Title (EN) ACOUSTIC SYSTEM AND METHOD FOR THE TRACTION/BRAKING CONTROL OF A TRAIN
(FR) SYSTÈME ACOUSTIQUE ET PROCÉDÉ DE COMMANDE DE TRACTION/FREINAGE D'UN TRAIN
Abstract:
(EN) An acoustic traction/braking control system (1) is described, including a modulator device (303) associated with a master vehicle (ML), which receives a traction or braking request signal (302) and generates an electrical signal (308) which is transformed into an acoustic signal (309) to be transmitted in the brake pipe (301); the frequency of the acoustic signal (309) is adjusted according to the amplitude of the traction or braking request signal (302), according to a trans-characteristic function; - a transducer device (305), associated with a slave vehicle (SL), which detects the acoustic signal (309) and converts the instantaneous amplitude value thereof into an electrical signal (310) the frequency value of which is adjusted according to the frequency of the acoustic signal (309); - a frequency demodulator (306) associated with a slave vehicle (SL), which generates a traction or braking management signal (307) the amplitude of which is regulated according to the frequency of the electrical signal (310) and transmitted to a traction and braking management system (311) associated with the at least one slave vehicle (SL).
(FR) L'invention concerne un système de commande de traction/freinage acoustique (1), comprenant un dispositif modulateur (303) associé à un véhicule maître (ML), qui reçoit un signal de demande de traction ou de freinage (302) et génère un signal électrique (308) qui est transformé en un signal acoustique (309) à transmettre dans la conduite de frein (301) ; la fréquence du signal acoustique (309) est réglée en fonction de l'amplitude du signal de demande de traction ou de freinage (302), en fonction d'une fonction trans-caractéristique ; - un dispositif transducteur (305), associé à un véhicule esclave (SL), qui détecte le signal acoustique (309) et convertit sa valeur d'amplitude instantanée en un signal électrique (310) dont la valeur de fréquence est réglée en fonction de la fréquence du signal acoustique (309) ; - un démodulateur de fréquence (306) associé à un véhicule esclave (SL), qui génère un signal de gestion de traction ou de freinage (307) dont l'amplitude est régulée en fonction de la fréquence du signal électrique (310) et transmise à un système de gestion de traction et de freinage (311) associé audit véhicule esclave (SL).
