Development Design And Implementation Of Lycium Chinense Intelligent Irrigation System Based On JFinal

At present,there is a serious shortage of water resources in China.Compared with other countries in the world,the per capita water resources are seriously insufficient,and the northwestern region of China is even more frequent in drought.The development of agriculture is inseparable from water,but in most areas due to backward irrigation technology,the utilization rate of water resources development is low and only 40% to 50%,and the effective utilization coefficient of irrigation water is only 0.4.As a local specialty,Lycium chinense is one of the indispensable economic sources in Ningxia.Ningxia is located in the northwestern part of China,with little rainfall and arid climate.But the growth of Lycium chinense needs suitable water.Nowadays,the application of intelligent irrigation system plays an important role in improving the utilization rate of agricultural water resources and increasing crop yield.Aiming at the above problems,this paper designs Lycium chinense and designs a set of intelligent irrigation system based on JFinal framework.The overall structure of the irrigation system is based on the three-tier architecture of the Internet of Things.The environmental data collected by the sensor is sent to the server through the wireless network and stored in the database.After logging in the irrigation center system in the browser,the user can realize remote monitoring and irrigation control of Lycium chinense.Among them,the irrigation center system is in the application layer of the three-layer architecture of the Internet of Things.It is the control center of the irrigation system and the main research content of this paper.The irrigation center system adopts B/S architecture,MySQL database and Undertow server,and integrates Java Web technology.It is an all-round development based on JFinal framework.According to the functional requirements of the system,each functional module is designed in detail,including user login module,information query module,data display module and irrigation control module.The system mainly uses AJAX and WebSocket in the data exchange between front and back of the Web.The system's data monitoring uses the WebSocket protocol to enable long-term communication between the client and the server,enabling the server to initiate data updates and push the updated data to the client.The system's intelligent irrigation is based on fuzzy control theory.According to the optimal soil moisture during the growth period of Lycium chinense,the irrigation time of Lycium chinense was obtained by taking soil moisture deviation and soil moisture deviation change rate as input.Finally,this paper tests the system.The test results show that the JFinal framework is powerful,and the intelligent irrigation system based on JFinal can run stably,with good expansibility and compatibility,which is suitable for remote monitoring and irrigation control of Lycium chinense.
