Abstract

L'invention concerne un procédé d'augmentation de la disponibilité d'un système de détection de roue comprenant un capteur compteur d'essieux permettant de détecter les roues d'un véhicule ferroviaire franchissant une voie ferrée, en particulier pour une installation de signalisation de voie libre, ainsi qu'un système de détection de roue correspondant. La disponibilité est augmentée par le fait que le franchissement de la voie ferrée est détecté en plus par un deuxième capteur dont le résultat de la détection est comparé au résultat de la détection du capteur compteur d'essieux (2), une détection positive (oui + oui) sensiblement simultanée étant évaluée (7a) par le capteur compteur d'essieux et le deuxième capteur comme la détection (3) d'une roue et une détection positive n'étant évaluée (7b) par le capteur compteur d'essieux ou le deuxième capteur (oui + non ou non + oui) comme détection d'une roue que lorsqu'une détection positive de roue dans le même sens de marche est réalisée aussi bien par le capteur compteur d'essieux que par le deuxième capteur (oui + oui) pendant un intervalle de temps (5a) prédéfini.
