Automatic control system for greenhouse in winter

Abstract

The invention relates to an automatic control system for a greenhouse in winter. The automatic control system comprises a three-rotating-shaft drum (1), a guiding roller (2), a wind preventing layer (3), an insulating layer (4), a wind reliving layer (5), a plastic film (6), a water collecting tank (7), a water storage pool (8), a nightside wall (9), an entrance (10) and two side walls (11). The working principles of the invention are as follows: the automatic control system for the greenhouse in winter is automatically opened according to needs of time and weather; when sunlight irradiates the greenhouse and meets demands of plants, the wind preventing layer (3) and the insulating layer (4) are intelligently put into operation so as to realize photosynthesis of the plants; when the temperature in the greenhouse is too high or the humidity is too great, the wind reliving layer (5) is put into operation; and when irrigation is needed, the water storage pool (8) provides a water source and enables irrigation to be realized. The wind preventing layer (3) can prevent the whole greenhouse from wind in night, and the insulating layer (4) exerts an insulating effect to guarantee the temperature in the greenhouse to meet needs of growth of the plants in winter.

Description

technical field [0001] The invention relates to a control system, in particular to a winter greenhouse control system. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's demand for crops continues to increase, and higher requirements are placed on the quality of crops. In winter, the temperature is very low, the weather is cold and there is a lot of snowfall, which seriously affects the growth of vegetables. In winter, there are many things to pay attention to in terms of heat preservation, antifreeze, lighting, and wind protection. There are many seasonal cold currents, which directly restrict most of the vegetables. High and stable yields of some cultivated crops in the region. The light time in winter is short, and increasing the light time will provide very good conditions for cultivated vegetables. The temperature inside the greenhouse will be very high at noon in winter, and the humidity will b...

AI Technical Summary

Problems solved by technology

The temperature inside the greenhouse will be very high at noon in winter, and the humidity will be very high due to watering and other reasons. It is necessary to frequently protect the greenhouse from wind, increase the exchange of air with the outside, and realize the function of cooling and dehumidification to prevent high temperature and high air humidity. And the fungal diseases are serious, it is difficult to meet the increasing requirements of people, and it is not conducive to the fierce market competition.

In addition, imperfect underground drainage systems or improper management and operation often cause crops to suffer from waterlogging stress, which seriously affects the quality, high yield and stable yield of crops, thus limiting the development of high-quality crops in greenhouses

[0003] At this stage, most of the methods of planting directly in the greenhouse and artificial wind protection are adopted. The ventilation and humidity removal in the afternoon is not realized, and the best production state of exposing the crops to the outside in sunny days is not only ineffective, but also has many negative effects.
