A kind of anti-drunk driving Hull-Mounted Set
Technical field
The utility model relates to a kind of anti-drunk driving Hull-Mounted Set, belongs to helmet technical field.
Background technology
When driving motorcycle or electric motor car, the existing legal provisions driver of China must helmet.When meeting with a street accident, can protect driver's head safety like this.The existing helmet generally only includes helmet body and protective layer.But these helmets only shield, cannot realize anti-drunk driving function.According to data, a lot of traffic accidents are all driven when intoxicated relevantly with the driver of motorcycle and electric motor car, so be necessary the present helmet to be improved, increase anti-drunk driving function.
Summary of the invention
The utility model provides a kind of anti-drunk driving Hull-Mounted Set, for solving the problem that the common helmet can not anti-drunk driving.
The technical solution of the utility model is: a kind of anti-drunk driving Hull-Mounted Set, comprise the alcohol gas sensor 1 that is positioned at helmet body spiracle 9 inner sides, be positioned at A/D converter 2, single-chip microcomputer 3, power supply 5, the power supply lid 7 at helmet ontology cache layer 8 place, be positioned at the recline buzzer 4 at ear place of helmet main body protection layer 10, helmet body housing 6, helmet ontology cache layer 8, helmet body spiracle 9, helmet main body protection layer 10; Wherein alcohol gas sensor 1, A/D converter 2, single-chip microcomputer 3, buzzer 4 are connected with power supply 5 respectively, and alcohol gas sensor 1 is connected with A/D converter 2 again, and A/D converter 2, buzzer 4 are connected with single-chip microcomputer 3 again.
During use, while putting on the anti-drunk driving helmet before the person of sailing is being driven, by being arranged in advance 1 couple of driver's of alcohol gas sensor of helmet body spiracle 9 inner sides the gas of exhalation, carry out alcohol concentration detection; Then will obtain voltage value signal and be sent to A/D converter 2, through A/D converter 2, be scaled data signal, thereby obtain a value; This value will be sent in single-chip microcomputer 3, and be scaled BAC value by the proportionate relationship of BAC and gas alcohol concentration (BAC=2200 * gas alcohol concentration); Simultaneously with its internal memory in the FLASH ROM drunk driving reference value (20g/100L) of preserving compare:
If BAC value is less than reference value, show not to be drunk driving state, now, single-chip microcomputer 3 can not activate buzzer 4, and buzzer 4 can not produce alarm sound.
Otherwise, showing it is drunk driving state, single-chip microcomputer 3 can activate buzzer 4, and buzzer 4 can produce alarm sound, reminds driver overproof, and drunk driving is dangerous.
The beneficial effects of the utility model are: outward appearance simple in structure, with low cost, not affect the helmet, can remind in time driver according to alcohol content, and prevention is driven when intoxicated, and has reduced traffic accident.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but content of the present utility model is not limited to described scope.
Embodiment 1: as Figure 1-4, a kind of anti-drunk driving Hull-Mounted Set, comprise the alcohol gas sensor 1 that is positioned at helmet body spiracle 9 inner sides, be positioned at A/D converter 2, single-chip microcomputer 3, power supply 5, the power supply lid 7 at helmet ontology cache layer 8 place, be positioned at the recline buzzer 4 at ear place of helmet main body protection layer 10, helmet body housing 6, helmet ontology cache layer 8, helmet body spiracle 9, helmet main body protection layer 10; Wherein alcohol gas sensor 1, A/D converter 2, single-chip microcomputer 3, buzzer 4 are connected with power supply 5 respectively, and alcohol gas sensor 1 is connected with A/D converter 2 again, and A/D converter 2, buzzer 4 are connected with single-chip microcomputer 3 again.
