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 method for using the same, comprising a rack installed on a track, and an on-board induction probe installed on the magnetic levitation vehicle and corresponding to the position of the rack one by one; the rack includes a The installation strip on the track, and the convex teeth arranged on the installation strip, the vehicle-mounted induction probe realizes the speed measurement and positioning of the magnetic levitation vehicle by detecting the number of convex teeth passing through within a certain period of time; it also includes installation on the ground track of the magnetic suspension vehicle The ground fixed plate, the rack is arranged on the fixed plate. The device has simpler structure, higher precision and more practicability. Using the device to measure the speed and position of the maglev vehicle is very simple to operate and calculate, and has high measurement precision.

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...
