Abstract: Objective To propose a monitor failure diagnosis method based on fault tree theory to decrease maintenance cost and increase efficiency.MethodsBased on fault tree theory and maintenance practices,a typical fault tree analytical model was established on likely faults and possible causes.The model developed was applied to the quantitative analyses of kinds of probability events to determine the causes for the faults.Results The study on some kind of faults proved the accuracy,accessibility and practicability,which facilitated the maintainer to eliminate the fault.Conclusion The method determins the cause and probability of the fault directly,and contributes to rapid and convenient maintenance of the monitor.
