Description

technical field

[0001] The invention relates to the field of aviation, in particular to a voice collection and storage system and a method for voice collection and storage using the voice collection and storage system. 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 device to re...
