摘要
以通用电力线载波通讯芯片LM 1893为核心 ,以AT89C5 1单片机为主控单元 ,建立一个点对点的电力线载波通信系统 ,在电力线上实现数据及话音的传输。
Using a carrier-current transceiver chip (LM1893, produced by the National Semiconductor Corporation) and a single chip microcomputer (AT89C51, produced by the Atmel Corporation) a data and voice communication system is established. Hence the transmission and reception of the data or voice on the power line from one place to another one are realized.
