摘要
提出一种基于无线GPRS通信网络、GPS和GIS技术的消火栓在线检测定位系统。介绍其系统构成、硬件设计、工作原理。系统通过机械压力超限检测模块,在无源下实时检测消火栓压力状态,水压超限时唤醒控制核心,使其读取电子水压传感器数值,将水压值、预置地址代码和差分坐标信号发送至监控中心,实现消火栓的在线监测和定位。在线监测系统实现了消火栓精确定位,误差在30cm内,提高了对发生突发事件的预报率。
An online monlior and location system of fire hydrant based on GPRS, GPS and GIS was put forward. The system construction, hardware design, and working function were in- troduced. By mechanical pressure overrun detection module, the system can real-time monitor the hydrant pressure under passive condition, and awaken the control core when water pressure overruns, which will read the electronic pressure sen- sor values, and send the water pressure value, preset address code and the differential coordinates signals to the monitoring center, to realize the online monitoring and positioning of fire hydrant. The online monitor system achieved the accurate loca- tion of hydrant, with the error under 30 cm, and improved the emergency prediction rate.
