Abstract:
[Problem] To provide an abnormality detection device capable of detecting an abnormality on a track.[Solution] The present invention comprises: an acquisition section that acquires a threshold excess time indicating the time at which a characteristic value of a physical quantity of each drive system disposed in a rail vehicle exceeds a threshold and a drive system position indicating the position of the drive system with respect to the rail vehicle at the threshold excess time; a determination section that determines whether or not there is a correlation between the plurality of threshold excess times and the drive system positions at the threshold excess times acquired for the plurality of drive systems disposed in the rail vehicle by the acquisition section; and an output section that performs output on the basis of the determination result of the determination section. If it is determined by the determination section that there is a correlation, the output section outputs a track abnormality signal indicating that there is an abnormality on the track.
