Defect analysis apparatus, defect analysis system, defect analysis method, and computer-readable recording medium

摘要

Presence of piping defects is determined with high accuracy. The defect analyzer determines the first frequency band based on the first vibration generated from the first point within a predetermined range from the installation point of the vibration detection unit capable of detecting the vibration generated in the pipe, A frequency determining unit that determines a second frequency band based on second vibrations generated from different second points and determines a leakage frequency band based on the first frequency band and the second frequency band; and vibration in the leakage frequency band And a signal processing unit for determining a defect between the first point and the second point based on the vibration level.
