[0002] With the continuous growth of global energy demand and the increasing emphasis on environmental protection, solar energy, as a clean and renewable energy source, has great development potential. Photoelectric energy conversion technology provides an effective way to solve the energy crisis and reduce carbon emissions by directly converting solar energy into electrical energy. It can not only provide stable power supply for remote areas, but also be combined with the traditional power grid in cities to achieve distributed power generation. Therefore, photoelectric energy conversion is of great significance for promoting the optimization of the energy structure and sustainable development.

[0003] Currently, most existing photoelectric energy conversion systems are installed in a fixed manner and cannot adjust the angle in real time according to the change of the sun's position, resulting in the solar energy reception efficiency of solar photovoltaic units being much lower than the theoretical maximum value for most of the time, and the maximum utilization of solar energy cannot be achieved.

[0004] Although the traditional method can achieve photoelectric energy conversion, it cannot improve the photoelectric conversion efficiency by tracking and precisely adjusting the sun's position in real time, especially when the light intensity changes greatly, it is difficult to adapt quickly and its flexibility is difficult to play. Therefore, the efficiency and flexibility of photoelectric energy conversion need to be improved. Summary of the Invention

[0015] To achieve the above object, the present invention also provides a photoelectric energy conversion system based on a linear actuator, including: A tracking status confirmation module, configured to receive a photoelectric energy conversion instruction and start a pre-confirmed photoelectric energy conversion system based on the photoelectric energy conversion instruction.

[0016] To solve the above problems, the present invention further provides an electronic device, where the electronic device includes: A memory, storing at least one instruction; and a processor, executing the instruction stored in the memory to implement the above-mentioned photovoltaic energy conversion method based on a linear actuator.

[0017] To solve the above problems, the present invention further provides a computer-readable storage medium, where at least one instruction is stored in the computer-readable storage medium, and the at least one instruction is executed by a processor in an electronic device to implement the above-mentioned photovoltaic energy conversion method based on a linear actuator.

[0018] To solve the problems described in the background art, the present invention receives a photo - electric energy conversion instruction and starts a pre - confirmed photo - electric energy conversion system based on the photo - electric energy conversion instruction. The photo - electric energy conversion system includes: a light detection unit, a positioning unit, a linear drive biaxial tracking unit, an angle monitoring unit, and a solar photovoltaic unit. After the light detection unit confirms that the photo - electric energy conversion system enters a preset tracking state, the positioning unit is started. It can be seen that the present invention intelligently judges the working state of the photo - electric energy conversion system by dynamically monitoring the light intensity. This adaptive mechanism enables the photo - electric energy conversion system to flexibly switch to the tracking state or the low - efficiency state when the light conditions change, ensuring that the photo - electric conversion efficiency is always at the optimal level. The present invention obtains the running time of the photo - electric energy conversion system in real time to get the monitoring time. When the monitoring time reaches the preset tracking start time, the started positioning unit is used to obtain the solar spatial position, where the solar spatial position includes the solar altitude angle and the solar azimuth angle.

Within the preset tracking cut - off time, the adjustment distance set and the linear drive biaxial tracking unit are used to adjust the spatial position of the solar photovoltaic unit. It can be seen that the present invention improves the tracking accuracy of the solar photovoltaic unit by dynamically adjusting the tracking time interval and reducing the errors caused by different environmental and seasonal changes. At the same time, the compensation angle set is monitored and calculated in real time to correct the angle deviation caused by the total time used in the tracking process from obtaining the solar spatial position to completing the angle adjustment of the photo - electric energy conversion system. Combining the tracking time interval and the compensation angle set, the adjustment distance set is accurately calculated to ensure that the solar photovoltaic unit is always aligned with the sun, maximizing the photo - electric conversion efficiency. After the present invention confirms that the adjustment of the solar photovoltaic unit is completed, an adjustment angle set is obtained based on the angle monitoring unit, where the adjustment angle set includes an adjustment altitude angle and an adjustment azimuth angle. Based on the adjustment angle set and the photo - electric energy conversion system, a target power supply system is obtained. It can be seen that the present invention dynamically adjusts the power supply mode according to the real - time change of the photo - electric energy conversion power, ensuring the stable operation of the photo - electric energy conversion system under different light conditions on the basis of maximizing the utilization of solar energy. Therefore, the present invention can improve the efficiency and flexibility of photo - electric energy conversion. Description of the Drawings

[0021] The implementation, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0022] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The embodiments of the present application provide a photoelectric energy conversion method based on a linear actuator. The execution subject of the photoelectric energy conversion method based on the linear actuator includes, but is not limited to, at least one of electronic devices such as a server, a terminal, etc. that can be configured to execute the method provided by the embodiments of the present application. In other words, the photoelectric energy conversion method based on the linear actuator can be executed by software or hardware installed on a terminal device or a server device, and the software can be a blockchain platform. The server includes, but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, etc.

