Description
Technical field
The utility model belongs to driver assistance driving technique field, is specifically related to a kind of bearing circle of early warning driver tired driving.
Background technology
Fatigue driving is the key factor causing traffic accident.China occupies first place in the world because of arteries of communication injures and deaths number every year, and with annual 10% speed increase, the traffic accident that fatigue driving causes is also with quickish speed increase.For Beijing, the traffic accident caused because of fatigue accounts for more than 20% of total number of accident.Fatigue driving has become the key factor of traffic accident, and the safety of life and property of people in serious threat; If can fast, in real time, effectively detect fatigue driving state and send early warning signal to chaufeur, the probability that traffic accident occurs effectively can be reduced.
Driving fatigue refers to that the reaction level produced after the driving of a period of time declines.Slow in reacting, judge slow, stiff in the movements, rhythm is slow etc. is the main forms of driver fatigue.Various comprehensive research display, the operating frequency of bearing circle and grip (or pressure) degree comparatively directly can characterize chaufeur and whether be in fatigue driving state.
Utility model content
In order to overcome the defect that above-mentioned prior art exists, the purpose of this utility model is the bearing circle providing a kind of early warning driver tired driving, the utility model carries out early warning based on grip (or pressure) actv. of detection chaufeur to bearing circle to driver tired driving, and simple to operate, there is higher practicality and realizability.
For achieving the above object, the utility model adopts following technical scheme:
A kind of bearing circle of early warning driver tired driving, comprise bearing circle bracing frame, the handrail circumference of bearing circle bracing frame is fixed with some pressure sensors of connecting successively, bearing circle bracing frame is also fixed with fatigue driving early-warning device, described fatigue driving early-warning device comprises housing, enclosure interior is provided with micro controller system, early warning flashing lamp and early warning sound equipment, housing is also provided with the X button can closing early warning flashing lamp and early warning sound equipment, described pressure sensor is connected with the input end of micro controller system, early warning flashing lamp is connected with the mouth of micro controller system with early warning sound equipment.
Further, described pressure sensor comprises solid dielectric, be evenly fixed on the movable plate electrode of solid dielectric side and be fixed on the deciding grade and level plate of solid dielectric opposite side.
Further, described pressure sensor is 24 and is evenly distributed on the handrail circumference of bearing circle bracing frame.
Further, described pressure sensor is type polar distance variable capacitance formula sensor.
Further, the comparator of the pressure measuring value for comparative pressure setting value and pressure sensor is provided with in described micro controller system.
Compared with prior art, the utility model has following useful technique effect:
The utility model holds the situation of bearing circle pressure by arranging pressure sensor, and this situation is sent to micro controller system, fatigue driving is judged whether by micro controller system, and send early warning by early warning flashing lamp and early warning sound equipment, also be provided with X button, when chaufeur feels early warning information, early warning can be closed by this button of Non-follow control, structure is simple, easy and simple to handle, chaufeur can carry out independent operation without the need to carrying out special training, and each parts are all ripe, the utility model is applicable to the long driving fatigue early warning of chaufeur, the turnpike driving giving fatigue pre-warning that special adaptation is nowadays multiple, and light early warning and sound early warning act synergistically, early warning effect is more remarkable, simple improvement and installation can be carried out on existing bearing circle simultaneously, practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1 to Fig. 3, a kind of bearing circle of early warning driver tired driving, comprise bearing circle bracing frame 1, the handrail circumference of bearing circle bracing frame 1 is evenly fixed with 24 pressure sensors of connecting successively 2, described pressure sensor 2 comprises solid dielectric 9, evenly be fixed on the movable plate electrode 8 of solid dielectric 9 side and be fixed on the deciding grade and level plate 10 of solid dielectric 9 opposite side, described pressure sensor 2 is type polar distance variable capacitance formula sensor, bearing circle bracing frame 1 is also fixed with fatigue driving early-warning device, described fatigue driving early-warning device comprises housing 3, housing 3 inside is provided with micro controller system 4, early warning flashing lamp 6 and early warning sound equipment 7, the comparator of the pressure measuring value for comparative pressure setting value and pressure sensor 2 is provided with in described micro controller system 4, housing 3 is also provided with the X button 5 can closing early warning flashing lamp 6 and early warning sound equipment 7, described angular velocity sensor is connected with the input end of pressure sensor 2 with micro controller system 4, early warning flashing lamp 7 is connected with the mouth of early warning sound equipment 7 with micro controller system 4.
Below implementation process of the present utility model is described in further detail:
See Fig. 4, from vehicle launch, namely pressure sensor 2 starts the situation detecting the power holding bearing circle, and the grip or force value of holding bearing circle are passed to micro controller system 4, a pressure set points 10N is provided with in comparator in micro controller system 4, pressure set points in the force value that pressure sensor 2 records by comparator and comparator compares, judge whether bearing circle is subject to being greater than grip or the pressure of 10N, if, it is then normal driving, if not, it is then fatigue driving, judged result is flowed to early warning flashing lamp 6 and early warning sound equipment 7 by micro controller system 4, when fatigue driving, early warning flashing lamp 6 carries out flicker early warning, the sound equipment of early warning simultaneously 7 plays corresponding driving fatigue warning statement, when chaufeur receive early warning information and vigilance time, by X button 5, early warning flashing lamp 6 and early warning sound equipment 7 can be closed, can again judge that whether chaufeur is tired after closedown, circulate according to this, if chaufeur does not realize early warning, illustrate that chaufeur is still in fatigue driving state, then early warning flashing lamp 7 and early warning sound equipment 7 continue early warning.
