轨道交通融合通信及跨线切换研究
Research on Integrated Communication and Cross-Line Switching in Rail Transit
摘要
Abstract
Targeting at the problems of coexistence and non-interoperability of multiple types of wireless communication networks during cross-line operations in urban rail,and based on the requirements of train control,dispatching,monitoring and other key services in urban rail from the perspectives of communication continuity and reliability,this paper proposes an implementation method for the communication link continuity in the cross-line switching scenario.Through an integrated design of onboard wireless communication system for multiple types of wireless communication networks and the strategy planning for specific routing areas,the proposed method achieves the seamless switching between same type or different types of communication networks under the condition of non-interoperability of wireless communication networks of different urban rail lines,to ensure the reliable transmission of service data via appropriate wireless communication links.This method separates the communication layer from the service layer.The service layer becomes unaware of the coexistence and switching of multiple types of wireless communication networks,effectively reducing the complexity of communication network interconnection and switching during cross-line operations.This approach provides communication guarantee for cross-line operation of key services such as train control and dispatching at relatively low retrofitting cost,and has remarkable value for engineering application.关键词
