Maglev train and braking control system and method thereof

Abstract

The invention discloses a braking control method for a maglev train. The braking control method comprises the steps that the maximum electric braking force A is applied according to a received braking instruction; required electric braking force B obtained by the braking instruction is acquired; and whether the maximum electric braking force A is smaller than the required electric braking force B or not is judged, if yes, electric braking continues being carried out according to the maximum electric braking force A, and if no, electric braking is carried out according to the required electric braking force B. The invention further discloses a braking control system for the maglev train and the maglev train comprising the braking control system. According to the braking control method, the problems that according to an existing method, the braking response time is long, and electric braking is not fully utilized can be solved, the braking response time and the braking distance can be shortened, the advantages of electric braking is given to maximum play, accordingly the safety of the system is improved, and the problems of high energy consumption and high maintenance cost are solved.

Description

technical field [0001] The invention relates to the technical field of maglev trains, in particular to a maglev train and its braking control system and method. Background technique [0002] At present, the medium and low-speed maglev trains developed in China adopt the long-leading-short stator mode, relying on electromagnetic attraction to levitate the vehicle to a certain height, so that there is no mechanical contact between the vehicle and the ground track, and the guiding force is generated by the electromagnetic attraction, and the traction force generated by the linear motor Driving the train to run fundamentally overcomes the limitation of wheel-rail train adhesion. The brake system controlled by microcomputer is composed of friction brake and electric brake together to form a complete brake system, and the electric brake is given priority to give full play to the advantages of electric brake. The electric brake is composed of linear motor regenerative brake and ele...
