Abstract

The invention aims to solve technical problems of complicated operation, short recording period and so on for an airborne CVR recorder during application, and provides a method for acquiring cockpit voice record quickly. The method has the advantages of simple operation and long recording. The technical proposal adopted by the method comprises the following steps of: acquiring a voice source in a cockpit through a service platform and a remote electronic component and converting the voice source into an audio signal; then, accessing the acquired audio signal to a quick acquisition device in parallel through a transfer cable; performing audio conversion, analog-to-digital conversion and processing and coding encryption to the audio signal with the quick acquisition device; storing data into a memory card; taking out the memory card from the quick acquisition device, and inserting the memory card into a player for voice playback. The method has the advantages that longer voice period can be recorded; voice data with larger volume can be stored; the operation is simple, and the playback processing is convenient; meanwhile, the voice data can be encrypted to prevent voice information from leaking.

Description

technical field [0001] The invention relates to a voice recording device in an aircraft, in particular to a method for quickly acquiring cabin sound recordings. Background technique [0002] At present, in order to improve the quality of service and enhance the awareness of flight safety, some airlines need to assess the language used by the crew members in flight to standardize the language used by the crew members. At present, the only way to take is to disassemble the airborne CVR recorder after the flight (on modern commercial aircraft such as Boeing and Airbus aircraft, the Cockpit Voice Recorder (Cockpit Voice Recorder, referred to as the airborne CVR recorder) is indispensable There are few airborne equipment, and its main function is to analyze the causes of aircraft accidents. The cabin sound recorder loops to record various sounds in the cockpit of the aircraft during the flight for the last 2 hours or 30 minutes, including crew intercom, Land and air calls, audio...
