Detailed Description
In The prior art, The FTU mainly uses a Mobile Communication network to communicate with an automatic master station of a power distribution network, such as General Packet Radio Service (GPRS), The fourth generation Mobile Communication Technology (4G), and so on. In areas with poor mobile signal coverage, the FTU cannot effectively communicate with the distribution network automation master station. In order to solve the problem, a Beidou RDSS communication technology can be considered to be used for carrying out communication between the FTU and the power distribution network automation master station instead of or as an alternative communication mode of a mobile communication network.
The Beidou RDSS communication technology is a satellite communication technology, corresponding data are transmitted through Beidou RDSS short messages, the communication range span is large, the time delay is small, and the Beidou RDSS communication technology can be suitable for remote, cross-region and cross-platform data communication occasions.
The Beidou RDSS communication technology is limited by the influence of the communication bandwidth and the communication frequency of the Beidou RDSS communication technology, and is generally only suitable for application occasions with small communication data volume. However, the FTU has a high requirement on the real-time performance of communication, cannot directly adopt the existing big dipper RDSS communication technology, needs to perform certain optimization processing on the FTU, ensures that the FTU three remote data are timely and effectively transmitted, ensures that the switching information parameters, the working state, the remote signaling data and the remote measurement data of the power distribution network system are effectively monitored in real time, and ensures the normal operation of the power distribution network.
Therefore, in order to enable the Beidou RDSS communication technology to be applicable to data transmission and communication processes of a power distribution network system with high real-time requirements, the core concept of the embodiment of the application is that the transmission bottleneck problem of the existing Beidou single-channel technology is solved by configuring a plurality of RDSS logic channels in terminal equipment capable of achieving Beidou RDSS communication, and the reliability and timeliness of FTU three-remote data transmission are improved.
Fig. 1 is a schematic view of an application scenario of a communication method according to an embodiment of the present application. According to the scheme shown in fig. 1, a terminal with the Beidou RDSS remote multichannel communication function can be connected with an FTU through a physical interface, so that effective communication between the FTU and a power distribution network automation master station is realized based on the Beidou RDSS communication technology. Because the communication channel of the Beidou RDSS short message technology is a satellite wireless communication channel, the air-to-air communication mode is not influenced by the terrain and the topography, and the effective communication between the FTU and the power distribution network automation master station can be ensured in the areas without mobile network coverage. Meanwhile, based on the data processing of a plurality of logic channels, the data concurrency capability of the terminal equipment can be improved, and the real-time performance of data processing and transmission is improved.

The MCU control unit 205 is a core unit of the entire terminal device, and implements control, communication, channel adaptive switching, and communication interaction with the FTU device of each circuit unit. For the beidou RDSS link, the MCU control unit 205 needs to complete data analysis processing of the power data based on the beidou RDSS transmission link, and performs protocol processing on the analyzed power data according to a power communication protocol, so as to send the power data such as telemetry and remote signaling of the FTU to the distribution network automation master station, and send the remote control command from the master station to the FTU device.
