Among the figure, alcohol sensor output and coded lock part that probe and asepwirator pump are formed act on switch circuit, control ignition coil and lock more respectively.Wherein, probe and blower pump are exactly (A) part among Fig. 1, and keyboard 2 is (C) part among Fig. 1.

In Fig. 3, JM is a QM-J1 type ethanol-sensing component (pipe), and it is that metal oxide semiconductor material is made " fume-" conversion element.When the constant current source of being made up of resistance R 16 and aerotron BG5 provides electric current about 140MA for filament C-C ', with A-A ', the preheating of the B-B ' utmost point, in the air of cleaning, two interpolars (A-A ', B-B ') resistance is bigger, and its mouth B-B ' utmost point above earth potential is lower, the output of ethanol-sensing component no signal.When having alcohol gas to touch the JM ethanol-sensing component in the air, on the ethanol-sensing component surface immediately chemiadsorption can take place, B-B ' utmost point above earth potential is risen, the size of its value is directly proportional with alcohol gas concentration in the detected air, ethanol-sensing component is with regard to the signal output of generation " fume-" like this, one the tunnel delivers to next stage aerotron (BG6), makes light-emitting diode (D7) conducting send light.(R6, BG8 BG9) make relay (J2) action, make contact release, and the power supply of halt point fire coil reaches the purpose of locking car through the resistance aerotron on another road.

At Fig. 4, among Fig. 5, the Puzzle electronic lock circuit is by a slice CD4017 decade counter/distributing box and one six Schmidt trigger CD40106 and resistance thereof, electric capacity is formed (being equal to the part 3 among Fig. 2), utilize the numerical ciphers of the last various combination of keyboard S0～S9, high level appears in mouth Q0～Q7 at decade counter/distributing box successively, and input to the CP input end through the two poles of the earth shaping with the form of pulse, high level appears until Q8, through the two poles of the earth Schmidt, R7 to BG1 base stage, make the BG1 conducting, with relay J 1 adhesive, and lean on the open contact (J1-1) of relay itself that relay is pinned, simultaneously, another is the auxiliary circuit power supply of the quick pipe of wine (sensor) to contact (J1-2) adhesive.The bright expression of D9 is correct by the numerical ciphers of keyboard input.

Alcohol sensor is to provide electric current about about 140MA by the constant current source that BG5 constitutes, adjust the background voltage of the quick tube sensor of wine by potential device W, background voltage is promptly when in the air during alcohol-free gas, the output voltage of the quick pipe of wine, when alcohol gas, the voltage of the quick pipe of wine is added background voltage, as the output voltage of alcohol sensor.When sensitivity arrives alcohol gas, the quick pipe B-B ' of wine utmost point above earth potential raises, and the emitter current potential of emitter follower BG6 is raise (BG6 conducting), makes the BG7 conducting, and making the light-emitting diode D7 that is connected in the collector circuit shinny, expression driver (or chaufeur) drinks.Anti-phase by aerotron BG8 simultaneously, aerotron BG9 is ended, turn-off relay J 2, i.e. the power supply of cutting off machine motor-car (automobile) high-tension coil, thus self-propelled vehicle (automobile) can't be travelled.Otherwise if the driver does not drink, then BG6 emitter current potential very low (BG6 ends) ends BG7, thereby diode D7 is not worked, and the power supply of self-propelled vehicle (automobile) high-tension coil is connected in relay J 2 adhesives, thereby automobile can normally start to travel.

Among the figure, relay J 1 is equivalent to the relay 4 among Fig. 2, the quick pipe JM of wine be among Fig. 2 the probe and asepwirator pump in the quick pipe of wine, the switch circuit 5 among Fig. 2 is the BG6～BG9 among Fig. 5, relay J 2 is the relay 6 among Fig. 2.The bright expression alcohol sensor of D5 work worker is normal.

The asepwirator pump control circuit is delivered to RC, charging and LM555 time base circuit, and the control asepwirator pump, from beginning about 15 minutes work-hours, after this asepwirator pump (PM) shuts down.Alcohol sensor relies on the diffusion of gas to come responsive (monitoring) alcohol gas later on, has so just reduced the passenger and has drunk (or other factors), to the influence of alcohol prohibition device (alcohol sensor).

Because the utility model is that the antitheft and alcohol gas of electronic cipher monitoring two big functions are arranged, so can prevent driver or automobile driver the driving a car under the influence of alcohol traffic accident that causes and the generation of traffic accident effectively.In addition, connecting mode adopts the cable-to-cable connector mode in the utility model, is unfamiliar with the stealer of machine performance, the car of can't setting about to steal.The electronic cipher that is adopted as remember telephone number easily, convenient, also seem to use as the telephone number and use easily.Button input, and electronic cipher conversion have arbitrarily so just improved confidentiality greatly.Do not know that as stealer password or mistake access to your password, and start a car by force can not start not only, and can also sound, light reports to the police simultaneously, attract much attention.Driver or chaufeur not only can not start automobile after drinking, and in a single day pop one's head in running car (alcohol sensor) sucks alcoholic air, automobile also can be because of flame-out (ignition circuit blocks) stop off, and loudspeaker pipe, cause traffic police's attention, when having only the probe impression less than spirituosity gas, automobile ability cruising so just can prevent the problem that the driver drivings a car under the influence of alcohol or drinks midway effectively.The utility model is applicable to various self-propelled vehiclees, as autotruck, carryall, utility van, little sleeping carriage, motor bike, trac. or the like.The utility model can also be used for alcohol gas monitoring, warning and theft-proof place.
