CA 2698153

Methods and devices are provided for monitoring the condition of the running gear of a railcar utilizing acoustic/motion/vibration sensors mounted on the railcar while the railcar is underway. For some embodiments, utilizing this sensor data, defects in the running gear may be detected, and this information may be used to alert an operator to the defective condition. Operated in conjunction with a GPS or similar location detection device, a plurality of sensors mounted on a plurality of railcars may also be used to identify damaged or worn sections of track.

L'invention concerne des procédés et des dispositifs pour surveiller l'état de l'organe de roulement d'un véhicule ferroviaire à l'aide de capteurs acoustiques/de mouvement/de vibration embarqués sur le véhicule ferroviaire alors que le véhicule ferroviaire est en marche. Dans certains modes de réalisation, l'utilisation des données de capteurs permet de détecter la défaillance d'un train de roulement et cette information permet de signaler l'état défectueux à un opérateur. Actionnés conjointement avec un GPS ou un dispositif de détection de position analogue, plusieurs capteurs montés sur plusieurs autorails permettent également d'identifier des sections endommagées ou usées de la voie.
