Description

Technical Field

[0001] The present invention relates to the field of new energy and mechanical engineering technology, and in particular to a photoelectric energy conversion method and system based on a linear actuator. Background Art

[0002] With the continuous growth of global energy demand and the increasing emphasis on environmental protection, solar energy, as a clean, renewable energy source, holds enormous development potential. Photovoltaic energy conversion technology, by directly converting solar energy into electricity, offers an effective approach to addressing the energy crisis and reducing carbon emissions. It not only provides a stable power supply to remote areas but can also be integrated with traditional power grids in cities to achieve distributed power generation. Therefore, photovoltaic energy conversion plays a crucial role in promoting energy mix optimization and sustainable development.

[0003] Currently, most existing photovoltaic energy conversion systems are fixedly installed and cannot adjust their angles in real time according to changes in the sun's position. As a result, the solar energy receiving efficiency of solar photovoltaic units is far below the theoretical maximum for most of the time, making it impossible to maximize the use of solar energy.

[0004] While traditional methods can achieve photovoltaic energy conversion, they cannot improve efficiency by tracking the sun's position in real time and accurately adjusting it. In particular, they cannot adapt quickly to large changes in light intensity, making it difficult to achieve full flexibility. Therefore, the efficiency and flexibility of photovoltaic energy conversion need to be improved. Summary of the Invention

[0069] In order to solve the above problems, the present invention also provides a computer-readable storage medium, which stores at least one instruction. The at least one instruction is executed by a processor in an electronic device to implement the above-mentioned photoelectric energy conversion method based on a linear actuator.

[0070] The present invention addresses the problems described in the background art. It receives a photovoltaic energy conversion instruction and, based on the instruction, activates a pre-confirmed photovoltaic energy conversion system. The photovoltaic energy conversion system comprises: a light detection unit, a positioning unit, a linear-driven dual-axis tracking unit, an angle monitoring unit, and a solar photovoltaic unit. After the light detection unit confirms that the photovoltaic energy conversion system has entered a preset tracking state, the positioning unit is activated. The present invention intelligently determines the operating state of the photovoltaic energy conversion system by dynamically monitoring light intensity. This adaptive mechanism enables the photovoltaic energy conversion system to flexibly switch between a tracking state and a low-efficiency state when lighting conditions change, ensuring that photovoltaic conversion efficiency remains at an optimal level. The present invention obtains the operating time of the photovoltaic energy conversion system in real time to obtain a monitoring time.

Based on the solar spatial position, an adjustment distance set is obtained, which includes a horizontal adjustment distance and a vertical adjustment distance. Within a preset tracking end time, the adjustment distance set and the linear-driven dual-axis tracking unit are used to adjust the spatial position of the solar photovoltaic unit. It can be seen that the present invention reduces errors caused by different environments 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 by the photovoltaic energy conversion system in the tracking process from obtaining the spatial position of the sun to completing the angle adjustment. 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 and maximize the photovoltaic energy conversion efficiency.

It can be seen that the present invention dynamically adjusts the power supply mode according to the real-time changes in the amount of photovoltaic energy converted, and ensures that the photovoltaic energy conversion system can operate stably under different lighting conditions on the basis of maximizing the use of solar energy. Therefore, the present invention can improve the efficiency and flexibility of photovoltaic energy conversion. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0078] This embodiment of the present application provides a method for photoelectric energy conversion based on a linear actuator. This method can be executed by at least one of a server, a terminal, or other electronic device capable of executing the method provided by this embodiment of the present application.

[0079] Reference Figure 1 FIG. 1 is a flow chart of a method for converting photoelectric energy based on a linear actuator according to an embodiment of the present invention. In this embodiment, the method for converting photoelectric energy based on a linear actuator includes:

[0080] S1. Receive a photoelectric energy conversion instruction, and start a pre-confirmed photoelectric energy conversion system based on the photoelectric energy conversion instruction, wherein the photoelectric energy conversion system includes: a light detection unit, a positioning unit, a linear drive dual-axis tracking unit, an angle monitoring unit, and a solar photovoltaic unit.

[0081] It is understood 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 used to monitor sunlight intensity in real time. Optionally, a BH1750 light sensor can be used as the light detection unit. Other light sensor models can achieve the same effect and are not described here. The positioning unit is used to determine the spatial position of the sun. Optionally, a u-blox NEO-6M GPS module can be used as the positioning unit and combined with astronomical algorithms to obtain the spatial position of the sun. Other technologies can also be used to achieve this process and are not described here. The linear drive dual-axis tracking unit is a mechanical device used to adjust 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 efficiency of solar energy utilization. The linear drive dual-axis tracking unit contains two sets of linear actuators: a horizontal linear actuator and a vertical linear actuator. The horizontal linear actuator is used to adjust the azimuth angle of the photovoltaic module to ensure 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 to ensure that it is always aligned with the sun in the vertical direction. The angle monitoring unit is used to measure the actual altitude 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 to achieve 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, wherein the photoelectric conversion unit is used to convert solar energy into electrical energy, and the solar power supply unit serves as a storage unit that separately stores the converted electrical energy.

