Problems solved by technology

Since the four-quadrant detector needs to continuously sample and scan the light source during working hours to determine the position information of the light source, and then control the position and angle of the light source receiving instrument, the entire detection process and detection method are quite complicated and time-consuming, and The update rate of sampling is not high, and it is easy to cause large errors in the judgment results, so it is impossible to effectively judge the accuracy of the incident light source
On the other hand, compared with parallel sunlight, there is currently no detection method for non-parallel light sources.

Embodiment Construction

[0047] Such as figure 1 As shown, the light source detection system 1 of the present invention is applied to measure the position information and intensity information of the incident light source. device 14. There is a central reference point on the imaging plate 10 for receiving the incident light source. There is a light hole on the spot modulation plate 11, which is arranged parallel to the vertical normal of the central reference point of the imaging plate 10, so as to receive the incident light source through the light hole, and form a light hole on the imaging plate 10. a spot of light. The image acquisition device 12 is used to acquire the image of the light spot, and the radiation detection device 14 is used to detect the light intensity division (ie, the distribution area of ​​the radiation amount) of the light spot. The processing device 13 is used to identify the image of the light spot and the light intensity division, so as to calculate the position informatio...

Abstract

The invention provides a method and a system for detecting a light source, wherein the method comprises the following steps: receiving an incidence light source through the through holes of a light spot modulating plate to form a light spot on an imaging plate; then, obtaining the image of the light spot and detecting the light intensity distribution region of the light spot to regionalize the intensity of the light spot, transmitting the image of the light spot and the light intensity regions to a processing device; and finally, identifying the image of the light spot and the light intensity regions by utilizing the processing device so that a light source position signal and intensity information corresponding to the light spot through a preset algorithm. Thus, the invention solves the problem that the receiving / reflecting position and angle of the set light source are correspondingly adjusted along with the radiation angle of sunlight in the prior art, thereby prompting the more accurate judgment and more efficient utilization of users on the position of the incidence light source.

Description

【Technical field】 [0001] The present invention relates to a light source detection method and system, in particular to a method and system for measuring the position and intensity information of an incident light source. 【Background technique】 [0002] With the promotion of the concept of environmental protection, the utilization of green and pollution-free energy such as wind energy, water energy, and light energy has attracted more and more attention, among which light energy has attracted the most attention. Take solar energy as an example, because solar energy has been regarded as the most stable energy source so far, and it will not gradually consume energy due to use at all. Therefore, it has been widely recognized in the world. [0003] The altitude angle of sunlight not only changes with the time of day, but also changes in azimuth due to different seasons. Existing products for detecting light sources, such as solar photovoltaic panels, are usually equipped with in...
