Quick access to the cabin sound recorder and the method of cabin sound record acquisition

Abstract

The invention belongs to the field of aviation, and provides a QACVR which is arranged on an aircraft. The QACVR comprises a voice collecting transmitter and a voice storage manager. The voice collecting transmitter comprises a collecting module and a transmission module, the collecting module is used for collecting the voice information data of the normal operation of the aircraft, the transmission module is used for transmitting the collected data to the voice storage manager when the data collected quantity reaches a specific data quantity, the specific data quantity is at least tens of times of data collected by a CVR every time, and the CVR is arranged on the aircraft. The voice storage manager comprises a receiving module, a high-capacity storage card and a storage module, the receiving module is used for receiving the data collected by the voice collecting transmitter, and the storage module is used for calling the data stored in the high-capacity storage card and the data received by the receiving module. The QACVR is long in recording time, good in economical efficiency, fast in data reading, and convenient to maintain.

Description

technical field [0001] The invention relates to the field of aviation, in particular to a fast-acquisition cabin sound recorder and a method for obtaining cabin sound records by using the fast-acquisition cabin sound recorder. Background technique [0002] At present, the cabin sound recorder provided by major European and American aviation equipment manufacturers can record various sounds in the cockpit for the last 30 minutes or 2 hours. Since only the voice record reproduction needs during the aircraft accident are considered, only CVR (Cockpit voice recorder, cockpit voice recorder) is currently installed on the aircraft. At present, the only way that can be taken is to disassemble the airborne CVR each time, and to play back and transcribe through the special equipment on the ground. Because the design purpose of CVR is focused on accident investigation, it has natural defects in storage time, codec, reading speed, storage medium, etc. If airlines want to use this devi...

AI Technical Summary

Problems solved by technology

[0005] Decoding requires special equipment, long decoding time and complicated operation;

[0006] The effect of assessing crew members is not obvious, and only the voice content of the last 2 hours can be checked at most each time;

[0007] Cannot record cockpit communications and calls for more than two hours, which is not conducive to the post-mortem investigation of some accidents
