轨道交通自动售检票系统的RAMS设计

RAMS Design of the AFC System in Rail Transit

系统地阐述和分析轨道交通自动售检票AFC系统RAMS的基本要求,以及在设计阶段的主要任务。结合运营经验,针对AFC系统不同层面提出RAMS的设计指标。根据AFC系统对财务安全及系统安全的特殊需求,提出其安全体系应将技术与管理并重,按照安全系统工程的理念加以构建。

This paper describes the fundamental demands for RAM S （Reliability, Availability, Maintainability, Security） of Automatic Fare Collection System in rail transit and its main tasks at the design stage. Incorporating the operating experience, RAM S specifications are provided to the different levels of the AFC system. In light of the special demand of financial and system security, the security system is suggested to be built on the basis of both technology and management and the concept of security system engineering.
