Simulation of Gas Pipeline Leak Detection Based on Acoustic Emission and Wavelet Packet Analysis
In this article acoustic emission sensors were used to detect simulation of gas pipeline leak and the acoustic emission signals of a pipeline leak were obtained. Acoustic emission technology was adopted to detect pipeline leak. First wavelet packet decomposition methods were used to decompose the acoustic emission signals; then the attenuated signals were remedied effectively at different frequencies. The cross-correlation technology was used to calculate the delay-time received by the two acoustic emission sensors. This method effectively solved the difficulty that the existing acoustic emission system was difficult to detect continuous signals, such as pipeline leakage giving a larger leakage location error. The proposed method pipeline leakage location error is less than 8%.
