A railroad traffic control system that links each locomotive (T) to a control center for communicating data and control signals. Using on-board computers (14), GPS and two-way communication hardware (20,24), rolling stock continuously communicate position, vital sign data, and other information for recording in a data base and for integration in a comprehensive computerized control system. The data base includes train schedules for real time display on train monitors (42). The current position of each train (T) is compared to its planned schedule online to provide immediate information to the dispatcher (72) to determine whether a corrective action is necessary. When a train's deviation from its planned schedule exceeds a predetermined parameter, the system automatically calculates alternative schedules for all trains in the system according to preselected operational constraints as necessary to minimize the effect of the deviation.
L'invention concerne un systme de commande du trafic ferroviaire qui relie chaque locomotive (T) ~ un centre de commande en vue de la communication de donn~es et de signaux de commande. Au moyen d'ordinateurs de bord (14), de systmes GPS et d'~quipements de communication bilat~rale (20, 24), le mat~riel roulant peut communiquer continuellement sa position, des donn~es de fonctionnement et d'autres informations qui sont ensuite enregistr~es dans une base de donn~es et int~gr~es dans un systme de commande informatis~ global. Cette base de donn~es comprend des horaires des trains qui sont affich~s en temps r~el sur des moniteurs (42) des trains. La position actuelle de chaque train (T) est compar~e en ligne avec son horaire pr~vu de fa×on ~ fournir au r~gulateur (72) des informations instantan~es permettant de d~terminer si une action corrective est n~cessaire. Lorsque l'~cart d'un train par rapport ~ son horaire pr~vu est sup~rieur ~ un paramtre pr~d~termin~, le systme calcule automatiquement des horaires de remplacement pour tous les trains du systme conform~ment ~ des contraintes op~rationnelles pr~s~lectionn~es de fa×on ~ minimiser l'effet de cet ~cart.
