Problems solved by technology

Since there is always a deviation in the calculated tracking collector data, this deviation will affect the solar tracking accuracy of the collector. The focus deviation is different due to reasons such as , base variation, etc. Due to the error in the command calculation data, the focus deviation is different in each time period of the day, and the altitude angle and azimuth angle in real-time conditions of the sun are the most important measurement data. Using sun tracking The real-time position of the sun can be obtained by tracking the position of the sun, but the sun tracker does not have the function of outputting the altitude angle and azimuth angle, so how to use the existing sun tracker to realize the measurement of the altitude angle and azimuth angle has become a practical application important question

Abstract

The invention discloses an observatory for detecting a position of the sun. The observatory comprises a sun tracker, an angle sensor, an angle sensor bracket mechanism and a tilt angle sensor. The suntracker can be adopted to track the position of the sun to obtain a real-time position of the sun; but the sun tracker does not have a function of outputting an elevation angle and an azimuth angle,so how to use an existing sun tracker to achieve measurement of the elevation angle and the azimuth angle becomes an important issue in practical application. The observatory effectively solves the problem, measures the elevation angle and the azimuth angle of a site when measuring the position of the sun by the sun tracker by a method of mounting the tilt angle sensor and the angle sensor on thesun tracker, and can detect the azimuth angle and the elevation angle of the sun constantly.

Description

Technical field [0001] The invention belongs to the field, in particular to a weather station for detecting the position of the sun. Background technique [0002] The solar tracker is a power device that keeps the solar panel or solar energy absorbing device facing the sun at all times, and allows the sun's rays to irradiate the mechanism vertically at any time. The use of the solar tracker can significantly improve the power generation efficiency of solar photovoltaic modules. Since there is always a deviation in the calculated tracking collector data, the deviation will affect the accuracy of the solar tracking of the collector. The current situation in actual use is that each collector loop has multiple sets of solar power generation modules, and each set of modules is due to the installation accuracy The focus deviation is different due to the difference of the basic variation and other reasons. Due to the error in the instruction calculation data, the focus deviation is diff...
