The invention belongs to the technical field of rail train fault detection, and discloses a method for monitoring polygon faults of train wheels on line. According to the vehicle wheel polygon fault monitoring method, a mode of taking the average value of the polygon indexes within a certain time as the polygon evaluation index and a mode of selecting the polygon order index appearing for the most times within a certain time as the polygon order evaluation index are introduced, so that the evaluation indexes are stable and reliable, and misdiagnosis and missed diagnosis are effectively avoided; the vehicle speed is introduced as a condition for fault judgment and alarm state output, and a method for time dimension judgment and fault state value counting judgment is introduced, so that the influence of the rail state on the judgment of the polygonal fault state of the wheel is effectively avoided, and the interference of a large amount of fault alarm information prompts on a driver and passengers is reduced. The detection method for the polygon fault of the wheel is accurate and stable in monitoring result, low in requirement for system performance and capable of meeting the requirement for a real-time online monitoring system of low-cost embedded equipment.

    本发明属于轨道列车故障检测技术领域,公开了一种在线监测列车车轮多边形故障的方法。本发明的车轮多边形故障监测方法,引入了一定时间内多边形指标平均值作为多边形评价指标的方式和选取一定时间内出现最多次的多边形阶次指标作为多边形阶次评价指标的方式,保证了评价指标稳定可靠,有效避免了误诊和漏诊;引入了车速作为故障判断和报警状态输出的条件,引入了时间维度判断和故障状态值计数判断的方法,有效避免了轨道状态对车轮多边形故障状态判断的影响,减少了大量故障报警信息提示对驾乘人员的干扰。本发明的车轮多边形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。
