Abstract
A train control system includes: an on-board device 3 mounted on each of trains 2; a vehicle radio set 4; wayside radio sets 5 disposed on a ground; and a ground device 6 connected to the wayside radio sets 5. The ground device 6 obtains a location information of a train 2 and a location information of a following train 2 based on results of distance measurement based on communication between the wayside radio sets 5 and the vehicle radio sets 4, and the ground device 6 transmits them to an on-board device 3 of the train 2. The on-board device 3 calculates a stop limit position of the following train 2 based on the location information of the train 2 and the location information of the following train 2, and the on-board device 3 transmits the calculated stop limit position to the following train 2.
Claims4
A train control system comprising:
- an on-board device that is mounted on each of trains travelling on a predetermined track;
- a vehicle radio set that transmits and receives information of the on-board device;
- wayside radio sets that are disposed at predetermined locations;
- and
- a ground device that is connected to the wayside radio sets in a manner capable of transmitting information thereto and receiving information therefrom,
- wherein, with respect to each of the trains, the ground device obtains a location information of a train and a location information of a following train based on results of distance measurement based on communication between the wayside radio set and the vehicle radio set, and the ground device transmits them to an on-board device of the train,
- wherein the on-board device calculates a stop limit position of the following train based on the location information of the train on which the on-board device is mounted and the location information of the following train, which are transmitted from the ground device, and the on-board device transmits the calculated stop limit position to the following train.
