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.
