基于计算机网络控制的智能喷灌系统应用研究OA

In order to achieving the accurate control for water content in plant roots,this Intelligent Sprinkler Irrigation System was designed based on ZigBee.The relative correlation coefficients were calculated among surface moisture con-tent variation,average temperature,sunshine length and root moisture content variation respectively.Surface moisture content variation was taken as independent variable,and the relationship between surface moisture content variation and root moisture content variation was achieved based on linear fitting.The relationship between sprinkler valve control sig-nal and sprinkler irrigation flow,and then the model between sprinkler valve control signal and surface moisture content variation was found.The system work flow was designed,the precise control for root moisture content variation was achieved.The accuracy for surface moisture content monitored by this system was tested,and stability control accuracy for the root moisture content was test,the result showed that this system had good working performance.
