The system that knocks into the back is prevented in a kind of fore-aft vehicle prompting based on visible light communication technology
Technical field
The present invention relates to automobile anti-rear end collision field, and in particular to a kind of fore-aft vehicle based on visible light communication technology is pointed out
The anti-system that knocks into the back.
Background technology
In existing automotive lighting and whistle control system, when driver's brake pedal, brake lamp switch is closed
Close, then the braking taillight of automobile and high-mount stop lamp are lighted;When driver stirs turning indicator control, then steering indicating light is accordingly bright
Rise;When driver is linked into reverse gear i.e. BLS and closes, then back-up lamp is lighted.The lighting of different car lights represents different
Lamp shows language.
Two cars before and after normally travel, the difference that the afterbody lamp group of front truck can be according to driver to vehicle signal lamp switch
Operation shows that different signal lamps are lighted.But, described lamp is only controlled by independent switch amount, and information content is single, it is impossible to comprehensive
The basic transport condition of automobile is closed, is that rear car driver provides more fully information.Meanwhile, the lamp only has two shapes of on and off
State, the alarming effect for providing is not good enough, it is impossible to be effectively prevented from the generation of traffic accident.Finally, traditional lamp light control system is many
Using relay or independent switch Schema control, this causes in-car wire harness excessive and connects up complicated, the electricity that system can be caused serious
Magnetic disturbance, makes the reliability decrease of system.
Meanwhile, if preceding vehicle is more, or above has oversize vehicle, may result in the feelings that cannot see traffic lights
Condition.
Content of the invention
For solving the above problems, the invention provides a kind of fore-aft vehicle prompting based on visible light communication technology is anti-knocking into the back
System, by the spacing of visible detection target vehicle, the color of road traffic, indicates setting for poster by automobile tail light
Put, and the lamp indicating language by tail-light before the identification of camera group, the anti-purpose for knocking into the back is reached, while also so that driver can
To recognize road conditions.
For achieving the above object, the technical scheme that the present invention takes is:
The system that knocks into the back is prevented in a kind of fore-aft vehicle prompting based on visible light communication technology, including
One light level array, installed in headstock, including 1-10 color sensor, for detecting the car of target vehicle
Away from the color of, road traffic, concurrent censorship measurement information;
Camera group, for gathering the image information of the lamp indicating language of front tail-light, and sends image information;
Automobile tail light control module, for controlling the flicker frequency of automobile tail light;
Data processing module, for processing road traffic information and the spacing that light level array detection is arrived, is transferred to
Automobile tail light control module, and the image information that before processing tail-light flicker frequency and camera group are gathered and sent, Ran Hou
Show on man machine operation interface;
Lamp shows state control circuit, and the information after processing for receiving data processing module is according to opening that information control lamp shows
Dynamic and closing, and select lamp indicating language;
Display module, on automobile tail light, for display lamp indicating language;
Lamp indicating language storage module, for storing the data of lamp indicating language;
Data update module, for entering in portable lighter indicating language storage module data more by approach such as internet, wifi
Newly;
Man machine operation interface, for input information call instruction and shows spacing that light level array detection arrives, red green
Lamp situation, the information data that front tail-light is passed over become digital information or traffic lights optical information, and the collection of camera group is concurrent
The image information for sending, and taillight working condition.
Preferably, lamp shows that state control circuit, using STC89C52 chip as main control chip, using 74HC595 chip is
Bootrom.
Preferably, the Human-machine Control interface adopts full color LED sign.
Preferably, multiple combined functions control button is provided with the Human-machine Control interface.
The invention has the advantages that:
By the spacing of visible detection target vehicle, the color of road traffic, poster is indicated by automobile tail light
Arrange, and the lamp indicating language by tail-light before the identification of camera group, drive comfort level and security is substantially increased, can be with shape
As intuitively display lamp shows that language provides the information warning of safety traffic for rear car driver, the anti-mesh for knocking into the back is can be simultaneously reached
's.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Accompanying drawing to be used needed for technology description is had to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, acceptable
Other accompanying drawings are obtained according to these accompanying drawings;
Fig. 1 is a kind of anti-system that knocks into the back of fore-aft vehicle prompting based on visible light communication technology of the embodiment of the present invention.
Specific embodiment
In order that objects and advantages of the present invention become more apparent, with reference to embodiments the present invention is carried out further
Describe in detail.It should be appreciated that specific embodiment described herein is not used to limit this only in order to explain the present invention
Bright.
As shown in figure 1, embodiments providing, a kind of fore-aft vehicle prompting based on visible light communication technology is anti-to be chased after
Tail system, it is characterised in that include
One light level array 2, installed in headstock, including 1-10 color sensor, for detecting target vehicle
Spacing, the color of road traffic, concurrent censorship measurement information;
Camera group 10, for gathering the image information of the lamp indicating language of front tail-light 1, and sends image information;
Automobile tail light control module 4, for controlling the flicker frequency of automobile tail light 1;
Data processing module 3, for processing road traffic information and the spacing that light level array 2 is detected, transmission
To automobile tail light control module 4, and the image information that before processing tail-light flicker frequency and camera group 10 are gathered and sent, so
Show on man machine operation interface 5 afterwards;
Lamp shows state control circuit 7, and the information after processing for receiving data processing module 3 controls lamp to show according to information
Start and close, and select lamp indicating language;
Display module 6, on automobile tail light 1, for display lamp indicating language;
