Diffusion scattering sunlight tracking sensor

Abstract

The invention provides a diffusion scattering sunlight tracking sensor comprising a light collection cylinder (1), a light absorbing material (2), a diffusion scattering layer (3), a reflective layer (4), a photoelectric sensor (5) and a substrate (6). The light collection cylinder (1) is installed at the substrate (6); the diffusion scattering layer (3) is located at the middle of the light collection cylinder (1); and the inner wall, above the diffusion scattering layer (3), of the light collection cylinder (1) is coated with the light absorbing material (2). A central light through hole (3-1) is formed in the diffusion scattering layer (3); the photoelectric sensor (5) is arranged below the central light through hole (3-1) and is installed on the substrate (6); and the inner wall, below the diffusion scattering layer (3), of the light collection cylinder (1) is coated with the reflective layer (4). The provided diffusion scattering sunlight tracking sensor with advantages of high adaptability, simple structure, and low energy consumption is an ideal sunlight tracking device.

Description

technical field [0001] The invention relates to a solar azimuth tracking sensor device, which can be used alone or in combination with other tracking methods. Background technique [0002] Due to the changing angle of the sun, in the current method of using solar power to generate electricity, in order to improve the power generation efficiency and receive as much sunlight as possible in a limited area, it involves the problem of sunlight tracking, that is, how to make the incident direction of sunlight coincide with the received sunlight. The device normal is vertical. The current sunlight tracking schemes mainly include sun trajectory calculation, photoelectric sensor tracking and current detection tracking, among which photoelectric tracking mainly includes light and shadow method and electrical signal analysis and comparison method. Existing photoelectric sensing solutions generally require multiple sensors, poor accuracy, narrow acquisition range, and poor environmenta...

Problems solved by technology

Existing photoelectric sensing solutions generally require multiple sensors, poor accuracy, narrow acquisition range, and poor environmental adaptability. Generally, a separate linear optical sensing element is required to collect light intensity to determine whether it is cloudy , which not only increases energy consumption, but also increases the cost
