Abstract

In the present invention, a resource management device receives transmission of a reservation request for a block section to be reserved from among a plurality of block sections included in a track traveled by a vehicle on the basis of track information which indicates the plurality of block sections and the connection relationships of the block sections. In a case where the block section to be reserved, as indicated by the reservation request, has not already been reserved by a vehicle other than the vehicle that transmitted the reservation request at the point in time when such reservation request was received, the following is recorded in a management table: that the block section to be reserved as indicated by the reservation request and a connection boundary between that block section and another block section are objects reserved for the vehicle that transmitted the reservation request.

First claim

The invention claimed is:

1. A vehicle control system comprising:
a traveling management device including a reservation request unit that transmits a reservation request for a block section of a reservation target to a resource management device among a plurality of block sections included in a track traveled by a vehicle based on track information indicating the plurality of block sections constituting the track of the vehicle and a connection relationship between the block sections; and
the resource management device including a reservation management unit that records all of block sections of the reservation target indicated by the reservation request and each of connection boundaries between all of the block sections of the reservation target and another block section on an advancing direction of the vehicle transmitting the reservation request in a first reservation management table as a reserved target of the vehicle transmitting the reservation request in a case where each of the block sections of the reservation target indicated by the reservation request is not reserved in the first reservation management table by a vehicle other than the vehicle transmitting the reservation request at a time of reception of the reservation request.

2. The vehicle control system according to claim 1 ,
wherein in a case where one of the connection boundaries is recorded in the first reservation management table as the reserved target, the reservation management unit of the resource management device rejects the reservation request for a block section having the one connection boundary.

3. The vehicle control system according to claim 1 ,
wherein in a case where one of the connection boundaries that is positioned in the advancing direction of the vehicle between connection boundaries at both ends of one of the block sections of the reservation request from the vehicle is recorded in the first reservation management table as the reserved target, the reservation management unit of the resource management device rejects the reservation request for a block section having the one connection boundary.

4. The vehicle control system according to claim 1 , wherein the resource management device includes
a first resource management device that performs reservation management of the block sections using the first reservation management table, and
a second resource management device that records the block sections of the reservation target indicated by the reservation request in a second reservation management table as the reserved target of the vehicle transmitting the reservation request without recording the connection boundaries disposed in the block sections of the reservation target indicated by the reservation request as the reserved target and performs reservation management of the block sections using the second reservation management table in a case where each of the block sections of the reservation target indicated by the reservation request is not reserved by the vehicle other than the vehicle transmitting the reservation request at the time of reception of the reservation request, and
the reservation request unit of the traveling management device transmits the reservation request to any of the first resource management device or the second resource management device disposed in correspondence with a position of the vehicle traveling on the track.

5. The vehicle control system according to claim 4 , wherein
the first resource management device performs a process based on a reservation request for each block section installed in a first management area, and
the second resource management device performs a process based on a reservation request for each block section installed in a second management area.

6. The vehicle control system according to claim 1 , wherein
the first reservation management table stores identification information of one of the block sections in association with a reservation state of the one block section,
the resource management device includes a malfunction detection unit that detects a malfunction of the vehicle, and
in a case where the malfunction of the vehicle is detected, the reservation management unit of the resource management device updates the reservation state of the one block section reserved by the vehicle to a train malfunction and deletes a recording of the first reservation management table for a corresponding connection boundary of the connection boundaries as the reserved target.

7. The vehicle control system according to claim 6 ,
wherein the resource management device records a block section reserved by the vehicle having the detected malfunction in the first reservation management table as a block section of a reserved target reserved by a rescue vehicle connected to a malfunctioning vehicle.

8. A resource management device included in a vehicle control system, comprising:
a reservation management unit that
makes communication connection to a traveling management device including a reservation request unit that transmits a reservation request for a block section of a reservation target to a resource management device among a plurality of block sections included in a track traveled by a vehicle based on track information indicating the plurality of block sections constituting the track of the vehicle and a connection relationship between the block sections, and
records all of block sections of the reservation target indicated by the reservation request and each of connection boundaries between all of the block sections of the reservation target and another block section on an advancing direction of the vehicle transmitting the reservation request in a first reservation management table as a reserved target of the vehicle transmitting the reservation request in a case where each of the block sections of the reservation target indicated by the reservation request is not reserved in the first reservation management table by a vehicle other than the vehicle transmitting the reservation request at a time of reception of the reservation request.

9. The resource management device according to claim 8 ,
wherein in a case where one of the connection boundaries that is positioned in the advancing direction of the vehicle between connection boundaries at both ends of the block section of the reservation request from the vehicle is recorded in the first reservation management table as the reserved target, the reservation management unit rejects the reservation request for a block section having the one connection boundary.

10. The resource management device according to claim 9 , wherein
the first reservation management table stores identification information of one of the block sections in association with a reservation state of the one block section,
the resource management device includes a malfunction detection unit that detects a malfunction of the vehicle, and
in a case where the malfunction of the vehicle is detected, the reservation management unit of the resource management device updates the reservation state of the one block section reserved by the vehicle to a train malfunction and deletes a recording of the first reservation management table for a corresponding connection boundary of the connection boundaries as the reserved target.

11. The resource management device according to claim 10 ,
wherein the reservation management unit records a block section reserved by the vehicle having the detected malfunction in the first reservation management table as a block section of a reserved target reserved by a rescue vehicle connected to a malfunctioning vehicle.

12. A vehicle control method comprising:
