Description

TECHNICAL FIELD

[0001] The present application relates to the field of super high-speed maglev traction control technology, and particularly relates to a semi-physical simulation platform suitable for super high-speed maglev. BACKGROUND

[0002] With the development of rail transit, the running speed and transport capacity of traditional rail transit cannot meet the increasing social demand. Super high-speed maglev trains have attracted widespread attention due to their advantages in high-speed operation. The running speed of super high-speed maglev trains exceeds 1000 km / h, and the suspension propulsion technology is the "core technology" of the power system, which is particularly critical.

[0003] When the super high-speed maglev train runs on the track, the ground traction converter supplies power to the stator section of the linear motor and generates a traveling wave magnetic field, which drives the train to run. The traction control system adjusts the output voltage of the converter according to the current running state of the train, and the switch controller controls the opening and closing of the trackside switch station along the line according to the current position of the train combined with the step change strategy, controls the frequency, phase and amplitude of the current output to the stator section of the linear motor, and makes the train run according to the planned trajectory.

[0004] At present, the semi-physical simulation technology has become a common solution in the modern industrial field due to its characteristics of significantly reducing development cost and shortening development cycle. The semi-physical simulation can make the actual device execute various operating conditions through the establishment of a virtual test environment, improve the test coverage, and verify the product requirements.

[0005] The prior art proposes a semi-physical simulation platform for high-speed maglev trains, in which the connection of the traction control system and the simulation machine device is limited to the converter control unit. However, in actual maglev train operation, the entire train operation work needs to be completed by the cooperation of multiple systems. The communication between the systems and the action execution of the control strategy of the system in response to different working conditions will ultimately affect the operation of the train. The interface between the actual device and the simulation device only has an optical-electric conversion module, which cannot meet the complex interface requirements of actual needs. The control instructions of the train are lacking, and in actual application, not only the control of the ground equipment is needed, but also the execution of certain control instructions by the train body.
