The invention belongs to the technical field of aircraft electromechanical comprehensive design, and particularly relates to an aircraft fire alarm detection and fault isolation system and method.The aircraft fire alarm detection and fault isolation system comprises a plurality of fire alarm detectors and further comprises a fire alarm detection box, and the fire alarm detection box comprises a self-inspection module, an isolation module, an alarm module, a decision module and an isolation switch; a plurality of isolation devices are arranged in the isolation module, the number of the isolation devices is the same as that of the fire alarm detectors, the isolation devices and the fire alarm detectors are connected in a one-to-one correspondence mode, the isolation module is connected with the judgment module through the isolation switch, the judgment module is connected with the self-inspection module, and the self-inspection module is connected with the isolation module and the alarm module. When a fire alarm occurs in an aircraft engine compartment, whether the alarm is a false alarm or a real alarm can be judged by reading engine parameters and other modes, and fault isolation is carried out.

    本发明属于飞行器机电综合设计技术领域,具体涉及一种飞行器火警探测与故障隔离系统及方法,系统包括若干个火警探测器,还包括火警检测盒,所述的火警检测盒包括自检模块、隔离模块、告警模块、裁决模块和隔离开关,所述的隔离模块内部设置有若干隔离装置,所述的隔离装置数量与火警探测器数量相同,且一一对应连接,所述的隔离模块通过隔离开关与裁决模块连接,裁决模块与自检模块连接,自检模块分别与隔离模块和告警模块连接,飞行器发动机舱出现火警告警时,可以通过读取发动机参数等多种方式判断该告警为虚警还是真实告警,并进行故障隔离。
