| 摘要 |
The invention relates to a device which detects and locates an impact (17) on a structure (11). The device comprises at least three acoustic sensors (13) so that an acoustic wave (18) emitted at any point of a measurement space (12a) can be received through direct propagation by each of the sensors (13), and comprises command and control means (15) configured to process the signals corresponding to the acoustic waves received by the acoustic sensors (13), to detect the occurrence of an impact (17), and to locate a point of the structure that is the source of an acoustic wave (18). At least one optical pointer (14) is actuated by the command and control means (15) so as to designate an impact point (17) located on the structure by illuminating (22) a corresponding site of said structure. |
