Granted: 2016-02-12
Abstract: Dispositivo sensor y procedimiento para detectar y contar el número de ejes para la detección de trenes en vías férreas, utilizando un sistema sensor formado por dos bobinas, una transmisora (1) y otra receptora (2), y un procedimiento de detección (donde toda la electrónica está fuera del entorno de vía) de presencia/ausencia de rueda, basado en un sistema redundante, que permite detectar con alta fiabilidad y robustez la diferencia de fase entre la tensión aplicada a la bobina transmisora y la inducida en la bobina receptora.#El procedimiento de detección se caracteriza por aplicar a la bobina transmisora una señal codificada y modulada digitalmente mediante el uso de una secuencia Kasami. En recepción se realiza la correlación síncrona de la señal recibida con la secuencia Kasami original y su complementaria. Esta doble correlación permite disponer de doble información para tomar la decisión sobre la presencia/ausencia de rueda.
