农田灌溉自动化控制系统的开发研究

Development of Automatic Control System for Irrigation

基于计算机技术、通讯技术、自动控制技术和现代农业技术进行系统集成与优化,研究开发了农田灌溉自动化控制系统。系统利用墒情传感器实时测量土壤墒情参数,通过无线网络传送给中央控制器,由控制计算机根据决策模型自动控制泵机的起停、管道阀门的启闭实现自动灌溉,为农田灌溉提供了一种新的节水设备。

The compositions, functions and operation of an automatic control system for irrigation is introduced in this paper. The technology concerned this system includes computer, communication, auto-control and modern agricultural. The system provides real-time monitoring for relevant parameters via sensors installed in field. All signals are delivered directly to a controlling computer through radio network. Start up and stop of pump unit, and open and close of solenoid valve is controlled automatically by computer with controlling and decision model, to realize automatic irrigation.
