Description of the Invention: [Technical Field] The present invention relates to a solar tracking device, and more particularly to a solar tracking system that utilizes the image-matching method to track the Taizhizhitai tracking device and utilizes the tracking and cracking. [Prior Art] It is conventional to use a light sensor to achieve a device for tracking the sun. Signals from one or more light sensors drive the power system to adjust the sun tracking device to the position facing the sun. As shown in FIG. 1 and FIG. 2, the conventional solar tracker 1 includes an opaque housing 12, and a housing concentrator 14 is mounted on the housing 12, and a measurement area 16 is disposed at the bottom end of the housing 12. The concentrating tube 14 is vertically projected to the detecting area 16. Four light sensing devices 18 are mounted around the detection zone 16. When the sun is located directly above the concentrating tube 14, the solar ray ai passes through the concentrating tube 14 and is projected to the B area, at which time the sun tracker i does not move. After a period of time, the sun is shifted to the right to an angle ¥ to the right of the concentrating tube 14, and the illuminating light passes through the concentrating tube 14 and is projected onto the light sensor 18 around the b region, and the light sensor 18 senses the light. After that, the driving power system (not shown) fine-tunes the position of the sun chaser, so that the light from the sun returns to the B area. The system is constantly repetitive, allowing the tracker to face the sun forever, to track the sun. However, by using the light sensor 18 to sense the sunlight to adjust the sun tracker 1, it is necessary to adjust the position of the sun tracker 200944731 after the light sensor 18 senses, so the accuracy of the sun tracker i actually aligns with the sun. , will be adjusted (four) indeed (the error is the smallest (four) sunny (four) ^ gradually reduced until the lower - engraved light perception ϋ I8 again sense (the error is the biggest), once again adjust the position of the sun tracker 1 'accuracy will change again Accurate, as shown in Figure 3. "When the right is used in solar power generation, the efficiency of solar cell power generation will be higher with the accuracy of the solar cell facing the sun, the more power generation, and the lower the accuracy, the lower the power generation. The amount is also less. Therefore, as shown in Fig. 3, when the conventional solar tracker 1 is applied to solar power generation, it is shown in Fig. 4. At time t=〇, the accuracy error between the solar tracker 1 and the sun is the smallest. Therefore, the solar power generation is the largest (Emax), and as time passes, the accuracy error reaches the maximum when t=ti, and the power generation is the smallest (Emin). At this time, the light sensor 18 also detects the sunlight, so the adjustment Sun tracker丨The sun tracker is again aligned with the sun', and the power generation reaches its maximum. As shown in Figure 4, during the period of t=〇, the solar power generation is changed from maximum to minimum. Ming Q appears to know that the actual power generation The efficiency is not high. Therefore, the solar tracker 1 activated in this way is not effective for solar power generation. Moreover, when the sun is offset toward both sides of the concentrating tube 14, and the projected light exceeds the B area, When going to the A area, the sun tracker j will have no light sensor 18 in the a area, so it is no longer possible to adjust the sun. This often occurs when the sky appears in the clouds, covering the sun for a while, and this time light The sensor 18 cannot sense the sun to project light, and after the cloud layer is dispersed, the tracker 1 easily loses the sun position and can no longer track the sun. 200944731 In addition, the 'light sensor 18 senses the sun' and activates the sun tracker 1 to adjust its The position is facing the sun, because the area of the B area is still large, so the sun tracker 1 is not easy to face the sun, which also causes the solar tracker 1 to face the problem of limited accuracy of the sun. Male tracker accuracy for the actual lifting of the sun, clouds, and after dispersed, can continue to track the sun; and using this to tracker

The description of the present invention and the description of the following embodiments are used to demonstrate and explain the present invention. The present invention is not limited to the scope of the present invention. [Embodiment] In order to further understand the objects, structures, features, and functions of the present invention, the following detailed description will be given with reference to the embodiments. The schematic diagram of the first embodiment of the solar power generation system 2 of the present invention comprises a support column 22, a solar panel 24, a solar tracking device 26 and a power device 28. Pillars for supporting the entire system. The solar panel 24, which absorbs sunlight and converts light energy into electrical energy, has a direct light plane 24a, which is similar to the conventional solar panel. 