Abstract
This paper designs an intelligent control system of agricultural greenhouses that suits the situation of our country and is simple in operation, practical and cost-effective. The intelligent control system of agricultural greenhouse based on STC89C52 is designed. The system is mainly composed of data acquisition unit, control unit and regulation equipment. Data acquisition unit mainly includes carbon dioxide concentration, temperature and humidity, light intensity, soil moisture and other sensors; The control unit takes microcontroller STC89C52 as the core, including power module, alarm module and control output module, etc. The control equipment mainly includes lights, LED displays, water pumps and fans. The environmental parameters of the greenhouse collected by the sensor are transmitted to the single chip microcomputer through the communication module. After processing the data, according to the principle of intelligent control, the corresponding control signal is output to control and regulate the environment of the greenhouse. Finally, the interference design of the system, so that the system can run stably. This has a very large application value in agricultural greenhouse planting, it has a very important significance to our agricultural production.
