Flow 1100 can be implemented by processing module 320 in tracker 120. Flow 1100 can be an exemplary implementation of step 1002 in process 1000.

Although in some embodiments, GPS positioning techniques (eg, GPS modules, GPS coordinates, or positioning data points) are used for illustration, it will be appreciated that other positioning techniques may be selected. For example, the longitude signal or the latitude signal of the tracker 120 can be acquired by the position signal. The position of the sun may include the elevation angle or square of the sun Position angle. The position of the sun can be obtained by a photosensitive sensor. The time signal can be obtained by a clock. In some embodiments, the clock can be time calibrated by a position signal to improve the accuracy of the clock.

The control signal may include a target tracking angle of the tracking bracket, a current signal, and the like. The current signal can be acquired by the detecting unit 430. At step 1302, the motor can be driven to operate. In some embodiments, the motor operation may be driven by drive unit 420 in tracker 120. At step 1303, it can be determined whether the motor is overloaded. In some embodiments, the overload condition of the motor can be determined by the current detected by the detection unit 430. For example, the detecting unit 430 can detect the current value when the driving motor is running, and output it to the control unit 410 in real time. When the motor is not overloaded, returning to step 1302, the motor can remain in an operating state. When the motor is overloaded, the process proceeds to step 1304 to cut off the motor power. For example, when the real-time current detected by the detecting unit 430 is greater than the threshold value, the control unit 410 outputs an instruction to cut off the power of the motor, and the driving unit 420 stops the motor operation. In some embodiments, the cut off power supply can further include a motor overload warning.

The software limit can limit the angle of the tracking bracket. The angle includes an azimuth and an elevation angle. In some embodiments, the azimuth angle may be plus or minus 180 degrees, and the elevation angle may be plus or minus 90 degrees. Further or alternatively, the operating range of the tracking bracket can be controlled by hardware limits. The hardware limit may be a limit switch. The limit switch can be installed outside the tracking range of the tracking bracket. When the tracking bracket does not exceed the tracking range, return to step 1302 and the motor can remain in operation. When the tracking bracket is out of the tracking range, at step 1306, the tracking range of the tracking bracket can be limited. In some embodiments, the limitation of the tracking range can be achieved by software limits. In some embodiments, when the system is abnormal and the tracking bracket is out of the operating range, the limit switch can have a limit protection effect on the tracking bracket.

It will be understood that those skilled in the art, after understanding the steps performed by the process 1300, may perform any combination of the steps and perform various modifications and changes to the steps of the process. However, these modifications and changes are still within the scope of the above description. For example, in some embodiments, step 1303 and step 1305 may be performed simultaneously, or step 1305 may not be performed, for example, the limit range of the tracking bracket may be directly limited by the limit switch. Variations such as these are within the scope of the present application.

14 is an exemplary flow diagram of the operation of a solar tracking system, in accordance with some embodiments of the present application. Process 1400 can be an exemplary implementation of a solar tracking system operation. After the tracker 120 is powered on, at step 1401, program parameter initialization can be performed. The program parameters may include an angle of the tracking bracket in the tracker 120. In some embodiments, the process of program parameter initialization may be to adjust the angle of the tracking bracket to an initial angle. At step 1402, system status and signal detection can be performed. The detection of the system status and signals may include clocks, storage, buttons, current, angle sensors, limit switches, encoders, wind speed signals, position signals, and the like. At step 1403, it can be determined whether the system has a fault. When there is a fault in the system, in step 1404, a fault alert can be made, returning to step 1402. When the system does not have a fault, at step 1405, the operating mode of the solar tracking system can be selected. The operational modes include an automatic mode, a manual mode, and/or a protection mode.

When the protection mode is selected, at step 1406, the tracking bracket can be leveled. In some embodiments, when the signal acquired by the system is bad weather or nighttime, the protection mode can be selected to level the tracking bracket. In some embodiments, after the tracking bracket is leveled, it may return to step 1402 to perform system status and signal detection in real time. For example, when the signal reacquired by the system is that the weather is fine during the day, the tracking bracket can repeat

steps

1403 and 1405 to perform the tracking operation.

When the automatic mode is selected, in step 1407, the target tracking angle of the tracking bracket can be calculated. The target tracking angle can be determined by an input signal. At step 1408, the tracking bracket can be driven to track the sun. The driving of the tracking bracket can be realized by the driving unit 420 by driving the motor. In some embodiments, when the tracking bracket tracks the sun, step 1102 can be returned to detect system status and signals in real time.

When the manual mode is selected, in step 1409, a button can be selected to control the direction of travel of the tracking bracket. The button may include an east button and a west button. When the east button is selected, the process proceeds to step 1410 where the tracking bracket is operated eastward. When the west button is selected, in step 1411, the tracking bracket is moved westward. In some embodiments, when the tracking bracket is operated to move eastward and westward by a button, it may return to step 1402 to perform system state and signal detection in real time. In some embodiments, the tracking bracket can be operated south or north. For example, a two-axis tracking bracket can achieve rotation of the bracket in the east-west direction and the north-south direction.
