1., front truck turns to and informs rear car: τ 4 front truck left steering; τ 6 front truck right steering; During τ 7 front truck normally travels;
2., τ 3: front truck is in meeting (front truck receives τ 2), launches and be automatically converted to transmitting τ 3 from normal transmission τ 7 after front truck.
Front reception: 1., meeting: two cars meet meeting, and before both sides, receptor receives the front transmitting τ 2 that the other side sends a car, each this car of self-starting meeting program, and change country beam is passing light;
2., rear car trails: the positive meeting of front truck, left steering, right steering, and the τ 3, the τ 4 that launch after the front receptor of rear car receives front truck, τ 6 all travel by the mode of trailing, and send the sound and light signal (referring to Figure 24) of the corresponding motoring condition of front truck;

Situation before meeting, automatic control device is in normal traveling (not receiving outside infrared signal R=1): front reception dutycycle discriminator circuit mouth is high level R=1, no matter C=0 or C=1, when alternately occurring, for or the receiving key circuit 12a mouth of door all have: A=R+C=1+0 (1)=1, subsequent conditioning circuit does not start; Receiving key circuit 12a output terminals A=1 also feeds back to transmitting-receiving control circuit 16a Exclusive-OR gate (XOR gate) input one, and another input two of Exclusive-OR gate (XOR gate) controls by the transmitting-receiving periodic Control frequency f 2 of oscillating circuit 15a:
B=0, A=1 when transmitting-receiving periodic Control frequency f 2 is negative half period, there is C=A+B=1+0=1 (Exclusive-OR gate (XOR gate) two scale notation summation operation), launch modulation circuit three value and gate before C=1 makes and be in opening state, front transmission circuit is in the transmitting cycle, and automatic control device is in emission state; At this moment no matter whether front acceptor circuit receives outside infrared signal (R is any value), C=1 locking or door receiving key circuit, namely when automatic control device itself is launched, locking receives, and the return signal receiving its own transmission infrared signal chance barrier also can be avoided to cause automatic control device malfunction simultaneously;
The B=1 when transmitting-receiving periodic Control frequency f 2 is positive half cycle, normal operation R=1, A=1, transmitting-receiving control circuit has C=A+B=1+1=0 (Exclusive-OR gate (XOR gate) two scale notation summation operation), launch modulation circuit three value and gate before C=0 makes and be in blocking, stop launching, automatic control device is in receiving condition, and when automatic control device itself receives, locking is launched.Therefore, self-propelled vehicle travels separately its own transmission and receive also can alternate run;
The above process R=1, no matter B=1 or 0 all has A=1, and output relay does not start, country beam Chang Liang.
Before automatic control device, receptor receives outside infrared signal R=0:
During meeting, this car and the other side send a car and meet, Ruo Benche infrared receiving terminal takes the lead in receiving offside infrared signal τ=τ 2, front reception dutycycle discriminator circuit exports R=0, when receiving key circuit is also in receiving cycle C=0 this moment simultaneously, (being in the receiving condition receiving and dispatching single labour movement row) receiving key circuit output end A=R+C=0+0=0A=0 controls following circuit respectively: R=0, voltage identificating circuit 20a exports R low level, transmitting-receiving control circuit output terminals A is low level, start-up study reset circuit exports high level (s13-3) and time delay 0.5-1.0 resets (preventing critical conditions instability) second, output relay action, normal opened contact closes, and it is passing light Chang Liang (automatic beam change process) that this car becomes country beam, the return-to-zero of A=0 oscillating circuit failure of oscillation, all frequencies reset B=0, and (vibration reset terminal is that low level resets, namely circuit stops oscillation), C=A+B=0+0=0C=0, transmitting-receiving control circuit exports as low level, receiving cycle for this car starts to launch with offside cycle synchronisation (Ben Che and the synchronous point of penetration of opponent vehicle are just in time not the starting points that offside launches the cycle).From this moment, length only (the Yin Benche oscillating circuit failure of oscillation synchronous with the transmitting cycle ' beginning ' of the other side's meeting operatorless device of this car receiving cycle, have nothing to do with this car oscillating circuit), until opponent vehicle launches end cycle, (A=1 is recovered) till this car does not receive infrared signal, the starting of oscillation again of this car oscillating circuit, before the one-period of all frequency divisions, half cycle is low level, transmitting-receiving periodic Control frequency f 2 is still in B=0, this car of C=A+B=1+0=1C=1 transmitting cycle starts, opponent vehicle receiving cycle starts to launch cycle synchronisation with this side, the reiving/transmitting state of both sides' automatic control device in Vehicle during Crossing Event is contrary, both sides are in transmitting-receiving and replace in mutual synchronized operation.
