摘要
故障树作为系统可靠性分析的一种工具,在实际工程中已得到广泛应用。二元决策图作为常用的故障树分析法,通过其结构优势可快速得到故障树的不交化割集,通过分析割集集合确定系统失效集合以及计算系统失效概率等指标,确定系统可靠性。在.NET平台上使用ITE算法实现故障树对二元决策图的转化,并在通用的CAN总线监测诊断平台上实现,平台使用SQL Server作为知识库存储信息数据,以故障树信息和监测数据作为输入,实时对系统报警做出诊断。
Fault tree analysis method is a useful reliability analysis tool,and it is used in applications of practical engineering widly.Binary Decision Diagram( BDD) is a common used fault tree analysis method,the disjoint cut sets of the fault tree can be quickly obtained by its structure advantage.The reliability indexes of the system such as the failure sets of the system and the fail-ure probability of the system are determined by analyzing the collection of cut sets.An algorithm achieve transformation from fault tree to binary decision diagram is proposed.This algorithm is applied in a CAN-bus monitoring and diagnosis platform using SQL Server as information database,fault tree information and real-time bus data as input.
