摘要
开发了多路并行工频通信系统。该系统主要由子站系统和用户终端装置两部分组成,给出了各部分的关键硬件电路及其连接关系。研究了多路工频通信系统下行信号发送和接收、上行信号发送和接收的关键技术,并运用三相信号并行传输、单相6路信号并行传输及不同馈线信号并行传输来提高系统信息传输速率。设计了系统终端地址及与DL/T698-41等标准兼容的工频通信协议。多路并行工频通信系统速率较传统单路工频通信系统有明显提高,能更好地满足用电信息采集系统的需求。
A kind of multi-channel parallel power-frequency communication system is developed,which contains mainly the substation system and the user terminal equipment. Key hardware circuits and their connections are given. The key technologies of downlink signal transmission/detection,uplink signal transmission/detection are researched. Three-phase signal parallel transmission,single-phase six-channel signal transmission and multi-feeder signal parallel transmission are applied to enhance the transmission rate of system data. The terminal address code and communication protocol compatible with DL/T698-41 standards are designed. The multi-channel parallel communication system transmits data much faster than the single- channel communication system does,which satisfies the demands of electric energy data acquisition system.
