The polar orientation for describing diode is consistent with word narrative order, input and output and the sense of current one of analog switch Cause.

Many object dutycycle voltages gate control method technical scheme.Figure 11 is long-range many object dutycycle voltage gating controls System diagram processed.It is constituted as shown in the figure：Including control end part：The ＇ of object selected control end 1 (wherein sets voltage from one group of drop-down Electric resistance partial pressure obtain), dutycycle setting and change-over circuit 10；Channel strip：Infrared modulated transmitting 5, infrared channel 6, infrared connect Receive demodulation 7；Actuating station part：Dutycycle-voltage conversion 8 (identical with corresponding module in digital multimeter), the ＇ of predeterminated voltage 4 (from Another group of pull down resistor partial pressure is obtained), voltage differentiate 2 ＇, the ＇ of actuating station object 3.

Circuit from left to right relevant connection in order, setting voltage conversion is modulated transmitting, 5 infrared into corresponding dutycycle Channel 6 is transferred to actuating station one by one, is converted into duty ratio corresponding through infrared receiver demodulation 7, is changed through dutycycle-voltage conversion 8 Voltage is set into correspondence, the ＇ of predeterminated voltage 4 differentiates that the corresponding of 2 ＇ compares end connection to voltage；When the setting voltage and voltage of input Discrimination ratio just has gating signal output, the corresponding execution object of control object packet when more equal compared with the predeterminated voltage at end 3 ＇.

Gating control method control principle is further illustrated with reference to foregoing angle of circumference complementary relationship：Selected in Figure 11 for object The selected control unit that the control ＇ of end 1 occurs in pairs has been made more detailed drop-down subdivision and represented：As occur in pairs control object 0a-100a, 1a-99a、2a-98a、……48a-52a、49a-51a、50a；Wherein perform object 3 ＇ be 100b, 99b ... 51b, 50b, 49b ... 1b, 0b, altogether 101 control objects；Each control object uses an independent ＇ of voltage identificating circuit 2, such as Corresponding 2-100,2-99 ... 2-51,2-50,2-49 ... 2-1,2-0；Equal difference dutycycle distribution between two adjacent objects For △ τ=1%.

In Special controlling object 0a, 50a, 100a, control object 50a differential resistance is R ∞=∞ (resistance disconnection), Control object and not paired；It is object 50a quilts when the specified all objects of setting are refused to choose only for 50a objects Choose.In addition, when two Special controlling object 0a or 100a are selected respectively, corresponding analog switch is successively closed, fixed frequency f1 The square-wave pulses of dutycycle τ 5, set 10 inputs from dutycycle and are directly grounded (resistance without differential resistance through differential capacitance 10-1 For 0)；At this moment the output of object selected control dutycycle initialization circuit 10 is respectively dutycycle τ 0a=0%, 0a=0 ° of circumferential angle alpha, and phase The dutycycle τ 100a=100% for answering angle of circumference complementary, 100a=360 ° of circumferential angle alpha；Both are angle of circumference weight on plane geometry The straight line of conjunction, i.e. X forward references axle, are in actual applications two independent controlled execution object 0b and 100b.Control Object 0a's sets voltage as 0v, and dutycycle is 0%, be the axis of abscissas of impulse waveform coordinate in itself；Control object 100a is passed through After Figure 10 NOT gates 10-3 is anti-phase set voltage duty cycle as power source voltage Vcc value in itself, on duty cycle pulse waveform coordinate Amplitude be power source voltage Vcc, parallel to the straight line of axis of abscissas.

Automatically control and meet in the motor vehicle long-and-short distant light steering indicating light that meets for dutycycle voltage gating control method below Signal show in application.

In order to realize technical solution of the present invention, before it topic be respectively arranged with before and after each motor vehicle forward, the hair of backward directions Emitter and receiver, for performing motor vehicle right lane traveling area, transmitting and receiver are arranged on before and after the left side of motor vehicle (operator seat side).

Vehicles meeting, which is overtaken other vehicles, trails the setting of duty cycle parameters and frequency in steering automaton.

Duty cycle parameters are set：

Dutycycle τ arrange parameters and its of the R-T unit running state of automotive vehicle that meets are corresponding.Agreement in embodiment It is described as follows：

Preceding transmitting：Dutycycle τ 2 meets meeting in opposite directions for two cars.

After launch：Dutycycle τ 3, τ 4, τ 6, τ 7 are that the corresponding transport condition of this car informs the back car that trailing is overtaken other vehicles And set：

1., front truck turns to and informs rear car:The front truck left steerings of τ 4；The front truck right turns of τ 6；In the front truck normally travels of τ 7；

②、τ3:Front truck, which is in launch from normal transmission τ 7 after meeting (front truck receives τ 2), front truck, is automatically converted to hair Penetrate τ 3.

It is preceding to receive：1., meeting：Two cars meet meeting, and receiver receives other side Lai Che preceding transmitting τ 2 before both sides, each Start this car meeting program, change high beam is dipped headlight；

2., rear car is trailed：The positive meeting of front truck, left steering, right turn, the preceding receiver of rear car receive what is launched after front truck τ 3, τ 4, τ 6 are travelled by trailing mode, and send the sound and light signal (referring to Figure 24) of the corresponding transport condition of front truck；

3., rear car is overtaken other vehicles：Transmitting τ 7 after front truck is received before the rear car of trailing, starts program of overtaking other vehicles, is automatically performed and overtakes other vehicles Overall process (refer to Figure 18 -- Figure 21)；Receiver is received and sent out after front truck before the positive meeting of front truck or left steering, the rear car to be overtaken other vehicles Penetrate and (be changed into from τ 7) τ 3 or the lockings of τ 4 are overtaken other vehicles program, switch to following at a distance (s2-30 exits illustrate in Figure 24).

After receive：1., front truck has the rear car of trailing：Receiver receives transmitting τ 2 before rear car after front truck, and front truck is sent【Afterwards Side carrys out car】Sound and light signal；

2. after, two car meetings cross, two cars receiver after traveling, both sides is received to be sent out after the other side left away opposite to each other τ 7 is penetrated, both sides send【Meeting is left away】Sound and light signal.

The agreement of above-mentioned dutycycle is illustrated, receives different dutycycles, both had influence on Ben Che with it is front and rear come car it is mutual Between transport condition change, also influence the change of working condition between itself automaton, in turn again influence rear car Transport condition change；Launch receive information between two cars and the transport condition of two cars is interrelated.

The frequency setting of oscillating circuit frequency dividing：

The oscillating circuit of automaton produces following divide：Fundamental frequency f0 (38kHz), dutycycle setting fixed frequency F1 (1-5kHz), transmitting-receiving periodic Control frequency f2 (100Hz).Wherein 100Hz is transmitting-receiving spacing frequency, is automatically controlled as darkening Device launches the alternate time received when either simplex is run, that is, sets 100Hz each cycle negative half period as transmit cycle, close simultaneously Interlocking is received；Positive half cycle is the reception cycle, while locking is launched.The separated purpose of transmitting-receiving is in order to avoid receiving itself infrared hair Barrier return signal is met when penetrating and causes automaton malfunction；On the other hand also for making the hair between the automaton of both sides Penetrate and receive can interactive synchronous crossing operation, the synchronous dimming lamp Chang Liang of meeting can be realized, two cars can not receive pair after crossing Square signal, recovers high beam and continues to move ahead in succession.

