摘　　要：针对传统的农田自控系统存在的不足,采用GSM网络技术和FSK调制方式开发出了农田滴灌智能监控系统。该系统由数据采集子系统、决策支持子系统和自动控制子系统三大功能模块共同组成交叉式的三级网络结构,采用基于土壤湿度临界值、CWSI指数、作物生长模型和Penman-Monteith蒸散量模型进行智能化决策,实现了基于GSM/FSK的农田环境参数自动采集、灌溉智能决策与监测控制等功能。系统在新疆兵团农六师111团70hm2覆膜滴灌棉田上示范应用,效果良好。Because of the drawback of traditional automatic control systems, the system of intelligent monitor and control for drip irrigation field was designed and applied. This system consists of the networks among these subsystems such as data collection subsystem, decision support subsystem and automatic control subsystem. Its intellectualized decision system was based on the soil moisture content suitable for the growing crop and crop water stress index（CWSI） and the models of crop growth and the reference evapotranspirations（ET0） calculated by the Penman-Monteith. Therefore, through the global system for mobile communication（GSM） and frequency shifting keying（FSK）, the functions of data collection and intellectualized decision and control have been realized. Nowadays the system has been applied to the 70 hm^2 cotton field at Farm 111 and run very well in Xinjiang.
