某型无线电高度表原位检测仪的设计与应用

Design of In-situ Detector for a Radio Altimeter

无线电高度表是飞机上的重要导航设备,为了改善目前外场人工检测高度表效率低的情况,设计了原位检测仪。系统以ARM微处理器为核心,通过专用电缆对高度表的各种信号进行变换处理,得出检测结果。实践表明,采用该检测仪可以提高外场大约30%维护效率,并可有效防止人为误差的出现,具有良好的应用前景。

The radio altimeter is an important navigation equimeter for aircraft, In order to improve the in-situ testing case of low efficiency, designel the in-situ testing detector. The in-situ testing detector based on ARM microprocessor, transforms a variety of signal processing through a dedicated cable to the altimeter, then gets the testing result. Practice indicates that the detector, having a goodprospect, will not only improve the efficiency of about 30% of the felid maintenance, but also effectively prevent the emergence of human error.
