摘　　要：利用通信可靠的工频通信技术实现基于低压电力线的远程自动抄表过程,系统采用上、下位机结构,用GSM等公共网络实现上、下位机之间的通信。上位机(PC机)用于数据管理,下位机 (MCU)用于数据采集和对上位机指令的执行。详细讨论下位机核心集中器和终端通过低压电力线实现信号收发的原理及过程,给出了相应的硬件电路拓扑图和程序流程图,并对系统特点进行了分析。Realize the remote and automatic meter reading course based on reliable low voltage power line power frequency communication（PLPFC）. The system based on two parts：one is PC, the other is MCU. We could realize the communication between PC and MCU by such networks as GSM,etc. PC is the data administrative center, MCU is used to gathering the data and to transmit PC＇s instruction. Concentrator is the kernel of MCU, the communication in MCU is realized through low voltage PLPFC, that is, concentrator gathering the meter＇s reading from meter reading unit（MRU） or transmitting the PC＇s instruction to MRU through low voltage power line. The principle and course of realizing the communication between concentrator and MRU through low voltage PLPFC has been described in detail in the article, and the corresponding topology of hardware circuit and flow chart of procedure has been provided too. We analysed the system＇s characteristic in the end of the article.
