Abstract

The invention relates to a solar tracking device, in particular to a solar tracking device based on bionic polarized light detection. Extraction of the polarization angle and degree of polarization in an atmospheric polarization mode is achieved through polarized light detection sensors by imitating a compound eye navigation model. Firstly, a central control and information processing unit drives an actuating mechanism of a horizontal servo motor according to the included angle between the solar azimuth and polarization angle output by two polarized light sensors on a horizontal tracking physical structure unit, and then solar azimuth direction tracking is achieved; then, the central control and information processing unit controls an actuating mechanism of a vertical servo motor to rotate according to degree-of-polarization information output by two polarized light sensors on a vertical tracking physical structure unit, and then solar altitude direction tracking is achieved; finally, fine adjustment of two platforms is carried out through output of a natural light sensor. In this way, solar tracking is successfully achieved through the solar tracking device based on bionic polarized light detection.

Description

technical field [0001] The invention relates to a sun tracking device, in particular to a sun tracking device based on bionic polarized light detection. Background technique [0002] For a long time, energy has been the material basis for human survival and development. Solar energy has obvious advantages in energy development: non-polluting, economical, abundant reserves, and universality. It is precisely because of these characteristics that the rational development and utilization of solar energy has become a hot technology that is widely concerned by countries all over the world. [0003] However, despite the above advantages of solar energy, there are still many problems in the utilization of solar energy. Solar energy has the disadvantages of dispersion, instability, low efficiency and high cost, which put forward higher requirements for the collection and utilization of solar energy. How to maximize the utilization of solar energy is still a research hotspot of sch...
