Abstract

The invention discloses a sunlight tracking detector with dual daylighting tubes in combination with photosensitive sensors in *-shaped arrangement. The sunlight tracking detector comprises a lightproof round tube I arranged on a vertical mounting face and a lightproof round tube II arranged on the vertical mounting face, and the round tubes I and II are laminated; the bottom in the round tube I is provided with a plurality of photosensitive sensors in the *-shaped arrangement; the bottom in the round tube II is provided with one photosensitive sensor; the inner diameter of the round tube I is more than that of the round tube II; and the height of the round tube I is more than the maximal length of the plurality of photosensitive sensors in the *-shaped arrangement along the mounting face, and the height of the round tube II is more than that of the round tube I and is smaller than or equal to 10 times the inner diameter of the round tube II. According to the sunlight tracking detector disclosed by the invention, the thick and thin tubes are combined with the photosensitive sensors in the *-shaped arrangement, so that not only is a monitoring range enlarged by virtue of the characteristics of large inner diameter and low height of the thick tube, but also the plurality of photosensitive sensors in the *-shaped arrangement can be used to measure light from multiple directions at the same time, and thus, the sunlight tracking detector has the characteristics of wide detection range and high detection precision.

Description

technical field [0001] The invention relates to sunlight tracking technology, in particular to a sunlight tracking detection device with double-tube lighting of different thicknesses combined with a rice-shaped arrangement of photosensitive sensors for light sensing. Background technique [0002] The existing tubular daylighting combined with photosensitive sensor mode sunlight tracker mainly uses a single tube daylighting combined with a sunlight tracking detection device arranged along the circumference of the tube to detect light with a photosensitive sensor. A photosensitive sensor is installed at a certain angle (generally 90 degrees) on the outer side of the tube wall along the tube circumference. When the photosensitive sensor outside the tube wall detects no light, it is deemed to have reached the required rotation angle, and the equipment rotates to the outside of the tube circumference. If the values ​​of each photosensitive sensor are consistent, it can be conside...
