Abstract

The invention discloses a high-accuracy sun position detecting device and an automatic detecting method thereof. The high-accuracy sun position detecting device comprises an SCM (Single Chip Microcontroller), a first stepping motor, a second stepping motor and four photoelectric receiving circuits, wherein the first stepping motor, the second stepping motor and the four photoelectric receiving circuits are respectively connected with the SCM; each photoelectric receiving circuit comprises a photoelectric receiving tube connected with the SCM; an output shaft of the first stepping motor is vertically and upwards arranged and is in axial rotation; the second stepping motor is connected to the output shaft of the first stepping motor; an output shaft of the second stepping motor is horizontally arranged and is in axial rotation; the output shaft of the second stepping motor is connected with a rotating fan blade which is parallel to a vertical plane; the four photoelectric receiving tubesare uniformly and fixedly arranged at arc-shaped edges of the rotating fan blade. The high-accuracy sun position detecting device disclosed by the invention adopts the four photoelectric receiving tubes for tracking and detecting the sun, so that the measurement accuracy is greatly increased, and the application of solar energy having high focusing requirement can be met; two stepping motors in different rotating directions are adopted for collecting optimum three-dimensional focusing positions of the solar energy, the detecting accuracy is high, and the detection is fast and accurate.

Description

Technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a high-precision solar position detection device and an automatic detection method thereof. Background technique [0002] In our country, the development of new energy is vigorously promoted. As a clean and long-lasting energy, solar energy has great development potential. The current fixed solar energy receiving utilization rate is too low. If you want to improve the solar energy receiving utilization rate, you must adopt tracking and receiving. The prerequisite for tracking and receiving is to detect the position of the sun. The current tracking technology uses methods such as solar track tracking, photoelectric tracking and hybrid tracking. However, the cost of the existing high-precision solar position detection device is too high, and the low-cost accuracy cannot meet the requirements, which restricts the tracking and utilization of solar energy. Summary of the...