[0082] S2. After the light detection unit confirms that the photoelectric energy conversion system has entered a preset tracking state, the positioning unit is started.

[0083] It should be explained that after the light detection unit confirms that the photoelectric energy conversion system has entered the preset tracking state, the following steps are included:

[0084] When the monitoring time reaches the preset night time 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;

[0085] After confirming that the operation mode of the photovoltaic energy conversion system is the working mode, dividing the preset daytime period into a sub-period sequence based on a preset evaluation frequency, wherein the sub-period sequence includes a plurality of sub-periods, and the sub-periods are composed of a detection period and an execution period;

[0086] When the monitoring time reaches a detection period of a sub-period, the sub-period is taken as an initial sub-period, and within the detection period, a light intensity sequence is acquired based on the light detection unit and a preset light detection frequency, wherein the light intensity sequence includes a plurality of light intensity values, and wherein the working state of the photoelectric energy conversion system includes an inefficient state and a tracking state;

[0087] Based on the initial sub-period, identifying a reference sub-period in the sub-period sequence, wherein the reference sub-period is adjacent to the initial sub-period and lags behind the initial sub-period;

[0088] Obtain the light intensity change rate and light intensity mean based on the light intensity sequence;

[0089] Comparing the light intensity change rate with a preset light intensity change rate threshold and the light intensity mean with a preset light intensity threshold respectively;

[0090] If the rate of change of light intensity is less than or equal to the light intensity change rate threshold and the mean light intensity is less than or equal to the light intensity threshold, the working state of the photoelectric energy conversion system is confirmed as an inefficient state; otherwise, the working state of the photoelectric energy conversion system is confirmed as a tracking state until the monitoring time reaches the execution period of the reference sub-period.

[0091] It is understandable that the preset night time period is a period of time artificially set taking into account 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 operating state entered by the photovoltaic energy conversion system during the night time period. In this mode, the photovoltaic energy conversion system will turn off the linear drive dual-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 entered by the photovoltaic energy conversion system under conditions of sufficient light intensity. In this mode, all units of the photovoltaic energy conversion system are in the on state for photoelectric conversion. The daytime period refers to the time range when the photovoltaic energy conversion system is in working mode, usually from sunrise to sunset.

[0092] It should be understood that the sub-period sequence is a smaller time period divided into the daytime period according to a preset evaluation frequency, and each sub-period includes a detection period and an execution period. The evaluation frequency is the time interval frequency that divides the daytime period into multiple sub-periods. The detection period is the time period in the sub-period used for 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 results of the detection period. The specific operation here refers to the operation of confirming the photovoltaic energy conversion system as being in an inefficient state or a tracking state. The light intensity sequence is a time series containing multiple light intensity values, which is used to describe the changes in light intensity within 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 of the light detection unit obtaining the light intensity value within the detection period of the sub-period.

[0093] For example, assume that the daylight period of a particular 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 one hour, and the daylight period is divided into 10 sub-periods. Taking the initial sub-period of 7:00:00 to 8:00:00 as an example, its preset detection period is 7:00:00 to 7:10:00, and its preset execution period is 7:10:00 to 8:00:00. The reference sub-period is 8:00:00 to 9:00:00, and its corresponding detection period is 8:00:00 to 8:10:00, and its execution period is 8:10:00 to 9:00:00. If the light intensity sequence acquired during the detection period of the initial sub-period (7:00:00 to 7:10:00) meets the tracking state confirmation criteria, then the photovoltaic energy conversion system's operating state is confirmed as tracking during the time period from the execution period start time of the initial sub-period (7:10:00) to the execution period start time of the reference sub-period (8:10:00), where the confirmation process can be switching or not performing an action. Simultaneously, during the detection period of the reference sub-period (8:00:00 to 8:10:00), the light detection unit is again used to acquire the light intensity sequence corresponding to the reference sub-period and determine whether the tracking state confirmation criteria are met. If the tracking state confirmation criteria are not met, then the photovoltaic energy conversion system's operating state is confirmed as inefficient during the time period from the execution period start time of the reference sub-period (8:10:00) to the execution period start time of the next sub-period within the reference sub-period (9:10:00). Among them, the confirmation conditions of the tracking state are: the rate of change of light intensity is greater than the light intensity change rate threshold and the average light intensity is greater than the illumination intensity threshold as two conditions, and any one of the two conditions can be met. The inefficient state is a low-power operating state entered by the photovoltaic energy conversion system when the lighting conditions are relatively weak but inefficient photoelectric conversion can still be performed. In this state, the photovoltaic energy conversion system maintains a better position for photoelectric energy conversion, but the output power is low. The tracking state is an efficient operating state entered by the photovoltaic energy conversion system when the lighting conditions are ideal. By dynamically adjusting the angle of the solar photovoltaic unit, the received light is maximized to achieve efficient photoelectric conversion.

