The invention discloses a train multi-source fusion sensing system-based wheel diameter dynamic correction method, which comprises the following steps of: in a train cruising stage, selecting a period of time T; within the time T, the fusion mileage L1 and the speed transmission L2 of the train are measured through the multi-source sensing device and the speed transmission device respectively, and the corrected diameter Dg of the train wheels is obtained based on the comparison error of the fusion mileage L1 and the speed transmission L2; the method for measuring the fusion mileage L1 of the train through the multi-source sensing equipment comprises the following steps: step 1, acquiring observation data of various sensors of the train; step 2, carrying out time registration on observation data of various sensors; step 3, performing outlier elimination on each observation data after time registration; and step 4, distributing different weights to the observation data after local filtering, then carrying out federated filtering, and outputting a fusion result. According to the method, the deployment of entity beacons is greatly reduced, the limitation of fixed installation position requirements is avoided, the calibration opportunity is flexible and highly selective, the wheel diameter parameters can be corrected at any time, and the calibration precision is high.

    本发明公开了一种基于列车多源融合感知系统的轮径动态校正方法,包括:在列车巡航阶段,选取一段时间T;在时间T内,分别通过多源感知设备和速传设备测量出列车的融合里程L1和速传L2,基于融合里程L1和速传L2的比较误差得出列车轮的修正直径Dg;通过多源感知设备测量列车的融合里程L1的步骤包括,步骤一,获取列车多种传感器的观测数据;步骤二,对多种传感器的观测数据进行时间配准;步骤三,对时间配准后的各观测数据进行野值剔除;步骤四,局部滤波后各观测数据分配不同权重后进行联邦滤波,输出融合结果。本发明大大减少了实体信标部署,无固定安装位置要求限制,校准时机灵活选择性强,可随时对轮径参数修正,校准精度高。
