In order to satisfy the complete vehicle type test requirements of maglev trains,main speed and position detection methods for maglev trains at home and abroad are reviewed and compared,including speed and position detection based on the inductive loop cable,speed and position detection based on sleeper tallies,speed and position detection based on Doppler radar,speed and position detection based on GNSS,speed and position detection based on teeth-slot detection of long stators and absolute position detection based on balise and pulse width coding. The applicability,advantages and disadvantages of each detection method are defined,methods of speed and position detection based on Doppler radar and GNSS are selected respectively to adapt to the type test based on comparison and analysis. The development tendency and research direction in the future are stated, including improvement of existing methods,development of novel methods and multi-sensor data fusion of speed and position detecting methods.
