轨道交通企业应用集成方案设计与实践

摘要

Integrated technological applications are needed for the complicated business of rail transit companies.Planning and designing of the application is of great importance to avoid "information silos".This paper cited the experience of IT application in Hangzhou Metro as an example to illustrate the layout and scheme of the integrated applications,which are classified into different layers in a bid to provide a unified and extensible technical architecture.An integrated system with service-oriented architecture (SOA) is presented,which includes the features of data,services,processes,information display and secure access.The technical standards that this integrated system should comply with are also proposed and proved by practical cases.It is shown that the system is prospective and of use for rail transit companies.The influences of cloud computing and big data on the system are also elaborated.%轨道交通企业的业务比较复杂,需要各类应用系统提供技术支撑.为避免产生“信息孤岛”,必须预先做好信息化规划和应用系统集成方案.根据杭州地铁信息化的经验,对轨道交通企业的应用系统进行层次划分,设计出可扩展的企业应用技术架构,以及面向服务的系统集成方案,主要包括数据、服务、流程、信息展现和安全访问集成等内容.同时,提出系统集成的技术规范,用实际案例进行说明.实践表明,本方案有一定的完整性和前瞻性,对轨道交通企业的应用集成有一定的参考意义.另外还分析了云计算、大数据等技术对应用集成方案的影响.
