为实现三江平原灌区地下水位数据的实时采集和监控，设计了基于无线传输的灌区水位监控系统。数据采集终端使用超声波水位传感器对地下水位进行实时监测，使用 GPRS 无线通讯技术实现水位数据的远距离传输；水位监控中心接收、处理、存储并实时显示水位数据，同时绘制出水位变化折线图。试验结果表明，系统测量误差介于0．1～0．5cm 之间，能完成对灌区地下水位的实时监测，运行十分稳定，为当地政府部门合理开发灌区地下水资源提供了宝贵的科学依据。

In order to monitor and gather the groundwater level data of irrigated land area in Sanjiang Plain in real time , a wireless based water level monitoring system is designed .Ultrasonic sensor is used as part of the terminal to collect and monitor the water level in real-time.GPRS networkis utilized to transport the water level data from terminals to the moni-toring center .Water level data are then processed , stored and displayed along with the automatically generated figures and curves about water-level changes.The experiment result shows that the measurement error is between 0 .1 cm and 0.5cm.The system proofs to be capable of monitoring the water level of irrigated land area in real -time while work-ing in a very stable condition .And the system is also valuable of providing scientific evidence for the local authorities to wisely and rationally develop the groundwater resources in the irrigated land area .
