Abstract
A kind of different colours light colour display device of (real time) demonstration driving speed in real time of borrowing.This colour display device utilizes speed of vehicle detector to detect the vehicular transmission shaft rotating speed, and produces rotational speed pulse signal.Rotational speed pulse signal after the timer cut becomes the period pulse, by the umber of pulse of counter calculation interval pulse, supplies scrambler to produce corresponding preface sign indicating number by clock pulse signal.Driver makes corresponding light source cell conducting through the startup of preface sign indicating number.The light that the Different Light unit sends forms the light of different colours on the light curtain, so as to showing the driving speed of difference.
Description
The present invention relates to a kind of real-time colour display device for driving speed, particularly relate to a kind of device that shows driving speed with different colours light in real time.
The employed brake system of vehicle is to light tailstock red light when the driver depresses brake pedal at present, with the caution back car.Yet this alarm function that flashes the redlight merely often can't provide time enough that back car driver is taken appropriate measures.When especially two spacings were nearer, back car more can be because of braking not as good as causing overtaking collision or injury in various degree.Reason mainly is because brake lamp is bright too suddenly, and its information that may touch on the brake of car driver after any prompting is not arranged in advance.In other words, if front vehicles can be sent indication in advance to the speed-down action before its brake, then can reduce the loss that causes because of brake greatly.
Therefore, the objective of the invention is to disclose a kind of real-time driving speed display device, avoiding taking place above-mentioned injury and the loss that causes because of brake, and then ensure driver's safety of life and property.
For achieving the above object, real-time driving speed display device of the present invention shows in real time that with different colour lamplights the speed of a motor vehicle changes, and not only can warn back car in advance, also has decorative effect concurrently.
Real-time driving speed display device of the present invention comprises: by optical screen curtain and three groups of display boards that primary lights is formed; Be used for detecting the vehicular transmission shaft rotating speed and export the speed of vehicle detector of vehicle speed pulse signal; Produce the clock-signal generator of clock pulse signal; Make rotational speed pulse signal be become the timer of period pulse by the clock pulse signal cut; The counter of the umber of pulse of calculation interval pulse; The counter content encoding is become the scrambler of another serial preface sign indicating number; Convert serial preface sign indicating number the demoder of parallel preface sign indicating number to, and start and drive the driver of display board through parallel preface sign indicating number.In addition, device of the present invention also comprises brake detector, when stepping on brake pedal, produce brake and detect pulse to scrambler, the gap coding device continues the counter content is encoded, and directly produces specific preface sign indicating number by scrambler, to start driver, make display board send ruddiness.
Now with reference to accompanying drawing, content of the present invention and advantage are described in detail in detail with regard to an embodiment:
Fig. 1 is the circuit block diagram of the embodiment of the invention;
Fig. 2 is used for the oscillogram of key diagram 1 circuit;
Fig. 3 is the sketch map of display device structure in the key diagram 1;
Fig. 4 is the sketch map of display light source among Fig. 3;
Fig. 5 is used for illustrating the corresponding relation of driver pulse and light source.
At first, see figures.1.and.2 the explanation real-time colour display device for driving speed 10 of the present invention.Device 10 comprises detection part 20, control section 30 and shows part 40.Detect part 20 and comprise two kinds of detecting devices: revolution detector 21 and brake detector 22.Revolution detector 21 is used for detecting the rotating speed of vehicular transmission shaft and the pulse R of output expression rotating speed gives partly 30 timer (timing gate) 31 of control.Timer 31 can be and door (AND gate), makes pulse R become period pulse T by clock signal generator (clock generator) the 32 time clock C cuts that produced.Counter (counter) 33 is connected in the output of timer 31, to calculate the umber of pulse of this period pulse T, the counting of counter 33 just produces the serial preface sign indicating number corresponding to original rotating speed speed through after being attached thereto the processing of the scrambler (encoder) 34 that connects.This preface sign indicating number after demoder 35 is changed into parallel preface sign indicating number, starts demonstration part 40 again.
Show that part 40 comprises a plurality of drivers 41 and a display board 42.As shown in Figure 3 and Figure 4, display board 42 mainly is to be made of light source 43 and optical screen curtain 44.Light source 43 comprises three groups of primary lights, and every group can comprise one or several primary lights unit again.In this embodiment, light source 43 is primary lights unit R of 3 * 3

3Therefore conducting produces white light.In this embodiment, when vehicle was travelled by startup to high speed, the light of display board 42 was white from orange, yellow, green, blue, indigo, purple stain in regular turn, that is cool colour is arrived by warm colour.When the speed of a motor vehicle reduces, the variation reversed in order of light, that is by Bai Zhicheng.
Yet in this mandatory declaration is that above-mentioned several colors are an example.In fact, according to the number of each group primary lights, can produce the color of different numbers.The major reason that the present invention that Here it is shows with colorama.Simultaneously, because after color passes to brain via optic nerve, analyze so that the required time of taking action of issuing an order is very short, so can make the driver can take suitable emergency measure quickly.
Refer again to Fig. 1, when brake detector 22 detects the driver and touches on the brake pedal 23, then will brake immediately and detect pulse and send scrambler 34 to, interrupt continuing count content coding, and directly produce preface sign indicating number 111000000, start driver DR counter 33

3, therefore can when brake, flash the redlight as general vehicle.When loosening brake pedal 23, display board 42 can recover to show the light corresponding to the speed of a motor vehicle immediately.
Display unit of the present invention can reach to provide about its vehicle speed to back car with different colours light and change and the purpose of situation, and then plays the effect of collision-proof and guarantee driving safety.
More than illustrate within the present invention with regard to an embodiment and to hold, but ripely obviously can make many different designs according to Spirit Essence of the present invention in the technique person, therefore limit scope of patent protection of the present invention with claims.