The transmitting-receiving either simplex dutycycle average voltage level that is received to receiving terminal of operation and compare between the preset voltage value of end Influence：Automaton is in either simplex running, only half in transmitting-receiving periodic Control frequency 100Hz each cycle The f1 pulses in cycle are transferred to other side, and the dutycycle at this moment transmitted is constant, but meet vehicle receiver demodulation after duty cycle conversion into Average voltage then halves.For example, for the dutycycle τ 4 that amplitude is 12V：Front truck left steering, trails rear car and receives τ 4 and turn The half for changing corresponding voltage average value 12V × 0.4=4.8V into is 2.4V, and at this moment corresponding predeterminated voltage should be set to 2.4V, other The situation of dutycycle is identical with this.Elaboration in this and without prejudice to text to dutycycle and its average voltage concept, only in reality Consider to halve during setting ' predeterminated voltage '.

Figure 12 is meeting long-and-short distant light automaton theory diagram.The automaton 100 of meeting long-and-short distant light (Figure 12), is mainly made up of, meeting is received preceding receiver, preceding transmitter, meeting transmitting-receiving control and three parts of oscillating circuit arrangement Hair control and oscillating circuit arrangement and preceding transmitter and preceding receiver associated connection.

Preceding receiver, it is preceding reception dutycycle discriminator circuit schematic diagram to see Figure 12 components 13, and preceding reception dutycycle differentiates electricity Road 11a includes preceding receiving demodulation circuit 7a, dutycycle voltage conversion circuit 8a and single comparator voltage identificating circuit 20a (outputs R) it is linked in sequence, the processing for receiving signal；Wherein it is preceding receive conversion after setting magnitude of voltage V1 and be made up of bleeder circuit Predeterminated voltage V10, after the mono- comparator voltage identificating circuits of V1 >=V10 are relatively consistent, low level is exported from R, is started follow-up Circuit.Predeterminated voltage V10 is the corresponding average voltages of dutycycle τ 2.Change-over circuit output s11-2a is also connected with Figure 19 Figure 24 Connect, shown for the signal that meets and start flasher circuit.Preceding receiving demodulation circuit 7a and Figure 24 signal display connection of meeting.

Preceding transmitter, the setting of transmitting dutycycle and change-over circuit before seeing in Figure 12, including preceding transmitting modulation circuit 5a with account for Sky is than initialization circuit 10a.Transmitting modulation circuit 5a is strengthened by three inputs and door, infrared power radiating circuit and infrared power before it Electrical combination is formed；Dutycycle initialization circuit 10a fixed frequency input is received and dispatched in control and oscillating circuit with meeting to be vibrated Circuit frequency dividing f1 is connected, the connected differential of (referring to the object 1a of component 10 (b) first) selected control input of dutycycle initialization circuit Resistance is directly grounded, due to without the complementary Na selected control match objects of corresponding angle of circumference, so dutycycle initialization circuit is mutually conduct a by-election Control input hanging (being not drawn into figure)；Dutycycle initialization circuit 10a exports three inputs and door of the τ 2 with preceding transmitting modulation circuit Input -- 1 is connected：For setting ' voltage setting value ' for control object, and voltage setting value dutycycle turn is carried out simultaneously Change.

-- 1, input -- 2, input -- 3 distinguishes if logic circuit has two or more input, to input.

Meeting transmitting-receiving control and oscillating circuit, including receive on-off circuit 12a, the transmitting-receiving control circuit being made up of XOR gate 16a, oscillating circuit 15a, the monostable time delay reset circuit 13a being made up of 555 time base circuits (output s13-3), output relay The associated connection of device 14.Preceding reception dutycycle discriminator circuit 11a output ends R receives and dispatches control with meeting and oscillating circuit receives switch electricity The inputs of road 12a mono- are connected；Receive switching circuitry output A and control the inputs of circuit 16a mono-, oscillating circuit with transmitting-receiving respectively 15a return-to-zero end CR (setting low level return-to-zero) is connected；Receive on-off circuit 12a output terminals As also through time-delay reset circuit 13a with it is defeated Go out relay connection.

Frequency dividing f2, f0 that oscillating circuit 15a is produced are associated with circuits below respectively：

The B (f2) of transmitting-receiving control circuit 16a inputs two；Preceding transmitting modulation circuit 5a three inputs and door input -- 2 (f0).Transmitting-receiving control

Circuit 16a processed exports three inputs and door input of the C respectively with preceding transmitting modulation circuit 5a -- 3 and reception switch Another input C of 12a are connected, and time-delay reset circuit output s13-3 is also electric with infrared power enhancing in preceding transmitting modulation circuit Road -- 4 are connected.

After above-mentioned tri- kinds of frequency dividings of f0, f1, f2 are associated with related circuit, premenstrual transmitting modulation circuit three input carries out comprehensive with door Modulation is closed, by infrared power circuit and is launched, strengthens respective infrared emission work(when meeting both sides are respectively at transmit cycle Rate, to expand infrared emission distance each other, forces other side to receive sensor and enters active region, realize that meeting both sides synchronously use instead closely Light lamp.

The A and the B of input of the input of transmitting-receiving control circuit XOR gate, carry out (the every half cycles of f2 100Hz are once) two and enter Summation operation processed；C=A+B is exported after computing, transmitting-receiving control circuit output is that C=1 automatons enter transmit cycle, Locking receives the cycle；It is that C=0 enters reception cycle, locking transmit cycle to receive and dispatch control circuit output；

On-off circuit, transmitting-receiving control circuit, oscillating circuit three are received, transmitting-receiving periodic Control frequency is produced by oscillating circuit Rate, makes reception on-off circuit and transmitting-receiving control circuit coordinates work, support is provided for transmitting-receiving either simplex operation：For (this car itself) Receive and dispatch alternate run, it is to avoid the return signal for receiving its own transmission infrared signal chance barrier causes automaton malfunction； Locking is launched when the both sides that met during meeting receive, and locking is received during transmitting, is completed meeting both sides and is synchronously converted high beam for dipped beam Lamp.

Meeting transmitting-receiving control and oscillating circuit also include time-delay reset circuit and output relay, when meeting, preceding reception Dutycycle discriminator circuit device receives the infrared signal of demodulation, for dutycycle voltage conversion setting voltage corresponding with voltage discriminating After gating (i.e. τ >=τ 2R low levels), through reception on-off circuit 12a (A low levels) and time-delay reset circuit in reception state Start output relay, control this car to become high beam into dipped headlight Chang Liang；While either simplex operation is in emission state, start The infrared power enhancing circuit of transmitting modulation circuit, makes reception before offside enter active region, forces offside meeting automatic before described Control device is acted, and both sides synchronously become high beam into dipped headlight Chang Liang；Receiver is received not before both sides after two car meetings cross To offside infrared signal, two cars recover high beam Chang Liang in succession.Voltage differentiates that duty ratio corresponding τ >=τ 2 is gated, and completes automatic Darkening.

