Embodiment 1

[0059] The optional audio management component REU5140 of the Boeing 737 series aircraft is selected as the test object, and the VHF1 and HF1 of the captain's position are used as the test channel to complete the frequency response distortion and other test items.

[0060] To start the setting interface, the user can select the corresponding test piece number, test item and related test parameters on the interface. After completing the settings, click "OK" to start the test and enter the automatic test stage. You can pause, continue or stop the test at any time during the test. After the test is completed, if no fault is detected, the test result shows normal.

Embodiment 2

[0062] Detect the optional audio management components AMU2790 series and audio control panel ACP (part number: 1167015) of Airbus 319 / 320 / 321 series aircraft. Complete the parameter setting by starting the setting interface, and click "OK" to enter the automatic test stage. A fault was detected in the input\output circuit board in ACP1167015.

[0063] Establish the output state fault injection interface, which reflects the situation of the entire communication system when the ACP outputs the signal to the AMU. The injected fault consists of 6 frames of data words, 8 bytes per frame, and a total of 48 digital signals. In this example, the excitation signal is generated in the SPARE INPUT, ILS-C, HF-R and other channels, and the PAM analog signal input is set to 3.5, the control signal word is 0011, and the corresponding s-a-0 or s-a is injected into the chip fault injection column on the right -1 and other failures.

[0064] After the diagnosis result is obtained, click the...

Abstract

The invention relates to a device and method for automatic test and fault diagnosis of a plane audio integrated system, which are used for maintaining the plane audio integrated system of Airbus series and Boeing series. The method comprises the steps of: operating test software by an industrial personal computer to provide a man-machine interaction environment, and carrying out analysis, computation and statistic treatment on acquired data so as to further complete fault diagnosis; compiling a fault diagnosis program according to all circuit diagrams and test point information of the audio integrated system, provided by a CMM (Capability Maturity Model for Software) manual, and clearing up injected data information on faults, excitation, response and the like to form a fault record in a fault dictionary; in the fault diagnosis program, providing the positions of testing points in need of manual measurement and corresponding test information; testing the testing points in need of manual measurement by detection personnel to confirm a fault area, and displaying corresponding diagnosis results. The device and method provided by the invention can commonly meet the requirement of the automatic test for two types of audio integrated systems including the AMU (Audio Management Unit) of Airbus series planes and the REU (Remote Electronic unit) of the Boeing series planes, and are favorable for reducing the labor intensity of maintenance personnel and improving maintenance efficiency.

Description

technical field [0001] The invention relates to the technical field of civil aviation maintenance, in particular to an automatic test and fault diagnosis device and method for an aircraft audio integrated system of an Airbus / Boeing model. Background technique [0002] In the communication management system of Airbus series and Boeing series aircraft, the audio management unit (Audio Management Unit, AMU) of Airbus series, Boeing 747 and new series aircraft and the aircraft remote control electronic components (Remote Electronic Unit) of Boeing 737 and other older models Unit, REU) is a very important component of the audio integrated system, and the above-mentioned components are used for management and control of audio resources. Statistically, these audio complexes are prone to failure. Moreover, they are the central equipment for the cross-linking of the flight management computer and multiple sets of signals. If the integrated audio system fails to be repaired quickly a...
