The invention discloses a height-adjustable direction turning device, comprising a steering unit, a steering wheel and an adjustable steering assembly, the steering wheel is arranged on the adjustable steering assembly, wherein the steering wheel includes an outer disk, an inner disk and a connection a rod, the outer disk and the inner disk are connected by a connecting rod; a locking and tracking unit is arranged in the installation groove of the inner disk; and a control unit is arranged on the inner disk and is connected with the locking and tracking unit. The present invention has reasonable design and compact structure, and can track the rotation of the driver through the set locking and tracking unit, thereby avoiding the influence of personal behavior, collection angle, environment and other conditions, so as to accurately predict the driver's fatigue state and meet the use requirements. To ensure the accurate performance of detection information.
Description
technical field [0001] The invention relates to the technical field of driving fatigue detection, in particular to a height-adjustable direction rotation device. Background technique [0002] Traffic safety involves many factors such as people, vehicles, roads and the environment. According to statistics, 25-30% of the world's annual car collisions are related to fatigue driving. The research on driving fatigue detection technology can effectively reduce and prevent the occurrence of driving accidents. At present, there are two main research methods for driving fatigue detection at home and abroad: subjective detection and objective detection. The subjective detection method mainly uses the driver's self-feedback on his fatigue state during driving. This method is convenient to implement as a research method, but it cannot reflect the driver's fatigue state in real time. Objective detection methods mainly reflect driving fatigue by measuring relevant objective parameters s...
