Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] The existing solar light tracking system is subject to many restrictions on the tracking angle. In the morning or evening, or when the sun is covered by clouds for a long time on a cloudy day and the sun appears again, the light may only be irradiated on the wall of the shading tube. The tracking system can't work. It can only be considered to adjust the tracking of sunlight, which makes the tracking system very inconvenient to use.

[0015] In this embodiment, the sunlight direction detection sensor is used to solve the above problems, which can realize continuous tracking of sunlight in a wide range and without blind spots. Specifically, as figure 1 and 2 , is a sunlight direction detection sensor, comprising a base 1 and a light-shielding cylinder 2 arranged on the base 1, the top of the light-shielding cylinder 2 is provided with a light through hole 3, and...

Abstract

The invention relates to the technical field of sensors, in particular to a sunlight direction detecting sensor within a large-angle range. The sunlight direction detecting sensor comprises a base and a shading barrel arranged on the base, a light through hole is formed in the top of the shading barrel, a four-quadrant sensor is arranged at the bottom of the shading barrel, a lens is arranged between the light through hole and the four-quadrant sensor, and at least eight phototubes are uniformly arranged in the circumferential direction of the shading barrel. The sensor is large in tracking range and capable of achieving blind-zone-free continuous tracking within the +/-80 degrees with the axis of the four-quadrant sensor as the center and has the advantages of being simple in structure, high in detection accuracy and convenient to use.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a solar light direction detection sensor with a large angle range. Background technique [0002] With the development of solar photovoltaic power generation technology in recent years, high-precision sunlight tracking technology is becoming more and more important, and its tracking accuracy directly affects the power generation efficiency of solar photovoltaic power generation systems. In the existing tracking system, a separate photoelectric sensor is usually used to detect the direction of sunlight. These sensors use different photosensitive elements, such as photodiodes, phototransistors, photocells, and photoresistors. It can only judge the general orientation of the sun, but cannot make quantitative judgments, let alone accurate detection. In order to improve the tracking accuracy, four-quadrant photoelectric sensors are usually used to detect the direction of sunlight at p...
