As shown in fig. 1, the fatigue driving intervention system provided by the present application includes a power supply 10, a controller 20, a visual monitoring device 30, a speaker device 40, and a voltage stimulation device 50. In the fatigue driving intervention system, the controller 20, the visual monitoring device 30, and the speaker device 40 are electrically connected to the power supply 10, and the power supply 10 supplies sufficient operating power to the controller 20, the visual monitoring device 30, and the speaker device 40. The visual monitoring device 30 and the speaker device 40 are respectively in communication connection with the controller 20 (in the fatigue driving interference system, the communication connection mode may be a wired connection mode to implement electrical signal communication, and the communication connection mode may also be a wireless communication mode to implement electromagnetic wave signal communication), in fig. 1, the dotted line represents the communication connection mode and the directional arrow represents the communication direction, it can be known that in the fatigue driving interference system, the communication paths are respectively three one-way communication path directions from the controller 20 to the visual detection device 30, from the controller 20 to the speaker device 40, and from the controller 20 to the voltage stimulation device 50. The voltage stimulation device 50 includes a device power supply, a signal control module, and positive and negative plates, the signal control module is electrically connected to the device power supply, the positive and negative plates are electrically connected to the signal control module, the signal control module is in communication connection with the controller 20, when the voltage stimulation device is used, the voltage stimulation device is worn on the body of the driver, and the positive and negative plates are respectively in contact with the skin of the driver.

The fatigue driving interference system is applied to the driving process of a driver, the driver starts the fatigue driving interference system before driving, and the visual monitoring device 30 is aligned to a driving position, so that the visual monitoring device 30 can accurately acquire information such as facial expressions and limb actions of the driver in the driving process, and the voltage stimulation device 50 is worn on the body to enable positive and negative pole pieces to be in contact with the skin. When a driver drives for a long time, fatigue driving is easy to occur, generally, the driver should drive to get on the road after having a rest after driving for 4 hours, of course, the time length of the occurrence of the fatigue driving situation is different for different drivers, and the driver often continues driving unconsciously even though the driver is in fatigue driving. At this time, the driver in fatigue driving may present facial expressions and body movements representing fatigue states, such as mouth opening and closing frequency, eye closing frequency, body movements of hands covering the face, body movements of head deviation, and the like, and these information may be captured by the visual monitoring device 30 and converted into image information to be transmitted to the controller 20, and after the controller 20 receives these information, the information is analyzed, so as to determine and identify whether the driver is in fatigue driving state at this time. When the controller 20 analyzes and judges that the driver is in the non-fatigue driving state from the received information, the controller 20 receives the information again and analyzes and judges the information; when the controller 20 analyzes and judges that the driver is in the fatigue driving state from the received information, the controller 20 further identifies the fatigue driving degree of the driver and classifies the fatigue driving degree into a preliminary fatigue state and a drowsy fatigue state, when the controller 20 judges that the driver is in the preliminary fatigue driving state according to the received information, the controller 20 sends an operating instruction to the speaker device 40, the speaker device 40 sends a warning reminding sound to the driver after receiving the instruction to remind that the driver is in the fatigue driving state, when the controller 20 judges that the driver is in the drowsy driving state according to the received information, the controller 20 sends an operating instruction to the voltage stimulation device 50, the voltage stimulation device 50 applies voltage stimulation to human nerve endings through positive and negative pole pieces after receiving the instruction, so that the driver can be capable of aroused briefly, and quickly find the rest place (of course, when the controller 20 analyzes and judges that the driver is in the dozing fatigue state according to the received information, the controller 20 may also simultaneously issue an operation instruction to both the speaker device 40 and the voltage stimulation device 50, so that the driver can temporarily catch mind while receiving the voltage stimulation, and can also further hit twelve minutes of mind under the sound alarm of the speaker device 40, and then quickly find the nearest rest place to stop and rest). Therefore, in the process of driving on the road by the driver, as long as the driver is in a fatigue driving state, the fatigue driving interference system can actively intervene and remind the driver to warn that the driver is in a dangerous situation of fatigue driving, so that the driver can realize the danger of fatigue driving, the driver can actively stop and rest, the driver always keeps full spirit to drive on the road, and the tragedy of traffic accidents caused by the fatigue driving of the driver can be avoided as much as possible.
