High-resolution positioning for maglev trains is implemented by detecting the tooth-slot structure of the long stator installed along the rail, but there are large joint gaps between long stator sections. When a positioning sensor is below a large joint gap, its positioning signal is invalidated, thus double-modular redundant positioning sensors are introduced into the system. This paper studie...

High-speed train tracing and an approach-alarming system is independent of the existing train control system, which uses the Global Navigation Satellite System and Integrated Location System for positioning to ensure the safety of trains and to prevent an accident of train collision caused by failure of the train control system. The system provides autonomous train tracing and positioning servi...

High precision positioning technology for a kind of high speed maglev train with an electromagnetic suspension (EMS) system is studied. At first, the basic structure and functions of the position sensor are introduced and some key techniques to enhance the positioning precision are designed. Then, in order to further improve the positioning signal quality and the fault-tolerant ability of the s...