[0024] Refer to Figure 1 As shown, it is a schematic flowchart of a photoelectric energy conversion method based on a linear actuator provided by an embodiment of the present invention. In this embodiment, the photoelectric energy conversion method based on the linear actuator includes: S1. Receive a photoelectric energy conversion instruction, and start a pre - confirmed photoelectric energy conversion system based on the photoelectric energy conversion instruction. Among them, the photoelectric energy conversion system includes: a light detection unit, a positioning unit, a linear drive biaxial tracking unit, an angle monitoring unit, and a solar photovoltaic unit.

[0025] It is understandable that the photovoltaic energy conversion instruction is a control signal that triggers the operation of the photovoltaic energy conversion system and is used to start the photovoltaic energy conversion system. The light detection unit is a sensor device for real-time monitoring of the solar light intensity. Optionally, a light sensor of model BH1750 is used as the light detection unit, and the same effect can be achieved by using light sensors of other models, which will not be elaborated here. The positioning unit is used to determine the spatial position of the sun. Optionally, a GPS module of model u-blox NEO-6M is used as the positioning unit and combined with astronomical algorithms to obtain the spatial position of the sun. This process can be achieved by using other technologies, which will not be elaborated here. The linear drive two-axis tracking unit is a mechanical device for adjusting the position of the solar photovoltaic unit in the horizontal and vertical directions to ensure that the solar photovoltaic unit is always aligned with the sun and maximize the utilization efficiency of solar energy. The linear drive two-axis tracking unit includes two groups of linear actuators, namely the horizontal linear actuator and the vertical linear actuator. The horizontal linear actuator is used to adjust the azimuth angle of the photovoltaic module so that it is always aligned with the sun in the horizontal direction, and the vertical linear actuator is used to adjust the elevation angle of the photovoltaic module so that it is always aligned with the sun in the vertical direction. The angle monitoring unit is used to measure the actual elevation angle and azimuth angle of the solar photovoltaic unit in real time, and can provide real-time angle data for the photovoltaic energy conversion system for closed-loop control and error correction. The angle monitoring unit is a sensor for measuring the spatial position of the solar photovoltaic unit, which can be a single type of sensor or a combination of multiple sensors. Optionally, an IMU is used as the angle monitoring unit to obtain the spatial position of the solar photovoltaic unit. The solar photovoltaic unit includes a solar power supply unit and a photoelectric conversion unit. The role of the photoelectric conversion unit is to convert solar energy into electrical energy, and the solar power supply unit is a storage unit for storing the converted electrical energy separately.

[0026] S2. After confirming that the photovoltaic energy conversion system enters the preset tracking state based on the light detection unit, start the positioning unit.

[0027] It should be explained that after confirming that the photovoltaic energy conversion system enters the preset tracking state based on the light detection unit, it includes: When the monitoring time reaches the preset night period, the operation mode of the photovoltaic energy conversion system is switched to the preset night mode; otherwise, the operation mode of the photovoltaic energy conversion system is switched to the preset working mode. After confirming that the operation mode of the photovoltaic energy conversion system is the working mode, the preset daytime period is divided into a sub-period sequence based on the preset evaluation frequency. Among them, the sub-period sequence includes multiple sub-periods, and the sub-period is composed of a detection period and an execution period. When the monitoring time reaches the detection period of the sub-period, taking the sub-period as the initial sub-period, within the detection period, based on the light detection unit and the preset light detection frequency, obtain a light intensity sequence, where the light intensity sequence includes multiple light intensity values, and the working states of the photovoltaic energy conversion system include an inefficient state and a tracking state; Based on the initial sub-period, identify a reference sub-period in the sub-period sequence, where the reference sub-period is adjacent to and lags behind the initial sub-period; Obtain the light intensity change rate and the average light intensity based on the light intensity sequence; Compare the light intensity change rate with the preset light intensity change rate threshold and the average light intensity with the preset light intensity threshold respectively; If the light intensity change rate is less than or equal to the light intensity change rate threshold and the average light intensity is less than or equal to the light intensity threshold, confirm the working state of the photovoltaic energy conversion system as the inefficient state, otherwise, confirm the working state of the photovoltaic energy conversion system as the tracking state until the monitoring time reaches the execution period of the reference sub-period.

[0028] It can be understood that the preset night period is a period of time set artificially considering the geographical location of the photovoltaic conversion system and the current season. During this period, the light intensity is insufficient and the photovoltaic energy conversion system cannot perform photovoltaic energy conversion. The preset night mode refers to a low-power operation state that the photovoltaic energy conversion system enters during the night period. In this mode, the photovoltaic energy conversion system will turn off the linear drive two-axis tracking unit, the angle monitoring unit, and the solar photovoltaic unit to reduce energy consumption. The preset working mode refers to the normal working state that the photovoltaic energy conversion system enters under sufficient light intensity. In this mode, all units of the photovoltaic energy conversion system are in the on state to perform photovoltaic conversion. The daytime period refers to the time range during which the photovoltaic energy conversion system is in the working mode, usually starting from sunrise to sunset.

