Problems solved by technology

[0003] However, ACMS on old aircraft does not have the data analysis and processing functions of advanced aircraft (such as Boeing 777, 787). Fault information informs the flight crew. After the aircraft fails in the air, the ground personnel often cannot be informed in time. As a result, the troubleshooting work can only be carried out after the aircraft lands, which is likely to cause flight accidents and flight delays. Maintenance costs
On the other hand, with the development of domestic civil aviation transportation, the fleet size of airlines is getting larger and larger, and the requirem...

Abstract

The invention provides an aircraft fault real-time monitoring method and system based on an ACMS. The method includes the steps that aircraft technical manuals and ACMS technical specifications are acquired; according to the aircraft technical manuals, aircraft fault characteristic parameters are extracted; according to the ACMS technical specifications, aircraft fault characteristic parameters are written into an ACMS parameter library, and an ACMS fault parameter library is built; according to the aircraft fault characteristic parameters and the ACMS technical specifications, an aircraft fault monitoring program is programmed; the ACMS fault parameter library is introduced into the aircraft fault monitoring program, and aircraft fault information is output. Flying conditions of an aircraft can be acquired in real time based on the ACMS, aircraft faults are monitored through the program, time is earned for removing the faults, the frequency of occurrence of flying accidents and the frequency of flight delay can be reduced, and operation efficiency and safety level of an airline company can be improved.

Description

technical field [0001] The invention relates to the technical field of aircraft maintenance, in particular to an ACMS-based aircraft failure real-time monitoring method and an ACMS-based aircraft failure real-time monitoring system. Background technique [0002] ACMS (AIRCRAFT CONDITION MONITORING SYSTEM), that is, the aircraft condition monitoring system, is equipped on old-fashioned aircraft, such as Boeing 737, which occupies more than half of the domestic civil aviation transportation market. Monitor engine status, flight performance, and conduct special engineering investigations. Usually, various raw data collected by ACMS are saved through digital flight data recorder (DFDR) and quick access recorder (QAR), and are used for flight management and Used by flight attendants. [0003] However, ACMS on old aircraft does not have the data analysis and processing functions of advanced aircraft (such as Boeing 777, 787). Fault information informs the flight crew. After the...
