Abstract

DISPOSICION DE SEGURIDAD PARA SUBSISTEMAS IDENTICOS DE APARATOS DE CONTROL ELECTRONICOS.UNA SERIE DE SUBSISTEMAS DE CONTROL EN PARALELO (X, Y, Z0 RECIBEN A TRAVES DE UN CAMINO DE SEÑALES (4), ESPECIFICO PARA CADA UNO O MULTIPEXADO, UNA MULTIPLICIDAD DE SEÑALES INDICADORAS DEL ESTADO DE DIVERSOS DISPOSITIVOS DE CONTROL. CADA SUBSISTEMA PROCESA UNICAMENTE LAS PALABRAS DE DATOS DE LAS SEÑALES DESTINADAS AL MISMO, Y LAS SEÑALES DE SALIDA (5, 6, 7) SE COMBINAN, PARA ALCANZAR UN MAYOR NIVEL DE SEGURIDAD, MEDIANTE BLOQUES ELECTRONICOS (8) QUE PROPORCIONAN SALIDASUNICAS CONSOLIDADAS (9). ESTA CONSOLIDACION ADMITE VERIFICACIONES DE NO COINCIDENCIA, EN OTRO BLOQUE CORRESPONDIENTE (10).DE APLICACION EN DISPOSITIVOS DE CONTROL DE TRAFICO FERROVIARIO.
