Document Type and Number:
WIPO Patent Application WO/2018/123679
Kind Code:
A1
Abstract:
In order to present information more appropriate for preventing collisions between trains while minimizing installation costs and maintenance costs even when train travel is assumed to take place on a plurality of tracks, this train-installed device is provided with: a wireless communication means that performs wireless communication via an antenna installed at the front of a host train; a train information acquisition means that acquires train information including information representing the track on which the host train is running; a search signal transmission means that transmits a search signal for searching for another nearby train from the wireless communication means; a collision possibility assessment means that, upon receiving from the wireless communication means a response signal transmitted by a second train-installed device installed on another train, assesses whether there is a possibility of a collision between the host train and the other train on the basis of train information included in the response signal and the train information acquired using the train information acquisition means; and a distance measurement means that measures the distance between the other train and the host train when there is assessed to be a possibility of a collision.
