Research on Urban Railway Train Control System Supporting Multi-network Integration
Research purposes:The urban railway is a rail transit system that is suitable for connecting the central urban area of the metropolitan area with the surrounding urban clusters,providing public transportation,large volume,fast and convenient transportation services.As the link between trunk railway,intercity railway and urban rail transit,urban railway train control system should be compatible with CTCS system and CBTC system,support the trains to cross line without stop between CTCS and CBTC lines,promote the"four networks integration"of trunk railway network,intercity railway network,urban railway network and urban rail transit network,realize the interconnection of rail transit network,improve the overall regional transport capacity and improve the quality of passenger service.Research conclusions:(1)It is suggested that CTCS and CBTC should set overlapping areas,and the ground equipment of the two systems should be added with interfaces to support train cross-line operation.(2)It is recommended to develop on-board equipment compatible with CTCS and CBTC,and adapt the ground equipment of CTCS line and CBTC line through on-board equipment to support cross-line operation.(3)For projects with tight construction schedules and sufficient vehicle installation space,split type on-board equipment can be used,which is mature,reliable,and easy to develop and implement.(4)For projects with a relaxed construction period and limited vehicle installation space,integrated on-board equipment can be used,which has high system integration,saves costs,and is easy to install.(5)The results of this study can provide reference and inspiration for the system development,engineering design,and construction implementation of urban railway signal systems with CTCS and CBTC cross-line operations.
