| 摘要 |
<p>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 pickup, the devices and the pickup being disposed in a structure, the method comprising: - a learning phase (100) in which: the structure is excited at the position of the pickup by generating a so-called "primary" vibratory wave able to propagate in the structure; vibratory signals containing the primary vibratory wave are recorded at the level of the sensors/actuators, each vibratory signal being associated with a respective sensor/actuator; - a restitution phase (200) in which: the vibratory signals recorded are temporally reversed so as to obtain reversed-time vibratory signals; at the level of each sensor/actuator is generated a so-called "secondary" vibratory wave corresponding to the vibratory signal associated with said sensor/actuator.</p> |
