A fatigue alarm device

Abstract

The invention discloses a fatigue alarming device which comprises a fatigue detector, a loudspeaker, a light emitting element and a control element. The fatigue alarming device is placed at a positionwhere the fatigue detector can capture at least one of a facial image and a physiological signal. The fatigue detector is used for determining at least one absent-minded signal according to the facial image or the physiological signal, and electrically connected with the control element. The control element is electrically connected with the loudspeaker and the light emitting element, and startsa warning program, including enabling the light emitting element to emit in short time and the loudspeaker to make a short sound for the first time, and after resting a certain time, the enabling theloudspeaker to make a short sound for the second time, by the absent-minded signal. The time difference between the first sound and the second sound of the loudspeaker is 50-150 milliseconds to matchthe alpha cranial nerve oscillation phase, and finally the human brain generates the illusion of the second flash.

Description

technical field [0001] The invention relates to a fatigue alarm device, in particular to a fatigue alarm device utilizing a self-awakening mechanism. Background technique [0002] According to the survey of 47 million adults by the National Sleep Foundation (NSF) in the United States in 2002, more than half of them had felt drowsy while driving in the past year, and 17% even knew that they were sleepy. Fall asleep while driving. Coincidentally, the National Highway Traffic Safety Administration (NHTSA) of the United States also statistics that in 2014 alone, 846 people died due to fatigue driving, accounting for 2.6% of all fatal car accidents. From 2005 to 2009, there were about 83,000 car accidents related to drowsy driving in the United States each year, of which 886 people were killed and 37,000 people were injured. What's more dangerous is that many drivers never realize that they have briefly lost their minds or dozed off briefly. [0003] In this regard, U.S. Paten...

Problems solved by technology

[0006] However, in practical applications, due to the extremely weak voltage of brain waves, the measurement of brain waves can only be carried out by means of electrodes attached to the scalp, for example: the brain wave helmet disclosed in Taiwan Patent No. I488588, the user himself Installation is prone to signal instability

In addition, monotonous alarm methods (such as beeps, flashes or vibrations) have no real wake-up effect for people who are about to fall asleep
