Problems solved by technology

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
The sleeper counting method uses the sensor to count the running sleepers to achieve the purpose of positioning and speed measurement. Due to the constraints of the distance between the sleepers and the uneven spacing of the sleepers, its accuracy is low

Abstract

The invention relates to a speed measuring and positioning device for a magnetic levitation vehicle and a using method of the speed measuring and positioning device. The speed measuring and positioning device comprises racks mounted on a rail and vehicle-mounted inductive probes mounted on the magnetic levitation vehicle and in one-to-one correspondence with the racks in position, wherein the rackcomprises a mounting strip mounted on the rail and convex teeth arranged on the mounting strip, and the vehicle-mounted inductive probe detects the number of the convex teeth passing through within acertain period of time to achieve speed measurement and positioning of the magnetic levitation vehicle. The device further comprises a ground fixing plate installed on a ground track of the magneticlevitation vehicle, and the rack is arranged on the fixing plate. The device is simpler in structure, higher in precision and higher in practicability, the operation and calculation are very simple when the device is used for measuring the speed and the position of the magnetic levitation vehicle, and the measurement precision is high.

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a speed measuring and positioning 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 methods used in the research of medium and low speed maglev trains at home and abroad are the through-beam photoelectric switch detection method and the sleeper counting method. 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. The sleeper counting method uses the sensor to count the running sleepers to achieve the purpose of positioning and speed measurement. Due to the constraints of the distance between the sleepers and the uneven spacing o...
