[0055] The photovoltaic power system structure of the present application is described below with reference to the accompanying drawings.

[0056] like Figure 1 As shown, the photovoltaic power supply system structure includes three photovoltaic indication stations, which are distributed in various places in a designated area. The designated area can be an urban area, a township or other area. The photovoltaic indication station can be a tower-type building. The relationship between the three photovoltaic indication stations can be that the three mapping points on the horizontal plane form three vertices of an equilateral triangle. Each photovoltaic indication station has positioning information, and the positioning information of each photovoltaic indication station is pre-calibrated. A collection module is provided on the top of the photovoltaic indication station. The collection module includes an illumination sensor and a distance sensor. The illumination sensor is used to collect light intensity, and the distance sensor is used to detect the distance between the collection module and a preset position on the photovoltaic indication station as its own height value. For example, the preset position can be set as the top of the photovoltaic indication station, and the distance sensor is used to detect the distance between the collection module and the top of the photovoltaic indication station.

[0057] The above-mentioned acquisition module is also associated with the photovoltaic indication station where it is located, that is, associated with the positioning information of the photovoltaic indication station where it is located.

[0058] The photovoltaic power system structure also includes a photovoltaic module, which includes a photovoltaic power generation panel, a battery pack, a regulating unit, a positioning module and a controller;

[0059] Among them, the photovoltaic panels are used to convert light energy into electrical energy, and the battery pack is used to store electrical energy. The photovoltaic panels and the battery pack are connected through an AC / DC module. The photovoltaic panels convert light energy into electrical energy, and then the AC / DC module converts the alternating current into direct current and stores it in the battery pack; the positioning module is used to obtain the current position information of the photovoltaic module, and the positioning module can use a GPS positioning unit to achieve the acquisition of position information.

[0060] The controller is used to receive the light intensity sent by the acquisition modules on the three photovoltaic indicator stations, the positioning information of the associated photovoltaic indicator stations, and the height value of its own location, and analyze the input model in combination with the current position information to infer the angle value;

[0061] Specifically, the model is trained in the following way:

[0062] Each information sample in the information sample training set is labeled to mark the angle value of each information sample, each information sample includes the light intensity of the collection modules on the three photovoltaic indication stations, the positioning information of the photovoltaic indication stations associated with the collection modules on the three photovoltaic indication stations, the height value of the collection modules themselves on the three photovoltaic indication stations, and the location information of the photovoltaic module; the angle value is associated with all or part of the information in the information sample; and the neural network is trained through the labeled information sample training set to obtain a model.

[0063] Among them, the information samples are obtained by conducting a large number of experiments in the designated area. For example, multiple experiments are conducted in the designated area, and each experiment places the photovoltaic module at a different position in the designated area, so as to have different current position information of the photovoltaic module, and then obtain the light intensity collected by the collection modules on the three photovoltaic indication stations, and receive the positioning information of the photovoltaic indication stations associated with the collection modules on the three photovoltaic indication stations, as well as the height values ​​of the collection modules themselves on the three photovoltaic indication stations, so that multiple groups of information samples can be collected, and then the corresponding angle values ​​are labeled for these information samples, and then the neural network is trained through the labeled information samples to obtain the model.

[0064] After obtaining the angle value through analysis and reasoning of the model, the controller sends the angle value to the adjustment unit, and the adjustment unit adjusts the angle of the photovoltaic panel according to the angle value.

[0065] Specifically, the adjustment unit includes an analytical subunit, an X-axis motor, a Y-axis motor and a Z-axis motor, wherein the analytical subunit is used to analyze the angle value into an angle on the X-axis, an angle on the Y-axis, and an angle on the Z-axis; the analytical method can be directly decomposed into three angle components by vector decomposition. The X-axis motor is used to adjust the angle of the photovoltaic panel on the X-axis, the Y-axis motor is used to adjust the angle of the photovoltaic panel on the Y-axis, and the Z-axis motor is used to adjust the angle of the photovoltaic panel on the Z-axis. The installation method between the three motors can be achieved by stacking them in sequence, that is, the Y-axis motor is fixedly installed on the output shaft of the Z-axis motor, the X-axis motor is fixedly installed on the output shaft of the Y-axis motor, and then the photovoltaic panel is fixedly installed on the output shaft of the X-axis motor. The three motors can be rotated to achieve the adjustment of the angle of the photovoltaic panel.

[0066] In one embodiment, a height adjustment device for adjusting the height of the collection module is provided on the top of the photovoltaic indication station. The height adjustment device can be adjusted in the form of an electric cylinder, that is, the cylinder body of the electric cylinder is fixedly installed on the top of the photovoltaic indication station, and then the collection module is installed on the end of the piston rod of the electric cylinder, so that the collection module can be driven to rise and fall and adjust the height. The above-mentioned collection module also includes a height generation unit, refer to Figure 2 , the height generation unit is used to perform the following steps:

[0067] S10, obtaining a current timestamp every preset time;

[0068] S12, generating a hash value according to the current timestamp and the positioning information of the associated photovoltaic indicator station;

[0069] S14, generating a height adjustment value according to the hash value;

[0070] S16, sending the height adjustment value to the height adjustment device, and the height adjustment device adjusts the height of the acquisition module according to the height adjustment value.

[0071] The preset time is a preset value, for example, 5 minutes, and the height generation unit obtains the current timestamp every 5 minutes; then a hash value is generated according to the current timestamp and the location information of the associated photovoltaic indicator station using a hash algorithm, and then a height adjustment value is generated according to the hash value; refer to Figure 3 Specifically, generating a height adjustment value according to the hash value includes:

[0072] S141, calculating the ratio of the sum of the first n digits of the hash value to 9n;

[0073] S142: multiply the ratio by a preset value to obtain a height adjustment value.

[0074] Among them, n is a preset positive integer, and the preset value can correspond to the standard stroke of the electric cylinder. For example, if it is set to 7, the sum of the first 7 digits of the hash value is taken, and then the ratio with 63 is calculated, and then the ratio is multiplied by the preset value, such as 800mm, to obtain the height adjustment value. After obtaining the height adjustment value, the electric cylinder adjusts the acquisition module to the corresponding stroke position according to the height adjustment value.

[0075] The present application also provides a method for adjusting the angle of a photovoltaic panel, based on the above photovoltaic power system structure, referring to Figure 4 ,include:

[0077] S2. Send the angle value to the adjustment unit, and the adjustment unit adjusts the angle of the photovoltaic panel according to the angle value.
