[0013] In some embodiments, based on the true solar time, calculating the optimal angle that the solar panel array needs to be adjusted, and adjusting the solar panel array based on the optimal angle includes: inputting the true solar time into the solar hour angle calculation formula to calculate the solar hour angle of the sun's rays; calculating the optimal angle of the solar panel array based on the solar hour angle, wherein the solar panel array is perpendicular to the sun's rays at the optimal angle; calculating the angle difference between the elevation angle of the solar panel array and the optimal angle; and when the angle difference is greater than a preset angle threshold, adjusting the elevation angle of the solar panel array to the optimal angle.

[0015] Through the above technical solution, the solar panel array elevation angle control system provided by the present invention detects the elevation angle of the solar panel array through an angle sensor, calculates the optimal angle of the solar panel array through a central control module, and then compares the elevation angle with the optimal angle, thereby being able to determine whether the elevation angle of the solar panel array is at the optimal angle, and adjust the elevation angle, thereby ensuring that the solar panels remain at the optimal light receiving angle to improve the efficiency of solar energy collection and conversion.

[0030] Figure 1 is a schematic diagram of the structure of a solar panel array elevation control system disclosed in an embodiment of the present disclosure, such as Figure 1 As shown, the system includes: an angle adjustment mechanism connected to the solar panel array 5 and used to adjust the elevation angle of the solar panel array 5; an angle sensor, arranged on the angle adjustment mechanism, used to detect the elevation angle of the solar panel array 5 and feed the elevation angle back to the central control module; and a central control module, connected to the angle adjustment mechanism, used to calculate the optimal angle of the solar panel array 5, and issue a control instruction to the angle adjustment mechanism based on the difference between the elevation angle and the optimal angle.

[0031] Figure 2 is a schematic diagram of the structure of the angle adjustment mechanism disclosed in the embodiment of the present disclosure, such as Figure 2 As shown, the solar panel array 5 is composed of a plurality of solar panels, the surface of which is covered with photovoltaic materials for converting sunlight into electrical energy. The plurality of solar panels are fixedly connected to the angle adjustment mechanism, for example, by bolts, and rotate with the angle adjustment mechanism.

[0032] Among them, the angle sensor can be a high-precision sensor such as a photoelectric encoder, a magnetic encoder or a gyroscope.

[0033] In the system provided by the present disclosure, the elevation angle control system of the solar panel array 5 detects the elevation angle of the solar panel array 5 through an angle sensor, calculates the optimal angle of the solar panel array 5 through a central control module, and then compares the actual elevation angle with the calculated optimal angle, thereby being able to determine whether the elevation angle of the solar panel array 5 is at the optimal angle, and adjusting the elevation angle through an angle adjustment mechanism, thereby ensuring that the solar panels remain at the optimal light receiving angle to improve the efficiency of solar energy collection and conversion.

[0034] In addition, the system provided by the present disclosure has a simple design, convenient operation, and a high degree of automation, which greatly reduces the need for manual intervention and facilitates subsequent maintenance and upgrades.

[0035] Please refer to Figure 2 In some embodiments, the angle adjustment mechanism includes: a solar panel fixing frame 1, used to fix the solar panel on the solar panel fixing frame 1; a supporting base frame 2, connected to the solar panel fixing frame 1, used to support the solar panel fixing frame 1; and an electric cylinder assembly 3, connected to the solar panel fixing frame 1, used to adjust the elevation angle of the solar panel fixing frame 1, thereby adjusting the elevation angle of the solar panel array 5.

[0036] The supporting frame 2 is connected to the solar panel fixing frame 1 via high-strength bolts of the middle bearing seat to improve the stability of the entire solar panel fixing frame 1. Figure 3 Schematic diagram of the angle adjustment mechanism disclosed in the embodiment of the present disclosure. Figure 3 As shown, the electric cylinder assembly 3 can drive the solar panel to adjust a large angle by extending and shortening. In some embodiments, the angle adjustment range is 30°-150°. In other embodiments of the present invention, the angle adjustment can also be in other ranges according to the connection relationship between the various components of the angle adjustment mechanism.

[0037] In some embodiments, an angle sensor is disposed on the solar panel fixing frame 1 to monitor and feedback the current angle information of the solar panel array 5 in real time.

[0038] In some embodiments, the electric cylinder assembly 3 includes: a controller, used to receive control instructions issued by the central control module and control the motor; a motor, used to provide power to the electric cylinder assembly 3; a reducer, connected to the motor, used to adjust the force applied by the motor to the electric cylinder push rod; and a transmission mechanism, including an electric cylinder push rod, connected to the solar panel fixing frame 1, and the elevation angle of the solar panel fixing frame 1 is adjusted by the motor control.

