基于无线传感器技术的水文监测系统设计

Design of hydrological monitoring system based on wireless sensor technology

针对水文信息监测区域广、监测参数多以及传统水文监测系统所存在的问题,依据监测点的特点,利用ZigBee和GPRS技术,开发了基于无线传感器技术的水文监测系统,实现了水文参数的无线传输。ZigBee技术具有自组网、成本低、耗能少等特点,可以很好地解决水文监测系统设计中存在的问题。系统可将传感器采集到的温度、pH值和水位等参数通过ZigBee网络无线传输到监测中心,再通过GPRS模块的短信通信功能将报警信息发送至用户手机上。

In the light of wide area, multiple hydrological parameters and the problems existed in conventional hydrology moni-toring system, and aiming at the characteristics of monitoring points, a hydrological monitoring system based on wireless sensor technology is developped by Zigbee and GPRS, so as to realize wireless transmission of hydrological data. Zigbee has advantages of ad hoc network, low cost, less energy consumption, etc. The system can transmit the collected data such as temperature, pH and water level to central station by Zigbee, and then the central station can send the alarm information to the cell-phones users by SMS function of GPRS.
