摘　　要：针对现有动车组故障识别算法存在较高故障识别误报率与漏报率的问题,提出了一种无需预设模板的动车组故障识别算法.将动车组图像以车厢为单位进行划分,以当前列车的其他车厢作为历史图像进行图片比对,确定出故障区域所在的位置.对多种车型的模拟分析结果表明,所提算法在保障检测漏报率的基础上,误报率可降低至少20%.此外,针对复兴号列车,该算法在保持漏报率为12%的条件下,几乎可达到零误报.Aiming at the problem of existing electric multiple units(EMU)fault recognition algorithms with relatively higher false alarm rate and missing alarm rate,an EMU fault recognition algorithm without preset template was proposed.The EMU images were divided into compartments,and the other compartments of current train were used as historical images for comparison,so as to determine the location of fault area.The simulation and analysis results for several vehicle models show that the as-proposed algorithm can reduce the false alarm rate by at least 20%on the basis of ensuring the missing alarm rate.In addition,for China rejuvenation train,the algorithm can achieve almost zero false alarm rate,when keeping the missing alarm rate at 12%.
