Abstract

La présente invention concerne un procédé de communication entre d'une part au moins deux dispositifs capteurs/actuateurs synchronisés et d'autre part au moins un senseur, les dispositifs et le senseur étant disposés dans une structure, le procédé comprenant : - une phase d'apprentissage (100) dans laquelle o on excite la structure à la position du senseur en générant une onde vibratoire dite « primaire » apte à se propager dans la structure, o on enregistre au niveau des capteurs/actuateurs des signaux vibratoires contenant l'onde vibratoire primaire, chaque signal vibratoire étant associé à un capteur/actuateur respectif, - une phase de restitution (200) dans laquelle o on retourne temporellement les signaux vibratoires enregistrés pour obtenir des signaux vibratoires en temps retourné, o on génère au niveau de chaque capteur/actuateur une onde vibratoire dite « secondaire » correspondant au signal vibratoire associé audit capteur/actuateur.The present invention relates to a method of communication between on the one hand at least two synchronized sensor / actuator devices and on the other hand at least one sensor, the devices and the sensor being arranged in a structure, the method comprising: a phase of 'learning (100) in which o the structure is excited at the position of the sensor by generating a so-called "primary" vibratory wave capable of propagating in the structure, o vibratory signals containing the wave are recorded at the level of the sensors / actuators primary vibratory signal, each vibratory signal being associated with a respective sensor / actuator, - a restitution phase (200) in which o the recorded vibration signals are temporally returned to obtain vibratory signals in returned time, o one generates at each sensor / actuator a so-called “secondary” vibratory wave corresponding to the vibratory signal associated with said sensor / actuator.