Figure 13 is preceding reception dutycycle discriminator circuit schematic diagram (the preceding reception dutycycle discriminator circuit 11a of corresponding diagram 12).

11a shown in Figure 13, further illustrates vehicles meeting long-and-short distant light Automatic Control Theory：Preceding reception dutycycle Receiving demodulation circuit 7a is by the infrared receiving terminal module composition containing demodulation before in discriminator circuit 11a, and output R is with receiving switch electricity Road input is connected；Head normal (no infrared signal) output high level is received, through NOT gate 8-1 in dutycycle voltage conversion circuit 8a After anti-phase, then converted module 8 output s11-2a (V1) be low level (8 with digital multimeter in duty cycle conversion average voltage Module is identical), and respectively Figure 24 provides preceding receiver output infrared signal s11-2a and preparation starts Figure 19 and controls flash of light to open Dynamic circuit.The single comparator voltage identificating circuit 30-6 end of oppisite phase of V1 low levels access is exported, R high level is exported, subsequent conditioning circuit is not Action.Be referring to Fig. 6 single comparator voltage identificating circuit two in single comparator 21b.

Current receiving demodulation circuit 7a receives the outside infrared signals of dutycycle τ >=τ 2 and demodulated, and receives head and exports low electricity It is flat, be inverted into high level through NOT gate 8-1 in dutycycle-voltage conversion 8a, then converted circuit 8 be reduced into average voltage V1 >= V10, makes single comparator voltage identificating circuit output low level R=0.Want subsequent conditioning circuit to act, receive on-off circuit 12a outputs R =0, only receive on-off circuit 12a and be in reception state C=0, output A=R+C=0+0=0 is low level, time-delay reset electricity Road triggering end A triggers for low level, and monostable time delay reset circuit output s13-3 is high level, and output relay starts, normally opened Junction closure, high beam dimming lamp length is bright.Wherein R, A, C are expressed as the level of corresponding contact.

There are two and above input in logic circuit, it is necessary to avoid mutual logic from competing.

The meeting long-and-short distant light automaton course of work is described as follows：

The conversion voltage that dutycycle discriminator circuit receives the infrared signals of offside dutycycle τ 2 is received in meeting, before both sides Value is compared with preset voltage value, equal to or more than preset voltage value, through the reception on-off circuit start-up study in reception state Reset circuit acts output relay, completes vehicles meeting both sides and synchronously becomes high beam into dipped headlight Chang Liang.

Meeting Chinese herbaceous peony situation, automaton is in normally travel and (does not receive outside infrared signal R=1)：Before connect It is high level R=1 to receive dutycycle discriminator circuit output end, no matter C=0 or C=1, be that the reception of OR gate is opened when being alternately present Powered-down road 12a output ends have：A=R+C=1+0 (1)=1, subsequent conditioning circuit does not start；Reception on-off circuit 12a output terminals As= 1 and transmitting-receiving control circuit 16a XOR gates input one is fed back to, transmitting-receiving cycle of another input two of XOR gate by oscillating circuit 15a Control frequency f2 controls：

B=0, A=1 when receiving and dispatching periodic Control frequency f2 and being negative half period, there is C=A+B=1+0=1 (XOR gate binary systems Summation operation), the input of transmitting modulation circuit three is in opening state with door before C=1 makes, and preceding radiating circuit is in transmit cycle, Automaton is in emission state；At this moment no matter whether preceding receiving circuit receives outside infrared signal (R is any value), C=1 lockings OR gate receives on-off circuit, i.e., locking is received when automaton is launched in itself, is received while being also avoided that The return signal that its own transmission infrared signal meets barrier causes automaton malfunction；

The B=1 when receiving and dispatching periodic Control frequency f2 and being positive half cycle, normally runs R=1, A=1, and transmitting-receiving control circuit has C The input of transmitting modulation circuit three is in latch like with door before=A+B=1+1=0 (XOR gate binary system summation operation), C=0 make State, stops transmitting, and automaton is in reception state, and locking is launched when automaton is received in itself.Therefore, it is motor-driven Car individually travels its own transmission also can alternate run with receiving；

Process as described above R=1, no matter B=1 or 0 has A=1, and output relay does not start, high beam Chang Liang.

Receiver receives outside infrared signal R=0 before automaton：

This car is met with other side Lai Che during meeting, and Ruo Benche infrared receiving terminals take the lead in receiving offside infrared signal τ=τ 2, Preceding reception dutycycle discriminator circuit output R=0, is also at reception cycle C=0 simultaneously when receiving on-off circuit this moment, (is in receipts The reception state of bill labour movement row) receive switching circuitry output A=R+C=0+0=0A=0 control following circuit respectively：R= 0, voltage identificating circuit 20a export R low levels, and transmitting-receiving control circuit output end A is low level, the output of start-up study reset circuit High level (s13-3) and the reset (preventing critical condition unstable) in 0.5-1.0 seconds that is delayed；Output relay is acted, normal opened contact Closure, this car becomes high beam into dipped headlight Chang Liang (automatic beam change process)；A=0 oscillating circuit failure of oscillation return-to-zero, all frequencies are reset B=0 (vibration reset terminal resets for low level, i.e., circuit stops oscillation), C=A+B=0+0=0C=0, transmitting-receiving control circuit is defeated Go out for low level, be this car the reception cycle start it is synchronous with offside transmit cycle (point of penetration synchronous with opponent vehicle Ben Che, It is exactly not the starting point of offside transmit cycle).From this moment on, this car receive the cycle length only with other side's meeting The transmit cycle ' beginning ' of automatics is synchronous (Yin Benche oscillating circuits failure of oscillation, unrelated with this car oscillating circuit), until right Square vehicle emissions end cycle, this car (recovers A=1) untill not receiving infrared signal, the starting of oscillation again of this car oscillating circuit, institute It is low level to have half cycle before a cycle of frequency dividing, and transmitting-receiving periodic Control frequency f2 is still in B=0, C=A+B=1+0= 1C=1 this car transmit cycles start, and the opponent vehicle reception cycle starts, both sides automaton synchronous with this side transmit cycle Reiving/transmitting state in Vehicle during Crossing Event is on the contrary, both sides are alternately mutually in step in operation in transmitting-receiving.

Infrared power enhancing circuit (time-delay reset electricity in transmitting modulation circuit before starting while this car transmit cycle starts Road has acted and has been delayed, startup power enhancing circuit), the infrared emission power of this car is increased, expands this car transmitting range, forces Receiver enters active region before opponent vehicle, and synchronism switching high beam is dipped headlight Chang Liang to other side's automaton immediately.This The section time is less than the half 0-5ms of f2 (100Hz) a cycle；Because this car automaton might not be in opponent vehicle The infrared signal for just receiving other side's transmitting at the very start of transmit cycle, therefore during both sides' automaton successive relay trip Between be respectively less than 5ms, the reaction speed 20ms of human eye, it is possible to the both sides' high beam for thinking meeting is synchronous dimming lamp.