This car launch the cycle start while start before launch (time-delay reset circuit action the time delay of infrared power intensifier circuit in modulation circuit, starting power intensifier circuit), add the infrared emission power of university degree car, expand this car transmitting range, before forcing opponent vehicle, receptor enters active region, and the other side's automatic control device immediately synchronism switching country beam is passing light Chang Liang.Be less than the half 0-5ms of f2 (100Hz) one-period during this period of time; Because this car automatic control device might not launch the infrared signal just in time receiving the other side's transmitting at the very start in cycle at opponent vehicle, therefore both sides' automatic control device successive relay trip time is all less than 5ms, the speed of response 20ms of human eye, so can think that both sides' country beam of meeting is synchronous dimming lamp.
After opponent vehicle meeting automatic control device receives the infrared signal synchronous action of this car enhancing, offside also can increase offside self infrared emission power while being in the transmitting cycle subsequently, forces that side of the first action of the meeting automatic control device that meets also can receive the infrared signal of enhancing; By infrared light path and the respective corresponding circuit of both sides, define closed loop positive feedback effect between both sides' automatic control device, overcome two cars in the fugitiveness of critical conditions automatic control device action of meeting; In Vehicle during Crossing Event, the receiving cycle of the automatic control device of both sides is synchronized with the transmitting cycle of opponent vehicle in succession simultaneously, the emission state between two car automatic control devices and receiving condition is made all to be in interactive synchronized operation, overcoming meeting both sides to meet between process automatic control device because receiving sensitivity or transmitting range there are differences, and avoids and may switch asynchronous and disadvantage that is that bring dazzle dazzling because self-propelled vehicle both sides country beam.After two cars cross, before both sides, receptor does not all receive square signal, and two car automatic control devices reset and in succession recover country beam Chang Liang.
Above-mentioned meeting automatic control device, achieves meeting both sides real-time synchronization and automatically becomes country beam into passing light, both avoided dazzling, also can reduce driver's manual labor intensity, overcome nervous degree during meeting, especially to new hand for driving a car, and favourable meeting traffic safety; Because when described automatic control device is launched, locking receives, the disadvantage receiving self infrared chance barrier return signal generation malfunction can be avoided again.

See right steering lamp control circuit in Figure 21, be made up of not gate 50-4, diode D2, D3, resistance R5 and sail back former track country beam automatic restoring circuit: not gate 50-4 is serially connected between two backward diode D2, D3 and forms loop, is connected between s40-1 and controllable silicon SCR charging capacitor C1 positive pole; Figure 24 [there is car at rear] signal s2-20b is connected through resistance R5 NAND gate 50-4 input end.Before overtaking other vehicles, receive dutycycle τ 7, overtaking steering lamp start-up circuit s40-1 is low level, and 50-4 exports high level, is isolated by backward diode D2, on charging capacitor C1 without impact; If the tailstock now for overtaking other vehicles has pursuit-type vehicle again, after receive τ 2 and have s2-20b to be high level, connect through resistance R5, diode D3 and s40-1, s40-1 has been low level, and it is constant that not gate 50-4 exports high level.Overtake other vehicles after crossing, receive no signal before overtaking other vehicles, s40-1 is high level; Overtake other vehicles and sail go back to former track, after receive the τ 2 launched before passed vehicle and have s2-20b to be high level, s40-1 is again high level, diode D3 two ends are high level, not gate 50-4 output low level, SCR charging capacitor C1 is instantaneous discharges electric residue, and silicon control blocks, extinguish right steering lamp, automatically recover country beam Chang Liang; Do not trail car for the rear of overtaking other vehicles, situation is the same.
