Application of Fault Model of Gun Control System Based on Petri Net

By analyzing the structural composition and fault characteristics of a certain type of tank gun control system, the method of establishing the fault tree model is introduced. In order to solve the problem of the low-level repetitive events and incapable of dynamic diagnosis of fault tree in complex systems, the Petri net modeling method was applied to the fault diagnosis model. On the one hand, the diagnosis is performed using the incident matrix and the state equations, which improves the speed and efficiency of fault diagnosis. On the other hand, through the assignment and transfer of token, we can dynamically show the specific propagation process of the fault of gun control system. Combining with a certain type of test system in the project group, the application of petri net in fault diagnosis of gun control subsystem was realized.