[0029] It should be understood that the sub-time period sequence is a smaller time period obtained by dividing the daylight period according to a preset evaluation frequency. Each sub-time period includes a detection period and an execution period. The evaluation frequency is the time interval frequency for dividing the daylight period into multiple sub-time periods. The detection period is the time period within the sub-time period for performing light detection. During this period, the system obtains a light intensity sequence through the light detection unit and the preset light detection frequency. The execution period is the time period for implementing specific operations based on the evaluation result of the detection period. The specific operation here refers to the operation of confirming the photovoltaic energy conversion system as an inefficient state or a tracking state. The light intensity sequence is a time sequence containing multiple light intensity values, used to describe the change of light intensity during the detection period. The light intensity value refers to the light intensity value measured by the light detection unit at the location of the solar photovoltaic unit. The light detection frequency refers to the time interval frequency at which the light detection unit obtains the light intensity value during the detection period of the sub-time period.

[0030] Exemplarily, assume that the daylight period on a certain day is from 7:00:00 am to 5:00:00 pm, and the evaluation frequency is once every hour. Therefore, each sub-period is 1 hour, and the daylight period is divided into 10 sub-periods. Taking the initial sub-period from 7:00:00 to 8:00:00 as an example, its preset detection period is from 7:00:00 to 7:10:00, and the preset execution period is from 7:10:00 to 8:00:00. The reference sub-period is from 8:00:00 to 9:00:00, and its corresponding detection period is from 8:00:00 to 8:10:00, and the execution period is from 8:10:00 to 9:00:00. If the light intensity sequence obtained during the detection period of the initial sub-period (from 7:00:00 to 7:10:00) meets the confirmation conditions of the tracking state, then during the period from the start time of the execution period of the initial sub-period (7:10:00) to the start time of the execution period of the reference sub-period (8:10:00), the working state of the photovoltaic energy conversion system is confirmed as the tracking state. Here, the confirmation process can be to switch or not to perform an action. At the same time, during the detection period of the reference sub-period (from 8:00:00 to 8:10:00), the light detection unit is used again to obtain the light intensity sequence corresponding to the reference sub-period and determine whether it meets the confirmation conditions of the tracking state. If it does not meet the confirmation conditions of the tracking state, then during the period from the start time of the execution period of the reference sub-period (8:10:00) to the start time of the execution period of the next sub-period of the reference sub-period (9:10:00), the working state of the photovoltaic energy conversion system is confirmed as the low-efficiency state. Among them, the confirmation conditions of the tracking state are: the light intensity change rate is greater than the light intensity change rate threshold and the average light intensity is greater than the illuminated intensity threshold. As long as any one of the two conditions is met. The low-efficiency state is a low-power operation state entered by the photovoltaic energy conversion system when the light conditions are relatively weak but still can perform low-efficiency photovoltaic conversion. In this state, the photovoltaic energy conversion system remains in a better position for photovoltaic energy conversion, but the output power is low. The tracking state is a high-efficiency operation state entered by the photovoltaic energy conversion system when the light conditions are ideal. By dynamically adjusting the angle of the solar photovoltaic unit, the light is received maximally to achieve efficient photovoltaic conversion.

[0031] It can be understood that the average light intensity is the average value of all light intensity values in the light intensity sequence, and the light intensity change rate represents the change rate of the light intensity. Exemplarily, the acquisition process of the light intensity change rate is as follows: Assume that the light intensity sequence is {300 lx, 310 lx, 315 lx, 330 lx, 350 lx, 400 lx}, and the time interval between every two adjacent light intensity values is 10 seconds. Then the corresponding light intensity change rate is (310 - 300 + 315 - 310 + 330 - 315 + 350 - 330 + 400 - 350) / (5 10) The absolute value of d. The light intensity change rate threshold is a manually set change rate threshold used to determine whether the light intensity change rate meets the requirements for the photovoltaic energy conversion system to enter the tracking state. The light intensity threshold is a manually preset light intensity value used to determine whether the current actual light conditions meet the requirements for the photovoltaic energy conversion system to enter the tracking state. In the embodiments of the present invention, the working state of the photovoltaic energy conversion system is intelligently switched by dynamically monitoring the light intensity. This adaptive mechanism enables the photovoltaic energy conversion system to flexibly switch to the tracking state or the low-efficiency state when the light conditions change, ensuring that the photovoltaic conversion efficiency is always at the optimal level.

[0032] S3. Obtain the running time of the photovoltaic energy conversion system in real time to obtain the monitoring time. When the monitoring time reaches the preset tracking start time, use the activated positioning unit to obtain the solar spatial position, where the solar spatial position includes the solar altitude angle and the solar azimuth angle.

