摘要
飞机电气线路故障检测是飞机维护的一项重要内容,由于线路繁多布局复杂,检测起来较为困难。本文设计了一种便携式飞机线路多功能测试仪以解决这一难题,可以进行线路故障的检测、分析和定位。通过对飞机的各种线路故障进行分析、总结、分类及对各种检测方法进行比较分析,确定脉冲检测法方法为测试仪的主要检测方法。多功能测试仪主要实现线路故障性质确定、故障筛选和线路故障定位等功能。本文重点研究故障判断及其定位方法,对检测原理进行了详细地分析,设计了电路原理图,编写了相应的软件程序,并给出线路测试仪的基本构型。
Detecting the aircraft circuit fault is a main content of the aircraft maintenance, owing to the numerous circuits and complicated layouts, fault detecting becomes more difficult. A portable multifunctional testing instrument is designed in this paper, which can be used for the fault detecting, analyzing and locating of the aircraft wiring. Various types of circuit breakdown in the aircraft are analyzed, summarized and classified, the pulse method is selected as the main detection principle of the testing i...
