Definitions

• the invention relates to the field of sun protection and in particular to the protection thereof against the effects of wind. It relates in particular to initialization methods for controlling an installation comprising at least one motorized device having a movable closure, concealment or sun protection element, each motorized device being provided with a sensor for measuring the effects wind on its moving element. It also relates to methods for controlling an installation initialized according to the preceding method and to installations for implementing these methods.
• gusts of wind can seriously damage the structure of a screen or the supporting structure and / or cause significant damage.
• Various wind sensors of several types such as anemometers, accelerometers, torque or rotation detectors of the winding tube, are known.
• the accelerometers and the detectors of torque or rotation of the winding tube integrated into the structure of the blind are the most representative of the forces due to the wind, undergone by the screen. Indeed, in the case of anemometers for example, it is only possible to measure a wind speed, in a determined zone. The anemometer is often placed on a building facade or on a roof, it is sometimes common for a set of sunscreens. As a result, the measured values are not always representative of the forces exerted on the screen. On the other hand, the major drawback of the sensors directly integrated into the structure of the screen is the inability to provide information on the state of the wind once the screen is retracted.
