或夕個光感知&所得到的訊號來驅動動力系統追 蹤裝置調整至朝向太陽之位置。如圖1及圖2所示，習知 太陽追蹤器1包含-*透光之殼體12，殼體12上裝 -聚光管Μ ’於殼體12底端有一_區16，聚光管14 垂直投影至偵舰16。仙m 16之四職設有四個光感 知器18。 —當太陽位於聚光管14正上方時，太陽光線〜穿過聚 光官14而投射至B區域時，此時太陽追蹤器1並不會移 動。待經一段時間後，太陽朝右偏移至聚光管14右方一 定角度時’照射之光線a2穿過聚光管14而投射至B區域 周圍之光感知器18上’光感知器18感知光線後，即驅動 動力系統（圖未顯示)微調太陽追蹤器1的位置，如此太陽 照射之光線又回至B區域中。系統不斷重複運作，使追蹤 器能永遠面向太陽，達到追蹤太陽之目的。 然而利用光感知器18感測太陽光以調整太陽追蹤器 1之方式，皆需在光感知器18感知後，才調整太陽追蹤器 1338767 1位置’故太陽追蹤器1實際對準太陽之準確度，會由剛 調整完時最準確(誤差最小）而隨時間經過而逐漸降低，直 至下一刻光感知器18又再度感知時(誤差最大），再度調整 太陽追蹤器1之位置，準確度才會又變的準確，如圖3所 示。 而若用在太陽能發電上，太陽能電池之發電效率會隨 著太陽能電池朝向太陽之準確度愈高，發電量愈多，而準 確度愈低時，發電量亦愈少。故對照於圖3，習知太陽追 蹤器1運用於太陽能發電上時，其如圖4所示。在時間t=0 時，太陽能追蹤器1與太陽之準確度誤差最小，故太陽能 么電里表大(Emax)，而隨時間經過，至t=ti時，準確度誤 差達到最大，此時發電量最小(Emin)。而此時光感知器18 亦偵測到太陽光，故調整太陽追蹤器丨，太陽追蹤器又再 度對準太陽，從而發電量又達到最大。由圖4觀之，在t=〇 至t=ti的這段期間，太陽能發電量係由最大變至最小。明 顯得知，實際發電效率並不高。故以此方式作動之太陽追 蹤器1用於太陽能發電上，效果並不佳。 再者，當太陽朝聚光管14兩側偏移時，且其投射光 線超過B區域而至a區域時，太陽追蹤器丨會因為A區 域已無光感知器18存在，故無法再調整追縱太陽。此常 t生於天空有雲層出現時，遮住太陽一段時間，而此段時 間光感知器18無法感應太陽投射光線，而待雲層散去後， 追縱器丨容易迷失太陽位置而無法再追蹤太陽。 1338767 此外’以光感知器18感知太陽光，而作動太陽追縱 β 1調整其位置面向太1¾之方式，因為B區域面積仍大， 故太追縱器1面向太陽容易不甚準確，此亦造成太陽追 蹤器1面向太陽準確度有限之問題。 故如何使太陽追蹤器實際面向太陽之準確度提升，且 於雲層散去後，仍可繼續追蹤到太陽；且使用此追縱器於 太1¼ at»電池上時，可南發電量，為本發明所欲解決之課 題。 【發明内容】 由於習知太陽追蹤器追蹤太陽之準確度不佳，故相對 使太陽能電池發電量不高，且追蹤器於雲層遮住一段時間 後，不易繼續追蹤太陽。故本發明之目的在於提供一種以 影像比對方式以追蹤太陽之太陽追蹤裝置。其可利用影像 比對，使太陽追蹤裝置準確地對準太陽，且 = -刻之位置，達到與太陽實質同步之功效。== 池上時，亦可大符提高太陽能電池發電量。有效解決先前 技術所存在的問題或缺點。 為達上述目的，本發明提供一種太陽追蹤裝置，係搭 配一動力裝置而動作，太陽追蹤裝置包含：一記憶單元， 儲存有H陽影像；—影像擷取單元，係於特定時間 間隔擷取太陽之1二太陽影像；以及1像處理單元， 根據第-太陽影像與第二太陽影像比較而得到—差異資 料’並儲存於記憶單元；其中，太陽追縱裝置係根據差異 1338767 資料以致動動力裝置。 此外，本發明亦提供一種太陽能發電系統，包含：一 太陽能面板；一動力裝置，用以調整太陽能面板；以及一 太陽追縱裝置’包括：一記憶單元’儲存有一第一太陽影 像；一影像擷取單元，係於一特定時間間隔擷取太陽之一 第二太陽影像；以及一影像處理單元，根據第一太陽影像 與第二太陽f彡像比㈣得f，卜差異資料，並儲存於記憶單 元；其中，太陽追蹤裝置係根據差異資料以致動動力裝 置，俾能使得太陽能面板朝向太陽以收集太陽能量。 利用上述本發明之技術特徵，可達到下列功效： 1. 提高太陽追職置與太陽之鮮度，且亦提高太陽能 電池之發電效率。 2. 可大角度搜尋天空中任—處之太陽，於雲層遮住一段 時間後’也不會迷失太陽位置。Or the signal obtained by the light perception & to drive the powertrain tracking device to adjust to the position of the sun. As shown in FIG. 1 and FIG. 2, the conventional solar tracker 1 includes a -* light-transmissive housing 12, and the housing 12 has a concentrating tube Μ' at the bottom end of the housing 12 having a _ area 16, a concentrating tube. 14 Project vertically to the ship. There are four light sensors 18 in the fourth position of Xian M 16 . - When the sun is located directly above the concentrating tube 14, the sun ray ~ is projected through the concentrating light 14 to the B area, at which time the sun tracker 1 does not move. After a period of time, when the sun is shifted to the right to a certain angle to the right of the concentrating tube 14, the illuminating light a2 passes through the concentrating tube 14 and is projected onto the light sensor 18 around the B area. After the light, the driving power system (not shown) fine-tunes the position of the sun tracker 1 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 1338767 after the light sensor 18 senses, so the accuracy of the sun tracker 1 actually aligning with the sun. , will be the most accurate (minimum error) just after the adjustment, and gradually decrease with