Long-and-short distant light steering indicating light automatic control process of overtaking other vehicles illustrates:
Before overtaking other vehicles, pursuit-type vehicle at a distance of front truck 150 meters with far, τ 7 infrared signal that front receptor is launched after receiving front truck is not in infrared pickoff active region, the τ 7 received is intermittent imperfect infrared sequence impulse singla, be 0 < τ < τ 7 average voltage through dutycycle voltage transitions, until the meeting automatic control device action s13-3 receiving τ 2≤τ < τ 7 rear car is high level, output relay starts:
1., closed to become country beam be passing light to normal opened contact, and during this, rear car is by following at a distance, though meet automatic beam change condition, now not and the front truck meeting travelled in the same way.Meet the regulation of ' closely travel rear car and country beam must not be used '.
2., normal opened contact closes s14-2 high level, in Figure 19 time delay break switch circuit analog switch 30-3 close, but now have τ < τ 7, single comparator voltage identification 30-6 exports s13-4 to be continued to maintain high level, and it is constant that relay maintains operating state always.
Rear car is to surmount front truck close to front truck object, when two cars continue close to about about 150 meters, the infrared pulse signal that τ=τ 7 that before rear car, receptor is launched after receiving front truck is complete, Figure 19 is that in Duty ratio control flash of light start-up circuit, single comparator voltage identificating circuit 30-6 exports s13-4 low level; Meeting automatic control device output relay change-over contack start repeatedly to switch during this period of time in, because Figure 20 is that time delay circuit 1,2 of sampling in overtaking steering lamp start-up circuit exports high level and time delay simultaneously, its NAND gate 40-1 is made to export the steady low level of s40-1; Not gate 40-2 exports s40-2 pulsation-free high level, controls respectively:
1., s40-2 pulsation-free high level, left steering lamp power circuit control end is high level, and left steering lamp starts also glittering;
2., s40-2 pulsation-free high level, through isolation diode D1 resistance R3 moment right-hand turning be full of electricity to lamp control circuit charging capacitor C1, make it have enough discharge times; Controllable silicon SCR is blocking state, prepares for opening right steering lamp;
3., the steady low level of s40-1, be trail electric capacity 60-5 in delay startup circuit to discharge through Figure 22, ' timing of overtaking other vehicles ' start.
In overtaking process, meeting automatic control device output relay change-over contack switches repeatedly, and for high level provides steering indicating light flashing power source after output relay normally closed contact s14-1 is closed, s40-2 high level lights left steering lamp 50-01; The normally closed normal opened contact of output relay disconnects and closing again, and conversion uses long-and-short distant light.This overtaking process meets the regulation of traffic safety law implementing regulations the 47 article about ' during overtaking, should open left steering lamp in advance, conversion uses high-low beam light '.
Said process continues up to front and back two motor vehicles and crosses, at this moment the driver that overtakes other vehicles has started left steering and has left the continuation of former track from front truck left overtaking, the infrared signal of launching after the front receptor of overtaking other vehicles does not receive front truck, after output relay normal opened contact s14-2 returns, Figure 20 samples time delay circuit 2 output low level, NAND gate 40-1 exports s40-1 and sports high level, and s40-2 becomes low level:
1., s40-2 becomes low level, left steering lamp power circuit control end dead electricity, the extinguishing of left steering lamp;
2., s40-1 sports high level and triggers the control pole k of controllable silicon SCR through electric capacity C2, and controlled silicon conducting discharging resistance R4 be high level, and through two not gate 50-3,50-2 output s50-1 high level, 50-02 is glittering for unlatching right steering lamp; Charging capacitor C1 starts electric discharge, and ' sailing back the timing of former track ' starts; Lose infrared signal because two cars cross for overtaking other vehicles, after right steering lamp is lighted, s50-1, through the isolation diode 30-2 of Figure 19 Duty ratio control flash of light start-up circuit, continues the work maintaining flash of light start-up circuit, exports s13-4 low level; Now Figure 13 s11-2a no signal, exports s50-2 by Figure 21 not gate 50-3 and maintains time-delay reset circuit trigger end low level in Figure 18, and output relay continues to maintain and switches, and continues to open right steering lamp, conversion uses high-low beam light.
