Example Embodiment

[0040] Example 1

[0041] like figure 1 As shown, a schematic block diagram of a solar azimuth tracking controller, the controller includes:

[0042] The microprocessor is used to receive and process the data of the GPS module, the photosensitive probe, the motor drive module and the communication circuit, and is also used to calculate the position of the sun and drive the tracking controller to adjust the angle of the solar module;

[0043] a power supply circuit for providing the power supply voltage required by each part of the controller through the microprocessor;

[0044] GPS module, used to provide the latitude, longitude and time information of the location of the controller;

[0045] Photosensitive probe, used to provide the sun light angle signal to the microprocessor;

[0046] The motor control module is used to drive and monitor the motor;

[0047] The manual control circuit is used to realize the function of manual control of the motor;

[0048] The communica...

Example Embodiment

[0063] Example 2

[0064] This embodiment is an optimization of Embodiment 1.

[0065] When the sun azimuth tracking controller appears to be covered with snow, leaves or other debris, the system needs to perform the snow-reversing action. image 3 As shown, the microprocessor calculates the sun angle through the microprocessor according to the received time information, and judges whether the motor control module performs the automatic snow-reversing action function. Go to step (3), if it is not necessary to perform the automatic snow-reversing action, go to step (6). Other specific implementations are the same as in Example 1.

Description

technical field [0001] The invention relates to a solar energy automatic tracking power supply system, in particular to a solar azimuth tracking controller and a tracking method thereof. Background technique [0002] The tracking methods of existing solar automatic tracking controllers can be divided into two types: photoelectric tracking method and timing tracking method. [0003] The photoelectric tracking method is to drive the tracking mechanism to passively track the position of the sun after judging the change of the sunlight irradiation angle by the photosensitive sensor. Its advantage lies in its high tracking accuracy, but its anti-interference ability is poor, it is easily affected by scattered light, there are many misoperations, and it consumes a lot of energy. [0004] The principle of the timing tracking method is to use the law of the earth's rotation of 15° per hour, and use the real clock to adjust the angle of the solar cell module at intervals to track th...
