面向对象建模语言UML(Unified Modeling Language)已广泛用于嵌入式系统建模,但它在嵌入式实时系统建模时存在模型重用性不高、概念模型形式化复杂和状态图对时间约束方面的建模功能不强的问题,针对这些问题,提出了对象分析模式与实时规范模式相结合的新思想,并给出了使用对象分析模式和实时描述模式进行嵌入式系统建模及模型分析、验证的方法,然后介绍了基于UML的模式驱动的嵌入式系统建模及分析的实现步骤,最后以一个实际应用进行了详细说明。
Object oriented modeling language UML (Unified Modeling Language) is applied abroad for embedded system modeling. But UML exists problems that model does not reuse and concept model is formalization complicated and Statechart does not Model well to time constraint. Concerning these problems, a new idea was proposed that object analysis patterns combined with real-time specification patterns, and a method that used object analysis patterns and real-time specification patterns to model for embedded system to analyze and validate for the model was proposed. UML-based embedded system modeling of pattern-driven and analysis approaches were introduced. An application example using the above approach was illustrated.
