High precision sun azimuth tracking device based on psd

Abstract

The invention relates to the technical field of solar energy source, and particularly relates to a high-accuracy sun azimuth tracking device based on PSD (Power Spectral Density). The technical scheme is as follows: the high-accuracy sun azimuth tracking device based on PSD is a sensor. The sensor comprises a shell, a base, a lens, a lens pressing sheet, a semiconductor heating block, a heat insulation part and a photocell, wherein the shell is internally provided with a PSD and a PSD subassembly; the upper wall of the shell is provided with a hole in a cone frustum shape; the outer side of the upper wall is provided with the lens pressing sheet; the lens is arranged in the lens pressing sheet in a pressing way; the lens is arranged by just facing to the hole in the cone frustum shape; four photosensitive devices are uniformly distributed on the intermediate part of the outer side of the shell; the PSD subassembly is arranged in the shell; the outer side of the PSD subassembly is provided with the heat insulation part fixedly connected to the shell; and the lower part of a support plate inside the PDS subassembly is provided with the semiconductor heating block. The high-accuracy sun azimuth tracking device based on PSD, which is disclosed by the invention, has the advantages that a very wide detection view angle of 270 degrees can be achieved, the angle measurement can not be influenced through light-intensity variation and the measurement accuracy can reach 0.001 degrees within a temperature range from -40 DEG C to 60 DEG C.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to the technical field of equipment for efficient collection and utilization of solar energy, and further relates to a high-precision solar azimuth tracking device based on PSD. Background technique [0002] The world is currently facing a resource crisis. Excessive consumption of non-renewable resources has caused great damage to the environment. Therefore, all countries are studying the method of using renewable energy. Solar energy is clean, widespread and long-lasting, and it is a high-energy renewable energy source. However, since the sunlight radiated to the ground is affected by natural conditions such as climate and latitude, it is also scattered and random, which increases the difficulty of collection and utilization. Now there are solar trackers with high precision at home and abroad, but they are expensive. In addition, some four-quadrant detection devices detect the posit...
