In order to improve the level of automation and scientific management of greenhouse planting and reduce the output of labor force, greenhouse cucumber production as an example is studied, a kind of intelligent control system of cucumber production in the Internet of things is designed. On the basis of many factors such as weather, time, humidity, temperature and so on, in combination with the specific needs of daily production of cucumber, the greenhouse shutter control model, recovering stage model, early-flowering stage and result stage model is designed by using wireless communication technology, information collection technology, information processing technology and other intelligent technologies. It has realized the precision automatic control of the greenhouse. At the same time, in order to facilitate the user to see the growth of cucumber and the information of the greenhouse environment in real time, the mobile phone APP remote control, monitoring and warning services are provided. Experiments show that the system is stable in data transmission and reliable in environmental regulation, which meets the needs of intelligent control in a modern greenhouse environment, and significantly improves the efficiency of cucumber production.
