The current inspection strategy of energy supply pipeline is not pure enough to extract the pipeline defect fea-tures,resulting in poor defect positioning accuracy.Therefore,a comprehensive intelligent inspection strategy of energy supply pipeline mobile GIS based on improved empirical wavelet transform model is proposed.The mobile GIS technology is used to collect the pipeline data,and the improved empirical wavelet transform model is used to extract the pipeline defect features according to the pipeline data.The subband self decomposition of the tree structure can accurately distinguish the defect source signal and other interference signals,extract more pure defect features,and filter the feature set of the defect feature vector,so as to calculate the specific location of the pipeline defects.In the experimental demonstration,the positio-ning accuracy of the proposed strategy is verified.The results show that the proposed strategy is applied to the routing in-spection of energy supply pipeline,and the positioning accuracy of pipeline defects is high.
