Abstract
The utility model discloses a 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, wherein 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 light-emitting diode (LED) 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, the 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, by mean of the safety identification system for automobile driver drunk driving, and therefore the driver who drinks cannot start an automobile.
Description
Technical field
The utility model relates to the 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
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 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 the increase of taking in the alcohol amount, select the reaction error rate significantly to increase, when alcohol content in blood has 0.5 ‰ to increase to 1 ‰, 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 Question of Driving After Drinking, each country is striving to find way.
The utility model content
For overcoming the above problems, the utility model discloses the safe recognition system that a kind of automobile driver of the utility model is driven when intoxicated, make drinking drive person can't start automobile.
The safe recognition system that a kind of automobile driver of the utility model is driven when intoxicated comprises micro controller system, the audio alert module that is connected with micro controller system, draws machine control module, alcohol concentration acquisition module and LCD MODULE; The alcohol concentration acquisition module mainly detects the alcohol gas concentration signal by alcohol concentration sensor; LCD MODULE mainly shows current alcohol concentration by LED 7 segment numeral pipes; The audio alert module is mainly sent information of voice prompt by buzzer phone; Drawing the machine control module is mainly supplied with by the Control oil circuit;
Described alcohol concentration sensor adopts semi-conductor type MQ-3 alcohol sensor or fuel cell type alcohol sensor; And the signal that detects is sent in amplifier and comparator, through amplification with relatively, then signal is sent into A/D converter with analog signal, digital signal in transforming, the digital signal that produces is passed to micro controller system, and micro controller system is different according to the letter that imports into, makes 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 the open and close controlling firing circuit by relay contact.
Whether the utility model 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, just can demonstrate the height of chaufeur blood alcohol concentration on instrument, simultaneously whether exceed standard and independently judge according to alcohol concentration being detected, can control the automobile igniter power circuit, make drinking drive person can't start automobile.
Description of drawings
Accompanying drawing is a kind of the utility model structural representation.
The specific embodiment
As shown in drawings, the safe recognition system that a kind of automobile driver of the utility model is driven when intoxicated comprises processor of single chip computer, audio alert module, draws the machine control module, LCD MODULE and alcohol concentration acquisition module; The alcohol concentration acquisition module mainly detects the alcohol gas concentration signal by alcohol concentration sensor; LCD MODULE mainly shows current alcohol concentration by LED 7 segment numeral pipes; The audio alert module is mainly sent information of voice prompt by buzzer phone; Drawing the machine control module is mainly supplied with by the Control oil circuit;
Further, the safe recognition system that described a kind of automobile driver is driven when intoxicated, described alcohol concentration acquisition module is mainly to detect the 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 that detects is sent in amplifier and comparator, through amplification with relatively, then signal is sent into A/D converter with analog signal, digital signal in transforming, the digital signal that produces is passed to micro controller system, and micro controller system is different according to the letter that imports into, makes different reactions.
Further, the 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 the open close of the external aerotron control relay of single-chip processor i/o mouth arranged, and pass through the open and close controlling firing circuit of relay contact.
The above; only embodiment of the present utility model; be not that the utility model is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technical spirit changes, and all still belongs in the protection domain of technical solutions of the utility model.
