Patent ID: 8581163

Claim:
An automated control method for a solar protection screen (SCR) installation (INST) comprising retroreflecting-type slats (B 1 , B 2 , B 3 ) which can be inclined between two extreme inclinations, wherein, in the presence of direct solar radiation, the slats are inclined at a first intermediate inclination, equal to the maximum aperture inclination (AMAX) of the screen relative to a preferred direction, as long as an inclination threshold automatically controlled in relation to the height of the sun (ATH) remains less than the maximum aperture inclination, wherein the maximum aperture inclination (AMAX) of the screen relative to the preferred direction is a position of inclination of the slats in which the areas of the slats projected in the preferred direction are minimal with respect to a view, wherein the inclination threshold automatically controlled in relation to the height of the sun (ATH) is determined by application of a model of daily and seasonal variation; wherein parameters of the model of daily and seasonal variation are determined by a learning step in which an operator moves the slats so as to position them at a setting inclination, this setting inclination being the limit inclination of the slats in which the direct solar rays are reflected by the slats without affecting the other slats; and wherein the inclination threshold automatically controlled in relation to the height of the sun (ATH) is defined to be dependent on the angle of incidence (ASUN) of direct solar radiation, the definition being the limit inclination for which direct solar rays are retroreflected by the slats without affecting the other slats.
