摘要 以确定与随机Petri网(Deterministic and Stochastic Petri Net,DSPN)为数学工具,提出一种基于DSPN的1553B总线传输机制建模与性能分析方法。按照自顶向下的建模思路,分别建立了同步消息传输模型、异步消息传输模型和消息传输通道模型,然后综合各个模块模型构建了1553B总线传输机制的DSPN模型。最后,以总线负载和延迟时间为性能指标,通过仿真实验考察了异步消息对系统性能指标的影响,验证了所提方法的正确性和有效性。 A new modeling and performance analysis method of 1553B bus transfer mechanism is presented by using deterministic and stochastic petri net (DSPN). According to the top-down modeling idea, synchronous message transfer model, asynchronous message transfer model and message transfer channel model are established, and all module models are integrated to construct the 1553B bus transfer mechanism model. Busload and delay-time are used as performance index to analyze the influence of asynchronous message on the system performance index and validate the proposed method