Continue to overtake other vehicles after crossing for overtaking other vehicles and start to surmount front truck, after sailing go back to former track, after receive the τ 2 launched before passed vehicle and have s2-20b to be high level, sail back former track automatic restoring circuit not gate 50-4 output low level, charging capacitor C1 forced electric discharge is ended, silicon control recovers to block, ' sailing back the timing of former track ' terminates, s50-1 becomes low level, right steering lamp power circuit control end dead electricity, and right steering lamp extinguishes; S50-2 becomes high level, and Figure 18 time-delay reset circuit trigger end recovers high level, and time-delay reset circuit resets, and output relay dead electricity normally closed contact returns, and recovers country beam Chang Liang, completes overall process of overtaking other vehicles.
The above meets law on road traffic safety implementing regulations the 47 article about ' rear car should after confirming there is sufficient safety distance, from front truck left overtaking, after pulling open necessary safety distance with passed vehicle, open right steering lamp, sail go back to former track ' regulation.
Trail passing light control circuit 60:
Figure 22 trails passing light control circuit.
Trail for overtaking other vehicles because certain reason can not continue to overtake other vehicles, in order to avoid long-and-short distant light and left steering lamp glimmer for a long time, to the adverse effect for front and back driving vehicle driver vision of overtaking other vehicles, automatically can enter following at a distance when exceeding about half a minute during this period of time for overtaking other vehicles.See Figure 22, described in trail passing light control circuit by trailing delay startup circuit and trailing control circuit and form, between association link.
Trail delay startup circuit: trail delay startup circuit input end and be connected with Figure 20 overtaking steering lamp start-up circuit mouth s40-1, the integrating circuit be made up of with electric capacity 60-5 resistance 60-4 is connected with not gate 60-2 and exports, charging diode 60-3 is in parallel with resistance 60-4, forms to fill soon to put time delay circuit slowly.
Trail control circuit: trail control circuit and be made up of bistable trigger 60-1, the mouth of not gate 60-2 forms through electric capacity 60-9 and grounding resistance 60-10 the trigger end 1C that differential circuit is connected to bistable trigger 60-1, bistable trigger mouth 1Q (s14-5) and Figure 18 meeting automatic control device output relay or door s14-5 be connected; Direct clear terminal 1R is connected with positive supply through resistance 60-7 respectively, and being connected to Figure 24 through electric capacity 60-6 is [there is car in front] sound and light signal s60-1 in signal control display circuit block diagram.
In Figure 22, B10 is overtake other vehicles recovery button and 60-11 control angle sensor parallel, accesses between positive supply and trigger end 1C simultaneously, trailing, restarting the program of overtaking other vehicles for stopping rear car manually or automatically.
Overtake other vehicles and enter the explanation of following at a distance passing light control process:
The rear car s40-1 that starts to overtake other vehicles is low level, and from this moment, the electric capacity 60-5 being full of electric charge starts through the slow back discharge of resistance 60-4, trails delay startup circuit and starts ' timing of overtaking other vehicles '; When capacitance voltage slowly declines, setting time delay exceedes the designated time (about half a minute), not gate 60-2 input voltage reaches low level turnover voltage, export high level, on resistance 60-10, produce first positive pulse through differential capacitance 60-9, through trigger end 1C, bistable trigger 60-1 is overturn, mouth 1Qs14 – 5 becomes high level, ' timing of overtaking other vehicles ' terminates, and stops overtaking other vehicles; S14 – 5, through the output relay of meeting automatic control device 100 or gate diode 14-4, makes output relay be in pressure operating state always, and contact stops switching, and normal opened contact closes passing light Chang Liang, automatically enters following at a distance:
1., because output relay change-over contack stops switching back and forth, Figure 20 is that overtaking steering lamp start-up circuit not gate 40-2 exports s40-2 low level, left steering power circuit control end dead electricity, and left steering lamp extinguishes;
2., relay normally closed contact disconnect s14-1 be low level, steering indicating light loses flashing power source, left steering lamp dead electricity stop dodge; Relay normally open contact closes passing light Chang Liang, stops overtaking process, automatically travels by the mode of trailing.
Meet the traffic safety law implementing regulations regulation that ' when the rear car of equidirectional traveling and front truck closely travel when trailing, country beam must not be used '.This automatically enter the mode of trailing also meet urban highway traffic crowded time, the motoring condition of the power actuated vehicle mutually trailed.
