System and method for analyzing signals travelling along track circuits of railway lines, and related portable signal analyzing device

摘要

System, method and portable device for analyzing signals travelling along track circuits of railway lines, wherein at least one antenna captures, in a contactless manner, a plurality of signals travelling along a track circuit, and a demodulator is adapted to separate into individual signals the plurality of signals captured by the antenna and selectively demodulate one or more of the captured signals. An interface is adapted for transferring, to a user interface, data indicative of the demodulated signals. Each demodulated signal is displayed on a screen for a user to trigger any needed corrective action.
