Abstract
A spinning and sliding detection device in a train includes: a change detection unit that periodically acquires a first detected value from a speed sensor, calculates a first change amount, using the first detected values, periodically acquires a second detected value from an acceleration sensor, calculates a second change amount, using the second detected values, and selects a change mode from a plurality of change modes defined for determining whether spinning or sliding has occurred at the train, using the first change amount, the second change amount, a first threshold, and a second threshold and outputs the selected change mode; and a spinning and sliding determination unit that determines whether spinning or sliding has occurred at the train and determines whether an anomaly has occurred in either the speed sensor or the acceleration sensor, based on the change mode acquired from the change detection unit.
