Abstract: This paper introduced the composition and principle of the high-speed maglev operation control system with a speed of 600 km/h, and studied the scheme that the operation control system completed track control, train control and traction control under the cooperation of other systems, and described interfaces and control contents between the operation control system and other systems. Combined with the functions of the operation control system, it further showed that the operation control of 600 km/h high-speed maglev train needed the cooperation of other systems. The results show that the operation control system is one of the key systems of high-speed maglev train. The control of high-speed maglev train also needs the cooperation of traction control system, vehicle system and other systems.