Opponent vehicle meeting automaton is received after the enhanced infrared signal synchronous action of this car, subsequent offside Also offside itself infrared emission power can be increased while being in transmit cycle, force the meeting automaton that meets first to act That side can also receive enhanced infrared signal；By the infrared light path and respective circuit of both sides, form double Closed loop positive feedback effect between square automaton, overcomes two cars and is meeting the action of critical condition automaton not Stability；The reception cycle phase of the automaton of both sides is all after the transmitting for being synchronized with opponent vehicle in Vehicle during Crossing Event simultaneously Phase, emission state and reception state between two car automatons is in interactive synchronous operation, overcome meeting Both sides meet between process automaton because receiving sensitivity or transmitting range have differences, it is to avoid may be because motor-driven The high beam switching of car both sides is asynchronous and brings the dazzling disadvantage of dazzle.After two cars cross, receiver is not received before both sides To square signal, two car automatons reset recovers high beam Chang Liang in succession.

Above-mentioned meeting automaton, realizes meeting both sides real-time synchronization and becomes high beam automatically into dipped headlight, both kept away Exempt from dazzling, can also reduce driver's manual labor intensity, overcome nervous degree during meeting, especially to new hand for driving a car, favorably Meeting traffic safety；Locking is received when being launched due to the automaton, can be avoided receiving itself infrared chance barrier again and be returned A disadvantage for malfunction occurs for letter in reply number.

Rear car signal control device block diagram is informed in the steering of (sheet) car before Figure 14 is.

Front truck (or this car) turns to and informs rear car signal control device 300 (Figure 14), each motor vehicle left back peace Equipped with rear transmitter and rear receiver, by launching thereafter after receiver steering, meeting, the information such as overtake other vehicles are informed into rear car, and Realize that transport condition exchanges information with receiver before the preceding transmitting of rear car.

The context that described in fig. 14 ' front truck ' is meant when meeting in position relative to ' rear car ' each other；When Refer to that ' this car ' appears in have after this Chinese herbaceous peony more and carry out car, and quoted during this car of independent narration.

See right turn lamp control circuit in Figure 21, be made up of NOT gate 50-4, diode D2, D3, resistance R5 and sail go back to former track High beam automatic restoring circuit：NOT gate 50-4 constitutes loop between being serially connected in two backward dioded D2, D3, be connected to s40-1 with Between controllable silicon SCR charging capacitor C1 positive poles；Figure 24【There is car at rear】Signal s2-20b is through resistance R5 NAND gate 50-4 inputs It is connected.It is intended to before overtaking other vehicles receive dutycycle τ 7, overtaking steering lamp start-up circuit s40-1 is low level, and 50-4 output high level leads to Backward dioded D2 isolation is crossed, on charging capacitor C1 without influence；If the tailstock now to be overtaken other vehicles has pursuit-type vehicle again, after receive τ 2 has s 2-20b to be high level, is connected through resistance R5, diode D3 with s40-1, and s40-1 has been low level, NOT gate 50-4 outputs High level is constant.Overtake other vehicles after crossing, no signal is received 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 has s2-20b to be high level, and s40-1 is high level again, and diode D3 two ends are high level, NOT gate 50- 4 output low levels, SCR charging capacitors C1 instantaneously discharges residual charge, and controllable silicon is blocked, and extinguishes right turn lamp, automatic to recover remote Light lamp Chang Liang；Car is not trailed for the rear overtaken other vehicles, situation is the same.

Overtake other vehicles long-and-short distant light steering indicating light automatic control process explanation：

Before overtaking other vehicles, pursuit-type vehicle is at a distance of 150 meters of front truck with remote, and preceding receiver receives the infrared signals of τ 7 launched after front truck Not in infrared sensor active region, the τ 7 received is intermittent imperfect infrared sequence pulse signal, through dutycycle electricity Pressure is converted to the average voltages of 0 ＜ τ ＜ τ 7, until the meeting automaton action s13-3 for receiving the rear cars of τ 2≤τ ＜ τ 7 is High level, output relay starts：

1., normal opened contact closure becomes high beam into dipped headlight, and rear car presses following at a distance during this, though meet automatic beam change bar Part, now front truck meeting not with travelling in the same direction.Meet the regulation of ' high beam must not be used by closely travelling rear car '.

2. the analog switch 30-3 closures of the disconnected on-off circuit of delay in, normal opened contact closure s14-2 high level, Figure 19, but Now there are τ ＜ τ 7, single comparator voltage identification 30-6 outputs s13-4 to continue to high level, relay maintenance always action State is constant.

Rear car is front truck to be surmounted close to front truck purpose, and when two cars continue close to about 150 meters or so, receiver connects before rear car Receive the complete infrared pulse signals of the τ=τ 7 launched after front truck, Figure 19 be in Duty ratio control flash of light start-up circuit digital ratio compared with Device voltage identificating circuit 30-6 exports s13-4 low levels；Start instead in meeting automaton output relay changeover contact In this period switched again, because Figure 20 be in overtaking steering lamp start-up circuit sampling time delay circuit 1,2 while exporting high level And be delayed, its NAND gate 40-1 is exported the steady low levels of s40-1；NOT gate 40-2 exports the stable high level of s40-2, controls respectively System：

1., the stable high level of s40-2, left steering lamp power circuit control end is high level, and left steering lamp starts and dodged It is bright；

2., the stable high level of s40-2, lamp control circuit charging electricity is turned to the right through isolating diode D1 resistance R3 moments Hold C1 fully charged, it there are enough discharge times；Controllable silicon SCR is blocking state, is prepared to open right turn lamp；

3., the steady low levels of s40-1, are to trail electric capacity 60-5 in delay startup circuit to discharge through Figure 22, ' timing of overtaking other vehicles ' Start.

Meeting automaton output relay changeover contact switches repeatedly in overtaking process, when output relay is normally closed Steering indicating light flashing power source is provided for high level after contact s14-1 closures, s40-2 high level lights left steering lamp 50-01；Output after The normally closed normal opened contact of electrical equipment disconnects to be closed again, and conversion uses long-and-short distant light.This overtaking process meets traffic safety law and implements bar The 47th article of regulation on ' during overtaking, left steering lamp, conversion should be opened in advance and uses high-low beam light ' of example.

Said process continues up to front and rear two motor vehicles and crossed, and the driver that at this moment overtakes other vehicles has started to left steering and leaves former track Continue from front truck left overtaking, the preceding receiver overtaken other vehicles does not receive the infrared signal launched after front truck, and output relay is normally opened After contact s14-2 is returned, the output low level of Figure 20 sampling time delays circuit 2, NAND gate 40-1 outputs s40-1 sports high level, S40-2 is changed into low level：

1., s40-2 is changed into low level, and left steering lamp power circuit control end dead electricity, left steering lamp is extinguished；

2., s40-1 sports high level and triggers controllable silicon S through electric capacity C2_CRControl pole k, controlled silicon conducting, discharge resistance It is high level on R4, s50-1 high level is exported through two NOT gate 50-3,50-2, opens right turn lamp 50-02 glittering；Charging capacitor C1 starts electric discharge, and ' sailing back former track timing ' starts；Infrared signal is lost because two cars cross to be intended to overtake other vehicles, after right turn lamp is lighted, Isolating diode 30-2s of the s50-1 through Figure 19 Duty ratio controls flash of light start-up circuit, continues to the work of flash of light start-up circuit, Export s13-4 low levels；Now Figure 13 s11-2a no signals, export s50-2 by Figure 21 NOT gates 50-3 and maintain to be delayed in Figure 18 Reset circuit triggering end low level, output relay continues to switching, continues on right turn lamp, conversion and uses instant and near light Lamp.

