Embodiment

[0029] Example: such as figure 1 , figure 2 As shown, the present invention is a watch with driver fatigue detection, including a watch case and a liquid crystal display;

[0030] The signal output terminal of the wrist pulse sensor 1 is connected to the pulse signal processing circuit 2. The pulse signal processing circuit 2 includes a signal amplifier 3, an active filter 4, and a voltage shaping circuit 5. After the pulse signal is amplified by the signal amplifier 3, the Filtering is performed in the device 4 to remove interference such as noise and harmonics. After being processed by the voltage shaping circuit 5, it is sent to the first microprocessor 6 for pulse counting; the self-learning module 7 is stored in the first microprocessor 6 for statistics, Calculate the driver’s stable pulse rate, and define the pulse rate as the normal pulse rate, and use this normal pulse rate as a reference value for judging whether it is in a fatigue state; clock module 8, providing real-t...

Abstract

The invention discloses a watch capable of detecting the fatigue of a driver, which aims to solve the technical problems of complicated equipment, deficiency of active vehicle control measures and the like existing in the prior art, has a simple structure, is convenient to use and can give an alarm for the fatigue and correspondingly control a vehicle. The watch comprises a watch shell, a liquid crystal display screen, a pulse sensor, a pulse signal processing circuit, a clock module, a wireless transmission module, a first microprocessor, a wireless receiving module and a second microprocessor.

Description

Technical field [0001] The invention relates to a driver fatigue detection technology, in particular to a watch type detection device for detecting the fatigue state of the driver. Background technique [0002] Driving fatigue refers to the imbalance of physiological function and psychological function of the driver after a long time of continuous driving, and the phenomenon of objectively decreasing driving skills. Drivers have poor or insufficient sleep quality and are prone to fatigue when driving vehicles for a long time. Driving fatigue will affect the driver's attention, feeling, perception, thinking, judgment, will, decision, and sports. If you continue to drive the vehicle after fatigue, you will feel drowsy, weak limbs, inability to concentrate, decreased judgment ability, even trance or instantaneous memory disappearance, delayed or premature action, operation pause or improper correction time and other unsafe factors. Road traffic accidents are extremely prone to occ...
