摘　　要：针对我国新疆地区土地干旱,水分下渗和蒸发比较严重导致灌溉过程中水分流失的问题,研制出一款根据土壤湿度传感器数据和作物需水量进行决策,实现智能灌溉的阀门控制器。该控制器以STM32单片机为控制核心,采用太阳能供电的方式,控制器包括单片机控制电路、土壤湿度采集电路、太阳能充电控制电路、阀门驱动电路、无线通信电路、阀门状态反馈电路。控制器通过土壤湿度传感器采集的数据进行灌溉决策,在土壤含水率低于作物最适宜生长值下限时开启阀门,当土壤含水率达到田间持水量时关闭阀门。农民能通过手机APP远程获取土壤湿度数据和阀门开关状态信息,并能远程控制阀门进行灌溉。经实验分析论证,该控制器运行稳定,能将土壤含水量控制在合适的范围。In order to solve the problem of water loss in the process of irrigation due to the drought and serious water infiltration and evaporation in Xinjiang,a valve controller is developed to realize intelligent irrigation based on the data of soil moisture sensor and crop water demand.The controller is based on STM32 single-chip microcomputer and adopts solar power supply.The controller includes single-chip microcomputer control circuit,soil moisture collection circuit,solar charging control circuit,valve driving circuit,wireless communication circuit and valve state feedback circuit.The controller uses the data collected by the soil and humidity sensor to make irrigation decision.When the soil moisture content is lower than the optimal growth value of crops,the valve is opened,and when the soil moisture content reaches the field capacity moisture content,the valve is closed.Farmers can obtain soil temperature and humidity data and valve switch status information remotely through mobile APP,and can remotely control the valve for irrigation.The experimental analysis shows that the controller is stable and can control the soil moisture content in a suitable range.