At this moment overtaking steering lamp start-up circuit NAND gate 40-1 exports s40-1 high level, and the conducting of right steering lamp control circuit silicon control possibility, at this moment because meeting output relay normally closed contact disconnects s14-1 low level, right steering flick of lamp power loss, can not malfunction.
In the process of trailing, current vehicle has sailed out of former track (comprise sailing far or turning to and leave away), this car self-propelled vehicle meets [there is car in front] s60-1 signal terminating (illustrating see in Figure 24) of signal control display circuit, direct clear terminal 1R produces negative going pulse, make bistable trigger 60-1 return-to-zero, mouth 1Qs14 – 5 becomes low level, simultaneously do not receive infrared signal for receptor before overtaking other vehicles, output relay normally closed contact closes, country beam recovers Chang Liang automatically, and self-propelled vehicle enters normal motoring condition automatically.
Enter when overtaking other vehicles in the process of trailing, driver has found that there is chance of overtaking other vehicles, utilize the bearing circle left-handed turning that angular transducer 60-11 is housed to when getting to certain angle, make trigger end 1C access positive supply and produce second positive pulse, recovering bistable trigger 60-1 mouth 1Q is low level, stop following at a distance, reenter motoring condition of overtaking other vehicles; Or manually click [recovery overtake other vehicles button B10] that control panel is arranged, make trigger end 1C access positive supply and also can produce second positive pulse, recovering bistable trigger 60-1 mouth 1Q is low level, before trailing rear car, reception launches τ 7 after still receiving front truck, also can restart the program of overtaking other vehicles.
The above self-propelled vehicle meet meeting, overtake other vehicles, car light that the driving process such as to trail all omnidistance can realize automation, instead of legal self-propelled vehicle in [law on road traffic safety] and to meet whole M/Cs of process; At this moment driver merely can hold bearing circle by both hands, without the need to considering other operations of hand, both reduced labor intensity, nervous degree can be overcome again, also can reduce people for malfunction erroneous judgement, especially favourable Getting Started, effectively stops serious accident generations such as bumping against or knock into the back, improve road rate, produce obvious social benefits.
Figure 23 is dense fog button connection diagram: utilize the transmitance of infrared light in dense fog or haze to be greater than the characteristic of visible ray, by pressing band mechanical latching or self-sustaining [dense fog button] B20, can make before and after this car automatic control device, to launch the maxim of the infrared emission power increase in modulation circuit to design, further expand before and after the transmitting range of infrared light, advance notice is in advance met the sound and light signal of motoring condition between vehicle as far as possible.This is at night, especially the inclement weather that the visbility such as dense fog wind and snow haze is extremely low, motor vehicle energy is made to understand mutually the motoring condition of front and back adjacent vehicle, again by of short duration voice message sound, can driver be reminded in time to take care, to running into driver's insobriety, as drunk, the situation such as morning is tired, absent-minded, serious accident occurs effectively to prevent that collision from knocking into the back etc.
The self-propelled vehicle signal control read out instrument 400 that meets is made up of signal control device and Signal aspects control panel.

1., ' two car meetings time ' both sides show [this car meeting A3] (τ 2) simultaneously, to be turned to inform that rear car ' object selected control circuit ' is connected by s2-20 with this car in this car Figure 14, launch dutycycle after when making this car meeting and automatically become τ 3 from τ 7; Receive dutycycle τ 3 for receptor before overtaking other vehicles, in rear car Figure 24, send [the positive meeting A9 of front truck] connect s2-30; Simultaneously making rear car Figure 18 force output relay for overtaking other vehicles from being repeatedly switched to a direct acting through s2-30, stopping overtaking other vehicles, making rear car enter following at a distance state;
2., front truck left steering time launch thereafter dutycycle τ 4, the front receptor of rear car receives dutycycle τ 4, through for while sending [front truck left steering A7] (τ 4) in the Figure 24 that overtakes other vehicles, makes to enter following at a distance state for overtaking other vehicles equally through s2-30.
Clear in order to describe, to meet between each circuit of signal control circuit by the description of isolation diode (all drawing in figure) associated connection described in all omitting, refer to Figure 24, as follows.
