基于GPRS和电力载波通信的远程数据采集系统研究

摘要

A remote data acquisition system was designed by using the technology of GPRS and electric power carrier com-munication.The system was composed of user terminal,data concentrator,communication subnet,220 V power line network,moni-toring center. The characteristics of the electric power carrier communication channel were analyzed. The design principle of elec-tric power carrier communication was introduced.The time slice communication protocol was adopted to realize the communication between these modules of electric power carrier communication. Testing results show that the system has advantages of low cost, convenient to be installed.%利用GPRS技术和电力载波通信技术设计了远程数据采集系统.该系统由用户终端、数据集中器、通信子网、220 V电力线网和监控中心组成.分析了电力载波通信信道的特性,介绍了电力载波远程采集系统设计原理,采用时间片通信协议来实现电力载波通信模块之间通信.测试表明:该系统具有成本低廉、安装便捷等特点.
