Embodiment Construction

[0053] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following detailed description will be given.

[0054] Such as figure 1 As shown, the photodiode integrated sensor consists of a black hemispherical shell with a thickness of more than 3mm and 7 photodiodes. There are 7 through holes with a diameter of 5mm on the black hemispherical shell, which are used to install photodiodes. The through holes and the diodes are tightly fitted, and the central axes of all the through holes meet at the center of the black hemispherical shell. The D5 hole is located at the apex of the hemispherical shell. In the D3-D7 holes, the angle between the axes of two adjacent holes is θ, and the angle between the axes of the two adjacent holes of D1, D5 and D2 is η. The black thick hemispherical shell and the design of the centripetal through hole can improve the detection sensitivity of the photodiode when the sunlight angle ch...

Abstract

The invention discloses a device and method for acquiring the vertical incident direction of sunshine. The method comprises the steps of collecting sun illumination signals by virtue of a photosensitive diode integrated sensor, processing the collected signals by virtue of an LM339N chip, carrying out logical operation by virtue of STC90C516RD+, and finally acquiring the vertical incident direction of the sunshine, wherein the photosensitive diode integrated sensor is produced by embedding a plurality of photosensitive diodes into a black hemisphere shell. According to the technical scheme, the vertical incident direction of the output sunshine is represented by a direction of a spatial vector gamma (-x, -y, -z) with modulus of 1. The design scheme has the beneficial effects that the cost is low, the system design is simple, and the stability is relatively strong; and by increasing the number of the photosensitive diodes embedded into the photosensitive diode integrated sensor, the requirement on the detection precision of the vertical incident direction of the sunshine can be met. According to the design scheme, a sun tracking system with changeable tracking precision can be produced.

Description

technical field [0001] The invention relates to the design field of solar trackers, in particular to a device and method for obtaining the vertical incident direction of sunlight. Background technique [0002] Since the 21st century, the use of green energy has been advocated all over the world. As the largest developing country in the world, China is also vigorously increasing the proportion of green energy use in order to reduce dependence on traditional energy and improve environmental quality. As one of the most important green energies, the use of solar energy has brought many conveniences to human beings and also played a great role in improving the environment. [0003] At present, human beings use solar energy mainly in two ways: photothermal conversion and photoelectric conversion. Among them, the technology of photothermal conversion has become mature, but the photoelectric conversion technology is still largely limited by its conversion efficiency and has not bee...
