Sunlight three-dimensional photometric system

Abstract

The invention discloses a sunlight three-dimensional photometric system. The photometric system comprises an X-axis photometric circuit, a Y-axis photometric circuit and a Z-axis photometric circuit. The X-axis photometric circuit and the Y-axis photometric circuit are respectively composed of a voltage generation circuit and a voltage frequency switching circuit. According to the sunlight three-dimensional photometric system, a three-dimensional light pulse is obtained through the voltage generation circuits, the voltage frequency switching circuits and the Z-axis photometric circuit, real-time tracking for the sun is achieved, use and installation are convenient, the operational process is simplified, and the working efficiency is improved. When the sunlight three-dimensional photometric system is applied in a solar automatic tracking system, unnecessary electric energy loss caused by driving a solar cell panel can be saved, on the basis of a test, the total generating capacity of a photovoltaic cell panel can be improved to 10%, and the cost of the photovoltaic cell panel is only 30% of a GPS.

Description

technical field [0001] The invention relates to the field of sunlight photometry, in particular to a three-dimensional sunlight photometry system. Background technique [0002] Due to the rotation of the earth, compared with a solar photovoltaic power generation system at a fixed location, the sun rises and sets every day in spring, summer, autumn and winter. The sun, the power generation efficiency will reach the best state. [0003] At present, the general solar photometry system in the world needs to calculate the angle of the sun at different times of each day of the year according to the longitude and latitude of the placement point, and store the sun position at each time of the year to PLC, single-chip microcomputer or computer In the software, it is necessary to calculate the sun position at each moment of the fixed location to track the sun and measure the maximum light. It adopts computer data theory, which requires the data and settings of the latitude and longi...
