Automatic testing equipment and method for audio frequency management assembly of airbus aircrafts

Abstract

An automatic testing device for an audio management module of a passenger airplane and a method thereof are disclosed. The automatic testing device comprises an industrial control machine, a bus adapter, a piece of automatic testing equipment and a signal adapter. The invention makes use of the industrial control machine to run the automatic testing program sets and control the automatic testing equipment through the bus adapter so as to generate various signals needed in the test, and outputs the signals to the audio management module through the signal adapter; meanwhile, the output of the audio management module is transferred by the signal adapter and a corresponding device in the automatic testing equipment is used for data collection, then the collected data is transferred to the industrial control machine through the bus adapter and the test result is judged through data analysis and treatment function of the automatic testing program sets, thus not only avoiding the troubles of adapting to an audio control panel and requiring a special selective call signal source but also greatly reducing the test time of the automatic testing and greatly reducing man-made errors.

Description

technical field [0001] The invention relates to an aircraft maintenance device, in particular to an automatic testing device and method for an audio management component of an Airbus series aircraft. Background technique [0002] The Audio Management Unit (AMU) is an integral part of the advanced cabin entertainment and service system, which is used for the management and control of audio resources on the aircraft. According to statistics, the audio management component is a key device that is prone to failure. If it cannot be repaired quickly and accurately, it will definitely affect the normal flight of the aircraft. At present, the AMU test of the Airbus series aircraft generally adopts the auxiliary debugging method with the aid of the Audio Control Panel (ACP) and a dedicated selective call signal source, so it is still at a relatively low level, so there is no space so far. Special automatic test equipment and method for audio management components of passenger series...
