At the same time, it is also difficult to solve the contradiction between the light and temperature required for vegetable growth. In addition, manual adjustment of greenhouse temperature is not only time-consuming and laborious, but also prone to errors.

[0030] Working principle: First, the temperature detector 6, humidity sensor 21 and light intensity sensor 22 monitor the temperature, humidity and light intensity data in the greenhouse in real time, and transmit them to the central controller 8 for analysis. The central controller 8 generates adjustment signals in real time according to the constant temperature, humidity and light requirements and sends them to the dynamic light and heat shielding component and the constant temperature adjustment component; Then, the dynamic light and heat shielding component and the constant temperature adjustment component cooperate with the dehumidification component to change the air temperature and humidity in the greenhouse in real time based on the light intensity and light direction; Finally, the multi-dimensional spectral optimization component performs spectral compensation adjustments on vegetables based on the type of vegetables being grown and their growth stage, improving photosynthesis efficiency, accelerating plant growth, and increasing yields.
