Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, the greenhouse automatic control system of the present invention includes a motor 1 connected with a film rolling device, which can roll up the greenhouse film 11 or put down the greenhouse film 11, thereby allowing the greenhouse to communicate with the outside world. It also includes an electronic control unit ECU2, the ECU2 is preferably formed integrally with the motor 1, or the ECU2 is arranged on the motor 1. The motor 1 is preferably a stepper motor.

[0013] It also includes two sets of sensor devices respectively arranged inside and outside the greenhouse, and each set of sensor devices includes a temperature sensor 4, a humidity sensor 5, an illumination sensor 6, and the like. Of course other types of sensors may also be included.

[0014] When the temperature in the greenhouse is too high, the ECU2 contro...

Abstract

The invention provides a greenhouse automatic control system comprising a greenhouse film and a motor. The motor is connected with a film rolling device which can roll up or down the greenhouse film. The system further comprises an electronic control unit ECU which is formed integrally. The system further comprises a temperature sensor and a light sensor which are arranged inside a greenhouse. When the ECU receives signals from the sensors indicating that the temperature is too high or the light is insufficient, the ECU makes the motor rotate, a greenhouse reel is thus driven to rotate, and the greenhouse film is opened. When the ECU receives signals from the sensors indicating that the temperature is too low or the light is too strong, the ECU makes the motor rotate, the greenhouse reel is thus driven to rotate, and the greenhouse film is closed. The greenhouse automatic control system has a high degree of automation, and can monitor the state parameters of a greenhouse and intelligently control the greenhouse.

Description

technical field [0001] The invention relates to a control system, in particular to an automatic control system for a greenhouse. Background technique [0002] Film greenhouse is a kind of greenhouse widely used in our country. The film greenhouse is characterized by the use of plastic film as a sunshade and heat preservation shed. In winter, it can provide a greenhouse growth period and increase production, and is mostly used for plant cultivation or seedling cultivation of vegetables, flowers, forest trees, etc. [0003] In summer and autumn, due to the high temperature and strong light, it is necessary to control the temperature, humidity and light of the greenhouse and roll up the greenhouse. In case of sudden rain, strong wind, etc., put down the greenhouse again. [0004] However, the control means in the prior art is usually manual or electric, and the film is rolled up by adding a film roll, so as to increase the ventilation of the greenhouse and reduce the tempera...
