TAN Peng-liu, WANG Ya-ya, ZHU Ming. Real-time event CPS model based on hybird spatial-temporal Petri nets[J]. 2016, 35(10): 32-35. DOI: 10.13873/J.1000-9787(2016)10-0032-04.
On the basis of analyzing characteristics of cyber physical systems( CPS)
propose a new architecture of CPS
and formal definition of events is given. A new formal modeling method of CPS physical entity is proposed and defined. Introduce spatial and temporal factors and continuous variables on the basis of Petri nets
hybird spatial-temporal Petri nets( HSPN) is constructed
HSPN can not only describe behavior of physical entities in logical and time-level
but also can describe change of state caused by position change of physical entities. HSPN model is applied to real-time events CPS model design