[0094] It can be understood that the illumination intensity mean is the mean of all illumination intensity values ​​in the illumination intensity sequence, and the illumination intensity change rate represents the rate of change of the illumination intensity. For example, the illumination intensity change rate is obtained as follows: Assuming that the illumination intensity sequence is {300lx, 310lx, 315lx, 330lx, 350lx, 400lx}, where the time interval between each two adjacent illumination intensity values ​​is 10 seconds, then the corresponding illumination intensity change rate is (310-300+315-310+330-315+350-330+400-350) / (5 10) The absolute value of d. The illumination change rate threshold is an artificially set change rate threshold, which is used to determine whether the illumination intensity change rate meets the requirements for the photoelectric energy conversion system to enter the tracking state. The illumination threshold is an artificially preset illumination intensity value, which is used to determine whether the current actual illumination conditions meet the requirements for the photoelectric energy conversion system to enter the tracking state. The embodiment of the present invention intelligently switches the working state of the photoelectric energy conversion system by dynamically monitoring the illumination intensity. This adaptive mechanism enables the photoelectric energy conversion system to flexibly switch to the tracking state or the low-efficiency state when the illumination conditions change, ensuring that the photoelectric conversion efficiency is always at the optimal level.

[0095] S3. Acquire the operating 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, wherein the solar spatial position includes the solar altitude angle and the solar azimuth angle.

[0096] It should be understood that the monitoring time is the real-time recording of the photovoltaic energy conversion system's operating time. The solar spatial position refers to the sun's specific position in the sky, typically determined by two parameters: the solar altitude angle and the solar azimuth angle. These describe the sun's vertical and horizontal positions relative to the ground, with the solar photovoltaic unit as the observation point. Optionally, the solar spatial position can be obtained by using a u-blox NEO-6M GPS module as the positioning unit in conjunction with an astronomical algorithm. This is conventional technology and will not be further described here.

[0097] S4. Obtain an adjustment distance set based on the spatial position of the sun, wherein the adjustment distance set includes a horizontal adjustment distance and a vertical adjustment distance. Within a preset tracking deadline, use the adjustment distance set and a linear drive dual-axis tracking unit to adjust the spatial position of the solar photovoltaic unit.

[0098] It should be explained that the acquisition of the adjustment distance set based on the sun's spatial position includes:

[0099] The solar altitude angle in the solar spatial position is taken as the target altitude angle, and the solar azimuth angle in the solar spatial position is taken as the target azimuth angle;

[0100] Acquire an initial altitude angle and an initial azimuth angle based on an angle monitoring unit and a solar photovoltaic unit;

[0101] Acquiring a compensation angle set based on the photoelectric energy conversion system, wherein the compensation angle set includes: a compensation altitude angle and a compensation azimuth angle;

[0102] The vertical adjustment distance is calculated based on the initial altitude angle, the target altitude angle, the compensation altitude angle, and a pre-built vertical distance calculation formula, wherein the vertical distance calculation formula is as follows:

[0103] ;

[0104] in, represents the vertical adjustment distance, represents the target altitude angle, represents the latitude of the geographical location of the solar photovoltaic unit, represents the solar declination angle, represents the hour angle, represents the initial altitude angle, It indicates the change in the initial elevation angle of the solar photovoltaic unit when the linear drive dual-axis tracking unit moves one unit length in the vertical direction. represents the compensation altitude angle;

[0105] The horizontal adjustment distance is calculated based on the initial azimuth, the target azimuth, the compensation azimuth, and a pre-established horizontal distance calculation formula, wherein the horizontal distance calculation formula is as follows:

[0106] ;

[0107] in, represents the horizontal adjustment distance, represents the initial azimuth, It indicates the change in the initial azimuth angle of the solar photovoltaic unit when the linear drive dual-axis tracking unit moves one unit length in the horizontal direction. represents the target azimuth, represents the compensation azimuth;

[0108] Summarize the horizontal adjustment distances and the vertical adjustment distances to obtain an adjustment distance set.

