【摘要】：针对传统温室大棚灌溉智能化和自动化水平低的问题,采用无线传感器网络WSN技术设计了智能温室大棚自动定点喷灌系统。系统主要由监控中心上位机、多个温湿度监测和电磁阀控制节点、密封储水罐压力监测节点、充压机和水泵控制节点组成。通过温湿度传感器获取土壤表层的温度和湿度数据,并经过ZigBee网络将该节点ID和数据打包实时发送至监控中心上位机,一旦监测到的湿度低于设置的阈值时,会控制对应该区域的电磁阀开启进行喷灌,同时控制充压机保持储水罐内的压力为恒定值。试验表明,该系统能准确获取土壤表面的温湿度数据,实现了整个温室大棚的定点喷灌和密闭储水罐的自动补水功能。
[Abstract]:Aiming at the problem of low level of intelligent and automatic irrigation in traditional greenhouse, the automatic fixed-point sprinkler irrigation system of intelligent greenhouse was designed by using wireless sensor network (WSN) technology. The system is mainly composed of the upper computer of the monitoring center, several control nodes of temperature and humidity monitoring and solenoid valve, the pressure monitoring node of sealed water storage tank, the filling press and the control node of water pump. The temperature and humidity data of the soil surface are obtained by the temperature and humidity sensor, and the node ID and the data are packaged and sent to the upper computer of the monitoring center through the ZigBee network. Once the humidity monitored is below the set threshold, Sprinkler will be controlled to open the solenoid valve in the appropriate area, while the filling press will be controlled to keep the pressure in the tank constant. The test results show that the system can accurately obtain the soil surface temperature and humidity data and realize the automatic water replenishment function of the fixed point sprinkler irrigation and the closed water storage tank in the whole greenhouse.
