Description
Technical field
The present invention relates to Driving Skills field, specially a kind of intelligent drunk-driving prevention control system.
Background technique
The accident investigation of the World Health Organization shows, about 50% -60% traffic accident with drive when intoxicated it is related, after drinking
Driving has been listed in the main reason for traffic accident is lethal.Every year since the traffic accident for initiation of driving when intoxicated reaches tens of thousands of；And it makes
At in dead accident 50% or more all with drive when intoxicated it is related.The stimulation of alcohol makes one excited when drinking, unconsciously
It can drink more, when alcohol reaches a certain concentration in blood of human body, people will decline extraneous respond and control ability,
The ability of processing emergency also declines therewith.For drunken driving, alcohol content in blood is higher, collides
Probability it is bigger.When driver's alcohol content in blood reach 80mg/100mL when, occur traffic accident probability be in blood not
2.5 times when spirituosity；When reaching 100mg/100mL, occur traffic accident probability be in blood not spirituosity when 4.7
Times.Even if the danger level of traffic accident also can reach 2 times or so of state of not drinking in the state of low alcohol consumption.
Lack a kind of control system for preventing drunk driving in existing automobile, prompting and anti-driving cannot be played to driver
Effect, since individual drinking drive persons are with idea of leaving things to chance, continue to drive, security performance is caused to be difficult to ensure.

Detailed description of the invention
Fig. 1 is a kind of intelligent drunk-driving prevention control system block diagram of the present invention；
Fig. 2 is a kind of intelligent drunk-driving prevention control system flow chart of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2: a kind of intelligence drunk-driving prevention control system, including single-chip microcontroller,
The single-chip microcontroller is electrically connected with igniter and connects relay, door contact interrupter, key switch, alcohol signal switch, warning output
Relay, manual switch, seat switch, image sensor and belt force sensor, the igniter connect relay
Device is electrically connected with firing key, and the warning output relay is electrically connected with buzzer switch and alarm, the buzzing
Device switch is electrically connected with buzzer, and the manual switch is electrically connected with alcohol content tester, and the seat switch is electrically connected
There is camera, the camera is electrically connected at single-chip microcontroller.
Specifically, the single-chip microcontroller includes facial comparison, the time relay, is automatically deleted module and re-types module.
Specifically, the alcohol content tester includes insufflation pressure sensor, the insufflation pressure sensor is electrically connected at
Single-chip microcontroller.
Specifically, the model KM3 alarm of the alarm.
Specifically, the time of the time relay design is no more than 20min.
Specifically, the alarm content of the buzzer is to forbid drunk driving, the alarm content of the alarm is that please fasten peace
Full band.
Specifically, it is microcomputerized controller that the single-chip microcontroller, which uses, by microprocessor, memory, input/output interface,
Analog-digital converter and the large scale integrated circuit composition of shaping, driving.
Specifically, the image sensor, belt force sensor and insufflation pressure sensor are gauge pressure formula
Pressure sensor.
In conclusion the present invention opens car door closed door into the car, door contact interrupter closure by driver.Work as driving
When people is seated on the seat, after pressure sensor measures pressure, seat switch closure.Keep to the side in front of driver it is upper installation one take the photograph
As head, the entire drunk driving test process of driver is monitored, extracts the facial characteristics of driver, and in process of entirely driving
In preserve always, prevent from practising fraud.Key switch is opened, when pressing manual switch, pops up alcohol content tester.When driver's sheet
People blows, and when detecting that alcohol content is not exceeded, alcohol signal is closed the switch.As long as connecting firing key point at this time
Fire, automobile can start.If alcohol content is exceeded, alcohol signal switch is disconnected, and engine can not start.Single-chip microcontroller will be controlled
Buzzer switch closure processed, buzzer warning " forbid drunk driving ".After detection, alcohol content tester rebounds automatically.In addition to this,
Other the interior interference of passenger to test result of drinking, system also use pressure sensor, are only centainly blowing in order to prevent
Under pressure effect, alcohol content tester just starts to detect.
When driver does not fasten seat belts, when pulling force is not detected in the tension sensor being mounted on safety belt, can also
Start KM3 alarm by controller, alarms " Buckle Up ".
In automobile whole driving process, automobile can extract facial characteristics and the detected person of driver person incessantly
Face is compared.If comparing consistent, automobile normal running.If comparison is inconsistent, single-chip microcontroller will control buzzer hair
Alarm " forbidding drunk driving " out, until driver's flame-out parking.
In addition to this, flame-out after 20 minutes, the Facial Features of detected person can be automatically deleted.If when flame-out
Between within 20 minutes (it is interim busy on the way in driving for driver, need to get off one it is small can the case where), then he is next
It, only need to be towards camera, if the system detects that the facial characteristics of the driver and the driver remembered recently when starting automobile
Facial characteristics be consistent, then driver need to only open keyed ignition, automobile can start.If not being consistent, need to re-start
Alcohol detection.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
