s23, the control module judges whether the solar altitude is smaller than a second altitude threshold, judges whether the illumination intensity at the inner side of the rotating window is larger than the illumination threshold when the solar altitude is smaller than the second altitude threshold, and drives the rotating blades to reduce the turnover angle through the rotating blade driving unit when the illumination intensity at the inner side of the rotating window is larger than the illumination threshold until the illumination intensity at the inner side of the rotating window is smaller than or equal to the illumination threshold;
