摘要
本文简要介绍了GPRS技术的原理和特点,提出了一种基于GPRS网络的远程无线分布式测控系统的构建方案,系统以MSP430F149为终端的MCU,对如何接入GPRS网进行了具体说明,最后分析了系统数据传输的安全性。
This paper introduces the technical theory points of GPRS firstly,then brings forward a project used to build a kind of tele-wireless distributed monitor&control system based on GPRS?This project adopts MSP430F149 as MCU,narrates partically the framework of the system,and expatiate on the approtch how to carrying out each technical point concretely,including the design of hardware of the equipment,the design of software,the protocols and commands which will be used,and the design of building monitor&control center?And finaly,the security of data in wireless transmission is also discussed.
