The invention belongs to the technical field of civil aviation safety guarantee, and particularly relates to an aircraft emergency distress signal monitoring system and monitoring method. The monitoring system comprises a double-frequency signal monitoring device, an information comprehensive processing device and an alarm display device, wherein the double-frequency signal monitoring device can synchronously obtain two kinds of emergency signals and carry out corresponding processing such as decoding and preliminary judgment on the position of an involved aircraft; the information comprehensive processing device can correspondingly process information transmitted by the double-frequency signal monitoring device to obtain information such as the position and the identity of the involved aircraft; and the alarm display device can be used for preprocessing data transmitted by the information comprehensive processing device, including displaying alarm information. According to the aircraft emergency distress signal monitoring system and monitoring method, a localization technical means is provided, all-day real-time monitoring of the emergency signals is realized, the operation weakness of the existing Cospas-Sarsat in a specific scene is effectively supplemented, and the signal acquisition capability of weak signal analysis error codes or incapability of receiving analysis in anelectromagnetic interference environment is improved.
本申请属于民用航空安全保障技术领域,特别涉及一种航空器应急遇险信号监测系统及监测方法;监测系统包括:双频信号监测装置,能够同步获取两种应急信号,并进行相应的例如解码以及对涉事航空器的位置进行初步判断等处理;信息综合处理装置,能够对双频信号监测装置传输的信息进行对应处理,获得根据涉事航空器的位置、身份等信息;告警显示装置,能够对信息综合处理装置传输的数据进行预处理,包括将告警信息进行显示。本申请航空器应急遇险信号监测系统及监测方法中,提出本地化技术手段,不仅实现对应急信号的全天实时监测,有效补充了现有Cospas‑Sarsat的特定场景下的运行短板,提高了电磁干扰环境下弱信号解析误码或无法接收解析的信号获取能力。
