In order to understand the development direction and trend of Cyber-Physical System(CPS)as well as the knowledge map analysis method,a visual analysis of CPS literature is carried out in this paper.The results show that,research hotspots with high centrality include penetration and convergence of IoT and CPS systems,intelligent manufacturing based on CPS,and enhanced optimization of state estimation func-tions.Frontier research directions include power grid systems and CPS integration,information system at-tack research and defense optimization.Frontier research topics include the fusion application of digital twin and CPS,the application of CPS in intelligent manufacturing,the collaborative operation of CPS,IoT and cloud computing.Finally,this paper puts forward relevant countermeasures and suggestions for the follow-ing research in the field of CPS.
