发明名称 METHODS AND SYSTEM FOR JOINTLESS TRACK CIRCUITS USING PASSIVE SIGNALING
摘要 The present disclosure describes methods and systems for connecting passive signaling devices ("PSDs") to a railroad track and using the PSDs to optimize the amplitude, modulation, coding, and frequency of waveforms that applied to the track (by signaling points) for at least three track circuit functions: detecting trains, detecting broken rails, and communicating between signaling points and PSDs.
