Abstract

Système de transmission de données par circuit de voie permettant d'obtenir un grand débit d'information et d'accroître la sécurité du trafic ferroviaire. Il comprend entre un émetteur disposé au sol et un récepteur embarqué à bord du véhicule ferroviaire recevant les informations par la voie ferrée court-circuitée par les essieux du véhicule une liaison modulée en déviation de fréquence. Applications : contrôle de sécurité du trafic ferroviaire.Track circuit data transmission system providing a high flow of information and increasing the safety of rail traffic. It comprises a link modulated in frequency deviation between a transmitter placed on the ground and a receiver on board the railway vehicle receiving the information via the railway short-circuited by the axles of the vehicle. Applications: safety control of rail traffic.
