DME SELEX1119A型设备BCPS故障排查的分析和研究

Analysis and Research on BCPS Fault Trou-bleshooting of DME SELEX1119A Equipment

摘要: SELEX1119A型测距仪设备主要是用于民航的陆基导航设备，其功能是利用飞机与设备之间无线电信号传递的时间，计算飞机与导航台之间的斜距。其中BCPS是设备电源系统中的核心板件，其功能一方面是为发射机提供工作电压，另一方面为设备后备电池充电。本文将针对SLEX1119A型测距仪设备BCPS板件故障时的故障现象和原因进行深入分析，并对设备电池的配备进行优化。

Abstract: The DME SELEX1119A is mainly used as a land-based navigation equipment for civil aviation. Its function is to use the time of radio signal transmission between aircraft and equipment to calculate the slant distance between aircraft and navigation stations. Among them, BCPS is the core com-ponent of the device power system, which functions is to provide working voltage for the trans-mitter and charge the backup battery of the device. This article will conduct an in-depth analysis of the fault phenomena and causes of the BCPS board failure of the DME SELEX1119A, and optimize the equipment battery configuration.
