[Scope of Claim for Utility Model Registration] (1) A vibration detection means for detecting vibration, and the time dependence of the vibration detected by the vibration detection means during one batch drive period from when the object to be measured starts, continues to operate, and finally stops. a normal pattern storage means for pre-memorizing a vibration pattern during normal operation; and a reference pattern obtained by multiplying the normal pattern amplitude stored in the normal pattern storage means by a constant for the vibration detected by the vibration detection means during operation. Batch drive line abnormality diagnosis characterized by comprising a comparison means for comparing with a reference value obtained based on the above, and a display means for issuing an alarm when the comparison means determines that the reference value has been exceeded within one batch drive period. vessel. (2) In the batch drive line abnormality diagnostic device recited in claim 1, the vibration detection means includes moving average calculation means for calculating a moving average for each of a predetermined number of detected values, A batch drive line abnormality diagnostic device characterized by outputting a moving average value.
