Abstract
Disclosed is a novel control system circuit for preventing drunk driving of a driver. The novel control system circuit comprises a power source device, a single-chip microcomputer, a voice alarming module, a braking module, a display module and an alcohol concentration collecting module, wherein the single-chip microcomputer, the voice alarming module, the braking module, the display module and the alcohol concentration collecting module are connected with the power device. The alcohol concentration collecting module comprises an alcohol sensor, a comparator, an amplifier and an A/D (analog/digital) converter. The display module comprises an LED nixie tube and an LED decoder. The voice alarming module comprises a voice chip and a DC/DC (direct current) power source converter. The oilway supply of the braking module is mainly controlled by a relay, both the voice alarming module and the display module are installed in a driving cab, the voice alarming module prompts the driver of overhigh alcohol concentration which is not suitable for driving, and the display module displays current alcohol concentration by the LED nixie tube. The novel control system can detect whether the alcohol concentration of the driver exceeds standards or not, the driver can blow the sensor, and the instrument can display the alcohol concentration in blood of the driver. Meanwhile, the novel control system can automatically judge to control a power source circuit of a vehicle ignition device and enable the drunk driver not to start the vehicle according to whether the alcohol concentration exceeds the standards or not.
Description
Technical field
The present invention relates to safe recognition system field, particularly a kind of new control system circuit that prevents that chaufeur from driving when intoxicated that a kind of chaufeur of in-vehicle is driven.
Background technology
Life security problem is the problem that the mankind show great attention to always.What human life was threatened safely is a lot of because have, 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 occurs, 50% ~ the ~ 60%, cause by driving when intoxicated, the probability that has an accident of driving when intoxicated is up to 27%.Along with taking in the increase of alcohol amount, select reaction error rate significantly to increase, when alcohol content in blood has 0.5 ‰ to increase to 1 ‰, just the possibility getting 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 and be difficult to the consequence estimated.How solving of Question of Driving After Drinking, each country is striving to find way.
Summary of the invention
For overcoming the above problems, the invention discloses a kind of new control system circuit that prevents that chaufeur from driving when intoxicated, can detect chaufeur and whether drink and exceed standard, make drinking drive person cannot start automobile.
Prevent the new control system circuit that chaufeur is driven when intoxicated, comprise supply unit, micro controller system, audio alert, brake module, display module and alcohol concentration collection; Described supply unit is connected with described brake module with described micro controller system, described audio alert, described alcohol concentration collection, described aobvious module respectively; Described alcohol 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 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 LED charactron;
Described alcohol concentration acquisition module detects 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 the signal detecting is sent in amplifier and comparator, through amplification with relatively, then signal is sent into A/D converter by analog signal, be converted into digital signal, the digital signal of generation is passed to micro controller system, and micro controller system, according to the letter difference of importing into, sends different instructions.
The described brake module electromagnetic relay of connecting on the circuit between ignition lock and primary ignition coil, and open close by the external aerotron control relay of single-chip processor i/o mouth, and by the open and close controlling firing circuit of relay contact.
Whether the present invention compared with prior art has the following advantages: adopt a kind of alcoholic strength that has of in-vehicle to detect 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, on instrument, just can demonstrate the height of chaufeur blood alcohol concentration, independently judge according to detecting whether alcohol concentration exceeds standard simultaneously, can control automobile igniter power circuit, make drinking drive person cannot start automobile.
