Description
The technical field is as follows:
the utility model belongs to the technical field of the interior electron of car and specifically relates to an early warning device for when driver fatigue driving.
Background art:
studies have shown that a driver reacting 1 second before a traffic accident will reduce the accident by 60%. Similarly, if a method is available to monitor the fatigue driving degree of the driver and give an early warning, the fatigue driving accident will be reduced significantly. At present, a method based on physiological signal monitoring, a method based on physical reaction of a driver, and a method based on a vehicle driving state are more popular methods in fatigue driving monitoring. Although some devices for detecting facial images of a driver through a camera and judging whether the driver is tired to drive and early warning through changes of eye images of the driver appear in the prior art, the device has the following application numbers: 201510335822. X; 201911422535.7, respectively; 201910174476. X; 201910150579.2, etc. However, most of them adopt the form of sound and light alarm, but when the driver is listened, and suddenly receives sound and light stimulation from the outside, the driver will be confused, and the misoperation will be made, so that the danger is caused.
The utility model has the following contents:
the utility model discloses be exactly in order to overcome not enough among the prior art, provide an early warning device when being used for driver fatigue driving.
The application provides the following technical scheme:
the utility model provides an early warning device for driver fatigue driving time, it is including setting up the camera of shooting driver's face in when driving, is equipped with the display on the driver's cabin, is equipped with embedded treater, its characterized in that in the driver's cabin: be equipped with steering wheel steering angle inductor, a pair of pressure sensors and reset switch on the steering wheel, install at least one vibrating motor in the seat, camera, steering wheel steering angle inductor, pressure sensors, reset switch vibrating motor and indicator switch all form the cooperation of signal connection through circuit and treater.
On the basis of the technical scheme, the following further technical scheme can be provided:
and a double-flashing-light switch on the driving platform is matched with the processor in an electric signal connection way.
The camera is an infrared camera and is used for collecting facial images of a driver.
The display liquid crystal display screen comprises an image display area and a touch screen control area.
Utility model advantage:
the utility model discloses simple structure, low cost, convenient to use, the alarm of emitting that can be timely, and the alarm send softly remind the driver in time to park and have a rest, when avoiding driver fatigue, have the amazing driver of alarm of having avoided sending suddenly, cause the maloperation.
Description of the drawings:
fig. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of the structure of the steering wheel.
The specific implementation mode is as follows:
as shown in figures 1 and 2, the early warning device for fatigue driving of the driver comprises a camera which is arranged in the driving process and used for shooting the face of the driver, and the camera is an infrared camera and used for collecting the face image of the driver in real time. The collected image information is transmitted into an embedded processor embedded in the driving platform through a line, the input image information is detected and identified by software built in the processor, and when the driver continuously acts like through hole downward, eyelid drooping, eye closing, yawning, head lowering and the like, the processor determines that the driver enters a fatigue driving state. The processor will issue an alarm signal.
The driver's seat is provided with a display and a display liquid crystal display screen, wherein the display liquid crystal display screen comprises a touch screen control area close to the driver side and an image display area close to the passenger seat side. The driver can control other devices in the vehicle such as an air conditioner, a sound, a radio and the like in the touch screen control area, the face image of the driver is displayed in real time in the image display area so that the driver can check the mental state of the driver, and the driver can be timely found to remind the driver when the driver begins to be depressed.
The steering wheel is provided with a steering wheel steering angle sensor for detecting the steering angle of the steering wheel. When the steering lamp switch is not turned on, the steering angle sensor of the steering wheel exceeds 10 degrees and lasts for 0.5 second; beyond 5 deg. for 1 second, the processor will send out a normal driving prompt.
A pair of vibration motors is installed on the inner side of the skin of the seat in the driving position, and when the vibration motors receive the alarm signals sent by the processor, the vibration motors are started to send out vibration to remind a driver. Meanwhile, after the vibration motor is started, a motor starting signal is sent to the processor.
When the display receives an alarm signal sent by the processor, the picture of the image display area sends red light to prompt a driver and people in the vehicle, and after the red light is sent for 2 seconds, the voice prompt module embedded in the display starts to play voice prompts, so that the driver and the people in the vehicle are further reminded. The volume is increased gradually by little after voice prompt begins to play a second, and when the volume is increased to the maximum, the display can send the complete start signal to the treater, and at this moment the treater will send the signal to two flashing light switches, then two flashing lights open once and remind the rear to come the car and notice dodging.
The steering wheel is also provided with a pair of pressure sensors and a reset switch, and the pressure sensors are in electric signal connection and matching with the processor through a circuit. The two pressure sensors 3 are respectively arranged on the rims 2 at the left side and the right side of the horizontal direction of the spoke 1 of the steering wheel, the corresponding positions are the o 'clock position and the 3 o' clock position of the rim, and the reset switch 4 is positioned on the spoke.
When a driver holds the steering wheel with two hands during normal driving, so that the pressure sensor area is pressed, the processor can receive signals sent by the two pressure sensors. When the driver drives the unnormal, namely when the driver holds the steering wheel by one hand, the processor can only receive the signal sent by one pressure sensor, and when the signal sent by one pressure sensor can only be received for 3 seconds, the processor can send out a standard driving prompt signal.
After the display receives the standard driving prompt signal, a voice prompt module embedded in the display emits a prompt tone for 'please standardize driving'. Thus reminding the driver to drive normally, namely turning on the turn light first and then turning to; and holding the steering wheel with both hands while driving.
When the driver is reminded to do spirits or to drive normally, the reset switch is manually pressed, the reset switch sends a signal to the processor, and then the processor resets the vibrating motor, the display and the double-flashing-lamp switch.
