Specific embodiment
As shown in Figure 1, structurally, automobile tail light is by vehicle body lamp (region 1) and tail case cover lamp (region 2) two parts
Composition, two parts are made of LED dot matrix, and automobile tail light indication signal is by two sets of compound displays of LED dot matrix.
As illustrated in figs. 2-7, for from distribution of color, automobile tail light is made of three parts.Wherein, region 1 mainly by
The filling of 16 × 8 red LED lamps, is used as brake lamp, is lighted in braking automobile to communicate information to front vehicle, reminds rear vehicle
Is slowed down or stopped；Region 2 is mainly filled by 16 × 24 yellow LED lamps, and turn signal is used as, and reminds pedestrian and vehicle timely
It dodges, right-hand rotation, left-hand rotation, reversing, straight trip signal pattern are as shown in the figure；Region 3 is filled by 16 × 8 white led lamps, is used as rear mist
Lamp, back-up lamp, reversing automobile light back-up lamp when pattern is moved backward in display.
Analog control circuit simulates four straight trip, left-hand rotation, right-hand rotation and reversing signals using four buttons；Line driver electricity
Road selects 74HC154 chip, and connecting triode carries out Current amplifier after each of which output port；Row driver selects three pieces
74LS595 drives；Two pieces of LED display groups become an entirety to show three parts signal, the leftmost side and the rightmost side two
The dot matrix of block 16 × 8 is directly driven by single-chip microcontroller, and 16 × 24 intermediate dot matrix is driven by line driver and row driver
Dynamic, to show running signal, all LED dot matrix can only be lighted when anode is high level and cathode is low level pair
Answer the LED of position.
It is used to the LED display that the original light bulb of automobile tail light replaces with MCU driving to show various information.It compares
In single light bulb, LED can then be assembled into lattice LED display screen, be driven using single-chip microcontroller, for showing various patterns and letter
Breath；And LED the advantages of there are also low-voltage drivings, rises so can easily be driven with automobile storage battery without in addition adding
Volt circuit will not bring burden to the energy resource system of automobile.
The mode for lighting LED in practical applications has two kinds of sides of static drive display mode and dynamic scanning displaying mode
Method.
(1) static drive display mode:
No matter showing figure or text, as long as position phase of the control where with each point for forming these figures or text
Corresponding LED component shines, so that it may obtain display that we want as a result, side that is this while controlling each luminous point light on and off
Method is known as static drive display mode.Static state light the display mode LED luminance of LED display uniformly, stablize, be clear etc. it is excellent
Point, but static status display have the defects that it is very big.The dot matrix of 16x24 shares 384 light emitting diodes, and single-chip microcontroller is without so more
Port, if calculated come ECP Extended Capabilities Port by 8 latch using latch, the dot matrix of 16x24 needs 48 latches
Device.The cost of flower will be a very big number on latch.Therefore display screen in practical applications does not use nearly all
This design, and the display methods of dynamic scan is known as using another.
(2) dynamic scanning displaying mode:
The meaning of dynamic scan is briefly exactly to light in turn line by line, and such scan drive circuit can realize multirow
Same rank share a set of driver.For the 16x24 dot matrix used in the present invention, all shining with 1 column
The anode of pipe connects together, and the cathode of all luminous tubes with 1 rows is connected together (connection of common cathode), first sends out corresponding the
The data of a line luminous tube light on and off and latch, then gate the 1st and exercise it and ignite certain time, then extinguish；Second is sent out again
Capable data and latch, then gate the 2nd and exercise it and ignite the identical time, then extinguish；And so on, after the 16th row,
The 1st row is ignited again, repeatedly circulation.When the speed of such circulation is sufficiently fast (24 times per second or more), due to the vision of human eye
Persist phenomenon, it will be able to see figure stable on display screen.
The anode of 16 × 24 LED turn signal dot matrix display screen is connected with row driver, and cathode and line driver
It is connected, we drive Drive of row and column device by control single chip computer (such as AT89C51), and it gives row corresponding high level, gives column low level,
So corresponding LED will shine, and obtain the luminous pattern that we want.
