Abstract

La présente invention concerne un système de commande de réseau ethernet pour train, un procédé de configuration automatique associé ainsi qu'un véhicule ferroviaire. Le système consiste en un module de commutation et un module de terminal. Le module de commutation comprend de multiples appareils de commutation, et les appareils de commutation comprennent des fichiers de configuration pré-configurés. Après que les appareils de commutation aient été attribués à des wagons, des informations de configuration correspondant à des informations d'adresse peuvent être déterminées à partir des fichiers de configuration selon les informations d'adresse entrées, et une opération de configuration est effectuée en fonction des informations de configuration de façon à obtenir une configuration automatique des appareils de commutation. Lorsqu'un appareil de terminal est connecté à un port des appareils de commutation, les appareils de commutation acquièrent des informations d'authentification d'identité de l'appareil de terminal, et ils configurent automatiquement l'appareil de terminal. Pendant le processus de configuration, si les informations d'authentification d'identité de l'appareil de terminal ne sont pas authentifiées, le port connecté à celui-ci est fermé, ce qui permet d'empêcher l'accès à une interface par un appareil externe inconnu ou par un appareil de terminal d'un mauvais type. Pendant la totalité du processus de configuration, des opérations manuelles destinées à déterminer ou à enregistrer des informations de configuration ne sont pas requises, facilitant ainsi la réduction des coûts de maintenance manuelle, améliorant l'efficacité de maintenance et réduisant la possibilité que des erreurs ne soient commises.
