摘要
在某飞行器进行某项测试时,在地面测发系统发出点火信号后,出现某控制器未输出点火时序的问题现象。通过分析某控制器软件的工作方式,建立故障树,结合故障时的遥测数据,对该问题现象进行故障诊断,最终消除了故障。
During the test of an aircraft,the ignition timing sequence of a controller is not output after the ignition signal is sent by the ground detection and transmission system.By analyzing the working mode of the controller software,establishing fault tree and combining with the telemetry data,the fault diagnosis of this problem is carried out.
