摘　　要：为节约温室大棚内作物生长所需的人力资源和水资源,设计一款高效、便利并且可以实时远程操控的智能喷灌系统。系统利用湿度传感器对当前土壤的湿度进行监测,并通过变送后,输出标准的RS485信号和4~20 mA标准电流信号,以实时显示土壤的湿度及自动控制水泵动作,实现自动浇灌。同时,也可以使用手机APP软件,远程控制Wi-Fi模块上的继电器,继而控制水泵动作,实现对大棚内作物的喷淋和灌溉,满足作物生长对水分的需求。In order to save the human resources and water resources needed for crop growth in the greenhouse, an efficient, convenient and real-time remote control smart sprinkler irrigation system was designed. The system uses the humidity sensor to monitor the current soil humidity, and through the transmission, the standard RS485 signal and 4~20 mA standard current signal are output to display the soil humidity in real time, and automatically control the action of the water pump to realize automatic irrigation. At the same time, we can also use the mobile phone APP software to remotely control the relay on the WiFi module, and then control the action of the water pump to achieve spraying and irrigation of crops in the greenhouse to meet the water needs of crop growth.
