摘　　要：信息物理融合系统是将物理世界与信息系统混合的混合系统,包括了设备感知、网络通信、计算与控制设备等多种组件,其系统操作既包括离散又包含连续的过程。针对上述CPS诸多复杂的特性,将以一种以数据驱动事件的扩展Petri网模型对CPS进行建模。首先,对事件的描述引入时间和空间属性;其次,引入条件变迁描述库所令牌的变化情况;最后对装有前撞预警系统的车辆进行Petri网的建模分析。The Cyber-Physical System is a hybrid system that mixes the physical world with the information system,including various components such as device perception,network communication,computing and control device,and its system operations in⁃clude both discrete and continuous processes.Aiming at above characteristic,an Extended Petri Net model based on data-driven events is proposed.Firstly,time and space attributes are introduced into the description of events.Secondly,conditional transition is introduced to describe the change of token in the place.Finally,the vehicle with forward collision warning system is modeled and analyzed.
