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。In this paper our measurements show that the real traffic has self-similarity on process monitor layer in information network based on H1 fieldbus. Then the paper analyzes the difference between the traffic in networks based on H1 fieldbus and the traffic in only H1 fieldbus networks and monitors. According to the analysis, the paper concludes the value of Hurst that is in only H1 fieldbus networks and monitors fluctuates in a small range. Finally, the paper estimates the value of Hurst that is based on sampling data many times.
