The intelligent campus energy-saving system research based on power line carrier

Abstract

This paper introduces a power line carrier technology based on MCU-51 of the campus power saving control system's working principle and structure; At the same time, it introduces direct sequence spread spectrum and half duplex asynchronous modem PL2102 carrier chip, which are used in the power line carrier application system can realize the classroom management and control of the electric light; With PL2102 are given for the control of electric light's basic principle and the method how to realize through software and hardware, along with its design schematic diagram. © Springer-Verlag Berlin Heidelberg 2013.
