[0053] Among them, the controller controls the rotation of the second motor through a driving circuit. The driving circuit can adopt a common motor driving circuit in the prior art, and may include electronic components such as optocouplers, transistors, and MOS tubes. This application does not provide a detailed explanation.

[0054] Based on the above embodiments, the positions of sun rise and set are different in different seasons, so the present application sets a drive circuit, a second motor and a rotating table 11, which can control the photovoltaic steering to the positions of sun rise and set in different seasons to absorb more solar energy and increase the utilization efficiency of solar energy.

[0055] According to some embodiments, Figures 4 to 6 As shown, the light source detection device includes a photometric block 12, a first photoresistor 13, a second photoresistor 14, a third photoresistor 15, a fourth photoresistor 16, a fifth photoresistor 17, a third support rod 18 and a second support platform 19.

This is used to prevent the solar light source from irradiating two photoresistors at the same time, making it difficult for the controller to determine the specific position of the sun, thereby increasing the accuracy of light source detection. The fifth photoresistor 17 is arranged in the second groove 21 to accurately determine the position of the sun directly overhead, and further control the photovoltaic panel to receive solar energy directly overhead.

[0059] According to some embodiments, Figure 6 As shown, the tops of the four first grooves 20 are connected to light shielding plates 22 , and the four light shielding plates 22 shield a portion of the tops of the first photoresistor 13 , the second photoresistor 14 , the third photoresistor 15 and the fourth photoresistor 16 .

[0060] Based on the above embodiment, at noon when the sun is directly overhead, sunlight will irradiate the first photoresistor 13, the second photoresistor 14, the third photoresistor 15, the fourth photoresistor 16 and the fifth photoresistor 17. It is difficult for the controller to determine which photoresistor receives the strongest light intensity, so it is difficult to determine the specific position of the sun. Therefore, a sunshade 22 is added to cover a portion of the top of the first photoresistor 13, the second photoresistor 14, the third photoresistor 15 and the fourth photoresistor 16, so that the fifth photoresistor 17 receives the strongest light source, thereby more accurately determining the position of the sun.

The processor displays the light source direction information, light intensity information, rotation direction information of the rotating mechanism, voltage information and current information received by the second communication circuit through the display, so as to facilitate remote monitoring by the staff.

[0063] According to some embodiments, Figure 1 As shown, the monitoring system also includes a memory, which is connected to the processor.

[0064] Based on the above embodiment, the memory is used to store the light source direction information, light intensity information, rotation direction information of the rotating mechanism, voltage information, current information, etc. received by the processor through the second communication circuit.
