Design of a greenhouse remote measurement and control system based on internet of things technology

Abstract

This study designed a greenhouse remote measurement and control system based on Internet of Things technology. The system is based on WebOP Designer configuration software and Modbus communication protocol, with Adam4060 relay output module and intermediate relay as the control core. Remote monitoring of the greenhouse environment is achieved through cooperation with the greenhouse environmental data acquisition sensor, the Adam-4117 analog input module, the industrial-grade programmable human-machine interface, the internet/intranet and the Web Access web database. Local customers can view real-time data and historical curves by operating the human-machine interface, and control the operation of each actuator in the greenhouse according to the alarm status and warning line settings. The remote client can log in to the webpage database through the PC client and the mobile client conveniently and quickly. The system is beneficial to reduce labor costs and improve the informationization level and management efficiency of agricultural production. Through the access of expert systems, precise control of crop growth environment is achieved, and the economic benefits of crops are improved.
