Analysis of Fault Tree of Train Tracking System
Wei Cui · Journal of Guizhou University · 2010
In working process,the train tracking system is affected by the receiver fault and transmitter fault,manual intervention etc.So there are abnormal output information and improper manual intervention timing resulting in train tracking interruption.In this paper,various factors influencing the top event of fault tree(the train tracking interrupt) were analyzed,then the fault tree of train tracking was set up.Qualitative analysis and quantitative calculation were made by using fault tree analysis.The minimal cut-sets of the fault tree was found,the probability important degree and key important degree of the components and the top event of the fault tree occurred probability were computed.On the basis of above,the main factors of effecting,the train tracking were analyzed,and the corresponding improving measures was suggested.
