Abstract

L'invention concerne un système de rails et un procédé pour faire fonctionner un système de rails au moyen d'une pièce mobile guidée sur rails et d'une commande centrale. La pièce mobile présente un moyen destiné à détecter la position de la pièce mobile, la pièce mobile présentant un premier entraînement, en particulier un entraînement par traction, la pièce mobile présentant en moyen de détection de courant, la pièce mobile présentant un calculateur destiné à évaluer la variation de la valeur du courant détectée entre une première position et une deuxième position. Le calculateur est réalisé sous la forme d'un moyen adapté pour évaluer la variation de la valeur du courant, par le fait que des tuples de valeurs sont déterminés en tant qu'évaluation par le calculateur, lesquels présentent chacun au moins une information de position et une valeur déterminée à partir de la variation de la valeur de courant. Le calculateur est relié à la commande centrale au moyen d'un canal de transfert de données pour la transmission des tuples de valeurs, la commande centrale étant conçue pour surveiller de manière adaptée les tuples de valeurs, et surveillant la valeur respective déterminée à partir de la variation respective du courant à la recherche d'un dépassement d'un niveau admissible d'écart par rapport à une valeur prédéfinie, en particulier une valeur théorique.
