A WINDOW SHADING CONTROL SYSTEM AND METHOD THEREOF BASED ON DECOMPOSED DIRECT AND DIFFUSE SOLAR RADIATIONS

摘要

A window shading control system (100) includes a sensor (110) configured to produce a global radiation measurement for e ach direction of at least four directions wherein each global radiation measurement is a combined direct and diffuse component of at least one of illuminance and irradiance; a processor (120) connected to the sensor and configured to compute a discrete direct component and a diffuse component for global radiation measurement; and a control circuit (130) connected to the processor and configured to control a window shading system (150) based on the discrete direct component and the diffuse component computed for at least one global radiation measurement.
