Water And Fertilizer Integrated Service Cloud Platform Based On Internet Of Things Technology

With the development of science and technology,the irrigation and fertilization method of agricultural planting tends to be more and more automatic,standardized and integrated.The irrigation and fertilization of traditional agriculture have been unable to satisfy the needs of modern agriculture.Using Internet of Things technology to support the realization of water and fertilizer integrated is the trend of modern agricultural industry development.In order to solve the problems of automatic control of water and fertilizer integrated machine and regional environmental data acquisition of farmland.Combining the Internet of Things technology and the water and fertilizer integrated technology as the entry point,the Water and Fertilizer Integrated Service Cloud Platform based on the Internet of Things Technology is designed.The main research work is as follows:1)Design of water and fertilizer integrated machine.In this paper,a set of water and fertilizer integrated machine is designed by using the Internet of Things technology from the practical problems.It includes remote irrigation control technology,irrigation control system,electromagnetic valve control system and farmland irrigation pipe network system.In the system,the design and implementation of hardware selection are completed,and the automatic control and distribution of water and fertilizer supply between farmland are realized,thus in turn realizing the precise control and irrigation of water and fertilizer.2)Design of regional environmental data monitoring and collection equipment.Through the analysis of the farmland environment and combining the demand elements of the crops for the growing environment,the environmental monitoring and collection equipment is selected and designed in detail.Therefore,a set of regional environmental data monitoring and collection equipment is designed and implemented,and the environmental data between farmland is obtained and recorded in real time,which provided a basis for the fine operation of the water and fertilizer integrated machine and the platform.3)Data processing,analysis and prediction.In this paper,the prediction model of soil moisture content is used which based on multiple linear regression.Firstly,the farmland environmental sample data are processed.Secondly,the model is constructed according to the correlation degree between each impact factor and soil moisture content.Finally,the soil moisture content of the current farmland is analyzed and predicted.4)Design of water and fertilizer integrated service cloud platform.Combining the actual business needs and research contents of the farmland,the automatic control module,the manual control module,the farmland environmental data real-time monitoring and the equipment management module and other functional modules are designed.And combined with the design of the interface of water and fertilizer integration system,a set of Water and Fertilizer Integrated Service Cloud Platform based on the Internet of Things Technology is realized.This system is tested in the farmland environment.The results show that the whole water and fertilizer integrated service cloud platform runs stably.The water and fertilizer integrated machine is controlled accurately,the data is monitored and collected accurately,the data is wirelessly transmitted with high quality,and the automatic irrigation of water and fertilizer is realized accurately.
