1. A spinning and sliding detection device to be installed in a train, the device comprising:
change detection circuitry to periodically acquire a first detected value from a first sensor to detect a rotational state of a wheel of the train, calculate a first change amount, using the first detected values, periodically acquire a second detected value from a second sensor to detect speed or acceleration of the train, calculate a second change amount, using the second detected values, and select a change mode on a basis of a combination of 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 different from the first threshold for obtaining the plurality of change modes, and output the selected change mode; and
spinning and sliding determination circuitry to determine whether spinning or sliding has occurred at the train and determine whether a failure has occurred in either the first sensor or the second sensor, on a basis of the change mode acquired from the change detection circuitry.
