A locomotive speed measuring and adjusting device is characterized in that when satellite positioning speed measurement is effective, wheel/vehicle speed ratio adjusting model parameters and locomotive radar speed adjusting model parameters are set and calculated according to satellite positioning speed measurement data; when satellite positioning speed measurement is invalid, new model parameters are calculated according to the previous model parameters; and the locomotive speed is calculated according to model parameters. Meanwhile, whether the locomotive is in a variable-speed motion state or not is automatically judged to carry out optimization calculation on satellite positioning data transmission time, namely the delay interval period number, so that the accurate delay interval period number is obtained, and the accuracy and reliability of locomotive speed calculation are further guaranteed.
一种机车速度测量调整装置,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、机车雷达速度调整模型参数;在卫星定位测速无效时,由之前模型参数推算新的模型参数;再依据模型参数推算得到机车速度。同时,还自动判断机车是否处于变速运动状态进行卫星定位数据传输时间,即延滞间隔周期数的优化计算,以得到准确的延滞间隔周期数,进一步保证了前述机车速度推算的准确性与可靠性。
