基于GPRS的通信技术在远程抄表中的应用

Application of GPRS in remote meter reading system

随着当今电网自动化程度的提高,远程抄表已成为提高现代化电网供用电管理水平的重要手段。针对远程抄表系统对数据传输可靠性和实时性的要求,提出了一种基于新兴的通用分组无线业务GPRS技术的远程抄表方案。介绍了GPRS的网络结构和协议以及GPRS的数据传输,重点论述了基于GPRS技术的远程抄表系统的框架、工作原理以及其软件设计,并给出了一种双模式通信方式的远程抄表系统设计方案。随着通信技术的发展,这种双模式通信方式一定会有广阔的发展前景。

With the enhancement of electrical network automationy, remotemeter reading has become the important way to improve the electricity management level of modernized electrical network. A new meter reading system based on GPRS is presented to meet the demands for the reliability and real time performance of data communication. This paper introduces the GPRS network architecture and the protocol, as well as GPRS data transmission and emphasis on the frame, operating principle and design of software in remote meter reading system based on GPRS technology, and puts forward a design plan of remote meter reading system based on double-mode communication. It is characterized by higher speed, great data throughtput,real-time performance and reliable communication. Along with the development of communication, the double-mode communication certainly has a broad foreground.
