Problems solved by technology

However, the main storage form of the existing QAR data after decoding is CSV (Comma Separated Variables) files. Using CSV files in aircraft maintenance analysis engineering applications has problems such as inflexible storage calls and limited data operations. Engineers use CSV files for The data processing workload of maintenance analysis is heavy and inconvenient to use, which seriously affects and restricts the application and promotion of QAR data in the field of aircraft maintenance

Abstract

The invention provides an aircraft maintenance quality analysis oriented QAR (quick access recorder) data preprocessing method and device. The method includes the steps: acquiring a data file of a CSV (comma separated variables) format; acquiring flight information from the data file, and optimizing the parameter items into new parameter items; acquiring parameter values corresponding to the parameter items from the data file, and processing the parameter values; generating a structured QAR database based on the flight information, the new parameter items and the processed parameter values. A universal CSV file processing program is realized, a QAR data preprocessing tool is provided, time for data processing by engineers is reduced, skill requirements on data processing analysts are lowered, efficiency of QAR data processing and analytical application is increased, and further operating efficiency and economic benefit of airlines are increased.

Description

technical field [0001] The present disclosure generally relates to the field of flight data processing. In particular, it relates to a QAR data preprocessing method and device thereof for aircraft maintenance quality analysis. Background technique [0002] Quick Access Recorder (QAR) is an important "member" in the flight data recording system (ATA31) of modern civil aviation airliner. Compared with the traditional "flight accident recorder" (FDR or DFDR), QAR not only faithfully records a large number of operating parameters from various systems of the aircraft, and continuously and completely reflects the actual state of the aircraft system in operation or the symptom signal of failure, but also , QAR has the advantages of easy access, simple maintenance, large data storage capacity, and cheap / common use of onboard storage devices. At present, QAR data is widely used in airline engineering and has become an effective technical means to ensure flight safety. However, the...