Before meeting automatic control device, receptor receives 0 < τ < τ 7 by near process, there will be τ 2 ... τ 6 average voltage moment; In order to prevent sounding optical signal by mistake, utilize time delay one second, just acoustic-optic indicator can be sent after signal stabilization.
2), rear receiving demodulation change-over circuit 11b, receive dutycycle τ 2, τ 7 and convert respective settings magnitude of voltage to and export (s11-2b), one once voltage identificating circuit 2-20b, 2-70b respectively, compared with the predeterminated voltage that the dutycycle τ 2 formed with each dividing point, τ 7 are corresponding, and equal signal gating is exported, through corresponding signal control circuit, showing [back car A5] τ 2 with ' front truck of pursuit-type vehicle ' in signal display circuit respectively, after ' two car meetings cross ' to show [meeting leave away A4] τ 7 corresponding for both sides;

Drive with caution! B01 (B02)].
In Figure 24, the connection of voice message signal and corresponding lamp display is all omitted, and does not get rid of and utilizes other wireless modes to be associated therebetween, as radio, bluetooth, ultrasonic, Infrared Transmission voice signal etc.
Before and after in Figure 24, relative distance display circuit principle describes in detail.
Relative distance shows: comprise [display of front truck relative distance] A01, [display of rear car relative distance] A02.Distance display circuit is made up of level indicator (utilizing display volume indicator module as AN6884) and multiple (5,7,9,12) luminotron, two spacings nearlyer level indicator outgoing level is higher, the number that luminotron is lighted is more, the number that luminotron is lighted and relative distance are inversely proportional to, and realize the display of relative distance analog signal.
Relative distance light display principle: send a car before and after this car, with this car at a distance of 150 meters with far, the infrared signal received is not in regulation range of receiving, the dutycycle 0 < τ 2 that the front and back that before and after this car, the Receiver of receptor sends a car (meeting, turn to, trail, overtake other vehicles) before and after receiving are launched ... < τ 7, be intermittent imperfect infrared pulse sequence, so dutycycle voltage transitions becomes average voltage very little.
See that Figure 24 first sets, receiving demodulation change-over circuit 11a, 11b export s11-2a, s11-2b without voltage identificating circuit in front and back, directly be connected with [front truck relative distance shows A01], [rear car relative distance A02] of the signal display circuit that meets respectively, see choice refreshments dotted line in figure.Just start [display of front and back relative distance] and 1-2 luminotron or unstable glittering can only be lighted, start intermittently to send [to send a car! Drive with caution! ] of short duration voice message.When dutycycle voltage transitions not yet reach τ 2 ... the corresponding average voltage level of τ 7, [this car meeting A3] ... before [back car A5] or [there is car A6 in front] signal is not lighted, when visbility is lower, although do not know the concrete distance of sending a car, but always know that front or rear have car to arrive, interval sends voice message, can driver be reminded as early as possible to drive with caution; Especially before dawn driver tired or drunk when, this prompting is very important.
Send a car after current and continue close to this car in 150 meters, the infrared signal of complete (saturated) can be received, light luminotron number only corresponding with the dutycycle received, send [this car meeting A3] or the acoustic-optic indicator such as [back car A5], [there is car A6 in front], also send corresponding of short duration voice message simultaneously, can confirm that fore-aft vehicle closes on, this car should be tried one's best and be dodged to the right, and alerting drivers need drive with caution.
Because receiving saturated infrared signal in this section of distance, the luminotron quantity lighted is corresponding with dutycycle, and the relative distance of sending a car with front and back has nothing to do; On the contrary, when rear car is in this segment distance trailing front truck, for the different motoring condition of front truck (front truck normally travels, meeting, turn to), even in same distance, rear car receives the luminotron that different duty lights varying number, instead rear car driver thinks it is that relative distance distance from front truck is different by mistake, causes erroneous judgement.
For sending a car before and after realizing in predetermined distance 150 meters by as far as closely, and relative distance simulative display from the near to the remote after crossing, namely the simulative display that the luminotron quantity lighted in relative distance Circuit display and relative distance are inversely proportional to, is explained in conjunction with Figure 24, Figure 25:
1., meeting overtakes other vehicles and trails, two cars by as far as closely close to each other, relative distance simulative display:
See that Figure 24 is signal control display circuit block diagram.Signal control of meeting in figure read out instrument also comprises front truck relative distance circuit 31a and rear car relative distance circuit 31b.
