Document Type and Number:
WIPO Patent Application WO/2023/282028
Kind Code:
A1
Abstract:
Provided is a state monitoring apparatus for a mechanical apparatus including a rolling bearing, the apparatus including: a first acquisition means that acquires vibration information or sound information of the rotating rolling bearing; a second acquisition means that acquires a rotation speed of the rotating rolling bearing; a derivation means that derives a timing of sampling data from the vibration information or the sound information on the basis of the rotation speed so that a sampling number per one rotation of the rolling bearing becomes a predetermined value; and a generation means that samples data from the vibration information or the sound information on the basis of the timing derived by the derivation means to generate monitoring data.
