Abstract

Procedimiento para codificar circuitos de vía férrea, para permitir en particular la transmisión de informaciones a un vehículo que circula por una vía férrea dividida en una sucesión de cantones equipados cada uno con un circuito de vía, en el cual cada una de las frecuencias portadoras de excitación de los circuitos de vía es modulada en frecuencia por un cierto número de frecuencias de modulación que representan cada una una información a transmitir, caracterizado porque consiste en comparar la frecuencia de modulación, obtenida por desmodulación de la frecuencia portadora modulada, con otra fuente de modulación, a fin de controlar que dicha frecuencia de modulación sea correcta, y en autorizar la emisión de la frecuencia portadora modulada al circuito de vía correspondiente solamente cuando este control es positivo.