Front truck relative distance circuit 31a signal is introduced by Receiver 7a--s11-1a in receiving demodulation change-over circuit 11a before peripheral Figure 13, forms through monostable circuit 9a ' (as time base circuit 555 forms), dutycycle voltage conversion circuit 8 ', integrating circuit rc (integrating resistor r is in parallel with backward diode d) and [front truck relative distance shows] A01 and is linked in sequence.
When this car Receiver receives complete infrared pulse signal, utilize and export the monostable circuit 9a ' that positive pulse positive rise triggers band constant time lag, no matter any dutycycle in τ≤τ 7, all exports the positive broad pulse of band constant time lag.Assuming that constant time lag (pulsewidth) 0.7ms (as 1kHz dutycycle τ 7), at this moment Ben Che with send a car the process of meeting (comprise meeting, overtake other vehicles, trail) there will be different duty τ 2 ... τ 7, all convert fixed pulse width to by maximum duty cycle τ 7 through monostable circuit time delay, the average voltage converted to is a fixed value; Send a car close in 150 meters, through integrating circuit rc process of charging, the voltage be added in relative distance display slowly rises, and the luminotron quantity lighted increases gradually, and indirect analog display is sent a car and gradually approached this car.When the speed of a motor vehicle is that 100km/h two car meets and needs 2-3s, the time constant of rc is set about 2.5s.Ending during this period of time, lighting [front truck relative distance display A01] all luminotrons.Meet self-propelled vehicle and meet process by as far as near relative distance simulative display.
Two cars cross, and cannot receive square signal, and integrating capacitor electric charge is through the rapid back discharge of diode, and [front truck relative distance display A01] extinguishes.
Rear car relative distance circuit 31b signal is introduced by Receiver 7b--s11-1b in receiving demodulation change-over circuit 11b before peripheral Figure 14, and structural principle is identical with front truck relative distance circuit 31a.
2., after meeting overtakes other vehicles and cross, two cars are left away from the near to the remote mutually, relative distance simulative display:
The above address only vehicles meeting, overtake other vehicles, trail and be inversely proportional to by the luminotron quantity lighted as far as near procedure and relative distance.After crossing for meeting, two cars are opposing leaves away, and both sides, by front relative distance Circuit display, become rear relative distance Circuit display; For to overtake other vehicles and the parking stall, front and back of passed vehicle is exchanged after crossing for overtaking other vehicles, passed vehicle, by rear relative distance Circuit display, becomes front relative distance Circuit display, then contrary for overtaking other vehicles.After above two kinds of situations are met cross to two cars, front and back relative distance Circuit display all exchanges.Sail go back to former track owing to overtaking other vehicles after crossing, two cars that meet close on and receive saturated infrared signal, and at this moment the front relative distance circuit of passed vehicle or the rear relative distance circuit of overtaking other vehicles should export maximum level, and the light-emitting diode of two car relative distances displays should all be lighted.Obviously between above-mentioned two cars by the relative distance circuit that closely meets through integrating circuit, directly can not meet now relative distance simulative display from the near to the remote between two cars.
Relative distance simulative display from the near to the remote after two cars cross, see Figure 25 be meet cross after relative distance display interchange circuit device (being introduced by Figure 24 part), relative distance circuit 31a, 31b integrating resistor before or after introducing from periphery, is made up of start-up circuit 32a, 32b of display exchange comparator F, the analog switch M0-3 of correspondence.
Self-propelled vehicle meet cross time, formerly receive receptor loss signal before or after two cars of infrared signal, its integrating capacitor c oppositely discharges soon from maximum level, integrating resistor r produces counter-current, utilize the comparator on this integrating resistor of access to export and start analog switch M1-3, its contact switches interlock circuit in the opposite side phase relative distance circuit after exchange, completes relative distance simulative display for the opposite side after exchanging from the near to the remote after satisfied crossing.
Relative distance display interchange circuit principle after self-propelled vehicle meets and crosses: for overtaking process, switch to front relative distance circuit 31a to be specifically described with relative distance circuit 31b interlock circuit after passed vehicle with after crossing, when other two cars meet, situation is identical.
