Design of Intelligent Water-Saving Irrigation Control System Based On Rainfall Forecast

Abstract

Based on the current research on lack of water resources and irrigation in China, on the basis of this paper puts forward a intelligent water-saving irrigation system based on rainfall forecast, designed with sensors and the wireless communication module of sensor nodes, the smart irrigation control system, introduced the local weather forecast, the water demand for crops is analyzed, Determine the optimum soil moisture during the growing season and extend irrigation time; Considering whether it will rain in two days, by the matlab fuzzy logic toolkit, designed the fuzzy controller and fuzzy controller, the rainfall tests show that system can independently according to the crop water requirement and weather forecast information to drive the solenoid valve to complete intelligent irrigation, at the same time send farmland environmental information remote control center to set, broke through the regional restriction, It is of great significance for farmers to check farmland soil moisture information to improve the utilization rate of water resources in China.
