TRAIN POSITION DETECTION DEVICE AND METHOD

Title:

TRAIN POSITION DETECTION DEVICE AND METHOD

Document Type and Number:

WIPO Patent Application WO/2018/034341

Kind Code:

A1

Abstract:

Provided in an embodiment is a railroad design standard storage unit of a train position detection device, said railroad design standard storage unit storing therein in advance a railroad design standard for a track on which trains run. Then, a position detection unit detects the position of a train by self-contained navigation on the basis of an input signal from a self-contained navigation sensor, in parallel to an operation of detecting the position of the train by receiving measurement radio waves from a plurality of satellites via a reception antenna. In this case, when the detection result of the position of the train obtained by measurement radio waves does not satisfy the railroad design standard, the position detection unit corrects the detection result of the position of the train obtained by measurement radio waves by using the detection result of the position obtained by the self-contained navigation. Thus, in the case where a position detection system needs to be provided to a vehicle of a train after certification of the vehicle, a reduction in position accuracy can be suppressed even for a place where the measurement radio waves from satellites cannot be directly received.
