Abstract
A kind of high-fidelity sound quality alarm of the electric vehicle with reminding turning function, it keeps increasing outside original anti-theft feature and turns to synchronous prompt sound function, including power module, alarm main control module, audio frequency power amplifier module, audio storage module, voice codec module, horn module and turn signal module.Alarm main control module, which is read, is stored in audio file in audio storage module, and the CPU of alarm main control module is by data buffer storage in RAM.When starting pole changer, alarm main control module receives signal and data is transferred to voice codec module from RAM, digital audio and video signals are converted into analog audio signal, send out the sound of steering moveable synchro light prompt after then being amplified by audio frequency power amplifier module by horn module.
Description
Technical field
The utility model belongs to electric vehicle anti-theft technical field, more particularly to a kind of electric vehicle with reminding turning function
High-fidelity sound quality alarm.
Background technology
As the improvement of people's living standards, Green Travel is advocated by people more and more, electric vehicle is in the nature of things
Become the most popular Green Travel tool of people, electric vehicle anti-theft device becomes the standard configuration of vehicle.
The type of current existing anti-theft device mainly has：
1, is mechanical：This kind of alarm is mainly the mechanical lock of headstock, wheel for locking electric vehicle etc., this anti-theft device
Cheap but entire anti-theft device is heavy, and key is easy to be replicated and pry open, and anti-theft performance is poor.
2, remote control alarming types：This kind of alarm is widely used in numerous electric vehicles, and electricity mainly is arranged by remote controler
Motor-car enters anti-theft state, and when electronic circuit detects that electric vehicle has vibration, alarm is sent out by loudspeaker or sound-producing device,
To frighten robber.
But the alarm sound sent out when existing distant control anti-theft alarming device burglar alarm is very single, ear-piercing, formation is made an uproar
Sound pollution.The steering sound that machinery is only sent out when existing steering gear turns to, to the prompt of surrounding, the effect is unsatisfactory.
Invention content
The utility model aim is the defect for existing distant control anti-theft alarming device, increases a kind of reminding turning function
Electric vehicle high-fidelity sound quality alarm.
The utility model to achieve the above object, adopts the following technical scheme that：
A kind of high-fidelity sound quality alarm of the electric vehicle with reminding turning function, it is characterised in that：It include power module,
Alarm main control module, audio frequency power amplifier module, audio storage module, voice codec module, horn module and pole changer signal
Module；
The turn signal module sends out turn signal information, and is transferred to the alarm main control module；
The audio storage module supplies the alarm main control module calls for storing audio file；
The alarm main control module is used to cache the audio file in the audio storage module, and according to pole changer
Signal audio file is exported to the voice codec module；
The voice codec module is transferred to institute for the digital audio file received to be converted into analog audio signal
State audio frequency power amplifier module；
The audio frequency power amplifier module is used to the analog audio signal received being amplified output to the horn module
It plays out；
The power module is powered for alarm modules.
It is preferred it is characterized in that：It is communicated and is connected by SPI between the alarm main control module and audio storage module.
Pass through dma mode data transmission between the alarm main control module and sound decoder module.
The alarm main control module model 7188.
The power module output voltage is Switching Power Supply 5V.
The utility model calls the HD Audio file in audio storage module as alarm sound, and sound is melodious dynamic
It listens.It is single and be distorted, the problem of being formed simultaneously noise pollution to solve existing safety device of electric vehicle sound.It is beaten simultaneously in driving
Open steering can not only remind below driving vehicle can also hear comfortable reminding turning sound, to user provide one more
Good atmosphere of riding.
Description of the drawings
Fig. 1 is the utility model principle schematic diagram.
Specific implementation mode
A kind of electric vehicle high-fidelity sound quality alarm as shown in Figure 1, including power module, alarm main control module 7188,
Audio frequency power amplifier module, audio storage module, voice codec module, horn module, pole changer signaling module.
Turn signal module sends out turn signal information, and is transferred to the alarm main control module；
Audio storage module supplies the alarm main control module tune for storing audio file, and by SPI communication modes
With.
Alarm main control module is used for the audio file in buffered audio memory module, and according to turn signal that audio is literary
Part is exported by dma mode to voice codec module.
Voice codec module is transferred to audio work(for the digital audio file received to be converted into analog audio signal
Amplification module.
Audio frequency power amplifier module is used to the analog audio signal received being amplified output to horn module and play out.
Power module is powered for alarm modules.
Audio file formats in audio storage module, including MP3, Flac, WAV, WMA, acc etc..
When utility model works, alarm main control module reads the sound being stored in audio storage module with SPI communications
Frequency file, the CPU of alarm main control module is by data buffer storage in RAM.When starting pole changer signal, alarm master control mould
Data information is transferred to voice codec module by block from RAM, digital audio and video signals is converted into analog audio signal, then by sound
The sound of reminding turning is sent out after the amplification of frequency power amplifier module by horn module.
