| 摘要 |
<p>The present invention relates to a method for determining the state of a vibration device based on a vibration sensing signal of the vibration device and, more particularly, to a method for determining the state of the vibration device with a sate corresponding to the determined reference sensing signal by determining a reference vibration sensing signal which is the most similar to the vibration sensing signal based on the similarity of spectrum data generated from the vibration sensing signal of the vibration device and reference spectrum data generated from the reference vibration sensing signal.</p> |
