某型激光捷联惯导航线切换异常故障研究

Research of Abnormal Fault of a Laser Stra gation Line Switching odown

以某型激光捷联惯导航线切换异常故障为例,利用故障树方法进行问题定位,在此基础上对问题机理展开分析。通过试验实现了问题复现,准确定位了故障原因,提出了针对性修复措施,并最终验证了修复措施的有效性,使系统功能恢复正常。

Taking the route switching abnormal failure from a certain type of laser strapdown inertial navigation sys-tem as an example,this paper uses the fault tree method to locate problem,and then analyzes the problem mechanism.It reproduces the problem by experiment,pinpoints the cause of the problem,and puts forward the corresponding repair measures.Eventually,it is verified that these repair measures are effective which recovers the systme function.
