摘要
提出了一种新的照明线数据通信方法 ,载波信号通过锁相环把模拟信号转换成数字信号 ,然后通过匹配检测的方法还原出原代码 。
A new method of data communication on power wire is developed. When a carrying wave signal through the integrated circuit phase loked loop, it changes a simulate signal into a data signal, then the data signal through matching detector acquires a based band signal. The fast realization method can be given through the single chip microcomputer. This method has high anti disturbance capability. The results of the study sow that this method can be applied in power wire communication and it has the good immunity to interference and can be realized easily.
