At present, vehicle audio can be all installed in general automobile, for playing music or navigation hint, but present
Vehicle audio is substantially regulation volume manually, and this volume can be always maintained at after volume adjusting is good；If now in-car people
When needing to link up chat, volume can only be turned down manually, and volume is heightened manually again after waiting chat, it is troublesome in poeration.It is and existing
Vehicle audio function is single, can not meet use demand.
The content of the invention
It is an object of the invention to provide it is a kind of can be according to the car audio system of environmental volume automatic regulating volume.
To reach above-mentioned requirements, the present invention adopts the technical scheme that：A kind of car audio system is provided, including plays mould
Block, for playing audio-frequency information；Volume adjusting module, the volume played for adjusting the playing module；Sound sensor
Device, for gathering the voice signal in automotive environment；Audio-frequency fingerprint identification module, for what is collected from the sound transducer
Sound, explosive sound and sound of seeking help that people's one's voice in speech, vehicle audio play are identified in voice signal；Onsite alarming module,
For sending alarm signal at automobile end；Remote alarming module, for sending alarm signal to remote monitoring end；Control module,
With the playing module, volume adjusting module, sound transducer, audio-frequency fingerprint identification module, onsite alarming module and long-range report
Alert module electrical connection, and control the playing module, volume adjusting module, sound transducer, audio-frequency fingerprint identification module, scene
Alarm module and remote alarming module work.
Preferably, the car audio system also includes being used for the temperature sensor for gathering automotive interior temperature, TEMP
Device electrically connects with the control module.
Preferably, the car audio system also includes being used for the carbon dioxide sensing for gathering automotive interior carbon dioxide content
Device, carbon dioxide sensor electrically connect with the control module.
Preferably, the car audio system onsite alarming module includes buzzer and indicator lamp, and buzzer is arranged on roof,
Indicator lamp is arranged on automobile head, the tailstock and car door.
Preferably, the car audio system remote alarming module includes data transmission module, data transmission module with it is described
Control module electrically connects.
Compared with prior art, the present invention has advantages below：
(1) sound transducer, voice signal that can in real time in collecting vehicle are set, and known by audio-frequency fingerprint identification module
Do not go out the sound of people's talk, so as to adjust the volume of vehicle audio according to whether people speaks, automaticity is high, uses
It is convenient；
(2) explosive sound and emergency sound of in-car can be identified by audio-frequency fingerprint identification module, passes through onsite alarming mould
Block and remote alarming module are alarmed, and safety coefficient is high；
(3) temperature sensor and carbon dioxide sensor are set, vehicle interior temperature and carbon dioxide content can be detected in real time,
Alarmed when superscalar data, safety coefficient is high.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding of the present application, the part of the application is formed, at this
Same or analogous part, the schematic description and description of the application are represented using identical reference number in a little accompanying drawings
For explaining the application, the improper restriction to the application is not formed.In the accompanying drawings：
Fig. 1 is the block schematic illustration of the present invention.
Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with drawings and the specific embodiments, to this
Application is described in further detail.For the sake of simplicity, eliminate that well known to a person skilled in the art some skills in describing below
Art feature.
As shown in figure 1, the present embodiment provides a kind of car audio system, including playing module, for playing audio-frequency information；
Volume adjusting module, the volume played for adjusting the playing module；Sound transducer, for gathering in automotive environment
Voice signal；Audio-frequency fingerprint identification module, for identifying that people says in the voice signal that is collected from the sound transducer
Sound, explosive sound and the sound of seeking help that sound, the vehicle audio of words play；Onsite alarming module, for sending alarm at automobile end
Signal；Remote alarming module, for sending alarm signal to remote monitoring end；Control module, adjusted with the playing module, volume
Module, sound transducer, audio-frequency fingerprint identification module, onsite alarming module and remote alarming module electrical connection are saved, and controls institute
State playing module, volume adjusting module, sound transducer, audio-frequency fingerprint identification module, onsite alarming module and remote alarms mould
