Description
Technical field
The present invention relates to the technical field of unmanned plane, particularly relate to a kind of unmanned plane recording system.
Background technology
At present, the unmanned plane that market uses does not has sound-recording function, makes police cannot listen within the very first time
The content that offender is talked about, affects the route of police.That sends out big fire goes to region, due to full of smoke, and on-the-spot energy
Degree of opinion is excessively poor, and existing unmanned plane does not has recording system, cannot judge whether scene has blast, affect disaster relief work,
Even can result in greater loss.Along with social development, the recording of unmanned plane is the most extremely important, and current unmanned plane is the most this
Function.
Summary of the invention
The technical problem to be solved is without the deficiency of sound-recording function for above-mentioned existing unmanned plane, it is provided that a kind of
Unmanned plane recording system.
For solving above-mentioned technical problem, the technical scheme that the present invention takes is: a kind of unmanned plane recording system, is used for realizing
The sound-recording function of unmanned plane, including: wave filter, power amplifier and memorizer, it is characterized in that: sound acquisition module and controller
Connect an AMRA pick up, the 2nd AMRA pick up, the 3rd AMRA pick up, sound decibel tester, an AMRA respectively
Pick up, the 2nd AMRA pick up, the 3rd AMRA pick up connects wave filter respectively, and wave filter connects power amplifier, power
Amplifier connects acoustic memory, and picture recording module connects video recording memorizer, acoustic memory and video recording memorizer connection sound respectively
Sound image synchronization module, audiovideo synchronization module connects output module.
The preferred version of such scheme is: a described AMRA pick up is high band pick up.
The preferred version of such scheme is: described 2nd AMRA pick up is Mid Frequency pick up.
The preferred version of such scheme is: described 3rd AMRA pick up is low-frequency range pick up.
The preferred version of such scheme is: described sound acquisition module and picture recording module must synchronize to carry out.
By the technical scheme of the invention described above, the recording flow process of a kind of unmanned plane recording system comprises the following steps:
(1) carry out sound collection, gather the sound that unmanned plane is to be recorded.
(2) measure sound decibel by sound decibel tester, sound between 40HZ～160HZ, controller distribution the
One AMRA pick up processes, and sound processes at 160HZ～2560HZ, controller distribution the 2nd AMRA pick up, and sound exists
More than 2560HZ's, controller distribution the 3rd AMRA pick up processes.
(3) filtering, is filtered the noise in sound by wave filter.
(4) power amplification, amplifies the power of sound by amplifier.
(5) carry out sound and video recording coupling, use sound and video recording to synchronize.
(6) sound and the output of video recording.
The present invention is just to use AMRA technology to carry out acoustic-electric conversion, AMRA technology and Advanced Micro balanced armature technology；Respectively
The sound of individual frequency range uses corresponding AMRA pick up to carry out acoustic-electric conversion, increases the reliability of acoustic-electric conversion；Unmanned plane is recorded
Circumstance complication, causes unmanned plane to record in flight course difficulty；AMRA technology has reliable and stable, small size, big volume, saves
The feature that electricity is energy-conservation, and there is extremely strong acoustic-electric translation function, can effectively realize the sound-recording function of unmanned plane.
Provide the benefit that: realize the sound-recording function of unmanned plane, good stability.
