【摘要】 主要研究了将网格技术应用于实现智能公交系统的基本思想和部分技术的实现方法.网格技术通过对异构资源的整合,能够实现更高程度的资源共享和更强的计算能力,它为实现智能公交系统提供了一种有效的解决方案.首先提出了基于"服务"的系统分层体系结构,包括资源服务层、基础服务层与系统服务层,然后阐述了基于OGSA的关于智能公交系统的信息集成、功能封装和应用开发的设计思想和方法,并且采用请求/应答与订阅/通知两种方式实现了信息集成.更多还原

【Abstract】 In this paper,grid technique is investigated and is applied in intelligent public traffic system.The stronger computing and more resource sharing is realized by integrating heterogeneous resources by means of grid.The grid is an effective method to resolve public traffic system problems.First,the layered system structure based on service is putted forward,including: resource services layer,basic services layer and system services layer.Next,the design approach of the information integration,function encapsulation and application exploitation of the intelligent public traffic system based on OGSA is studied,the information integration is realized by means of two different modes: request / response mode and subscribe / notify mode.更多还原
