The invention discloses a metro mileage positioning method based on double-sensor sensing time delay. Comprising the following steps: data acquisition, data preprocessing, track line identification and speed estimation based on double-compartment sensor sensing time delay, abnormal value processing is carried out by adopting an isolated forest algorithm, data fusion is carried out to determine whole-course speed estimation, and the whole-course speed estimation is integrated to obtain a mileage estimation value. The problem that positioning is inaccurate when the vehicle-mounted monitoring equipment detects track irregularity and disease positions is solved, subway operation and maintenance personnel can conveniently and rapidly determine track sections needing to be maintained and repaired, the maintenance efficiency is improved, the workload when the maintenance personnel find the positions to be maintained is greatly reduced, the cost is relatively low, and the method is suitable for popularization and application. Maintenance is simple and positioning precision is high.

    本发明公开了一种基于双传感器感知时延的地铁里程定位方法,包括如下步骤:数据采集、数据预处理、轨道线形识别和基于双车厢传感器感知时延的速度估计、采用孤立森林算法进行异常值处理、进行数据融合确定全程速度估计、将全程速度估计积分得到里程估计值。通过本发明解决了车载监测设备检测轨道不平顺、病害位置时定位不准确的问题,方便地铁运维人员快速确定需要进行保养维修的轨道区段,提高维修的效率,大幅降低维修人员寻找待维修位置时的工作量,成本相对较低,维护简单、定位精度高。