time, until the next moment the light sensor 18 is again perceived (the error is the largest), and then adjust the position of the sun tracker 1 again, the accuracy will be It has become more accurate, as shown in Figure 3. If it is used in solar power generation, the power generation efficiency of solar cells will increase with the accuracy of solar cells facing the sun, and the more power generation, the lower the accuracy, the less power generation. Therefore, referring to Fig. 3, when the conventional solar tracker 1 is applied to solar power generation, it is as shown in Fig. 4. At time t=0, the accuracy error between solar tracker 1 and the sun is the smallest, so the solar energy meter has a large (Emax), and over time, when t=ti, the accuracy error reaches the maximum. The minimum amount (Emin). At this time, the light sensor 18 also detects the sunlight, so after adjusting the sun tracker, the sun tracker is again aligned with the sun, and the power generation is maximized. As seen from Fig. 4, during the period from t = 〇 to t = ti, the amount of solar power generation is changed from maximum to minimum. It seems that the actual power generation efficiency is not high. Therefore, the solar tracker 1 activated in this manner is used for solar power generation, and the effect is not good. Furthermore, when the sun is deflected toward both sides of the concentrating tube 14, and the projected light exceeds the B area to the a area, the sun tracker 无法 will have no light sensor 18 in the A area, so the tracking cannot be adjusted. Longitudinal sun. This constant t is born in the sky when there are clouds, covering the sun for a while, and this time the light sensor 18 can not sense the sun to project light, and after the clouds are scattered, the tracker is easy to lose the sun position and can no longer track sun. 1338767 In addition, the light sensor 18 senses the sunlight, and the sun chases the β 1 to adjust the position of the surface to be too 13⁄4. Because the area of the B area is still large, it is not easy to accurately track the sun to the sun. Causes the Sun Tracker 1 to face the limited accuracy of the sun. Therefore, how to improve the accuracy of the sun tracker to the sun, and continue to track the sun after the clouds are scattered; and when using this tracker on the battery, it can generate electricity. The subject to be solved by the invention. SUMMARY OF THE INVENTION Since the accuracy of tracking the sun by the conventional solar tracker is not good, the solar cell is relatively low in power generation, and the tracker is difficult to continue tracking the sun after being covered by the cloud for a period of time. It is therefore an object of the present invention to provide a solar tracking device for tracking the sun in an image alignment manner. It can use the image comparison to make the sun tracking device accurately align with the sun, and = - engraved position to achieve the effect of synchronizing with the sun. == When the pool is on, it can also increase the amount of solar cell power generation.

