Problems solved by technology

However, this kind of scheme is usually still independently aimed at the performance simulation of a certain subsystem in the train. For example, for the traction system in the maglev train, by constructing the traction control system, traction simulation system and traction simulation management subsystem, the traction control system realizes the traction simulation. The control of the converter and the linear motor in the system, and the data interaction with the traction simulation management subsystem, this kind of method cannot realize the performance simulation test of the whole train, and the semi-physical simulation method is used, and the output train characteristics are The virtual low-power signal, but the actual high-maglev motor has high-power characteristics, so it is impossible to truly simulate the high-power characteristics of the actual high-maglev motor. There will be differences between the simulation results and the actual physical performance, and it cannot truly reflect the performance of the train. , and a large amount of hardware in the platform uses simulators instead of real objects, which will also reduce the scope of system equipment testing and increase the risk of on-site debugging

The switch cabinet and the converter in the system circuit unit 12 are connected to control the state of the switch cabinet and the converter. The two-way traction system circuit unit 12 supplies power to the motor simulation unit 31, which can meet the performance simulation test under the double-terminal power supply mode of the high-speed maglev train.

[0081] It can be understood that in other embodiments, the traction system circuit unit 12 can also be multi-channel to simulate multiple-channel power supply modes, etc. Of course, simulation tests of other power supply modes can also be implemented by simply adju...

Description

technical field [0001] The invention relates to the technical field of high-speed maglev trains, in particular to a high-speed maglev train simulation test system and a test method. Background technique [0002] A maglev train is a train that uses electromagnetic force to suspend the train on the track and is propelled by the electromagnetic thrust of the linear motor. High-speed maglev train is a means of transportation that can fill the speed gap between high-speed rail and aircraft. The speed of high-speed maglev train can usually exceed 400 km / h. The high-speed maglev transportation system is composed of four subsystems: line track, traction power supply, operation control, and vehicle. Different from other rail transit systems, the various subsystems in the high-speed maglev transportation system are closely related to each other, that is, the high-speed maglev transportation system. It is a comprehensive system with close correlation and strong coupling correlation. ...