Be intended to overtake other vehicles cross after continue to overtake other vehicles and start to surmount front truck, sail back behind former track, after receive and launch before passed vehicle τ 2 have s2-20b be high level, sail back original track automatic restoring circuit NOT gate 50-4 export low level, make charging capacitor C1 strong System electric discharge ends, and controllable silicon recovers to block, and ' sailing back former track timing ' terminates, and s50-1 is changed into low level, right turn lamp power electricity Road control end dead electricity, right turn lamp extinguishes；S50-2 is changed into high level, and Figure 18 time-delay reset circuits triggering end is recovered high level, prolonged When reset circuit reset, output relay dead electricity normally closed contact is returned, and recovers high beam Chang Liang, and completion is overtaken other vehicles overall process.

The law on road traffic safety implementing regulations the 47th article described above that meet are on ' rear car should confirm there is abundance Safe distance after, from front truck left overtaking, after necessary safe distance is pulled open with passed vehicle, open right turn lamp, sail back Former track ' regulation.

That trails is intended to overtake 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 sudden strain of a muscle for a long time It is bright, to the adverse effect for front and rear the driving vehicle driver vision that is intended to overtake other vehicles, understand automatically when this period is intended to overtake other vehicles more than about half a minute Into following at a distance.See Figure 22, the trailing dipped beam lamp control circuit is by trailing delay startup circuit and trails control circuit group Into, between association link.

Trail delay startup circuit：Trail delay startup circuit input and Figure 20 overtaking steering lamp start-up circuit output ends S40-1 is connected, and is connected and exported, charging diode with the electric capacity 60-5 integrating circuit constituted and NOT gate 60-2 by resistance 60-4 60-3 is in parallel with resistance 60-4, and composition fills slow play delay circuit soon.

Trail control circuit：Trail control circuit to be made up of bistable trigger 60-1, NOT gate 60-2 output end is through electric capacity 60-9 and grounding resistance 60-10 composition differential circuits are connected to bistable trigger 60-1 triggering end 1C, bistable trigger output end 1Q (s14-5) is connected with the OR gate s14-5 of Figure 18 meeting automaton output relays；Direct clear terminal 1R is passed through respectively Resistance 60-7 is connected with positive supply, and it is that signal is controlled in display circuit block diagram to be connected to Figure 24 through electric capacity 60-6【There is car in front】 Sound and light signal s60-1.

In Figure 22, B10 is overtake other vehicles recovery button and 60-11 control angle sensor parallels, while accessing positive supply with touching Start between 1C, trailed for manually or automatically terminating rear car, restart program of overtaking other vehicles.

Overtake other vehicles into following at a distance dipped headlight control process explanation：

Rear car starts to overtake other vehicles s40-1 for low level, and from this moment, the electric capacity 60-5 for having been filled with electric charge starts through resistance The slow back discharges of 60-4, trail delay startup circuit and start ' timing of overtaking other vehicles '；When capacitance voltage slowly declines, setting delay is super Cross designated time (about half a minute), NOT gate 60-2 input voltages reach low level turnover voltage, high level is exported, through differential capacitance 60-9 produces first positive pulse on resistance 60-10, and triggered end 1C overturns bistable trigger 60-1, output end 1Q S14-5 is changed into high level, and ' timing of overtaking other vehicles ' terminates, and stops overtaking other vehicles；Output relays of the s14-5 through meeting automaton 100 Device OR gate diode 14-4, makes output relay be constantly in pressure operating state, and contact stops switching, and normal opened contact closure is near Light lamp Chang Liang, automatically into following at a distance：

1., because output relay changeover contact stops toggling, Figure 20 is overtaking steering lamp start-up circuit NOT gate 40- 2 output s40-2 low levels, left steering power circuit control end dead electricity, left steering lamp is extinguished；

2. it is low level that, relay normally closed contact, which disconnects s14-1, and steering indicating light loses flashing power source, and left steering lamp dead electricity is stopped Dodge；Relay normally open contact closes dipped headlight Chang Liang, terminates overtaking process, is travelled automatically by trailing mode.

Meet traffic safety law implementing regulations ' when the rear car of equidirectional traveling and front truck are closely travelled during trailing, must not Use high beam ' regulation.It is this automatically into trailing mode also comply with urban highway traffic it is crowded when, the motor vehicle mutually trailed Transport condition.

At this moment overtaking steering lamp start-up circuit NAND gate 40-1 exports s40-1 high level, and right turn lamp control circuit is controllable Silicon may be turned on, at this moment because of meeting output relay normally closed contact disconnection s14-1 low levels, right turn flick of lamp power loss, Will not malfunction.

During trailing, current vehicle sailed out of former track (including sail it is remote or turn to leave away), this vehicle device motor-car meets letter Number control display circuit【There is car in front】S60-1 signal terminatings (see explanation in Figure 24), direct clear terminalProduce negative arteries and veins Punching, make bistable trigger 60-1 return-to-zero, output end 1Q s14-5 are changed into low level, while be intended to receiver before overtaking other vehicles do not receive it is red External signal, output relay normally closed contact closure, high beam recovers Chang Liang automatically, and motor vehicle is automatically into normally travel state.

When overtaking other vehicles into during trailing, driver has found there is chance of overtaking other vehicles, and is equipped with angular transducer 60-11 side Turned to the left to disk when getting to some angle, triggering end 1C is accessed positive supply and produce second positive pulse, recover bistable triggering Device 60-1 output ends 1Q is low level, terminates following at a distance, reenters transport condition of overtaking other vehicles；Or control panel is clicked manually Upper setting【Recover the button B10 that overtakes other vehicles】, second positive pulse can also be produced by triggering end 1C is accessed positive supply, recovered bistable and touched It is low level to send out device 60-1 output ends 1Q, trails to receive still to receive before rear car and launches τ 7 after front truck, can also restart and overtake other vehicles Program.

Motor vehicle described above meets, and all whole car lights can realize automation for meeting, the traveling process such as overtake other vehicles, trail, It instead of【The law on road traffic safety】In legal motor vehicle meet process whole it is manually operated；At this moment driver can be just thought of with both hands Steering wheel is held, other operations without considering hand both reduced labor intensity, nervous degree can be overcome again, and can also reduce people Judged by accident for malfunction, especially favourable Getting Started, the serious accident such as effectively prevent to bump against or knock into the back occurs, and improves road Rate, produces obvious social benefits.

