloud-edge adaptive access method and system for low-voltage intelligent power distribution equipment, comprising: a protocol library component and a protocol management module configured on a power distribution cloud platform, wherein the protocol library component is used to store protocol components encapsulated from the communication protocols of different low-voltage intelligent devices; the protocol management module is used to manage the protocol components; an information extraction module is used to extract the self-registration information of the low-voltage intelligent power distribution equipment to be accessed; and a protocol matching module configured on an edge computing node, wherein the protocol matching module is used to determine the protocol component according to the self-registration information and upload it to the protocol management module, so that the protocol management module calls the corresponding protocol component and distributes it to the low-voltage intelligent power distribution equipment through the edge computing node, thereby enabling the low-voltage intelligent power distribution equipment to achieve protocol matching based on the protocol component; this invention: 1) Significantly reduces the development difficulty and cost of edge devices: This invention introduces an architecture of "information extraction module + dynamically loaded protocol components," enabling standardized and universal production of edge device hardware and basic software. Device manufacturers do not need to develop different versions of device software for different protocols; they only need to ensure that the device can run the "information extraction module" and store self-describing information. This achieves "one-time hardware development, flexible protocol adaptation," significantly shortening the product development cycle and reducing software development investment and material management costs.

[0016] 2) Reduced workload for edge application development: "End device access terminals" in edge computing nodes can interface with standardized protocol components, eliminating the need to concern themselves with the specific protocol parsing details. When a new protocol is added, edge applications require little to no modification, as protocol parsing capabilities are handled by components distributed from the cloud. This improves the stability and maintainability of edge software.

[0017] 3) Achieving true "plug and play": After the new equipment is installed and powered on in the field, it can automatically complete the entire process of "self-registration - protocol matching - component distribution - installation verification," eliminating the need for technicians to perform tedious protocol configuration, driver installation, or software burning on-site. This reduces equipment access and commissioning time from hours to minutes, significantly improving the efficiency of power distribution network transformation, expansion, and equipment replacement, and reducing on-site construction labor costs and technical barriers.

[0018] 4) Enhanced System Compatibility and Scalability: Based on a unified protocol library in the cloud, the system can easily be compatible with new communication protocols or protocol variants that may emerge in the future. New protocol components can be developed and encapsulated in the cloud protocol library to support the access of new devices across the entire network. The system does not require large-scale overall upgrades or modifications, demonstrating excellent forward compatibility and ecosystem expansion capabilities. Attached Figure Description

Figure 3 This is a schematic diagram of the electronic device proposed in this invention. Detailed Implementation

[0020] This invention proposes a cloud-edge-device adaptive access method and system for low-voltage intelligent power distribution equipment. In the traditional model, each low-voltage intelligent power distribution device (such as smart meters and circuit breakers) requires deep customization development for the target communication protocol, tightly coupling the protocol stack with the device's main program. This invention introduces an architecture of "information extraction module + dynamically loaded protocol components," enabling standardized and universal production of end-device hardware and basic software. Equipment manufacturers no longer need to develop different versions of device software for different protocols; they only need to ensure that the device can run the "information extraction module" and store self-describing information. This achieves "one-time hardware development, flexible protocol adaptation," significantly shortening the product development cycle and reducing software development investment and material management costs.

[0021] Example 1: A cloud-edge-end adaptive access system for low-voltage intelligent power distribution equipment, such as Figure 1 As shown, it includes a protocol library component, a protocol management module, an information extraction module, and a protocol matching module.

[0022] The protocol library component and the protocol management module are configured on the power distribution cloud platform. The protocol library component is used to store protocol components encapsulated by the communication protocols of different low-voltage intelligent devices. The protocol management module is used to manage the protocol components.

[0023] Based on different low-voltage intelligent device communication protocols (such as DL / T 645, DL / T 698, Modbus, CoAP, etc.), they are encapsulated into different protocol components. The protocol components are decoupled from each other and stored in the protocol library component, which can be uniformly maintained and managed by the protocol management module.

[0024] The protocol management module is responsible for retrieving and distributing protocol components based on feedback information from downstream devices (such as protocols fed back by edge computing nodes and terminal access information of end devices).

[0025] The information extraction module is used to extract the self-registration information of the low-voltage smart power distribution equipment to be connected.

[0026] In a further preferred embodiment, the information extraction module includes a basic general-purpose component and a data storage module. The data storage module stores the self-registration information of the low-voltage intelligent power distribution equipment, and the basic general-purpose component interacts with the data storage module. The self-registration information includes communication protocol, device type, communication method, communication address, device ID, etc. The basic general-purpose component can read the self-registration information from the data storage module and upload it to the edge computing node via a physical link (such as RS485). The data storage module also stores operating data such as voltage, current, and harmonics.

[0027] In a further preferred embodiment, the information extraction module is configured in a low-voltage intelligent power distribution device.

