摘要:
目的：由于巡道检查工作纯作业的时间少，检测的项目多，检测的范围大且距离长，现有的以人工巡道检查的检测方式已经不能满足其要求，因此寻求提高检测效率的新手段势在必行。方法：通过在地铁列车上安装轨道高速智能巡检系统，利用5G(第五代移动通信技术)网络快速传输图像；通过深度学习算法实现轨面擦伤或掉块、波磨、光带异常、焊缝、弹条或螺栓缺失、弹条歪斜、弹条断裂以及轨道板裂纹和轨道异物等在线智能识别。结果及结论：在南昌地铁1号线近3个月的试用结果表明：该系统可检测钢轨顶面伤损、扣件缺陷、轨道板缺陷等病害和轨道异物。其识别率不小于95%，误报率不大于5%，识别率高、重复性好；同时，不占用天窗时间，可做到日日检，改变了传统巡道方式；对轨道结构表面状态的检查可做到全天候的检测，从而产生隐含的不可估算的经济效益和社会效益。

Objective: Due to the limited working time, numerous inspection tasks, extensive inspection coverage, and long distance involved in track inspection work, the existing manual inspection methods are no longer sufficient to meet the requirements. Therefore, there is an imperative need for developing new means to enhance inspection efficiency. Method: The highspeed intelligent inspection system for tracks is installed on metro trains, utilizing 5G (fifth generation) mobile communications technology for rapid image transmission. Deep learning algorithms are employed to achieve realtime intelligent identification of track surface abrasions or detachment, corrugation, abnormal light bands, weld seams, missing fasteners or bolts, misaligned fasteners, broken fasteners, track plate cracks, and foreign objects on the track. Result & Conclusion: The trial results from the pass three months on Nanchang Metro Line 1 indicate that the system can detect diseases such as damage on rail top surface, fastener defects, track plate deficiencies, and foreign objects on the track. The recognition rate is not less than 95%, with a false alarm rate of not more than 5%, demonstrating high recognition rate and good repeatability. At the same time, it does not occupy the track inspection window time, enabling daily inspections and transforming conventional track inspection methods. With the possibility of daily allweather inspection work of track surface conditions, incalculable hidden economic and social benefits can be generated.
