摘　　要：分析了UML在实时系统设计中的优点和需要解决的主要问题,论述了基于UML RT的实时嵌入式系统设计方法,并且对其进行扩展以支持数据流计算模型的建模,最后以汽车巡航系统为例加以说明。Along with the functions of real-time embedded systems becoming more and more complex, and the market press becoming pricking up, the design of real-time embedded systems needs modern software engineering methodologies. Rather recently, using UML in real time domains becomes a hot topic. Real-time embedded systems usually are compositions of event-driven discrete systems and dataflow-based continuous systems. But the extensions of UML for real-time domains (UML-RT) only support event-driven systems modeling. This paper first analysed the advantages and problems of using UML in real time systems design. Second, it discussed UML-RT based real-time embedded systems design methodology and proposed an extension of UML-RT to support Dataflow modeling. Finally, this paper presented an automobile cruise control system as an example to illuminate this methodology.
