GPRS技术在自动抄表系统中的应用

针对自动抄表系统对数据传输可靠性和实时性的要求，提出一种基于新兴的通用分组无线业务GPRS(General Packet Radio Service)技术的自动抄表方案。该方案利用GPRS的Internet接入功能。在Internet上设置一通信服务器，负责中转主站与GPRS终端设备之间的通信，实现数据的实时采集和传输。详细介绍了系统构成和工作原理。该系统具有传输速率高，数据吞吐量大，通信实时、可靠等优点。该系统已在德州供电公司安装运行，效果良好。

Application of GPRS technology in automatic meter reading system

A new automatic meter reading system based on GPRS (General Packet Radio Service) ispresented to meet the demands for the reliability and real time performance of data communication. This scheme utilizes direct connection between GPRS network and internet, setting a server in In-ternet to take the charge of data communication between master station and terminal units for real-time data acquisition and transfer. Its structure and operational principle are introduced in detail. It is characterized by higher speed, great data throughput,teal-time performance and reliable communication. Its application in Dezhou Power Supply Company is proved successful and steady.
