Study on Train Location Method with Multi-sensor Information Fusion
Cao Chang-hong · Machinery & Electronics · 2011
Due to using single sensor is difficult to achieve high accuracy and reliability in train location system.So in the paper the method of train location based on multi-sensor information fusion is proposed.This paper introduces the structure of multi-sensor information fusion and sets up mathematical model of federated kalman filting.Then the INS/GPS/DVS integrated navigation system is simulated with Matlab.Computer simulation results show that,multi-sensor information fusion can improve accuracy and reliability of the train location,which is more suitable for train location in the train rail traffic.
