Abstract： Aimingat the problemthatthefaultdiagnosis ofintegratedavionics informationsystem depends on theexperience ofmaintenancepersonnel，withinsufcientdegreeofintelligenceandlowaccuracyoffaultisolation，thepaperdesignsan avionics fault reasoning algorithm based on fusion BERT model. First， the BERT + CRF algorithm is used to extract and disambiguatetheentityof thefeldfaultdescriptiontext，andlocatethefaulttothemoduleobject.Then，theBERTsemantic similaritymodel is usedtoaccurately matchthefaulttothe standard failuremode，andthe troubleshooting scheme inthe historicalfaultdatabaseismatchedtoguidethemaitenancepersonneltotroubleshoot.Finallybyconstructingrealdata set，itisverifedtatteccuracycallandFsoreofteeasoningalgorithaegreatlyimproved，omparedwiththe three intelligent algorithms ofBiLSTM，LSTMand cosine similarity.
