Design And Implementation Of Soil Moisture Forecasting And Early Warning Platform

Drought and flood disaster is one of the most important factors that affect agricultural production.The frequent occurrence of disasters has affected crop yields in some areas of our country,which has seriously restricted the development of agricultural economy.The development of precision irrigation technology and accurate prediction of crop soil moisture has been the focus of researchers.At present,some scholars have carried on the corresponding research in the soil moisture early warning system,but it is not mature enough to predict the change of soil moisture and to judge when the crops need water.The traditional technology of soil moisture forecast can provide some help for the irrigation of agriculture to some extent,but there are still some deficiencies in the real-time irrigation control and the prediction of soil moisture content.Therefore,it is urgent to develop early warning service system with modern technology.The establishment of soil moisture forecast and warning service system can not only for the relevant government departments work in guiding farmers to provide technical support,but also for the establishment of agricultural informatization development in the future,the agricultural information intelligent operation management platform to provide guidance.Through consulting a large number of domestic and foreign literature,the traditional soil moisture forecast and early warning system of high cost,low efficiency,easy promotion and other issues,the use of sensor technology,database technology,computer network technology,computer programming technology,combined with the analysis of the current demand,design a set of soil moisture forecast and warning service system.The main work includes:This paper analyzes and compares the current situation of the research on the warning system at home and abroad.According to the current status of the development of the system,the demand analysis of the soil moisture system,demand analysis,the problems and disadvantages of doing analysis,and make analysis of the functional requirements of the system corresponding to the problem.The module comprises an acquisition module,management module and warning module.According to the demand analysis,combined with the objectives and principles of system design,the use of modular way in system development,the system architecture gives the overall framework design of the system.According to the soil moisture data acquisition module,data management and analysis module,pre alarm module moisture forecast etc.given the detailed design.Among them,the soil moisture forecast module adopts the BP neural network algorithm as the soil moisture forecast dynamic prediction model,and reference to other commonly used early warning mechanism for early warning of soil moisture with the system itself.Soil moisture early warning system is the use of JAVA programming,using the Jfinal framework,combined with Java Web and other computer network technology to achieve,and completed the establishment of the service site.The network realizes the data acquisition,data query and data management of soil moisture,soil moisture,soil moisture prediction function,alarm release.The system is powerful,easy to operate,easy to promote,reduce costs and improve work efficiency.The soil moisture forecast and early warning service system design and development work on the soil moisture forecast system development,which has important reference value and promote the role of agricultural informatization and automation of agricultural development and the development of wisdom,and it is our country agriculture moisture to informatization,network,intelligence development the only way which must be passed.
