Abstract
Système et procédé servant à empêcher des collisions entre des véhicules, tels que des trains, ce qui consiste à échanger des données concernant la distance de ces trains sur les voies. L'utilisation d'une base de données (550) de distance située à bord du train, permet au système d'acquérir une indication de la distance entre des trains non basée sur la visibilité optique mais sur la distance sur la voie. L'invention concerne, de plus, un système et un procédé servant à déterminer avec précision l'emplacement de trains sans utiliser de réseau d'indicateurs latéraux. Ce système met en application un gyrophare (530), un tachymètre (520) et un dispositif (510) de détermination de position satellite, ainsi qu'une base de données (550) de distance, de façon à effectuer des évaluations continues extrêmement précises d'erreurs de mesure et de position sur les voies.
