Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent light-tracking technology, and in particular to an intelligent light-tracking method, system, and its application in artificial flowers. Background Technology
[0002] Solar-powered artificial flowers are an innovative product combining photovoltaic power generation technology and decorative art. They can simulate the visual effect of real flowers and provide lighting at night by generating and storing solar energy. Currently, most artificial flowers use photovoltaic panels with fixed-angle light sources, which cannot dynamically adjust the direction of sunlight reception according to changes in sunlight, thus failing to maximize the absorption of solar radiation energy. Efficiency drops significantly, especially during cloudy or rainy weather or seasonal changes. The sun-tracking function design of the photovoltaic panel components in solar-powered artificial flowers is crucial to their power generation efficiency and is generally a key component designed and optimized.
[0003] For example, Chinese patent application number 2023219897282 discloses a light-tracking adjustment component for photovoltaic power generation panels, including a housing, a fixing block installed in the inner cavity of the housing, a fixing groove opened on the surface of the fixing block, a control board installed in the inner cavity of the fixing groove, a motor installed in the inner cavity of the housing, a frame connected to the output end of the motor, a fixing plate installed in the inner cavity of the frame, and a photosensor installed on the surface of the fixing plate. The above invention only optimizes the angle of the protective box and does not feed back the dynamic light-tracking data to the lighting control module, thus failing to achieve coordinated adjustment of lighting intensity and natural light.
[0004] For example, Chinese Patent Application No. 2023106997465 discloses a solar tracking method and a solar-powered lighting device. The solar-powered lighting device has multiple solar panels, and the solar tracking method includes the following steps: S10, periodically acquiring the light intensity acquired by the multiple solar panels from different directions; S20, when the total light intensity acquired by the multiple solar panels from different directions reaches a preset light intensity value, setting the center point of the solar panel with the highest light intensity among the multiple solar panels as the target center point; S30, controlling the center points of the multiple solar panels to rotate to the target center point, and returning to the execution of step S10. The above invention aims to improve the conversion efficiency of solar panels for light, but the above invention cannot effectively adjust for light source interference.
[0005] Similar to the existing technologies described above, when tracking sunlight to improve power generation efficiency, especially for photovoltaic devices installed at low locations, the devices are also subject to interference from various light sources when receiving sunlight. For example, highly reflective surfaces such as water surfaces, snow, or glass curtain walls may generate strong reflected light, as well as interference from various light sources such as high-intensity artificial light sources and cloud-scattered light. Since photovoltaic power generation capacity depends on the matching degree between photon energy distribution and the bandgap of semiconductor materials, the power generation efficiency of interfering light sources is much lower than that of sunlight. When the intelligent tracking system tracks sunlight, the interfering light sources can easily cause the device to misjudge the light source information, resulting in the intelligent tracking system frequently starting up or tracking the movement of interfering light sources, thus affecting the power generation efficiency.
[0006] Furthermore, in real-world scenarios, the shape and direction of the shadows cast by buildings near the device constantly change with the movement of the sun. Since the device is located in a low-lying area, it is easily blocked by shadows, thus affecting the photovoltaic power generation efficiency. Moreover, as moving objects approach or move away from their shadows, the tracking ability of the intelligent tracking system is also affected, causing the intelligent tracking system to repeatedly start and stop, thus impacting power generation efficiency.
[0007] Meanwhile, when encountering consecutive cloudy days, the solar tracking system cannot capture the sun's movement trajectory, causing the photovoltaic device to remain at a certain angle. As the sun rises and sets, when sunlight shines on the back of the photovoltaic device, the device cannot capture the sunlight in time.
[0008] Therefore, it is necessary to invent a method, system, and simulated flower that uses light-tracking technology to solve the above problems. Summary of the Invention
[0009] The purpose of this invention is to provide a method, system, and simulated flower that uses the same for intelligent light tracking, in order to solve the problems mentioned in the background art.

