Abstract

L’invention concerne un procédé de surveillance de l’état physique d’un élément longitudinal (10), caractérisé en ce qu’il comprend :- une étape de détection des ondes mécaniques se déplaçant le long de l’élément longitudinal (10) au moyen d’un réseau (14) de capteurs d’ondes mécaniques placés le long et au contact de l’élément longitudinal, ledit réseau (14) comprenant au moins une première paire (A) de capteurs (1,2) positionnés chacun à une extrémité d’une première portion (10a) de l’élément longitudinal (10), et- une étape de traitement des signaux issus des capteurs (1,2) dudit réseau (12) de capteurs, ladite étape de traitement comportant la détermination d’au moins un premier signal résultant d’une première corrélation de signaux délivrés par les capteurs (1,2) de la première paire (A) de capteurs sur une première période temporelle prédéterminée.
