Document Type and Number:
WIPO Patent Application WO/2013/175930
Kind Code:
A1
Abstract:
Provided is a track status monitoring device provided with: an acceleration detection section provided on a railway car, said acceleration detection section detecting, from among accelerations generated on a wheel of the railway car, at least an acceleration in a wheel axle direction; a rail position detection section provided on the railway car, said rail position detection section detecting a value indicating a wheel-axis-direction position of a rail relative to the wheel; an integral computation section that computes a value based on a double integral of the acceleration detected by the acceleration detection section; and a subtraction computation section that by subtracting, from the value computed by the integral computation section, the value detected by the rail position detection section, offsets the meandering component of the wheel and computes a displacement quantity in the left/right direction of the rail.
