基于北斗短报文的智能电表数据通信方法研究

Research on data communication method of intelligent electricity meter based on Beidou short message

针对偏远地区电表数据采集稳定性较差的问题,提出一种基于北斗短报文通信的智能电表数据传输策略设计方案。该方案利用STM32F767微处理器和电流电压传感器来构建智能电表,采用NRF24L01模块与主站通信,且在此基础上进行系统化的硬件电路及软件设计。将电表的电力数据拆包后以北斗协议进行封装,使用北斗通信接口作为通信中介,由主站端接收北斗短报文,并对数据进行分析及重组。同时为了保证抄表的成功率,还设计了补包操作。实验测试结果表明,所提方法的抄表成功率为95%,能够保证远程数据采集与传输的可靠性。

Aiming at the poor stability of meter data acquisition in remote areas,a design scheme of intelligent electricity meter data transmission strategy based on Beidou short message communication is proposed in this paper.The scheme uses STM32F767 microprocessor and current and voltage sensor to build an intelligent electricity meter,uses NRF24L01 module to communicate with the master station,and carries out systematic hardware circuit and software design on this basis.After unpacking the power data of the meter,it is encapsulated with Beidou protocol,using Beidou communication interface as the communication intermediary,and the master station receives Beidou short message,analyzes and reo⁃rganizes the data.At the same time,in order to ensure the success rate of meter reading,a supplementary operation is designed.The experimental results show that the meter reading success rate of the proposed method is 95%,which can ensure the reliability of remote data acquisition and transmission.
