Vegetable greenhouse ventilation system

Abstract

The invention discloses a vegetable greenhouse ventilation system which comprises a ventilation device, a controller and a temperature-humidity collector. The ventilation device comprises a door frame, a ventilation door, a rotating shaft and a steering engine, the rotating shaft is fixedly mounted in the middle of the ventilation door and movably mounted on the door frame, a big gear is arranged at the top of the rotating shaft, a small gear is mounted on the steering engine, the small gear and the big gear are meshed together, the steering engine is electrically connected with the controller, the temperature-humidity collector is used for collecting temperature and humidity in a vegetable greenhouse and sending the same to the controller in a wireless mode, and the controller controls the steering engine to rotate according to the temperature and the humidity in the vegetable greenhouse so as to control the ventilation door to achieve the objective of controlling ventilation. The vegetable greenhouse ventilation system is convenient to use, good in ventilation control effect, needless of manual control and automatically adjustable in temperature and humidity in the vegetable greenhouse, and a wireless communication mode is adopted, so that temperature-humidity collecting points can be arranged flexibly.

Description

technical field [0001] The invention relates to the technical field of vegetable greenhouse ventilation, in particular to a vegetable greenhouse ventilation system. Background technique [0002] When using a greenhouse to grow vegetables, special attention should be paid to the temperature and humidity of the environment in which the vegetables grow. If the temperature and humidity in the greenhouse are not suitable, it will cause poor growth of the vegetables. When there is sufficient sunlight during the day, the temperature in the greenhouse will rise. Ventilation and cooling not only seriously affect the growth of vegetables, but even lead to the infestation and occurrence of vegetable pests and diseases. However, the current ventilation devices for vegetable greenhouses cannot achieve the function of automatic ventilation, and manual inspection and ventilation are required, which is time-consuming and laborious to use. There is a large error in the inspection. Contents...
