Description

The intelligent vehicle lamp dimmer

Technical field

The utility model relates to a kind of intelligent vehicle lamp dimmer, particularly relates to a kind of intelligent vehicle lamp dimmer that integrates multiple functions such as automatic bright lamp, automatic beam change, light blast.

Background technology

Known technology such as Chinese patent 97225645,99212112,92220792,88219288,90223789 have all proposed the cars meeting at night automatic device for changing light, by its structural principle as can be known, become only send a car the over there realization light intensity effect under, suppose that two cars have all installed same device for changing light, if the first car has at first become passing light, second car under the light-illuminating that the first car has died down does not just become light so, consequently first car driver is more by strong illumination, causes traffic accident easilier.Want to reach the goal of the invention of above-mentioned patent, necessarily require first and second liang of cars that same device for changing light all is installed.Though and Chinese patent 01223682 has solved the problem of synchronous automatic beam change, but still there is following defective: when first and second liang of cars enter the meeting spacing, the flash of light of first car lasts till that always the other side becomes light or meeting finishes and the dark just end of front light, causes dysopia for the other side's vehicle drivers; Entering road-lamp road-section can not dimming; Light can not be lighted automatically; Light can not blast etc.

Summary of the invention

The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, and a kind of intelligent vehicle lamp dimmer with functions such as automatic bright lamp, automatic beam change, light blasts is provided.

The purpose of this utility model is (solving the technical scheme that its technical matters adopts is) of realizing like this: its circuit structure comprises the photosensitive circuit of forming with bleeder.Far light and near light and flashing signal output circuit, actuating unit and power supply with multi resonant oscillator and NAND gate circuit composition.Photoconductive cell in this photosensitive circuit constitutes the signal input part of bleeder, its two logical transistor switch is connected with frequency divider, its mouth of said voltage comparator is connected with the ground terminal of multi-vibrator, and insert respectively and the input end of door and the CP end of frequency divider, the mouth of this frequency divider be connected with another input end of door, the mouth of multi-vibrator and not gate is connected with the signal input part of actuating unit by amplifier respectively.

For realizing that two cars become light synchronously, the utility model has been taked the interrogation reply system of writing to each other.The beneficial effects of the utility model are, light light automatically, and the flash of light prompt facility can cause the other side's attentions of sending a car, and increases one's own side's safety, automatic beam change synchronously, and do not require that the meeting both sides install this controller simultaneously, do not influence the hand switch use.Two cars always have a car and at first enter readiness, i.e. flash state in the process that moves closer to, this flash state is exactly a kind of signal communication inquiry message, and the timely change light that the other side sends a car is exactly one to answer accurately, has finished question and answer thus and has become the light path preface synchronously.

The utility model compared with prior art, be characterized in " whom who installs is benefited ", and be not to necessarily require first and second liang of cars that this controller all is installed, if the first car has been installed this controller, and the second car is not installed this controller, will be setpoint distance (being generally about 150 meters), the first car begins flash of light to the signal of second car, if the automobile-used manual type of second this moment becomes light, the first car can become passing light automatically, if the constant light of second car, the first car can recover country beam after 4 seconds of glistening.After having overcome the first car and becoming dipped beam, if the constant light of second car makes the first car more be subjected to the drawback of second car strong illumination on the contrary.The flash of light of first car can cause second car driver's attention, all can be favourable no matter the second car becomes constant light to first car driver, the device for changing light of this " who install who be benefited " has overcome prior art, and to become light asynchronous or require first, second two cars that the defective that could realize automatic beam change must be installed simultaneously.Street lamp lock-in circuit of the present utility model has overcome automobile and has sailed the drawback that the city street lamp highway section still uses country beam to travel into.

The specific embodiment

Below sketch the principle of work of the utility model embodiment

Open ignition lock, connect controller power source, control promptly enters mode of operation, and daytime, photoconductive cell RG1 resistance was very little, and 3 pin of 1C1 be " 0 ", not triggering and ending of KG, and three relay J D1, JD2, JD3 can not adhesives, and lamp does not all work.To evening, the RG1 resistance increases, and 1C1 3 pin that overturn become " 1 ", trigger the KG conducting, and 3 pin are held by the CP that R7 has also triggered CD4017 by the positive rise of " 0 " changes " 1 " simultaneously, makes 4017 3 pin become " 0 ".

The RG1 base stage is through D4 ground connection, and BG1 ends, the BG2 conducting, and the JD1 adhesive, passing light is bright.Because the KG conducting, JD3 is adhesive also, and the instrument panel lamp rear taillight is also lighted simultaneously, when it was darker, the RG1 resistance further increased, and the RG3 base current reduces gradually, when arriving to a certain degree, BG3 ends finally, and the 15 pin current potentials of CD4017 raise, 4017 reset, and 3 pin become " 1 " by " 0 ", the BG1 conducting, BG2 ends, the BG4 conducting, and JD1 disconnects, the JD2 adhesive, passing light goes out, and country beam is bright.

When send a car in the place ahead, along with moving closer to of two cars, the RG1 resistance is more and more littler, when two cars are about 150 meters apart, the 1C1 upset, 3 pin are output as " 0 ", and the 1C21 pin is by 1C13 pin ground connection, the 1C2 starting of oscillation, country beam, passing light are alternately glittering, send a car to the other side and send cue.This moment, if because brightness reduces, the RG1 resistance raise the other side's dimming of sending a car, and 1C1 3 pin that overturn become " 1 ", the 1C2 failure of oscillation, and the CD40173 pin becomes " 0 ", and the BG1 base stage is by short circuit, and BG1 ends, the BG2 conducting, the JD1 adhesive, passing light is bright, and two cars are all used the passing light meeting.Because the BG1 resistance increases, CD4017 resets, and changes into country beam behind the meeting.

The constant light if the other side sends a car, after the 1C1 starting of oscillation, 4 pin voltages by 4 seconds kinds of R15 discharge after, 4 pin voltages are reduced to below the 0.4V, the 1C2 failure of oscillation, and this moment, BG1 still was in off condition, it should be bright passing light, but because BG24 pin voltage is reduced to 0.4V BG5 and just ended, the 1C43 pin becomes " 0 ", and the BG2 base stage is by diode D12 ground connection, BG2 also ends, so the BG4 conducting, the JD2 adhesive reverts to country beam again.

When entering the highway section of street lamp, because the RG2 resistance reduces, 1C5 3 pin that overturn become " 0 ", and 1C4 3 pin are output as " 1 ", have removed the ground state of BG2 base stage, and JD1 again can adhesive, so country beam becomes passing light.

The effect of BG6.In order to guarantee that becoming electrical distance is 150 meters, the resistance of RG1 is very big during the 1C1 upset, so just make automatic lighting time very late, drivers are not quite satisfied, in order to make drivers arranged the automatic lighting time of a door instrument, guarantee to become electrical distance again, designed the bright lamp of being made up of R19, BG6 and shifted to an earlier date circuit, when daytime, three relays did not all have adhesive, 2 of a of BG6, b were conductings, so just make R3, R4 directly receive on the 2nd pin of 1C1, make lighting time in advance.Behind the bright lamp, BG6 ends, and 2 disconnections of a, b recover primary circuit.
