城市轨道交通融合云平台探讨

Research on Fusion Cloud Platform of Urban Transit

针对现有条件下城市轨道交通系统存在的信息孤岛、设备分散、网络资源浪费、安全管控弱、运维体系失调等问题,结合云计算在城轨行业应用的政治环境、政府响应、技术环境、现象后的本质、内部推动力等方面,提出城市轨道交通融合云平台的方案。该方案基于线网化IT资源建设,为ISCS、ACC、CCTV、PIS等业务提供基于IaaS层服务,并伴有车站降级运行和异地热迁移等策略,提高了系统的可靠性和可用性,解决了IT基础设施统一化、线网化的相关问题。论述主要业务系统的部署要点和建议,如综合监控系统的主备切换、AFC的扁平化层级、CCTV的带宽计算、PIS系统软件的可移植性等方面。

This paper discusses problems such as islands information, scattered equipment, waste of network resources, weak security control, and the dissonance of operation and maintenance systems. An urban rail information platform is proposed based on cloud computing for the urban rail industry in terms of political environment, government response, technology environment, IT infrastructure construction for urban rail transit, internal driving force, etc. The scheme is based on line subnetted IT resource construction. The ISCS, ACC, CCTV, PIS, and other business providing services based on IaaS layers are accompanied by the station, degraded operation, different heat transfer strategies, and improvement in the reliability and availability of the system. The proposed platform solves the problem of unifying the IT infrastructure and network. The key points and suggestions of the main business system are discussed, such as the main standby switch of the integrated monitoring system, the flat level of AFC, the bandwidth calculation of CCTV, and the portability of PIS system software.
