Abstract

Un dispositivo para proteger las comunicaciones de datos en un sistema de control automático y contínuo de trenes, caracterizado porque los bucles del conductor de vía (LS) o de los dos conductores (EL) de los bucles del conductor de vía (LS) están terminados por resistencia controladas automáticamente (R1, R2) cuyos sistemas de control de bucle-cerrado (RS) utilizan como variable de mando la corriente o la diferencia de potencial existente entre dos puntos (P1, P2) de un conductor (EL) como resultados de la aparición de una onda estacionaria.
