介绍一卡通系统在智慧城市中的重要作用,分析近些年国内外关于一卡通系统的研究情况及局限性.为了更好地服务于智慧城市,借鉴已有的智慧城市系统构架,设计了城市一卡通系统的总体软件构架,由系统分级、系统结构和系统接口等组成,阐述了其主要功能与实现方式.采用"组件化、参数化"的思想,设计了应用系统,将公用功能组件分类、定义了实现功能.根据提出的城市一卡通系统的软件构架,设计了应用系统模型与一卡通中心系统,包含模块与子系统功能,子系统之间的互联关系以及应用示例.该设计思路在国内多个项目中已运用,对城市一卡通的建设具有一定借鉴意义.%This paper introduces the important role of the card system in the intelligent city, and analyzes the research situation and limitation of the card system both at home and abroad in recent years.In order to better serve the intelligent city, the overall software architecture of the city card system is designed by referring to the existing intelligent city system architecture, which is composed of system classification, system structure and system interface, and the main function and realization way are expounded.By using the idea of "componentization and parameterization", the application system is designed, the utility functional components are classified and the realization function is defined.According to the software architecture of the proposed city card system, the application system model and the city card center system are designed, including the model and subsystem functions, the interconnection between subsystems, and application examples.The design idea in this paper has been used in many domestic projects, which has certain reference significance for the construction of city card.
