Constant voltage power suspply 7 is by N 104And C 111Form.N 104Be the mu balanced circuit of three ends, a termination power positive pole, an end are mouth, other end ground connection, C 111Filter capacitor for constant voltage power suspply.Constant voltage power suspply provides a stable operating voltage, makes the controller working stability.
C 109, C 112Be power filtering capacitor.L101 one termination power S101, another termination VD103, VD103 meets S301, and S301 is the positive supply input end, L102 one end ground connection, another termination level negative pole.
Work as S 302When open-circuit condition, one runs into the opposite distant light irradiation, just with dipped beam 2 seconds, 1 second (adjustable) circulation change of distance light, finishes until meeting.Recover country beam immediately.Work as S 302When short-circuit condition, one meet an opposite distant light irradiation after, initiatively dimming recovered also to keep country beam after 2 seconds, became distance light behind the other side's dimming again, just can be again by distance light dimming 2 seconds, if the other side's dimming not then can keep country beam to finish until meeting.
Source switch S 301, when disconnecting S 301Light then can recover manually to become in the place, when connecting S 301After, the fully-automatic conversion light mode of then can choosing any one kind of them becomes light.
Principle of work:
When the power turn-on switch S 301The time, voltage stabilizer N 104Offer the voltage of voltage regulation of each several part 9V, be subjected to the irradiation of the other side's vehicle light when photodiode after, send a signal to amplifier, through V 101, V 102, V 103Three grades of amplifications, offer the working signal of a voltage stabilizing of CPU, but the size of sensitivity can be passed through RP 101Regulate and realize.CPU sends instruction to three NAND gate circuit respectively after obtaining signal.N wherein 101BBe subjected to the control of functional switch, its output feeds back to functional instructions of CPU; N 101AMouth base integrating circuit when connecting, be used for adjusting the length of pulse time, feed back to time signal of CPU; N 103CPU is passed through N 101AAnd N 102A(again through a reverser) delivers to electronic switch V after the instruction coupling computing of sending 104, control relay K 101Closed or disconnect.When illumination is penetrated, R 116End is a high level, when unglazed irradiation, and R 116End is low level.
No matter the other side's vehicle has this controller of arming, perhaps the other side's vehicle can not courtesy be driven a vehicle, and this controller can both be according to the automatic meeting of the wish of oneself.For example: functional switch is at second kind of state, controller on own natural frequency basis, if to can conversion light, also conversion light correspondingly of controller then.The other side is as not conversion light, and then controller is according to time base time (adjustable) the conversion light always of oneself, and meeting is once finishing to recover headlight.That is to say that the time of lampet is the most childlike in 2 seconds (adjustable).
Functional switch is at second kind of state, meets the defeated lamp that initiatively diminishes of the other side's car, becomes headlight after 2 seconds, and at this moment as the constant lampet of the other side, then oneself also constant lampet becomes headlight after the other side diminishes lamp, and just can diminish lamp 2 seconds of back controller recovers headlight again.Perhaps the other side never becomes light, and then controller also keeps headlight always.
If the other side's vehicle is all adorned this controller, or to can courtesy driving a vehicle, promptly vehicle can the automatic safety intersection.
Even this controller breaks down, intersection automatically as long as close the former switch S 301 of power down, can recover manual intersection and become light.The user is without fear of an attack from the rear.
The 12V car is defeated, the 24V vehicle all has suitable model, and the withstand voltage of selective relay is applicable to various types of vehicles.
This controller is easy for installation, does not change other circuit of automobile, and automobile is not had any harmful effect, as usual Switching Power Supply and open lampet in the big greasy weather.
