ACOUSTIC SYSTEM AND METHOD FOR THE TRACTION/BRAKING CONTROL OF A TRAIN

摘要

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).
