摘要：

The recognition of abnormal dynamic pressure wave signal is key to pipeline leakage detection. Permutation entropy algorithm can effectively amplify slight changes of time series data and has advantages of easily computing and good performance in change detection. The weighted-permutation entropy which is based on the permutation entropy considers the amplitude information. In this study, the weighted-permutation entropy is utilized to detect the pipeline leakage. To prove the effectiveness of the method, typical experiments are performed on the test platform. Results show that the weighted-permutation entropy method can successfully detect the pipeline leakage.
