摘要
针对传统的输变电线路铁塔金属缺陷检测方法存在缺陷定位精度低、漏检率高的问题,提出基于光谱分析法的输变电线路铁塔金属缺陷检测方法。采用光谱特征挖掘方法,提取输变电线路铁塔金属缺陷光谱信息特征,构建电磁辐射以及电磁辐射物质参数融合模型,获取参数融合统计量,在此基础上,对输变电线路铁塔金属缺陷光谱信号进行频谱检测,分析变电站金属监督设备检测中的材质部件,并定位输变电线路铁塔金属光谱缺陷,根据缺陷点的动态响应及参数摄动分析,实现输变电线路铁塔金属缺陷检测。仿真结果表明,采用该方法进行输变电线路铁塔金属缺陷检测的漏检率较低,缺陷定位性能较好。
Aiming at the problems of low accuracy of defect location and high rate of missing detection in traditional metal defect detection methods of transmission and transformation line tower,a metal defect detection method based on spectral analysis method is proposed.The spectral feature mining method is used to extract the spectral information features of metal defects in power transmission and transformation line towers,and the fusion model of electromagnetic radiation and electromagnetic radiation material parameters is constructed,and the parameter fusion statistics are obtained.On this basis,the spectrum detection of metal defect spectral signal of transmission and transformation line iron tower is carried out,and the material components in the detection of substation metal supervision equipment are analyzed,and the transmission and transformation are located.According to the dynamic response of defect points and parameter perturbation analysis,the metal defect detection of transmission and transformation tower is realized.The simulation results show that the rate of missing detection is low and the performance of defect location is good.
