Abstract:
(EN) 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.
(FR) L'invention, afin de présenter des informations plus appropriées pour empêcher des collisions entre des trains tout en réduisant au minimum les coûts d'installation et les coûts de maintenance même quand un déplacement de train est supposé avoir lieu sur une pluralité de voies ferrées, concerne ce dispositif installé dans un train comportant : un moyen de communication sans fil qui réalise une communication sans fil par l'intermédiaire d'une antenne installée à l'avant d'un train hôte ; un moyen d'acquisition d'informations de train qui acquiert des informations de train comprenant des informations représentant la voie ferrée sur laquelle le train hôte se déplace ; un moyen de transmission de signal de recherche qui transmet un signal de recherche à des fins de recherche d’un autre train voisin à partir du moyen de communication sans fil ; un moyen d'évaluation de possibilité de collision qui, lors de la réception en provenance du moyen de communication sans fil d’un signal de réponse transmis par un deuxième dispositif installé sur un train installé sur un autre train, détermine s'il existe une possibilité de collision entre le train hôte et l'autre train en fonction des informations de train incluses dans le signal de réponse et des informations de train acquises par le biais du moyen d'acquisition d'informations de train ; et un moyen de mesure de distance qui mesure la distance entre l'autre train et le train hôte quand il est déterminé qu'il y a une possibilité de collision.
(JA) 複数の線路において列車の走行が想定される場合にも、設置コストや保守コストを抑えながら、列車間の衝突を防止するためのより適切な情報を提示するため、本発明の列車搭載装置は、自列車の前方に設置されたアンテナを介して無線通信を行う無線通信手段と、自列車が在線中の線路を表す情報を含む列車情報を取得する列車情報取得手段と、近隣の他列車を探索する探索信号を無線通信手段から送信する探索信号送信手段と、他列車に搭載された第2の列車搭載装置によって送信された応答信号を無線通信手段から受信すると、応答信号に含まれる列車情報および列車情報取得手段を用いて取得された列車情報に基づいて自列車および他列車間の衝突の可能性の有無を判断する衝突可能性判断手段と、衝突の可能性があると判断された場合に、他列車および自列車間の距離を測定する距離測定手段とを備える。