[0109] It is understandable that the initial altitude angle is the current actual altitude angle of the solar photovoltaic unit, which is usually used to describe the current vertical orientation of the solar photovoltaic unit. The target altitude angle is the altitude angle to which the solar photovoltaic unit needs to be adjusted in order to maximize the tracking efficiency of the sun. The initial azimuth angle is the current horizontal orientation angle of the solar photovoltaic unit, which reflects the actual orientation 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 in order to face the sun. 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, using IMU as the angle monitoring unit can obtain the spatial position of the solar photovoltaic unit, which is a prior art and will not be described here.

[0110] Specifically, the step of obtaining a compensation angle set based on a photoelectric energy conversion system includes:

[0111] When the monitoring time reaches a preset first tracking moment, a first solar spatial position is obtained using a positioning unit corresponding to the photovoltaic energy conversion system, wherein the first solar spatial position includes a first solar altitude angle and a first solar azimuth angle;

[0112] Obtaining a first tracking node based on a first tracking time, a first solar altitude angle, and a first solar azimuth angle;

[0113] Obtaining a second tracking time based on the first tracking time and a preset initial tracking time interval;

[0114] When the monitoring time reaches the second tracking time, a second tracking node is obtained using a positioning unit corresponding to the photoelectric energy conversion system, wherein the second tracking node includes the second tracking time, the second solar altitude angle, and the second solar azimuth angle;

[0115] Obtaining a tracking time interval based on the first tracking node and the second tracking node, and obtaining a third tracking time using the tracking time interval and the second tracking time;

[0116] When the monitoring time reaches a third tracking time, a third tracking node is acquired using a positioning unit corresponding to the photovoltaic energy conversion system, wherein the third tracking node includes a third tracking time, a third solar altitude angle, and a third solar azimuth angle, and the third tracking time is the tracking start time;

[0117] A compensation angle set is obtained based on the second tracking node, the third tracking node, and the tracking time interval.

[0118] It is understandable that the first tracking moment and the second tracking moment are both specific moments, corresponding to key time nodes in the initial calibration phase of the solar photovoltaic unit. The first tracking moment is the initial time point when the positioning unit starts to track the position of the sun. The second tracking moment is the next tracking time point that lags 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 when tracking begins, which is used to determine the second tracking moment. At the first tracking moment and the second tracking moment, the photovoltaic energy conversion system performs system calibration by preliminarily acquiring tracking data, providing a basis for subsequent formal tracking.

[0119] It should be understood that the monitoring time is the real-time operating time of the photovoltaic energy conversion system, which is used to determine whether the preset first tracking time, second tracking time, and third tracking time have been reached. For example, assuming a tracking state execution period is from 7:10:00 AM to 8:10:00 AM on a certain day, with 7:10:00 AM as the first tracking time and the initial tracking interval set to 5 minutes, the second tracking time is 7:15:00 AM. When the monitoring time reaches 7:10:00 AM, the positioning unit is used to obtain the spatial position of the sun, resulting in a first solar spatial position. The first solar spatial position is the first solar altitude and first solar azimuth obtained at the first tracking time. The first tracking node is the initial tracking node determined based on the spatial position of the sun when the monitoring time reaches the first tracking time, and is used to record and calculate the initial state of the solar tracking system. When the monitoring time reaches 7:15:00 AM on the same day, the positioning unit is used to obtain the spatial position of the sun, resulting in a second tracking node. The second tracking node is the tracking node determined based on the spatial position of the sun when the monitoring time reaches the second tracking time, and is used to record and calculate the state of the solar tracking system at the second tracking time.

[0120] Furthermore, obtaining the tracking time interval based on the first tracking node and the second tracking node includes:

[0121] Calculating an absolute difference between the first solar altitude angle and the second solar altitude angle to obtain an absolute altitude angle difference, and obtaining an altitude angle change rate based on the absolute altitude angle difference and the initial tracking time interval, wherein the altitude angle change rate is a ratio of the absolute altitude angle difference to the initial tracking time interval;

[0122] Calculating an absolute difference between the first solar azimuth angle and the second solar azimuth angle to obtain an absolute azimuth angle difference, and obtaining an azimuth angle change rate based on the absolute azimuth angle difference and the initial tracking time interval, wherein the azimuth angle change rate is a ratio of the absolute azimuth angle difference to the initial tracking time interval;

[0123] Comparing the elevation angle change rate with a preset elevation angle change rate threshold and the azimuth angle change rate with a preset azimuth angle change rate threshold respectively;

[0124] If the elevation angle change rate is greater than the elevation angle change rate threshold and the azimuth angle change rate is greater than the azimuth angle change rate threshold, the initial tracking time interval is used as the tracking time interval; otherwise, the preset update tracking time interval is used as the tracking time interval.

