Title: Design of intelligent classroom energy-saving systems based on power line carrier technique
Abstract: Power line carrier(PLC) communication technique,possessing the merits such as long distance transmission and no additional communication lines,is widely used in many fields.An intelligent classroom energy-saving system based on PLC is introduced,in which PLC transceiver IC LM1893 and microcontroller AT89C51 are used to realize the asynchronous serial multi-microcontroller communication via low voltage power line,and relevant hardware and software design are given in this paper.