If it is within the allowable error range of the predicted rate of change of illumination, then execute S350. If it is not within the allowable error range of the predicted rate of change of illumination, then execute S330.
[0017] S330: Identify the shadow area within the real-time acquired photovoltaic panel image and calculate the image shadow change rate. If the image shadow change rate is less than a first preset value, proceed to S340. If the image shadow change rate is greater than the first preset value but less than a second preset value, correct the first surrounding environment total shadow prediction model based on wind speed, plant shape, and plant height. Predict whether there is an unobstructed area in the target adjustment height space using the corrected first surrounding environment total shadow prediction model. If there is, proceed to S360; if not, proceed to S350. If the image shadow change rate is greater than the second preset value, proceed to S370.
[0018] S340. Based on the second surrounding environment total shadow prediction model, predict whether there is an unobstructed area in the target's height adjustment space. If there is, execute S360; if not, execute S350.

[0023] Preferably, the adjustment module includes a support rod, a lighting component at the top of the support rod, a support component at the bottom of the support rod, a hollow internal structure with a telescopic component, and multiple connecting slots arranged in a ring array on the support rod. The telescopic component is specifically a pneumatic telescopic structure filled with gas, and a vent valve is provided at the top of the telescopic component.

[0030] The technical effects and advantages of this invention are as follows:
[0031] 1. This invention collects and analyzes the light source information of the environment in which the simulated flower is located, enabling the photovoltaic panel to follow the sun's movement trajectory for light-tracking operations, thereby avoiding the influence of interfering light sources on the device.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0043] To overcome the problem of low power generation efficiency caused by factors such as light interference when photovoltaic devices are installed at low locations.
[0044] In a first embodiment of the present invention, a light-tracking intelligent system is provided. The system includes a wind speed detection module, an image acquisition module, a light source detection module, an integrated learning module, a control module, and an execution module. The wind speed detection module is used to detect wind speed; the image acquisition module is used to acquire images of photovoltaic panels and surrounding buildings and plants; the light source detection module is used to collect light source characteristics and can determine the solar light source by analyzing the light source; the learning module is based on a data correction model; the control module is used to process light source information and shading information; and the execution module is used to perform operations according to the instructions issued by the control module.
[0045] To prevent issues such as the system misinterpreting light sources when exposed to sunlight, especially when receiving interference from different light sources or when the intelligent tracking system is tracking the sun, and the changing shape and direction of shadows cast by nearby buildings due to the sun's movement, causing the intelligent tracking system to repeatedly start and stop, thus affecting power generation efficiency, and the inability of the tracking system to capture the sun's trajectory during consecutive cloudy days, resulting in the photovoltaic device remaining at a certain angle, and the system failing to capture sunlight on the back of the photovoltaic device as it rises and sets, the problem of the system not being able to capture sunlight in time.
[0046] In another embodiment of the invention, such as Figures 2 to 8 As shown, the intelligent light-tracking system also includes an adjustment module, which includes a support rod 1. The top of the support rod 1 is equipped with a lighting component 2. The intelligent light-tracking system can be applied to streetlights and energy-saving lighting devices, and the lighting component 2 can be modified to set different shapes, such as various flowers, according to usage requirements.
[0047] In this embodiment, the support rod 1 has a support component 3 at its bottom, the support rod 1 has a hollow structure inside and is provided with a telescopic component 4, and the support rod 1 has multiple connecting slots 6 arranged in a ring array. The telescopic component 4 is specifically a pneumatic telescopic structure, which is filled with gas, and the top of the telescopic component 4 is provided with a vent valve 5.
[0048] It should be noted that the telescopic component 4 can be a pneumatic telescopic structure similar to a telescopic cylinder, with its fixed end fixedly connected to the bottom of the support rod 1. The length of the telescopic component 4 can be changed by adding or releasing air into it.
