Research on location and speed detection for high speed maglev train based on long stator

Location and speed detection (LSD) is one of the key technologies of high speed maglev train. The traction system needs precise location and speed information to carry out the traction task of the train normally and reliably. Firstly, several conventional location and speed detection methods are introduced. And then, the method based on the tooth and slots of long stator is analyzed in detail. At last, a switch scheme is proposed to solve the long stator joint problem, the validity of which is proved by experiment.
