On-line state monitoring system for medium speed maglev train

Abstract

The invention discloses an on-line state monitoring system for a medium speed maglev train,which comprises a temperature monitoring subsystem,a vibration monitoring subsystem and a current monitoringsubsystem; the whole monitoring system comprises a vibration sensor,a temperature sensor,a vibration collector,a temperature transmitter,a vehicle host and a vehicle-ground communication device,a cable; the system is divided into vehicle-mounted equipment and ground equipment,wherein the vehicle host in the vehicle-mounted equipment is respectively connected with the communication equipment,the vibration collector and the temperature transmitter; the ground equipment comprises a suspension frame vibration sensor,a linear motor vibration sensor; a current collector vibration sensor,a suspensionelectromagnet temperature sensor,a linear motor temperature sensor and a current collector temperature sensor. According to the invention,the running state monitoring of the key components of the medium speed maglev train,such as the linear motor,the electromagnet and the current collector,is monitored,the running state of each key component is intelligently analyzed and evaluated,and a basis forguiding the operation and maintenance and the optimization design of the train is provided.

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...

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