[0125] It's understandable that the third tracking moment is a specific moment, marking the official start of tracking. Unlike the first and second tracking moments, the third tracking moment is calculated based on the second tracking moment and the dynamically adjusted tracking interval. This moment marks the starting point for the photovoltaic energy conversion system to officially begin tracking the sun's position at the optimized interval after completing initial calibration. The first and second tracking moments are primarily used to obtain initial data, ensuring that the photovoltaic energy conversion system can perform subsequent tracking tasks with greater accuracy and stability after the monitoring time reaches the third tracking moment.

[0126] It should be understood that the tracking interval refers to the time interval used to dynamically adjust the photovoltaic energy conversion system's tracking of the sun's position during the tracking process after the second tracking moment, thereby determining the time interval between two adjacent tracking moments. The elevation angle change rate threshold and the azimuth angle change rate threshold are both manually set rate thresholds, used to determine whether the rate of change of the sun's elevation angle and azimuth angle per unit time, respectively, meets the conditions for adjusting the tracking interval. If the rate of change of the sun's elevation angle is less than the elevation angle change rate threshold, and the rate of change of the sun's azimuth angle is less than the azimuth angle change rate threshold, it indicates that the sun's position is changing slowly, and the initial tracking interval can continue to be used. Otherwise, a smaller updated tracking interval is required to improve tracking accuracy. The third tracking node is a tracking node determined based on the sun's spatial position when the monitoring time reaches the third tracking moment. It is used to record and calculate the state of the solar tracking system at the third tracking moment, and the third tracking moment is the tracking start time. Similarly, the data from the second and third tracking moments can be used to obtain a new tracking interval after the third tracking moment, and the new tracking interval and the third tracking moment can be used to obtain the fourth tracking moment.

[0127] It should be explained that the step of obtaining the compensation angle set based on the second tracking node, the third tracking node, and the tracking time interval includes:

[0128] Obtaining a tracking duration based on the tracking start time and the tracking end time;

[0129] The compensation elevation angle is calculated based on the second tracking node, the third tracking node, the tracking time interval, the tracking duration, and a pre-established compensation angle calculation formula, wherein the compensation angle calculation formula is as follows:

[0130] ;

[0131] in, Indicates the compensation altitude angle, represents the second sun altitude angle, represents the third sun altitude angle, represents the tracking time interval, represents the duration of the tracking;

[0132] Obtaining a compensation azimuth based on the second tracking node, the third tracking node, and the tracking time interval;

[0133] The compensation altitude angles and compensation azimuth angles are summed up to obtain a compensation angle set.

[0134] It should be understood that the tracking start time is the starting time for formal tracking, and the cut-off time is a cut-off time point set based on experience, which is used to ensure that the angle corresponding to the solar photovoltaic unit is adjusted to face the sun as directly as possible within the time range from the tracking start time to the tracking cut-off time. The tracking time interval is the time interval between the tracking start time and the tracking cut-off time, reflecting the total time used by the photovoltaic energy conversion system in the tracking process from obtaining the spatial position of the sun to the completion of the angle adjustment. Completing the adjustment within the preset cut-off time means that the photovoltaic energy conversion system can quantify the error 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 determine the angle deviation caused by the total delay generated by the processes of obtaining the spatial position of the sun, data processing, and angle adjustment.

[0135] It is understood that the compensation angle set is a combination of compensation altitude angles and compensation azimuth angles, used to correct for angular deviations in solar photovoltaic units during sun tracking, thereby improving tracking accuracy. The compensation altitude angle is an angle value calculated to correct for deviations in the solar altitude angle. The compensation azimuth angle is an angle value calculated to correct for deviations in the solar azimuth angle. The compensation altitude angle and compensation azimuth angle are used to adjust the altitude and azimuth angles of the solar photovoltaic unit, respectively, for more precise alignment with the sun, thereby improving tracking accuracy and photovoltaic energy conversion efficiency. The horizontal adjustment distance refers to the actual distance the linear-drive dual-axis tracking unit needs to move horizontally. This horizontal distance is calculated based on the initial azimuth angle, the target azimuth angle, and the compensation azimuth angle. It is used to adjust the azimuth angle of the solar photovoltaic unit so that it is precisely aligned with the horizontal position of the sun. The vertical adjustment distance refers to the actual distance the linear-drive dual-axis tracking unit needs to move vertically. This vertical distance is calculated based on the initial azimuth angle, the target azimuth angle, and the compensation altitude angle. It is used to adjust the altitude angle of the solar photovoltaic unit so that it is precisely aligned with the vertical position of the sun. This embodiment of the present invention improves the tracking accuracy of solar photovoltaic units by dynamically adjusting the tracking interval to reduce errors caused by varying environments and seasonal variations. Simultaneously, it monitors and calculates a compensation angle set in real time to correct for angular deviations in the photovoltaic energy conversion system during the tracking process. Combining the tracking interval and compensation angle set, it accurately calculates the adjustment distance set, ensuring that the solar photovoltaic unit is always aligned with the sun, maximizing photovoltaic energy conversion efficiency.

