摘　　要：为满足分布式实时应用的需求,项目管理组(OMG:Object Management Group)提出并发布了实时系统用数据分配业务(DDS:Data Distribution Service for Real-time Systems)规范。基于该规范,本文研究了发布/订阅系统的理论模型,设计了一个灵活、可靠的实时中间件(RTDDS:Real-time Data middleware),从而降低了各节点之间的时空耦合性,解决了分布式环境下数据传输的QoS和实时性问题。最后,本文给出了基于RTDDS的一个应用实例。To meet the needs of distributed real-time applications, a new specification named ＂Data Distribution Service for Real-time Systems＂ （ DDS ） is proposed and issued by OMG （ Object Management Group ）. Based on the specification, this paper carries out researches on the academic model of publish/subscribe system, and designs a flexible, reliable real-time middleware （RTDDS） , decoupling each node, and providing a solution to the data transmission problem of QoS and real-time ability. Finally, the paper present a Stock Quote Example based on the RTDDS.