22, it can be rotated in various directions on the support column 22. Please refer to Fig. 6, which is a block diagram of the sun tracking device of the present invention. The solar tracking device 26 is disposed on the support column 22 and disposed in the same direction as the light plane 24a of the solar panel 24, and is provided with an optical component 26 and an image capturing unit 262 and an image processing unit 2 200944731 A memory unit 264. The optical element 26 is a focusing lens for focusing sunlight onto the image capturing unit 261. The optical element 261 may be selectively provided and may be implemented as a lens or a wide-angle lens or the like. When the lens is implemented as a lens, the sun at a specific position can be imaged by the image capturing unit 262. When implemented as a wide-angle lens, the sun can appear in the image capturing unit 262 anywhere in the sky. In addition, lenses and wide-angle lenses can be used simultaneously. The image picking unit 262 is a semiconductor capable of recording light changes, and has a photosensitive element thereon, which transmits the light from the surface of the photosensitive element through the photoelectric effect, thereby being converted into an electronic signal and stored on the detector until it is read. Out: When the image capturing unit 262 receives the light, it converts the light bl into a charge. The stronger the light, the more the charge, and the charge becomes the basis for judging the intensity of the light. Therefore, the image capturing unit 262 can optically perform image capturing on an object, and can be implemented as a Charge Coupled Device (CCD) or a Complementary Metal-Oxide Semiconductor (Complementary Metal-Oxide Semiconductor). CMOS) and so on. In an embodiment of the invention, the & images are continuously captured using cCD. The image processing unit 263 is disposed at the output end of the image capturing unit 262 to recombine the charge signal of the image capturing unit 262 via a computer to form an image. It is also possible to calculate data by software calculation. In the embodiment of the present invention, the solar image captured by the image capturing unit 262 is presented at the image processing unit 263, and the solar image obtained by the software operation is used for adjusting the system and tracking the sun. use. The memory unit 264 is configured to store various materials and provide the stored data to the image processing unit 263. In the embodiment of the present invention, the memory unit 264 stores the data of the data and the history track of the solar history, which are compared by the image processing unit 263, and also stores the originally stored data in the image processing unit 263. ❹ A power unit 28 is disposed on the support column 22, for example, a motor (not shown) provides power to rotate the solar panel 24 on the branch column 22, so that the solar panel 24 is forwarded to the sun. It is similar to the conventional solar power generation system. The operation of the solar power generation system 2 of the present invention controls the solar panel 24 to accurately power the solar power by means of image comparison. First, the optical element 261, such as a focus lens, is used to focus the solar image P by the optical element 261 so that its focus falls on the image pickup unit 262. The image capturing unit 262 optically performs the sun image to capture the sun image at a specific time interval. The sun image captured here is called the second sun image, which is the actual sun image. The specific time interval can be set to 1 second, 2 seconds or 30 seconds... and so on. Therefore, the image capture order, 26 ^ can capture a lot of second sun images over a period of time. For example, if the specific time interval is set to! In seconds, the image capturing unit 262 can capture 60 second solar images in one minute. -12- 200944731 § Recalling unit 264, a first sun image is pre-stored, and the first sun image is a preset sun image having a first sun center. Please refer to FIG. 7' for a schematic view of the image processing unit 263 of the solar tracking device 26. The first solar image 2642 is in the image processing unit 263, and the position of the image 2642 in the pupil plane 2632 is fixed. When the image capturing unit 262 transmits the signal of the captured second solar image 2622 to the image processing unit 263, then at a certain position on the screen 2632, a second solar image 2622 of a sun shape is formed, and Has a second sun center ❹ 2624. The image processing unit 263 compares the first solar center 2644 of the first solar image 2642 memorized by the memory unit 264 with the second solar center 2624 of the second solar image 2622, because the second solar center 2624 is on the picture 2632. The position is different from the first sun center 2644, so a difference data can be obtained. As shown in Fig. 7, this difference data is composed of a small error χ (Δχ) and a small error y (Ay). This means that the direction of the solar panel 24 toward the sky at this moment has an error distance of Δχ and Ay from the actual sun position in the sky. At this time, the image processing unit 263 stores the difference information in the memory unit 264 to provide a defect for pre-actuating the power unit 28. At the same time, according to the difference data, the power device 28 is immediately actuated, and the solar panel 24' is adjusted. Thus, the first solar center 2624 of the second solar image 2622 taken in the next second is matched with the first solar image 2642. At the same time, the solar panel 24 of the solar power generation system 2 is precisely aligned with the sun. When the sky has a cloud covering part of the sun, the