| 摘 要： | 传统扣件检查基本采用人工检查方式，不仅工作效率低、劳动强度大，而且人为干扰因素多、检查采样率低。针对以上问题，本文提出了一种基于线结构光传感器的轨道扣件损伤和松动检测方法，并开发了轨道扣件智能监测系统以实现扣件病害自动检测。最终将研究成果应用于徐州市某地铁区间轨道扣件检测，验证了该方法的可行性和准确率，为地铁轨道扣件检查提供了新方法。

| Abstract: | The traditional fastener inspection basically adopts manual inspection method, which not only has the disadvantages of low work efficiency and high labor intensity, but also has the disadvantages of many human factors interference and low inspection sampling rate. To solve these problems, this paper proposes a method for detecting damage and loosening of rail fasteners based on a line structure light sensor, and develops an intelligent monitoring system for rail fasteners to realize detecting damage automatically. Finally, the research results are applied to the detection of rail fasteners in a subway section of Xuzhou city, and the method is verified with feasibility and accuracy, which provides a new method for the inspection of subway track fasteners. |