[0033] It can be understood that the monitoring time is the running time of the photovoltaic energy conversion system recorded in real time. The solar spatial position refers to the specific position of the sun in the sky, usually determined by two parameters, the solar altitude angle and the solar azimuth angle, and is used to describe the vertical and horizontal positions of the sun relative to the ground with the solar photovoltaic unit as the observation point. Optionally, a GPS module with the model u-blox NEO-6M is used as the positioning unit and combined with astronomical algorithms to obtain the solar spatial position, which is prior art and will not be elaborated here.

[0034] S4. Obtain an adjustment distance set based on the solar spatial position, where the adjustment distance set includes a horizontal adjustment distance and a vertical adjustment distance. Within the preset tracking cut-off time, use the adjustment distance set and the linear drive biaxial tracking unit to adjust the spatial position of the solar photovoltaic unit.

[0035] It should be explained that obtaining the adjustment distance set based on the solar spatial position includes: Taking the solar altitude angle in the solar spatial position as the target altitude angle and the solar azimuth angle in the solar spatial position as the target azimuth angle; Obtaining the initial altitude angle and the initial azimuth angle based on the angle monitoring unit and the solar photovoltaic unit; Obtaining a compensation angle set based on the photovoltaic energy conversion system, where the compensation angle set includes: a compensation altitude angle and a compensation azimuth angle; Calculating the vertical adjustment distance based on the initial altitude angle, the target altitude angle, the compensation altitude angle, and a pre-constructed vertical distance calculation formula, where the vertical distance calculation formula is as follows: ; Where represents the vertical adjustment distance, represents the target altitude angle, represents the latitude of the geographical location where the solar photovoltaic unit is located, represents the solar declination angle, represents the hour angle, represents the initial altitude angle, represents the change amount of the initial altitude angle of the solar photovoltaic unit when the linear drive two-axis tracking unit moves one unit length in the vertical direction, represents the compensation altitude angle; Calculate the horizontal adjustment distance based on the initial azimuth angle, the target azimuth angle, the compensation azimuth angle and a pre-constructed horizontal distance calculation formula. The horizontal distance calculation formula is as follows: ; wherein, represents the horizontal adjustment distance, represents the initial azimuth angle, represents the change amount of the initial azimuth angle of the solar photovoltaic unit when the linear drive two-axis tracking unit moves one unit length in the horizontal direction, represents the target azimuth angle, represents the compensation azimuth angle; Summarize the horizontal adjustment distance and the vertical adjustment distance to obtain an adjustment distance set.

[0036] It can be understood that the initial altitude angle is the current actual altitude angle of the solar photovoltaic unit, which is usually used to describe the current orientation of the solar photovoltaic unit in the vertical direction. The target altitude angle is the altitude angle to which the solar photovoltaic unit needs to be adjusted to maximize the tracking efficiency of the sun. The initial azimuth angle is the orientation angle of the solar photovoltaic unit in the current horizontal direction, reflecting the actual azimuth of the solar photovoltaic unit relative to the geographical direction. The target azimuth angle is the horizontal orientation angle to which the solar photovoltaic unit needs to be adjusted to face the sun directly. The angle monitoring unit is a sensor used to measure the spatial position of the solar photovoltaic unit, which can be a single type of sensor or a combination of multiple sensors. Optionally, using an IMU as the angle monitoring unit can obtain the spatial position of the solar photovoltaic unit, which is prior art and will not be elaborated here.

[0037] Specifically, the obtaining of the compensation angle set based on the photovoltaic energy conversion system includes: When the monitoring time reaches a preset first tracking moment, use the positioning unit corresponding to the photovoltaic energy conversion system to obtain the first solar spatial position, where the first solar spatial position includes the first solar altitude angle and the first solar azimuth angle; Obtain the first tracking node based on the first tracking moment, the first solar altitude angle and the first solar azimuth angle; Obtain a second tracking moment based on the first tracking moment and a preset initial tracking time interval; When the monitoring time reaches the second tracking moment, use the positioning unit corresponding to the photovoltaic energy conversion system to obtain a second tracking node, where the second tracking node includes the second tracking moment, the second solar altitude angle, and the second solar azimuth angle; Obtain a tracking time interval based on the first tracking node and the second tracking node, and use the tracking time interval and the second tracking moment to obtain a third tracking moment; When the monitoring time reaches the third tracking moment, use the positioning unit corresponding to the photovoltaic energy conversion system to obtain a third tracking node, where the third tracking node includes the third tracking moment, the third solar altitude angle, and the third solar azimuth angle, and the third tracking moment is the tracking start moment; Obtain a compensation angle set based on the second tracking node and the third tracking node.

