Abstract: During fault diagnosing of general fire control system, visual observation method, backup device replacement method, and fault tree analysis method are mainly used. Visual observation method requires maintenance staffs who own much experience and stronger ability. Backup device replacement method could be only used to limited situation. While adopting the method of fault tree analysis on fault diagnosis of fire control system leads to heavy workload and low efficiency caused by choosing diagnosis path incorrectly when it came to logic gates. In view of such problems, the Analytic Hierarchy Process (AHP) based on fault tree analysis is introduced, and by adopting optimized research strategy for quantizing useful information, the reasonable troubleshooting methods are obtained. The theory analysis and experimental results show that troubleshooting method optimized by AHP not only has shorter time and higher efficiency than that for blind troubleshooting method, but also has certain practical value for improving the diagnosis efficiency of the complex fire control system.
