Abstract

Procédé de surveillance d’un ouvrage d’art (100) comportant des câbles tendus (110, 120) constitués de fils, pour la surveillance des câbles par détection de rupture de fil ou par analyse vibratoire des câbles, dans lequel on dispose plusieurs modules acoustiques (150) identiques de façon répartie sur au moins une longueur d’un câble donné de l’ouvrage d’art, chacun desdits modules acoustiques comprenant un accéléromètre, une unité de traitement de données, des ports de communication réseau et une horloge interne, on connecte lesdits modules acoustiques les uns aux autres de sorte que chacun desdits modules acoustiques peut communiquer des données générées par son accéléromètre aux autres modules acoustiques, et on configure l’un desdits modules acoustiques comme module maître pour envoyer un signal de synchronisation aux autres modules acoustiques que l’on configure comme des modules esclaves, de manière à synchroniser lesdites horloges internes des modules acoustiques. Fig. 1AMethod for monitoring a structure (100) comprising tensioned cables (110, 120) made up of wires, for monitoring the cables by detection of wire breakage or by vibration analysis of the cables, in which there are several modules identical acoustic modules (150) distributed over at least one length of a given cable of the structure, each of said acoustic modules comprising an accelerometer, a data processing unit, network communication ports and an internal clock , said acoustic modules are connected to each other so that each of said acoustic modules can communicate data generated by its accelerometer to the other acoustic modules, and one of said acoustic modules is configured as a master module to send a synchronization signal to the others acoustic modules which are configured as slave modules, so as to synchronize said internal clocks of the acoustic modules.
