Development Of Intelligent Control System For Precise Water Diversion In Irrigation Area

China is a large agricultural country that lacks water.There is a large demand for agricultural irrigation water,but the utilization rate of agricultural irrigation water in China is low.With the rapid development of Internet technology and sensor technology,the Chinese government has vigorously promoted the construction of modern agriculture,implemented smart agricultural transformation,and improved the automation of agricultural equipment.In recent years,in order to improve the utilization rate of agricultural irrigation water resources,the introduction of irrigation equipment from abroad has high prices and high requirements for operators.However,from the use of installed irrigation areas,there are low efficiency of equipment and water distribution control points problems such as islands.Therefore,it is of great significance to study the intelligent technology of water transfer in irrigation districts and develop an intelligent control system for precise water transfer in irrigation districts to improve the efficiency of water delivery in channels.The intelligent control system for precise water transfer in the irrigation area is mainly for open channel irrigation water diversion and water transfer applications.The data information of the channel gate terminal is collected in real time and transmitted to the cloud server through the GPRS communication network for calculation and processing.Water transfer instructions,and provide Android client mobile terminals and web pages with remote control,remote monitoring,irrigation area information query and other functions for auxiliary decision-making,intelligent water transfer and manual remote water transfer combined method.In the hardware design of the intelligent control system for precise water transfer in the irrigation area,the integrated intelligent gate for monitoring and control is used as the intelligent water transfer terminal.It is installed in the farmland canal system of the irrigation area.Irrigation;design solar power supply system to improve the stability and reliability of smart gate terminals working in the field.In the software system,the gate terminal data transmission method is designed.The Android Studio development tool is used to develop the Android mobile terminal.The ASP.NET and C # are used to develop the web terminal and the C / S upper control software,respectively,to achieve remote control,data query,and remote monitoring.And other functions.The cloud server uses Visual Studio as a development tool,bases on the channel operation mode and the simplified Saint Venan equations,establishes the middleware of the channel distribution control model for the channel operation control algorithm,and provides a Web service interface to implement customers Terminal software access to gate information data.Based on SQL server 2012,a database containing irrigation district personnel,equipment,and water information was developed.The intelligent control system for precise water transfer in irrigation areas has been promoted and applied in several irrigation areas.The actual results show that the control system has realized the use of information and digitalized precise water transfer in irrigation areas.
