Abstract

The utility model relates to a vehicle antitheft controller for preventing drunken driving, which is provided with a DC regulated circuit, a detection circuit, a comparator and an actuator, wherein the detection circuit is composed of a wine-sensitive detector and a pneumatic cipher switch. The IC1 serves as the comparator and three 'coincidence gates' in the IC1 are connected one by one. The input terminals are connected respectively with the wine-sensitive detector, the pneumatic cipher switch and the vehicle igniting coil. The actuator is a relay 'K' which is used for controlling the make and break of the vehicle igniting switch. Only when the dual conditions are simultaneously available that the driver's mouth is without alcohol smell and the breathe cipher switch has no problem, the vehicle can be started and operated normally.

Description

Limiting driving after drinking, vehicle anti-theft controller

The utility model belongs to a kind of traffic safety facilities, is a kind of limiting driving after drinking effectively, vehicle anti-theft control setup.

The vehicle drunken driving is the major reason that causes traffic accident to take place, according to the incomplete statistics of traffic police department, because of the traffic accident that causes of drivining a car under the influence of alcohol accounts for 40% of traffic accident sum, its loss also is astonishing, in view of this, traffic law is clearly stipulated " Don't Drink and Drive " already.These administration means of the utilization that traffic police department also repeats injunctions are come limiting driving after drinking, though yet some navigating mates are had regulations to abide by, but remain incessant after repeated prohibition, often entertain the psychology that can not meet accident by sheer good luck, the lives and properties of putting individual and people are in ignoring, unexpectedly and conscious drunken driving vehicle still unconsciously, so traffic accident still takes place again and again, in order to reduce and stop the generation of traffic accident, avoid country, collective and individual's property to exempt from loss, means that must the utilization science guarantee the further practicable of administration means.

The purpose of this utility model is to be to provide a kind of limiting driving after drinking, vehicle anti-theft controller.

A kind of restriction is driven when intoxicated, the vehicle anti-theft controller, have direct current regulation circuit, sensing circuit, comparator and actuating unit etc., sensing circuit is made up of quick detector of wine and pneumatic cipher switch, and quick detector of wine and cipher switch are with being loaded in the shell of sensor the wine quick detector A utmost point and IC _1A1,2 pin link to each other, the output of pneumatic cipher switch then with IC _1B6 pin join.

Comparator is by IC ₁Deng composition, IC ₁Interior three " with door " link its IC step by step _1AInput 1,2 pin and W and the bleeder formed of the quick detector of wine link IC _1AExport 3 pin and IC _1B5 pin and V ₁Base stage join IC _1B6 pin and pneumatic cipher switch join IC _1BOutput 4 pin then with IC _1C8 pin join IC _1C9 pin pass through R ₃Open contact K with relay " K " _1-1An end and ignition lock Q ₂Go out end and R ₃An end link K _1-1The other end then link with the people of light-up plug end.IC _1COutput 10 pin and V ₂Base stage and diode VD ₁Negative pole join, to keep IC _1B6 pin be high level.

Actuating unit is relay " K ", its open contact K _1-1Be serially connected between automobile ignition switch and the light-up plug, promptly a termination ignition lock go out, another termination automobile spark plug people.

The utility model owing to adopted abovementioned technology, thereby is not only drunk and the password import could be driven by start a car when correct at chaufeur, thereby can be stopped safety traffic hidden danger and raising automobile burglar performance reliably.

Following accompanying drawing provides an embodiment of the present utility model;

Fig. 1 is the schematic diagram of limiting driving after drinking, vehicle anti-theft controller;

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

A kind of " limiting driving after drinking, vehicle anti-theft controller " is characterized in that it has direct current regulation circuit, sensing circuit, comparator and actuating unit; Wherein, sensing circuit is made up of quick detector of wine and pneumatic cipher switch etc., and comparator is served as by ic chip 1, ic chip ₁Three interior " with door " circuit are connected step by step, an input end of the mouth of last " with door " and back one " with door ", " with door " IC _1AInput end connect " with door " IC with the dividing potential drop branch road of forming by slide rheostat W and the quick detector of wine _1BAnother input end and pneumatic cipher switch join " with door " IC _1CAnother input end and automobile ignition coil join " with door " IC _1COutput join with magnet coil by aerotron V2 as the relay of actuating unit.When chaufeur goes out car, at first open total power switch Q ₁, at this moment storage battery is powered to automobile circuit, and gives the power supply of this controller with the time-division two-way, and wherein one the tunnel through the three-terminal voltage-stabilizing IC circuit ₂Be quick sensing circuit of wine and language alarm IC circuit ₃Stable+5V direct supply is provided, and another Lu Zejing W and alcohol sensor are IC _1A1,2 pin fixing dividing potential drop is provided, (tram, pneumatic cipher switch place) regulated W and should be made IC under near the situation of the no fume sensor _1A1,2 pin be always high level, IC so _1A Output 3 pin also for high level, be IC _1B5 pin also be high level, this moment aerotron V ₁End, the language alarm circuit is sounding not.

During start a car, navigating mate is opened ignition lock Q ₂, IC at this moment _1C9 pin obtain high level, alignment sensor is blown then, the number of times and the length of blowing, each car has different, and navigating mate can preset in advance voluntarily, be and establish password, for example: establish the long gas of mouthpiece and be " 1 ", mouthpiece is losed heart and is " 0 ", then password can be made as: 100,110,101,011,001,010 etc., blowing under the close errorless situation, then IC _1B6 pin become high level, that is to say that the first condition of start a car possesses, otherwise then do not possess, realized purpose with the antitheft car of cipher control.

When the navigating mate alignment sensor was blown, in fact whether sensor was drunk to navigating mate and is judged, under the situation of not drinking, and IC _1BSo 5 pin be high level IC _1BOutput 4 pin also for high level, be IC _1C8 pin be high level, then IC _1CInput 10 pin also be high level, so aerotron V ₂Conducting, relay " K " adhesive, its contact k _1-1The cut-in point ignition system, automobile can normally start.

After detecting navigating mate and drinking, IC then _1A1,2 pin become low level, IC _1AOutput 3 pin also be low level, relay " K " discharges, the truncation points ignition system, then automobile can not start.While V ₁Conducting, connect the language alarm circuit, send the verbal cue of " after drinking not Kai Che " continuously, therefore have only the air blowing password errorless, there is not fume again in the mouth simultaneously, under the situation that two conditions possess simultaneously, vehicle can normally start to travel, and this has just limited effectively drivings a car under the influence of alcohol and reach the purpose that prevents that vehicle is stolen.
