Development of PC-Based Leak Detection System Using Acoustic Emission Technique

摘要

This research is focused on developing an advanced AE source location system including new concept waveform processing. In the present research, the source location system is designed to detect leak location more accurately at faster speed with less cost. Basically, this system is comprised of two different source location modes such as one-dimensional mode (leak detection in pipeline) and two-dimensional mode (source detection in plate). Generally, since the AE waveforms obtained from the various sources are very complicated, it is difficult to distinguish the original signals clearly. Wavelet transform is a powerful tool for processing transient signals with temporally varying spectra that helps to resolve high and low frequency transient components effectively. In this paper, the source location results are also presented by employing the wavelet transform.
