Description
Affiliated technical field
The utility model relates to and a kind ofly shows the device of train signal with LED, can clearly, clearly indicate various intentions such as automobile driver is overtaken other vehicles, turned to, reversing.
Background technology
At present, the LED signal display apparatus that is applied to self-propelled vehicle is to adopt monolithic processor controlled monochromatic indicating device, this indicating device adopts the multirow LED of delegation or the synchronous light on and off of every row (still to be equivalent to single file, just width, brightness increase to some extent) read-out, mainly show brake and not too clear and definite the turning to of implied meaning.Color, line number and function single determined it can't indicate the various drivings intentions of chaufeur with the multiple figure of different color clearly.Such as, when indication turned to, the one section straight line that utilizes monochromatic LED to form was compared with the figure that the rocket type of the triplex row LED composition with two kinds of colors moves, and the definition of shown purpose and readability are obviously not enough; More there are not functions such as demonstration is overtaken other vehicles, reversing.In addition, present automobile-used indicating device utilizes red luminotron (because more eye-catching at fine weather ruddiness), compares demonstration clearly so can't use gold-tinted easily instead in the greasy weather.Therefore, though existing automobile-used LED telltale still has many deficiencies in the use than improving to some extent in the past.
Summary of the invention
Use novel a kind of indicating device that provides for overcoming existing automobile-used LED indicating device at the not unabridged version of function and aspect of performance, no matter at fine day still in the greasy weather, no matter be daytime or night, can both indicate the various driving intentions of automobile driver clear, clearly.
The technical scheme that the utility model adopted is: LED color 2 D display screen for graphic presentation and detection, control circuit and self-propelled vehicle science, reasonably combine, enable more ideally to indicate various train signals.Used microcontroller circuit of the various train signals of its Detection ﹠ Controling and power supply as shown in Figure 2, the used circuit of LED color 2 D display screen for graphic presentation is as shown in Figure 3.Relation between the each several part circuit as shown in Figure 1.
In view of the driving of automobile driver intention must reflect by each signal lamp switch, therefore, the state of signal lamp switch as the foundation of judging the driver drives vehicle intention.Because the level of motor vehicle signal lamp control system commonly used and the operation level of micro controller system are inconsistent, in frame of broken lines shown in Figure 2 (1) detection and control circuit, have expanded level shifting circuit between the detection pin of micro controller system and each the signal lamp master cock.And, be divided into serial connection and be not connected in series two kinds of situations of Der Blink und Abblendschalter according to the vehicle signal lamp control circuit, the signal lamp switch signal level shift circuit also is divided into two classes.
One class is that the signal lamp master cock level of serial connection Der Blink und Abblendschalter is changed.Because the existence of Der Blink und Abblendschalter, signal lamp master cock level is current variation low when high with the timing break-make of Der Blink und Abblendschalter, promptly can't be merely with the break-make of high and low definite switch of switch level.The utility model is for utilizing ' human eye is the most responsive for mobile object ' these characteristics, and the direction that the shape of a part of display graphics and figure are moved is consistent, makes it have comparison visual indication effect.This need be at signal lamp indicator cock period of contact, and what the maintenance figure moved is continuous, steady, not with the switching of Der Blink und Abblendschalter not off and on.For judging the state of signal lamp indicator cock timely and accurately, the utility model setting ' reference signal level change-over circuit ' is done the mode of reference mutually with the switch ends level, determines the break-make of switch.
Form left-hand rotation reference signal level change-over circuit with diode D1, resistance F1, zener diode Z1, specifically be connected to, the negative pole of D1 switches through to the contact of switch S 1 L, and the D1 positive pole connects the common point of F1 and Z1 and 33 pin of micro controller system U20, the other end power connection VCC of F1, the positive ground of Z1.

The similar circuit of being made up of diode D1, resistance F1, zener diode Z1 of this class circuit working principle, the factor of just dispeling Der Blink und Abblendschalter gets final product.Just can represent conducting and shutoff with its level of sending to inductive switch.
In each level shifting circuit, all optional 3.4 volts of stabilivolts of Z1-Z7.In the practical application, Z1-Z7 also should electric capacity in parallel, strengthens antijamming capability.