[0039] It should be noted that the motor output speed is often very high and the torque is low, so a planetary reducer is required to reduce the motor speed and increase the torque, so that the force acting on the electric cylinder push rod meets the required requirements. In addition, to ensure the accuracy and stability of the adjustment, the motor should use a high-precision stepper motor or servo motor and be equipped with a corresponding encoder for position feedback. The encoder can calculate the push-out length of the electric cylinder push rod based on the motor speed and running time for position feedback, so that the electric cylinder assembly 3 can adjust the elevation angle of the solar panel array 5 more accurately.

[0040] Please refer to Figure 2 and Figure 3 In some embodiments, the angle adjustment mechanism further includes a protective cover 4, which is arranged outside the motor and is used to protect the motor and other components of the electric cylinder assembly 3 to prevent the motor and other components from getting wet and being exposed to the sun for a long time.

[0041] In some embodiments, the central control module includes: a host computer, including a GPS module, for obtaining the installation location of the system and the true solar time of the installation location, and sending them to a processor; and a processor, for calculating the optimal angle that the solar panel array 5 needs to be adjusted based on the true solar time, and issuing control instructions to the angle adjustment mechanism.

[0042] The processor may be an embedded processor, which is arranged on the angle adjustment mechanism. In other embodiments of the present invention, other processors may be selected according to actual production conditions, and the present invention is not limited thereto.

[0043] It should be noted that, when calculating time, Beijing time is often used instead of local time (true solar time). However, at the same Beijing time, the angle of sunlight is different in different regions. Therefore, the system proposed in the present disclosure is provided with a GPS module to obtain the true solar time of the location where the system is installed, and then the true solar time is used to calculate the optimal angle that the solar panel array 5 needs to be adjusted, thereby improving the accuracy of the calculation result.

[0044] It is understandable that in a short period of time, the sunlight will not change significantly, so there is no need to calculate in real time the optimal angle that the solar panel array 5 needs to be adjusted to. It only needs to be calculated and adjusted once every preset time period. The preset time period can be set to half an hour, or set to other time periods according to actual conditions.

[0045] Among them, the host computer is also used to display and set relevant parameters, such as displaying the actual elevation angle of the solar panel array 5 and the calculated optimal angle, and setting and displaying the preset duration. In addition, the host computer is also used to determine whether the angle adjustment mechanism is working properly and perform automatic repair. When the angle adjustment mechanism cannot work properly, for example, after the angle adjustment mechanism is adjusted, the actual elevation angle of the solar panel array 5 is abnormal. At this time, the host computer determines that the angle adjustment mechanism cannot work properly, automatically restarts the central control module, and re-adjusts the elevation angle of the solar panel array 5. When the central control module restarts a preset number of times, for example, three times, the actual elevation angle of the solar panel array 5 is still adjusted abnormally, and the host computer determines that the system fault cannot be automatically repaired. At this time, the host computer sends an alarm signal to the maintenance personnel to remind the maintenance personnel to repair the system in time. This fault diagnosis and automatic repair function improves the overall stability and reliability of the system and reduces the downtime caused by faults.

[0046] In some embodiments, based on the true solar time, calculating the optimal angle that the solar panel array 5 needs to be adjusted, and issuing a control instruction to the angle adjustment mechanism includes: inputting the true solar time into the solar hour angle calculation formula to calculate the solar hour angle of the sun's rays; calculating the optimal angle of the solar panel array 5 based on the solar hour angle, wherein the solar panel array 5 is perpendicular to the sun's rays at the optimal angle; calculating the angle difference between the elevation angle of the solar panel array 5 and the optimal angle; and when the angle difference is greater than a preset angle threshold, outputting the angle difference to the angle adjustment mechanism, so that the angle adjustment mechanism adjusts the elevation angle of the solar panel array 5 to the optimal angle based on the angle difference.

[0047] The calculation formula of solar hour angle is as follows:

[0048] ω=15×(ST-12),

[0049] Wherein, ω represents the solar hour angle, ST represents the true solar time at the location of the solar panel array 5, and in 24 hours, the angle of the earth's rotation per hour corresponds to the change of the solar hour angle, and the noon hour angle is defined as 0°, the morning hour angle is negative, and the afternoon hour angle is positive. The earth rotates 360 degrees, and the corresponding time is 24 hours, that is, the corresponding hour angle per hour is 15 degrees.