[0038] It can be understood that both the first tracking moment and the second tracking moment are specific moments, corresponding to the key time nodes of the solar photovoltaic unit in the initial calibration stage. The first tracking moment is the initial time point when the positioning unit starts and begins to track the sun's position, and the second tracking moment is the next tracking time point lagging behind the first tracking moment calculated based on the first tracking moment and the preset initial tracking time interval. The initial tracking time interval is the preset time interval at the start of tracking, used to determine the second tracking moment. At the first tracking moment and the second tracking moment, the photovoltaic energy conversion system calibrates the system by initially obtaining tracking data, providing a basis for subsequent formal tracking.

[0039] It should be understood that the monitoring time is the operating time of the photovoltaic energy conversion system obtained in real time, used to determine whether the preset first tracking moment, second tracking moment, and third tracking moment are reached. Exemplarily, assume that an execution period of the tracking state is from 7:10:00 am to 8:10:00 am on a certain day, with 7:10:00 as the first tracking moment and the initial tracking time interval set to 5 minutes, and the second tracking moment is obtained as 7:15:00. When the monitoring time reaches 7:10:00 am, use the positioning unit to obtain the sun's spatial position, obtaining the first sun spatial position, which is the first solar altitude angle and the first solar azimuth angle obtained at the first tracking moment. The first tracking node is the initial tracking node determined based on the sun's spatial position when the monitoring time reaches the first tracking moment, used to record and calculate the starting state of the sun tracking system. When the monitoring time reaches 7:15:00 am on the same day, use the positioning unit to obtain the sun's spatial position, obtaining the second tracking node, which is the tracking node determined based on the sun's spatial position when the monitoring time reaches the second tracking moment, used to record and calculate the state of the sun tracking system at the second tracking moment.

[0040] Further, obtaining the tracking time interval based on the first tracking node and the second tracking node includes: Calculating the absolute difference between the first solar altitude angle and the second solar altitude angle to obtain the absolute altitude angle difference, and obtaining the altitude angle change rate based on the absolute altitude angle difference and the initial tracking time interval, where the altitude angle change rate is the ratio of the absolute altitude angle difference to the initial tracking time interval; Calculating the absolute difference between the first solar azimuth angle and the second solar azimuth angle to obtain the absolute azimuth angle difference, and obtaining the azimuth angle change rate based on the absolute azimuth angle difference and the initial tracking time interval, where the azimuth angle change rate is the ratio of the absolute azimuth angle difference to the initial tracking time interval; Respectively comparing the altitude angle change rate with a preset altitude angle change rate threshold and the azimuth angle change rate with a preset azimuth angle change rate threshold; If the altitude angle change rate is greater than the altitude angle change rate threshold and the azimuth angle change rate is greater than the azimuth angle change rate threshold, using the initial tracking time interval as the tracking time interval; otherwise, using a preset updated tracking time interval as the tracking time interval.

[0041] It can be understood that the third tracking moment is a specific moment, marking the time of formal tracking. Different from the first tracking moment and the second tracking moment, the third tracking moment is a time point calculated based on the second tracking moment and the dynamically adjusted tracking time interval. This moment is the starting point for the optoelectronic energy conversion system to formally start tracking the sun position with the optimized time interval after completing the initial calibration. The first tracking moment and the second tracking moment are mainly used to obtain initial data to ensure that the optoelectronic energy conversion system can perform subsequent tracking tasks with higher accuracy and stability when the monitoring time reaches the third tracking moment.

[0042] It should be understood that the tracking time interval refers to the time interval used to dynamically adjust the tracking of the sun's position in the photovoltaic energy conversion system during the tracking process after the second tracking moment, so as to determine the time interval between two adjacent tracking moments. The change rate thresholds of the altitude angle and the azimuth angle are both artificially set change rate thresholds, which are respectively used to judge whether the change rates of the sun's altitude angle and azimuth angle per unit time meet the conditions for adjusting the tracking time interval. If the change rate of the sun's altitude angle is less than the change rate threshold of the altitude angle and the change rate of the sun's azimuth angle is less than the change rate threshold of the azimuth angle, it indicates that the change of the sun's position is slow, and the initial tracking time interval can continue to be used. Otherwise, a smaller updated tracking time interval needs to be adopted to improve the tracking accuracy. The third tracking node is the tracking node determined based on the sun's spatial position when the monitoring time reaches the third tracking moment, which is used to record and calculate the state of the sun tracking system at the third tracking moment, and the third tracking moment is the start moment of tracking. Similarly, the new tracking time interval after the third tracking moment can be obtained by using the data of the second tracking moment and the third tracking moment, and the fourth tracking moment can be obtained by using the new tracking time interval and the third tracking moment.

[0043] It should be explained that obtaining the compensation angle set based on the second tracking node and the third tracking node includes: Obtaining the tracking duration based on the start moment of tracking and the end moment of tracking; Calculating the compensation altitude angle based on the second tracking node, the third tracking node, the tracking duration and a pre-constructed compensation angle calculation formula, where the compensation angle calculation formula is as follows: ; Wherein, represents the compensation altitude angle, represents the second solar altitude angle represents the third solar altitude angle, represents the tracking time interval, represents the tracking duration; Obtaining the compensation azimuth angle based on the second tracking node and the third tracking node; Summarizing the compensation altitude angle and the compensation azimuth angle to obtain the compensation angle set.

