The invention belongs to the technical field of rail traffic rail detection, and discloses a method for online detection of a rail corrugation fault. According to the rail corrugation fault detection method, a mode of carrying out weighted calculation on the rail corrugation indexes of the four measuring points on one side of the train is introduced, the reliability of the rail corrugation evaluation indexes is improved, and misjudgment caused by the abnormal state of individual wheels is effectively avoided; whether the maximum deviation of rail corrugation wavelength indexes of four measuring points on one side of a train is smaller than a deviation coefficient or not is introduced as an alarm condition, and misjudgment caused by abnormities of three to four wheels is effectively avoided. According to the rail corrugation fault detection method, the monitoring result is accurate and stable, the requirement for system performance is low, and the requirement for a real-time online monitoring system of low-cost embedded equipment is met.

    本发明属轨道交通轨道检测技术领域,公开了一种在线检测钢轨波磨故障的方法。本发明的钢轨波磨故障检测方法,引入了对列车一侧4个测点钢轨波磨指标进行加权计算的方式,提高钢轨波磨评价指标的可靠性,有效避免了个别车轮状态异常造成的误判;引入了列车一侧4个测点钢轨波磨波长指标最大偏差是否小于偏差系数作为报警条件,有效避免了3至4个车轮均存在异常造成的误判。本发明的钢轨波磨故障检测方法监测结果准确且稳定,对系统性能要求小,满足低成本嵌入式设备实时在线监测系统的要求。
