Abstract :
The position detection technology for the low speed maglev train test line in Tangshan is studied based on the inductive looped-cable. It could provide accurate position information as the maglev train´s inlet parking. The paper introduces the functionality of the system, and uses the two on-board coils to receive signal. By doing the signal division operation, the measurement error caused by the shaking or vibration is inhibited to a certain extent. The impedance characteristics of the loop-cable on track and the on-board coil are analyzed and two different impedance matching methods are adopted. Finally, the system implementation and experiment results are given, which shows that the system could meet the requirement for the maglev train´s inlet parking.
