Abstract
The invention can let car driver clearly hear the trumpet sound of other vehicles. It comprises: a sound pick-up, a signal processor and a speaker. On the four corners of car case, respectively mounts a sound pick-up connected to the signal processor of the car; the signal processor is formed by connecting signal amplifier to connect a A/D converter in series, and connecting the A/D converter to a multi-path filter in series, and then connecting a D/A converter, an amplifier to speaker.
Description
Technical field
The present invention relates to that a kind of to be used for all kinds of car steerings indoor, can monitor the device of other horn of motor vehicle sound, belong to the Manufacturing Technology for Automotive Parts field.
Background technology
At present, China has entered the automobile superpower ranks, and numeral shows according to the relevent statistics, and the current people directly relevant with automobile of China just reaches 1,200,000,000 more than.And all will just reach 500,000,000 1 thousand ten thousand with autoist by bus every day, and along with the acceleration of China's modernization, with increasing, the problem of Chan Shenging is also more and more thereupon to people's influence power for automobile.It mainly is the safety issue of car steering.The factor that causes automotive safety has a lot, wherein, when vehicle is exercised under the state that vehicle window closes, noise in the driver's cabin adds the ambient noise such as from outsidely make an uproar, wind is made an uproar of getting on the bus, make the driver very likely can't hear the tucket that other vehicles send, can't make right judgement and processing, cause unsafe factor, even cause severe traffic accidents.Particularly on highway.Present many drivers remind the driver in the place ahead with the method for flicker headlight when overtaking other vehicles, rather than warn with loudspeaker, one of its reason, and most of motor vehicle almost be can't hear in the good car of the other side's tucket, particularly sound insulation.And the intensity of caution effect and the daylight of flicker headlight and driver's attentiveness and lime light are relevant.How under the condition that does not increase the loudspeaker volume, can allow the driver in the car can clearly hear the tucket that the other side's automobile sends, can isolate other pass-by noise again, be current urgency problem to be solved.
Summary of the invention
The objective of the invention is to reduce the traffic accident incidence in order to strengthen travel safety, the spy provides a kind of car steering indoor other horn of motor vehicle sound monitoring device.This device not only can be so that the driver under any circumstance can both clearly hear the tucket that other vehicle sends, but also can realize reducing on the whole the decibel of tucket, reaches the purpose that reduces road traffic noise.
The present invention solves the technical scheme that its technical problem mainly takes: indoor other horn of motor vehicle sound monitoring device of a kind of car steering, mainly be by pick-up, signal processor (comprises amplifier, A/D converter, band pass filter, D/A converter) and loud speaker three parts composition.Its technical characterictic is: on four angles of automobile case car face portion, a pick-up 1 is installed respectively, and with place car in signal processor 2 be connected (Fig. 2); This signal processor 2 is by a signal amplifier 4 serial connection A/D converters 5, A/D converter 5 is connected in series with multichannel band pass filter 6 again, is connected in series 7, one amplifiers 4 of a D/A converter again; Connect loud speaker 3 at last.When other motor vehicles sent tucket, tucket was by pick-up entering signal processor.Because the speaker sound signal is an analog signal, in transmission course,, therefore be connected in series the intensity of signal amplifier 4 amplifying signals because distortion and decay always take place in the loss of interference of noise and energy.Through the A/D converter 5 of speaker sound signal by being connected in series with amplifier 4 of amplification,, amplitude also continuous speaker sound analog quantity continuous the time is converted to also discrete digital signal of time discrete, amplitude afterwards.At this moment,, be connected in series an amplifier 4 again, play back by loud speaker 3 through filtered speaker sound at last with amplifying signal power through the multichannel band pass filter 6 that is connected in series with A/D converter 5 of digital signal after the A/D conversion by pre-setting.Automobile in the process of moving, when other motor vehicles sent speaker sound, because the pick-up of this monitoring device is to be placed in respectively on the vehicle body four direction, it was clear as to tell the source direction of tucket therefore to be positioned at driver's energy of driver's cabin.Simultaneously, because the difference of the brand of automobile, model etc. might cause speaker sound frequency difference, therefore designed filter is the band pass filter of many passbands, to be applicable to dissimilar car horn sound frequencies.This monitoring device pick-up partly is installed in the automobile case, and bores some apertures at installation pick-up car shell position, so that collected sound signal, signal processor and speaker portion place a box jointly, are installed on optional position in the driver's cabin.This monitoring device is provided with switch and volume adjuster, so that the driver can use this device according to the needs of oneself.
Beneficial effect of the present invention comprises two aspects: one, when vehicle travels, perhaps when the driver is in fatigue driving, can effectively remind the trend of travelling of other vehicles of driver under vehicle window closes situation, and avoid taking place traffic accident; They are two years old, after this device is installed, under any circumstance the driver just can clearly hear the tucket of other vehicles in driver's cabin, therefore can consider suitably to reduce on the whole from now on the decibel of tucket, thereby reduces the noise pollution that honk brings to the city.
Description of drawings
Below in conjunction with drawings and Examples apparatus of the present invention are described further.
Accompanying drawing 1 speaker sound monitoring device installation site schematic diagram.Among the figure: 1. pick-up, 2. signal processor, 3 loud speakers.
Accompanying drawing 2 pick-ups are at the distribution map at four angles of automobile case car face portion.
The structural representation of accompanying drawing 3 apparatus of the present invention.
The signal processing flow figure of accompanying drawing 4 apparatus of the present invention.4. amplifiers among the figure, 5.A/D transducer, 6. band pass filter, 7.D/A transducer.
Embodiment
The present invention is made up of pick-up 1, signal processor 2 and loud speaker 3 three parts, and its position relation as shown in Figure 1.A pick-up 1 is installed respectively earlier on four angles of automobile case car face, and any part is installed signal processor 2 and loud speaker 3 in car then.Wherein signal processor and loud speaker place a box jointly.When automobile in the process of moving, when other vehicles send tucket, this sound can be by pick-up input signal processor, earlier through the amplifying circuit amplifying signal, be analog signal conversion digital signal by ADC then, through band pass filter filtering other noises except that the speaker sound signal, by DAC digital signal be converted to analog signal more then, amplify its power by amplifier, go out filtered speaker sound by loudspeaker plays at last.
Claims (2)
