Title (EN) DEVICE FOR BETTER TRANSMISSION THROUGH THE RAIL BETWEEN A RAILWAY TRACK AND A GROUP OF VEHICLES RUNNING ON THIS TRACK
(FR) DISPOSITIF DE TRANSMISSION D"INFORMATIONS PAR LES RAILS ENTRE UNE VOIE DE CIRCULATION FERROVIAIRE ET UN ENSEMBLE DE VEHICULES CIRCULANT SUR CETTE VOIE
Abstract: front page image
(EN)A better transmitting device is disclosed where the propagation zones of the information signals are independent of the block sections of the system. A generator (11) of alternating signals modulated in (12) by the signals (13) to be transmitted is coupled to the lines of rail (1 and 2) by induction, by means of a spiral (6) downstream of the zone. Each information transmitting zone is defined upstream and downstream by resonant circuits (4 and 5) tuned on the carrier frequency of the transmitted signals. This frequency is selected in order to avoid any interaction between the track circuits and the information transmitting device. Application to railway traffic.
(FR)Dispositif de transmission d"informations dont les zones de propagation des signaux d"information sont independantes des sections du systeme de cantonnement. Un generateur (11) de signaux alternatifs modules en (12) par les signaux (13) a transmettre est couple aux files de rails (1) et (2) par induction, au moyen d"une spire (6) en aval de la zone. Chaque zone de transmission d"informations est delimitee en amont et en aval par des circuits resonnant (4 et5) accordes sur la frequence porteuse des signaux emis. Cette frequence est choisie de maniere a eviter toute interaction entre les circuits de voie et le dispositif de transmission d"informations. Application a la circulation ferroviaire.
