Abstract

The invention discloses a bionic celestial structure type sun angle sensing device comprising a celestial sphere and a sea urchin pipe structure, wherein the sea urchin pipe structure comprises a plurality of speculum pipes; an optical sensor is arranged on the outer end of each speculum pipe; a compound eye structure is arranged on one semispherical surface of the celestial sphere; the compound eye structure comprises a plurality of light leak holes are formed on the housing of the celestial sphere; a plurality of light holes allowing light to pass through are formed on the other semispherical surface of the celestial sphere; each light hole is communicated with and fixedly mounted on the inner end of one speculum pipe; the plurality of light leak holes are arranged symmetrically one to one with the plurality of light holes; and the center connection line of a pair of mutually symmetrical light leak hole and the light hole is coincident with the central axis of the speculum pipe arranged on the light hole, and further coincident with one diameter of the body of the celestial sphere. The sun angle sensing device is more direct in measuring data and relatively high in accuracy, andhas certain adaptability to cloudy and overcast weathers; and the device is capable of effectively realizing the sun tracking function.

Description

technical field

[0001] The invention relates to a sun angle sensing device, in particular to a bionic celestial sphere structure type sun angle sensing device. Background technique

[0002] The existing sun tracking sensors have the following types of signal collection: one is to use a photosensitive chip as the core device to receive the illuminance of sunlight, and use the method of quadrant analysis to calculate the direction and angle information of the sun by computer. The second is the image method, that is, according to the position of the light spot image formed by the sun on the image receiving screen, the direction angle information of the sun is reversely calculated, and there are other types of sensors that are basically the same as the above two.

[0003] The above sensors are generally only suitable for use in low-precision environments, and the obtained data is not directly measured, and the required data can only be obtained after multiple calculations. In t...
