中文摘要:当前供能管道巡检策略由于对管道的缺陷特征提取不够纯净,导致缺陷定位准确度差,因此,提出了基于改进经验小波变换模型的供能管道移动GIS综合智慧巡检策略。利用移动GIS技术采集管道数据,根据管道数据采用改进经验小波变换模型对管道缺陷特征进行提取,其树状结构的子频带自分解能够准确分辨出缺陷源信号与其他干扰信号,提取到更加纯净的缺陷特征,并对缺陷特征向量特征集进行滤波,从而计算出管道缺陷的具体位置。在实验论证中,对提出的策略的定位准确性进行了验证,结果表明,提出的策略应用于供能管道巡检中,对管道缺陷定位的准确性较高。

Integrated Intelligent Inspection Strategy for Mobile GIS of Energy Supply Pipeline Based on Improved Empirical Wavelet Transform Model
Abstract:The current inspection strategy of energy supply pipeline is not pure enough to extract the pipeline defect features, 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 positioning accuracy of the proposed strategy is verified. The results show that the proposed strategy is applied to the routing inspection of energy supply pipeline, and the positioning accuracy of pipeline defects is high.