[0136] S5. After confirming that the adjustment of the solar photovoltaic unit is completed, an adjustment angle set is obtained based on the angle monitoring unit, wherein the adjustment angle set includes an adjustment altitude angle and an adjustment azimuth angle, and a target energy supply system is obtained based on the adjustment angle set and the photovoltaic energy conversion system.

[0137] It should be understood that the elevation angle adjustment is the actual elevation angle of the solar photovoltaic unit measured by the angle monitoring unit after the linear drive dual-axis tracking unit completes the adjustment of the solar photovoltaic unit, which can be used to confirm whether the solar photovoltaic unit has been adjusted to the optimal position in the vertical direction. The azimuth angle adjustment is the actual azimuth angle of the solar photovoltaic unit measured by the angle monitoring unit after the linear drive dual-axis tracking unit completes the adjustment of the solar photovoltaic unit, which can be used to confirm whether the solar photovoltaic unit has been adjusted to the optimal position in the horizontal direction.

[0138] It should be explained that the method of obtaining a target energy supply system based on the adjustment angle set and the photoelectric energy conversion system includes:

[0139] Obtaining a compensated elevation angle based on the target elevation angle and the compensation elevation angle, wherein the compensated elevation angle is the sum of the target elevation angle and the compensation elevation angle;

[0140] Obtaining an absolute altitude angle based on the compensated altitude angle and the adjusted altitude angle, wherein the absolute altitude angle is an absolute difference between the compensated altitude angle and the adjusted altitude angle;

[0141] Obtaining an absolute azimuth based on the target azimuth, the compensation azimuth, and the adjustment azimuth;

[0142] Comparing the absolute altitude angle with a preset altitude angle difference threshold and the absolute azimuth angle with a preset azimuth angle difference threshold respectively;

[0143] If the absolute altitude angle is less than the altitude 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-built solar power supply unit, using the photovoltaic energy conversion power to confirm the power supply mode of the photovoltaic energy conversion system, and obtaining the target energy supply system;

[0144] Otherwise, the solar photovoltaic unit is adjusted using a pre-built adjustment method to obtain the target energy supply system.

[0145] It is understandable that by monitoring the adjusted altitude angle and the adjusted azimuth angle, it is possible to confirm whether the solar photovoltaic unit has been adjusted to the optimal position, thereby determining whether the tracking is successful. The altitude angle difference threshold refers to the maximum allowable deviation range between the adjusted altitude angle and the current solar altitude 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 altitude angle and the current solar altitude angle is less than the altitude 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 efficient conversion of photovoltaic energy is achieved. Otherwise, it indicates that the tracking has failed and needs to be readjusted.

[0146] Furthermore, the method of adjusting the solar photovoltaic unit using the pre-built adjustment method to obtain the target energy supply system includes:

[0147] Obtaining an updated altitude angle based on the adjusted altitude angle and a preset altitude angle adjustment step size;

[0148] Obtaining an updated azimuth angle based on the adjusted azimuth angle and a preset azimuth angle adjustment step size;

[0149] Summarize the updated altitude angle and the updated azimuth angle to obtain an updated angle set, use the updated angle set to adjust the solar photovoltaic unit to obtain an adjusted solar photovoltaic unit, and use the updated angle set corresponding to the adjusted solar photovoltaic unit as the adjusted angle set. Based on the adjusted angle set, the target azimuth angle, the compensated azimuth angle, the target altitude angle and the compensated altitude angle, obtain the absolute azimuth angle and the absolute altitude angle, and return to the steps of respectively comparing the absolute altitude angle with a preset altitude angle difference threshold and the absolute azimuth angle with a preset azimuth angle difference threshold, until the absolute altitude angle is less than the altitude angle difference threshold and the absolute azimuth angle is less than the azimuth angle difference threshold, to obtain the target energy supply system.

