摘要
阐述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。在本文中,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/知两种方式实现了信息集成。
Grid can provide stronger computing and more resource sharing by integrating heterogeneous resources. It is an effective method of resolving public traffic system problems. The service - oriented layered system architecture is presented, which includes ： resource services layer, basic services layer,system services layer. Next, the 3 different abstract levels are discussed, including：information fusion,function encapsulation and plicationintegration. Meanwhile,based on OGSA,two different modes--request/response mode and subscribe/notify mode realize information fusion.
