本文介绍了一种地下水位实时监测系统的设计方案。该系统主要包括信号采集、无线模块、数据处理及存储三部分。压力传感器获得的信号进行调理放大,送入主控制器LM3S615进行A/D转换等处理,然后通过无线通信模块PTR8000发送到室内监控室。PTR8000接收端接收到数据后通过串口RS232发送到上位机,人机界面通过LabVIEW软件实现,可以对数据进行处理、显示及存储等。该方案对提高监测系统的便携性,降低成本和能耗,有一定的参考价值。
This paper introduces a design scheme of real-time monitoring system of groundwater level. The system includes signal acquisition, wireless module, data processing and storage of three parts. Pressure sensor signal conditioning to enlarge, into the main controller LM3S615 for A / D conversion and other processing, and then through the wireless communication module PTR8000 sent to the indoor monitoring room. PTR8000 receiver receives data through the serial port RS232 sent to the host computer, man-machine interface through LabVIEW software, data processing, display and storage. The program has some reference value to improve the portability of the monitoring system, reduce the cost and energy consumption.
