A Grating-Based High-Precision Sun Tracking Sensor

Abstract

The invention discloses a high-precision solar tracking sensor based on an optical grating. The high-precision solar tracking sensor comprises a photoelectric receiver, a light pillar, a fixed stripe optical grating, a lens and a fixed unit, wherein obliquely carved stripes are formed in the lower end surface of the light pillar; a cross groove matched with the lower end of the light pillar is formed in the fixed stripe optical grating; vertically carved stripes matched with the obliquely carved stripes are formed in the surfaces of the cross groove in the fixed stripe optical grating; the lower end of the fixed stripe optical grating is installed in the cross groove; the fixed stripe optical grating is installed in the lens; the lens is installed in the fixed unit; a plurality of fixed holes are uniformly formed in the fixed unit; and the photoelectric receiver is installed in the fixed hole through a locker. The sensor disclosed by the invention has a relatively high antijamming capability, so that the measurement accuracy for solar motion displacement is improved. Automatic tracking for the sun can be realized by a solar panel, so that the condition of solar automatic tracking control can be known in real time by a worker, and the solar energy utilization rate of solar equipment is improved.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a high-precision sun tracking sensor based on gratings. Background technique [0002] The problem of energy shortage is an important problem faced by many countries at present. As a clean and pollution-free energy, solar energy has a huge development prospect. my country is a country rich in solar energy resources, making full use of solar energy resources has far-reaching strategic significance for energy. The key to using solar energy is to improve the efficiency of solar panels to collect solar energy. The solar panels receive direct sunlight, thereby obtaining the maximum sunlight intensity of the sun, thereby maximizing the collection of solar energy. Aiming at the study of improving the utilization rate of solar energy, a grating-based sun tracking sensor is designed. [0003] There are many ways to track solar energy at home and abroad, mainly in the following two ways: photoelect...

Problems solved by technology

The disadvantages of these methods are: low conversion efficiency, weak tracking adaptability, low tracking accuracy

[0007] However, due to the low measurement accuracy of solar motion displacement, the efficiency of the entire solar tracking power generation system is low. In order to achieve high-precision automatic tracking of the sun without manual supervision and improve the efficiency of solar energy utilization, a solar tracking sensor based on gratings is proposed.
