Application of Fault Dictionary Technology in Fault Diagnosis of Airborne Power Supply System
机载电源系统 发电机控制器 故障诊断字典 故障树分析 airborne power supply system Generator Control Unit (GCU) fault diagnosis dictionary Fault Tree Analysis (FTA)
摘要
以机载电源系统为背景,针对发电机控制器(GCU)的功能特点和组成,建立了GCU的故障诊断字典。利用故障树分析结果和故障诊断字典规范了GCU故障判定的工作模型,以确定其故障检测点,降低诊断的复杂性,提高故障诊断效率。
Abstract
Taking the airborne power supply system as the background, and considering the function characteristics and composition of Generator Control Unit (GCU), we established the fault diagnosis dictionary of GCU. The result of Fault Tree Analysis (FTA) and fault diagnosis dictionary are used to determine the fault diagnosis model, thus can determine the fault detection points, reduce the complexity of diagnosis, and improve the efficiency of fault diagnosis.
