Automatic sunlight following positioning device, method and system

Abstract

The invention discloses an automatic sunlight following positioning device, method and system. The positioning device comprises a daylighting panel used for judging the angle between the sunlight radiation direction and the sunlight acquisition surface of solar energy equipment, the daylighting panel comprises four rectangular photocells with the same size and a cross-shaped light baffle, wherein the photocells are fixed to the same plane in a shape like a Chinese character 'tian', the light baffle is fixed to a cross-shaped junction line in the shape like the Chinese character 'tian', the plane where the light baffle is located and the plane where the photocells are located are perpendicular to each other, and the daylighting surface of the daylighting panel can synchronously rotate along with the sunlight acquisition surface of the solar energy equipment and is always parallel to the sunlight acquisition surface of the solar energy equipment. The daylighting panel is simple in structure, reliable in stabilization, accurate in positioning, and capable of being quickly and automatically restored and positioned towards the sunlight collineation direction in the intermittent sunlight collineation climate or the low-illumination change environment.

Description

technical field [0001] The invention relates to an automatic sunlight tracking positioning device, a positioning method and a positioning system, in particular to an automatic sunlight tracking positioning device and a positioning system for solar energy equipment, belonging to the field of tracking and positioning. Background technique [0002] For some solar equipment that uses sunlight for daylighting, in order to make the sunlight-acquiring surface of the solar equipment vertically face the sunlight and obtain the maximum solar energy, it is necessary to use a sunlight positioning device. However, the lighting device of the current daylight positioning device adopts multiple photosensitive elements, and locates the sunlight direction by comparing the difference in the photosensitive intensity of each photosensitive element. Small, the positioning error is large. In order to improve the accuracy of sunlight positioning, there are now methods that reflect the sunlight and...

However, the lighting device of the current daylight positioning device adopts multiple photosensitive elements, and locates the sunlight direction by comparing the difference in the photosensitive intensity of each photosensitive element. Small, large positioning error

In order to improve the accuracy of sunlight positioning, there are now methods that reflect the sunlight and then use the photosensitive element to collect light, set a grating baffle in front of the photosensitive element and then collect light, or add a single-chip microcomputer to improve the accuracy of positioning by calculating the amount of light received by the photosensitive element. Sexuality, but not direct lighting, most of the structures of this structure are relatively complex, and usually cannot be automatically and normally positioned under the lighting conditions of complex and changing climates
