Description of drawings

Accompanying drawing 1 is the drunken driving reminiscences circuit catenation principle figure that the utility model provides.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1, a kind of drunken driving reminiscences is characterized in that: comprise that power circuit, fume pick up amplifying circuit, high tension ignition control circuit and phonetic warning circuit etc.Described power circuit comprises storage battery, integrated package of pressure-stabilizing and filter capacitor; Described fume picks up amplifying circuit and comprises alcohol gas sensitive device, resistor, adjustable potentiometer and sampling amplifying triode; Described high tension ignition control circuit comprises integrated circuit block IC2, IC3 and peripheral resistor; Described phonetic warning circuit comprises integrated package, aerotron and the loud speaker of being with speech chip.The voltage stabilizing out-put supply picks up amplifying circuit, high tension ignition control circuit and phonetic warning circuit with fume respectively and is connected.

In the accompanying drawing 1, VT1, VT3 are C9013 type aerotron, and VT2 is a C9012 type aerotron; R1-R4 is the JR-1/2W metal film resistor; RP1-RP2 is the organic solid adjustable potentiometer of WSW type; C1-C2 is a CD11-16V type aluminium electrolutic capacitor; IC2 is TWH8778; B is 8 Ω, 0.25W dynamic loud speaker; K is a key switch on the car; T is original igniting high voltage package on the car; QM is a QM-NJ9 type alcohol smell detection gas sensor, and during pure air, resistance value is up to 60K Ω between YX, and when air spirituosity concentration reached 100ppm, resistance dropped to 6.5K Ω between YX, and it is K=9.5 to the alcohol smell detection sensitivity coefficient, and anti-other gas interference performance is strong.

Principle of work: the utility model drunken driving reminiscences, its power supply, are used for fume pick-up circuit, control circuit and warning circuit through three terminal regulator LM7805 voltage stabilizing output+5V vdc by the 12V storage battery.When chaufeur was not drunk wine preparation driving, be 60K Ω high value between the X-Y of alcohol detection gas sensor QM, the electric current of RP2 of flowing through is just very little, the VT1 base stage is in active potential, VT1 is in high potential by collecting electrode, + 5V power supply charges to C2 through R2, the last voltage of C2 raises gradually, after several seconds, be that switch ic chip 2 pin 5 voltages reach cut-in voltage 1.6V, pin 2 output+5V high level are on the one hand made the control voltages for switch integrated circuit piece IC3 pin 2, make the pin 3 of IC3 integrated package, pin 5 conductings, storage battery 12V voltage is through the pin 3 of ic chip 3, pin 5 and key switch K can start isolating high-pressure ignitor T igniting makes engine operation, and this car can normally start; On the other hand, VT2 transistor base voltage and emitter voltage all be+and 5V equates that VT2 ends, and the phonetic warning circuit can not send voice suggestion and represent that vehicle can start to travel yet.When chaufeur was drunk a certain amount of wine and was prepared steering vehicle, when the air alcohol concentration reaches 100mmp near the QM probe, change several kilo-ohms low resistance between the gas sensitive device X-Y into, the electric current of RP2 of flowing through this moment is bigger, the VT1 base stage is in high potential, its collecting electrode of VT1 conducting becomes active potential, be that switch ic chip 2 pin 5 current potentials are always low level, switch ic chip 2 inside are closed, pin 1,2 open circuits of pin, be the pin 2 no-output voltages of switch integrated package TWH8778, IC3 pin 2 no input control voltages then make the pin 3 of ignition circuit switch ic chip 3, pin 5 open circuits, key switch K closure also no current flows through high-tension coil T, driving engine can not ignition operation, and vehicle can not start; Meanwhile, the conducting of positive-negative-positive VT2 aerotron forward bias, the pin 8 of IC4 phonetic warning integrated package KD9561 has+the 5V operating voltage, built-in voice chip start working, phonetic warning device B sends the caution voice of " driver's wine-drinking can not be driven ", further stops the driver to drive to move ahead.Aerotron VT3 plays amplification to voice signal and drives speaker operation; IC3 integrated package inside has big electric current to pass through, and must be fixed on the heating panel and dispel the heat; The adjustment of RP1 and RP2 potential device can change the sensitivity that the drunken driving reminiscences detects fume.

The body of drunken driving reminiscences is made up of two parts, the one, the printed panel of the above-mentioned components and parts of welding, the area size is 50mm * 40mm, another part is the plastic casing that installs and fixes printed panel, area is 55mm * 55mm, the shell centre open a radius be the 10mm osculum as QM-NJ9 type alcohol smell detection gas sensor window, open a φ 3mm self-tapping screw hole respectively at 22mm place, window central authorities both sides and make drunken driving reminiscences single-piece fixation.

Though described embodiment of the present utility model in conjunction with the accompanying drawings, the protection domain that those of ordinary skills do not need various distortion that creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
