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.
