摘　　要：分析了开发实时系统和实时软件系统的特殊性 ,讨论了传统实时软件系统开发技术 (包括 RTSA技术、DARTS技术、JSD技术、NRL方法、OOA & OOD技术等 ) ,并比较了它们各自的优缺点 .详细讨论了面向对象技术在实时软件系统开发中的应用 ,对统一建模语言 (U ML)在实时软件系统中的应用也进行了深入分析和讨论 .在分析了实时 UML (U ML - RT)的不足之后 ,提出了融合 U ML和 CPN的实时软件开发技术 ,并用一个实例说明了如何利用该技术进行实时软件开发 .Problems faced in the development of real-time system and real-time software are analyzed. Four traditional development methods (including RTSA, DARTS, JSD, and NRL) used in real-time software system are discussed and compared. Then, the new method, Object-Oriented Analysis and Design (OOA&OOD) used in real-time system, is put forward and probed into. The UML and UML-RT technology used in the OOA & OOD are also discussed. In order to verify and validate the model of real-time software system, the novel method, which unites CPN in the UML, is summarized. Finally, a real-time case using UML and CPN is studied. The result shows that using the UML (include UML-RT) and CPN to develop real-time software system is very effective and the verification and validation of model can be carried on at the early stage.
