<p>PROBLEM TO BE SOLVED: To provide a train control apparatus capable of discerning between a signal portion and a non-signal portion of a train control signal correctly, and demodulating a phase difference of a signal correctly.SOLUTION: A train control apparatus includes an on-vehicle device 3 to control a train 2 by receiving a train control signal transmitted from a ground apparatus 1, so that the on-vehicle device 3 calculates an average value of maximum values of amplitude-modulation waves constituting a received train control signal and determines a signal portion and a non-signal portion of the amplitude-modulation waves using the average value as a threshold.</p> |
