Document Type and Number:
Japanese Patent JP2014237349
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve maintenance performance of a passage timing determination system for determining such a timing that a vehicle passes through a prescribed portion and suppresses an increase of load of a maintenance operation.SOLUTION: A passage timing determination system includes: a vibration measurement part for measuring vibrations of a railway structure accompanying passage of a vehicle; a frequency range component extraction part for extracting a component of a frequency range set in accordance with a travelling speed of the vehicle and a size of a prescribed portion of the vehicle from the vibrations measured by the vibration measurement part; and a passage timing determination part for determining such a timing that the prescribed portion of the vehicle passes through the prescribed position on the basis of the component extracted by the frequency range component extraction part.
