Train-mounted control system of high-speed maglev train

Abstract

The invention provides a train-mounted control system of a high-speed maglev train, which is characterized in that a driving coil and a Hall sensor proximity switch 4 are arranged on a track, and the Hall sensor proximity switch controls the on or off of the driving coil 8; a train-mounted permanent magnet or a train control electromagnetic coil is arranged at the position, corresponding to the Hall sensor proximity switch, of the bottom of the train to serve as a train-mounted control system, the train-mounted control system can directly control the drive coil in a non-contact mode through the Hall sensor proximity switch, and direct control over the drive coil on the track by the train is achieved. The defect that an existing control system needs to be provided with branch power stations at intervals is overcome, and the structure of the control system is simpler and more reliable.

[0003] The typical electromagnetic levitation trains that have been put into commercial operation are Germany’s EMS electromagnetic levitation system and Japan’s EDS superconducting electric levitation train, both of which use synchronous linear motor traction drive technology, and the control system of synchronous linear motors that control train running is relatively complicated , the obvious problem is that two trains in the same driving section can only be controlled by the same control system, and it is impossible for two trains that are about to collide to avoid running in opposite directions. It is difficult to avoid two-vehicle collisions in the same driving section

The power system and control system that control the train's running are on the track. The train and the track need to collect sensors for the relative displacement between the train and the track. It also requires a set of very complex algorithms and computing equipment, and even requires remote control technology to transmit the train. The communication signals with the control system on the track make the structure of the control system very complex, and there are too many control links, which makes the reliability fragile. The complex control system restricts the development of maglev trains
