轨道交通清结算系统的分析与设计

Analysis and Design of the AFC Clearing Center for Rail Transit

清结算中心(ACC)是轨道交通自动售检票系统(AFC)的核心部分和轨道交通网络化运营的基础。本文在讨论ACC系统职能基础上,详细分析了ACC系统的逻辑架构,将其分为核心业务、业务支持和公共服务三大部分,设计了ACC系统网络架构和软件架构。软件架构采用三阶层B/S和C/S混合结构方式。

Automatic fare collection clearing center （ACC） is the core of the automatic fare colle busin provi busin softw mode ction （AFC） system for rail transit, which is the base of the transportation network ess. Having discussed the ACC system functions, the ACC system logical structures were ded in detail. The ACC system logical structure includes three parts, that is, core ess, operational support and public service. The ACC system network architecture and are architecture is designed. So, its software architecture adopts three class mixed structures including B/S and C/S.
