Aiming to solve the problem of no well reflecting the spatial-temporal characteristic of CPS in current CPS event model, a new spatial-temporal event model based on multi-tuple for CPS is proposed in this paper.The basic idea of the new method is that we use the five tuples (object, time, space, event and property) to express a CPS event. As a result, our supposed model not only can more comprehensively reflect the spatial-temporal characteristic of CPS event, but also can reflect the dynamic change feature of external environment.The simulation results show that our proposed model scheme has a good performance in terms of reducing event average localization error rate and lowering event average timing error rate compared with other general event model methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
