英文摘要: Cyber-Physical Systems (CPS) integrate mixed-criticality tasks into the same platform of computation and communication so as to efficiently utilize the physical resources. This project exerts the mixed time-triggered/event -triggered operating mode, uses co-design of computation and communication, and studies how to build a safe, efficient, compositional and scalable mixed-criticality integrated architecture based on the new hybrid communication protocol. The main contents include: the dynamic compositional and efficient integration architecture for mixed-criticality applications in CPS; the strong real-time enhancement mechanism for time-triggered tasks through co-design of computation and communication; the timing quantitative analysis for compositional scheduler of mixed-criticality tasks; the high safety and reliability enhancement for distributed CPS through fault tolerant mechanism. The proposed new mixed-criticality tasks integration mode in CPS will optimize the resources of computation and communication, coordinate the system running process, and provide the high safety and reliability assurance. The study on the compositional mixed-criticality CPS has important theoretical significance and broad application prospects.
