Description

Intelligent sunshade dimming system and its control method

technical field

The invention relates to the field of building lighting and shading, in particular to an intelligent sunshade and light adjustment system and a control method thereof.

Background technique

Building shading is an effective way to save energy in buildings. Good shading design can not only save energy, but also enrich the indoor light distribution, and also enrich the architectural shape and facade effect. As an indispensable intelligent shading system for building intelligent systems, with the continuous advancement of technology and the popularization of building intelligence, building shading will have a more complete intelligent control system. It is believed that more and more buildings will adopt intelligent shading systems , and should be integrated and absorbed at the design stage, and the intelligent angle makes the sunshade achieve the best effect.

The intelligent shading system mainly relies on its intelligent control system to achieve the purpose of energy saving. Usually, the system calculates the sun elevation and azimuth angles for different seasons, dates, time periods and orientations based on local meteorological data and sunshine analysis results. Or use the sun tracking system to get the elevation and azimuth of the sun. Combined with the orientation of the building, the intelligent controller controls the flip angle of the louvers in different orientations according to the set time period.

This method requires too many input parameters, which makes debugging troublesome. Moreover, the problem that the opening angle of the louvers should be increased when the sun brightness decreases in cloudy days or special weather conditions is not considered. Moreover, factors such as the sun's rays being blocked and refracted lead to the fact that the position where the sun should exist is not the brightest place in the sky.

The present invention directly utilizes the omni-directional rotation of the venetian blind on the miniature model to find out the angle corresponding to the architectural venetian blind under the set light intensity, without considering many external factors such as sun position, weather and building orientation.
