Above-mentioned warning also can comprise a flash light, is connected in series an actuator between flash light and microcontroller.Flash light sends the light of flicker and reports to the police.
Above-mentioned warning also can comprise an electric shock pin, is connected in series a transistor between electric shock pin and microcontroller.The electric shock pin is generally worn on the wrist of chaufeur, can stimulate the skin on the chaufeur wrist to impel chaufeur clear-headed.Transistor plays amplification.
In this detection alarm device, behind amplifier, be sent to microcontroller by signal that the sensor obtained.In microcontroller, the signal that sensor obtained and the data that originally were stored in the microcontroller compare, and determine its difference and judge whether chaufeur enters fatigue state or driving a car under the influence of alcohol.In fact, blood pressure, arteries and veins picture or the degree of lip-rounding, the eyes of chaufeur under normal condition and fatigue state are to exist certain difference, and this device is just according to the basis of this principle as judgement.
If microcontroller judgement chaufeur has entered fatigue state or driving a car under the influence of alcohol, microcontroller just is sent to warning with alerting signal.Warning also can impel it clear-headed by the skin of electric shock needle stimulus chaufeur except send alarm sound and flicker warning light by loud speaker and flash light, makes chaufeur concentrate one's energy to drive or stop and has a rest.
Compared with prior art, advantage of the present utility model is:
1, this device is melted into a whole technology such as body science, radio and computing machine, has characteristics easy to use, accuracy of judgement.
2, in this device, features such as blood pressure, pulse condition or the eyes of utilization detection chaufeur, the shape of the mouth as one speaks are judged its fatigue state, and scientific and reasonable, error rate is low.
3, this device sends warning by loud speaker or electric shock pin, can impel chaufeur to keep a cool head, and concentrates one's energy to drive, and the traffic accident that effectively reduces human element and caused takes place.
