Drawings
FIG. 1 is a schematic view of the structure principle of the present invention;
fig. 2 is a flow chart of the present invention.
In the figure, an alarm module 100, a buzzer 110, an alarm indicator 120, a driving position pressure sensor 200, a controller 300, a detection module 400, an alcohol concentration sensor 410, a pulse sensor 420 and an ignition control device 500 are shown.
Detailed Description
As shown in fig. 1, the utility model provides a novel driver fatigue and wine drive early warning car-mounted device, wherein include:
an alarm module 100, the alarm module 100 comprising: a buzzer 110 disposed on a left door of a driver's seat; and the alarm indicator lamp 120 is arranged below the central control display screen. When the detection device obtains that the driver is in the drunk state or the mental fatigue state, the warning device is used for reminding and warning the driver, and the effect of discouraging the driver from drunk driving and fatigue driving is achieved.
And a driver seat pressure sensor 200, which is disposed below the main driver seat, for detecting whether the driver is seated. Controller 300, the utility model discloses the controller adopts 51 singlechips, receives the testing result signal that detection device transmitted and judges whether driver fatigue driving or drunk driving, if driver exists above the action, then sends corresponding execution signal to alarm module or ignition control device.
A detection module 400, which includes an alcohol sensor 410, located on the a pillar of the vehicle near the driver's seat, for detecting the alcohol concentration in the cab of the vehicle; the pulse sensor 420 is located on the steering wheel, and is used for detecting the pulse velocity of the driver when the driver holds the steering wheel, determining whether the driver is drinking by using the dual criteria of the alcohol concentration in the air and the pulse velocity of the driver, properly reducing the criteria of the alcohol concentration by considering that the alcohol concentration sensor 410 of the device is at a certain distance from the driver, obtaining the blood alcohol concentration of the driver by converting the alcohol concentration in the breath of the driver, and determining that the driver is drinking when the blood alcohol concentration of the driver is detected to be more than or equal to 5mg/100ml, wherein the blood alcohol concentration is 2200 breath alcohol concentration multiplied, in order to prevent the false determination of the alcohol concentration sensor 410 caused by the fact that the driver is not drinking and the passenger is drinking. Separately, if the alcohol concentration sensor 410 does not detect that the driver is drinking, the pulse sensor 420 is activated to detect the pulse velocity of the driver and determine whether the driver is in a mental fatigue state. The device stores the average pulse speed of the driver within five days, compares the average pulse speed with the real-time pulse speed of the driver, and judges that the driver is tired if the average pulse speed is exceeded.
And an ignition control device 500 for receiving the control signal from the controller and switching on or off the ignition circuit of the vehicle.
Referring to fig. 2, the method of the present invention includes the following steps:
the driver seat pressure sensor 200 detects that the driver enters the vehicle and transmits a signal back to the controller.
The controller activates the detection module 400, the alcohol concentration sensor 410 detects the alcohol concentration in the automobile cab, and if the blood alcohol concentration of the driver is less than 10mg/100ml, the driver is judged not to be drunk. Then the pulse sensor 420 detects the pulse condition of the driver, determines whether the driver is in a mental fatigue state, and if the pulse speed of the driver does not exceed the average pulse speed, the device does not continue to work. If the pulse velocity of the driver exceeds the average pulse velocity, it is determined that the driver is tired, and the controller 300 sends an execution signal to the alarm module 100.
If the alcohol concentration in the driver's cab is greater than or equal to 10mg/100ml, the pulse sensor 420 on the steering wheel continues to work to detect the pulse condition of the driver, and if the pulse speed of the driver does not exceed the average pulse speed, the device does not continue to work. If the pulse velocity of the driver exceeds the average pulse velocity, it is determined that the driver drives after drinking, and the controller 300 sends an execution signal to the alarm module 100 and the ignition controller 500.
After receiving the execution signal of the controller, the alarm module 100 turns on the buzzer 110 and lights the corresponding alarm indicator 120 to remind the driver of the drunk state or the mental fatigue state.
After receiving the execution signal from the controller, the ignition controller 500 controls the ignition system of the automobile and cuts off the ignition circuit, so that the driver cannot start the automobile, and dangerous driving behaviors are avoided.