Above-mentioned is the level shifting circuit that is provided with at several baseband signal signal controlled switches that self-propelled vehicle has.Can set up and be similar to the signal level shift circuit of forming by D5, F5, Z5, or by D2, F2, Z2, D3, F3, common (the band Der Blink und Abblendschalter) signal level shift circuit formed of Z3 also need self-propelled vehicle to give micro controller system with certain on-off signal that LED shows.
In addition, also can reuse each switch of certain switch or comprehensive application and produce new control signal.
Detectability according to micro controller system, can original shows signal not produce under the situation of material impact self-propelled vehicle, by repetitive operation or two (or several) switch combination operations to existing switch on the car, the control signal that derivation makes new advances is given micro controller system, and then demonstrates the indicator signal that the original signal system can't show clearly or can't show at all.As, any moment after switch S 1 is connected the L point, within 1 second (under the normal circumstances, be enough to make chaufeur that pole changer is finished the operation required time twice) get to scram position and return the L point again,---becoming inconsistently by level is consistent, is that height identifies since 33 pin again---promptly can be considered the actv. signal of overtaking other vehicles during this, to deliver to the respective change of level on micro controller system 33,35 pin, the demonstration that begins to overtake other vehicles is turn-offed until the left-hand rotation switch.For another example, show turn to during, with Fog-proof light switch connection once (time was less than 0.5 second) when disconnecting immediately, micro controller system can be considered as reversing end for end signal to detected this positive pulse of 38 pin.

Embodiment 1: show left rotaring signal
When the A of pole changer S1 point and L point rigidly connect when logical, Der Blink und Abblendschalter is in conducting state, and the left-hand rotation lamp is bright, and L point current potential is near E, and E＞VCC, so D1 ends, to ground, the voltage stabilizing value of Z1 is given 33 pin of micro controller system U20 to the electric current of VCC through F1, Z1.Micro controller system detects this high level signal, then goes to carry out " turning left to show " program, is relatively delivered to the level of 33 and 35 pin simultaneously constantly by L point and A point.
Based on Fig. 4 read-out, it demonstrates the rocket shape figure indication left-hand rotation that constitutes as black disk among Fig. 5 to establish Single-chip Controlling.Three black disks of rocket shape figure first row show that with red light emitting diodes five black disks of second row show that with green three black disk red display of the third line allow figure be moved to the left from the right of car.
Micro controller system carries out following operation and finishes the move to left process of figure of above-mentioned demonstration: send two byte datas by serial port, 1 pin of control single chip computer is exported a positive pulse then, two byte datas that serial port is sent are exported on the 5-20 of IC11-1 pin, make 18,19,20 3 pin conductings, the 14th, 15,16 3 red light emitting diodes of corresponding diagram 5 first row are lighted; Equally, micro controller system is sent two byte datas again, positive pulse of 3 pin of control single chip computer output makes 14,15,16,17,18 5 pin conductings of IC21-1 then, and the 10th, 11,12,13,14 5 green LEDs of corresponding diagram 5 second row are lighted; Micro controller system is sent two byte datas again, and positive pulse of 5 pin of control single chip computer output makes 18,19,20 3 pin conductings of IC31-1 then, and the 14th, 15,16 3 red light emitting diodes of corresponding diagram 5 the third lines are lighted.More than half part middle row was for green before the light-emitting diode that triplex row is lighted had constituted, and back smaller part part is the rocket shape figure of two behavior redness up and down.
Delay time 10 milliseconds and (can be set this time flexibly, the speed that moves with the sensation figure is suitable for suitable), micro controller system repeats aforesaid operations, just the data of sending are lighted the 13rd, 14,15 3 red light emitting diodes of first row, the 9th, 10,11,12,13 5 green LEDs of second row are lighted, and the 13rd, 14,15 3 red light emitting diodes of the third line are lighted.Contrast the position of last figure on read-out, this is equivalent to be moved to the left one.So, the light-emitting diode of each row luminescence segment high order end is lighted, and the diode of its low order end is extinguished, all shift out read-out until figure.Then, start anew whole process repeated again.So, give the sensation that rocket shape figure right-to-left moves circularly.This rocket shape figure itself can clearly indicate the driving intention of chaufeur, and figure moves along the rocket direction indication, has further strengthened display effect.
