Title:
START CONTROL METHOD AND SYSTEM FOR MAGNETIC-LEVITATION TRAIN, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/083180
Kind Code:
A1
Abstract:
A start control method for a magnetic-levitation train. When a running speed is greater than or equal to a pre-set speed, and the direction of the running speed is consistent with a direction handle, or an output traction force of a train is the maximum output traction force, a brake release instruction is applied. Further disclosed is a start control system for a magnetic-levitation train, and a device and a storage medium, which are related to the implementation of the start control method. By means of the method, the phenomenon of a train sliding backwards is prevented, a running speed and a direction handle signal directly reflect the running state of the train on a ramp or other positions, and the method is more direct and reliable compared with the determination of a traction force; moreover, when the running speed and direction do not meet conditions, an output traction force of the train is increased gear by gear, thereby preventing the problem of a relatively large impulse caused by an excessive increase in the output traction force of the train; in addition, the discomfort of a passenger caused by an excessively large impact is prevented by means of the determination of a traction impact rate, and when the impact is excessively large, the traction impact rate is reduced by means of a delay, such that the impact or impulse is reduced, and the comfort of the passenger is improved.