[0049] In this embodiment, a sliding sleeve 7 is fitted on the outer side of the support rod 1. A limiting hole 8 communicating with the connecting groove 6 is provided on the sliding sleeve 7. A fixing member 9 is provided in each limiting hole 8. The fixing member 9 passes through the limiting hole 8 and is fixedly connected to the moving end of the telescopic member 4. The sliding sleeve 7 and the telescopic member 4 are connected by the fixing member 9. When air is added or released into the telescopic member 4, the telescopic member 4 can drive the sliding sleeve 7 to slide up and down on the support rod 1 through the fixing member 9, providing a basis for the photovoltaic device to change its height to avoid shadows.
[0050] In this embodiment, the sliding sleeve 7 has multiple mounting slots arranged in a ring array. Each mounting slot is slidably connected to a limiting plate 10. Each limiting plate 10 is provided with an inflation mechanism 11 at its lower part. The air outlet of the inflation mechanism 11 is connected to the fixed end of the telescopic member 4 to inflate the telescopic member 4 and make the telescopic member 4 extend.
[0051] It should be noted that the inflation mechanism 11 can be a type of manual air pump, which drives the piston inside the cylinder to move up and down by pressing, sending the gas inside the cylinder into the telescopic member 4. The air outlet end of the air pipe is equipped with a one-way valve to prevent the gas inside the telescopic member 4 from flowing back after the pressing pressure is released. Each mounting slot is equipped with a return spring above the limiting plate 10. When the limiting plate 10 is subjected to external force, the limiting plate 10 can overcome the elastic force of the return spring and slide in the mounting slot, pressing the inflation mechanism 11. When the external force is removed, the limiting plate 10 can drive the inflation mechanism 11 to return to its initial position under the elastic force of the return spring. By continuously applying external force, the telescopic member 4 can be continuously replenished with air to increase its length.
[0052] In this embodiment, each fixing member 9 is fixedly connected to two limiting rings 12, and a connecting rod 13 is provided between two adjacent fixing members 9. The two ends of each connecting rod 13 extend into the two limiting rings 12 and are rotatably connected to the limiting rings 12. The limiting rings 12 are provided with a rotating mechanism, which can drive the connecting rods 13 to rotate through electrical control. Each connecting rod 13 is provided with a rotating plate 14 along the vertical direction of the support rod 1. When the connecting rod 13 rotates counterclockwise, it can contact the limiting plate 10 and drive the limiting plate 10 to move downward to compress the inflation mechanism 11 to perform air replenishment operation in the telescopic member 4.
[0053] It should be noted that each limiting plate 10 is provided with a sliding wheel at the end near the connecting rod 13 to prevent the limiting plate 10 from jamming with the connecting rod 13, and each protective box 16 and mounting plate 18 is provided with clearance angles around its perimeter to avoid interference during movement.
[0054] In this embodiment, each link 13 is fixedly connected to a mounting plate 18 on the side away from the support rod 1. A rotating motor 15 is fixedly connected to the middle of the mounting plate 18. A protective box 16 is fixedly connected to the output shaft of the rotating motor 15. Multiple photovoltaic panels 17 are arrayed on the protective box 16. Multiple light source detection modules are provided on the protective box 16. The light source detection module, the integrated learning module, and the control module are all located inside the protective box 16.
[0055] In use, the support assembly 3 sets the support rod 1 in the desired area, and the multiple protective boxes 16 change from a retracted state to an unfolded state. In this state, the photovoltaic panels 17 on the multiple protective boxes 16 all face the sun. At this time, the light source detection module installed in the protective box 16 collects the light source illuminating the area of the photovoltaic panel 17, and analyzes and filters this part of the light source to identify sunlight. For example, a UV sensor is installed in the light source detection module to detect ultraviolet rays, thereby determining the source of sunlight (because in the usage environment, other light sources generally do not emit ultraviolet rays). Of course, other existing technologies can also be used to determine the source of sunlight. The control module controls the rotation mechanism set on the limit ring 12 to drive the connecting rod 13 and the protective box 16 to rotate around the axis of the connecting rod 13. At the same time, the rotation motor 15 drives the protective box 16 to rotate around the output shaft of the rotation motor 15, thereby realizing the sunlight tracking operation, so that each photovoltaic panel 17 on the protective box 16 can receive sunlight.
