地铁AFC系统的设计及通信子系统的实现 摘要 （AFC）是城市轨道交通对AFC系统的要求非常迫切AFC系AFC系统是一个非常复先由标准和协议来保证，对于软件开发商来说，开发出能够复用的AFC系统是非常的必须的，而且是必要的，因为这样才能够节约成本和资源。 本文以在浙大网新众合轨道交通有限公司研发AFC系统的实际经验为基础，首先回顾了AFC系统相关技术和发展，研究了当前AFC系统的技术手段，重点以领域模型的理念从数据管理，系统运作管理，参数管理三个方面分析和抽取了AFC系统的核心业务以便可复用AFC系统的设计和实现，最后实现和测试了AFC的通信子系统。 关键词：　自动售检票系统，领域，可复用框架Abstract At present, Chinas cities the prevalence of the phenomenon of road congestion, urban development has become a bottleneck problem.Urban rail transport to ease urban poor to become one of the means of transport problems.To solve some traffic problems, Chinas major cities are being vigorously carried out the construction of underground rail.Automated Fare Collection System (AFC) is a modern, information technology an integral part of the subway system is one.Urban rail transit AFC system requirements are very urgent.However, the first AFC system-related technologies for decades monopolized by foreign companies in recent years, Chinas development was a lot of development work, with many results. AFC system is a very complex system, including a number of modules and subsystems, hardware and vendors involved are quite diverse.Different lines and each city generally operate by different operators, the needs are different.The production of hardware from different vendors to be compatible, different companies developed software must be compatible.First, the compatibility standards and protocols to ensure, for software developers to develop a system to reuse the AFC is very necessary, but necessary, because it can save costs and resources. In this paper, the Insigma Zhonghe Co., Ltd. developed rail transit AFC system based on practical experience, first reviewed the AFC system, the development of related technologies and to study the current AFC system of technical means, focusing on the concept of domain model from data management,system operation management, parameter management, analysis and extraction of three aspects of the core business of the AFC s