[0150] It should be understood that the altitude adjustment step size is used to adjust the fixed angle set for the altitude angle of the solar photovoltaic unit after a certain tracking failure, but before the next tracking moment, to control the amplitude of the altitude adjustment, and ensure that the solar photovoltaic unit gradually approaches the current solar altitude angle in the vertical direction. Similarly, the azimuth adjustment step size is used to adjust the fixed angle set for the azimuth of the solar photovoltaic unit after a certain tracking failure, but before the next tracking moment, to control the amplitude of the azimuth adjustment, and ensure that the solar photovoltaic unit gradually approaches the current solar azimuth in the horizontal direction. Generally speaking, the altitude adjustment step size can be a fixed value, or a value that is dynamically adjusted according to the actual difference between the adjusted altitude angle and the current solar altitude angle. Similarly, the azimuth adjustment step size can be a fixed value, or a value that is dynamically adjusted according to the actual difference between the adjusted azimuth angle and the current solar azimuth angle.

[0151] It is understood that updating the elevation angle refers to adjusting the current elevation angle by adjusting the elevation angle step size to obtain a new elevation angle value. Updating the azimuth angle refers to adjusting the current azimuth angle by adjusting the azimuth angle step size to obtain a new azimuth angle value.

[0152] Specifically, the method of using the amount of electricity converted from photoelectric energy to determine the power supply mode of the photoelectric energy conversion system and obtaining the target energy supply system includes:

[0153] Comparing the photoelectric energy conversion power with a preset tracking power threshold and a preset starting power threshold, wherein the tracking power threshold is greater than the starting power threshold;

[0154] If the photovoltaic energy conversion power is less than the starting power threshold, the photovoltaic energy conversion system is powered by a pre-built traditional power supply unit to obtain a target energy supply system;

[0155] If the photovoltaic energy conversion power is greater than the tracking power threshold, the solar power supply unit is used to power the photovoltaic energy conversion system to obtain a target energy supply system;

[0156] If the photovoltaic energy conversion power is between the starting power threshold and the tracking power threshold, the solar power supply unit is used to power the photovoltaic 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 starting power threshold, the traditional power supply unit is used to power the photovoltaic energy conversion system to obtain the target energy supply system.

[0157] It is understandable that the solar photovoltaic unit includes a solar power supply unit and a photoelectric conversion unit, wherein the function of the photoelectric conversion unit is to convert solar energy into electrical energy, while the solar power supply unit serves as a storage unit for separately storing the converted electrical energy. 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 needs 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 the tracking is confirmed to be successful, it indicates that the current lighting conditions are sufficient and 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 starting 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 efficient tracking function. The tracking power threshold is higher than the starting power threshold. The target energy supply system is a dynamically switching power supply system that can select the most suitable power supply method to power the photovoltaic energy conversion system based on the comparison result of the photovoltaic energy conversion power and the preset threshold, thereby maximizing the use of solar energy to power the photovoltaic energy conversion system.

[0158] For example, when the photovoltaic energy conversion amount is less than the starting energy threshold, the photovoltaic energy conversion system cannot use the photovoltaic energy conversion amount of the solar power supply unit to operate normally, so it switches to the traditional power supply unit to ensure the operation of the photovoltaic energy conversion system. When the photovoltaic energy conversion amount is greater than the tracking energy threshold, the photovoltaic energy conversion system can completely rely on the photovoltaic energy conversion amount generated by the solar power supply unit to operate efficiently and achieve efficient tracking. When the photovoltaic energy conversion amount is between the starting energy threshold and the tracking energy threshold, the photovoltaic energy conversion amount generated by the solar power supply unit is used first to operate and monitor the remaining photovoltaic energy conversion amount. When the photovoltaic energy conversion amount further drops below the starting energy threshold, it switches to the traditional power supply unit to ensure the continuous operation of the photovoltaic energy conversion system. The embodiment of the present invention dynamically adjusts the power supply mode according to the real-time changes in the photovoltaic energy conversion amount, thereby ensuring that the photovoltaic energy conversion system can operate stably under different lighting conditions on the basis of maximizing the use of solar energy.

