摘要
云计算技术已被广泛应用于城市轨道交通生产系统的集成与融合。针对目前集中式云平台建设模式存在网络传输负载高、网络延迟、数据中心规模庞大等问题,提出优化设计思想,搭建具有边缘层、基础层、平台层和应用层等4层总体架构的新一代城轨生产系统融合平台,通过边缘计算和云计算的紧密协同,提高城轨生产系统的实时性,有效控制线网主、备数据中心的建设规模,且便于智慧化应用的开发和部署。最后,提出分步分阶段的落地方案和典型应用实例。
Cloud computing has been extensively used in the integration and fusion of urban rail transit automation systems.The existing centralized cloud platform construction is associated with some issues,such as high network load,long userperceived latency,and large data-center scale.This paper optimizes and constructs the four-layer architecture of a new generation fusion platform with an edge,foundation,platform,and application layers.Through the cooperation of edge-cloud computing,real-time performance is improved and the scale of IDC(internet data centers)is controlled.The process is conducive to the development of intelligent applications.This paper introduces typical application examples in a step-by-step manner.
