Abstract
A forward monitoring device for a train includes: a storage unit storing map information representing location information and a track geometry of a track and brake performance information representing performance of a train brake system; a train information acquisition unit obtaining train location information and train speed information; a monitoring unit monitoring an upside of the track in the travel direction; an obstacle determination unit determining presence or absence of an obstacle on the track based on a monitoring result of the monitoring unit; a braking distance calculation unit calculating a train braking distance using the map, brake performance, train location, and train speed information, and a processing time from when the monitoring unit performs monitoring until determination on presence or absence of an obstacle; and a monitoring distance determination unit determining a monitoring distance based on the braking distance to set a monitoring range of the monitoring unit.
