High speed magnetic suspension train travel control system

Abstract

The high speed magnetic suspension train operation control system includes central system in the control center, divisional systems in the stations and transformer stations beside rail, and vehicular systems on trains. The central system includes control system, fault diagnosing system and operation simulating system with safety computer system to raise the safety and the efficiency magnetic suspension train system. The divisional system consists of divisional safety control and managing system, drive control and speed limiting system, switch control system and powering and measuring system, and has modular safety computer. The vehicular system has two independent safety control and speed limiting systems for raised reliability. All the systems are connected via radio or wired communication network.

Description

technical field [0001] The invention relates to an operation control system of a high-speed maglev train, which belongs to the field of rail transit system control. Background technique [0002] The high-speed maglev train system consists of four parts: vehicle system, line system, train propulsion system and operation control system. The high-speed maglev train operation control system is the center of the high-speed maglev train system. The system connects the vehicle system, line system, and train propulsion system to complete the operation command control and safety protection functions of the high-speed maglev train system. [0003] Although Japan's high-speed maglev train system has entered the engineering test stage, and Germany's high-speed maglev train system has reached the level of commercial application, the research work on the high-speed maglev train operation control system and its integration methods is still lagging behind, and is still in the theoretical re...

Problems solved by technology

[0023] 3) The setting and function definition of the partition control computer of the German high-speed maglev train operation control system and its relationship with the partition safety computer are unreasonable. The partition control computer processes data closely related to safety and performs functions closely related to safety. However, the partition security computer is required to implement security checks. From the structural relationship between the partition control computer and the partition security computer, it is not difficult to see that the unreasonable relationship between software and hardware increases the complexity of the software and reduces the security and availability of the system;

[0024] 4) The divisional operation control system of Germany's high-speed maglev train operation control system is the core of the operation control system and the key to the safety of the operation control system. Almost all the information processed by the divisions is closely related to safety. The Shanghai Maglev Demonstration Line The partition control computer is a hot standby non-safety computer. The partition control computer uses a non-safety computer to handle a large number of security-related events. Although the partition security computer has been protected to a certain extent, there are still security holes, which reduces the system security;

[0025] 5) In the on-board operation control system of the high-speed maglev train operation control system in Germany, the safety computer system structure and function of the head car and the tail car do not constitute a real hot backup system. There is only one set in the German system of the Shanghai Maglev Demonstration Line The on-board safety computer system is directly connected to the vehicle-ground wireless communication system. Due to structural limitations, only one on-board safety computer system has complete operation command and safety protection functions, and the other on-board safety computer system only has a small part of safe parking. function, without complete operation command and safety protection functions, and does not constitute a real hot backup system, which reduces the reliability and availability of the system;

[0026] 6) The central operation control system has a safety confirmation function to a certain extent. The central operation control system of the high-speed maglev train operation control system in Germany is composed of non-safety computers, which reduces the safety of the system
