Measurement And Control System And Information Management System Of Smart Agricultural Greenhouse

With the rapid development of economy and modern technology,modern agriculture has begun to develop towards intellectualization.The use of various agricultural facilities has created a good environment for the growth of crops,among which greenhouse has become an important project for agricultural cultivation.At present,the automation degree of traditional agricultural greenhouse is low,and the collection technology of environmental data is relatively backward.Therefore,it is very necessary to develop a complete set of Smart agricultural greenhouse measurement and control and information management system.The system can accurately control the parameters of agricultural greenhouse,make agricultural planting more Smart and scientific.On the basis of saving manpower,it can also improve the quality and yield of crop planting in greenhouse.Smart agricultural greenhouses are the development direction of greenhouse greenhouse cultivation.To promote the large-scale development of agricultural greenhouse planting.Firstly,the research status and development trend of greenhouse agriculture at home and abroad are analyzed,and deeply understands the demand of modern agricultural greenhouse.In order to improve this situation,a set of Smart Agriculture Greenhouse Measurement and Control and Information Management System is designed and developed,which can save a lot of manpower and physical strength,improve the quality and yield of crop cultivation in greenhouse,and changing the backward appearance of traditional agricultural greenhouses.Secondly,the overall structure of the system and the technology used in the system are introduced,including modern measurement and control technology,wireless communication technology,sensor technology.The system is mainly composed of sensors,measurement and control module,communication module,control module,database,server and Smart agricultural greenhouse information management system.The sensor communicates withmicrocontroller with 485 interface,collects data by Modbus protocol,then uploads it to server,saves it to database,and provide a data foundation for information management systems.Thirdly,the overall scheme of the measurement and control system is designed.The system takes STM32F103RET6 as the core to design the required circuit,which mainly includes the design and implementation of MCU control circuit,RS-485 interface circuit,WiFi module circuit and control module.The related hardware design circuit diagram,software flow chart and part of the program code are given.Finally,the design and implementation of the Smart agricultural greenhouse information management system are introduced in detail.The information management system uses B/S architecture,and develops system interface based on SSM framework to meet user needs,which is conducive to the management and use of agricultural greenhouses.