And the image processing unit obtains the difference data according to the comparison between the first sun image and the second sun image and stores the data in the memory unit; wherein the sun tracking device is based on the difference 1338767 data to actuate the power device . In addition, the present invention also provides a solar power generation system comprising: a solar panel; a power device for adjusting the solar panel; and a solar tracking device comprising: a memory unit storing a first solar image; Taking a unit, taking a second solar image of the sun at a specific time interval; and an image processing unit, according to the first solar image and the second solar image ratio (4), obtaining the difference data, and storing the data in the memory The unit; wherein the solar tracking device actuates the power device based on the difference data, and the solar panel can face the sun to collect the amount of solar energy.

The features and advantages of the present invention are described in detail below, and the content of the present invention is sufficient for any skilled person to understand the technical contents of the present invention and according to the contents disclosed in the specification, the scope of the patent application, and FIG. The subject matter of the present invention is to be understood by the following description of the present invention and the following description of the embodiments of the present invention in order to demonstrate and explain the principles of the present invention, and to limit the present invention. Further understanding of the objects, structures, features, and functions of the invention will be described in the following detailed description. Referring to Figure 5, there is shown a schematic view of the structure of the solar power generation system 2 of the present invention. The solar power generation system 2 of the present invention comprises a support column 22, a solar panel 24, a solar tracking device % and a power unit 28. The pillars 22 are - upright pillars to support the entire system. The solar panel 24' absorbs sunlight and converts the light energy into electrical energy, which has a direct light plane 24a which is identical to conventional solar panels. It is set on the reading column 22 and is rotatable in all directions on the support column 22. Please refer to FIG. 6' for a block diagram of the solar tracking device 26 of the present invention. The sun 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 includes an optical component 261, a shirt image capturing unit 262, and an image processing unit 263 and 13.38767 adjustment system. And tracking the sun. - A memory unit 264 for storing various materials and providing a tribute of the complex storage to the image processing unit. In the embodiment of the present invention, the memory unit 264 stores the data of the compared data and the mobile track of the data processed by the image processing unit, and also provides the originally stored data to the image $ unit 263. • A power unit 28 is disposed on the support column 22, such as a motor (not shown) to provide power to drive the solar panel 24 to rotate on the column 22 so that the 1% energy panel 24 is facing the sun. The configuration of 28 is similar to the conventional solar power generation system. 〆, 白 The operation of the solar power generation system 2 of the present invention controls the solar panel 24 to accurately generate electricity into the solar power by means of image matching. First, the optical element 261, such as a focusing lens, is used to focus the solar image onto the image capturing unit 262 after focusing by the optical element 261. The image capturing unit 262 optically captures the sun image, which captures 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 capturing unit 262 can capture a plurality of second solar images for a period of time. For example, if the specific time interval is set to 1 second, the image capturing unit 262 can capture 60 second solar images in one minute. 12 1338767 The memory unit 264 is pre-stored with a first sun image, and the first sun image is a preset sun image having a first sun center. Please refer to FIG. 7' for an image comparison of the image processing unit 263 of the sun tracking device 26. The first solar image 2642 is in the image processing unit 263, and the position of the scene image 2642 in the screen 2632 is fixed. When the image capturing unit 262 transmits the signal of the second solar image 2622 captured by the image capturing unit 263 to the image processing unit 263, a second solar image 2622 of a sun shape is formed at a position of the surface 2632. And has a second solar center 2624. The image processing unit 263 compares the first solar center 2644 of the first solar scene image 2642 remembered by the memory unit 264 with the second solar center 2624 of the second solar image 2622, since the second solar center 2624 is 昼The position on the face 2632 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 micro error χ(Δχ) and small error y (△). This means that the solar panel 24 is facing the sky at the moment and the actual sun position in the sky