物理网络系统(Cyber Physical Systems,CPSs)是一种计算进程和物理进程紧密结合的智能系统.目前对于CPSs的研究还处于初级阶段,从概念模型到关键技术都没有确切描述,给相关研究者正确理解及研究CPSs造成困难.基于CPSs未来广泛的应用范围和良好的发展前景,本文对CPSs进行了系统的介绍.本文首先给出了CPSs定义,分析了CPSs与物联网的异同点,对CPSs研究现状进行了总结,以此为基础提出了一个CPSs初步的结构框架;其次着重对CPSs研究涉及到的关键技术与基础理论进行了系统讨论,最后对CPSs的研究前景进行了展望.
Cyber Physical Systems(CPSs)is an intelligent system with computation and physical processes tightly integrated.The stage for CPSs research is primary at present and it's difficult for researchers understand and research CPSs because there is not explicit description between conception and key technology.This paper gives CPSs a systemic introduction based on widespread field of application and well perspective.At first,the paper gives a specific definition and analyses the difference and relationships between CPSs and Internet of Things.The summarization of study situation in the world is presented.The architecture of CPSs is proposed in the following.Then,the paper discusses the key technologies and basic theory for CPSs systematically.In the end,the perspective of CPSs is prospected.
