Aviation audio player and aviation alarm system

Abstract

The invention discloses an aviation audio player and an aviation alarm system. The aviation audio player comprises a CPU (Central Processing Unit) module, an audio decoding module, a power supply module, an audio pre-recording module, an audio storage module and an alarm detection sensor module, wherein the audio pre-recording module and the audio storage module are used for inputting audio files into the audio decoding module respectively; the alarm detection sensor module is connected with the CPU module, and is used for detecting flight state parameters through an alarm sensor and inputting the flight state parameters into the CPU module for analysis; the CPU module is used for outputting a corresponding audio file reading instruction to the audio decoding module according to an analysis result of the flight state parameters; and the audio decoding module is used for reading the audio files according to the audio file reading instruction sent by the CPU module, and decoding the audio files. Through the aviation audio player, an audio playing function is realized, the aim of making alarms can be fulfilled without any peripheral complex system, direct and rapid multi-channel decoding control is realized, and the delay time is shortened.

Description

technical field [0001] The invention belongs to the technical field of avionics, and in particular relates to an avionics audio player and an avionics warning system. Background technique [0002] During the cruising process of large civil aviation transport passenger planes, for the sake of transportation safety, various warning signals may be generated. These warning signals will remind and warn passengers through broadcasting, such as decompression warning, turbulence reminder and other passenger reminders. The traditional warning method is realized through a special warning system or the manual operation of the flight attendants. However, the special warning system has a complex structure, and the manual operation is often difficult to meet the needs of rapid response. [0003] On modern civil aviation transport passenger planes, audio players are basic equipment, and all mainstream aircraft (Boeing, Airbus, etc.) are equipped with these audio players. These audio player...

AI Technical Summary

Problems solved by technology

Some existing automatic assistance methods only rely on the aircraft pressure system, and transmit the warning signal to the audio player through complicated line connections and offline buses, so that the airborne broadcast system can automatically play the audio of automatic pressure relief to remind passengers; but Such a system will bring difficulties to aircraft maintenance. During the maintenance process, test operation errors and system failures often occur, for example, causing hundreds of oxygen masks on the entire aircraft to be misplaced.
