A WIRELESS SENSOR NETWORK FOR DAMAGE DETECTION AND HEALTH MONITORING OF CABLES
Un réseau de capteur sans-fil pour la détection des défauts des câbles
Résumé
Acoustic emission emerges as one of the reliable methods for cable health monitoring. Practical implementation involves numerous acoustic sensors to be placed along cables, as well as a supervising system. The Public Works Laboratory has developed such a platform. One version has been produced, and actually equips several bridges (Tancarville bridge, Iseron bridge, Aquitaine bridge,...). The system provided reliable results and was able to warn on-time bridge operators in case of critical health state. This article aims at presenting recent progresses towards better reliability of break detection by means of DSP, and increased flexibility provided by a TCP/IP-WIFI wireless implementation.
