Title: Systeme de signalisation ferroviaire a controleurs redondants
Inventor: LOSTUN VIRGIL
IPC: B61L27/00
Filed: 2012-06-21
Abstract: L'invention concerne un système de signalisation ferroviaire permettant de contrôler une charge. Selon les principes de la présente invention, le système comprend un premier contrôleur autonome et un second contrôleur autonome qui est redondant avec le premier contrôleur autonome, chaque contrôleur pouvant être connecté à la charge de sorte qu'il n'y ait pas de point de panne unique. Les premier et second contrôleurs peuvent fonctionner soit en mode en ligne, les deux sorties de puissance fournissant une puissance à la charge, soit en mode hors ligne, une seule sortie de puissance ne fournissant pas de puissance à la charge. Les contrôleurs en ligne surveillent le courant qui la traverse. Quand les deux contrôleurs sont en ligne, le courant entre les deux contrôleurs est déséquilibré jusqu'à une limite seuil, si la limite seuil est dépassée par un contrôleur, ce contrôleur passe hors ligne, et si le premier contrôleur est hors ligne et que le second contrôleur est en ligne, le second contrôleur surveille les tensions de sortie du contrôleur en ligne pour s'assurer que les tensions de sortie sont à zéro.
