Title (EN) METHOD AND APPARATUS FOR VIBROACOUSTIC MODULATION CRACK DETECTION AND CHARACTERIZATION OF CONDUITS
(FR) PROCÉDÉ ET APPAREIL DE DÉTECTION DE FISSURE ET DE CARACTÉRISATION DE CONDUITES PAR MODULATION VIBROACOUSTIQUE
Abstract:
(EN) A crack detecting system operable to detect cracks along a conduit or structure includes a tool movable along a conduit or structure and having at least one sensing device for sensing cracks in a wall of the conduit or structure. A processor is operable to process an output of the at least one sensing device. Responsive to processing of the output by the processor, the processor is operable to determine the presence of cracks at the wall of the conduit or structure. The at least one sensing device includes or provides a vibroacoustic modulation technique.
(FR) La présente invention concerne un système de détection de fissure opérationnel pour détecter des fissures le long d’une conduite ou d’une structure qui comprend un outil mobile le long d’une conduite ou d’une structure et comportant au moins un dispositif de détection pour détecter les fissures dans une paroi de la conduite ou de la structure. Un processeur est opérationnel pour traiter une sortie de l’au moins un dispositif de détection. En réponse au traitement de la sortie par le processeur, le processeur est opérationnel pour déterminer la présence de fissures au niveau de la paroi de la conduite ou de la structure. L’au moins un dispositif de détection comprend ou fournit une technique de modulation vibroacoustique.
