Site-adaptive sunshade adjustment system

Abstract

The invention discloses a site-adaptive sun-shading adjusting system, and relates to the technical field of automatic sun shading. A photoelectric sensor capable of sensing sunlight irradiation is arranged on a table that needs sun shading, a controller senses sunlight irradiation through the photoelectric sensor, thereby judging a position of a shadow area caused by a sunshade, specifically a direction coordinate that guides the sunshade to move is formed through the photoelectric sensor, the sunshade moves according to a 10cm*10cm grid, and realizes sun shading again through automatic movement adjustment, and the defects that in a sunshade movement process a movement direction is inaccurate, or calculation and adjustment of a movement angle and direction movement are complicated, and coordinate repositioning is difficult are reduced. According to the site-adaptive sun-shading adjusting system, through reverse adjustment, required electronic components are reduced, the system structure is optimized, implementation is easier in effect compared with a method of actively following sunlight, and an algorithm is simpler.

Description

Technical field [0001] The invention relates to the technical field of automatic sun shading, in particular to a site adaptive sun shading adjustment system. Background technique [0002] Sun umbrellas are also called sun umbrellas. They are mainly used to protect against direct sunlight. They are used in summer and can effectively isolate the skin from UV damage. Umbrellas are generally placed outdoors for use and fixed by a heavier mounting seat. However, the existing outdoor umbrellas have a large umbrella surface, that is, the umbrellas are relatively heavy and often do not move after being supported, but in the open outdoors On open occasions such as the beach or the beach, the sunshading effect will change with the seasons, and it will obviously change with the position of the sun during the day. This requires frequent movement of the parasol, or the sunshade effect cannot be achieved. There is a need for an automatically adjustable sunshade, which adjusts the position acc...

AI Technical Summary

Problems solved by technology

[0003] The object of the invention of the present invention is to address the above problems, to provide a site-adaptive sunshade adjustment system, which has the function of automatic movement adjustment, to ensure the sunshade or shade effect of people under the sunshade umbrella; by automatically judging whether the shadow position formed by the sunshade umbrella is covered The area that needs shading is then automatically moved to ensure that the shading position will not change greatly with the position of the sun, thereby ensuring the shading effect and providing a multifunctional parasol; solving the problem that cannot be automatically adjusted in the prior art
