Research And Development Of Agricultural Water And Fertilizer Integrated Intelligent Monitoring System

With the continuous development of science and technology,traditional irrigation and fertilization technology has not met the requirements of agricultural development.Agricultural modernization has become the top priority of agricultural development today and even in the future.Modern agricultural technology and agricultural equipment will become an important means to increase agricultural productivity and ensure sustainable agricultural development.Under such background of agricultural development,this article based on the study of the integrated irrigation system of water and fertilizer in Israel,and focuses on the production process of irrigation and fertilization,and developes a set of intelligent monitoring system of agricultural water and fertilizer integration,and carried out the following aspects of research.In view of the shortcomings of the water and fertilizer concentration control strategy based on the traditional PID control,this article proposes the water and fertilizer concentration control strategy based on the fuzzy neural network PID control.The control strategy is verified and analyzed by simulation comparison test and actual test respectively,the simulation results and test results show that the fuzzy neural network PID has higher control accuracy for water and fertilizer concentration,smaller overshoot and shorter adjust ment time compared with the traditional PID control.The integrated intelligent monitoring system of water and fertilizer is mainly composed of an integrated water and fertilizer machine,embedded controller and monitoring center.The integrated water and fertilizer machine provides the hardware foundation for the system's irrigation and fertilization.The monitoring center and embedded controller complete the irrigation and fertilization process by controlling the integrated water and fertilizer machine.Data interaction between monitoring center and embedded controller is conducted through TCP communication.Embedded controller adopts STM32+ ?COS-II embedded architecture to accomplish multi-task management,achieve data acquisition,irrigation and fertili zation,TCP communication tasks,improve the real-time and stability of the system.The monitoring center independently developed a set of upper monitoring software on the Visual Studio 2015 platform with C# language,which can realize system operation monitoring,historical data query,real-time curve display,fault alarm and other functions.By referring to the.dll control generated in Matlab to achieve the precise ratio of water and fertilizer concentration;and through the combination with database to complete the execution of irrigation task,the management of irrigation formula,the real-time monitoring of irrigation process and the storage and processing of irrigation data.The final test results show that the integrated intelligent monitoring system of water and fertilizer developed in this article has the characteristics of stable operation and quick response,in the process of irrigation and fertilization,it can accurately provide water and fertilizer for crops,meet the requirements of intelligent irrigation and fertilization,and realize the precise control of water and fertilizer concentration.It is of great significance in increasing crop yield and saving resources.
