Abstract
Provided is a control system circuit for proofing drunk driving, including a power supply device, and a single-chip microcomputer, a voice alarm module, a braking module, a display module, and an alcohol concentration acquisition module which are connected with the power supply device. The alcohol concentration acquisition module includes an alcohol sensor, a comparator, an amplifier, and an A/D converter, the display module includes an LED nixie tube and an LED decoder, the voice alarm module includes a voice chip and a DC/DC power supply converter, the braking module controls oil-way supply via a relay, the voice alarm module and the display module are arranged in a cab, the voice alarm module reminds a driver that the alcohol concentration is too high for driving, and the display module displays the present alcohol concentration via the LED nixie tube. The control system circuit provided can detect whether a driver is over the drink drive limit, the driver breathes into the sensor, the alcohol concentration in the driver's blood can be displayed on a device; meanwhile, the control system circuit provided can perform autonomous determination according to whether the detected alcohol concentration exceeds the drink drive limit to control the power supply circuit of the ignition device of an automobile so that a driver who has been drinking cannot start the automobile.
Description
Technical field
The utility model relates to the safe recognition system field, particularly a kind of control system circuit that prevents that chaufeur from driving when intoxicated that a kind of chaufeur of in-vehicle is driven.
Background technology
The life security problem is the problem that the mankind show great attention to always.The factor that the human life is threatened safely has a lot, and wherein, drunken driving is exactly a very important deterrent.Drive when intoxicated and cause traffic accident countless, bring significant damage.According to statistics, in the traffic accident that the whole nation takes place, 50% ~ the ~ 60%, cause that by driving when intoxicated the probability that has an accident of driving when intoxicated is up to 27%.Along with the increase of taking in the alcohol amount, select the reaction error rate significantly to increase, alcohol content has 0.5 ‰ to increase to 1 ‰ in blood, just the possibility that gets into an accident increases by 500, if increase to 1.5 ‰, possibility increases by 6 times again.Drive when intoxicated the traffic accident that causes to country, other people, oneself produced the consequence that is difficult to estimate.How solving of the problem of driving when intoxicated, each country is striving to find way.
The utility model content
For overcoming the above problems, the utility model discloses a kind of control system circuit that prevents that chaufeur from driving when intoxicated, can detect chaufeur and whether drink and exceed standard, make drinking drive person can't start automobile.
A kind of control system circuit that prevents that chaufeur from driving when intoxicated comprises supply unit, micro controller system, audio alert module, brake module, display module and alcohol concentration acquisition module; Described supply unit is connected with described brake module with described micro controller system, described audio alert, described alcohol concentration acquisition module, described display module respectively; Described alcohol concentration acquisition module comprises alcohol sensor, comparator, amplifier and A/D converter, and described display module comprises LED charactron and LED decoder; Described audio alert module comprises speech chip and the conversion of DC/DC power supply; Described brake module is mainly supplied with by relay control oil circuit, described audio alert module and display module are installed in operator's compartment inside, too high should not the driving of audio alert module prompting chaufeur alcohol concentration, display module shows current alcohol concentration by the LED charactron;
Described alcohol concentration acquisition module detects the alcohol gas concentration signal by described alcohol concentration sensor, and described alcohol concentration sensor adopts semi-conductor type MQ-3 alcohol sensor or fuel cell type alcohol sensor; And detected signal is sent in amplifier and the comparator, through amplification with relatively, again signal is sent into A/D converter with analog signal, be converted into digital signal, the digital signal that produces is passed to micro controller system, and micro controller system sends different instructions according to the letter difference of importing into.
Described brake module electromagnetic relay of circuit series connection between ignition lock and primary ignition coil, and open close by the external aerotron control relay of single-chip processor i/o mouth, and the open and close controlling firing circuit by relay contact.
Whether the utility model compared with prior art has the following advantages: that adopts a kind of in-vehicle has that alcoholic strength detects and the electric-control system of safety control function, can detect chaufeur and drink and exceed standard.Chaufeur is as long as blow mouth facing to sensor, just can demonstrate the height of chaufeur blood alcohol concentration on the instrument, simultaneously whether exceed standard and independently judge according to detecting alcohol concentration, can control the automobile igniter power circuit, make drinking drive person can't start automobile.
