TRAIN CONTROL SYSTEM

摘要

Provided is a train control system capable of correctly detecting a phase difference in an amplitude-modulated wave without increasing sampling frequency. A train control system is provided with: a ground device (1) that transmits a predetermined train control signal; and an on-board device (3) that receives the train control signal transmitted from the ground device (1) and controls a train (2). The ground device (1) phase-modulates an amplitude-modulated wave constituting the train control signal at predetermined time intervals and transmits the modulated wave to the on-board device (3).
