Fault Behavior in Fire Control System Based on Extendable Petri Net

Use the Petri net theory and studied out a synthetical expression method of static state and trends behavior in fire control system fault diagnose. The method may be convenient and succinct for fault phenomenon of multilayer rank order and many route. Amount of work is simplified in the fault diagnose system. The fault information characteristic, fault information molde and propagation behavior fashion are expounded. The algorithm for system fault information characteristic is put. The Petri net molde of fault diagnose administrative levels and mixed fault is set up. The fault information propagation route is gained in system analysis. The trends transition of fault behavior is analyzed, to find the solution of system the smallest cut set and path.
