The invention discloses an early warning method and device for sleeper empty hoisting damage, and the method comprises the steps: obtaining the wheel rail vertical force data of a railway vehicle in a detection line range, carrying out the low-pass filtering processing of the wheel rail vertical force data, and obtaining the low-frequency wheel rail vertical force data; dividing the detection line into a plurality of evaluation units according to a preset length, and determining the maximum value of the vertical force data of the low-frequency wheel track in each evaluation unit; sequentially comparing the maximum value of the low-frequency wheel-rail vertical force data of each evaluation unit with a preset evaluation peak value, and screening out the evaluation units of which the maximum values of the low-frequency wheel-rail vertical force data are greater than the preset evaluation peak value; combining the screened evaluation units; and comparing the combined total length of the evaluation units with a preset length, and if the combined total length of the evaluation units is greater than the preset length, sending out empty hoisting early warning information. The method can timely discover the wheel rail diseases, improves the disease treatment efficiency, and guarantees the operation safety of the vehicle.
本发明公开了一种轨枕空吊病害的预警方法及装置,其中该方法包括:在检测线路范围内,获取轨道车辆的轮轨垂向力数据,对轮轨垂向力数据进行低通滤波处理,得到低频轮轨垂向力数据;将检测线路按照预设长度划分为多个评价单元,确定每一个评价单元中低频轮轨垂向力数据的最大值;依次将每一个评价单元的低频轮轨垂向力数据的最大值与预设评价峰值进行比对,筛选出低频轮轨垂向力数据的最大值大于预设评价峰值的评价单元;将筛选出的评价单元进行合并;将合并后的评价单元总长度与预设长度进行比对,若合并后的评价单元总长度大于预设长度,发出空吊预警信息。本发明可以及时发现轮轨病害情况,提高病害整治效率,保障车辆运行安全。
