摘要
介绍一种基于51单片机的电力线载波技术的校园节电控制系统的工作原理和结构。直序扩频半双工异步调制解调器PL2102载波芯片,通过电力线载波应用系统实现教室电灯的管理和控制,给出用PL2102对电灯进行控制的基本原理、软硬件实现方法及其设计原理图。
This paper introduces power line carrier technology campus energy-saving control system working principle and structure based on 51 MCU. 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. It can realize the management and control of classroom light, the basic principle of using PL2102 control electric light and the method of software and hardware are given. The design schematic diagram also are proposed.
