BeiDou short message communication-based electric power data acquisition transmission processing system and method

Abstract

A BeiDou short message communication-based electric power data acquisition transmission processing system provided by the present invention comprises a plurality of electricity meters, a concentrator, a concentrator-side BeiDou communication terminal, a master station-side BeiDou communication terminal and a master station, wherein the electricity meters acquire the electric power data information; the concentrator is connected with the plurality of electricity meters, can package the electric power data information sent from the electricity meters into the data messages of a 376.1 protocol, and sends the messages to the concentrator-side BeiDou communication terminal; the concentrator-side BeiDou communication terminal analyzes, processes and packages the received data messages of the 376.1 protocol into the BeiDou short messages, and then sends to the master station-side BeiDou communication terminal via a transmission channel of a BeiDou satellite; the master station-side BeiDou communication terminal is connected with the concentrator-side BeiDou communication terminal via a BeiDou communication channel, receives the above BeiDou short messages, analyzes, processes and packages the BeiDou short messages into the data messages of the 376.1 protocol, and sends to the master station; the master station is connected with the master station-side BeiDou communication terminal, analyzes the received data messages, and stores, analyzes and displays the analyzed electric power data.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a system and method for collecting, transmitting and processing power data based on Beidou short message communication. Background technique [0002] At present, in the power monitoring system, communication methods such as power line carrier, optical fiber, and GPRS / CDMA are generally used, but these communication methods have two problems. The first problem is in remote areas such as mountainous areas and grasslands where residents are scattered. , these communication methods cannot be fully covered; the second problem is that natural disasters such as earthquakes and floods will cause these communication methods to fail to work normally. [0003] The Beidou satellite navigation system provides the short message function, which provides a solution to the coverage problem of the ground network. The maximum length of the short message communication of the Beidou satellite...

Problems solved by technology

[0005] 2) Beidou short message communication is unreliable communication. According to the statistical analysis results in "Beidou Short Message Communication Channel Performance Test and Statistical Analysis", the success rate of Beidou short message communication single data packet transmission is 95.5%, while In the process of power data collection, if any data packet is lost, the required power information may not be obtained;

[0006] 3) There is a limitation on the sending frequency of Beidou short messages. The civilian level generally sends a short message in 60s, but the communication and response time of the 376.1 protocol data message in the power user information collection system is far less than 60s. It will be considered as a communication timeout error by both sides of the communication

[0007] At present, a variety of applications have been proposed for Beidou short message communication, but none of them has disclosed an effective solution to the above three main problems