has Δχ and no error. At this time, the image processing unit 263 stores the difference data in the memory unit 264 to provide a function for pre-actuating the power unit 28 in the future. At the same time, the power unit 28 is immediately actuated according to the difference data, and the solar panel 24 is adjusted. In this way, the second solar center 2624 of the second solar image 2622 captured in the next second is matched with the first solar center 2644 of the first solar image %", so the solar surface f 24 of the solar power generation system 2 is accurate at this time. The ground is aligned with the sun. When there are clouds in the sky to cover 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 sun The image 2642 is preset, -13- (S; 1338767 is used as a reference for the second solar image 2622 alignment, so the position of the image in the surface 2632 is fixed. If the second solar center 2624 of the captured 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 directly facing too much. At each specific time interval, the unit 262 will take a second solar image 2622 and image it at the image processing unit 263. Therefore, each time a second solar image 2622' is generated, the image processing unit 263 will The first solar image 2642 is compared to obtain a difference data, and then the power device 28 is actuated to adjust the solar panel 24 to the solar field. The solar panel 24 can be positively directed to the sun. And the first solar image 2642 and the first %景;^Compared with 2622, the difference between the displacements of the sun's center position is obtained by comparing the two solar centers 2624 and 2644 to adjust the second solar center 2624 of the first solar image 2622 and the first solar center 2644. Matching, so the solar panel 24 can accurately positively improve the accuracy of the sun. = As shown in Fig. 8 and Fig. 9, the image capturing unit of the solar power generation system of the present invention captures the second sun shadow. For a specific time interval, it can be set very short (such as one second) and the solar panel 24 (see Figure 5) is accurate to the accuracy of the sun, as shown in Figure 8. The error value is quite low. Because of this, the power generation energy f of the solar power generation system 2 can reach the level of the phase #, and the power generation amount is effectively increased. In addition, in the other embodiment of the invention, the solar tracking device 26 L unit 264 can also store the recorded data of the past trajectory of the sun. 'This sorcerer data can include the previous day, last year, or four years ago (because every -14·13,387,767 • four years of running, the sun The running track will be any one of four years and one cycle. The memory unit 264 can provide the image processing unit 263 with the information to pre-activate the power unit 28. For example, the memory unit 264 & provides the mobile trajectory data of the sun four years ago in the image processing unit 263, and after the image processing unit 263 is operated by the software, the power device 28 can follow the data second to the next second of the sun movement. Before the clock (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 achieve the "synchronization" with the too IW. And using this recorded data, when the solar power generation system 2 is used, the solar power generation system 2 can also provide the image to the image by using the moving track data of the sun stored in the memory unit 264 even after the cloud layer covers the sun for a period of time. The processing unit 263 activates the power unit 28, so that the solar power generation system 2 can accurately find the sun and accurately align the sun when the sun is reappeared after the sun is covered by the cloud. 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, and the wide-angle lens is a lens of about 180 degrees, which can focus on any image of the sun in the sky in the image capturing device. . Thus, the solar power generation system 2 can capture the second solar image regardless of whether the sun is in the sky or not. In addition, the lens can be used simultaneously with the wide-angle lens. First, the wide-angle lens is used to focus the solar image in any part of the sky. The image capturing unit 262' is used to roughly adjust the solar panel 24 so that the second solar image captured by the image capturing unit 262 is close to After the first sun image, the lens is used to capture 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, so that the solar power generation system 2 can more accurately align with the sun. Further, in the other embodiment of the present invention, the first sun image shirt operation unit 262 is operated, and is not limited to being set in advance. In order to keep track of the sun, the accuracy of the sun tracking device is not good. Therefore, it is also possible to generate electricity for 4 years, and chasing (4) after covering the # layer for a period of time, ^ is not easy to continue tracking the sun. The invention utilizes an image comparison method to accurately align the sun and trace device with the sun, and predict the position of the sun in the next moment.
