摘要

Monitoring of ship pipeline leakage detecting is one of the most importantrntechniques to be developed as it can help to prevent damages of ship working safe. Inrnthis paper, wavelet transform is used as a tool, to characterize the real time pipelinernflow signal during ship working. Firstly, we use the Mallat algorithms to get thernstandard wavelet transform result from the pipeline flow signal. During the detectionrnperiod, we get the real time wavelet transform result on certain level through the realrntime wavelet algorithms. The real time wavelet results of both sides were examinedrnby the correlation to its normal result. According to the magnitude of the correlationrnfactors, we can make sure whether the normally. The results of simulation show thatrnthe selected monitoring indices from the wavelet coefficients are capable of detectingrnin the ship pipeline leakage effectively.
