Automatic sun tracker and automatic sun tracking method based on imaging feedback technology

Abstract

The invention provides an automatic sun tracker based on imaging feedback technology. The device uses two plane mirrors and two rotating slides to vertically guide sunlight into the beam splitting and imaging optical paths, and after the plane mirrors change to a horizontal direction Divided into infrared light and ultraviolet-visible light by a spectroscope, in which the ultraviolet-visible light is filtered and focused to image the sun on the diaphragm, and the image of the diaphragm hole and the sun is captured by the camera to determine the center position of the sun and the diaphragm hole. The deviation of the center position is fed back to the two rotating slides to adjust the orientation of the two mirrors, so that the center of the sun and the center of the aperture hole are coincident. At the same time, the device has GPS and inertial navigation system, which can compensate the sun tracking error caused by bumps when the device is used for moving the platform. The sun tracking of the automatic sun tracker of the present invention is more stable, accurate and reliable, and can be applied to the sun tracking under multiple scenarios, such as the use of fixed points or the use of mobile platforms such as vehicle, ship and airborne.

Description

technical field [0001] The invention belongs to the field of environmental monitoring and optical remote sensing, in particular to an automatic sun tracker based on imaging feedback technology. Background technique [0002] Volatile organic compounds emitted from anthropogenic or natural sources are key precursors of atmospheric ozone pollution and fine particulate matter. Ozone generation in urban areas of my country is dominated by volatile organic compounds, while ozone in non-urban areas is dominated by nitrogen oxides. With the increasingly strict control of nitrogen oxide emissions, volatile organic compounds have become a key factor in the control of urban atmospheric ozone and fine particulate matter pollution in my country. Industrial parks are an important source of anthropogenic emissions of volatile organic compounds, which are mainly reflected in the unorganized emissions of characteristic pollutants such as alkanes and olefins. The emission of volatile organi...
