城市轨道交通自动售检票系统多线共用中央计算机系统建设方案分析

摘要

The development situation of the AFC system in Shanghai rail transit is introduced,the necessity of MCC system design is discussed.Then the advantages and disad-vantages in technical routes of 3 MCC plans:the discrete structure,virtual resource structure and cloud structure are analyzed,and the virtual resource structure is recommen-ded for the design of MCC in Shanghai rail transit.Finally, the disaster recovery strategy of MCC is briefly illustrated.%介绍了上海轨道交通自动售检票(AFC)系统的发展现状，论述了集中设置多线中央计算机(MCC)系统的必要性，分析了分立架构式、资源型架构式和云服务架构式三种集中设置 MCC 系统方案技术路线的优缺点。推荐采用资源型架构式方案作为上海轨道交通 MCC 系统的设计思路，并对 MCC 系统的容灾策略进行了简要说明。
