摘　　要：为解决传统ATS系统只能显示本线路的线路图、只能进行单一的线路行车调度指挥,以及物理硬件数量多、升级扩容难度大等问题,设计了一种基于云平台的城市轨道交通线网级列车监控系统(NATS)。该系统可以针对大型城市进行轨道交通全路网的信息显示,以便线网中心进行整体运营指挥和调度,提供行车指挥、运营指标分析、全局运行图编制、线网和线路协同指挥等运营管理功能,实现城市轨道交通监控调度集中化管理。借助于云平台,NATS系统能够虚拟化到云平台上,无需对系统本身进行大范围、深层次改动。利用云平台的特点,可以整合各线路的硬件资源,减少硬件设置,并根据NATS系统的规模灵活配置,便于既有线路数据迁移、后续线路接入和扩展,对系统整体性能有显著提升。本设计方案对各大城市的轨道交通线网级列车监控提供重要参考。The NATS system based on cloud platform is designed in order to solve the problems that the traditional ATS system can only display the route diagram of the corresponding line and can only carry out the traffic dispatching and command function of a single line,as well as the large number of physical hardware and the difficulties of upgrading and expanding capacity.The NATS system can display the information of the entire railway network for large cities,so that the network center can conduct overall operational command and dispatching.It provides operational management functions such as train operation command,operational indicator analysis,global operation diagram programming,and network and line coordination command,achieves centralized management of urban rail transit supervision and dispatching.With the help of the cloud platform,the NATS system can be virtualized onto the cloud platform without the need for large-scale and in-depth modifications to the system itself.By taking advantage of the characteristics of the cloud platform,it is possible to integrate the hardware resources of all lines,reduce the hardware quantity,and flexibly configure according to the scale of the NATS system,which facilitates the data migration of existing lines and the access and expansion of subsequent lines,and significantly improves the overall performance of the system.This design scheme provides an important reference for network automatic train supervision in large cities.