[0050] After calculating the solar hour angle, the angle difference between the elevation angle of the solar panel array 5 and the optimal angle is calculated. When the angle difference is greater than a preset angle threshold, such as 5° or 10°, it is considered that the elevation angle of the solar panel needs to be adjusted. The angle adjustment mechanism adjusts the elevation angle of the solar panel array 5 to the optimal angle based on the angle difference. In other embodiments of the present invention, the preset angle threshold may be set to other values ​​according to actual conditions, and the present invention is not limited thereto.

[0051] In some embodiments, after the angle adjustment mechanism adjusts the elevation angle of the solar panel array 5 to the optimal angle based on the angle difference, the angle adjustment mechanism controls the solar panel array 5 to swing within a preset swing range of the optimal angle, and searches for the elevation angle corresponding to the maximum power of instantaneous power generation within the preset swing range, and adjusts the elevation angle of the solar panel array 5 to the elevation angle corresponding to the maximum power.

[0052] In theory, when the sun's rays shine vertically onto the solar panel array 5, the power of photoelectric conversion can reach the maximum. However, due to calculation errors or other reasons, in reality, after the elevation angle of the solar panel array 5 is adjusted to the calculated optimal angle, the maximum photoelectric conversion power may not be reached. Therefore, the system proposed in the present disclosure sets a preset swing range. After calculating the optimal angle, the solar panel array 5 swings within a certain angle range before and after the optimal angle, such as a swing range of ±5° or ±10°, and then searches for the elevation angle corresponding to the maximum power of instantaneous power generation within the range. The elevation angle corresponding to the maximum power is the angle to be adjusted in the end, which further improves the conversion efficiency of solar energy. In other embodiments of the present invention, the preset swing range can also be set to other values ​​according to actual conditions, and the present invention is not limited thereto.

[0053] It should be noted that in the early morning or evening, the solar hour angle is near the maximum or minimum value, the light intensity is low, and the adjustment of the elevation angle of the solar panel array 5 will not significantly improve the power generation efficiency. Therefore, the angle adjustment range of the solar panel array 5 does not have to completely cover all values ​​of the solar hour angle. Figure 3 The angle adjustment range is 30°-150°. In the early morning or evening, when the sun angle is less than -60° or greater than 60°, the solar panel array 5 is fixed at Figure 3 The angle shown is sufficient, and adjustment can be made after the sunlight can shine vertically on the solar panel array 5.

[0054] In some embodiments, the system further includes a power management module, which includes: a main power supply, which uses the electric energy generated by the solar panel itself to power the system; and a backup power supply, which uses a battery to power the system.

[0055] The power management module is responsible for providing a stable and reliable power supply for the entire system. Considering the particularity of solar power stations, the power management module gives priority to using the electricity generated by the solar panels themselves as the main power source. At the same time, in order to cope with rainy days or nighttime conditions without light, batteries are equipped as a backup power source. The power management module also has functions such as power conversion, distribution and protection to ensure the normal operation of various components of the system. For example, the electricity generated by the solar panels first fills the power management module and then is transmitted to the external output system.

[0056] In some embodiments, the system also includes a communication module for realizing data transmission and remote control between various components within the system. The system can use wired or wireless communication methods (such as CAN bus, Zigbee, LoRa, etc.) for data transmission. At the same time, in order to facilitate remote monitoring and maintenance, the system also supports remote communication protocols (such as TCP / IP, MQTT, etc.) to exchange data and transmit instructions with the remote monitoring center.

[0062] In some embodiments, based on the true solar time, calculating the optimal angle to which the solar panel array 5 needs to be adjusted, and adjusting the solar panel array 5 based on the optimal angle includes: inputting the true solar time into the solar hour angle calculation formula to calculate the solar hour angle of the sun's rays; calculating the optimal angle of the solar panel array 5 based on the solar hour angle, wherein the solar panel array 5 is perpendicular to the sun's rays at the optimal angle; calculating the angle difference between the elevation angle of the solar panel array 5 and the optimal angle; and when the angle difference is greater than a preset angle threshold, adjusting the elevation angle of the solar panel array 5 to the optimal angle.

[0063] In some embodiments, after the elevation angle of the solar panel array 5 is adjusted to the optimal angle, the solar panel array 5 swings within a preset swing range of the optimal angle, and searches for the elevation angle corresponding to the maximum power at the instant of power generation within the preset swing range, and adjusts the elevation angle of the solar panel array 5 to the elevation angle corresponding to the maximum power.
