基于PRO-F土壤湿度传感器的干旱地区自动喷灌系统研究

Research of Automatic Sprinkler in Arid Regions System Based on PRO-F Soil Moisture Sensor

应用基于频域反射法(FDR)而进行研发的产品PRO-F型土壤湿度传感器自动检测到的土壤的湿度,并由智能仪表采集监测到的控制信号通过数据总线传输给上位机组态软件MCGS,通过PID运算完成对调节阀开启程度的控制,最终达到使土壤湿度保持在一个满足作物需求的合理范围内,再利用喷灌技术,很好的解决了干旱地区农作物节水灌溉的问题。

The PRO-F-type soil moisture sensors detect soil moisture automatically, and the control signal collected by intelligent instrument through the data bus transfer to the PC configuration software MCGS. Ultimately, it makes the soil moisture meet crop needs to maintain a reasonable range. There is a good solution about water-saving irrigation problems of crops in arid regions.
