使用单片机实现GPRS通信小系统的研究

Realization of GPRS Small Communication System Based on Single-chip Microcomputer

提出用单片机控制GPRS(通用分组无线电业务)模块进行无线通信。本系统属于远程电力终端抄表的一个模块。主要研究以单片机为中心的小型GPRS通信方案。在GSM(全球移动通信系统)和GPRS网络较好的情况下,本系统能够较稳定地联入无线网络,与手机、计算机服务器等通信,通过GPRS方式传递数据,由手机设置读取通信参数或由计算机传递数据等,具有很高经济价值。

This paper proposes a method of using a single chip microcomputer to control the GPRS module to realize wireless communication. The system is part of the long-distance electric metric terminal. It mainly studies the scheme of mini-GPRS communication system which takes MCU as core. In the case of GPRS and GSM network being good, the system can connect to the Internet and other network. It can communicate with a mobile phone or a computer. It can transmit data over GPRS network and be read or written communication parameters by a mobile phone. It has high economic value.
