GPS-based two-freedom-degree sun tracking system

Abstract

The invention discloses a GPS-based two-freedom-degree sun tracking system in the field of a sun tracking system. The GPS-based two-freedom-degree sun tracking system comprises a GPS module; the signal output end of the GPS module is connected with the signal input end of a MAX232 chip; the signal output end of the MAX232 chip is connected with the signal input end of a single-chip microcomputer; the signal output end of the single-chip microcomputer is connected with the signal input end of a stepping motor driver; the signal output end of the stepping motor driver is respectively connected with the signal input ends of a vertical motor and a transverse motor; and the signal output ends of the vertical motor and the transverse motor are both connected with a concentrator through a holder. The GPS-based two-freedom-degree sun tracking system has the advantages of high control precision, high flexibility, easy operation, high coupling ratio, low cost, full automatic tracking, and green, environmental-friendly, energy-saving and healthy indoor illumination, thereby being suitable for the control of the concentrator.

Description

technical field [0001] The invention relates to a solar tracking system, in particular to a dual-degree-of-freedom solar tracking system. Background technique [0002] In recent years, as urban buildings tend to be high-rise and dense, traditional lighting methods alone cannot meet the lighting requirements inside buildings. Especially those lower buildings, windowless rooms and basements, even in sunny weather, the interior is dark and gloomy, which increases the power consumption of artificial lighting invisibly, and affects the physical and mental health of people who live and work in this environment for a long time. adverse effects on health. The technology of directly introducing sunlight into the room for lighting not only makes full use of sunlight resources, reduces the waste of electric energy during the day, meets the lighting needs of windowless rooms and basements, but also improves the quality of indoor life. [0003] At present, many scholars at home and abr...

AI Technical Summary

Problems solved by technology

[0004] Although some fiber optic light guide indoor lighting systems at home and abroad have their own advantages in different aspects, there are more or less shortcomings in the actual application process, such as large errors, poor flexibility, non-all-weather tracking, and serious light pollution.
