教练机综合CNI系统仪表着陆引导功能噪音问题排查

Troubleshooting for Noise from Instrument Landing Guidance Function of Trainer Integrated CNI System

本文介绍了教练机地面通电检查过程中,综合CNI系统仪表着陆功能异常输出莫尔斯码音频故障的排查和解决方法。通过模拟故障复现、对比测试定位故障原因为系统参数设置不合理,经对设备参数重新进行测试调整后,噪音消失,干扰问题解决。

This paper introduces the troubleshooting and solution of abnormal output of Morse code audio by the instrument landing function in integrated CNI system during ground power on inspection of trainer.Through simulation of fault recurrence and comparative test,it is found that the fault is caused by the unreasonable setting of system parameters.After the re-test and adjustment of the equipment parameters,the noise disappears and the interference problem is solved.
