Spatiotemporal Modeling Method of Cyber-physical System Based on Object-oriented

The Cyber-Physical System (CPS), which combines computing units and physical entities, is an extremely complex distributed real-time cyber-physical system. Aiming at the problems and challenges faced by its system modeling, this paper will focus on analyzing the time-space characteristic model of CPS, and propose to analyze and study CPS from the perspective of time and space. The physical entities in the model are abstracted into objects, then the objects in the model and their running processes are analyzed from the two dimensions of the attributes and operations of the objects. Combine CPS, Petri nets, spatiotemporal characteristics and object-oriented to form a new modeling idea-object-oriented spatiotemporal Petri nets (OOSPN). V2V technology vehicle dynamic analysis and optimization cases will be used to verify the effectiveness of the object-oriented spatiotemporal Petri net model. And draw the object model diagram of the Petri net of the case, which provides new ideas for the development of time-space characteristics analysis.