Figure 23 is dense fog button connects figure：It is more than the spy of visible ray using transmitance of the infrared light in dense fog or haze Property, by by lower band mechanical latching or self-sustaining【Dense fog button】B20, can make transmitting modulation before and after this car automaton Infrared emission power increase in circuit is to the maximum of design, and the transmitting range of infrared light, is carried as far as possible before and after further expanding Preceding advance notice is met the sound and light signal of transport condition between vehicle.This is at night, and the especially visibility such as dense fog wind and snow haze is extremely low Bad weather, motor vehicle energy is understood the transport condition of front and rear adjacent vehicle mutually, then by of short duration voice message sound, can and When remind driver take care, to running into driver's insobriety, such as drink, morning is tired, it is absent-minded situations such as, can be effective Preventing collision from knocking into the back etc., serious accident occurs.

Motor vehicle meet signal control display device 400 be made up of signal control device and signal display control panel.

Figure 24 is signal control display circuit block diagram.

As shown in figure 24, signal control device includes：Signal control circuit and signal display circuit；From left to right successively For：Front and rear demodulation change-over circuit 11a, 11b--- voltage identificating circuit, signal control circuit, the signal of receiving of peripheral circuit is introduced to show Show circuit associated connection.Wherein signal display circuit includes signal display circuit for lamp and display vehicle running state.

Signal control device introduces forward and backward receive from the related automaton of automatic Pilot auxiliary control appliance and demodulated Change-over circuit, it exports the unified input of the voltage identificating circuit of access signal control device, exported through signal control circuit End is connected with corresponding signal display circuit, all voltage signals for collecting and transmitting the acquisition of this car actuating station, control point Bright display lamp, shows that this car and this car meet transport condition, direction position and the relative distance simulative display information of vehicle.

Signal display control panel, forms mark icon by signal display lamp and is arranged on control panel, it is up and down Mutual alignment and this car all around carry out car physical location one-to-one corresponding.Narration in detail in detail below：

1), preceding to receive demodulation change-over circuit 11a, it is 20% to receive dutycycle ..., and 70% voltage signal is simultaneously converted into phase Magnitude of voltage output (s11-2a) should be set, one is unified defeated once voltage identificating circuit 2-20,2-30,2-40,2-60,2-70 respectively Enter end, compared with the dutycycle τ 2 that each electric resistance partial pressure point is constituted, τ 3, τ 4, τ 6, the corresponding predeterminated voltages of τ 7, and will be equal Signal gating output, through signal control circuit, respectively with the signal display lamp (including holding circuit) of signal display circuit Hold correspondence：

Signal display lamp is illustrated：【This car meeting A3】With the corresponding display light signal of heavy line collimation mark note in display lamp, figure； The corresponding voice signal sent is noted with fine dotted line collimation mark in ' this car meeting ' voice message, figure；During ' two car meetings ' transport condition, The vehicle running state for showing the signal is noted in figure with fine line collimation mark, other are same.

Wherein front truck, which is turned to, informs that rear car light shows signal：【Front truck left steering A7】(τ4)、【Front truck right turn A8】(τ6)、 【The positive meeting A9 of front truck】(τ 3) at the same also with【There is car A6 in front】It is associated, it is to inform that trailing rear car light shows signal；

' rear car of trailing ' is shown：【There is car A6 in front】Also dipped beam lamp control circuit s60-1 is trailed with Figure 22 to be connected, be used for Front truck is left away the signal terminating, and the rear car dipped headlight for recovering to trail is high beam Chang Liang, into normally travel state；

' trailing is intended to overtake other vehicles ' shows：【The positive meeting A9 of front truck】(τ3)、【Front truck left steering A7】Exported after (τ 4) associated connection S2-30 is connected with Figure 18 meeting automaton output relays：For

1., during ' two car meetings ' both sides show simultaneously【This car meeting A3】(τ 2), passes through this car in s2-20 and this car Figure 14 Steering informs that rear car ' object selected control circuit ' is connected, and dutycycle is launched after making during this car meeting and is changed into τ 3 from τ 7 automatically；It is intended to surpass Chinese herbaceous peony receiver receives dutycycle τ 3, through being sent in rear car Figure 24【The positive meeting A9 of front truck】Connect s2-30；Simultaneously through s2-30 Make rear car Figure 18 force the output relay to be overtaken other vehicles to be overtaken other vehicles from a direct acting, termination is switched to repeatedly, rear car is entered trailing Transport condition；

2. dutycycle τ 4, is launched during front truck left steering thereafter, the preceding receiver of rear car receives dutycycle τ 4, through being intended to overtake other vehicles Sent in Figure 24【Front truck left steering A7】While (τ 4), equally make to be intended to overtake other vehicles into following at a distance state through s2-30.

It is clear in order to describe, between each circuit of signal control circuit that met described in omission by isolating diode (in figure Draw) description of associated connection, Figure 24 is referred to, it is as follows.

Receiver receives 0 ＜ τ ＜ τ 7 by during near before meeting automaton, it may appear that τ 2nd ... average voltage moments of τ 6；So that sounding optical signal by mistake is prevented, using delay one second, just after can be sent after signal stabilization Acoustic-optic indicator.

2) it is, rear to receive demodulation change-over circuit 11b, receive dutycycle τ 2, τ 7 and be converted into the output of respective settings magnitude of voltage (s11-2b), difference one is corresponding with dutycycle τ 2, the τ 7 that each dividing point is constituted once voltage identificating circuit 2-20b, 2-70b Predeterminated voltage is compared, and equal signal gating is exported, and circuit is controlled through corresponding signal, respectively with signal display circuit In ' front truck of pursuit-type vehicle ' show【Back car A5】After τ 2, ' two car meetings cross ' both sides show【Meeting is left away A4】The phases of τ 7 Correspondence；

Also【Meeting is left away A4】With it is above-mentioned【This car meeting A3】Simultaneously with signal display circuit【Two car opposite direction A2】 Optical signal is associated；Also【Back car A5】With it is above-mentioned【There is car A6 in front】Simultaneously with signal display circuit【Two car Tongfangs To A1】Optical signal is associated.

3), relative distance is met front truck relative distance circuit 31a in signal display circuit【Front truck relative distance shows Show】A01, rear car relative distance circuit 31b【Rear car relative distance is shown】The corresponding sound and light signals of A02 are shown, are faced for front and rear Nearly vehicle relative distance simulative display.

4), voice warning circuit B00, including voice generation circuit；Of short duration voice message has：【This car meeting B3】 (see of short duration voice message is noted with fine dotted line collimation mark in Figure 24, as follows),【Meeting is left away B4】、【Back car B5】、【Front has Car B6】、【Front truck left steering B7】、【Front truck right turn B8】、【The positive meeting B9 of front truck】Deng；Shown simultaneously in the optical signal that meets, hair Go out corresponding of short duration voice message, inform before and after driver to have and carry out car, drive with caution；Equally exist【Relative distance is shown】Optical signal While display, it is additionally provided with and sends of short duration voice message：【Front (rear), which has, carrys out car！Drive with caution！B01(B02)】.

Voice message signal shows that the connection of signal is omitted with corresponding lamp in Figure 24, it is not excluded that utilize other nothings therebetween Line mode is associated, such as radio, bluetooth, ultrasound, Infrared Transmission voice signal.

Relative distance display circuit principle is described in detail before and after in Figure 24.

