Detailed description of the invention
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in figures 1-8, the outside roll display device of vehicle running state, including power subsystem, display unit, graphics process list
Unit and detection input block, detection input block receives the signal of telecommunication that vehicle control system sends, and converts thereof into numeral letter
Number, it is sent to Graphics Processing Unit and carries out segmentation and the driving process of figure, the digit pulse letter that Graphics Processing Unit will export
Number being sent to display unit, make display unit send accordingly and warn figure, power subsystem passes through power supply changeover device and vehicle mounted electric
Source is connected.The DC voltage stability of the 18-32 volt of vehicle is reduced to the voltage needed for this device by power supply changeover device, and supply is each
Individual electricity consumption part, blood pressure lowering mode uses the mode of DC inversion.
Graphics Processing Unit is single-chip microcomputer and dot matrix screen driving, and single-chip microcomputer receives what each analog quantity was formed through analog digital conversion
Digital signal, is formed the driving signal of row and column, is exported by decoder through data dividing processing, and pulse signal is put by electric current
The big display unit driving respective color, forms dynamic color graphics；Single-chip microcomputer is AT89S51 type single-chip microcomputer, it is achieved to aobvious
Showing that the figure of unit, color are split, the data transmitting detection input block process.Fig. 7 is single-chip microcomputer internal junction
Composition, the I/O mouth abundant with it and external equipment can realize the figure to dot matrix screen, color is split, at data
Reason.
Detection input block, including photoelectrical coupler, analog-digital converter, A/D converter ic, photoelectrical coupler is by car
The analogue signal that control system sends (right turn signal 1, left direction signal 2, GES 3, brake signal 4, astern signal
5) it is converted into the corresponding signal of telecommunication, then converts the electrical signal to digital signal by analog-digital converter, be sent to single-chip microcomputer, light
Interference between the digital signal that the signal of telecommunication of electric coupler isolation vehicle input and analog-digital converter send.
Display unit is highlighted full color LED display screen, and LED display is by multiple regularly arranged light-emitting diode group
Becoming, corresponding luminous point is that color is by light emitting diode Surface Mount technical controlling by the high-low signal driven for emitting lights of row and column.Figure
In 3, the part of black round dot lights luminescence, and color can be monochromatic, can be double-colored or secondary colour, advanced luminescence
Diode Surface Mount technology can allow a luminous point can demonstrate Shan Hong color, single blueness green, single, even demonstrates the white of mixing
Color；Corresponding luminous point is by the high-low signal driven for emitting lights of row and column, and color is also controlled.Fig. 4 is that display screen is luminous
Schematic diagram, as a example by monochromatic luminescence, when Y1 end product are high level, when X0, X1, X2, X3 have a port to be low level, accordingly
The light emitting diode of intersection point just can be luminous, when port Y and port x have different pulse signals alternately, and sending out of its cross point
Optical diode is the most luminous, and when continuously pulse is added to lattice display, display screen just can demonstrate word, letter or figure
Shape, when a point is made up of three kinds of light emitting diodes of RGB, corresponding control signal can allow single LED lighting, group
Being combined is exactly a colored hair luminous point, and multiple points are luminous, just one image of composition.

As shown in Figure 10, the outside roll display device of vehicle running state also includes acousto-optic warning unit, acousto-optic warning unit with
The satellite interface of this display device is connected, and is used for pointing out human pilot and pedestrian；Acousto-optic warning unit is buzzer.Other structures
With embodiment 1.
As shown in figure 11, the display screen of the present invention being arranged on both sides before and after vehicle, quantity can be according to vehicle size
Fixed.As can be respectively installed one at lamp before and after electric motor car, (bicycle respectively installs one after needing to install former car Circuits System front and back
Individual), car can respectively be symmetrically installed two in lamp (headlight and brake lamp) place front and back, bus, truck, school bus, engineering truck etc.
Oversize vehicle can respectively install four or multiple, it is necessary to vehicle side also can install, can be according to road driving car
Size and speed reasonable installation, it is simple to identify.
Color employing three kinds of colors white, red, yellow that the display screen of the present invention shows:
(1) when the engine starts, display screen light lights, and color is that white arrow does not rolls；
(2) when the vehicle is running, arrow starts to roll, and the rolling speed of arrow can keep consistent, soon with the velocity of rotation of wheel
Then fast, the slowest；
(3) when touch on the brake car time, scroll arrow can become red, and rolling speed also keeps synchronizing consistent with vehicle wheel rotational speeds；
(4) when turning, before and after turning side lamp be yellow roll, the direction of arrow point to turning side, rolling speed also and
Vehicle body turning speed synchronizes；
(5) when waiting red light, either pulling the hand brake or touch on the brake, scroll arrow is all that redness does not rolls；
(6) when the vehicle is moving in a forward direction, front display screen arrow scrolls down through, and rear display screen arrow scrolls up, during reversing
Roll the most round about, keep consistent with vehicle wheel rotation direction；
(7) when keep to the side temporary storage time can symmetrical flicker before and after little area yellow light；
(8) can select to close according to parking place when parking for a long time.
The brightness of display screen changes along with the change of external environment condition, cloudy day or night display screen will be dimmed, daytime is fine
It display screen will brighten, and other people can be allowed to see, can not sting again other people eyes.The rolling speed of scroll arrow, face
Color and direction image the speed representing wheel rolling and direction, also represent travel speed and the direction of this car simultaneously.
The outside roll display device of the vehicle running state that the present invention provides, it is not necessary to change existing light on vehicle and set
Meter, but can install additional on this basis, coordinate and complementary use.After technology maturation also can both and with installing in a lamp,
Upgrading is reequiped in development also dependent on road practical situation or electroporation, thus reaches best visual effect.
It is to be understood that, above example is only presently preferred embodiments of the present invention, not in order to limit the present invention, all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the protection of the present invention
Within the scope of.
