Abstract

Le numéro d'identification d'un objet en mouvement s'inscrit automatiquement sur un afficheur placé dans cet objet en mouvement et une information relative à cet objet s'inscrit sur cet afficheur. Cette invention a trait au domaine des transports, notamment aux réseaux ferrés et terrestres. Lorsqu'un afficheur portable est installé dans un convoi de chemin de fer, le conducteur n'est pas obligé d'entrer un numéro d'administration tel que le numéro de convoi. Par contre l'objet en mouvement (convoi) est automatiquement corrélé à un terminal embarqué ou à un terminal portable placé dans ce convoi et le numéro d'administration de l'objet en mouvement est entré dans le terminal embarqué ou dans le terminal portable, ce qui soulage le conducteur dans son travail. Le système prenant en charge plusieurs objets en mouvement comporte une unité de stockage de numéro d'identification stockant les numéros d'identification aux fins de l'identification de chaque objet en mouvement, une unité de détection de position d'objet en mouvement aux fins de la détection de chaque objet en mouvement et une unité de compilation - notification extrayant la position de chaque objet en mouvement de l'unité de détection de position et indiquant qu'un objet en mouvement s'approche d'un autre objet en mouvement, le repérage s'effectuant grâce au numéro d'identification d'objet en mouvement présent dans l'unité de stockage de numéros d'identification.