Relative distance is shown：Including【Front truck relative distance is shown】A01、【Rear car relative distance is shown】A02.Distance display Circuit is by level indicator (using volume indicator module such as AN6884 is shown) and multiple (5,7,9,12) luminous tube structures Higher into the nearlyer level indicator output level of, two cars distance, the number that luminous tube is lighted is more, the number that luminous tube is lighted with Relative distance is inversely proportional, and realizes that relative distance analog signal is shown.

Relative distance light shows signal principle：Have after this Chinese herbaceous peony and carry out car, with this car at a distance of 150 meters with remote, what is received is red External signal not regulation range of receiving in, after this Chinese herbaceous peony receiver reception head receive before and after come car (meeting, steering, trailing, Overtake other vehicles) front and rear transmitting ＜ τ 2 ... the ＜ τ 7 of dutycycle 0, be intermittent imperfect infrared pulse sequence, so duty Than voltage conversion into average voltage very little.

See that Figure 24 is first set, front and rear demodulation change-over circuit 11a, 11b output s11-2a, s11-2b of receiving reflects without overvoltage Other circuit, respectively directly with the signal display circuit that meets【Front truck relative distance shows A01】、【Rear car relative distance A02】Phase Connection, is shown in choice refreshments dotted line in figure.Just start【Front and rear relative distance is shown】1-2 luminous tube can only be lighted or unstable glittering, Start interval to send【Have and carry out car！Drive with caution！】Of short duration voice message.When dutycycle voltage conversion not yet reaches τ 2nd ... τ 7 corresponding average voltage level,【This car meeting A3】……【Back car A5】Or【There is car A6 in front】Signal is non-lit up Before, in the case where visibility is relatively low, although do not know to carry out the specific distance of car, but always will appreciate that there is car at front or rear Face, intermittently send voice message, as early as possible driver can be reminded to drive with caution；Especially before dawn driver it is tired or it is drunk it When, this prompting is very important.

Current car later continues close to this car in 150 meters, can receive the infrared signal of complete (saturation), light luminous Pipe number is only corresponding with the dutycycle received, sends【This car meeting A3】Or【Back car A5】、【There is car A6 in front】Deng sound Light is shown, while also sending corresponding of short duration voice message, can confirm that fore-aft vehicle has closed on, this car, which should try one's best, to be avoided to the right, Warning driver need to drive with caution.

Because receiving saturation infrared signal in this section of distance, the luminous tube quantity lighted is corresponding with dutycycle, and front and rear The relative distance for carrying out car is unrelated；On the contrary, when rear car is in this segment distance for trailing front truck, transport conditions different for front truck are (preceding Car normally travel, meeting, steering), even in same distance, rear car receives different duty and lights the luminous of varying number Instead pipe, rear car driver is mistakenly considered far and near different from the relative distance of front truck, causes erroneous judgement.

To carry out car before and after realizing in 150 meters of predetermined distance by as far as near, and the relative distance after crossing from the near to the remote The simulative display that the luminous tube quantity that simulative display, i.e. relative distance circuit are lighted in showing is inversely proportional with relative distance, with reference to Figure 24, Figure 25 are explained：

1., meeting is overtaken other vehicles trailing, and two cars are by as far as nearly close to each other, relative distance simulative display：

It is signal control display circuit block diagram to see Figure 24.The signal that met in figure control display device also include front truck it is relative away from From circuit 31a and rear car relative distance circuit 31b.

Front truck relative distance circuit 31a signals receive head 7a-- by being received before peripheral Figure 13 in demodulation change-over circuit 11a S11-1a is introduced, through monostable circuit 9a ' (such as time base circuit 555 is constituted), dutycycle voltage conversion circuit 8 ', integrating circuit rc (integrating resistor r is in parallel with backward dioded d) and【Front truck relative distance is shown】A01 is constituted and is linked in sequence.

When this car reception head receives complete infrared pulse signal, band constant time lag is triggered using positive pulse rising edge is exported Monostable circuit 9a ', no matter in τ≤τ 7 any dutycycle, output band the positive broad pulse of constant time lag.It is assumed that constant time lag (pulsewidth) 0.7ms (such as 1kHz dutycycles τ 7), at this moment Ben Che occur with carrying out car process (including meeting, overtake other vehicles, trail) of meeting Different duty τ 2 ... τ 7, fixed pulse width is converted into by maximum duty cycle τ 7 through monostable circuit delay, the voltage being converted into Average value is a fixed value；Carry out car close in 150 meters, integrated Schaltkreis c charging processes are added in the electricity that relative distance is shown Pressure is slow to be risen, and the luminous tube quantity lighted gradually increases, and indirect analog shows that carry out car approaches this car gradually.When speed is The cars of 100km/h two are met and need 2-3s, and rc time constant is set into about 2.5s.End, light in this period【Front truck it is relative away from From display A01】Whole luminous tubes.Meet motor vehicle and meet process by as far as near relative distance simulative display.

Two cars cross, it is impossible to receive to square signal, integrating capacitor electric charge is quickly reversed electric discharge through diode,【Front truck phase Adjust the distance display A01】Extinguish.

Rear car relative distance circuit 31b signals receive head 7b-- by being received before peripheral Figure 14 in demodulation change-over circuit 11b S11-1b is introduced, and structural principle is identical with front truck relative distance circuit 31a.

2., meeting is overtaken other vehicles cross after, two cars are mutually left away from the near to the remote, relative distance simulative display：

It is described above to address only vehicles meeting, overtake other vehicles, trail luminous tube quantity and phase by being lighted as far as near procedure Adjust the distance and be inversely proportional.Two cars are left away opposite to each other after being crossed for meeting, and both sides show by preceding relative distance circuit, relative after being changed into Shown apart from circuit；It is intended to overtake other vehicles after crossing for overtaking other vehicles and the front and rear parking stall of passed vehicle is exchanged, passed vehicle is by rear relative distance electricity Road shows that relative distance circuit is shown before being changed into, and is intended to overtake other vehicles then opposite.Both the above situation is met to two cars cross after, it is front and rear Relative distance circuit shows and exchanged.Sail go back to former track due to being overtaken other vehicles after crossing, two cars that meet close on that to receive saturation red External signal, at this moment the preceding relative distance circuit of passed vehicle or the rear relative distance circuit overtaken other vehicles should export maximum level, two car phases The light emitting diode of display of adjusting the distance should be lighted all.By being passed through in the nearly relative distance circuit that meets between obvious above-mentioned two car Cross integrating circuit, it is impossible to directly 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, referring to Figure 25 be meet cross after relative distance show mutually Circuit arrangement (being introduced by Figure 24 parts) is changed, relative distance circuit 31a, 31b integrating resistor before or after being introduced from periphery, by correspondence Comparator F, analog switch M_0-3Constitute start-up circuit 32a, 32b that display is exchanged.

When motor vehicle meets and crossed, two Chinese herbaceous peonies or rear receiver that original receives infrared signal lose signal, and it is integrated Reversely discharged soon from maximum level on electric capacity c, reverse current is produced on integrating resistor r, using accessing on the integrating resistor Comparator output starts analog switch M₁-₃, its contact carries out to interlock circuit in the opposite side phase relative distance circuit after exchange Switching, the opposite side after being exchanged from the near to the remote after being crossed for satisfaction completes relative distance simulative display.