As long as 33 pin of U20 and the level of 35 pin are consistent, think that just left rotaring signal is effective, continue to show.Until detecting 35 pin that the A point makes U20 is high level, and the L point to make 33 pin of U20 be low level, just stop turning left to show.
Micro controller system detect left rotaring signal in 1 second by effectively becoming invalid and becoming again again when effective, then the operation display routine of overtaking other vehicles disappears until detecting left rotaring signal, promptly the level of 33 pin and 35 pin no longer is consistent.The display routine of overtaking other vehicles can be worked out as follows: on the basis that shows left-hand rotation figure shown in Figure 5, another rocket shape figure of increase that a CF has obvious difference, the speed that moves to left being accelerated obviously is (such as middle behavior yellow, two behavior redness up and down, size is short a little, and per 5 milliseconds are moved to the left one).In the two figure moving process a certain moment appear at simultaneously on the read-out figure as shown in Figure 6.The summary display effect is exactly, a rocket shape figure ring shift left, and another rocket shape figure circulates apace and surmounts it, can indicate visually and overtake other vehicles.
When micro controller system detects 37 pin and is high level, the V-arrangement pattern that the disk of black as shown in Figure 7 of display flashing is formed, the bottom of this pattern shows that with red LED two limits can be with yellow.Or inverted U-shaped read-out two vertically section show the flechette-type patterns that move down simultaneously, the indication reversing.
On the read-out of shape shown in Figure 4, can make each one section yellow led of two ends carry out demonstration bright, go out alternate (such as bright 300 milliseconds, go out 300 milliseconds, hocket) simultaneously.Inverted U-shaped read-out can make yellow led carry out bright, the alternate demonstration of going out simultaneously in the bottom of two vertical display segments; Or in the bottom of two vertical sections, it is luminous that the outside one row yellow led keeps, and a middle row yellow and an inboard row redness are continuously lighted one by one again and extinguished one by one.
Can be similar to and show bandwidth signals, just the diode of lighting be changed and do redness, and change the flicker of light and dark (such as bright 100 milliseconds, extinguish 20 milliseconds, because the afterglow characteristic of LED, human eye perceives is less than extinguishing fully, and only feeling has brightness to change) into.But do not pursue the demonstration that row are lighted.
When detecting 38 pin and be high level, the yellow led on the read-out can be lighted simultaneously, extinguished simultaneously, hocket at interval by certain hour.When needing during this to show other indicator signal, can increase the composition of sodium yellow in the shows signal by increasing pattern length or using the mode that yellow diode shows instead.Such as showing to turn left, the green that middle row when there be not mist can be shown changes yellow into; Demonstration is overtaken other vehicles, and changes yellow into except that front among Fig. 6 is moved the pattern middle row slowly, and the length with back rapid traverse pattern middle row sodium yellow increases again, and changes its top delegation into yellow, increases the penetrating capacity of pattern to mist.
On the read-out of shape shown in Figure 4, the rocket shape figure that the tune available horizontal of turning left direction right-to-left moves adds at (as shown in Figure 7) V-arrangement pattern of left end flicker and represents; On inverted U-shaped read-out, the rocket shape diagrammatic representation that the tune available horizontal of turning left direction right-to-left moves, move down after to the end again.The tune of turning right can copy the tune operation.
In addition, can show bandwidth signals, turn sign even comprise the Fog-proof light signal, on read-out, show simultaneously detected.
The utility model can produce such effect: the vehicle signal on off state detects promptly and accurately and the LED signal aspect and indication is clear, figure is succinct, implied meaning is clear and definite, and the people is come into plain view, and is very helpful for improving traveling security.The more important thing is that the utility model provides a vehicle signal display platform that extendability is more intense.No matter in the setting of level shifting circuit, still aspect the design of the detection of signal, read-out, the installation very wide development space is being arranged all.
