摘要
为了节约水资源,同时满足作物生长各个时期对水分的不同需求,需要建立能检测土壤水分信息和检测点的位置信息,并能自动控制执行机构的灌溉系统。应用虚拟仪器开发平台LabVIEW和数据采集卡结合各种传感器和GPS定位系统,实现了土壤水分的实时定位采集,并对获取的信息进行分析处理,并利用GSM把采集数据远距无线传输到服务器,在服务器端结合模糊控制技术,控制灌溉执行机构从而实现精确的水灌溉。
In order to save water and meet the water demand of crops in different growth periods, an irrigation system is required to detect the information of soil moisture, locate the sample points with GPS and control the executing machine. Virtual Instruments graphical programming LabVIEW, data acquiring board and varieties of sensors were used to acquire the soil moisture and orientation information of the sample points at real time. The acquired data were analyzed and the data were transmitted with GSM to a remote server. Combined with fuzzy technology on server side, the irrigation executing machine was controlled to implement the precision irrigation.
