Description
Technical field
The utility model belongs to automotive safety and traffic safety technology field, particularly a kind of anti-safety device of driving when intoxicated.
Background technology
According to regulation in " vehicular drive personnel blood, breath alcohol concentration threshold value and check " (GB19522-2004) of the issue of national quality supervision and inspection Quarantine Bureau, this regulation is pointed out, driver from drunk driving refers to that the alcohol content in vehicular drive personnel blood is greater than or equal to 20mg/100ml, less than the driving behavior of 80mg/100ml.The accident investigation demonstration of the World Health Organigation in 2008, about 50%-60% traffic accident is relevant with drunken driving, and drunken driving has been listed in the lethal major cause of traffic accident.Along with increasing of private car, the harm of driving when intoxicated is startling, has become first " killer " of traffic accident.The 16 meeting of 11 Standing Committee of the National People's Congress of China will be reviewed criminal law amendment (eight) draft, drink-driving or sentenced first.The seriousness of this fully shows driving when intoxicated.Therefore, good, the anti-drunk driving safety system that cost is low of a kind of practicality of invention has necessity and urgency.The application is by take the MCS-51 series monolithic as control core, and coordinates alcohol concentration sensor MQ-3, realizes preventing the behavior that chaufeur is driven when intoxicated, and then reduces the traffic accident that causes because driving when intoxicated.
Summary of the invention
The purpose of this utility model is, a kind of anti-safety device of driving when intoxicated is provided.This device by alcohol concentration sensor is arranged on chaufeur breathe over against the place, automatically detect the alcohol concentration in the chaufeur body, then compare with the alcohol concentration of setting, if surpass setting value, just can cut off by the actuating of relay loop of ignition lock, make automobile not start, and can send sound and light alarm, reminding driver.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of anti-safety device of driving when intoxicated comprises alcohol concentration detecting unit, information process unit, auto Not Permitted start unit, acousto-optic warning unit.Wherein the mouth of alcohol concentration detecting unit is connected with the information process unit input end, and the information process unit mouth is connected with acousto-optic warning unit with forbidding the vehicle launch unit respectively.
The anti-safety device of driving when intoxicated of the present utility model is suitable for most automobile, can be used for private car and also can be used for city motor bus etc.This system can reduce the possibility of driving when intoxicated and setting out on a journey, and is conducive to safety traffic, protection people's life safety and property safety.Have easy to make, the characteristics such as circuit is simple, and cost is low, and circuit safety is good, and speed of response is quick.

Below in conjunction with the drawings and specific embodiments, particular content of the present utility model is described further.
The specific embodiment
With reference to Fig. 1, a kind of anti-safety device of driving when intoxicated comprises alcohol concentration detecting unit, information process unit, forbids vehicle launch unit and acousto-optic warning unit.Power on the start after, at first system carries out initialization, then the alcohol concentration detecting unit is started working, and the alcohol concentration signal that obtains is processed then result to be input in micro controller system by ADC0809 process, and changes the analog quantity of alcohol concentration into digital signal.Then the digital quantity of gained and the alcohol concentration value of setting are compared, judge whether to belong to drunken driving.If judge that chaufeur is to drive when intoxicated, relay disconnects the loop of ignition lock, and automobile can't be started, and sound and light alarm can reminding driver simultaneously.
With reference to Fig. 2, be information process unit of the present utility model shown in figure, use be the STC89C52 of STC Corporation, the utility model adopts the STC89C52 micro controller system of MCS-51 series, because the STC89C52 micro controller system is widely used, and stable performance, antijamming capability is strong, and cost performance is high.STC89C52 has comprised 8 bit CPUs, sheet internal oscillator, 8K bytes Flash, 512 byte RAM, 2 16 bit timing devices, counting machine, interrupt structure, I/O interface etc.The digital signal that ADC0809 can be converted is processed comparison, then the work of the action of control relay and acousto-optic warning unit.
With reference to Fig. 3, be that alcohol concentration of the present utility model detects detecting unit shown in figure, be the sensor unit of this system.The MQ-3 gas sensor has very high sensitivity and good selectivity to alcohol vapour, can export analog quantity 0 ~ 5V voltage, and concentration more high potential is higher.And have long-term service life and failure-free stability, and fast speed response recovery characteristics is arranged.In the time of installation, with the admission port of this sensor expiration direction over against chaufeur, can be fixed on steering handwheel.China's regulation, driver from drunk driving refers to that the alcohol content in vehicular drive personnel blood is greater than or equal to 20mg/100ml, less than the driving behavior of 80mg/100ml.Consider error, so the alcohol limit value of default is 15mg/100ml, before using, first use the alcohol vapour calibrating sensors of 200ppm to calibrate, and also will carry out necessary compensation to temperature drift.
It is that analog output interface circuit AOUT is connected with the IN0 of ADC08009 that circuit connects.
With reference to Fig. 4, vehicle launch and the acousto-optic warning unit forbidden of the present utility model shown in figure can according to the signal of information process unit, be controlled the break-make in automobile loop, and whether send sound and light alarm.When the base stage of aerotron is high level, the cut-off of PNP aerotron, relay is not worked, the relay normally closed contact is always closed, and the loop of automobile igniting circuit is connected, and can start automobile by ignition lock, simultaneously, the LED lamp of acousto-optic warning unit and buzzer phone are opened circuit; When the base stage of aerotron is low level, the conducting of PNP aerotron, relay work, the relay normally closed contact disconnects, and open contact is closed, relay is by adhesive, the loop of automobile igniting circuit is disconnected, and can not start automobile by ignition lock, simultaneously, LED lamp and the buzzer phone of acousto-optic warning unit are switched on, and reminding driver can not driver from drunk driving.
With reference to Fig. 5, be workflow of the present utility model in figure.
