Problems solved by technology

[0003] The introduction of a large number of new models has led to the complexity of the airline's model configuration
The complexity of the configuration leads to an increase in management costs, and it is difficult to form a technical echelon for maintenance
Many "difficult" faults often appear, and the use of conventional technical means (such as stringing / replacing parts according to the fault phenomenon) is often ineffective, one of which is because these faults will not directly appear or be observed (they are only abnormalities in equipment parameters) and second because the consequences of failure of these systems are often catastrophic

Abstract

The invention relates to a method for monitoring the performance trends of parts and accessories of an airplane, and the method comprises the following steps: obtaining a plurality of groups of performance data of at least one performance index of the parts and accessories of the airplane from an airborne quick access recorder at a plurality of flight phases; determining a performance trend model function according to the type of the performance index; carrying out the operation processing of the plurality of groups of performance data based on the performance trend model function, so as to obtain the performance trench analysis data; and outputting a performance trend analysis result based on the performance trench analysis data. In addition, the invention also relates to a device for monitoring the performance trend of the parts and accessories of the airplane. According to the invention, the method and device can timely obtain the possible fault conditions of the parts and accessories of the airplane, thereby enhancing planned maintenance, reducing non-planned maintenance and achieving the support for the conventional maintenance analysis technology, so as to improve the airplane maintenance work efficiency of an airline, and reduce the airplane maintenance and operation cost.

Description

technical field [0001] The present invention relates to the field of aircraft monitoring, in particular, the present invention relates to a method and device for monitoring performance trends of aircraft parts and accessories. Background technique [0002] Airborne 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 It has the advantages of easy access, simple maintenance, large data storage capacity, and cheap and common onboard storage devices. [0003] The introduction of a large number of new models has led to the complexity of the airline's model configuration. The complexity o...
