摘要
本文结合城市轨道交通网络化发展需求,研究国内外现有AFC系统的不足,结合主流的AFC系统架构研究热点,深入分析了AFC数据信息流和云平台的功能和非功能需求,通过引入云计算技术优化传统五层AFC系统架构,提出构建基于私有云平台的AFC系统融合架构方案。架构中提出通过私有云平台替代传统AFC系统中的ACC层和LC层,不再在SC层设置数据存储和计算资源,并通过云平台实现统一监控与管理。本文提出的私有云平台AFC架构体系,让车站终端设备直接受控于私有云平台,减少车站及线路系统中间收发环节,有助于应对大客流的常态化,解决海量数据的计算与存储等问题,并能满足全局性运营数据的管理需要。
Combined with the development needs of urban rail transit network, this paper studies the short-comings of the existing AFC system at home and abroad. Combined with the mainstream AFC system architecture research hotspots, it deeply analyzes the functional and non-functional requirements of AFC data and information flow and cloud platform. By introducing cloud computing technology to optimize the traditional five-tier AFC system architecture, it proposes to build a fusion architecture of AFC system based on private cloud platform. In the architecture, the ACC layer and LC layer in the traditional AFC system are replaced by the private cloud platform, and the data storage and computing resources are no longer set in the SC layer, and the unified monitoring and management are realized through the cloud platform. The AFC architecture of the private cloud platform proposed in this paper makes the terminal equipment of the station directly controlled by the private cloud platform, reduces the intermediate receiving and sending links between the station and the line system, helps to deal with the normalization of large passenger flow, solves the problems of massive data calculation and storage, and meets the management needs of the overall operation data.
