摘　　要：在高速磁悬浮列车中,定位传感器是测定列车位置的关键器件,其信号正常与否直接影响列车的运行效果。针对定位传感器应用中相角和齿槽数信号异常的问题,利用硬件冗余和差分法进行时间序列预测,解决了该类问题。实际应用证明:该方法满足列车运行要求。In the high-speed maglev train,the position sensor plays the crucial role in measuring the position of the train, but the signal directly affects the run effect of the train. Aiming at the abnormity of the phase and groove number, hardware redundancy and difference method is used to forecast time series and the problems are resolved. Actual application shows that the method can neet the needs of the high-speed maglev train.
