Abstract

The invention discloses an all-intelligent aircraft flight test error analysis system. The system comprises a test data management module, a flight test data analysis module, an intelligent fault diagnosis module and a human-computer interaction module. The test data management module supports batch import and unified management of test data. The flight test data analysis module performs data processing and feature extraction on the test data. The intelligent fault diagnosis module conducts intelligent reasoning and rule matching and diagnoses system faults according to symptom characteristicsobtained by the data analysis module and a knowledge rule of a knowledge base. The human-computer interaction module can control the whole process, and dynamically display the data analysis and faultpositioning processes and results of the system in real time. The system has the advantages that the data analysis results can be quickly given, system faults are accurately positioned, the test datais imported in batches, the test data is managed in a unified mode, the diagnosis process is automatically carried out, the diagnosis results are dynamically displayed in real time, the diagnosis process is autonomous and controllable, and the openness is good.

Description

technical field [0001] The invention relates to the technical field of aircraft flight test error analysis, in particular to a fully intelligent aircraft flight test error analysis system. Background technique [0002] At this stage, the error analysis of aircraft flight test mainly relies on experts to manually analyze and interpret the flight test after each flight test. There are hidden dangers of missed judgment and misjudgment in manual interpretation; in recent years, with the development of computer technology, there are also fully automatic The data interpretation system and the fully automatic fault diagnosis system, but mainly manual data interpretation and manual fault diagnosis. [0003] The flight test error analysis system includes a database module, a criterion library module, a data analysis module, an expert knowledge base module, and an intelligent fault diagnosis reasoning module. The test data is imported into the system in real time or offline, and the ...
