Optical fiber vibration model determination method and device

The invention discloses an optical fiber vibration model determination method and device. The method includes obtaining a vibration signal of a target optical fiber position; extracting frequency spectrum features of the vibration signal; matching the frequency spectrum features with the frequency spectrum features of a preset vibration model; determining that the vibration signal belongs to the preset vibration model if the frequency spectrum features are matched with the frequency spectrum features of the preset vibration model. By adopting the above method, the vibration type of the target optical fiber position can be judged accurately and the optical fiber vibration detection efficiency is improved.
