TRACK STATUS MONITORING DEVICE |
摘要 |
Providing a track status monitoring device comprising an acceleration detection unit disposed on a railway car and detecting an acceleration at least in the axle direction among accelerations generated on a wheel of the railway car; a rail position detection unit disposed on the railway car and detecting a value indicating a position of the rail in relation to the wheel in the axle direction; an integration unit that calculates a value based on a 2nd-order integrated value of the acceleration detected by the acceleration detection unit; and a subtraction unit that counterbalances an undulating component of the wheel by subtracting a value detected by the rail position detection unit from a value calculated by the integration unit, and calculates an amount of horizontal-direction displacement of the rail. |

1. A track status monitoring device that detects an amount of horizontal-direction displacement of a rail for a railway car to run, the device comprising:
an acceleration detection unit that is disposed on the railway car and detects an acceleration at least in axle direction among accelerations generated on a wheel of the railway car; a rail position detection unit that is disposed on the railway car, wherein a position of the rail in relation to the rail position detection unit and a position of the wheel in relation to the rail position detection unit are detected, and based on both detected positions, a value indicating a position of the rail in relation to the wheel in the axle direction is detected; an integration unit that calculates a value based on a 2nd-order integrated value of the acceleration detected by the acceleration detection unit; and a subtraction unit that counterbalances an undulating component of the wheel by subtracting a value detected by the rail position detection unit from a value calculated by the integration unit and calculates an amount of horizontal-direction displacement of the rail. |
