Problems solved by technology
[0004] However, in the current test method, one is to directly set the parameters during the high-speed maglev operation process in the partition radio control unit and the vehicle-mounted radio control unit to realize the test of the high-speed maglev positioning and speed measurement system, which lacks authenticity , may lead to inaccurate test data
The other is to modify the control program of the traction motor controller, change the actual interface of the traction motor controller to an Ethernet interface, and send the parameters of the high-speed magnetic levitation positioning speed measurement system in the simulator to the traction motor controller in the form of Ethernet , because the communication interface in the real scene cannot be simulated, not only the timeliness is low, but also the test data may not be applicable to the actual application

Description
Technical field [0001] Example relates to the field of rail transportation present application, particularly, to a test system and test method thereof. Background technique [0002] High-speed maglev speed positioning system is a high-speed maglev train an essential part of a high-speed positioning speed maglev train system can provide location information for the traction system to provide mileage information for the transportation control system and provide diagnostic information to on-board security computer. Thus, positioning accuracy and the positioning speed maglev system stability is directly related to the safe operation of the train. [0003] Since it is difficult to complete the test Maglev high-speed verification process in the physical system ground, and therefore, in order to test the stability of the positioning accuracy and the positioning speed maglev system, need to transfer data during operation of the maglev system and a traction control operation to supply the...