Motor vehicle meets cross after relative distance show interchange circuit principle：By taking overtaking process as an example, with phase after passed vehicle Adjust the distance circuit 31b interlock circuits and relative distance circuit 31a is specifically described before switching to after crossing, other two cars meet When situation it is identical.

Relative distance shows that interchange circuit has, relative distance behind the side of the start-up circuit 32b of passed vehicle before crossing The comparator F outputs being connected in circuit 31b with integrating resistor r two ends by polarity and analog switch M (_1-3) control end be connected；Surpassed The switching circuit (31a ') of car analog switch contact M in analog switch M_1-3, to crossing after opposite side (preceding) relative distance circuit Interlock circuit switches over to be formed in (31a)：M1, which makes 555 reset terminals 4. be grounded (reset), makes it export low level, for locking Monostable circuit；Power supply is connected through M2, electric capacity c1 with integrating capacitor c, and acting backward integrating capacitor c for analog switch is instantaneously full of Electric charge；M3 is connected from comparator F positive input terminal through discharge resistance r1 with the integrating capacitor c of (preceding) relative distance circuit (31a), Electric capacity c high level is set to maintain the comparator of start-up circuit to continue to output high level；Set the r1c more a length of 5- of time constant 6s, because this car of section two departure proess of overtaking other vehicles will be grown compared with meeting close to process.The integrating capacitor c voltages of this discharge process gradually under Drop, makes the light emitting diode quantity that (preceding) relative distance circuit (31a) is lighted be inversely proportional with two workshop relative distances.Until two Car is located remotely from each other, and integrating capacitor c electric discharges end, and comparator is resetted (output low level), and whole relative distance shows process knot Beam.

It is not drawn into isolating the pole of isolation two that the front and rear level of switching should add in order to clearly briefly explain, in foregoing circuit Pipe.

Overtake other vehicles close to before passed vehicle, be not by following at a distance, it is and quick by as far as nearly pursuit in the same direction in people having a common goal；This and Overtake other vehicles and former track sailed go back to after crossing, people having a common goal quickly leaves away from the near to the remote in the same direction, both meet traveling of the situation in 150 meters when Between be identical 5-6s, and both in 150 meters time 2.5s of meeting it is many slowly.Above two is completed using same circuit Period, it is described below：

Referring to Figure 25, switching circuit 31a ' is mutually changed into front and rear relative distance circuit 31a--31b -- 31b ' integrating resistor Series resistance ro is in parallel with the analog switch Mo contacts set in r1；Analog switch Mo is controlled by Figure 24 signals and shown【The meeting of this car Car A3】s2-20.Analog switch Mo is acted only in meeting, and minimum resistance is presented in short-circuit series resistance ro, is obtained most in short-term Between.Other transport conditions, analog switch Mo is failure to actuate, and obtains the long period.Can so meet different transport conditions it is relative away from From simulative display.

In summary describe, the relative distance breadboardin after being crossed with reference to Figure 24 and Figure 25 to motor vehicle is shown briefly It is bright：

1., overtake other vehicles and former track is sailed go back to after crossing, the rear relative distance circuit 31b of wherein passed vehicle mutually changes preceding relative distance into Circuit 31a：The mould acted in the rear start-up circuit 32b that integrating resistor in the rear relative distance circuit 31b of passed vehicle is connected Intend make and break contact, the preceding relative distance circuit 31a interlock circuits after exchange are switched over, formation switching circuit 31a ' → 32b--31a--31a ', wherein preceding relative distance shows that A01 completes relative distance simulative display from the near to the remote after crossing.

After former track is sailed go back to when overtaking other vehicles, still there are pursuit-type vehicle, rear relative distance circuit 31b integrating resistors in the rear of passed vehicle In positive potential, comparator output low level, analog switch is resetted, and causing the preceding relative distance circuit of passed vehicle, (31a ' is gained Integrating capacitor c 31a) is in high level, recovers normal display, lights a greater number light emitting diode.Other transport condition classes Seemingly.

2., similarly, overtake other vehicles and former track is sailed go back to after crossing, the preceding relative distance circuit 31a overtaken other vehicles mutually changes rear relative distance into Circuit 31b：The simulation acted in the preceding relative distance circuit 31a overtaken other vehicles in the connected preceding start-up circuit (32a) of integrating resistor Make and break contact, is switched over to the rear relative distance circuit 31b interlock circuits after exchange, and formation switching circuit (31b ') → (32a -31b--31b '), wherein rear relative distance shows that A02 completes the relative distance simulative display after crossing from the near to the remote.

3. before and after the both sides after, meeting crosses relative distance circuit exchange with overtake other vehicles cross after sail go back to original track and overtaken other vehicles It is exactly the same.

Cross-connect cable 32b- before and after shown in Figure 24 between relative distance circuit 31a--31b and corresponding start-up circuit 31a-31a ', (32a-31b-31b '), form corresponding switching circuit 31a ', (31b ')；Bracketed mark in Figure 24, Figure 25, Describe to overtake other vehicles after crossing and mutually change the situation of corresponding switching circuit (32a-31b-31b ') into by preceding relative distance circuit 31a； The mark of unbracketing in figure, describes passed vehicle and mutually changes corresponding switching circuit 32b- into by rear relative distance circuit 31b 31a-31a ' situation.Wherein in switching circuit 31a ', (31b ') contact containing analog switch structure is in meeting or overtakes other vehicles from remote To nearly process of meeting, the simulative display result to front and rear relative distance circuit has no effect on, because now comparator and simulation are opened Guan Jun is failure to actuate, and is not present like analog switch contact, front and rear relative in the simulative display effect such as Figure 24 of relative distance circuit Apart from shown in circuit 31a-31b.In order to which clear state is not drawn into analog switch from as far as nearly process of meeting, Figure 24 and accordingly connect Point.

The technique effect of generation described above, overcomes two cars in traveling of being met in 150 meters, receives and carry out the full of car And infrared signal, the constant disadvantage of luminous tube quantity that relative distance simulative display is lighted.

A kind of signal control display device (400), it is characterised in that have：

1), signal control device, by the forward and backward of voltage identificating circuit, signal control circuit, signal display circuit and periphery Demodulation change-over circuit composition is received, therebetween associated connection, the voltage signal for receiving control object is sorted through voltage discriminating Actuating station is reached from control passage afterwards, the sound and light signal for the corresponding driving states of fore-aft vehicle that meet is shown；And including relative distance Display control circuit, shows that interchange circuit and the forward and backward receiving demodulation circuit of periphery are constituted, association therebetween connects by relative distance Connect, met for two cars by as far as near, and two cars cross after relative distance simulative display from the near to the remote.

2) the signal display element of display mark is installed, for showing machine on, signal display control panel, control panel When motor-car meets, the direction position signalling of front and rear proximate vehicle, the relative distance simulative display signal of two car relative distances and phase Answer voice message signal；It is all to be arranged on control panel the signal display lamp of position and this car all around meet car up and down Physical location correspond.
