【摘要】 针对1553B总线的实时性评估问题,提出一种基于有色Petri网(Colored Petri Net,CPN)的1553B总线模型;该模型基于分层建模的思想,分别建立了1553B总线的拓扑模型、总线控制器模型、远程终端模型和总线信道模型,有效刻画了1553B总线的拓扑结构和动态行为;仿真实验验证了所建模型的正确性和有效性,该模型可为构建满足特定实时性要求的1553B总线系统提供理论依据。更多还原

【Abstract】 Aiming at the problem of real-time performance evaluation in the 1553Bbus,a new model for the 1553Bbus with colored petri net(CPN)is proposed.On the basis of hierarchical modeling idea,topology model,bus controller model,remote terminal model,bus channel model of the 1553Bbus are built up,which can describe the topology and behavior in the 1553Bbus.A case study of the 1553Bbus is given to verify the proposed model,and it can give the theory evidence for design of the 1553Bbus meeting the real-time performance.更多还原
