Development of Train Approach Alarm System Applicable within Station Yard

Satoshi SEKINE,  Kiyotaka SEKI


  We developed a system to give the alarm for approaches of trains to workers alongside railways, which works most effectively on the assumption that information of approaches of trains is obtained through existing signaling equipments. We constructed an algorithm to predict courses of trains in station yards correctly, identifying tracks from which the workers had to leave, which had not been realized until now. We also developed a track database which relates coordinates of tracks represented by latitude and longitude with those of signaling equipments drawn in interlocking charts. As a result, we can predict tracks to which alarms should be issued by using information received from interlocking device and easily obtain coordinates of the tracks in a real world. Information about tracks to which an incoming of a train is predicted is displayed on the terminal equipment which a worker carries, and a warning to direct him to leave the track is put out from the equipment.
