一种载波自动抄表系统的通信解决方案

A Communication Solution of Automatic Meter Reading System

针对目前低压电力载波通信中存在的信道阻抗、信号衰减、噪声干扰等质量问题,依据扩频通信原理,提出了应用CDMA直接序列扩频的方法设计一种电力载波自动抄表系统的方法.通过对同步过程的搜捕阶段和跟踪阶段的分析,证明了本系统所采用的通信方式具有高抗干扰性及低误码率.

In view of the problems of rout impedance,signal decadence and noise interaction which lie in LV power line communication and based on the theory of spread spectrum communication technology, the author proposes an approach to design an automatic meter reading system based on the CDMA direct sequence spread spectrum. This method has more merits by analyzing the searching and catching stage and the tracking stage.
