Study on Multi-Network Integration System of Urban Rail Train based on Real-Time Ethernet

基于大带宽、高实时的以太网构建覆盖全列车的列车网络控制系统(TCMS),结合信息安全防护技术,将传统TCMS网络与列控系统专用网络予以合并,实现控制网、维护网、列控网、制动网的多网融合。设计方案突破了系统间网络融合、信息安全等关键技术,有效减少了列车线缆铺设,优化了车载网络布局及各子系统间接口,提升了系统响应的实时性,降低了系统复杂度,使得维护简易化、组网更便捷,有利于提高列车性能和可靠性,也有利于基于统一平台对列车进行管理、控制和维护,推进列车的智能化。

The train network control system(TCMS)covering the whole train is built based on large bandwidth and high real-time Ethernet,and combined with information security protection technology,the traditional TCMS network and the special network of train control system are merged to realize the multi-network integration of control network,maintenance network,train control network and brake network.The design solution breaks through the key technologies of inter-system network convergence and information security,effectively reduces the laying of train cables,optimizes the layout of the on-board network and the interfaces between sub-systems.it improves the real-time response of the system,reduces the complexity of the system and makes the maintenance simpler and the network more convenient,and it can help to improvetrain performance and reliability,and facilitates ethe management,control and maintenance of trains based on a unified platform and promoting train intelligence.
