Description
Technical field
The utility model relates to a kind of vehicle-mounted alcohol testing system, is specifically related to the comprehensive alcohol detection system of a kind of vehicle-mounted multisensor based on fuzzy reasoning principle.
Background technology
Society economy develops rapidly, the raising of whole society personnel quality of life thereupon, automobile becomes people's go off daily already and to ride instead of walk requisite instrument, the significant problem that the increase of automobile quantity also allows road traffic safety problem become global, and occupy very large proportion wherein by the chaufeur Road Traffic Injury accident caused of drinking.According to incompletely statistics, the death toll that the whole world causes because of traffic accident is every year just more than 1,500,000, and economic loss is about 20,000,000,000 dollars.Investigation according to the nearly 3 years World Health Organigation shows, the traffic accident of nearly half is all directly or indirectly relevant with drunk driving, drives when intoxicated and becomes one of chief reason causing traffic accident.
At present, in world wide, alcohol detection is main operating mode with expiration alcohol Concentration Testing.The way that this scene is detected navigating mate, easy, fast there is very strong operability, but the period that its detects be only limitted to the period of traffic police personnel on site supervision.And coverage is often Some vehicles.For individual car owner, the mode of this Product checking is random.Due to drunk driving behavior inherently a kind of minority behavior, its generation very disperses, the generation of phenomenon of therefore can not fundamentally stopping to drive when intoxicated.Multiple vehicle-mounted alcohol test system had been there is in recent years in some developed countries.Such as: in Sweden, the load-carrying vehicle of nearly thousand Volvo has installed a kind of device being called alcolock, this device be installed in automobile keeps mode of operation before car door opening to vehicle startup, navigating mate must carry out air blowing facing to device and detect before car engine, if test result is nonconformity, device just controls vehicle and carries out self-locking.But this alcolock is very easily practised fraud.For this reason, Italy has people to design a driving alcohol-detection instrument, near chaufeur, it is provided with 3 small-sized detecting heads, alcohol concentration from the gas that three position probing chaufeurs are breathed out, when device detects that in ambient air, alcohol concentration exceedes security level, alarm device will give a warning.And this device itself has the feature of continuous firing, even if some chaufeur is practised fraud, the personnel do not drunk are allowed to replace driver to start automobile, automobile starting, this detection instrument can continue to detect in car running process, if detect, navigating mate still exceeds standard, and control system can force car deceleration until stop.The vehicle-mounted alcohol test system of current various countries design adopts single-sensor mostly, error is large, specific air flow field in car can not be taken into full account, be difficult to fine popularization, and the multisensor designed can overcome the confinement problems of single-sensor information gathering point well herein.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of vehicle-mounted alcohol testing system, combined with sensing technology, signal processing technology and mode identification technology, with 51 series monolithics for core, and design vehicle-mounted alcohol testing system.This system can judge whether chaufeur drinks and Drinking level, and can assist and make respective reaction, is intended to the generation preventing drunk driving.
The technical solution adopted in the utility model is:
A kind of vehicle-mounted alcohol testing system, comprise safety lock device, main control unit, alcohol detecting device, displaying alarm, it is characterized in that: described alcohol detecting device is the comprehensive alcohol detecting device of multisensor, comprise air Alcohol mental disorders device, sweat alcohol sensor, acceleration pick-up, microcam and facial recognition modules; Air alcohol concentration sensor is arranged in car, judges whether he drinks by the alcohol concentration detecting chaufeur breath; Whether the sweat that sweat alcohol sensor detection chaufeur is secreted on hand is containing alcoholic content; Acceleration pick-up is preset in control loop, for judging that can chaufeur normally travel along track, as auxiliary judgment; Microcam is arranged on instrument panel center position, for identifying facial expression.
Further, described safety lock device is arranged on car door place, and safety lock device adopts based on the circuit of MQ3 switch circuit.
Further, described main control unit is arranged in car body, and main control unit is that employing is the circuit of major control with micro controller system and adopts fuzzy reasoning principle to programme.

2h
5oH alcohol detection circuit.
Further, described displaying alarm comprises LCDs and buzzer warning.
The function of every detecting device of the present utility model: whether (1) safety lock device can be drunk by expiration preliminary judgement navigating mate; (2) alcohol detecting device can determine chaufeur Drinking level: can analyze sweat alcohol concentration and chaufeur face frequency of wink information on alcohol concentration in air, control stalk; (3) whether the data analysis that main control unit can provide according to alcohol detecting device goes out is that navigating mate is drunk, and gets rid of passenger and to drink interference, and energy is corresponding give the alarm or the instruction of ramp to stop; (4) displaying alarm can make corresponding display according to master control instruction.
The vehicle-mounted alcohol testing system designed herein, adopts 51 series monolithics as main microcontroller, adopts multiple sensor collection information, and utilizes fuzzy algorithm processing data, judges whether chaufeur drinks and Drinking level.
Concrete program is: (1) is detected before driving: mandatory requirement navigating mate was carried out traditional expiration alcohol detection by system before running car, and this result, as anticipation, determines that can automotive lock be opened;
(2) detect in driving: system automatic detection chaufeur and passenger's expiration alcohol concentration in vehicle traveling process, qualification is that chaufeur is drunk or passenger drinks; In driving procedure, if chaufeur contact gear level, pick up camera can start facial-recognition security systems, make identification, detect the facial expression of chaufeur at any time, by detecting open and-shut mode and the statistics per minute number of winks of driver's eyes, computerized control system calculates through information algorithm fusion, can judge whether the consciousness of chaufeur regains consciousness;
(3) testing result and next step operation control process: if the alcohol comprehensive detection coefficient of chaufeur exceedes security level, when system judges navigating mate as drunk driving, system sends sound and light alarm and by liquid crystal display display reminding information, trigger warning device in car immediately, prompting chaufeur pulls over car rest, if chaufeur does not listen advice, control automobile constantly slows down by system, until stop travelling.In addition, checking system can keep one hour, without the need to again carrying out alcohol detection in the short time after stopping driving engine.
The utility model is the comprehensive alcohol detection system of vehicle-mounted multisensor based on fuzzy reasoning principle, is the perfect in shape and function on prior art basis and strengthening; Be provided with multiple detected parameters and the different sensor of each correspondence of each parameter, whether due to the multi-faceted property of system information acquisition, can effectively distinguish is that chaufeur is drunk, and gets rid of the interference that passenger drinks.This invention perfect in shape and function, implementation is strong, has important Research Significance, has vast potential for future development at home.
The vehicle-mounted alcohol testing system that the utility model provides, the beneficial effect brought:
1. prevent from practising fraud in testing process.
2. many parameters and the different sensor of each correspondence of each parameter, uses fuzzy reasoning to carry out calculating and has lower error.
3. aid parking function prevents unexpected generation.
