A building external sunshade control system and control method

Abstract

The invention discloses a building exterior sunshading control system and method. The building exterior sunshading control system comprises a PLC and a plurality of temperature and luminance sensors. The temperature and luminance sensors are arranged on a plurality of sunshading units of a building correspondingly. Each sunshading unit comprises a drive device which drives a foldable aluminium alloy frame to be opened, a limiting device used for locking the foldable aluminium alloy frame, a self-locking device and an electric motor used for driving a rotary shutter device to rotate. The PLC, the temperature and luminance sensors, the limiting devices, the self-locking devices and the electric motors are in wired or wireless connection. The building exterior sunshading control system can meet different requirements for energy-saving and indoor lighting of buildings simultaneously, has various 'expression' changes, and enriches the vertical area effect of the buildings.

Description

technical field [0001] The invention belongs to the field of architectural design, and in particular relates to a building external sunshade control system and a control method. Background technique [0002] In today's world, energy conservation has become the theme of the times. my country's building energy consumption accounts for more than 27.8% of the total energy consumption of the whole society. As the weakest link in energy conservation in the building envelope, external windows rank first in energy consumption. Therefore, building shading has become a hot issue in the field of building energy conservation. Most of the existing external sunshade products are fixed structures or manual adjustments. Although partial or complete sunshade can be realized, the sunshade components cannot be adjusted according to the change of the sun altitude angle and the needs of users, so as to meet the sunshade requirements and meet the requirements of the sunshade. Improve the effect ...

Problems solved by technology

Most of the existing external sunshade products are fixed structures or manual adjustments. Although partial or complete sunshade can be realized, the sunshade components cannot be adjusted according to the change of the sun altitude angle and the needs of users, so as to meet the sunshade requirements and meet the requirements of the sunshade. Improve the effect of indoor light environment

In addition, the usual building external sunshade not only does not coordinate with the architectural shape, it cannot be an effective means of architectural decoration design, and it is also easy to cause the obstruction of the line of sight
