Petri Nets in the Emu Pantograph Application of Fault Tree Analysis (FTA)

Abstract:

This paper presents the fault mode and barb causality diagram of the pantograph of the emu, by settling and counting fault information of the pantograph. And fault analysis of the pantograph is used to establish the fault tree. The Petri net model of the pantograph is simplified on the base of the principle of duality and resorption by combining the modeling theory of Petri net and the fault tree. The minimum cut set is obtained by solving the above simplified model with incidence matrix. Compared to common solution of the fault tree, this integrated model efficiently simplifies computation of complicated fault tree. The method raised here saves the time of computation which increases the efficiency of analysis, and improves the accuracy of fault diagnosis.
