Onboard control system of high-speed maglev train

Abstract

The present invention provides an onboard control system of a high-speed maglev train. The onboard control system of the high-speed maglev train is characterized in that drive coils and Hall sensor proximity switches 4 are provided on a track, the drive coils 8 are controlled by the Hall sensor proximity switches to be connected or disconnected, the bottom of the train is provided with onboard permanent magnets or vehicle control solenoid coils as the onboard control system at the positions corresponding to the Hall sensor proximity switches, the onboard control system can directly control the drive coils in a contactless way through the Hall sensor proximity switches, so that the train can directly control the drive coils on the track, the defect that substations are required to be arranged at intervals in the traditional control system can be overcome, and the control system is more simple and reliable in structure.

[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
