Speech collection and storage system and method

Abstract

The present invention belongs to the field of speech sound storage, and provides a speech sound acquisition and storage system, which comprises a speech sound acquisition transmitter and a speech sound storage manager, wherein the speech sound acquisition transmitter is provided for acquiring daily-operating speech sound information data of an aircraft, the acquired data is transmitted to the speech sound storage manager when the amount of the acquired data achieves the predetermined data acquisition amount, the predetermined data acquisition amount is at least several ten times the amount of the data acquired by the CVR installed on the aircraft, and the speech sound storage manager is provided for receiving the data acquired by the speech sound acquisition transmitter and calling a large capacity memory card to store the received data. The speech sound acquisition and storage system has characteristics of long record time, good economy, rapid data read, and easy maintenance.

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...

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
