基于PL2000模块的电力线扩频载波数据通信系统

A New Power Line SSC Data Communication System Based on PL2000 Modem

针对远距离监控的通讯问题，设计了以 ＰＩＣ单片机为主控制器，以电力线为传输媒 质，基于ＰＬ２０００模块的扩频载波数据通信系统．给出了系统功能框图和程序框图，分析了各组 成部分的电路．现场运行表明，该系统可靠性强，便于组网，有效地解决了设备网络化管理的通 讯问题．

View of the communication problem on far distance monitor, a new spread spectrum carrier data communication system is designed, which is composed of a PIC microcontroller acting as the main controller, power line as the communication medium, and IC-PL2000 as the physi- cal and data link layer. This paper gives the system diagram and program diagram, and analyzes circuit of every part. Practical operating shows that the system has high reliability and is easy to make network, so as to solve the communication problem of the network management.
