The invention relates to the technical field of railways, and provides a train speed calculation method, system and device and a medium, and the method comprises the steps: in the acceleration or deceleration stage of a train, continuously collecting the train speed for N times by using an axle sensor and a radar sensor; calculating a first speed difference V wheel of the train at the front moment and the rear moment and a corresponding acceleration or deceleration based on data acquired by a wheel shaft sensor; according to radar sensor data, a second speed difference Vlightning is calculated, and when N is larger than Nmin and smaller than Nmax, the calculated accelerated speed of the train is continuously larger than the maximum accelerated speed of the locomotive, or the deceleration is continuously larger than the minimum accelerated speed of the locomotive, and meanwhile the difference value between the V wheel and the Vlightning continuously exceeds the threshold value, it is judged that the train idles or skates; and if the situation occurs, the sum of the speed at the previous moment and the Vthunder serves as the current running speed of the train. According to the method, the influence of idle roller skating on train speed calculation can be reduced.

    本公开涉及铁路技术领域,提供了一种列车速度的计算方法、系统、设备及介质,所述方法包括在列车加速或减速阶段,利用轮轴传感器和雷达传感器,持续采集列车速度N次;基于轮轴传感器采集的数据,算出列车前后两时刻的第一速度差△V轮,以及对应的加速度或减速度;依据雷达传感器数据,算出第二速度差△V雷,当Nmin<N<Nmax,且计算出的列车加速度持续大于机车最大加速度,或减速度持续大于机车最小加速度,同时△V轮与△V雷的差值持续超出阈值时,判定列车出现空转或轮滑;若出现此类情况,将前一时刻速度与△V雷之和作为列车当前运行速度。本发明能够降低发生空转轮滑对计算列车速度的影响。
