The invention discloses an undercarriage position indicating system and indicating method. The method comprises the following steps: acquiring signals acquired by a plurality of position sensors at each part of an undercarriage; performing OR operation on the analog-to-digital converted signals of the position sensors at the same part of the undercarriage to obtain a first indication result; and/or, carrying out AND operation on the signals, subjected to analog-to-digital conversion, of the position sensors located at different parts of the undercarriage to obtain a second indication result. An undercarriage lower position indicating result related to a safety class I failure event is connected with the indicating lamp box through a hard wire and is displayed, and meanwhile, an undercarriage position indicating result is connected with the comprehensive indicator through a bus and is displayed. The redundancy function is achieved, meanwhile, the requirement for independence is met, the system has the advantages of being simple in structure, high in reliability and high in safety, and a powerful guarantee is provided for accurate undercarriage position indication and aircraft flight safety.
本发明公开了一种起落架位置指示系统及指示方法,获取起落架各部位多个位置传感器采集的信号;对位于起落架同一部位的位置传感器的经模数转换后的信号进行或运算,得到第一指示结果;和/或,对位于起落架不同部位的位置传感器的经模数转换后的信号进行与运算,得到第二指示结果。安全性I类失效事件相关的起落架下位位置指示结果通过硬线与指示灯盒连接并显示,同时设有起落架位置指示结果通过总线与综合指示器连接并显示。本发明在实现冗余功能的同时满足了独立性的要求,且具有系统架构简单、可靠性高、安全性高的特点,为起落架位置指示准确及飞机飞行安全提供了有力保障。
