When the pressure values are different and have different magnitudes, and the pressure values are different greatly, the fact that the sun is in the morning or afternoon time period at this time is indicated, and the projection position needs to be further located at this time.
In this embodiment, when the pressure values are not equal, controlling the on-off of the first electromagnetic valve 91 and the second electromagnetic valve 92 to adjust the inclination angle of the photovoltaic module 6 includes:
When the pressure values are not equal, identifying the minimum pressure value of the plurality of pressure values, and positioning the angle of the photosensitive unit where the minimum pressure value is located in the circumferential direction of the base 702, wherein the angle is an illumination rotation angle, for example, 360 degrees are total in the circumferential direction of the base 702, 8 rows of photosensitive units are shared in fig. 9, the included angle between two adjacent rows is 45 degrees, the position where the photosensitive unit on the right side is located is defined as the initial 0 degree, and the included angle is calculated from the counterclockwise direction, and then the included angles of other photosensitive units are sequentially determined to be 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, 315 degrees and 360 degrees (namely, the initial 0 degree) according to the counterclockwise sequence; the pressure value of a certain pressure sensor 707 is minimal, which means that the temperature in the isolation chamber 706 is low, that is, the isolation chamber 706 is shielded by the projection, so as to determine at least the position of the photosensitive element where the isolation chamber 706 is located.
Judging whether the difference between the pressure values of two adjacent pressure sensors 707 in the photosensitive unit where the minimum pressure value is located is greater than a first threshold value; because the projection may obscure a portion of an isolated chamber 706, the pressure value of the isolated chamber 706 is between a minimum and a maximum value.
When the difference between the pressure values of the adjacent two pressure sensors 707 is greater than the first threshold value, positioning the position information of the pressure sensor 707 corresponding to the smaller pressure value; when the shadow masks most of a certain isolation cavity 706, the temperature in the isolation cavity 706 is greatly different from the temperature in the isolation cavity 706 completely exposed to the sun, which is reflected in the pressure value, that is, the pressure value of the two is greatly different, and when the pressure value of two adjacent pressure sensors 707 is greatly different from the first threshold value, it is indicated that the shadow masks most of the isolation cavity 706 with smaller pressure value, and at this time, it can be approximately considered that the projection completely masks the isolation cavity 706, so that the error of predicting the sun illumination angle is reduced.
