Embodiment 1

[0022] Depend on figure 1 As shown in the system structure diagram, an application example of the present invention: a camera with automatic infrared lighting is installed in the range of the driver's front line of sight (reversing mirror), and the visible light video images are continuously collected during the day and near night during the driving of the vehicle. Infrared video image; the video image output of the camera is connected to the image acquisition card (MV-AINI3.0); the image acquisition card (MV-AINI3.0) converts the video analog image signal into a digital image signal that can be processed and recognized; the engine The speed acquisition card (KPCI-812) is connected to the vehicle engine speed sensor, and the engine speed signal is the basis for the system to identify the working state of the vehicle; the driving speed acquisition card (KPCI-812) is connected to the vehicle speed sensor to provide the driving speed signal It is the basis for the system to judge...

Abstract

The invention relates to a vehicle driver anti-drowsy automatic emergency stop device which comprises a video camera and an image processing single board computer, and has the technical key points that the video camera is arranged at the position corresponding to the eye part of the sight line in front of a driver inside a cab; a video image output end of the video camera is connected with the image processing single board computer, and an input end of the image processing single board computer is also respectively connected with an engine rotating speed signal output end and a running speed signal output end of a vehicle computer; an output end of the image processing single board computer is respectively connected with an accelerator controller, a braking controller, an alarm device andan input end of a dual flash relay. Once the driver has the drowsy dangerous situation when in driving, an execution driving controller can lead the driver to be converted into a safe state by the functions of audible alarm and controlling dual flash, brake force and an accelerator. The device has simple structure and reliable use, and can effectively prevent the driving accident caused by the driver who dozes off when in driving.

Description

technical field [0001] The invention relates to the technical field of preventing fatigue driving of motor vehicle drivers and ensuring driving safety, in particular to an emergency automatic parking device for preventing drowsiness of motor vehicle drivers. Background technique [0002] As we all know, when a motor vehicle is running for a long time, the driver is prone to fatigue and drowsiness, which can easily cause traffic accidents and seriously affect the property and life safety of the driver himself and others. [0003] In recent years, in expressway driving, major traffic accidents caused by drowsiness of drivers have increased exponentially. Therefore, countries all over the world are doing a lot of research and development on vehicle-mounted drowsiness prevention devices for drivers. Such as identifying brain waves, judging sleep posture, brain position deviation, hand grip changes, blink frequency judgment, etc. Because all there is the uncertainty of judging t...