[0056] When collecting solar energy, since the sun is always in motion, the light source is detected in real time by the light source detection module, and the rotation angle of the rotating mechanism and the rotating motor 15 is adjusted in real time by the control module so that the photovoltaic panel 17 can always receive sunlight in the presence of sunlight.
[0057] This invention has three working modes: a tracking mode based on regular illumination correction, a tracking mode based on regular illumination, and a tracking mode based on regular illumination.
[0058] Height adjustment mode and automatic protection mode.
[0059] During the solar energy harvesting process, the real-time rate of change of light intensity is calculated based on the characteristics of the light source collected in real time. Then, the real-time rate of change of light intensity is compared with the predicted rate of change of light intensity predicted by the cloudless solar light intensity change rate prediction model.
[0060] If the change in light intensity is within the allowable error range of the predicted rate of change in light intensity, indicating that the change in light intensity is caused by the regular movement of the sun, then the "light tracking mode based on regular light intensity correction" will be executed.
[0061] If the shadow area is outside the allowable error range of the predicted rate of change of illumination, the shadow area in the real-time acquired photovoltaic panel image is identified, and the rate of change of the image shadow is calculated.
[0062] If the rate of change of the image shadow is less than the first preset value, it indicates that the change in light intensity is caused by the shadow changes of buildings and trees caused by the movement of the sun, which block the photovoltaic panel. Then, based on the second total shadow prediction model of the surrounding environment, it is predicted whether there is an unblocked area in the target height adjustment space. If there is, the "height adjustment mode" is executed; if not, the "tracking mode based on regular light correction" is executed.
[0063] If the rate of change of the image shadow is greater than the first preset value and less than the second preset value, it indicates that the change in light intensity is mainly caused by the swaying of trees due to wind speed, which causes the shadows of the trees to block the photovoltaic panels. Then, the first total shadow prediction model of the surrounding environment is corrected according to the wind speed, plant shape, and plant height. The corrected first total shadow prediction model of the surrounding environment is used to predict whether there is an unblocked area in the target height adjustment space. If there is, the "height adjustment mode" is executed; if not, the "tracking light mode based on regular light correction" is executed.
[0064] If the rate of change of the image shadow is greater than the second preset value, it indicates that the speed of change is fast, and "Enable Automatic Protection Mode" will be executed.
[0065] It should be noted that the first preset value is the rate of change of shadows formed by the movement of sunlight and trees according to the sun's pattern when the building and trees are in a windless condition; the second preset value is the rate of change of shadows formed by the rapid blocking of photovoltaic panels by the shadows of trees caused by the swaying of trees due to wind speed when the building and trees are in a windy condition. The first total shadow prediction model of the surrounding environment is a shadow prediction model formed according to the sun's pattern when there is wind. The second total shadow prediction model of the surrounding environment is a shadow prediction model formed according to the sun's pattern when there is no wind.
[0066] The specific operation of the height adjustment mode is as follows: By controlling multiple connecting rods 13 to rotate counterclockwise, the rotating plate 14 set on the connecting rod 13 rotates towards the limiting plate 10 and squeezes the limiting plate 10, thereby squeezing the inflation mechanism 11 by the limiting plate 10, forcing gas into the telescopic member 4, causing the telescopic member 4 to extend, driving the sliding sleeve 7 to move upward, and controlling the connecting rod 13 to rotate clockwise to return to the initial position. At the same time, the light source detection module detects the protective box 16 again. If the protective box 16 still has an obstruction area and cannot be avoided by rotating the motor 15, the above operation is repeated until the obstruction area is avoided.
