Description

technical field [0001] The invention relates to a state monitoring system for a medium-speed maglev train. Background technique [0002] The medium-speed maglev train is a new type of urban transportation. It realizes the suspension and guidance of the train by controlling the suspension electromagnet, and provides traction power for the train through the linear motor. As a new type of transportation, maglev trains must meet high standards of safety and reliability to meet the requirements of commercial train operations in the future. During the operation of medium-speed maglev trains, the state of key components such as linear motors, electromagnets, and current collectors plays a vital role in the safe and stable operation of the train. Changsha Maglev and Beijing Maglev, which are now in operation, have not installed a train status monitoring system, and relevant data such as the operating status of the maglev train cannot be obtained. The train status can only be checke...

AI Technical Summary

Problems solved by technology

Changsha Maglev and Beijing Maglev, which are now in operation, have not installed a train status monitoring system, and relevant data such as the operating status of the maglev train cannot be obtained. The train status can only be checked and repaired after the train returns to the warehouse, which cannot adapt to the safety of the maglev train. Require

[0003] Due to the long-term operation of maglev trains in the current maglev lines, changes in line conditions and performance degradation of vehicle components will lead to increased vibration of linear motors, electromagnets and other components on maglev trains. The noise will reduce the comfort of the maglev vehicle. In severe cases, it will cause suspension instability and violent vibration, which will affect the safety of train operation.
