摘要: 针对现有带式输送机托辊故障检测方法准确率及效率低等问题，提出一种基于φ-OTDR技术的带式输送机托辊故障检测方法。该方法利用相干脉冲光的后向瑞利散射对托辊的振动信号进行检测，从而实现对异常托辊的识别和定位。实验及测试结果表明，该方法能够实现带式输送机托辊故障检测，故障定位误差不大于5 m。

Abstract: For low correctness and efficiency of existing roller fault detection methods of belt conveyor, a roller fault detection method of belt conveyor based on φOTDR technology was proposed. The method uses backward Rayleigh scattering of coherent pulse light to detect vibration signals of roller, so as to identify and locate fault roller. The experimental and test results show the method can realize roller fault detection of belt conveyor with location error of less than 5 m.
