摘　　要：以确定随机Petri网为工具,对具有优先级消息的FC-AE-1553网络进行建模仿真,根据仿真计算出在事件消息间有优先级和没有优先级两种情况下消息的传输延时,通过对两种情况下的仿真结果进行对比分析,对理解具有优先级的事件消息在FC-AE-1553网络中的传输机制以及体会优先级对紧急消息处理的重要性提供了重要的理论依据。This paper takes deterministic and stochastic Petri net as a tool to model a simulated FC-AE-1553 network with priority messages.It also calculates the transmission time-delay of the system with priority between event messages and another without priority between event messages according to simulation results.By analyzing and comparing the datas of the two cases,it provides an important theoretical basis to gain understanding of the transmitting mechanism of event messages with priority in FC-AE-1553 network and the importance of priority to emergency message processing.
