Abstract:

Cyber physical system（CPS）is the network-physical-equipment-system based on the depth context awareness,fusion computing,communication and control（3C）abilities,which realizes the real world and cyber world coordination and interactive to increase or expand new functions,and provides the real-time perception,dynamic control and cyber feedback and other services with the influence and feedback loop between the calculation process and physical process.The paper introduces the background and concept of CPS,gives a detailed analysis about the opportunities and challenges of the research on CPS.Some important scientific basis and key technology are analyzed.The future research and the new development trends of CPS are surveyed in this paper.

Key words: cyber physical system, ubiquitous network, Internet of Things, embedded system
