一种分布式实时系统软件体系结构

Open Software Architecture for Distributed Real-time System

针对分布式实时系统的软件体系结构进行了深入研究 ,试图为应用开发者提供一个开发分布式实时系统的通用框架 .首先提出由事件总线和数据访问总线组成具有开放结构的分布式实时系统的参考模型 ;然后详细讨论了事件总线和数据访问总线的组成成分、工作原理和工作过程 ;最后 ,研究了支持平台的单一映象编程模型、实时 Qo S的支持、提供主动服务机制、灵活开放的系统结构等技术特点 .

In order to simplify the design and implementation of distributed real time system,the authors are doing some research on middleware for distributed real time system to provide programmers with a general developing framework.Firstly,this paper proposes an open system reference model consisting of event bus and data access bus;Then,discusses the components, and principal of two buses.Finally,concludes the technical features such as easy single image programming model,real time QoS services,active service mechanism,flexible configuration.
