Abstract

The invention relates to a position detection device for a maglev vehicle. The position detection device comprises a carrier signal probe, an iron core pulse probe and a vehicle-mounted rotor which are arranged on the maglev vehicle, and multiple sections of measurement assemblies which are sequentially arranged along a ground track. Each section of measuring assembly comprises a stator coil arranged on the track, a traction driving power supply connected with the stator coil in series, a carrier wave generating device connected with the traction driving power supply in parallel and matched with the carrier wave signal probe, and a stator iron core matched with the iron core pulse probe. The vehicle-mounted rotor is matched with the stator coil to drive the maglev vehicle to suspend and move. The device is simple in structure, reasonable in design, capable of being arranged in a segmented mode, capable of reducing cost, quite easy to operate and calculate when used for detecting the position of the maglev vehicle and high in measuring precision.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a position detection device for maglev vehicles and a method for using the same. Background technique [0002] The speed measurement and positioning system is an important part of the operation control of maglev trains. At present, the main method used in the research of medium and low speed maglev trains at home and abroad is to use the through-beam photoelectric switch method or the cross loop method to detect the position information of the maglev vehicle. Both need to continuously lay equipment or facilities along the ground track, and the construction cost is high. The through-beam photoelectric switch detection method uses a photoelectric sensor to detect the position and speed information of the maglev vehicle, which is easily disturbed by the external natural light environment and has poor reliability. Contents of the invention [0003] The purpose of the present invention...
