Flight data knowledge acquisition system and acquisition method thereof

Abstract

The invention provides a flight data knowledge acquisition system and an acquisition method thereof. The flight data knowledge acquisition system mainly comprises a flight data acquisition module, a flight database module, a mode selection module, a data preparation module, a data display module, a task execution module, a rule output module, a rule processing module, a knowledge acquisition module and a knowledge base module; and the system inputs and processes flight data, extracts useful data forming rules through rule acquisition operation, and supplies the useful data forming rules serving as knowledge to a user. The flight data knowledge acquisition method mainly comprises the following steps of: processing the input flight data, digging association rules by adopting an Apriori algorithm or a Mulit-Rule method, and supplying the extracted rules serving as knowledge to the user. The system and the method reduce the maintenance difficulty of a knowledge base by eliminating redundancy rules and merging the rules, implement an automatic knowledge acquisition process by using an association rule method, are suitable for processing multi-dimensional and single-dimensional data, and reduce manual input and dependency on expert experiences.

Description

technical field [0001] The invention belongs to the field of flight parameter data processing, and in particular relates to a flight data knowledge acquisition system and an acquisition method thereof. Background technique [0002] Flight data is a series of flight parameters related to aircraft performance and state recorded by flight data recording equipment during the process of aircraft takeoff and landing, and plays an important role in flight action recognition, equipment performance trend analysis, and flight accident identification. [0003] At present, it is an important research direction to use flight data for fault diagnosis and trend prediction, and to realize aircraft condition-based maintenance. Base. Therefore, the acquisition of knowledge in the knowledge base becomes the bottleneck of the flight data expert system. [0004] According to the degree of automation of knowledge acquisition, knowledge acquisition can be divided into semi-automatic knowledge ac...

AI Technical Summary

Problems solved by technology

At present, the research on knowledge acquisition method of flight parameter data by using association rules has been initially carried out at home and abroad, but all of them are processed for single-dimensional data, and no corresponding system has been formed.
