By the following examples, in conjunction with the accompanying drawings the present invention is further described.
Embodiment:
Adopt dutycycle less than 0.2, pulse width is 0.3～2.5ms, and cycle strobe is the stroboscopic pulse light of 20～256HZ.
Interruption and flickering when causing observation for the cycle of glistening because of pulse is extinguished, flash of light must be carried out with the periodic mode that is higher than the human eye vision fusion frequency, this fusion frequency is different according to the size and the light and shade difference of visual field, contain motion scenery when being considered as car light in the visual field, so flash rate is selected between 20～256HZ, its upper limiting frequency is limit by flash of light and photoswitch speed.In actual the use, this frequency must be a normal value of determining.
Utilize photoswitch to make anti-dazzle mirrror retaining side before user, as long as when each car light glistens, photoswitch is held open, and just can not influence observation.Neither need car light to influence illuminating effect when anti-dazzle, can not stop again being influenced observing effect according to the observation of scenery because of special operational.Because of the dazzle most of the time can not see through photoswitch, slackened greatly so finally can enter the dazzle average power of human eye.
According to talbot-pula pottery law: by the equivalent stabilized light source that the high frequency flicker fusion becomes, mean flow rate that its brightness or light intensity equal to glisten or average intensity.Suppose when cycle strobe is 10ms flash of light pulsewidth 1ms,, require the flash pulse power of car light should be for obtaining the average car light power of 60W:
60W/1ms/10ms＝600W
It is unchallenged that such pulse power requires the paired pulses lamp.
Cause in antiglare effect, then be the duty ratio of time that the photoswitch cycle opens, be i.e. the ratio in each opening time and unlatching cycle.When photoswitch that dazzle opened and closed by the cycle, also be cut into the flash pulse in cycle, its equivalent luminance or light intensity also can be by deciding according to talbot-pula pottery law.Because of unlatching and flash synchronization carry out, its dutycycle promptly is approximately the dutycycle of flash pulse, be supposition cycle 10ms, pulsewidth 1ms, dutycycle 0.1, then dazzle intensity in the place ahead will reduce an order of magnitude, as former head-on car light is 60W, behind the anti-dazzle mirrror that constitutes by photoswitch, will be looked as 6W.The visible light flash pulsewidth heals better narrow, but this pulsewidth is limited by the life-span of stroboscopic lamp and peak power, generally between 0.3～2.5ms.Cycle is then longer better, but can not be lower than the human eye vision fusion frequency.
When night during meeting, be the stroboscopic car light as both sides' vehicle, in case both sides' car light duration of light overlaps to some extent, then will cause and dazzle the eyes.To this situation, receive the other side's strobe flash by optical receiver in the device in the present embodiment, and regulate square car light flash of light and the other side synchronously but keep the bigger phase difference that can avoid both sides to glisten and overlap by controller, get 180 ° of maxims usually.Because of each side's photoswitch all is in closed condition when each the other side's car light glistens, so can be than when source of stray light is continuous light, having eliminated dazzle more up hill and dale.In the present embodiment, the stroboscopic frequency control is to be produced by a high stable oscillator, and is a normal value, and the either party's one is subsynchronous among the both sides, just can guarantee can not take place in the long period after this both sides' flash of light that overlaps.Be example still, when frequency stability is 10 with flash period 10ms, flash of light pulsewidth 1ms
-5The time, in case out of control, because of causing flash pulse, the drift of both sides' frequency overlaps, press worst-case computation:
10 * 10
-3/ 2-10
-3/ 2 * 10
-5=200 seconds
Also need 200 seconds time.
Because of the trigger process of flashlight is exceedingly fast, can reach for tens nanoseconds, as long as choose reasonable flashlight discharge loop parameter just can obtain extremely steep light pulse forward position.In addition,,, regulate the time location in this forward position, just finish position or phase modulation light pulse by the form of the coding of information and data so correspondence has the strict leading edge time that accurately repeats because of the car light stroboscopic was undertaken by the aforesaid high stable cycle.Specific practice can be the triggering control signal effect moment or a phase place of utilizing variable delay timer of constant of data coding control or phase shifter to come the change pulse lamp.Because only digital polse form of medium of communication, be easy to from bias light, distinguish, and the pulse power of car light is higher, so the optical communication contact was not limited at night, can carry out in the daytime equally.
Referring to accompanying drawing:
The optical receiver that receives dazzle or optical signal constitutes by optical sensor, amplifier I, analog switch, filter, amplifier II, phase shifter, threshold compataror with door M1.
