灌区灌溉用水量管理系统的研究与设计

基于GPRS无线通讯网络技术,提出了一种采用超声波明渠流量计、巴歇尔槽、液位传感器等原件构成的灌区明渠流量测量系统方案。系统可以及时的将传感器采集到的数据,通过GPRS模块无线传输给监控中心的上位机,上位机将接收到的数据进行分析和处理,进而实现上位机对明渠流量计和数据采集仪等仪器的控制。系统以较低的建设成本实现灌区测流管理的自动化和信息化,相对误差较小,能够满足明渠流量计算的精度要求,且实时性好,可靠性高。

Research and Design of Measurement System of Channel Flow Based on GPRS

Based on GPRS wireless network,a method of the channel flowing measurement system in irrigation area was presented,using GPRS Module,Ultrasonic Open Channel Flowmeter,Velocity Sensor,Liquid Level Sensor.The system can prompt the sensor data collected through the GPRS wireless module to the monitoring center of the host computer for analysis and processing.
