Abstract

One embodiment of the present invention is a train control system which is a device executing an exclusive control between trains for each of a plurality of sections dividing up a track, wherein said train control system comprises: an on-ground device which manages whether each of the trains has a right to advance into each of the sections; and, an on-board device which is mounted on the trains, said trains comprising an on-board branch device, and with respect to one of the sections to which the on-ground device has given a certain train the right to advance, if said section is a branch section, which is a section that includes a branch, and when a branch direction of the train in said branch section and a branch direction of the on-board branch device coincide, said on-board device self-determines whether it is possible to advance into said branch section.

Claims (18)

1. A train control system comprising:

a wayside device performing exclusive control between trains in each of a plurality of sections that divide a track, and managing whether or not each of the trains has an approaching right to each of the sections; and

an on-board device mounted on the train including an on-board turnout device, and determining for itself that a turnout section is approachable, in a case where the section determined by the wayside device to which the train has the approaching right is the turnout section which is the section including a turnout, when a turnout direction of the train in the turnout section and a turnout direction of the on-board turnout device coincide with each other.

2. The train control system according to claim 1 ,

wherein the wayside device determines whether or not the train has the approaching right to the section when a request for the approaching right of the train to the section is received from a higher-level device, and

in a case where the wayside device receives the request with respect to a train, when the section relating to the request is the turnout section and the on-board turnout device is not locked, the on-board device causes a turnout direction of the train and a turnout direction of the on-board turnout device in the turnout section to coincide with each other.

3. The train control system according to claim 2 ,

wherein the wayside device sequentially notifies the on-board device of at least a permutation of the sections to which the approaching right is granted, and

the on-board device sequentially notifies the wayside device of at least a current position.

4. The train control system according to claim 1 ,

wherein the wayside device sequentially notifies the on-board device of at least a permutation of the sections to which the approaching right is granted, and

the on-board device sequentially notifies the wayside device of at least a current position.

5. An on-board device mounted on trains including an on-board turnout device,

wherein for a section to which the train has an approaching right, the on-board device determines for itself that a turnout section is approachable, in a case where:

a turnout is present in the section, and

a turnout direction of the train in the turnout section and a turnout direction of the on-board turnout device coincide with each other.

6. A train control method for a train control system including an on-board device mounted on a train including an on-board turnout device, the train control method comprising:

causing the on-board device to determine for itself that a turnout section is approachable, in a case where a turnout is present in the section to which the train has an approaching right, and a turnout direction of the train in the turnout section and a turnout direction of the on-board turnout device coincide with each other.
