Technology Analysis of EMS High-Speed Maglev System

The EMS-type high-speed maglev system consists of four major components, including maglev line, vehicle system, propulsion and power supply system, and operation control system. The maglev line is one of the main components of the maglev train that utilizes electromagnetic force to achieve support and guidance functions. The vehicle system is a complex system that includes several subsystems, including the vehicle body, maglev bogie, levitation and guidance, power supply, operation control and fault diagnosis, safety brake, and positioning speed measurement. Among them, the levitation and guidance system provide the levitation and guidance functions for the maglev train to achieve its safe and reliable operation. Taking the EMS-type high-speed maglev system as the object, this chapter analyzes the basic components of maglev line, vehicle system, propulsion and power supply system, and operation control system in the high-speed maglev transit system; gives the basic structure of the high-speed maglev vehicle system, analyzes the functional characteristics of components of the high-speed maglev vehicle system; focuses on the basic structure, technical requirements and control scheme of the levitation and guidance system of the high-speed maglev train, respectively.
