The invention discloses a rail transit vehicle-line coupling operation and maintenance method and system. The method comprises the following steps: judging whether a stability index, a comfort index and framework stability data of a rail vehicle are normal or not in real time; if any data is abnormal, wheel set geometric dimension data and track line irregularity detection data of the railway vehicle are obtained, vehicle-line coupling analysis is carried out, and abnormity positioning is achieved; wherein the vehicle-line coupling analysis specifically comprises the following steps: calculating the equivalent conicity of the same wheel set when the same wheel set passes through different road sections of the track line, and if the equivalent conicity is abnormal in the different road sections, indicating that the wheel set is abnormal; and calculating the equivalent conicity when different wheel sets pass through the same road section, and if the equivalent conicity is abnormal, indicating that the road section is abnormal. According to the method, abnormal problems can be accurately positioned and timely corrected, data support is provided for operation and maintenance of a rail transit system, and safe and efficient operation of rail transit vehicles is guaranteed.

    本发明公开了一种轨道交通车‑线耦合运维方法及系统,方法包括:实时判断轨道车辆的平稳性指标、舒适度指标以及构架稳定性数据是否正常;若任一数据不正常,获取轨道车辆的轮对几何尺寸数据和轨道线路不平顺检测数据,进行车辆‑线路耦合分析,实现异常定位;其中,进行车辆‑线路耦合分析,具体为:计算同一轮对在通过轨道线路不同路段时的等效锥度,若等效锥度在不同路段均出现异常,则表明该轮对出现异常;计算不同轮对通过同一路段时的等效锥度,若等效锥度均出现异常,则表明该路段出现异常。本发明能够对异常问题进行精确定位,及时修正问题,为轨道交通系统运维提供数据支撑,保障轨道交通车辆安全、高效的运营。
