Abstract

A.PROCEDE POUR CODER DES CIRCUITS DE VOIE ET PERMETTRE NOTAMMENT LA TRANSMISSION D'INFORMATIONS A UN VEHICULE CIRCULANT SUR UNE VOIE DE CHEMIN DE FER DIVISEE EN UNE SUCCESSION DE CANTONS EQUIPES CHACUN D'UN CIRCUIT DE VOIE, DANS LEQUEL CHACUNE DES FREQUENCES PORTEUSES D'EXCITATION DES CIRCUITS DE VOIE EST MODULEE EN FREQUENCE PAR UN CERTAIN NOMBRE DE FREQUENCES DE MODULATION REPRESENTANT CHACUNE UNE INFORMATION A TRANSMETTRE. B.CE PROCEDE CONSISTE A COMPARER LA FREQUENCE DE MODULATION, OBTENUE PAR DEMODULATION DE LA FREQUENCE PORTEUSE MODULEE, AVEC UNE AUTRE SOURCE DE MODULATION, AFIN DE CONTROLER QUE LADITE FREQUENCE DE MODULATION EST BIEN CORRECTE, ET A N'AUTORISER L'EMISSION DE LA FREQUENCE PORTEUSE MODULEE DANS LE CIRCUIT DE VOIE CORRESPONDANT QUE LORSQUE CE CONTROLE EST POSITIF. C.TRAINS DE CHEMIN DE FER A GRANDE VITESSE.
