In order to take full advantages of the mass aviation data from the air force equipment,and find useful information which could serve the RCM(reliability centered maintenance) better,the modern data analysis technologies is introduced to current diagnostics,and an INS(inertial navigation system) condition data analysis and diagnostic system of one kind of plane is designed.This paper describes the data analysis procedure of the system,studies on the auto-reading and judgment,data filter and modification of it.Then an SVM model is presented,which contains the regression and the classification model.Based on these models,two methods are putted forward;one diagnoses the equipments by comparing the forecast value from the regression model with real value,the other by classifying the faults through condition data and corresponding fault information database.Finally a group of real data are used to verify and evaluate these methods.
