A train control system includes an on-board device 3 mounted on a train 2; a vehicle radio set 4; wayside radio sets 5 that are disposed on a ground; and ground devices 6 disposed in every control sections defined on the track. In each control section, the ground device 6 is connected to the wayside radio sets 5 in the control section. When one ground device 6 fails to transmit information to and receive information from another ground device 6, the one ground device 6 determines that said another ground device 6 has been failed, and then, the one ground device 6 calculates a possible travel distance to a control section of the failed ground device 6 to prevent the train 2 from entering the control section of the failed ground device 6, and then, the one ground device 6 transmits the possible travel distance to the on-board device 3.

A ground device 1 transmits train control information to an on-board device mounted on a train. The ground device 1 receives a train detection signal (TD signal) from a train with an ATC/TD on-board device mounted thereon through loop coils 2_(1 )to 2_(m), and receives a train position signal from a train with a CBTC on-board device mounted thereon through wayside radio sets 6_(1 )to 6_(n). Based on the input train detection signal and train position signal, the ground device 1 detects the position of each train traveling on a route R, generates control information on each train based on the detected position of each train, and converts the control information to an ATC signal and a CBTC signal. The ATC signal is transmitted to the loop coils 2_(1 )to 2_(m )through information transmission units 4, and the CBTC signal is transmitted through the wayside radio sets 6_(1 )to 6_(n).

The present invention relates to a train control device. The train control device sets an emergency brake pattern and a regular brake pattern as patterns of maximum speed according to the distance to a stopping point, and outputs a braking command when the train speed exceeds the maximum speed. Then, when the maximum speed defined in the regular brake pattern falls below a set speed, the maximum speed of the regular brake pattern is kept constant for a predetermined distance. After that, the maximum speed is gradually reduced toward a stopping point of the emergency brake pattern. This allows a train to make an approach to a fixed stopping position in an automatic train operation even when the fixed stopping position is located farther than a stopping point of the regular brake pattern, and excessive output of an emergency braking command based on the emergency brake pattern can be reduced.
