Design And Implementation Of Greenhouse Digital Management System Based On The Internet Of Things

With the rapid development of computer technology,Internet of Things technology,sensor technology and mobile Internet technology,digital greenhouse is becoming an important form of facility agriculture.In this paper,the Internet of things as the core,integrated sensor technology,embedded microprocessor technology,computer network technology,mobile Internet technology and other techniques,designed and implemented to kind of information intelligent context-aware intelligent plant growth,growth conditions of the regulation device Control,greenhouse management of the three-tier structure of the greenhouse management system.The main work of the paper is as follows:(1)The actual demand of the greenhouse was analyzed,and the six functional modules of the plant growth environment parameters,intelligent perception,plant growth condition adjustment equipment intelligent monitoring,data transmission,data storage,video monitoring and user management were determined and designed.By the intelligent perception layer,intelligent control layer and management information layer composed of three-tier system architecture.(2)Designed based on CC2530 greenhouse green sensor,through the greenhouse environment of the multi-point layout,to achieve the air temperature/humidity,soil temperature/humidity,soil pH,light intensity,CO2 concentration and video surveillance real-time acquisition,Using ZigBee wireless network communication and intelligent controller interoperability.(3)The STM32-based greenhouse greenhouse intelligent controller is designed,and the selection and setting of three control modes are realized by sensor linkage,timing,near/remote manual,and the greenhouse,And other equipment monitoring,the use of WiFi communications and cloud storage server interoperability.And the hardware composition diagram and software design block diagram was given.(4)The remote monitoring and management information system was developed.Based on the B / S architecture of the greenhouse management information subsystem of the greenhouse,based on the iOS operating system of the greenhouse mobile phone APP mobile Internet control platform to achieve the greenhouse remote monitoring,remote control of the greenhouse greenhouse,Video surveillance,and plant and personnel management.The design of the system successfully applied in Hainan Broadland Orchid Technology Co.,Ltd.Orchid Greenhouse.The results of the actual operation show that the system can collect and store the greenhouse environmental growth parameters,and can correctly monitor the plant growth condition adjustment equipment,through the mobile phone APP remote control of the greenhouse management,the system is stable,the operation is easy to use,to meet the digital greenhouse design requirements.
