Radio audio test device

Abstract

The invention belongs to the field of aircraft equipment test, and particularly relates to a radio audio test device. Fault analysis requires to be performed on all the related components after the fault occurs in the radio audio electrification process performed by an assembly shop, the operation mode is complex and long in time consumption and the assembly progress is severely influenced. The radio audio test device comprises an audio processing unit and a DC voltage stabilized power supply, an audio voltmeter, an audio control panel and a load earphone which are connected with the audio processing unit. The radio audio test device is applied to the electrification inspection work before system assembly so that detection of the components can be rapidly and accurately completed, the detailed detection data can be provided for fault judgment, the professionals can be assisted to perform rapid and accurate error judgment to eliminate the field fault, and the labor productivity can be enhanced, the assembling period can be shortened and the production progress can be guaranteed.

Description

technical field [0001] The invention belongs to the field of aircraft equipment testing, in particular to a radio audio testing device. Background technique [0002] The radio station is the most important and widely used aircraft radio communication equipment, mainly used for two-way language communication between the aircraft and the ground traffic control personnel during take-off and landing and when the aircraft passes through the controlled airspace. [0003] In the process of energizing the audio frequency of the radio station in the final assembly workshop, there is information exchange between the systems. After a fault occurs, it is necessary to perform a fault analysis on all related parts. The operation method is complicated and takes a long time, which seriously affects the progress of the final assembly. It must be powered on during the analysis, and it is impossible to individually detect the audio indicators of a certain radio station. At present, the labora...

[0003] In the process of energizing the audio frequency of the radio station in the final assembly workshop, there is information exchange between the systems. After a fault occurs, it is necessary to perform a fault analysis on all related parts. The operation method is complicated and takes a long time, which seriously affects the progress of the final assembly. It must be powered on during the analysis, and it is impossible to individually detect the audio indicators of a certain radio station

At present, the laboratory lacks the test device of this type of radio station to conduct pre-installation tests on the audio indicators of the radio station. In order to meet the needs of scientific research and production, it is urgent to develop
