WHEEL SLIP/SKID DETECTION DEVICE AND WHEEL SLIP/SKID DETECTION METHOD

WIPO Patent Application WO/2022/249280

A1

A wheel slip/skid detection device (20) installed in a train comprises: a change detection unit (21) that periodically acquires a first detected value from a speed sensor (50) for detecting the rotation state of a wheel of the train, uses a plurality of the first detected values to calculate a first change amount, periodically acquires a second detected value from an acceleration sensor (60) for detecting the acceleration of the train, uses a plurality of the second detected values to calculate a second change amount, and uses the first change amount, the second change amount, a first threshold value, and a second threshold value to select and output a change mode from a plurality of change modes that have been defined in order to determine whether wheel slipping or skidding has occurred in the train; and a wheel slip/skid determination unit (22) that determines whether wheel slipping or skidding has occurred in the train on the basis of the change mode acquired from the change detection unit (21) and determines whether a failure has occurred in either the speed sensor (50) or the acceleration sensor (60).
