Abstract

L'invention concerne un procédé, un appareil et un dispositif d'évaluation d'état et d'avertissement précoce de défaillance (301) pour un système de traction de train, et un support de stockage lisible par ordinateur (330). Le procédé consiste à : recevoir des données d'opération de train envoyées par un système de traction évalué (s100) ; associer des informations d'état de système de traction de différents wagons et différentes trames du même train, et effectuer une analyse d'écart sur les données d'opération selon une règle prédéfinie (s110) ; effectuer une évaluation d'état en fonction d'un résultat de l'analyse d'écart (s120) ; renvoyer un résultat de l'évaluation d'état au système de traction (s130) ; et si le résultat de l'évaluation d'état est un état d'avertissement précoce prédéfini, afficher des informations d'avertissement précoce de défaillance correspondant au résultat au moyen d'un appareil d'affichage (s140). Le procédé d'alerte précoce peut réaliser de manière complète, simple et pratique une évaluation d'état sur un système de traction de train et peut également fournir un rappel d'avertissement précoce avant qu'une défaillance ne se produise, fournissant ainsi un support efficace pour la garantie de la sécurité et la maintenance du système d'un train.
