Two-dimensional laser scanning solar angle detection device

Abstract

The invention discloses a two-dimensional laser scanning solar angle detection device, which comprises a flat cylinder with a hollow structure and a flat cylinder structure, wherein the flat cylinder comprises a left half cylinder and a right half cylinder which are symmetrical to each other; the semicircular arc-shaped side wall of the left half cylinder is provided with a plurality of leak holes; the semicircular arc-shaped side wall of the right half cylinder is provided with a plurality of through holes; the flat cylinder structure comprises a plurality of hollow cylindrical tubes; the outer end of each hollow cylindrical tube is provided with an optical sensor; each through hole is communicated and fixedly arranged with the inner end of one hollow cylindrical tube; a plurality of leak holes and a plurality of through holes are formed symmetrically; and the central connecting line of a pair of symmetrical leak hole and through hole is coincided with the middle axis of the hollow cylindrical tube arranged on the through hole, and passes through the geometric center of the flat cylinder. The solar angle detection device has a simple structure; and two-dimensional data are measured by using two same devices of the same structure, so that an obtained measuring result has relatively high reliability and mutual reference.

Description

technical field [0001] The invention relates to a sun angle sensing device, in particular to a two-dimensional radar scanning type sun angle detection device. Background technique [0002] The existing sun tracking sensors have the following types of signal collection: one is to use a photosensitive chip as the core device to receive the illuminance of sunlight, and use the method of quadrant analysis to calculate the direction and angle information of the sun by computer. Then there is the image method, that is, according to the position of the light spot image formed by the sun on the image receiving screen, the direction angle information of the sun is reversely calculated, and there are other types of sensors that are basically the same as the above two. [0003] The above sensors are generally only suitable for low-precision use environments, and the obtained data is not directly measured, and the required data can only be obtained after multiple calculations. In the r...

Problems solved by technology

In the relevant calculation process, the greater error caused by the cumulative effect of calculation errors, coupled with the unreliability caused by multiple calculations, greatly affects the stability of the system. In addition, the transparency of the atmosphere also has a certain impact on the measurement.
