Description

Technical field [0001] The present invention relates to an early warning system, in particular to a fatigue work online early warning system and an early warning method thereof for online identification and warning of fatigue tendencies and fatigue states of users during work. Background technique [0002] Persons on duty in important positions often experience mental fatigue and decreased concentration of energy during long work periods, especially at night. This will lead to dizziness and nap symptoms, resulting in decision-making errors, perceptual errors and operating errors. Decision-making errors are mainly inaccurate predictions and judgment errors. Perceptual errors include negligence, trance, improper attention, and decreased vision. Operation errors are mainly inaccurate actions. Behavioral errors caused by these fatigue are an important cause of work accidents. According to statistics, among motor vehicle traffic accidents that cause huge loss of life and property to t...
