列車位置検出装置
Document Type and Number:
Japanese Patent JP7343153
Kind Code:
B2
Abstract:
To provide a technique by which a train position can be detected inexpensively and reliably.SOLUTION: An optical radar 30 of a train apparatus 10 has: light irradiation means 40 which can irradiate a prescribed area of a flat surface 31 on a train front side with light at different irradiation angles with respect to a train travel direction; and light reception means 50 which can receive reflectance such that the emitted light has been reflected by an object. An outer peripheral shape of the object, which exists in the front of a train 200, is discriminated on the basis of the light irradiation angle and the time (reflection time) from light irradiation to light reception. Storage means 60 has: object information database in which the outer peripheral shape and a reference point of the object existing along a track 100 are stored; and positional information database in which object identification information at each position along the track 100, and position reference information including a direction of the reference point of the object and a distance to the reference point are stored corresponding positional information. A position of the train 200 is detected on the basis of the discriminated outer peripheral shape of the object, object information database and positional information database.SELECTED DRAWING: Figure 1
