| description | The traditional fault isolation program uses the conventional static fault tree for fault analysis,which may lead to incomplete fault cause analysis,too cumbersome fault isolation path and other problems. A method of fault isolation program analysis based on system principle and dynamic fault tree is proposed. Taking the fault of the bleed air overheat detection system of an aircraft fire protection system as an example,the system design schematics and fault alarm logic analysis are carried out in depth,and a dynamic fault tree with sequence correlation,function correlation and backup relationship is constructed by using dynamic logic gates,and then correlation fault analysis and troubleshooting flow chart transformation are carried out. The results show that the method can systematically and comprehensively reflect the fault trigger logic,provide a fast and effective fault isolation path,and has good application prospect and popularization value in the line maintenance field of complex aircraft systems. |
