Method and system for detecting aging state of pressure vessel

By collecting sound signals by tapping the pressure vessel and performing frequency domain analysis, the problem of needing to stop the operation for detection in existing technologies has been solved. This enables low-cost, non-destructive aging condition detection, improving the accuracy and ease of detection.

Abstract

The invention discloses a method and system for detecting the aging state of a pressure vessel. The method comprises the steps that a target pressure vessel is knocked, and sound signals and sound wave signals generated under the knocking effect are collected; converting the collected sound signal into an audio analog signal to obtain a sound vibration waveform, then generating a new sound wave signal according to the sound vibration waveform, and correcting the collected sound wave signal by using the current new sound wave signal; and performing frequency domain analysis on the corrected sound wave signal, thereby obtaining an aging state detection result of the current target pressure vessel according to a frequency domain analysis result. According to the invention, accurate detection of the aging state of the pressure vessel is realized under the conditions of any working state of the pressure vessel and no damage to the structure and the function of the vessel.
