信息物理融合系统(Cyber-Physical System,CPS)自给出以来就备受关注。一个CPS系统设计的好坏关键取决于其设计前期的系统模型的创建。如何对一个CPS系统进行全方位、健壮性、安全性的建模是国内外研究的焦点和难点。在前人的基础之上,把CPS系统分为物理实体、计算实体和控制实体,给出了一种CPS系统计算实体的建模方法:基于动态行为建模的UML建模方法 DBM UML(Dynamic behavior modeling-UML),对整个系统的结构进行详细的分析,将其对应的状态机抽象出来,先通过状态机的动态行为建模对系统进行模型化,再通过UML建模语言对整个系统计算实体进行详细化建模,把系统的逻辑关系和反馈机制等详尽的表现出来,完成系统的计算实体建模。
Since its inception, Cyber-Physical System (CPS) has drawn much attention. The key to the design of a CPS system depends on the creation of a system model that is pre-designed. How to model a CPS system in all directions, robustness and safety is the focus and difficulty of the research at home and abroad. On the basis of the predecessors, the CPS system is divided into physical entities, computing entities and control entities, and a modeling method of CPS computing entity is given: UML modeling method based on dynamic behavior modeling DBM UML (Dynamic behavior modeling-UML), the structure of the whole system is analyzed in detail, and its corresponding state machine is abstracted. First, the system is modeled by the dynamic behavior modeling of the state machine, and then the whole system is calculated by the UML modeling language Entity detailed modeling, the system’s logical and feedback mechanisms such as a detailed manifestation of the completion of the system’s computational modeling.
