Sun tracking device and tracking method thereof

Abstract

The invention relates to a sun tracking device which comprises a projection identification device, a lightproof baffle plate, a projection identification device casing, a server and a rotary device, wherein the lightproof baffle plate is vertically arranged on the upper bottom of the projection identification device casing, the projection identification device for identifying projection of the lightproof baffle plate on the upper bottom of the projection identification device casing is arranged in the projection identification device casing, the projection identification device casing is arranged on the rotary device, the signal output end of the projection identification device is connected with the server, and the server controls the rotary device to rotate. The error of measurement result of the actual elevation angle and the horizontal angle of the sun is within 5 degrees.

Description

technical field [0001] The invention relates to the field of sun tracking, in particular to a sun tracking device. Background technique [0002] In order to solve the problem of limited traditional energy, while taking into account the protection of the ecological environment, countries around the world are currently making efforts to develop and utilize sustainable and clean new energy, such as solar power generation. Although solar energy has many advantages, there are still many problems in its development and utilization. The most prominent problem is the low photoelectric conversion efficiency. This problem can be considered and studied from two aspects: one is to use photoelectric conversion materials with higher conversion efficiency, which still requires long-term research and development by researchers; There are technologies to solve this problem. [0003] At present, there are mainly two methods of solar ray tracing: photoelectric and mechanical. The photoelect...

AI Technical Summary

Problems solved by technology

The above two methods still have some technical problems in practical application: the anti-interference ability of the photoelectric tracking method is weak, and the accuracy is low; the effect of the mechanical tracking method is not satisfactory due to the increase of cumulative error

[0009] Compared with photoelectric and mechanical tracking technologies, the above two new sun tracking technologies can effectively improve the tracking effect of photoelectric and mechanical sun tracking. application

To sum up, the existing sun tracking technology cannot fully meet the actual needs, so it is imminent to study a sun tracking system with wide application range, accurate tracking, simple structure and low cost.