[0044] It should be understood that the tracking start time is the starting point of formal tracking, and the cut-off time is a cut-off time point set according to experience, which is used to ensure that the angle corresponding to the solar photovoltaic unit is adjusted to face the sun as accurately as possible within the time range from the tracking start time to the cut-off time. The tracking time interval is the time interval between the tracking start time and the tracking cut-off time, which reflects the total time used in the tracking process of the photovoltaic energy conversion system from obtaining the solar spatial position to completing the angle adjustment. Completing the adjustment within the preset cut-off time means that the photovoltaic energy conversion system can quantify the errors in the entire tracking process. By combining the tracking time interval to calculate the changes in the solar altitude angle and azimuth angle, the photovoltaic energy conversion system can accurately calculate the angle deviation caused by the total delay generated in the processes of obtaining the solar spatial position, data processing, and angle adjustment, etc.

[0045] It can be understood that the compensation angle set is a set of compensation altitude angles and compensation azimuth angles, which is used to correct the angle deviation generated during the process of the solar photovoltaic unit tracking the sun, thereby improving the tracking accuracy. The compensation altitude angle is an angle value calculated to correct the deviation of the solar altitude angle. The compensation azimuth angle is an angle value calculated to correct the deviation of the solar azimuth angle. The compensation altitude angle and the compensation azimuth angle are respectively used to adjust the altitude angle and azimuth angle of the solar photovoltaic unit to make it more accurately aligned with the sun, thereby improving the tracking accuracy and the photovoltaic energy conversion efficiency. The horizontal adjustment distance refers to the actual distance that the linear drive biaxial tracking unit needs to move in the horizontal direction, which is a horizontal distance value calculated based on the initial azimuth angle, the target azimuth angle, and the compensation azimuth angle, and is used to adjust the azimuth angle of the solar photovoltaic unit to make it accurately aligned with the horizontal position of the sun. The vertical adjustment distance refers to the actual distance that the linear drive biaxial tracking unit needs to move in the vertical direction, which is a vertical distance value calculated based on the initial altitude angle, the target altitude angle, and the compensation altitude angle, and is used to adjust the altitude angle of the solar photovoltaic unit to make it accurately aligned with the vertical position of the sun. In the embodiment of the present invention, by dynamically adjusting the tracking time interval, the errors caused by different environmental and seasonal changes are reduced, thereby improving the tracking accuracy of the solar photovoltaic unit. At the same time, the compensation angle set is monitored and calculated in real time to correct the angle deviation generated during the tracking process of the photovoltaic energy conversion system. By combining the tracking time interval and the compensation angle set, the adjustment distance set is accurately calculated to ensure that the solar photovoltaic unit is always aligned with the sun, maximizing the photovoltaic energy conversion efficiency.

[0046] S5. After confirming that the adjustment of the solar photovoltaic unit is completed, based on the angle monitoring unit, obtain the adjustment angle set, where the adjustment angle set includes the adjustment altitude angle and the adjustment azimuth angle, and based on the adjustment angle set and the photovoltaic energy conversion system, obtain the target power supply system.

[0047] It should be understood that the adjusted elevation angle is the actual elevation angle of the solar photovoltaic unit measured by the angle monitoring unit after the linear drive two-axis tracking unit completes the adjustment of the solar photovoltaic unit, and it can be confirmed whether the solar photovoltaic unit has been adjusted to the optimal position in the vertical direction. The adjusted azimuth angle is the actual azimuth angle of the solar photovoltaic unit measured by the angle monitoring unit after the linear drive two-axis tracking unit completes the adjustment of the solar photovoltaic unit, and it can be confirmed whether the solar photovoltaic unit has been adjusted to the optimal position in the horizontal direction.

[0048] It should be explained that the obtaining of the target power supply system based on the adjusted angle set and the photovoltaic energy conversion system includes: Obtaining the compensated elevation angle based on the target elevation angle and the compensation elevation angle, where the compensated elevation angle is the sum of the target elevation angle and the compensation elevation angle; Obtaining the absolute elevation angle based on the compensated elevation angle and the adjusted elevation angle, where the absolute elevation angle is the absolute difference between the compensated elevation angle and the adjusted elevation angle; Obtaining the absolute azimuth angle based on the target azimuth angle, the compensation azimuth angle and the adjusted azimuth angle; Respectively comparing the absolute elevation angle with the preset elevation angle difference threshold and the absolute azimuth angle with the preset azimuth angle difference threshold; If the absolute elevation angle is less than the elevation angle difference threshold and the absolute azimuth angle is less than the azimuth angle difference threshold, obtaining the photovoltaic energy conversion power of the pre-constructed solar power supply unit, and using the photovoltaic energy conversion power to confirm the power supply mode of the photovoltaic energy conversion system to obtain the target power supply system; otherwise, adjusting the solar photovoltaic unit by using the pre-constructed adjustment method to obtain the target power supply system.

