[0043] S302: The direction of sunlight is acquired, and the setting angle of the photovoltaic panel is determined according to the direction of sunlight;

[0044] S304: The displacement parameter of the support rotating device is determined according to the setting angle of the photovoltaic panel;

[0045] S306: The operation of the support rotating device is controlled according to the displacement parameter.

[0046] In the above-mentioned embodiments, a photovoltaic rotating device which can rotate following the sunlight is provided, comprising a photovoltaic plane support for supporting a photovoltaic panel and a support rotating device for rotating the photovoltaic plane support according to the direction of sunlight so that the photovoltaic panel is vertically arranged with the sunlight.

After the north-south direction angle is determined based on the longitude and latitude, only the east-west direction angle needs to be adjusted in the use process of each day, so that the utilization rate of sunlight can be optimized.

[0048] Further, the direction of the sunlight is obtained, including: obtaining the longitude and latitude of the region where the photovoltaic panel is located; determining the moving speed of the sunlight according to the longitude and latitude, setting the adjustment frequency of the photovoltaic rotating device according to the moving speed, and obtaining the direction of the sunlight according to the adjustment frequency.

[0049] In a preferred embodiment of the present application, the displacement parameter of the support rotating device is determined according to the setting angle of the photovoltaic panel, including: calculating the distance between the second connecting point of the first rotating rod 3 and the top of the sliding rod shaft 2 and the distance between the second connecting point of the second rotating rod 4 and the top of the sliding rod shaft 2 according to the setting angle of the photovoltaic panel; calculating the sliding distance of the second connecting point of the first rotating rod 3 according to the distance between the second connecting point of the first rotating rod 3 and the top of the sliding rod shaft 2 and the total height of the sliding rod shaft 2, and calculating the sliding distance of the second connecting point of the second rotating rod 4 according to the distance between the second connecting point of the second rotating rod 4 and the top of the sliding rod shaft 2 and the total height of the sliding rod shaft 2; wherein the initial position of the second connecting point of the first rotating rod 3 is the lowermost part of the first sliding groove 6, and the initial position of the second connecting point of the second rotating rod 4 is the lowermost part of the second sliding groove 7. That is, the first rotating rod 3 and the second rotating rod 4 move from bottom to top, and the moving distance of the first rotating rod 3 can be obtained by calculating the distance between the second connecting point of the first rotating rod 3 and the top of the sliding rod shaft 2, and the total height of the sliding rod shaft 2 minus the distance between the second connecting point of the first rotating rod 3 and the top of the sliding rod shaft 2. Similarly, the moving distance of the second rotating rod 4 can be obtained by calculating the distance between the second connecting point of the second rotating rod 4 and the top of the sliding rod shaft 2, and the total height of the sliding rod shaft 2 minus the distance between the second connecting point of the second rotating rod 4 and the top of the sliding rod shaft 2. Through the above steps, the moving distance of the rotating rod is accurately calculated, the angle of the photovoltaic panel is accurately adjusted, and the perpendicular setting of the photovoltaic panel and the sunlight is realized.
