摘要
为便于维护网络化机载测试系统,及时定位测试系统故障,分析网络化机载测试系统架构及4种关键运行状态,设计一种基于关键运行状态实时监控的测试系统故障诊断方案,通过提取测试系统关键运行状态,利用遥测数据链路,实现测试系统关键状态实时监控及实时故障诊断。在某型飞机中进行方案验证,结果表明,该方案实现测试系统关键运行状态实时监控,能快速定位出测试系统故障。
In order to maintain the networked airborne test system conveniently,and locate some fault timely,the structure of the networked airborne test system and its four significant function status are analysed. A fault diagnosis scheme is designed,which is based on that the significant function status of test system can be monitored in real time. By extracting the significant function status and using the telemetry data link of the test system,real-time monitoring of the significant function status and fault diagnosis of test system is implemented. The scheme is verified in an airplane,and the result shows that the significant function status of the airborne test system can be monitored in real time,and some fault can be located timely.
