摘要
针对粮库监控系统总线网络缺乏可靠性评估手段的难题,引入广义随机Petri网建模与分析技术,建立了粮库监控系统总线网络可靠性分析模型.该模型有效地模拟了各类故障在粮库监控系统总线网络中的动态行为.在TimeNET 4.2软件环境下实现粮库监控系统总线网络可靠性分析模型,分析了系统可用度的动态变化趋势及原因,验证了模型的正确性和有效性.模型可以为粮库监控系统总线网络的可靠性评估提供参考.
In view of the problem that there are more difficulties in the reliability analysis of the bus network of granary monitoring and control system （GMCS）, the generalized stochastic petri net （GSPN） in the application of reliability analysis of bus network of GMCS is introduced. The reliability analysis model of bus network of GMCS is constructed. It can describe the dynamic behavior of all kinds of faults in bus network of GMCS. The reliability analysis model of bus network of GMCS is realized in the software TimeNET 4.2 and the dynamic change trend and the cause of availability is analyzed to validate the proposed model. It can provide theoretical basis for the reliability analysis of bus network of GMCS.
