Description of the Invention: [Technical Field] The present invention relates to a method for detecting sunlight, and more particularly to a method for measuring the direction of sunlight that can be used to easily and accurately detect the orientation of the sun. [Prior Art] The conventional method of detecting the sunlight is to measure the sunlight by a detecting device as shown in the second drawing; the detecting device comprises a half-circle bracket 8 and a plurality of solar panels 9 The semicircular bracket 8 is disposed along the east-west direction; the plurality of solar panels 9 are equidistantly disposed on the semicircular bracket 8 such that each of the solar panels 9 can face several directions respectively toward the sky; wherein, due to the sun-orientation The change will relatively affect the angle of illumination of the solar panel 9, thus affecting the intensity of illumination of the solar panel 9. The conventional method of detecting the sunlight is that the solar panel 9 can convert it into a thin electric energy relative to the solar energy according to the intensity of the absorbed solar energy, and then use the solar panel that is facing the sun. 9 is the principle of generating a relatively large voltage due to the relatively strong illumination of the sunlight. Therefore, through the solar panel 9 that generates the maximum voltage, it is known that the solar panel 9 corresponding to the maximum voltage is facing. Orientation. - In general, the above-mentioned conventional solar radiation detection method has the following disadvantages. For example, since the number of solar panels 9 is limited, each solar panel 9 corresponds to a certain range of solar orientation, even if it is known that the sun is located. Within the corresponding azimuth of the maximum voltage solar panel 9, only the solar orientation can be roughly estimated, and an accurate solar direction cannot be obtained. For the above reasons, it is necessary to further improve the above-mentioned conventional method of detecting sunlight. The main object of the present invention is to provide a method for detecting the direction of sunlight, which utilizes a plurality of solar panels oriented in different orientations, and the solar light detected by the plurality of solar panels collectively determines the accuracy. The orientation of the sun makes the invention have the effect of improving detection accuracy. According to the solar light detecting method of the present invention, the method comprises the steps of: a standard data capturing step, which is performed by a solar panel lying on the ground, which is irradiated by different sunlight to the sunlight. The generated standard data 'normalizes the standard data to obtain a test standard relationship chart; a detection step, which is obtained by taking a plurality of solar panels oriented in different directions by a sunlight to be measured Detecting data; and a positioning step of dividing each detected data measured by each solar panel by the measured maximum detected data to complete normalization, and then normalizing the detected data The ratio is correspondingly substituted into the detection standard relationship chart to obtain an angle of the sunlight of the solar energy to be measured with respect to each solar panel, and the solar radiation is corrected by the deflection angle of the solar panel with respect to the ground. The sun's rays. Thereby, the present invention has the effect of improving detection accuracy. The above and other objects, features, and advantages of the present invention will become more apparent <RTIgt; <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; Referring to Figures 2 and 3, the solar light detecting method of the present invention comprises a standard data capturing step si, a detecting step S2 '... 疋{立200933104, step S3. The standard data capture step S1 is used to capture standard photoelectric data through a solar panel 10, and obtain a standard relationship diagram of the standard data relative to the angle of the sunlight; and then capture the detection step S2 A plurality of different solar panels 10 are subjected to detection data generated by illumination of a sunlight to be measured; finally, the positioning step S3 is used to locate the sunlight of the sunlight to be measured. Referring to FIG. 3, a standard data capturing step S1 of the solar light detecting method according to the preferred embodiment of the present invention is performed by using a flat barrier plate 10' placed on the ground to receive different sunlight directions. The standard data that should be generated by the sunlight of the angle is normalized, and the standard data is normalized, and the standard relationship chart of the normalized standard data relative to the solar angle is obtained. More specifically, the solar panel 1 is laid flat on the ground and the standard data generated by the solar panel 10 under sunlight is obtained, and the sunlight of the sunlight is angled. To 18 baht. The standard data is selected as the voltage value (volts, V), and then the relative relationship between the voltage value and the angle of the sunlight is obtained; since the same sunlight is downward, the _the solar illuminance will also be different. The voltage value is therefore preferably normalized by the voltage values measured by g, and the normalization divides the measured voltage values by the measured maximum voltage value; The voltage ratio is plotted against the angle of the sunlight and is used as the test standard relationship chart. For example, in this embodiment, a solar panel is placed flat on the ground to 'take the voltage value of the corresponding boxing force under the sunlight of different sunlights', and the result is as shown in FIG. 4; Among them, in order to improve the detection of the two issued 200933104, the selection of the solar panel 侧 侧 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 选择 该 该 该 该 该 该 该 该 该 该 该 该 该Group B is the measured value of 5GGGG to 8_G illuminance; Group C is the measured value of 80,000 m illuminance and degree, so that the relative relationship between the electric value and the angle of sunlight can be obtained. Next, divide the voltage value of