Problems solved by technology

Moreover, the existing aviation data recorder is very large in size. For example, after the plane crashes, the aviation data recorder is easily damaged. The degree of damage directly affects the integrity of the recorded data and whether it can be found and used safely.
In addition, the existing aviation data recorders are all installed on the head of the aircraft, and once the plane crashes, the head of the aircraft will land first, which further reduces the chance of finding the aviation data recorder after the plane crashes

Abstract

The invention relates to an intelligent aeronautical data recording instrument, which is characterized in that a main control MCU adopts a dynamic algorithm processing system to analyze and compress the aeronautical flight data which is collected by a flight data collection system and adopts a streaming media dynamic processing system to analyze and filter voice information which is collected by a voice collection system, and the aeronautical flight data and the voice information after being processed are transmitted into an internal memory card and a crash survival data protection system. The present aeronautical data recording instrument is upgraded to three data processing system, and a data backup system is added, so the possibility for searching the aeronautical data recording instrument after the airplane is crashed is further improved, and the service life of the memory hardware is prolonged, the working efficiency is improved; different feasible and reliable technical reports and market analysis reports are supplied for the maintenance of the airplane and the development of the enterprise by comprehensively managing the flight data through a local ground data center; and chip structure is adopted, so the size is greatly reduced, and the memory space is multiplied.

Description

[technical field] [0001] The invention relates to the technical field of instruments for recording aircraft flight data and voice information, in particular to an intelligent aviation data recorder mounted on an aircraft. [Background technique] [0002] At present, the function of the aviation data recorder (black box) loaded on the aircraft is very single, just a simple instrument for recording data and voice, and there is no information transmission structure and information transmission function in it. Once the plane crashes, the flight data and voice information recorded in it are stored in the black box, and the search and rescue personnel can only obtain the flight data and voice information of the plane by looking for the aviation data recorder on the plane, and the search for the aviation data recorder is A very cumbersome and complicated job. [0003] Secondly, the existing aviation data recorder adopts the disk storage structure, and its storage capacity is very l...
