第21题：
问答题CPS（cyber physical system）的概念是什么？正确答案： 集计算、通信和控制能力于一体的信息物理融合系统（Cyber-physical Systems，CPS），实现开放、动态、可控、闭环的计算和服务支持。
CPS是一类将数字化、网络化系统与物理过程密切整合的设备系统。
CPS的概念最早是由美国国家基金委员会在2006年提出，被认为有望成为继计算机、互联网之后世界信息技术的第三次浪潮核心：3Cs（Computation、Communication、Control）的融合。
“CPS，从广义上理解，就是一个在环境感知的基础上，深度融合了计算、通信和控制能力的可控可信可扩展的网络化物理设备系统，它通过计算进程和物理进程相互影响的反馈循环实现深度融合和实时交互来增加或扩展新的功能，以安全、可靠、高效和实时的方式监测或者控制一个物理实体。CPS的最终目标是实现信息世界和物理世界的完全融合，构建一个可控、可信、可扩展并且安全高效的CPS网络，并最终从根本上改变人类构建工程物理系统的方式。”解析： 暂无解析 -