When being shown using scanning mode, every a line has a line driver, and the same of each row ranks a shared driving
Device.Display data are stored in the memory of single-chip microcontroller, are discharged by the form sequence of 8 bytes.A line when display
In the data that respectively arrange all be transmitted to corresponding row driver up, the problem of this there is a display data transmissions.From control
The data transmission of circuit to row driver can use juxtaposition or serial mode.When using parallel mode, from control circuit
Number of, lines to row driver is big, and corresponding hardware number is more.When there are many columns, the scheme of parallel transmission is undesirable
's.Using the method for serial transmission, control circuit can get forwarded to column driving for column data one one only with a signal wire
Device, it is undoubtedly very economical in hardware aspect.But serial transmission process is longer, when transferring data to row driver, only when
Each column data of a line all for transmission to position after, this line it is each column could concurrently be shown.The display of a line in this way
Process can decompose queued data preparation (transmission) and column data shows two parts.For serial transmission mode, columns
May be considerably long according to time, the time of row display is left in the case where determining the line-scanning period with regard to very little, so that shadow
Ring the brightness for arriving LED.
In order to solve the problems, such as to influence brightness of display screen, i.e. time for showing of Data Preparation Process and data longer asks
Topic, the method that we can use overlap processing.In this line driver while lighting display screen, we transmit next line number
According to, thus can solve transmission the longer problem of data time.In order to achieve the purpose that overlap processing, it would be desirable to column drive
Dynamic device must have the function of latch, such as register 74HC595.
Column drive circuit is made of integrated circuit 74HC595.It enters with 8 bit strings and the shift register gone out and one
The structure of a 8 output latches, and the control of shift register and output latch be it is independent, may be implemented
While showing this raw column data, the column data of next line is transmitted, both achievees the purpose that overlap processing.
3 74HC595 are subjected to cascade, shift clock SCK and data latch signal RCK can be shared.In this way, when the
A line needs data to be shown that can all move into it in 74HC595 after 8x3=24 SCK clock, will also produce at this time
Data are latched in 74HC595 by a raw data latch signal RCK, and under the action of enable signal, make to seal in data simultaneously
Row output, so that field corresponding with each output bit driving tube be made to be in amplification or off state；Simultaneously by row scan control circuit
Generating signal is connected the first line scanning tube, and the anode for being equivalent to the first row LED all connects height, it is clear that the light on and off of the first row LED pipe
The latch signal being dependent in 74HC595；In addition, while the first row LED pipe is lighted, then is moved into 74HC595
Two rows need data to be shown, are then latched, while the first line scanning tube being closed by row scan control circuit and being connected
Second row lights the second row LED pipe, and so on, the first row is returned after the 16th row is scanned, as long as in this way, sweeping
It is sufficiently high to retouch speed, so that it may form the complete text of a width or image.
Horizontal drive circuit is made of 4-16 line decoder 74LS154 with transistor amplifier, and decoder 74LS154's is defeated
Entering is 16 ary codes, and decoded output is low state scanning signal, and in horizontal drive circuit, E1 the and E2 pin of 74LS154 is connect
Ground, then using tetra- foot of A, B, C, D as input terminal.It just will form 16 kinds of different input states, respectively 0000~1111, then
It controls every kind of state only to export all the way, that is, has the output of 16 tunnels.If 24 points of a line are all lighted, pass through 74LS154's
Electric current will reach 240mA, and in fact, 74LS154 decoder does not provide enough absorption electric currents while driving 24 LED same
When light, therefore, Ying 74LS154 per output end every a line corresponding with 16x24 matrix display all the way between with one three
Pole pipe amplifies current signal, in this way, corresponding triode emission is extremely high when a certain output pin of 74LS154 is low level
Level is to make the correspondence row of matrix display also be high level.
Other than conveying information with pattern, Chinese character can be used also to indicate, but with Chinese character indicate for car come
It has said a problem, has been exactly limited area at the taillight of car, Chu's word may not seen using Chinese character front vehicle, this point is in public affairs
Handing on the large cars such as vehicle is not problem.
With LED display instead of original automobile tail light after, new taillight can be used for following aspects:
(1) in China, the radix of car is very big, and in daily life, we on the way can often hear violent
Why whistle sound, trace it to its cause, and in the rightmost side lane of road, many through vehicles often block desired right-turning vehicles
Road, here it is the reasons for failing to transmit information in time, so these cars can use novel taillight instead.
(2) novel taillight can be used for the engineerings vehicle such as slag-soil truck, these vehicles are in the process of moving due to loading, and quality is very
Greatly, it will cause serious consequence in case of accident, it is possible to novel taillight is loaded onto, for prompting front vehicle to keep safety
Running distance, avoid accident.
