Abstract
The invention provides a fatigue driving early warning device, which comprises a camera, a processor and a display, and is characterized in that: set up steering wheel steering angle inductor and vibrating motor and alarm, camera, display, steering wheel steering angle inductor, vibrating motor, alarm and indicator switch all through circuit and treater stroke signal of telecommunication connection cooperation. The invention has simple structure, low cost and convenient use, can give out alarm in time to remind a driver to stop the vehicle for rest in time and avoid fatigue driving.
Description
The technical field is as follows:
the invention relates to the field of in-vehicle electronics, in particular to a fatigue driving early warning device.
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 and the like. 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 invention content is as follows:
the invention aims to overcome the defects in the prior art and provides a fatigue driving early warning device.
The application provides the following technical scheme:
the utility model provides a driver's facial camera is shot including setting up when driving to driver's early warning device, 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 the steering wheel angle inductor on the steering wheel, install at least one vibrating motor in the seat, still be equipped with the alarm on the driver's cabin platform, camera, steering wheel angle inductor, vibrating motor, alarm and indicator switch all form the signal of telecommunication through circuit and treater and connect the cooperation.
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 steering wheel is also provided with a pair of pressure sensors, and the pressure sensors are in electric signal connection and matching with the processor through circuits.
The alarm is a sound-light alarm, firstly gives out light alarm when being started, and then gives out prompt sound alarm.
The audible and visual alarm can be started only after the vibration motor is started.
The invention has the advantages that:
the alarm device has the advantages of simple structure, low cost and convenience in use, and can give out an alarm in time, and the alarm gives out softly to remind a driver to stop and rest in time, so that the driver is prevented from being stimulated by the suddenly-sent alarm to cause misoperation while fatigue driving is avoided.
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 fig. 1 and 2, the fatigue driving early warning device comprises a camera which is arranged in the driving process and used for shooting the face of a driver, wherein 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 display is arranged on the driver's seat, the face image of the driver can be displayed on the display in real time, so that the driver can check the mental state of the driver, and the driver can be reminded by timely finding the face image of the driver when the driver begins to become 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 angle sensor of the steering wheel exceeds 5 degrees and lasts for one second in the state that the steering lamp is not turned on, the processor can send out a standard driving prompt signal.
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.
Still be equipped with the alarm on the driver's cabin, the alarm be audible-visual annunciator, receive the motor after the start signal 1 second to audible-visual annunciator signals when the treater for audible-visual annunciator starts audible alarm's volume by little crescent, when audible alarm's volume increase to the biggest, audible-visual annunciator can send complete start signal to the treater, at this moment the treater will send a signal to two flashing light switches, then two flashing lights are opened once and are reminded the rear and come the car and notice and dodge.
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 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 alarm receives the standard driving prompt signal, a voice prompt module embedded in the alarm emits a prompt sound of '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 shake to work, the reset switch is manually pressed, the reset switch sends a signal to the processor, and then the processor resets the vibrating motor, the alarm and the double-flashing-lamp switch.
