Sunlight signal acquiring devices in high-precision tracking system

Abstract

The invention relates to sunlight signal acquiring devices in a high-precision tracking system. Each sunlight signal acquiring device comprises a substrate which is arranged on a sunlight receiving plane of a condenser and is provided with an internal-thread connecting base. The sunlight signal acquiring devices which are respectively formed by a group of photoelectric sensors are respectively arranged inside and outside the internal-thread connecting base on the substrate; a planoconvex lens is fixed by a fixing nut by connecting the upper end of a thread connecting tube, and the fixing nut, the thread connecting tube and the planoconvex lens are integrated into a whole body; and the lower end of the thread connecting tube is connected with the internal-thread connecting base. Due to the position distribution and the combination of the two groups of photoelectric sensors, the photoelectric sensors can be rough and fine adjusted after treating the acquired signal. Due to the adoption of the method of focusing and detecting the sunlight, the problem that the photoelectric sensors have low detection sensitivity if the solar radiation intensity is very weak is solved. Due to the adoption of the method of reducing the light intercepting areas of the photoelectric sensors, the problem that the photoelectric sensors have low detection sensitivity when the photoelectric characteristic of the photoelectric sensors affects the saturated zone if the solar radiation intensity is very strong is solved. The sunlight signal acquiring devices can supply correct signals to a post-processing circuit.

Description

technical field [0001] The invention relates to a sunlight signal collection device in a solar tracking system, in particular to a sunlight signal collection device in high-precision tracking. Background technique [0002] Due to the wide application of solar energy in photovoltaic power generation, photothermal power generation and daily life after concentrating, countries all over the world have invested a lot of manpower and material resources in this field for research, but the common feature of solar concentrators is that they must be equipped with two Dimension's high-precision sunlight automatic tracking system, and the accurate real-time all-weather sunlight signal collector that obtains high-precision signals is an essential and important part of the system. [0003] Although countries all over the world have invested a lot of manpower and material resources in researching this, but so far except for the low temperature section represented by solar water heaters, th...
