Abstract:

CyberPhysical System (CPS) is currently one of the forefronts of cross research fields. It has wide application prospect, and its research and development cannot continue without the support of data transmission and management technology. In this paper, we propose a model of CPS based on software defined resources. The allocation and scheduling of resources is implemented through the way of using mapping resource description files. On the basis of this model, we present a data transmission mode of controlling the CPS in real time. This data transmission mode is implemented by middleware. This middleware employs a kind of serialization and deserialization methods in CPS, which is able to meet the requests of crossplatform, across networks and realtime communication in CPS. Besides, the paths of data transmission in CPS are designed in order to improve the efficiency of communication. Experimental results show that the serialization mechanism of data transmission is feasible.
