In addition, when the light intensity is insufficient and the image on the photoelectric detector is blurred and photoelectric tracking is difficult, the clock is matched with the controller to perform time control tracking so as to approximately track the sun. The clock sub-circuit is required to continue to operate after the tracking system is powered off, and the clock can keep synchronous with the current time after the tracking system is powered on again. In addition, the clock needs programmable function to satisfy the requirement of time synchronization operation of the clock in a long distance. Therefore, the clock chip, the high-precision crystal oscillator and the battery are adopted in the design to form a clock circuit, and the clock is continuously operated by supplying power to the system through the battery after the system is powered off.

In fact, most areas in China are in northern hemispheres [8-11], the solar panel 8 is only rotated 180 degrees in the horizontal direction from east to south to west in practice, the rotation range is 0-60 degrees in the vertical direction due to process limitation, and rotation and data cyclic acquisition are carried out according to the latter step method. And circularly collecting the output data of the solar panel 8 from the position of each angle coordinate from morning to evening, thus obtaining the data of the solar energy corresponding to each angle coordinate along with the time change, averaging the data and drawing a trend curve, wherein the angle coordinate corresponding to the maximum average power is the required optimal angle, the optimal installation angle of the solar panel 8 in the day/quarter/year can be obtained according to the thought, and the working angle of the solar panel 8 is controlled through the working process.

Firstly, in order to reduce energy consumption, a clock module is required to set the time for starting tracking every day, a clock sub-circuit controls an illumination intensity sensor to periodically detect the illumination intensity of sunlight in the environment, and whether the environment is daytime, rainy days or nighttime is judged. And if the day or the rainy days are judged, starting tracking. When the interference of real night instead of the shelters is identified, the automatic reset can be realized.

In order to reduce energy consumption, the computer designs and appoints the time for starting tracking according to the change rule of sunrise time, and the tracking program is started after the time data collected by the clock module judges that the appointed time is reached, and the current illumination intensity of the surface of the battery plate is collected. Since the sun takes 24 hours to wind around the earth, and rotates 1 in every 4 minutes on average, in order to reduce repeated adjustment of the tiny angles of the solar panel and reduce energy consumption, the controller reads the data of the illumination intensity sensor every 4 minutes, judges day, rainy day or night, and enters the next step until the judgment is that the solar panel is not at night. And when the wind speed is judged to be not at night, namely the wind speed signal is collected in the daytime or in rainy days, the wind speed sensor collects the signal every 4 minutes, when the wind speed is greater than the set value, the tracking program is interrupted, the next time of collecting the wind speed signal is waited until the wind speed is reduced to be lower than the set value, and the tracking is resumed. Then detecting the illumination intensity, selecting a tracking mode according to the illumination intensity to track for the first time: and starting photoelectric detection tracking in sunny days, driving the stepping motor to drive the photoelectric detector and the solar panel 8 to move, starting searching and tracking the position of the sun, enabling the solar panel to be aligned with the sun, suspending tracking after the completion, stopping the stepping motor, and enabling the system to enter a waiting state until a signal of the illumination intensity sensor is received next time. And starting time control tracking in rainy days to enable the battery panel to rotate 1 in the horizontal direction and the vertical direction respectively, and then entering a standby state. When the rainy day changes to sunny day, photoelectric tracking is adopted. If the judgment result is that the solar panel is at night, no action is taken, the solar panel directly enters a waiting state, when the judgment result is that the solar panel is at night twice, resetting operation is carried out, continuous pulse signals are output to enable the solar panel 8 to rotate downwards and eastward, the motor power supply is cut off through the stop switch and feedback, then the tracking control circuit is cut off, and the clock sub-circuit power supply is reserved.

The whole control system is divided into four parts of maximum power point tracking, automatic lifting control, automatic rotation control and voltage conversion. The control system is composed of a control program and a circuit. The solar cell control system is connected with an external remote control, a program is triggered to run through a button on the external remote control, a preset effect is achieved, the solar altitude angle changes constantly along with time, energy which can be generated when the solar cell is irradiated on the solar cell by different solar altitude angles is also different, therefore, a maximum power point tracking system (MPPT) is added in the control system, the solar irradiation angle is adjusted constantly, and the maximum output power of the solar cell is guaranteed. The maximum power point tracking system is characterized in that a controller sends a rotation command to a motor, the motor rotates, meanwhile, an electric power data module returns a measured power signal at each moment to the controller, when the maximum output power position is reached, a program sends a stop signal to the motor, the motor stops rotating, a solar panel 8 also stops rotating, and at the moment, the solar output power reaches the maximum.

The user of the automatic lifting control system can adjust the overall height of the solar panel 8 according to the requirement. When the ascending or descending button is pressed down, the controller sends a rotation command to the motor, and the solar panel 8 is driven to ascend and descend through mechanical transmission. When the solar panel is lifted or lowered to a certain required height, the motor stops rotating when the stop button is pressed, and the solar panel 8 also stops moving up and down. At the lifting extreme positions, namely the top and the bottom of the bracket 3, two ends of the bracket are respectively provided with an infrared receiving and transmitting device. For the lower part, the infrared rays can be accepted as a safe state, and when the infrared rays cannot be accepted, the program transmits a stop command to the motor and the solar panel 8 stops the up-and-down movement. For the upper part, the infrared ray cannot be accepted as the normal state, and when the infrared ray can be accepted, it indicates that the top position has been reached and cannot be raised any more, so the program sends a stop command.

Further, the control system further comprises: the device comprises an illumination intensity sensor, a photoelectric detector, a wind speed sensor and a solar cell panel parameter acquisition module. The basic principle of photoelectric tracking: the photodetector composed of the photosensitive elements is very sensitive to the change of the illumination intensity, and the output signal of the photodetector changes when the illumination intensity changes. In the tracking process, the position of the sun changes continuously, when the direct sunlight direction deviates from the main optical axis of the tracking device or a shadow is shielded, the output signal of the photoelectric detector changes, the change is transmitted to the controller through the processes of filtering, amplifying, I/V conversion and the like, the controller program sends out different control commands according to different signals, the motor is driven to rotate, the direction of the tracking device is changed, and the tracking device stops until the photoelectric detector is aligned with the sun again.
