WIPO Patent Application WO/2017/221611

A1

Through the present invention, abnormality diagnosis having better precision than the prior art is performed while cost is reduced. A vibration measurement device according to an embodiment of the present invention is fixed to an object which moves along a track, and measures vibration of the object. A first transmission device configured to transmit a first trigger signal toward a first measurement point on the track, and a second transmission device configured to transmit a second trigger signal toward a second measurement point on the track different from the first measurement point are disposed along the track. The vibration measurement device is provided with a vibration sensor, a reception unit, and a storage unit. The vibration sensor is configured to measure vibration data of the object. The reception unit is configured to receive the first trigger signal and the second trigger signal. The storage unit is configured to store vibration data after reception of the first trigger signal and the second trigger signal, and information necessary for determining the movement speed of the object.
