A train speed adjusting method comprises the following steps: when satellite positioning speed measurement is effective, setting and calculating wheel/train speed ratio adjusting model parameters and train radar speed adjusting model parameters according to satellite positioning speed measurement data; when satellite positioning speed measurement is invalid, new train radar speed adjustment model parameters are calculated according to a given expression through the train radar speed adjustment model parameters obtained through previous setting, and wheel/train speed ratio adjustment model parameters are set and calculated through the adjusted radar speed adjustment model parameters; and then according to a wheel/vehicle speed ratio adjustment model, calculating train speed related quantities such as the train speed, the creep degree change rate, the creep degree and the train wheel set speed change rate. According to the method, the advantages of high satellite positioning speed measurement precision, good radar speed measurement real-time performance and long-time normal work are combined, and the accuracy and the reliability of measuring the speed related quantity of each train are improved.

    一种列车速度调整方法,在卫星定位测速有效时,由卫星定位测速数据整定推算轮/车速度比调整模型参数、列车雷达速度调整模型参数;在卫星定位测速无效时,由之前被整定得到的列车雷达速度调整模型参数依据给定表达式推算新的列车雷达速度调整模型参数,由调整后的雷达速度调整模型参数去整定推算轮/车速度比调整模型参数,然后依据轮/车速度比调整模型推算得到列车车速、蠕滑度变化率、蠕滑度和列车轮对速度变化率等各列车速度相关量。该方法结合了卫星定位测速精度高,雷达测速实时性好且能够长时段正常工作的优点,提高了测量各列车速度相关量的准确性与可靠性。
