Abstract

With respect to each of trains, a ground device 6 detects a train location in the control section on the basis of a propagation time of a radio wave between a vehicle radio set 4 and a wayside radio set 5, in the case in which the ground device 6 determines that the number of trains has reached the controllable number of trains or there is the possibility that the number of trains reaches the controllable number of trains in its own control section, a ground device 6 disposed in an adjacent control section to the control section in which the number of trains is reaching the controllable number of trains, when a train 2 scheduled to travel toward the control section stops in a station 8, prevents departure of the train 2 scheduled to pass through the border of the control section by making the train 2 wait at the station 8.

Claims3

Dependent claims

A train control system comprising:

a vehicle radio set that is mounted on a train traveling on a predetermined track;
wayside radio sets each of which is disposed at a predetermined location on the ground;
and
ground devices each of which is disposed in each of control sections which are set in the track and connected to the wayside radio set belonging to the control section so as to be able to transmit and receive information,
wherein, with respect to each of trains, the ground device detects a train location in the control section on the basis of a propagation time of a radio wave between the vehicle radio set and the wayside radio set, in the case in which the ground device determines that the number of trains has reached the controllable number of trains or there is the possibility that the number of trains reaches the controllable number of trains in the control section, a ground device disposed in an adjacent control section to the control section in which the number of trains is reaching the controllable number of trains, when a train scheduled to travel toward the control section stops at a station, prevents departure of a train scheduled to pass through the border of the control section by making the train wait at the station.
