故障モニタ装置を提供することを目的としたものである
。This invention solves the above-mentioned problems of conventional devices, and provides a fault monitoring device that does not take up much space, improves maintainability, and can be used by pilots during flight if necessary. It is intended to.
［問題点を解消するための手段］
この発明に係る故障モニタ装置は、各ＬＲＵからの故障
信号を半導体メモリに、ＬＲＵごとに対応する番号で。[Means for Solving the Problems] A fault monitoring device according to the present invention stores a fault signal from each LRU in a semiconductor memory with a number corresponding to each LRU.
記憶させて、一定時間間隔で該当ＬＲＵ及び搭載場所を
表示（コード化表示又は略語式表示）することにより。By storing the information and displaying (coded display or abbreviated display) the relevant LRU and mounting location at fixed time intervals.
複数のＬＲＵの故障表示ができ、スペース上の問題及び
故障ＬＲＵの迅速な識別を可能にしたものである。It is possible to display failures of multiple LRUs, allowing space problems and quick identification of failed LRUs.
［作用］
