| 摘 要： | 针对特种车载总线网络可靠性难以评估的问题,提出采用随机高级Petri网(Stochastic High-level Petri Net,SHLPN)分析特种车载总线网络可靠性。深入分析特种车载总线网络故障模式的基础上,将其等效为冗余总线控制器模块、远程终端模块和冗余链路模块的串联,分别建立各个模块的SHLPN模型,得到了各个模块的稳态可用度计算式,进而综合得到特种车载总线网络的稳态可用度计算式。最后,实例分析验证了所提方法的有效性。

Reliability Analysis of the Special Vehicular Bus Network with Stochastic High-level Petri Net |
| |
| Abstract: | In view of the problem that there are more difficulties in the reliability analysis of the Special Vehicular Bus Network (SVBN),this paper presents to introduce Stochastic High-Level Petri Net (SHLPN)in the application of reliability analysis of SVBN. On the basis of analyzing the fault mode of SVBN,it is equivalent to the series system composed of bus controller,remote terminal and link modules. The model of every module is built up and the steady state availability formula of every module is obtained,and the steady state availability formula of SVBN is obtained. A case study of SVBN is given to verify the proposed approach. |
