Abstract

L'invention concerne un procédé, un serveur et un système de planification de transport ferroviaire. Le procédé de planification de transport ferroviaire de la présente invention consiste à : recevoir des informations de train et des informations de station de base envoyées par une station montée sur un véhicule, et mettre à jour ces informations par rapport à un système de planification de secours ; détecter un état de fonctionnement d'un système de planification central en temps réel, et déterminer si le système de planification central est dans un état normal ; lorsque le système de planification central est dans un état anormal, planifier le transport ferroviaire à l'aide du système de planification de secours, le système de planification de secours et le système de planification central fonctionnant indépendamment en parallèle. Au moyen du procédé, la présente invention permet de réaliser la planification sans fil d'un train circulant sur le réseau lorsqu'un centre de commande d'un système de planification central est totalement en panne, ce qui permet de garantir au maximum la sécurité de fonctionnement du transport ferroviaire.
