ABSTRACT
In the traditional concepts of computing systems and physical systems, the cyber space separates from the physical world (Rajkumar 2010). With the development of embedded computing, sensor monitoring, wireless communication, data processing and other technologies, the physical processes, computing processes and communication processes can be highly integrated which leads to the Cyber-physical system (CPS). The CPS represents a system which tightly integrates computation, communication and physical processes (Wen 2012). In CPS, through dynamic sensing of physical environments and resources, real-time reliable information transmission, comprehensive computing processing of data, with feedback cycle, the physical process is eectively controlled. Moreover, the whole process is completed automatically with people in the auxiliary position
CPS is involved in computer science, network communication and control theory and multiple disciplines which are widely applied to real systems, including transportation, aerospace, telemedicine, power control and many large infrastructure systems (Li 2011, Li 2012 & Sha 2008), and other local or fine systems such as precision agriculture, electronic endoscope. The impact of CPS will far bypass the IT revolution at 20th, and it will change the interactive mode between human and physical world just as the Internet has changed it among humans.
