Description

Technical Field

[0001] The utility model relates to the field of anti-fatigue driving warning devices, in particular to an anti-fatigue driving warning device based on real-time monitoring of a driver's head state. Background Art

[0002] In the field of transportation, with the increase in vehicle ownership and the prevalence of long-distance driving, fatigue driving has become one of the main causes of traffic accidents. Traditional fatigue driving monitoring methods often rely on the driver's self-perception or simple vehicle driving data, which makes it difficult to accurately judge the driver's fatigue state in real time. Therefore, it is particularly important to develop an efficient and reliable anti-fatigue driving warning device. The device aims to accurately identify the driver's fatigue state by real-time monitoring of the driver's physiological signals, facial features or vehicle operating status, using advanced algorithms and sensor technology, and issue a warning when necessary, effectively preventing traffic accidents caused by fatigue driving and improving road traffic safety.

[0003] The patent document with announcement number CN212047170U discloses an anti-fatigue driving warning device, including a monitoring device and a judgment device. A rotating shaft is fixedly connected to the lower side of the connecting seat, and one end of the rotating shaft extends into the inner cavity and is fixedly connected to a turntable. A number of arc-shaped locking grooves are evenly arranged in an annular shape on the outer side of the turntable. A first spring is assembled inside the two step holes. The lower sides of the two limit blocks are fixedly connected to the limiting rod. The lower side of the slide plate is fixedly connected to an arc-shaped locking piece matching the arc-shaped locking groove. The top piece is fixedly connected to a sliding rod away from one end of the connecting seat. One side of the sliding rod extends into the inner hole and is sleeved with a second spring. The sliding rod passes through the second spring and is fixedly connected to a slider. One end of the sliding rod passes through the slider and is fixedly connected to a pressing block with a rotating seat. The device has a simple structure and is convenient for the driver to adjust the camera angle of the monitoring device according to actual needs. The camera angle will not deviate due to the shaking of the vehicle. However, the following deficiencies still exist.

[0004] The anti-fatigue driving warning device in the above patent document pushes the movable rod through a spring, and the movable rod drives the slide plate and the arc-shaped locking block at the bottom to abut against the inside of the arc-shaped locking groove. In actual work, when the warning device is subjected to a large amplitude of vibration, the front end of the warning device will fall, causing the contact surface of the arc-shaped locking block and the arc-shaped locking groove to slide and be dislocated, thereby causing the angle of the warning device to change. Therefore, the inventor proposes an anti-fatigue driving warning device based on real-time monitoring of the driver's head status to solve the above problem. Summary of the Invention
