Radio compass self-checking test device

Abstract

The invention relates to an aircraft avionic system, and provides a radio compass self-checking test device which comprises an ultra-high frequency signal generator 3, a radio compass self-checking function test module 9, a radio magnetic indicator 10 and an angle position indicator 11, wherein the ultra-high frequency signal generator 3 is connected with an ADF signal simulator 2 through a radio frequency cable, and sends a radio frequency signal to the ADF signal simulator 2; the radio compass self-checking function test module 9 receives the audio output increased by a radio compass 1 according to a self-checking instruction, and sends the audio output to earphones 5; the audio output belongs to the radio frequency signal of self-checking audio frequency; the radio magnetic indicator 10 is connected with the radio compass self-checking function test module 9, and displays the azimuth analog quantity increased by the radio compass 1 according to the self-checking instruction; the azimuth analog quantity belongs to the radio frequency signal of self-checking audio frequency; the angle position indicator 11 is connected with the radio compass self-checking function test module 9, and displays the azimuth digital quantity increased by the radio compass 1 according to the self-checking instruction; the azimuth digital quantity belongs to the radio frequency signal of self-checking audio frequency.

Description

Technical field [0001] The invention relates to an aircraft avionics system, and relates to a radio compass self-checking test device. Background technique [0002] At present, our company does not have a dedicated tester for final product verification, which cannot meet the requirements of the radio compass system for pre-installation verification. It cannot test the various functions and detailed technical indicators of the radio compass system. It is directly installed and cannot be guaranteed. the quality of. When the system is energized on board to check that the system is malfunctioning, there is no effective means to determine whether the product itself is malfunctioning or the wiring or other cross-linking equipment is malfunctioning. The malfunction can only be solved on the aircraft, and the malfunction cannot be reproduced on the ground. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a radio compass self-insp...

[0002] At present, our company does not have a special tester for the calibration of finished products, which cannot meet the requirements of the radio compass system for pre-installation calibration. It cannot test the various functions and detailed technical indicators of the radio compass system. If it is installed directly, it cannot guarantee the finished product. the quality of

When the system is powered on to check that the system fails, there is no effective means to judge whether it is the fault of the finished product itself or the fault of the on-board circuit or other cross-linking equipment. The fault can only be eliminated on the plane, and the fault phenomenon cannot be reproduced on the ground.
