[0034] In one embodiment, if Figure 4 As shown, the present application discloses a method for controlling a sunshade device based on thermo-sensitive dimming glass, which specifically includes the following steps: S10: Acquire ambient lighting data, wherein the ambient lighting data includes light intensity and light irradiation angle, and generate an optimal light-facing angle according to the ambient lighting data; S20: Acquire real-time angle data of the solar panel, and generate a first adjustment strategy according to the optimal angle of facing the sun, wherein the first adjustment strategy is used to adjust the solar panel to better absorb solar energy and improve the conversion efficiency of the solar panel; S30: Acquire ambient temperature data and indoor temperature data, and generate a second adjustment strategy based on preset optimal indoor temperature data, wherein the second adjustment strategy includes the light transmittance of the thermo-sensitive dimming glass, and the open and closed states of the inner glass and the outer glass, and the second adjustment strategy is used to adjust the temperature adjustment efficiency of the shading device; Specifically, assume that the ambient temperature data is 30°C and the indoor temperature data is 25°C. According to the preset optimal indoor temperature data, in the embodiment of the present application, it is set to 22°C, thereby determining the second adjustment strategy. According to the temperature difference, it is judged that the indoor temperature is high and needs to be cooled. Based on this, the second adjustment strategy may include the following control measures: Transmittance adjustment of thermo-sensitive dimming glass: According to the high indoor temperature, thermo-sensitive dimming glass can adjust the transmittance so that less solar energy is received indoors, reducing the rate of increase of indoor temperature.

In other embodiments, the solar panel may not only receive sunlight as the only light source, but also other light sources, and light analysis is performed on multiple light sources in combination.
[0041] It should be noted that in actual applications, due to the presence of other buildings around the building, the light conditions outside the building are not uniform, that is, the light source information received by the surface of each solar panel is different. Some solar panels are blocked or reflected by surrounding buildings, resulting in different light source information from other solar panels. In this step, a specific analysis is performed based on the situation of each solar panel to improve the degree to which the solar panel receives solar energy, that is, to improve the overall effective utilization rate of the solar panel. Compared with the existing method of directly adjusting the solar panel based on the light conditions of the building's exterior wall, this solution adjusts each solar panel to improve the utilization rate of solar energy. The optimal light-facing angle is further described in the embodiments of the present application: S12: Based on the light source information and taking the center of the solar panel as the receiving center point, a real-time light irradiation angle of each solar panel is generated, wherein the straight line formed by the light source position and the receiving center point is the straight line L, the panel surface of the solar panel is the plane a, the angle formed by the straight line L and the plane a is α, and the light irradiation angle is α; S13: When plane a is perpendicular to straight line L, that is, the light irradiation angle α is 90°, it is regarded as the optimal light-facing state of the solar panel.

These data are input into the pre-set light source analysis model. The model can generate a light source portrait by analyzing the historical light source information, including the light source's changing trend, periodic changes and other characteristics.
[0043] By recording and analyzing historical light source information, the generated light source portrait can help better understand the characteristics and changing patterns of the light source, thereby providing a more accurate basis for subsequent light source prediction and adjustment.
[0044] S132: Acquire weather forecast information and input it into a preset light source prediction model, wherein the light source prediction model generates first predicted light source information corresponding to the weather forecast information based on the light source image; Specifically, weather forecast information for a period of time in the future, including sunlight intensity, cloud cover, etc., is obtained, and this information is input into the light source prediction model. Based on the light source portrait of historical light source information, the light source prediction model can generate first predicted light source information corresponding to the weather forecast information, that is, the light source conditions inferred according to the weather forecast. Combining weather forecast information and historical light source information, the generated first predicted light source information can help the system better predict future light source changes and provide a more reliable prediction basis for subsequent adjustment strategies. S133: the light source prediction model modifies the first predicted light source information according to the real time and based on the light source portrait to generate second predicted light source information; Specifically, as time goes by, the system updates the weather and lighting data in real time, and makes corrections based on historical light source information to generate second predicted light source information. If the weather forecast changes or the actual lighting deviates significantly from the prediction, the light source prediction model can correct the first predicted light source information based on real-time data to generate more accurate second predicted light source information. By correcting the light source prediction information in real time, it can more accurately predict future light source conditions, thereby improving the accuracy and practicality of light source prediction.

Record this temperature difference and record it with the timestamp. It should be noted that in the embodiment of the present application, the temperature difference is a vector value. If the temperature difference is a positive number, the ambient temperature is higher than the indoor temperature. If the temperature difference is a negative number, the ambient temperature is lower than the indoor temperature.
[0047] S32: calculating the indoor temperature change efficiency based on the indoor temperature data, and establishing a mapping relationship between the indoor temperature change efficiency and the temperature difference value based on a timestamp, so as to construct a temperature change-temperature difference data set; Specifically, by analyzing the indoor temperature data, the indoor temperature change efficiency is calculated, such as the rate at which the indoor temperature rises or falls within one hour. The system maps these data with the corresponding temperature difference values and constructs a temperature change-temperature difference data set. For example, at a temperature difference of 3 degrees Celsius, the rate at which the indoor temperature rises or falls is 0.5 degrees Celsius per hour. By constructing a temperature change-temperature difference data set, we can better understand the influence of temperature difference on the indoor temperature change efficiency and provide data support for subsequent temperature adjustment.

For example, when the temperature difference is 3 degrees Celsius, the first temperature factor is 0.7, which means that the indoor temperature change efficiency is 70% under this temperature difference.

For example, when the ambient temperature is 28 degrees Celsius and the indoor temperature is 25 degrees Celsius, according to the first temperature factor, the indoor temperature is predicted to rise to 26.5 degrees Celsius. By predicting the indoor temperature, the system can more accurately adjust the light transmittance of the thermo-dimming glass, the opening and closing states of the inner and outer glass according to the ambient temperature and the temperature difference, and improve the temperature regulation efficiency of the shading device, thereby improving indoor comfort and saving energy consumption.

For example, when the transmittance of thermo-sensitive dimming glass is 30%, the indoor temperature change efficiency is 0.6 degrees Celsius / hour; when the transmittance of thermo-sensitive dimming glass is 70%, the indoor temperature change efficiency is 0.3 degrees Celsius / hour. These data are recorded and a temperature change-transmittance data set is constructed.

For example, according to the analysis model, when the transmittance of the thermo-dimming glass is 30%, the transmittance factor is 0.8, indicating that the indoor temperature change efficiency is 80% at this transmittance; when the transmittance of the thermo-dimming glass is 70%, the transmittance factor is 0.5, indicating that the indoor temperature change efficiency is 50% at this transmittance. By generating the transmittance factor, the system can more accurately predict the indoor temperature change efficiency corresponding to different transmittances of thermo-dimming glass, providing a more accurate basis for subsequent temperature adjustment strategies.
[0052] It should be noted that in the embodiment of the present application, the machine learning algorithms of the temperature change analysis model are neural network algorithms and regression analysis algorithms.

For example, according to the transmittance factor, it is predicted that when the expected temperature change efficiency is 0.4 degrees Celsius / hour, the transmittance of the thermo-sensitive dimming glass needs to be set to 50%. By calculating the transmittance factor according to the expected temperature change efficiency and determining the transmittance of the thermo-sensitive dimming glass based on the transmittance factor, the system can automatically adjust the transmittance of the thermo-sensitive dimming glass according to the expected temperature change, further improving the accuracy and efficiency of indoor temperature regulation.
