Abstract

The invention provides a power line audio conduction sensitivity monitoring method comprising the following steps: adding a signal source output signal, and detecting whether interference intensity satisfies a first preset threshold value or not, wherein the detection interference intensity comprises a current value and / or a voltage value in a detection line; if the interference intensity meets apreset threshold value, carrying out scanning according to a preset rule, wherein the preset rule comprises residence time and a scanning rate; and monitoring the working state of the tested equipment. According to the invention, existing hardware and software resources can be fully coordinated and utilized, synchronous monitoring of test voltage and current of the audio conduction sensitivity ofthe aviation airborne power line is achieved, and automation and accuracy are achieved.

Description

technical field [0001] The invention relates to the field of aviation electrical technology, in particular to a method, system and device for monitoring audio frequency conduction sensitivity of power lines. Background technique [0002] With the continuous increase of civilian airborne electronic equipment, when a large number of electronic equipment work at the same time, a particularly complex electromagnetic environment will be formed in the aircraft cabin. In this environment, each electronic device is required to have a strong anti-interference ability to ensure that it can achieve the functions and performance that meet the specifications during normal use. [0003] RTCA DO-160G "Environmental Conditions and Test Methods for Airborne Equipment" is the current domestic and foreign general civil aircraft airborne equipment test standard, and has legal effect in the airworthiness certification of various countries. The test object of this standard is mainly for civil av...
