Maglev train dynamic performance test system

Abstract

The invention discloses a maglev train dynamic performance test system. In the system, a traction converter is used for converting a direct current into an alternating current so as to provide power for a maglev train; a positioning information acquisition device is used for acquiring relative position information and absolute position information of the maglev train and transmitting the relativeposition information and the absolute position information to a communication device; the communication device is used for transmitting the relative position information and the absolute position information to the traction converter device, and therefore the the traction converter adjusts the speed of the maglev train according to the relative position information and the absolute position information; a control device is used for controlling the maglev train to run in the test track and testing the dynamic performance of the maglev train. By adopting the test system, the dynamic performanceof the maglev train can be tested before the maglev train is debugged on line. The probability that the maglev train goes wrong after going online due to the fact that the maglev train is not subjected to dynamic testing is reduced, the maintenance efficiency of the maglev train is improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a dynamic performance testing system for a maglev train. Background technique [0002] The maglev train is a new type of vehicle that uses electromagnetic force to suspend the car body above the track with a given gap and is driven by a linear motor. After the maglev train is assembled and completed, the maglev train needs to be tested. [0003] At present, before the maglev train goes online for debugging, the static performance of the maglev train can only be tested because the train does not actually run on the track, and the dynamic performance needs to be debugged after it goes online. However, when the dynamic performance is tested after going online, problems such as the failure of the maglev train to levitate, the mismatch between the phase sequence of the traction and the phase sequence of the levitation magnet, failure of communication between different interfaces...

AI Technical Summary

Problems solved by technology

However, when the dynamic performance is tested after going online, problems such as the failure of the maglev train to levitate, the mismatch between the traction phase sequence and the levitation magnet phase sequence, failure of communication between different interfaces, and errors in the traction / braking control logic are prone to occur.

[0004] When at least one of the above problems occurs, the maglev train cannot continue to float above the track with a given gap, and needs to stop on the spot and wait for maintenance

The maglev train cannot occupy the running track for a long time, and there may be no maintenance tools near the running track. It is necessary to tow the maglev train from the fault location to the maintenance site, resulting in low maintenance efficiency and high maintenance costs.
