Embodiment Construction

[0051] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0052] Due to the influence of factors such as wheel-rail friction, it is difficult for existing traditional wheel-rail vehicles to develop to a higher speed. Generally speaking, 400km / h is the limit of its safety and cost. The application of maglev technology can free the train from the shackles of the wheel-rail relationship. When the maglev train is running, its wheels are suspended above the track. It is a new type of non-contact suspension, guidance and drive. It has better performance in terms of power, load, comfort and safety.

[0053] As a kind of maglev vehicle, superconducting maglev is composed of superconducting magnet, suspension frame, car body, car end connection, auxiliary power supply system, on-board electrical equipment, non-contact current receiving system and other systems. Among them, the on-board superconducting magnet is the most core sys...

Abstract

The embodiment of the invention discloses a train control method and a related device, and processing equipment can detect the vibration condition of a train in the vertical direction of a train rail in real time and obtain vibration information for reflecting the vibration condition. According to the vibration information, the processing equipment can determine the current rail repulsive force borne by the train, and the rail repulsive force is used for pushing the train to the upper portion in the vertical direction of the train rail. The processing equipment can determine electromagnetic force needed for stabilizing the train in the vertical direction of the train rail according to the rail repulsive force, and the electromagnetic force is used for pushing the train downwards in the vertical direction of the train rail. The processing equipment can adjust parameters of a current collection coil in the train according to the electromagnetic force, so that the train obtains the electromagnetic force to be balanced with the repulsive force of the rail, and the train is stable in the vertical direction of the train rail. The method can be realized only by adjusting the running parameters of the train, and a large number of devices do not need to be additionally arranged, so that the influence on the weight of the train body is low.

Description

technical field [0001] The present application relates to the technical field of maglev, in particular to a train control method and related devices. Background technique [0002] With the continuous advancement of technology, the way people travel is becoming more and more efficient and convenient. Among them, the maglev train is one of the fastest travel methods at present. [0003] In the related art, the maglev train relies on the magnetic force generated between the track and the train body to support the train body to suspend on the track for running. Because the car body of the maglev train is relatively light, and the magnetic resistance between the vehicle and the ground suspension system is very small, the train is easily affected by magnetic force and air resistance to generate vibration. [0004] The current train control method only has a stabilizing effect on the vibration of the train in the parallel direction of the track, and has poor control effect on the...