Optical sensor receives the optical signal on the assigned direction, be transformed into electric signal after, waft and bias light disturbs through bridge-type output offset temperature, be amplified to by the amplifier I to be fit to the level value that cmos analog switch is handled.When the flash of light of square car light, analog switch switches to anti-dazzle mirrror with the signal of amplifier I output, behind the back edge of opening in order to photoswitch wherein and the electric pulse that square car light flash of light produces along aliging.In At All Other Times, signal then is switched to filter and threshold compataror, in order to detect dazzle or communication optical signal.Filter is a high Q narrow bandpass switched filter, and wherein switch controlling signal is produced a crystal oscillation signal frequency split by counting machine, so switching frequency is a crystal frequency stabilization high precision frequency, and this frequency is the frequency multiplication of car light flash rate.So the photoimpact that can produce the stroboscopic car light flash of light that has interference noise that receives is carried out narrow-band filtering.This is in order to guarantee to have eliminated under the electric noise of interference of stray light and car itself and the disturbed condition that mechanical vibration cause the strobe flash electric pulse of output " pure ".Threshold compataror is judged the dazzle whether have certain intensity, and as not, then threshold compataror will export inhibit signal, block with door and will export, and stop the photoswitch cycling, remain opening.Photoelectric pulse signal is exaggerated the device II and amplifies once more, controls but the gain of amplifier II is the photoimpact amplitude that detected by filter, so that when amplifier II incoming level changed, signal still can be amplified to a normal value under not by the situation of peak clipping.As key pulse, transistor T 1(is referring to accompanying drawing 3 for phase shifter equalizer circuit time-delay back output for this value) produce the pulse in the outer strobe flash of reflection forward position through exporting with door M1.

The phase shifter II is to be used for position, flash pulse forward position is regulated and established, and when not making flashing light signalling, the phase shifter II can be cancelled, and energizing signal is straight-through.D type flip flop reaches with door M2, M3 control flash of light is undertaken by lamp L1 and L2 respectively by turns.In single modulated structure, can cancel d type flip flop and one and a door M2.Triggering fiber coupling device that control signal is made of light-emitting diode with the flash of light of door M2, M3 output converts optical signal to and exports through optical fiber.The counting machine I is exported K1～5 with frequency division and is delivered to filter and go master cock conversion.
Stroboscopic car light part receives coupler by stroboscopic lamp L1, L2, tank circuit flash of light binary pair and optical fiber and constitutes.
Because of the stroboscopic lamp flash of light need provide very big immediate current and one ten thousand volts trigging pulse, so these corresponding circuit can only install nearby near stroboscopic lamp L1 and L2, longer apart with control circuit, and driving engine disturbs stronger on the car, so flash of light triggers the Optical Fiber Transmission of control signal, optical fiber receives coupler and adopts photosensor, as photodiode or photo-transistor.Two stroboscopic lamp L1, L2 discharge and recharge the discharge energy-storage loop under the trigger voltage of flash of light binary pair output by turns, send strong flash of light, and here, the stroboscopic pulse lamp can be an xenon lamp, and flash of light effective lighting pulsewidth is 0.8ms.
Anti-dazzle mirrror is made of photoswitch and Drive and Control Circuit thereof.After circuit received the dazzle control signal that demultiplexer sends here, promptly in the output control of decoding gate II, the driven optical switch cycle opened and closed.Open the back along consistent with edge behind the photoimpact that switches the square stroboscopic pulse light of coming by analog switch.Photoswitch adopts three electrode liquid crystal optical gates, and its opening speed can reach 0.03ms, and closing velocity is 0.25ms.
The demodulation code that the two D-latch I of micro controller system acceptance, II are sent here.Micro controller system is equipped with corresponding software, when the information of transmission, finish cataloged procedure, the digital phase shifter II is sent in its coding output, after the count status work " meeting " that the sum counter II is sent here compares, and output time-delay phase shift signal, thereby finish modulation work, the modulator approach here is a quadriphase keying, and modulation can be carried out each pulse, also can the some pulses in every interval carry out.
Supply convertor with the former stand by power source V0 on the car be transformed into working power+V1 that strobe flash parameter regulation requires ,-V2, and the used constant voltage power suspply+V3 of other each several part circuit, ± V4 etc.
In the optical receiver shown in Figure 3, D1, D2 are photodiode, and beam reception the place ahead dazzle another is experienced bias light and diffusion light, and two resistance of series connection with it are used for balance D1 and D2 light sensitive characteristic curve respectively.The effect that is connected on the analog switch on the IC5 output loop is to utilize the signal that glistens at square car light between the off period output to be clamped to zero to lie prostrate.IC6-2 constitute can trigger again monostable, the difference requirement when adapting to the dazzle of stroboscopic formula.Controllable gain amplifier is to be made of IC7 and multiplier IC8.D4, D5 and pull-up resistor constitute and door.
