摘要

The paper designs an integrated positioning architecture by coded odometer and Doppler radar and analyzes their error sources. Confidence interval of train safety positioning is identified based on the analysis. Kalman filter is used to diagnose abnormal output from coded odometer and Doppler radar. Safety comparator is used to identify the reliability of confidence interval. The experimental results show that the proposed method can effectively keep the efficiency and safety of train positioning when the train is in slipping state.
