Abstract
The invention discloses a novel safety identification system for automobile driver drunk driving. The safety identification system for the automobile driver drunk driving is characterized by comprising a single-chip microcomputer, a voice alarm module, an engine control module, an alcohol concentration collection module and a liquid crystal display module,; the voice alarm module, the engine control module, the alcohol concentration collection module and the liquid crystal display module are connected with the single-chip microcomputer; the alcohol concentration collection module is used for detecting alcohol gas concentration signals mainly through an alcohol concentration sensor. The liquid crystal display module is used for displaying the current alcohol concentration mainly through a LED (Light Emitting Diode) 7-section digital nixie tube; the voice alarm module is used for sending out voice prompt information mainly through a buzzer; the engine control module controls oil path supply mainly through a relay; the safety identification system can detect whether a driver drinks excessively. The driver only needs to blow towards the sensor with the mouth, an instrument can display the alcohol concentration in blood of the driver, meanwhile automatic judgment can be conducted according to the detected alcohol concentration, an automobile ignition device power circuit can be controlled, and therefore the driver who drinks cannot start an automobile.
Description
Technical field
The present invention relates to the new type of safe recognition system of driving when intoxicated in safe recognition system field, particularly a kind of automobile driver that a kind of chaufeur of in-vehicle drives.
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 the new type of safe recognition system that a kind of automobile driver of the present invention is driven when intoxicated, make drinking drive person cannot start automobile.
The new type of safe recognition system that a kind of automobile driver of the present invention is driven when intoxicated, comprises micro controller system, the audio alert module that is connected, draws machine control module, alcohol concentration acquisition module and LCD MODULE with micro controller system; Alcohol concentration acquisition module mainly detects alcohol gas concentration signal by alcohol concentration sensor; LCD MODULE mainly shows current alcohol concentration by LED 7 segment numeral pipes; Audio alert module is mainly sent information of voice prompt by buzzer phone; Drawing machine control module is mainly supplied with by Control oil circuit;
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, digital signal in transforming, the digital signal of generation is passed to micro controller system, and micro controller system, according to the letter difference of importing into, is made different reactions.
The described machine control module electromagnetic relay of connecting on the circuit between ignition lock and primary ignition coil that draws, 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: 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.
Accompanying drawing explanation
Accompanying drawing is a kind of structural representation of the present invention.
The specific embodiment
As shown in drawings, the new type of safe recognition system that a kind of automobile driver of the present invention is driven when intoxicated, comprises processor of single chip computer, audio alert module, draws machine control module, LCD MODULE and alcohol concentration acquisition module; Alcohol concentration acquisition module mainly detects alcohol gas concentration signal by alcohol concentration sensor; LCD MODULE mainly shows current alcohol concentration by LED 7 segment numeral pipes; Audio alert module is mainly sent information of voice prompt by buzzer phone; Drawing machine control module is mainly supplied with by Control oil circuit;
Further, the new type of safe recognition system that described a kind of automobile driver is driven when intoxicated, described alcohol concentration acquisition module is mainly to detect alcohol gas concentration signal by described alcohol concentration sensor, described alcohol concentration sensor is preferentially selected semi-conductor type MQ-3 alcohol sensor, also can select 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, digital signal in transforming, the digital signal of generation is passed to micro controller system, and micro controller system, according to the letter difference of importing into, is made different reactions.
Further, the new type of safe recognition system that described a kind of automobile driver is driven when intoxicated, the described machine control module electromagnetic relay of connecting on the circuit between ignition lock and primary ignition coil that draws, and there be the open close of the external aerotron control relay of single-chip processor i/o mouth, and by the open and close controlling firing circuit of relay contact.
The above; only embodiments of the invention; not the present invention is imposed any restrictions, every any simple modification of above embodiment being done according to the technology of the present invention essence, change and equivalent structure change, and all still belong in the protection domain of technical solution of the present invention.