[0067] When the weather conditions in the area where the solar tracking system is located are continuous cloudy days or other weather conditions that prevent direct contact with sunlight, the control components control each protective box 16 to adjust the illumination angle according to the solar trajectory provided by the prediction model. This avoids the problem that when encountering continuous cloudy days, the solar tracking system cannot capture the solar movement trajectory, causing the photovoltaic device to remain at a certain angle. As the sun rises and sets, when sunlight shines on the back of the photovoltaic device, the solar tracking system cannot capture the sunlight in time.
[0068] To prevent damage to the photovoltaic panel 17 during strong winds or heavy rain, in another embodiment of the present invention, a rain detection module can be installed on the outside of the protective box 16 to detect environmental changes in the scene where the device is located in real time through the wind speed detection module and the rain detection module.
[0069] When heavy rain or strong winds are detected in the scene where the device is located, the automatic protection mode is activated. In this mode, multiple rotating motors 15 are controlled to rotate the protective box 16, so that the end of the protective box 16 with the photovoltaic panel 17 is turned from top to bottom. Then, the connecting rod 13 is controlled to rotate multiple protective boxes 16 clockwise, so that the protective box 16 changes from a horizontal state to a vertical state. In this state, the protective box 16 with the photovoltaic panel 17 is located on the side closer to the support rod 1. By combining multiple protective boxes 16 into a cube-like structure, the multiple photovoltaic panels 17 inside the cube are effectively protected, avoiding damage to the photovoltaic panels 17 in severe weather. When the wind speed detection module and the rain detection module detect that the rain or wind has stopped, the multiple protective boxes 16 are controlled to rotate according to the solar motion trajectory predicted by the prediction model, so that the photovoltaic panel 17 moves to the optimal irradiation angle to continue irradiation.
[0070] like Figure 1 In another embodiment of the present invention, a light-tracking intelligent method is also provided, which utilizes the above-mentioned system to improve the problem of low power generation efficiency of low-altitude photovoltaic devices, which makes it difficult to meet the requirements of use.
[0071] The method includes the following steps:
[0072] S100: Capture multiple light sources in the scene and perform feature acquisition and processing to determine the sunlight source;
[0073] S200 captures the trajectory of sunlight and images of surrounding objects, as well as wind speed, and records the data to construct a first total shadow prediction model for the surrounding environment, a second total shadow prediction model for the surrounding environment, and a prediction model for the rate of change of sunlight in cloudless conditions.
[0074] S300, based on a cloudless solar illumination change rate prediction model, a first ambient total shadow prediction model, a second ambient total shadow prediction model, and real-time acquired light source characteristics to correct the light-tracing path.
[0075] Step S300 includes the following steps:
[0076] S310. Calculate and obtain the real-time illumination change rate based on the real-time collected light source characteristics;
[0077] S320. Compare the real-time rate of change of illumination with the predicted rate of change of illumination predicted by the cloudless solar illumination rate of change prediction model. If it is within the allowable error range of the predicted rate of change of illumination, it indicates that the change in illumination intensity is caused by the regular movement of the sun. Then execute S350. If it is not within the allowable error range of the predicted rate of change of illumination, execute S330.
[0078] S330: Identify the shadow area within the real-time acquired photovoltaic panel image and calculate the image shadow change rate. If the image shadow change rate is less than a first preset value, it indicates that the change in light intensity is caused by the shadow changes of buildings and trees due to the movement of the sun, which block the photovoltaic panel. Then proceed to S340. If the image shadow change rate is greater than the first preset value and less than the second preset value, it indicates that the change in light intensity is mainly caused by the swaying of trees due to wind speed, which causes the shadows of trees to block the photovoltaic panel. Then, based on wind speed, plant shape, and plant height, correct the first surrounding environment total shadow prediction model. Predict whether there is an unblocked area in the target adjustment height space using the corrected first surrounding environment total shadow prediction model. If there is, proceed to S360; if not, proceed to S350. If the image shadow change rate is greater than the second preset value, it indicates that the speed change is fast. Then proceed to S370.
[0079] S340. Based on the second surrounding environment total shadow prediction model, predict whether there is an unobstructed area in the target's height adjustment space. If there is, execute S360; if not, execute S350.
