Abstract
The utility model comprises an automobile safety belt-based automatic control device, mainly comprising a safety belt, a safety belt plug and a seat. Alcohol sensors are disposed on the surface of the safety belt, at two top sides of the seat and to the top of an automobile. The alcohol sensors are connected with a single-chip microcomputer, the output terminal of which is connected with an automobile ignition switch, a liquid crystal display screen and a buzzer. A pull switch is arranged to the safety belt at a position adjacent to the safety belt plug. The automobile safety belt-based automatic control device, which is relatively high in precision and easy to operate, allows the driving operation only when the safety belt is tightly buckled and a driver's alcohol concentration dose not exceed a threshold concentration, thereby effectively enhancing the driving safety.
Description
Technical fieldThe utility model relates to a kind of warning restraint device, especially a kind ofly is used for the automatic control device that anti-fan driver is driven when intoxicated and driven with safety belt buckling free.
Background technologyAs everyone knows, automobile is current social topmost transport facility.But when driving, the bad habit that some driver safety belt buckling free often occurs or drives when intoxicated make the automobile accident accident increase, and bring serious potential safety hazard and property damage to people.At present, traffic supervision and some safety precautions systems are place in operation all, but mode falls behind, efficient is lower, can't produce a desired effect, and can't stop the potential safety hazard of drunken driving and safety belt buckling free.
Nowadays at present; Mainly contain in the market that following four kinds of devices can prevent and limit driver's drunken driving and safety belt buckling free is driven, as: based on the prevention drunken driving key of alcohol sensor, system for prompting, hand-held alcohol tester and the vehicle carried alcohol sensor of safety strap.; All there is deficiency separately in above-mentioned four kinds of devices, and for example: the prevention drunken driving key of alcohol sensor needs the driver before driving, to take mouth air blowing test; Can open key lock after qualified drives then; Though that but this measure can obtain certain effect limitation is too big, the driver adopts some electron keys also can directly unblank if do not open the lock with the key, if just and key loss can't play effect; Seat belt reminder systems only accomplishes only that reminding effect does not really go to implement automobile control, and has drawback such as driver's feint spike safety strap; The hand-held alcohol tester is too passive in use, can't initiatively limit and unblank; Vehicle carried alcohol sensor can be effective to a certain extent, but current alcohol sensor is installed in gauge panel or steering wheel position, and its accuracy of detection is lower, whether the driver is drunk can not make accurate judgement.
In sum, there is not a kind of detection control apparatus can thoroughly prevent the problem that the driver drives when intoxicated and safety belt buckling free is driven in the market now.
Summary of the inventionThe purpose of the utility model provide a kind of must fasten seat belts and after alcohol detection is qualified, can drive based on the car belt automatic control device.
The utility model mainly comprises safety strap, safety strap plug and seat; At safety strap surface, both sides, back of seat top and roof alcohol sensor is installed respectively; Alcohol sensor is connected with micro controller system, and the micro controller system mouth is connected with automobile ignition switch, LCDs and buzzer phone; Near safety strap plug position place the stretching switch is installed at safety strap; Said alcohol sensor adopts the MQ3-03 sensor; Said micro controller system adopts the Ling Yang micro controller system; Be provided with reflective tape on the safety strap surface.
Before the driving, if the driver does not insert the plug of safety strap in the buckle of seat, then automobile igniter is not worked, and automobile can't start.After fastening seat belts; Each alcohol sensor begins alcohol gas concentration signal in the inspection vehicle, through signal condition and A/D conversion, gets into the single-chip data emerging system; After micro controller system handle to be judged, inform the chaufeur degree of drinking through LCDs and buzzer phone.If alcohol concentration exceeds standard, then liquid crystal display alcohol concentration also sounds a warning, simultaneously buzzer call.If chaufeur drives by force, micro controller system detects the power supply of not fastening the safety belt or then cutting off automobile igniter during drunken driving, forbids automobile starting.For avoiding running into the situation of being inconvenient to stop, the back time-delay 30s that reports to the police sends control signal, treat alarm release after 10s inner control signal promptly disappear, automobile just can restart; If alcohol content does not exceed standard, automobile starts thereupon.
Compared with present technology; The beneficial effect of the utility model is: detect the alcohol concentration in the chaufeur breath through the many places alcohol sensor; Promote the accuracy rate of alcohol screen test greatly, and can realize auto-lock function, the problem of avoiding driving when intoxicated and driving with safety belt buckling free.
Description of drawingsFig. 1 is the hardware circuit diagram of the utility model.
Fig. 2 is the workflow diagram of the utility model.
Fig. 3 is the structure diagram of the utility model.
The specific embodimentIn the structure diagram of the utility model shown in Figure 3; Mainly comprise safety strap 1, safety strap plug 2 and seat 3; At safety strap mounted on surface alcohol sensor 4, alcohol sensor is connected with micro controller system, and the micro controller system mouth is connected with automobile ignition switch, LCDs and buzzer phone; Near safety strap plug position place stretching switch 5 is installed at safety strap.In both sides, back of seat top and roof alcohol sensor is installed also, and this alcohol sensor is connected with micro controller system also.Said alcohol sensor adopts the MQ3-03 sensor.Said micro controller system adopts the Ling Yang micro controller system.Be provided with reflective tape 6 on the safety strap surface.
Concrete workflow is: the alcohol sensor initialization finishes and begins heating, and behind sensor heating 10s, miniature air extractor begins the gas that the driver breathes out is gathered.If the explanation driver did not have drunken driving when " HAVE A GOOD TIME " appearred in LCDs, can normally start automobile this moment.If LCDs shows when being " STOP DRIVING YOUR BAC IS * * * * * * * "; Explain that alcohol concentration exceeds standard in the gas that the driver breathes out, this moment, buzzer phone sounded, and system judges that the driver is a drunken driving; The power supply of automatic cutout automobile; This moment, buzzer phone sounded, and reminded the driver to drive, and took care.Whether if the driver will test again and press RESET, can test the driver again is drunken driving.
