The Research Of Intelligent Cloud Irrigation System Based On Raspberry Pi

In recent years,the world's irrigation technology is moving in the direction of precision,efficiency and manpower.The use of intelligent water-saving irrigation equipment has become a necessity for all countries and regions in the world to solve the water crisis and realize agricultural modernization.At present,China's agricultural irrigation methods are mainly based on ground irrigation,the irrigation method caused a huge waste of water resources,it must vigorously develop intelligent water-saving irrigation equipment.In order to improve the water efficiency of fine planting and realize the intelligent irrigation,this project designs and implements an intelligent cloud irrigation system based on Raspberry Pi II.The main contents are as follows:(1)By using Raspberry Pi II and soil moisture sensors,air temperature and humidity sensors,DC motor pump and its drive circuit and AD digital-analog conversion module,set up a low cost,high efficiency,stability Strong hardware system.(2)Finish the control programme and Web applications,and build a database,can let users to control the device view the relevant data bythe LAN or the Internet,so the device can become a "cloud" platform.(3)Finish a fuzzy algorithm control program.The algorithm programme has a two-dimensional fuzzy controller with correction factor.The input value is the change value of soil moisture and soil moisture.The output value is the PWM value of DC motor.The fuzzy control table is automatically generated on-line and can generate different control tables automatically according to different correction factors.(4)After the equipment finished,the equipment shall be tested in all aspects to meet the design requirements and objectives.The system combines the current more advanced Internet of things hardware and software technology,real-time collection of air temperature and humidity and soil moisture and other information,and stored in their own database,the system's own fuzzy computing controller can be based on data in the database output The appropriate amount of irrigation,so as to achieve the purpose.