[0049] It can be understood that by monitoring the adjusted elevation angle and the adjusted azimuth angle, it can be confirmed whether the solar photovoltaic unit has been adjusted to the optimal position, so as to judge whether the tracking is successful. The elevation angle difference threshold refers to the maximum allowable deviation range between the adjusted elevation angle and the current solar elevation angle during the tracking process, and the azimuth angle difference threshold refers to the maximum allowable deviation range between the adjusted azimuth angle and the current solar azimuth angle during the tracking process. If the absolute difference between the adjusted elevation angle and the current solar elevation angle is less than the elevation angle difference threshold and the absolute difference between the adjusted azimuth angle and the current solar azimuth angle is less than the azimuth angle difference threshold, it indicates that the tracking is successful and the efficient conversion of photovoltaic energy is achieved; otherwise, it indicates that the tracking fails and needs to be readjusted.

[0050] Furthermore, the adjusting the solar photovoltaic unit by using the pre-constructed adjustment method to obtain the target power supply system includes: Obtaining the updated elevation angle based on the adjusted elevation angle and the preset elevation angle adjustment step; Obtaining the updated azimuth angle based on the adjusted azimuth angle and the preset azimuth angle adjustment step; Summarize and update the elevation angle and the updated azimuth angle to obtain an updated angle set, and use the updated angle set to adjust the solar photovoltaic unit to obtain an adjusted solar photovoltaic unit. Take the updated angle set corresponding to the adjusted solar photovoltaic unit as the adjustment angle set, and obtain the absolute azimuth angle and the absolute elevation angle based on the adjustment angle set, the target azimuth angle, the compensation azimuth angle, the target elevation angle, and the compensation elevation angle, and return to the step of respectively comparing the absolute elevation angle with a preset elevation angle difference threshold and the absolute azimuth angle with a preset azimuth angle difference threshold until the absolute elevation angle is less than the elevation angle difference threshold and the absolute azimuth angle is less than the azimuth angle difference threshold to obtain the target energy supply system.

[0051] It should be understood that the elevation angle adjustment step size is a fixed angle set for readjusting the elevation angle of the solar photovoltaic unit when a certain tracking fails but the next tracking time has not yet arrived, which is used to control the amplitude of the elevation angle adjustment to ensure that the solar photovoltaic unit gradually approaches the current solar elevation angle in the vertical direction. Similarly, the azimuth angle adjustment step size is a fixed angle set for readjusting the azimuth of the solar photovoltaic unit when a certain tracking fails but the next tracking time has not yet arrived, which is used to control the amplitude of the azimuth adjustment to ensure that the solar photovoltaic unit gradually approaches the current solar azimuth angle in the horizontal direction. Generally, the elevation angle adjustment step size can be a fixed value or a value dynamically adjusted according to the actual difference between the adjusted elevation angle and the current solar elevation angle. Similarly, the azimuth angle adjustment step size can be a fixed value or a value dynamically adjusted according to the actual difference between the adjusted azimuth angle and the current solar azimuth angle.

[0052] It can be understood that the updated elevation angle refers to the new elevation angle value obtained by adjusting based on the elevation angle adjustment step size on the basis of the current adjusted elevation angle. The updated azimuth angle refers to the new azimuth angle value obtained by adjusting based on the azimuth angle adjustment step size on the basis of the current adjusted azimuth angle.

[0053] Specifically, the step of using the photoelectric energy conversion power to confirm the power supply mode of the photoelectric energy conversion system to obtain the target energy supply system includes: Compare the photoelectric energy conversion power with a preset tracking power threshold and a preset starting power threshold, where the tracking power threshold is greater than the starting power threshold; If the photoelectric energy conversion power is less than the starting power threshold, use a pre-constructed traditional power supply unit to supply power to the photoelectric energy conversion system to obtain the target energy supply system; If the photoelectric energy conversion power is greater than the tracking power threshold, use the solar power supply unit to supply power to the photoelectric energy conversion system to obtain the target energy supply system; If the photoelectric energy conversion power is between the startup power threshold and the tracking power threshold, the solar power supply unit is used to supply power to the photoelectric energy conversion system, and the monitored conversion power of the solar power supply unit is obtained in real time. When the monitored conversion power is less than the startup power threshold, the traditional power supply unit is used to supply power to the photoelectric energy conversion system to obtain the target power supply system.