image processing unit 263 can also calculate the second sun center 2624 of the second sun image 2622 for comparison. It is worth noting that the first solar image 2642 is pre-set, 200944731 is used as a reference for the second solar image 2622 alignment, so the position of the image in the picture 2632 is fixed, and the image is captured. If the second solar center 2624 of the second solar image 2622 matches the first solar center 2644 of the first solar image 2642, it also represents that the solar panel 24 is facing the sun. At each specific time interval, the image capturing unit 262 captures a second solar image 2622' and presents it at the image processing unit 263. Therefore, each time a second solar image 2622' is generated, the image processing unit 263 compares it with the first solar image 2642 to obtain a difference data, and then activates the power device 28 to adjust the solar panel 24 to the sun. Therefore, the solar panel 24 can always be positive to the sun. The comparison between the first solar image 2642 and the second solar image 2622 is compared with the two solar centers 2624 and 2644, and the difference information of the displacement of the sun center position is obtained to adjust the second solar center 2624 of the second solar image 2622. Matches the first sun center 2644. Therefore, the solar panel 24 can accurately advance to the sun, effectively improving accuracy. As shown in FIG. 8 and FIG. 9 , because the image capturing unit of the solar power generation system of the present invention captures the specific interval of the second solar image, it can be set to be very short (eg, -second) and the Xiangyang solar circle is read. The accuracy of the solar panel 24 (see item 5) riding the sun is very accurate. As shown, the accuracy error is quite low. In this way, the power generation of the solar energy system 2 can also be made to a relatively high degree, and the power generation amount can be effectively increased. ▲ In addition, in another embodiment of the present invention, the memory of the sun can be stored and recorded. The past movement of the sun has been recorded. 'This § recorded data can be included in Yu ρ,. 斗,., 贝丁叶J匕& cut one day, last year, or four years ago (because every-14-200944731 four years) Run once a year, so the sun will travel for four years and one cycle). The memory unit 264 can provide the image processing unit 263 with the information, = first actuating the power unit 28. For example, the memory unit 264 can provide the moving track data of the sun four years ago to the image processing unit 263, and after the image processing unit 263 is operated by the software, the power device 28 can use the data for the next second of the sun movement. Before (assuming a specific time interval is set to one second), the position of the solar panel 24 to the next second of the sun is adjusted in advance to reach the realm of "synchronization with the sun". And using this recorded data, when the solar energy is generated In use, even if the cloud layer covers the sun for a period of time, the solar power generation system 2 can also provide the image processing unit 263 to actuate the power device 28 by using the moving track data of the sun stored in the memory unit 264, such that the solar power generation system 2 After the sun is covered by the cloud for a period of time, the sun can be accurately found and accurately aligned when the sun reappears. In still another embodiment of the solar power generation system 2 of the present invention, the optical element 261 can also use a wide-angle lens. The wide-angle lens is a lens that is about 180 degrees. It can focus on any image of the sun in the sky. In this way, the solar power generation system 2 can capture the second solar image regardless of whether the sun is in any part of the sky, and the solar image can be captured without being able to find the sun. In addition, the lens can be used simultaneously with the wide-angle lens. Using the wide-angle lens to focus the sun image in any part of the sky, the image capturing unit 262' roughly adjusts the solar panel 24, so that the second solar image captured by the image capturing unit 262 is close to the first solar image, and then the lens is used. Taking the sun image to precisely match the second sun center of the second sun image to the first sun center of the first sun image 'The solar power system 2 ~ T is more accurately aligned with the sun. -15- 200944731 ^ In addition, in the present invention In another embodiment, the first solar image can also be obtained by the shirt image capturing unit 262, and is not limited to a preset. A conventional solar tracker tracks the sun with poor accuracy, so that the solar cell generates electricity. When the amount is not high, and the tracker is hidden in the cloud for a period of time, it is not easy to continue tracking the sun. The present invention uses the image comparison method to make the sun tracking device Exactly aligning with the sun, 1 can predict the position of the next moment of the sun, and the effect of the synchronization with the solar essence on the solar cell can also increase the amount of solar cell power generation. Although the invention is disclosed in the foregoing embodiments The above is not intended to limit the scope of the invention, and the scope of the invention is defined by the scope of the invention as defined in the appended claims.
