Problems solved by technology

These technologies and equipment have played a certain role in use, but there are also great limitations. For example, fatigue state detection is only effective for some drivers, and it is impossible to perform accurate fatigue detection for all drivers; alcohol odor detection in the cab There is a large difference between ventilation and non-ventilation conditions, and it is impossible to accurately determine whether the driver is drinking or not
These limitations limit the popularization and use of the above-mentioned active safety technologies and equipment for motor vehicle driving, and cannot completely avoid road traffic accidents,...

Embodiment 1

[0039] Such as figure 1 As shown, a system for remote monitoring and abnormal warning of drivers, including a video detection machine 1 for detecting and judging the direction of the driver's line of sight and a GPS / Beidou dual-mode receiver for detecting the position and speed of the motor vehicle Device 2, the output end of described video detection machine 1 and GPS / Beidou dual-mode receiver 2 is respectively electrically connected with the input end of the processor 3 that is used for processing data and judging driver's attention; The output of described processor 3 Terminal is electrically connected with alarm device 5. The output end of the processor 3 is electrically connected to a 3G wireless router 4 , and the 3G wireless router 4 communicates wirelessly with the background control center 6 .

[0040] Further, the video detection machine 1 includes a camera 1-1 and a host 1-2, the output end of the camera 1-1 is electrically connected to the host 1-2, and the output...

Embodiment 2

[0044] A method for remote monitoring and abnormal warning of drivers, comprising the following steps:

[0045] (1) When the light is good during the day, the infrared lighting is turned off, and the camera takes a picture of the driver's facial features and sends it to the host. Judging whether the driver is "left-looking", "right-looking" or "front-looking" based on the distance between them: L1L2 is "left-looking"; then according to the center of the line connecting the centroids of the left and right pupils The distance Dx between the point and the tip of the nose is compared with the distance Do when looking straight up to judge whether the driver is "looking up", "looking down" or "looking up": Dx>Do is "looking up", Dx figure 2 shown). If it is detected that L1>L2, DxL2, Dx=Do, Then it is judged that the driver is "left-looking", that is, observing the left side to observe the traffic situation on the left side of the motor vehicle. At the same time, the host transmits ...

Embodiment 3

[0052] A method for remote monitoring and abnormal warning of drivers, comprising the following steps:

[0053] (1) When the light is not good at night, the host drives the infrared lighting to turn on for supplementary light. The camera captures the video of the driver's facial features and transmits it to the host. The host locates the driver's eyes and nose according to the video, and the center of mass of the left and right pupils The distances L1 and L2 between the projected points of the tip of the nose and the distance between L1 and L2 are used to determine whether the driver is "left-looking", "right-looking" or "front-looking": L1L2 is "left-looking" Then, according to the distance Dx between the center point of the centroid of the left and right pupils and the tip of the nose and the distance Do when looking straight ahead, it is judged whether the driver is "looking up", "looking down" or "looking straight up": Dx> Do means "looking up", Dx figure 2 shown). If it ...

Abstract

The invention provides a system used for driver remote monitoring and driver abnormity early warning. The system comprises a video detecting machine used for detecting and judging the sight direction of a driver and a GPS/big dipper double-module receiver used for detecting the position of a motor vehicle and the running speed of the motor vehicle. The output end of the video detecting machine and the output end of the GPS/big dipper double-module receiver are electrically connected with the input end of a processor used for processing data and judging the attention of the driver. The output end of the processor is electrically connected with a warning device. The invention further discloses a method for remote monitoring and abnormity early warning. The sight direction of the driver is collected and detected through the video detecting machine, the position and the running speed of the motor vehicle are collected through the GPS/big dipper double-module receiver, therefore, judging of the attention states of the driver and detection of the abnormal states of the driver are realized, different warning measures are provided according to different abnormal states, and remote on-way driver real-time monitoring and remote on-way driver abnormity warning are realized. Thus, road traffic accidents are avoided.

Description

[0001] technical field [0002] The invention relates to the technical field of active safety of motor vehicle driving, in particular to a system and method for remote monitoring and abnormal warning of drivers. [0003] Background technique [0004] The rapid development of social economy has led to a surge in road traffic volume, and road traffic accidents have become an increasingly serious public safety problem worldwide. Statistics show that the highest rate of road traffic accidents caused by drivers' human factors accounts for about 90%, which brings serious harm to people's lives and property safety. Among the driver's human factors that lead to these highway traffic accidents, fatigue driving, drunk driving and distracted driving are one of the important reasons. According to analysis, the driver's inattention within 3 seconds caused 80% of the traffic accidents, mainly manifested as lane departure and rear-end collisions. [0005] In order to prevent road traffi...
