Abstract

A train information management device sends and receives information to and from both a train-controlling in-vehicle wireless station for controlling an operation of a train, and a door-controlling in-vehicle wireless station for controlling vehicle doors. The device includes a wireless train control unit, an automatic operation unit, and a door control unit. The wireless train control unit receives route information represented by a consecutive block sequence and information on a stop limit location that the train may reach without hindering a preceding train, and if this route information includes a station block number, consults an in-vehicle database to extract, before the train arrives at a platform, an arrival track where the train is to stop, a stop target location at a stop station dependent on a travel direction of the train, and which of the vehicle doors is to be opened, and stops the train in accordance with the route information.

First claim

The invention claimed is:

1. A train information management device comprising:
a train-controlling in-vehicle wireless station to receive from a ground-located control device, route information indicated by a consecutive block sequence and information on a stop limit location; and
a wireless train controller to, before a train arrives at a stop station, refer to a station block number and a station block number mapping table in an in-vehicle database to extract information regarding an arrival track at the stop station, a stop target location at the stop station, and a side on which to open a vehicle door of the train, and stop the train in accordance with the route information, the station block number being extracted from the route information indicated by the consecutive block sequence and the information on the stop limit location received from the train-controlling in-vehicle wireless station, the in-vehicle database being disposed on the train.

2. The train information management device according to claim 1 , further comprising:
a door controller to control opening and closing of the vehicle door of the train,
wherein the wireless train controller sends to the door controller the information regarding the arrival track at the stop station and information on the door opening side at the stop station.

3. The train information management device according to claim 2 , further comprising:
an automatic operation controller to automatically control an operation of the train in accordance with an instruction from the wireless train controller,
wherein, after the train stops, the automatic operation controller sends to the wireless train controller a door open instruction to open a platform door installed in the stop station and open the vehicle door of the train.

4. The train information management device according to claim 2 , further comprising:
an automatic operation controller to automatically control an operation of the train in accordance with an instruction from the wireless train controller,
wherein, after the train stops, the automatic operation controller sends to the door controller a door open instruction to open a platform door installed in the stop station and open the vehicle door of the train.

5. The train information management device according to claim 4 , wherein, after reception of the door open instruction, the door controller sends a platform door open instruction to a platform door control device to control opening and closing of the platform door.

6. The train information management device according to claim 3 , wherein the wireless train controller sends a vehicle door open instruction to the door controller, and sends a platform door open instruction to a platform door control device to control opening and closing of the platform door.

7. A door control system comprising:
a train-controlling in-vehicle wireless station to receive from a ground-located control device, route information indicated by a consecutive block sequence and information on a stop limit location, and
a train information management device including a wireless train controller to, before a train arrives at a stop station, refer to a station block number and a station block number mapping table in an in-vehicle database to extract information regarding an arrival track at the stop station, a stop target location at the stop station, and a side on which to open a vehicle door of the train, and stop the train in accordance with the route information, the station block number being extracted from the route information indicated by the consecutive block sequence and the information on the stop limit location received from the train-controlling in-vehicle wireless station, the in-vehicle database being disposed on the train; and
a platform door control device to control opening and closing of a platform door installed in the stop station,
wherein the train and the platform door control device wirelessly communicate with each other to provide cooperative control between the vehicle door of the train and the platform door.
