[0063] The surface of the regulating plate 1 is provided with a solar energy particle heat absorption coating, which is black and covered with evenly distributed coating particle sand to improve the heat absorption efficiency.

[0064] The controller uses an adaptive control algorithm model to adaptively control the temperature and humidity in the greenhouse to maintain stability;

[0065] The adaptive control algorithm model is:

[0066]

[0067] Where, is the square sum of the deviations of each environmental parameter from its ideal value, T dev , H dev , S dev They are the deviations between the actual values ​​of temperature, humidity, and light intensity and their ideal values, -α is the deviation penalty coefficient, which can range from -1 to -0.1, β is the reward value, which can range from 50 to 500, and -γ is the fixed deviation penalty value, which can range from -1000 to -100. In practical applications, the specific values ​​of α, β, and γ should be adjusted according to the actual greenhouse environment, plant species, seasonal changes, and other factors to achieve the best control effect. In practical applications, the initial value can be selected from the above recommended range, and then the system performance and crop growth can be observed, and the adjustment can be gradually optimized to achieve the best temperature and humidity control effect.

[0068] The ideal range of temperature is 20°C to 28°C, the ideal range of humidity is 60% to 80%, and the ideal range of light intensity is 3000 to 5000 lux;

[0069] The light transmission adjustment range and air transmission adjustment range of the adjustment device 100 are both 10-100%, which means closing the light transmission to fully opening, and the actual adjustment is performed according to system analysis.

[0070] This system integrates temperature and humidity sensors and light sensors to monitor the environmental parameters in the greenhouse, and automatically adjusts the water vapor circulation and controls the humidity through algorithm analysis.

[0071] The thermal insulation water storage device is a thermal insulation water storage device arranged underground. Since the deep underground layer has a relatively constant thermal insulation response to light and temperature difference, the soil temperature deep underground is relatively stable and is less affected by ground temperature fluctuations. Therefore, it can be used as a natural temperature buffer zone, which can greatly reduce the impact of light and temperature difference. In addition, since the underground environment isolates the direct influence of light, the thermal insulation water storage unit can avoid excessive evaporation of water and excessive temperature caused by direct sunlight, making water management and temperature regulation more efficient. The controller automatically performs single or multiple thermal insulation water storage units 9 in combination and circulation according to the data of the first water thermometer, the second water thermometer and the temperature sensor after analysis.

[0072] This system uses an adaptive control algorithm model that can dynamically analyze environmental parameters and automatically adjust control strategies to ensure that the greenhouse environment is always close to ideal conditions. This not only improves the accuracy of regulation, but also reduces manual intervention and improves the automation and intelligence level of the system.

[0073] Working principle: The temperature and humidity control system of the present invention is provided with an adjusting device 100, which includes a plurality of adjusting plates 1 arranged at intervals, each adjusting plate 1 can rotate to change the light transmittance between two adjacent adjusting plates 1, and the temperature in the greenhouse can be adjusted by adjusting the degree of direct sunlight; at the same time, in conjunction with the water circulation system, circulating water of different temperatures is introduced into the adjusting plate 1, and multi-stage heating and cooling are performed in coordination; and the flexible light-transmitting plate 2 can also slide by rotating the adjusting plate 1, so that the air-permeable part is exposed to achieve ventilation, and the humidity in the greenhouse can be adjusted in coordination with the spraying device;

[0074] In the above, the temperature and humidity in the greenhouse are coordinated by adjusting the degree of direct sunlight, water circulation, air permeability and water spraying amount.

[0075] The regulating device 100 can use the regulating plate 1 to absorb the heat energy generated by sunlight during the day, and store the absorbed heat water in the corresponding thermal insulation water storage unit 9 in sequence after reaching the corresponding temperature through dynamic water circulation; at night, the hot water stored during the day is used to maintain the temperature in the greenhouse through heat exchange by combining it with water of different temperatures; at the same time, due to the heat exchange, some of the thermal insulation water storage units 9 store ice water that has been cooled to the corresponding temperature. In this way, the ice water that has undergone heat exchange can be used to continue to maintain the temperature in the greenhouse during the day. This reciprocating cycle can achieve temperature and humidity stability for greenhouses in areas with sudden temperature differences and sufficient light intensity.

[0076] In summary, the temperature and humidity control system of the present invention solves the problem of temperature and humidity control in greenhouses in high-altitude areas with large temperature differences between day and night and strong light intensity. The core is the adjustment device 100, which consists of a rotatable adjustment plate 1 installed on the top of the greenhouse. A flexible light-transmitting adjustment plate 1 is arranged between the plates, which can not only adjust the light transmittance to affect the temperature, but also maintain the temperature in the greenhouse through its internal water circulation, and can also adjust the humidity through the air permeable part, so as to achieve comprehensive control of light, temperature and humidity, and make real-time adjustments according to environmental parameters to ensure that the most suitable conditions are maintained in the greenhouse. Optimize resource utilization and provide efficient and intelligent environmental control solutions for modern agriculture.

The control system for adjusting temperature and humidity in a greenhouse as claimed in claim 8, characterized in that: The ideal range of temperature is 20°C to 28°C, the ideal range of humidity is 60% to 80%, and the ideal range of light intensity is 3000 to 5000 lux; The light transmittance adjustment range and air permeability adjustment range of the adjustment device are both 0-100%.

10. The control system for adjusting temperature and humidity in a greenhouse as claimed in claim 1, characterized in that: The heat-insulating water storage device is a heat-insulating water storage device arranged underground. The controller automatically performs a single circulation or a combined circulation of multiple heat-insulating water storage units based on analysis of data from the first water thermometer, the second water thermometer and the temperature sensor.
