摘要
利用原有的低压电力网进行数据传输与控制 ,可广泛应用于家庭和办公室的智能化 ,经济方便。本文设计一种适应我国电网特性的通用型电力线数据传输系统 ,该系统为半双工、异步模式 ,采用双音多频调制 ,数据传输率 4 0bps。
Utilizing the low-voltage electrical network to carry out data transmission and control,can be applied extensively to the intelligentization of the home and official business,and it is economical and convenient.This paper describes a universal data transmission system base on power line that adapts to the characteristic of the electrical network in our country。This system is half-duplex, asynchronous and introducing FM by DTMF.The rate of data transmission is 40bps.The practical application indicates the performance of this system is good.