[0054] It can be understood that the solar photovoltaic unit includes a solar power supply unit and a photoelectric conversion unit. The role of the photoelectric conversion unit is to convert solar energy into electrical energy, and the solar power supply unit is a storage unit that stores the converted electrical energy separately. The traditional power supply unit is a power supply system based on non-renewable energy, which is used to provide stable power support when the solar power supply unit cannot meet the requirements of the photoelectric energy conversion system. It is usually used as a backup power supply to ensure that the photoelectric energy conversion system can still operate normally when the photoelectric energy conversion power is insufficient. When it is confirmed that the tracking is successful, it indicates that the current light condition is sufficient and a part of the photoelectric energy conversion power has been obtained by using the photoelectric conversion unit and stored in the solar power supply unit. The photoelectric energy conversion power is the electrical energy stored after the photoelectric conversion unit of the solar photovoltaic unit converts light energy. The startup power threshold refers to the minimum power level required for the photoelectric energy conversion system to start normal operation. The tracking power threshold refers to the power level required for the photoelectric energy conversion system to operate normally and achieve an efficient tracking function. The tracking power threshold is higher than the startup power threshold. The target power supply system is a dynamically switched power supply system that can select the most suitable power supply method to supply power to the photoelectric energy conversion system according to the comparison result between the photoelectric energy conversion power and the preset threshold, maximizing the use of solar energy to supply power to the photoelectric energy conversion system.

[0055] Exemplarily, when the photoelectric energy conversion power is less than the startup power threshold, the photoelectric energy conversion system cannot operate normally using the photoelectric energy conversion power of the solar power supply unit, so it switches to the traditional power supply unit to ensure the operation of the photoelectric energy conversion system. When the photoelectric energy conversion power is greater than the tracking power threshold, the photoelectric energy conversion system can rely entirely on the photoelectric energy conversion power generated by the solar power supply unit to operate efficiently and achieve efficient tracking. When the photoelectric energy conversion power is between the startup power threshold and the tracking power threshold, the photoelectric energy conversion power generated by the solar power supply unit is preferentially used for operation and the remaining photoelectric energy conversion power is monitored. When the photoelectric energy conversion power further drops below the startup power threshold, it switches to the traditional power supply unit to ensure the continuous operation of the photoelectric energy conversion system. By dynamically adjusting the power supply method according to the real-time change of the photoelectric energy conversion power, the embodiment of the present invention ensures the stable operation of the photoelectric energy conversion system under different light conditions on the basis of maximizing the use of solar energy.

[0056] To solve the problems described in the background art, the present invention receives a photo - electric energy conversion instruction and starts a pre - confirmed photo - electric energy conversion system based on the photo - electric energy conversion instruction. The photo - electric energy conversion system includes: a light detection unit, a positioning unit, a linear drive biaxial tracking unit, an angle monitoring unit, and a solar photovoltaic unit. After the light detection unit confirms that the photo - electric energy conversion system enters a preset tracking state, the positioning unit is started. It can be seen that the present invention intelligently judges the working state of the photo - electric energy conversion system by dynamically monitoring the light intensity. This adaptive mechanism enables the photo - electric energy conversion system to flexibly switch to the tracking state or the low - efficiency state when the light conditions change, ensuring that the photo - electric conversion efficiency is always at the optimal level. The present invention obtains the running time of the photo - electric energy conversion system in real time to get the monitoring time. When the monitoring time reaches the preset tracking start time, the started positioning unit is used to obtain the solar spatial position, where the solar spatial position includes the solar altitude angle and the solar azimuth angle. Based on the solar spatial position, an adjustment distance set is obtained, where the adjustment distance set includes a horizontal adjustment distance and a vertical adjustment distance. Within the preset tracking cut - off time, the adjustment distance set and the linear drive biaxial tracking unit are used to adjust the spatial position of the solar photovoltaic unit. It can be seen that the present invention reduces the errors caused by different environmental and seasonal changes by dynamically adjusting the tracking time interval, thereby improving the tracking accuracy of the solar photovoltaic unit. At the same time, the compensation angle set is monitored and calculated in real time to correct the angle deviation caused by the total time used in the tracking process from obtaining the solar spatial position to completing the angle adjustment of the photo - electric energy conversion system. Combining the tracking time interval and the compensation angle set, the adjustment distance set is accurately calculated to ensure that the solar photovoltaic unit is always aligned with the sun, maximizing the photo - electric conversion efficiency. After the present invention confirms that the adjustment of the solar photovoltaic unit is completed, based on the angle monitoring unit, an adjustment angle set is obtained, where the adjustment angle set includes an adjustment altitude angle and an adjustment azimuth angle. Based on the adjustment angle set and the photo - electric energy conversion system, a target power supply system is obtained. It can be seen that the present invention dynamically adjusts the power supply mode according to the real - time change of the photo - electric energy conversion power, ensuring the stable operation of the photo - electric energy conversion system under different light conditions on the basis of maximizing the utilization of solar energy. Therefore, the present invention can improve the efficiency and flexibility of photo - electric energy conversion.
