FlexRay总线动态段传输延迟概率模型

Probabilistic Delay Model of FlexRay Dynamic Segment

考虑了在不同长度,不同出现概率的消息共享FlexRay总线动态段数据帧的情况下,对FlexRay总线动态段延时进行分析。在马尔科夫链模型的基础上,对提出的具体问题进行了分析。以传输延时概率度量FlexRay总线动态段消息帧传输延时。在此模型基础上进行了推广,将其应用于一个多周期的传输过程中,通过MATLAB仿真,其结果表明此模型能真实的反应FlexRay总线动态段数据帧的传输延迟过程。

Considered the conditions that vary length and vary probability message share one FlexRay dynamic data frame.In this condition analyze the delay of FlexRay dynamic segment data frame.Base on the Markov Chain,Construct our model that uses the delay probability to measure the FlexRay dynamic delay.Spread model from one cycle to multi-cycle,and then use MATLAB simulates the model.The result shows that the model can react the process of FlexRay dynamic segment data.
