The Design And Implementation Of Remote Agricultural Irrigation System Based On Wireless Terminal

The increasing shortage of water resources has become a global problem,saving water and high efficient water use is becoming a requirement for human survival and development.China is one of the poor countries in the world,and the distribution of water resources is very uneven.With the growing population and urban development,the contradiction between supply and demand of water resources has become increasingly fierce.As a big agricultural country,agricultural water in China occupy the country’s total 70% of water,agricultural drought and water shortage situation is irreversible.At the same time,in agricultural irrigation,there is a low irrigation efficiency,waste of water.Under this background,through the modern irrigation technology transformation of traditional agricultural irrigation,precision irrigation can not only improve the utilization of water resources,slow down the trend of increasingly scarce water resources,but also increase crop yield,improve the income of the farmers.Based on embedded system,combined with network communication technology and wireless transmission technology,the research of agricultural remote automatic irrigation system is carried out.The purpose of this paper is to construct a system which can control the agricultural irrigation remotely,and the main work of this paper includes:(1)Based on an embedded system which is composed of arm and Linux,this system can not only realize accurate control of the valve switch quantity to achieve scientific and rational use of water for irrigation,and is very easy to achieve the function expansion,add soil moisture,rainfall detection system,in a step to achieve a fully automated smart irrigation system.(2)The centralized control server based on the B/S architecture is adopted to implement centralized management on the front end control points,which is convenient for the expansion and management of the front end control points.(3)The use of 3G technology provides high-speed,real-time advantages,breaking the constraints of agricultural irrigation space and distance of previous transmission mode.With the remote control and real-time video transmission,the system can achieve the perfect combination of real-time video and control,users can more intuitively observe control results and site of the actual situation.
