煤田火灾无线远程监测预警系统设计

摘要

In view of problems that forecast range is small, work load of installation and maintenance is large, and real-time monitoring and early-warning cannot be provided existed in traditional temperature monitoring systems of coalfield fire area with manual detection way, a wireless remote monitoring and early-warning system of coalfield fire based on technologies of ZigBee, GPRS and Internet. Through wireless temperature measuring terminal and gateway which are set at each monitored point, the system sends collected temperature signal to GPRS network, and the signal is accessed into Internet network through SGSN and GGSN. Then server of upper computer monitoring center of the system connects with Internet network and displays the monitoring interface by web page, so as to realize function of remote monitoring and early-warning for coalfield fire area. The field test result showed that the system solves problem of remote and real-time monitoring and early-warning for coalfield fire and has certain practicality.%针对传统的煤田火区温度监测系统人工检测方式存在预测预报范围小,安装、维护工作量大,不能提供实时监测和预警等问题,设计了一种基于ZigBee技术、GPRS技术和Internet技术的煤田火灾远程监测预警系统.该系统通过设立在各个监测点的无线测温终端和网关将采集的温度信号发送到GPRS网络,经SGSN和GGSN接入Internet网络；上位机监测中心服务器再与Internet网络相连,以网页的形式显示监控界面,从而实现了煤田火区温度远程监测预警功能.现场试验结果表明,该系统解决了目前煤田火灾远程实时监测预警的难题,具有一定的实用性.
