故障树在无人机发射机故障诊断中的应用

Application of FT in Fault Diagnosis of UAV Transmitter

无人机发射机的电子设备组成系统复杂度高,各组成部分之间的影响因素复杂,在故障诊断过程中通常难以做到快速、准确定位。针对无人机发射机在故障诊断中的上述缺点,结合故障树诊断中的最小割集法,通过定量分析给出了一套常用的诊断流程,该诊断流程提高了诊断效率,可以用于发射机的快速诊断。

UAV transmitter is composed of the high-complexity electronic devices,between which the influence factors are complex,so it＇s often difficult to achieve the fault position quickly and precisely in the process of fault diagnosis.Aiming at the disadvantage above,a set of common diagnostic flow is offered by means of the minimal cut set method of fault tree diagnosis and quantitative analysis.The diagnostic flow improves the efficiency of diagnosis and can be used in the rapid diagnosis of the transmitter.
