Abstract

The present invention relates to a method for examining an aircraft fault diagnosis model. The method comprises a step of generating first bus data which is corresponding to preset information display, a step of converting the first bus data into second bus data whose data format is different from that of the first data format, a step of inputting the second bus data into a fault diagnosis model, a step of generating simulated information display based on the output result of the fault diagnosis model, and a step of verifying the consistency of simulated information display and preset information display. In addition, the invention also relates to a device for examining an aircraft fault diagnosis model. Through the method and the device of the invention, and the key fault diagnosis logic of a real system can be verified.

Description

technical field [0001] The invention relates to the field of aircraft simulation, in particular, the invention relates to a method and a device for checking a fault diagnosis model of an aircraft health management system. Background technique [0002] On the ARJ21 aircraft, the key avionics information system consists of two parts. The first part is the integrated avionics system Proline21 provided by Rockwell-Collins of the United States. Specifically, Proline21 takes its "Integrated Processing System (IPS)" as the core, covering the flight control system (ATA27), most of the instrumentation systems (ATA31) (including flight data acquisition), navigation system (ATA34 ), the communication system (ATA23) and the central maintenance system (ATA45), which are the airborne information system platforms on the ARJ21 aircraft; the second part is the flight data recording system provided by the British L3 company, which covers the digital flight recorder in function (DFDR: Digital...
