基于GSM/GPRS的无线监控系统设计

Design of a Wireless Monitoring System Based on GSM/GPRS

介绍了以嵌入式监控终端、用户手机和远程监控中心计算机构建的无线监控系统的设计。着重论述了无线模块在嵌入式系统中的应用方法。介绍了通过无线模块发送和接收短消息以实现对现场设备的监控方法;分析了如何依靠无线模块经过GPRS网络与接入Internet的固定IP计算机建立连接并进行通讯。结果表明,在现有的移动通讯网络覆盖的区域,利用本系统可以完成对现场设备的在线数据采集、远程无线数据传输与监控。在露天场所、野外、移动作业环境或有线网络无法接入的地点建立数据采集与监控系统时,基于GSM/GPRS网络的嵌入式远程无线监控解决方案具有突出的优势。

The design of a wireless monitoring system composed of embedded monitoring terminals, users＇ cell phones and a remote computer as the monitoring center is introduced. The method of application of a wireless module in embedded systems is emphatically discussed. The method of monitoring equipments in the field by using the wireless module to transmit and receive short messages is introduced; the process of establishing a link between the wireless module in the GPRS network and the fixed IP computer in the Internet and communicating each other are analyzed. The result shows that, in the area where the GSM/GPRS network is available, the system can accomplish the data acquisition on line, wireless remote data transmit and monitoring for the equipments in the field. The solution of embedded wireless remote monitoring has a prominent advantage when constructing monitoring systems in the open air, field place, mobile operation condition or wherever the network cables can not reach.
