AI Technical Summary
Existing load control systems are susceptible to glare detection by reflections from small surfaces on the exterior of buildings and noise interference, leading to unnecessary or incorrect control of motorized window sills.
Visible light sensors are used to process images to determine the location and intensity of glare sources. By processing the pixels and resolution of the image, glare conditions are identified, and the operation of motorized window curtains is controlled to prevent glare from affecting indoor occupants. The sensor and system controller can process the pixels of the image to determine whether glare conditions exist, and control the position of the curtains based on the glare condition threshold and the representative brightness of the pixel group.
It effectively identifies and prevents glare, reduces unnecessary control of electric window sills, improves the accuracy and efficiency of the system, and avoids noise interference.