[0028] The protocol matching module is configured on the edge computing node. The protocol matching module is used to determine the protocol component according to the self-registration information and upload it to the protocol management module, so that the protocol management module calls the corresponding protocol component and sends it to the low-voltage intelligent power distribution equipment through the edge computing node, thereby enabling the low-voltage intelligent power distribution equipment to achieve protocol matching based on the protocol component.

[0029] In a further preferred embodiment, the cloud-edge-device adaptive access system also includes various end-device access terminals (end-device apps) configured on the edge computing node. The end-device access terminal is used to read the clock data of the low-voltage intelligent power distribution equipment after the protocol components are installed. If the reading is successful, the protocol matching is successful; if the reading fails, an alarm is triggered.

[0030] The protocol matching module is also used to notify the terminal device to access the terminal device (low-voltage intelligent power distribution equipment) corresponding to the terminal for data communication.

[0031] The terminal device is also used to interact with corresponding low-voltage smart devices, including parameter querying, data retrieval, and control.

[0032] In a further preferred embodiment, the protocol matching module is used to determine the protocol components based on the self-registration information and upload them to the protocol management module, specifically as follows: The protocol matching module is used to determine the corresponding protocol component based on the pre-built registration information-protocol component mapping table and upload it to the protocol management module. The registration information-protocol component mapping table includes the mapping relationship between communication protocol identifier, device type and protocol component.

[0033] This invention modularly encapsulates the main standard protocols of low-voltage intelligent power distribution equipment, decoupling different components. This allows for distributed deployment to corresponding low-voltage intelligent power distribution devices, enabling protocol matching and access with different devices and facilitating normal data interaction. No protocol development is required within the low-voltage intelligent power distribution equipment itself, significantly reducing development workload. The cloud platform contains a standard protocol library and distributes corresponding protocol components to end devices via edge devices, ensuring protocol standardization across end devices. Furthermore, unified protocol upgrades and maintenance can be performed through the cloud platform, reducing the workload of debugging, access, and upgrades on end devices.

[0034] Example 2: Based on the same inventive concept, this invention also provides a cloud-edge adaptive access method for low-voltage intelligent power distribution equipment, such as... Figure 2 As shown, it includes: S1, in the power distribution cloud platform, encapsulates the communication protocols of different low-voltage intelligent devices into protocol components; S2, Extract the self-registration information of low-voltage intelligent power distribution equipment; S3, determine the corresponding protocol component based on the self-registration information and upload it to the power distribution cloud platform; S4, the power distribution cloud platform calls the corresponding protocol component and sends it to the low-voltage intelligent power distribution equipment; S5, the low-voltage intelligent power distribution equipment configures the received protocol components to achieve protocol matching.

[0035] In a further preferred embodiment, the cloud-edge-device adaptive access method further includes step S6: configuring the terminal device access terminal. After the low-voltage intelligent power distribution equipment completes the installation of the protocol components, the terminal device access terminal reads the clock data of the low-voltage intelligent power distribution equipment. If the reading is successful, the protocol matching is successful; if the reading fails, an alarm is triggered, and maintenance personnel can troubleshoot and maintain the equipment according to the prompts.

[0036] In step S2, after the low-voltage smart device is powered on, it can use the basic general components in the information extraction module to read the device's self-registration information from the data storage module, including communication protocol, device type, communication method, communication address, device ID, etc., and upload it to the edge computing node.

[0037] In step S3, after receiving the information, the "protocol matching module" in the edge computing node extracts the "communication protocol" and "device type," and preliminarily determines that the DL / T 645 protocol component should be used. The edge node uploads the identified protocol type (DL / T 645) and device ID to the "device protocol management module" of the cloud platform. The cloud platform protocol management module confirms the protocol component information, retrieves the standard DL / T 645 protocol component from the protocol library, and distributes it to the edge node through a secure channel. After receiving the protocol component, the edge node pushes it to the corresponding low-voltage intelligent device (end device).

[0038] The low-voltage intelligent device receives the communication protocol component, completes the component installation and deployment, interacts with the data storage module through the basic general components, and uploads the installation completion information to the edge device.

[0039] The cloud platform records the device registration status and incorporates it into unified management. Edge nodes report the "protocol matching successful" status to the cloud platform, which then updates the device ledger and includes the meter in the real-time monitoring and maintenance system.

Specifically, it is suitable for loading and executing one or more instructions in the storage medium to realize the corresponding method flow or corresponding function, so as to realize the steps of the cloud-edge adaptive access method of a low-voltage intelligent power distribution equipment in the above embodiments.

This readable storage medium is a memory device within an electronic device used to store programs and data. It is understood that the storage medium here can include both built-in storage media within the electronic device and extended storage media supported by the electronic device. The storage medium provides storage space, which stores the terminal's operating system. Furthermore, this storage space also stores one or more instructions suitable for loading and execution by a processor. These instructions can be one or more executable programs (including program code). It should be noted that the storage medium here can be high-speed RAM or non-volatile memory, such as at least one disk storage device.