Figure 4 by the measured maximum voltage value and normalize it as the vertical axis; the body of the sun is deducted by 9G. After the residual money is calculated as the horizontal axis, the relative meaning of the 5th ® can be obtained to avoid the calculation of the negative value caused by the sunlight being deducted by 90 degrees. In addition, in order to improve the detection accuracy, The graphs of the eighth to c groups in Fig. 5 are averaged to form the result of Fig. 6 and serve as a graph of the test standard relationship. Referring to Figures 2, 7 and 8, the detecting step S2 of the present invention is: taking a plurality of detection data generated by the solar panels 10 facing different directions by a sunlight to be measured. More specifically, the plurality of solar panels and the rafts are respectively disposed in different directions facing the sky, and each of the solar panels 10 generates a voltage value by the irradiation of the sunlight to be measured. As shown in the seventh and eighth embodiments, in the embodiment, six solar panels 10 are selected, which are a first solar panel 11, a second solar panel 12, a third solar panel 13, a fourth solar panel η, and a The five solar panels 15 and the sixth solar panel 16' are selected to be arranged in a semi-circular shape in the east-west direction; the i-:.* the angle between the normal line of the solar panel 11 to the sixth solar panel 16 and the ground; Choose 15°, 45°, 75°, 105°, 135, respectively. And 165. And detect the voltage value generated by the current sunlight to be measured. For example, the first solar panel 11 to the sixth solar panel 16 respectively obtain a voltage value under the sunlight to be measured 200933104, wherein the fourth solar panel 14 obtains the first solar panel 11 to the sixth solar panel. The maximum voltage value of 16 is 13.5V, and the voltage value measured by the second solar panel 12 is 4.3V; the relative maximum voltage value is obtained by the temporary casting of the fourth solar panel 14, and therefore, the fourth solar panel 14 ( 105°) is directly exposed to the sun relative to the other solar panels 10, and the first solar panel 11 to the sixth solar panel 16 are 3 inches. Since the interval is set, it is preliminarily judged that the illumination angle of the sunlight is clockwise or counterclockwise deviation i5 in the normal direction of the fourth solar panel 14. Between (3 〇. + 2), that is, 105. ±15. (90. to 120.). Referring to FIG. 2, the positioning step S3 of the present invention is: dividing each detected data measured by the solar panel by the measured maximum profit data to complete the normalization, and then normalizing the respective The detected data ratio is then substituted into the detection standard relationship chart to obtain the angle of the sunlight of the solar light to be measured with respect to each of the solar panels 10, and is corrected by the deflection angle of each solar panel 10 with respect to the ground. The sunlight direction of the sunlight to be measured can be obtained. More specifically, the normalized detected data ratio is obtained by dividing the detected data measured by the solar panel by the measured value of the detected data. For example, please refer to the figures 2 and 8. In this embodiment, the voltage value measured by the second solar panel 12 is 4.3V divided by the maximum voltage value measured by the fourth solar panel 14 by 13.5V. The normalization of the line can be normalized to a ratio of 4.3/13.5 = 0.32; then the normalized ratio is substituted into the detection standard of Figure 6 _ chart towel's corresponding cosine value is 〇33' and back Obtaining the angle between the second solar panel 12 and the sunlight to be tested 200933104. 7〇.9, finally, the angle of the sunlight of the sunlight to be measured is 45:70'9-25.9 or 115.9 by correcting the deflection angle of the second solar panel 12 and the ground. And another 115.9. The system is located at 90 above. It is reasonable to 12 〇 B. Therefore, the second solar panel 12 can determine that the angle of the sunlight to be measured is 1159. . Of course, it is also possible to estimate the solar light direction of the sunlight to be measured by the voltage value measured by the other solar moon board 10, and then further average the angle of the sunlight that is pushed within a reasonable range to improve Measurement accuracy. Thus, the method of detecting the sunlight of the present invention can be accomplished. s In addition, please refer to FIG. 9 , in addition to the plurality of months of the b plate 10 disposed along the east-west direction, a plurality of solar panels 10 may be additionally disposed along the north-south direction or other directions, respectively, and the invention is respectively The solar light is estimated by the price measurement method to measure the sunlight direction of the sunlight relative to the east-west direction and the north-south direction, so as to make a relatively more accurate solar light direction. As described above, compared with the conventional solar light detecting method, Tan Baixiao roughly estimates the solar orientation from the solar panel 9 which obtains the maximum age of electricity: it has the disadvantage that the measurement accuracy is low. In contrast, the present invention in FIG. 2 utilizes the standard data acquisition step S1 and normalizes the standard data through a solar panel 1 并 and normalizes the standard data to create a detection standard, a relationship chart; The detecting step S2 captures a plurality of different directions of solar energy, and the board 10 is subjected to detection data generated by illumination of a sunlight to be measured; finally, the positioning step S3 locates the sunlight direction of the sunlight to be measured. While the invention has been described in connection with the preferred embodiments described herein, it is intended that the invention may be modified and modified in various embodiments of the present invention without departing from the spirit and scope of the invention. * The technical scope of the invention is protected, and therefore the scope of protection of the present invention is defined by the scope of the patent application. 〇
