Abstract

L'un des problèmes fondamentaux du système de block automatique à courants codés (Bacc) actuellement utilisé sur environ 5 000 miles du réseau de RFI (Rete Ferroviaria Italiana) est la nécessité d'utiliser des joints isolés pour séparer les diverses sections de voie, ce qui fait partie des causes de rupture des voies les plus fréquentes. L'idée de base de cette invention est de séparer les différentes sections de la ligne non pas par isolation galvanique des rails, mais par des courts-circuits entre les rails, ce qui permet une plus grande continuité le long des rails et de supprimer ainsi complètement les joints isolés fragiles. Les court-circuits isolent un circuit électrique qui "bouge" en fonction du mouvement du train, ce qui fait qu'il y a toujours devant le train un générateur pouvant générer le courant codé qui est lu à bord en fonction d'un protocole de chemin de fer spécifique. La présence de matériel roulant peut être détectée par des capteurs de courant spéciaux placés à des endroits spécifiques le long du rail. Les détecteurs détectent l'arrivée du train au moyen des courts-circuits générés par les essieux du train, éliminant, au niveau des capteurs le courant imprimé par les générateurs. La transmission de signaux à bord du train reste inchangée par rapport aux systèmes précédents, de telle sorte qu'aucune modification du sous-système à bord n'est nécessaire. Le niveau d'intégrité exigé de la sécurité est facilement atteint car le système a la possibilité de relire ce qui est transmis au train. Il est possible d'installer le système proposé dans des voies spécifiques de la ligne. La coexistence sur la même ligne de voies équipées de manière classique (avec des joints isolés) et de voies munies de ce nouveau système permet une transition progressive d'un système à l'autre. Ce système permet également l'observation des paramètres électriques des rails, déclenchant des alarmes en cas de types de ruptures ou d'endommagements spécifiques des rails.