[0159] The present invention addresses the problems described in the background art. It receives a photovoltaic energy conversion instruction and, based on the instruction, activates a pre-confirmed photovoltaic energy conversion system. The photovoltaic energy conversion system comprises: a light detection unit, a positioning unit, a linear-driven dual-axis tracking unit, an angle monitoring unit, and a solar photovoltaic unit. After the light detection unit confirms that the photovoltaic energy conversion system has entered a preset tracking state, the positioning unit is activated. The present invention intelligently determines the operating state of the photovoltaic energy conversion system by dynamically monitoring light intensity. This adaptive mechanism enables the photovoltaic energy conversion system to flexibly switch between a tracking state and a low-efficiency state when lighting conditions change, ensuring that photovoltaic conversion efficiency remains at an optimal level. The present invention obtains the operating time of the photovoltaic energy conversion system in real time to obtain a monitoring time. When the monitoring time reaches a preset tracking start time, the activated positioning unit is used to obtain the spatial position of the sun, which includes the solar altitude angle and the solar azimuth angle. Based on the solar spatial position, an adjustment distance set is obtained, which includes a horizontal adjustment distance and a vertical adjustment distance. Within a preset tracking end time, the adjustment distance set and the linear-driven dual-axis tracking unit are used to adjust the spatial position of the solar photovoltaic unit. It can be seen that the present invention reduces errors caused by different environments 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 by the photovoltaic energy conversion system in the tracking process from obtaining the spatial position of the sun to completing the angle adjustment. 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 and maximize the photovoltaic energy conversion efficiency. After the present invention confirms that the adjustment of the solar photovoltaic unit is completed, the adjustment angle set is obtained based on the angle monitoring unit, wherein the adjustment angle set includes adjusting the altitude angle and adjusting the azimuth angle, and the target energy supply system is obtained based on the adjustment angle set and the photovoltaic energy conversion system. It can be seen that the present invention dynamically adjusts the power supply mode according to the real-time changes in the amount of photovoltaic energy converted, and ensures that the photovoltaic energy conversion system can operate stably under different lighting conditions on the basis of maximizing the use of solar energy. Therefore, the present invention can improve the efficiency and flexibility of photovoltaic energy conversion.

[0160] like Figure 2 , which is a functional module diagram of a photoelectric energy conversion system based on a linear actuator provided by an embodiment of the present invention.

[0161] The linear actuator-based photovoltaic energy conversion system 100 described in the present invention can be installed in an electronic device. Depending on the functionality to be implemented, the linear actuator-based photovoltaic energy conversion system 100 may include a tracking status confirmation module 101, a solar spatial position acquisition module 102, a photovoltaic unit position adjustment module 103, and a tracking result confirmation module 104. A module, also referred to as a unit, is a series of computer program segments that can be executed by an electronic device's processor and perform a fixed function. These modules are stored in the electronic device's memory.

[0162] The tracking state confirmation module 101 is used to receive a photoelectric energy conversion instruction and start a pre-confirmed photoelectric energy conversion system based on the photoelectric energy conversion instruction, wherein the photoelectric energy conversion system includes: a light detection unit, a positioning unit, a linear drive two-axis tracking unit, an angle monitoring unit, and a solar photovoltaic unit;

[0163] After the light detection unit confirms that the photoelectric energy conversion system has entered a preset tracking state, the positioning unit is started;

[0164] The solar spatial position acquisition module 102 is used to obtain the operating 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, the solar spatial position is obtained by using the activated positioning unit, wherein the solar spatial position includes the solar altitude angle and the solar azimuth angle.

[0165] The photovoltaic unit position adjustment module 103 is configured to obtain an adjustment distance set based on the spatial position of the sun, wherein the adjustment distance set includes a horizontal adjustment distance and a vertical adjustment distance, and to adjust the spatial position of the solar photovoltaic unit using the adjustment distance set and a linear drive dual-axis tracking unit within a preset tracking cutoff time;

[0166] The tracking result confirmation module 104 is used to confirm that the adjustment of the solar photovoltaic unit is completed, obtain an adjustment angle set based on the angle monitoring unit, wherein the adjustment angle set includes an adjustment altitude angle and an adjustment azimuth angle, and obtain a target energy supply system based on the adjustment angle set and the photovoltaic energy conversion system.

Figure 1 The photoelectric energy conversion method based on the linear actuator described in the invention has the same technical means and can produce the same technical effects, so it will not be repeated here.

[0177] The photoelectric energy conversion method program based on a linear actuator stored in the memory 11 of the electronic device 1 is a combination of multiple instructions. When running in the processor 10, it can achieve the following:

[0178] receiving a photoelectric energy conversion instruction, and starting a pre-confirmed photoelectric energy conversion system based on the photoelectric energy conversion instruction, wherein the photoelectric energy conversion system includes: a light detection unit, a positioning unit, a linear drive two-axis tracking unit, an angle monitoring unit, and a solar photovoltaic unit;

[0183] Specifically, the specific implementation method of the processor 10 for the above instructions can refer to Figures 1 to 3 The description of the relevant steps in the corresponding embodiments will not be repeated here.

[0184] Furthermore, if the modules / units integrated into the electronic device 1 are implemented as software functional units and sold or used as independent products, they may be stored in a computer-readable storage medium.