Relative distance display interchange circuit has, and the start-up circuit 32b of passed vehicle is connected with analog switch M (1-3) control end by exporting by the comparator F that polarity is connected with integrating resistor r two ends in the rear flank relative distance circuit 31b before crossing; The commutation circuit (31a ') of passed vehicle is by analog switch contact M1-3 in analog switch M, switchings formation is carried out to interlock circuit in opposite side (front) relative distance circuit (31a) after crossing: M1 make 555 reset terminals 4. ground connection (reset) make its output low level, for locking monostable circuit; Power supply is connected with integrating capacitor c through M2, electric capacity c1, for being full of electric charge to integrating capacitor c is instantaneous after analog switch action; M3 is connected with the integrating capacitor c of (front) relative distance circuit (31a) from the positive input terminal of comparator F through discharging resistance r1, and the comparator making the high level of electric capacity c maintain start-up circuit continues to export high level; Setting r1c time constant longer be 5-6s, because of this section two car overtake other vehicles departure proess comparatively meeting to grow close to process.The integrating capacitor c voltage of this discharge process declines gradually, and the light-emitting diode quantity that (front) relative distance circuit (31a) is lighted and two workshop relative distances are inversely proportional to.Until two cars discharges end of a period away from, integrating capacitor c mutually, make comparator reset (output low level), whole relative distance procedure for displaying terminates.
In order to clear brief description, do not draw in foregoing circuit to isolate the isolation diode switching front and back level and should add.
Overtaking other vehicles before not close to passed vehicle, is by following at a distance, and quick in the same way by as far as closely catching up with people having a common goal; This and overtake other vehicles cross after sail go back to former track, people having a common goal leaves away in the same way fast from the near to the remote, and these the two kinds running times of situation in 150 meters that meet are identical 5-6s, and the time 2.5s of both meetings in 150 meters wants slowly a lot.Utilize same circuit to complete above-mentioned two kinds of periods, be described below:
See Figure 25, in front and back, relative distance circuit 31a--31b exchanges into commutation circuit 31a '--and in the integrating resistor r1 of 31b ', series resistance ro is in parallel with the analog switch Mo contact of setting; Analog switch Mo is controlled by Figure 24 Signal aspects [this car meeting A3] s2-20.The only analog switch Mo action when meeting, short circuit series resistance ro presents minimum resistance, obtains the shortest time.Other motoring conditions, analog switch Mo is failure to actuate, and obtains the long period.Such relative distance simulative display that can meet different motoring condition.
Describe more than comprehensive, the relative distance breadboardin display brief description after self-propelled vehicle being crossed in conjunction with Figure 24 and Figure 25:
1., overtake other vehicles cross after sail go back to former track, wherein the rear relative distance circuit 31b of passed vehicle exchanges into front relative distance circuit 31a: the analog switch contact of action in the rear start-up circuit 32b that the integrating resistor in the rear relative distance circuit 31b of passed vehicle is connected, to exchange after before relative distance circuit 31a interlock circuit switch, form commutation circuit 31a ' → 32b--31a--31a ', wherein relative distance display A01 complete and cross after relative distance simulative display from the near to the remote.
After sailing go back to former track when overtaking other vehicles, the rear of passed vehicle still has pursuit-type vehicle, rear relative distance circuit 31b integrating resistor is in positive potential, comparator output low level, analog switch resets, cause the integrating capacitor c of the front relative distance circuit (31a ' gain 31a) of passed vehicle to be in high level, recover normally to show, light a greater number light-emitting diode.Other motoring conditions are similar.
2., in like manner, overtake other vehicles after crossing and sail go back to former track, the front relative distance circuit 31a overtaken other vehicles exchanges into rear relative distance circuit 31b: the analog switch contact of action in the front start-up circuit (32a) that in the front relative distance circuit 31a overtaken other vehicles, integrating resistor is connected, rear relative distance circuit 31b interlock circuit after exchanging is switched, form commutation circuit (31b ') → (32a – 31b--31b '), relative distance display A02 relative distance simulative display from the near to the remote after completing and crossing wherein.
3., meeting cross after both sides before and after relative distance circuit exchange with overtake other vehicles cross after to sail back overtaking other vehicles of former track identical.
