Optimal Design of the Absolute Positioning Sensor for a High-Speed Maglev Train and Research on Its Fault Diagnosis
This paper studies an absolute positioning sensor for a high-speed maglev train and its fault diagnosis method. The absolute positioning sensor is an important sensor for the high-speed maglev train to accomplish its synchronous traction. It is used to calibrate the error of the relative positioning sensor which is used to provide the magnetic phase signal. On the basis of the analysis for the ...
متن کاملStudy on Absolute Positioning Technique for Medium-Low Speed Maglev Train Based on Cross Coding Inductive Loop Wire
During recent years, the medium-low speed maglev system brings new chances for the development of maglev train related techniques, and traditional operation and control standards have been applied in its signal system design. However, as there are no wheel sets on maglev train, the positioning function cannot be realized by the corresponding method in wheel-rail based urban rail transit. Many r...

Broadband internet and wireless network environments which have made considerable progress in recent years offer many opportunities to deliver and to exchange information. The fair uses o...
متن کاملSwitching Algorithm for Maglev Train Double-Modular Redundant Positioning Sensors
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...
