Design of Acoustic Emission Monitoring System for Pressure Vessel Defects Over Design Life Based on Lab VIEW

Aiming at the defects of the pressure vessel over the designed service life, a set of acoustic emission monitoring system with real-time monitoring function is designed with Lab VIEW software as the core. The system includes the acquisition, storage and playback of acoustic emission signals, analysis of key parameters and other functions, and combines the powerful signal processing capability of Python through interface functions. The signal is denoised and the Gauss Newton location algorithm is used to locate the defects of the pressure vessel beyond the designed service life quickly and accurately.
