The interrelation and the principle of work of the utility model circuit part showed in Fig. 5～10, give by ignition lock by on-vehicle battery as shown in Figure 5 and amplify number power supply, make character display work by matrix circuit, and give interior battery charge and to other circuit supply by voltage stabilizer.The turning to of vehicle, meet an urgent need, speed-slackening signal discerned by signal recognition circuit, and make by driving circuit and to turn to the corresponding demonstration of display circuit.Meeting misfortune reports to the police and can be selected by two sets of plan: 1. directly touch binary pair by alarm switch, enter oscillating circuit work, make to turn to by actuator again to be shown as alarm condition; 2. programme by pole changer, its program enters oscillator by programming warning circuit shake-up binary pair, and driving circuit is after warning circuit work again, and delay counting circuit also starts thereupon, when predetermined time of fire alarming finishes, make the binary pair upset by relieving circuit, through finishing alarm condition.In case the effect of warning priority circuit is warning circuit work, then seal other signal line, to guarantee the warning circuit normal operation.Shown in Fig. 6,7: font, character, digital control circuit adopt many resistance R 1～R8 and many series-parallel modes of luminotron L1～L32 to constitute a display matrix circuit.According to after amplifying number required font, character, number and arranging in order, be connected in parallel and receive power end, this kind method is reliable, and every luminotron four point failure rates are reduced to 2 points (referring to influence the luminotron trouble point), and single font, character, digital electric current are reduced to minimum.Single font, character, digital back in parallel reliable operation.Report to the police shown in Fig. 7-8 turn to, brake, emergent display driver circuit by the TX-MOO1 circuit promptly three end power supplys 7896 provide, the driving tube of BG1-BG4 for showing, resistance R 1-R16, luminotron L1-L32 are formed the display circuit of reporting to the police, brake, turn to, meet an urgent need.

Referring to Fig. 9, brake to reporting to the police, turn to, the emergency control circuit principle elaborates:

When 1, static, by the rest-set flip-flop that IC1C, IC1D form, owing to IC1C pin 6 is in active potential, pin 5 is a high potential, so mouth pin 4 is a high potential.This current potential is acted on the oscillator of being made up of IC2C, IC2D by D5, D6, makes it be in nonoscillating state, and its mouth is output not, so the driving circuit of being made up of BG1-BG4 is not worked, does not have signal aspect and indication.

2, during Vehicular turn shown in Fig. 9,10 (turning to L is side), turn sign adds to IC1A pin 9 by D25, because its pin 8 is output as active potential, anti-phase by IC2A, export a high level and make actuator BG1, BG2 conducting, make corresponding L telltale show turn sign, principle identical (summary) when R turns to.

3, during car brakeing, speed-slackening signal shown in Fig. 9,10 is delivered to IC1A, IC1B pin 9, pin 13 by D27, D28, and actuator BG1-BG4 conducting simultaneously makes L, R telltale be shown as speed-slackening signal simultaneously.

When 4, vehicle is opened emergency light, see that Fig. 9,10:L, R telltale show simultaneously, be emergent demonstration, its principle is with above-mentioned, but anxious simultaneously latent the neglecting now of shows signal.

5, when needs are reported to the police, two kinds of schemes can be arranged, shown in Fig. 5,8,9:

1. utilize alarm switch K to report to the police, open K switch, IC1C pin 6 current potentials jump to high level by low level, this moment, so the binary pair upset, mouth pin 4 was a low level because its pin 5 also is a high level, so start working by the oscillator that IC2C, IC2D form, its output makes BG1-BG2, BG3-BG4 with per second frequency alternate conduction once, and its telltale is alternately flicker also, is alerting signal.

2. utilize pole changer to programme and report to the police, this circuit program is L-R-L, when needing to report to the police, earlier pole changer is put L and held that signal adds to IC3D pin 13 by D25, D15, because the effect of C6, this signal will keep a period of time.Again pole changer is put the R end this moment, signal is added to IC3D pin 12 by D28, D16, because remaining on the C6, a last signal do not disappear as yet, so the time IC3D be output as active potential, make IC3B mouth pin 4 be high potential, and hold it on the C5, put pole changer 1 end this moment again, and signal adds on the IC3A pin 2 through D25, D15, is high potential because C5 goes up, so the time IC3A mouth pin 3 be active potential, through the anti-phase high level that is output as of IC2F, add on the rest-set flip-flop K point, make the binary pair upset, 1. following circuit operation as stating, and reporting to the police begins.

6, alarm release, after the beginning of warning shown in Fig. 5,9, signal by oscillator output adds on the counting machine IC4 pin 10 by D3, thus each vibration swimming all count once towards IC4, up to reporting to the police time-delay (30) minute) after the end, make the BG5 conducting by IC4 pin 1 output high potential by D35, R4, make binary pair IC1C pin 5 be low level, the binary pair upset is output as high potential, oscillator quits work, and reports to the police and finishes.

7, shown in identification Fig. 8,9 of programming warning circuit: when L, R end adds signal respectively (as turning to), judge by C6, C5 charging duration, is common turn sign when the sigtnal interval between L-R during greater than 1.5S, less than 1.5S and occur continuously L-R-L more than three times signal be alerting signal.When signal (as braking, emergency light) appears in L, R end simultaneously, discern by IC3C, L, R signal add to IC3C pin 8,9 simultaneously by D25, D15, D28, D16 respectively at this moment, make it be output as low level, anti-phase through IC2E is high level, and this level makes IC3B pin 6 be always high level by D13, so IC3B mouth pin 4 high level can not occur, then high potential can not appear on the C5, so binary pair can not overturn.

8, power supply is supplied with and is added on the GND pin by D11 by on-vehicle battery, and its pin 1 is output as 6 volts of voltages of voltage stabilizing, and to amplification internal battery B charging, to this circuit supply.Thereby having guaranteed that in case the beginning of reporting to the police even cut off this amplification number all external on lines, this circuit also can Normal Alarm and guaranteed more than 30 minutes.

9, the preferential enforcement of warning, after warning circuit shown in Fig. 5,9 starts, binary pair IC1C pin 4 is output as low level, make IC1A pin 8, IC1B pin 12 be low level, this moment, no matter L, R brought out existing what signal, can be by the warning priority circuit of forming by IC1A, IC1B, thus guarantee the warning circuit normal operation.

10, the above-mentioned element purposes that do not relate to is among Fig. 9: C1, C2 are vibration time-frequency electric capacity.Form the RC oscillator, and determine its oscillation frequency with R1, R2, IC2C, IC2D.C3 slowly raises AIC1C pin 5 current potentials, thereby guarantees that IC1C is output as high potential, thereby avoid the warning circuit false triggering for when the moment of energized.R5, R6, R7, R18 are provided a high potential by it connects pin, R8, R9, R10, R11, R13, R14, R15, R16 constant resistance are divider resistance, form bleeder by it, make signal voltages such as L, R, C can not be higher than the IC power line voltage, R12, R17 are discharging resistance, after the triggering of reporting to the police, it is bled off the last electric charge of C5, C6, so that next warning function is normal.2CW1 is a stabilivolt, and it makes the GND output voltage be always 6 volts, in case GND overtension and make over-charging of battery, 2CW2,2CW3,2CW4 act as and make its corresponding IC input end import an on-off signal, thereby avoids the input of linear signal and cause circuit erroneous action.D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14, D15, D16 are isolation diode, in order to prevent interacting between each element circuit.C4 is a filter capacitor.
