灌溉渠道远程数据采集平台设计

为促进灌区信息化建设,针对灌溉渠道数据信息有线监测系统面临的布线复杂、施工及维护成本高等问题,在分析灌溉渠道数据采集节点分布特点的基础上,结合Zig Bee近距离通信技术和GPRS远距离通信技术各自的优势,设计了一款数据测量终端和用于远程数据传输的遥测终端。测量终端以一定采样频率获取监测区域水位、流量、水质等信息,通过测量终端将传感器数据以无线信号形式向遥测终端传输,遥测终端完成Zig Bee网络数据收集并远程传输至监控中心。利用测量终端和遥测终端构建了渠道数据监测网络,可用于灌溉渠道水位、流量及其它重要参数信息的监测。现场实际测试运行效果表明,该平台采用无线传输方式,实现了渠道流量的数据采集、传输及显示功能,并能够实现渠道多数据信息的采集及远程数据传输。

Design of remote data acquisition platform for irrigation canal

Wired information monitoring system for irrigation canal faces the problems of complex arrangement of wire and high cost of construction and maintenance. In order to promote the construction of irrigation informatization, based on the analysis of the distribution characteristics of data acquisition nodes in irrigation canal, in combination with the use of the advantage of ZigBee technology and GPRS technology, a data measurement terminal and a remote data transmission terminal to construct a data monitoring platform for irrigation canal are designed. The measurement terminal obtains the information of water level, discharge and water quality of the monitoring area with a certain sampling frequency, and the sensor data are transmitted to the remote data transmission terminal by wireless signal, which completes the ZigBee network data collection and transfers the collected data to the monitoring center. The data monitoring network built by the data measurement terminal and the remote data transmission terminal can be used for monitoring water level, discharge and other important parameters of the irrigation canal. Through the field test, the function of collection, transmission and display of discharge data are realized. By this method, multi data acquisition and remote monitoring for irrigation canal are realized.
