Design and application of precise wireless control equipment of water fertilizer irrigation in orchard
摘要
Abstract
According to complex environment in most mountain orchards and urgent demands of centralized management for zone control irrigation in large area,a low-power consumption and low-cost irrigation control equipment was developed. The con-trol algorithm combining PID control,fuzzy control and grey prediction control equipment is embedded in the equipment,which can effectively solve the time delay phenomenon,predict water requirement of fruit tree,and achieve the precise control of the irrigation. The low power microcontroller and bi-stable solenoid valve are chosen to avoid channel congestion. The wireless com-munication mode combining GPRS for long distances with NRF2401 for short distance is adopted,which can open the solenoid valve on time. The running test results show that,in comparison with conventional control systems,the overshoot of the system is reduced by 22.5% and the response time of the system is decreased by 28.2%. The system has high response speed,good real-time performance and reliable wireless communication,and has improved the water fertilizer irrigation effect.关键词
