摘要
利用载波通信进行电度表数据的传递,一直以来是人们研究的热点。其最大困难是如何在复杂电力环境下克服通信干扰问题。利用最新的国产电度表专用抄表载波通信芯片PL3201,设计了新型的电度表抄表系统,分别给出了系统的工作原理、硬件设计以及部分关键软件流程图。该系统在抗干扰、串扰等多方面都有较好的表现。
Transferring readings of power meters by adopting cartier communication through power lines is always the topic of general interest The most difficult problem in implementation is how to overcome the communication interference under complicated environment of power grid. By adopting the latest product PL3201, the dedicated IC for reading power meters through cartier communication, a novel reading system is designed. The operational principle, hardware design and partial critical software flowcharts are given. The system offers better performance in anti-interference and anti-cross talk.
