Description

Technical Field

[0001] The present invention relates to the field of smart grid control technology, and specifically to an intelligent data acquisition external module and data acquisition method for an electric energy meter based on 5G communication technology. Background Art

[0002] With the rapid development of smart grid technology, information and communication technology are deeply integrated with the power grid system, and its role in the development of smart grid is becoming increasingly significant. As the most advanced communication technology, 5G will be widely used in power system communication with its advantages such as large bandwidth, low latency, high reliability, and high connectivity. Compared with traditional power communication technology, 5G communication technology can better meet the development needs of communication technology for new energy grid connection, interactive power supply and demand of multiple users, close coupling and interaction between information technology and power system, high bandwidth of power grid, and low latency. It not only provides great convenience for people's production and life, but also promotes the rapid development of power system communication technology.

[0003] At present, the acquisition equipment and corresponding energy meter technology are becoming more and more mature. The data density of the acquisition module required by the power grid is getting smaller and smaller, and the data items are increasing. The amount of data communicated between the collector and the remote master station is getting larger and larger. However, ordinary 4G communication is limited by the uplink data bandwidth and latency, and the original energy data cannot be transmitted in time. As a result, the master station cannot process the data in time, which reduces the master station's ability to calculate and analyze the energy meter collection data, making it difficult to achieve real-time and accurate monitoring of the energy meter information.

[0004] The existing electric energy meter data acquisition solution based on carrier communication technology adopts a low-voltage power line carrier communication channel, and realizes information transmission between the master station and the electric energy meter through the PLC carrier module and the wireless communication module. The acquisition terminal controls the wireless communication module to exchange data with the master station through the uplink information channel, and its uplink information channel is realized by the public communication network.

[0005] When the master station requests to collect meter readings, the meter reading information is first sent by the master station to the wireless communication module, then transmitted to the application terminal by the wireless communication module, and then passed through the master node module and slave node module of the PLC carrier module. Finally, the meter reading information is collected and stored on the data and status information of the electric energy meter using the downlink channel.

[0006] In addition, the existing three-phase fee-controlled energy meter intelligent acquisition module solution based on 4G communication technology adopts 4G communication technology to realize local direct communication between the master station and the fee-controlled energy meter, reducing multiple communication links in data transmission, making data transmission efficient and convenient, and achieving the goal of fast and full collection. The intelligent acquisition module designed in this solution has multiple functions, that is, it can be used in conjunction with the energy meter to realize full collection of the energy meter, and it can also be functionally expanded to realize the miniaturization of the acquisition terminal. However, the energy meter data acquisition solution based on carrier communication technology requires multiple links for data request, reception, storage, and forwarding, and the data transmission efficiency is low. At the same time, the information transmission path of the existing technical solution is cumbersome, and the information transmission process is affected by the intermediate processing links, which reduces the reliability and stability of data acquisition.

[0007] Although the solution of the intelligent acquisition module of the three-phase fee-controlled energy meter based on 4G communication technology can achieve the goal of fast and full data collection, the 4G communication technology is limited by data bandwidth, latency and capacity, resulting in the inability of the master station to process and monitor the data in real time. In addition, the existing energy meter data acquisition solution based on 4G communication technology cannot achieve real-time positioning of the installation location of the energy meter, which is not convenient for the maintenance and management of the energy meter.

[0008] Therefore, there is an urgent need for an electric energy meter intelligent data collection external module based on 5G communication technology to solve the above-mentioned technical problems. Summary of the invention
