The invention discloses a method for judging the slipping exiting working condition of a train based on speed measurement sensors. The method comprises the following steps that 1, the two same speed measurement sensors are arranged on the train; 2, after the train enters a slipping stage, the two speed measurement sensors periodically measure respective accelerated speeds respectively, the weight coefficient of the accelerated speeds of the two sensors in the previous period is calculated according to the accelerated speed measurement result in the previous period, and the fusion filtering accelerated speed in the current period is calculated according to the accelerated speed and the weight coefficient; and step 3, judging whether the train exits the slip working condition or not according to the weight coefficient and the fusion filtering acceleration. According to the method, the correctness of the vehicle-mounted signal system for judging that the train exits from the slip working condition is improved, and the safety of train speed calculation and position calculation is improved.

    本发明公开了一种基于测速传感器的列车退出打滑工况判定方法,包括以下步骤:步骤1,在列车上设置两个相同的测速传感器;步骤2,列车进入打滑阶段后,两个测速传感器分别周期性测量各自的加速度,通过前一个周期的加速度测量结果计算前一个周期两个传感器的加速度的权重系数,并根据加速度和权重系数计算当前周期的融合滤波加速度;步骤3,根据权重系数和融合滤波加速度判断列车是否退出打滑工况。本发明提高了车载信号系统判定列车退出打滑工况的正确性,提高了列车速度计算和位置计算的安全性。
