H1总线流量的参数估计
Parameters estimation of traffic in H1 fieldbus
【摘要】 本文通过对基于H1总线的信息网络过程监控层的业务量测量,证实了该业务量具有典型的自相似性。在此基础上对基于H1总线的信息网络监控层流量与纯H1总线网络监控层流量的H值估计进行了分析与比较,得出了纯H1总线网络监控层流量的H值在一个较小的区间内波动的结论。最后在多次采样的基础上使用了均值法对纯H1总线网络监控层流量的H值进行估计。
【Abstract】 In this paper our measurements show that the real traffic has self- similarity on process monitor layer in information net-work based on H1 fieldbus. Then the paper analyzes the difference between the traffic in networks based on H1 fieldbus and the traf-fic in only H1 fieldbus networks and monitors. According to the analysis, the paper concludes the value of Hurst that is in only H1fieldbus networks and monitors fluctuates in a small range. Finally, the paper estimates the value of Hurst that is based on samplingdata many times.
