轨道交通行业信息化集成方案探讨

分析轨道交通信息化现状，认为信息化起步早的运营企业逐渐开始面临信息系统分散、异构、应用孤岛的问题。不同技术平台应用系统之间的集成整合问题，在信息化规划期就必须尽早充分考虑。通过比选信息化的3种集成方案，即大而全的“航空母舰式”、整齐划一的“电报式”、基于标准接口的“拼接积木式”，认为广泛应用于电力、航空、船舶等行业、面向服务的架构体系SOA (service-oriented architecture)最为灵活。但是，SOA体系结构本身也有缺陷，轨道交通行业如果采用这种先进体系结构，需要在集成方案设计中设法弥补不足。

Research on rail transit industry information integration scheme

With the in-depth development of railway industry, the enterprises implemented information system early is now facing the challenge of systems decentralization, asynchronization and stand-alone. This is a warning for the enterprises planning to implement information system that needs to evaluate the system integration problem among different technology platforms in project preparation phase. After comparing several information integration solutions, Service-Oriented Architecture (SOA) is very outstanding and flexible solution, which is widely used in electric power, aviation, shipbuilding and other industries, however, SOA has itself defect, railway industry needs to make up for its deficiency if they want to introduce this architecture.
