How to realize intelligent sunshade control system

Modern buildings are increasingly focusing on energy saving, permeability and environmental comfort. Shading is an effective way to save energy in buildings. Through good shading design, energy can be enriched while enriching the light distribution in the room. It can also enrich the architectural modeling and facade effects. . Intelligent sunshades need control systems to improve and control. Here we introduce smart sunshade control systems.

Smart Sunshade Control System Introduction

As an intelligent sunshading system that is indispensable to building intelligent systems, with the continuous advancement of technology and the popularity of building intelligence, building sunshades will have more complete intelligent control systems. It is believed that more and more buildings will adopt intelligent sunshading systems. , And in the design phase should be integrated to capture, intelligent perspective to achieve the best shade. Intelligent sunshade system mainly rely on its intelligent control system to achieve energy-saving purposes.

How to realize intelligent sunshade control system

The smart sunshade control system now used most is based on the LONWORKS control network technology and can achieve the following functions: The system calculates the solar elevation angle and azimuth angle for different seasons, dates, different time periods and different orientations based on local meteorological data and sunshine analysis results. . Then, the intelligent controller controls the veil turning angles in different directions according to the set period of time. The multi-azimuth sunlight sensor installed on the roof detects sunny or cloudy days. On cloudy days, the system controls the horizontal opening of the louver; on sunny days, it is executed according to the sunlight automatic tracking mode. At the same time, the occluding model is created based on the building itself and the surrounding buildings, and the daily shadow change of the reference point is calculated and stored in the motor controller. , and then run automatically according to the result.

Intelligent sunshade control system parameters

In the shading control system, some software and hardware parameters need to be set, mainly including:

1, switch settings

The short operation of the control switch (

2, blinds track setting

Venetian blinds tracking must be activated through automatic posting. The calculation of the solar azimuth should take into account the elevation and azimuth angles. This ensures adequate shading (such as display workstations) while also maximizing the use of daylight in the interior, thereby reducing the need for artificial light. The maximum possible discrimination of the louver angle depends on the overall mechanical system of the baffle used. If the upper limit of the adjustable "Sun" image is exceeded and the "ON" delay is exceeded (see above), then the slat blinds must be tracked until the sun's position, based on the orientation table stored in the motor control unit. With the aid of the current elevation angle and azimuth angle of the sun, the orientation and inclination (if applicable) can be selected step by step from the orientation table stored in the motor control unit at an interval. These solar angles are calculated within the sensor unit (LONSE) and can be used for LONWORKS network nodes. The actuator calculates the projection angle of the daily beam on the plane of the house based on the direction of the plane of the house and the current time.
