Scheme Research on Train Operation Control System Supporting Virtual Marshalling Technology

Abstract

Objective With the development of urban rail transit network, the uneven temporal and spatial distribution characteristic of the network passenger flow is growing prominent, and it is difficult to achieve the "on-demand transportation " with the existing fixed marshalling train. In order to make full use of the line capacity, it is necessary to study a new generation of train operation control system. Method A design scheme of train operation control system supporting virtual marshalling technology is proposed, and the performance difference between the train operation control system supporting virtual marshalling technology and the traditional one is analyzed from aspects of train operation logic control, line resource management and dispatching command mechanism. The key technology of virtual marshalling is introduced. In order to realize the application of virtual marshalling technology in engineering projects, the engineering design that needs to be considered in project planning and design stage for virtual marshalling train parking area, main line platform area and platform door interface are proposed. Result & Conclusion The vehicle-to-vehicle communication architecture provides a more reasonable system architecture design basis for realizing virtual marshalling technology. The train operation control based on "collision soft wall" model collaborative control and intelligent perception is the key technology in virtual marshalling train operation control system. With the extensive application of virtual marshalling technology, train operation control system can quickly adjust the online train length when the passenger flow changes, improving the flexibility of transportation organization and the passenger service level.
