Watch capable of continuously monitoring heart rate and preventing sleepiness

Abstract

The invention relates to a watch capable of continuously monitoring heart rate and preventing sleepiness. The watch comprises a watch band, a shell with a display screen, a bottom cover, buttons and a clock mechanism mounted in the shell, wherein the clock mechanism comprises a photoelectric detection module, a low-frequency electric pulse module, a Bluetooth module, a central processing unit, a periphery management circuit, a rechargeable battery, a power supply management circuit and a vibration prompt device; the inner side of the shell is provided with a detection window, the photoelectric detection module comprises an LED light source capable of emitting light with the wavelengths of 630 nanometers and 940 nanometers, a photosensitive device and a trans-resistance amplifier, and the pulse oximeter signal which is reflected by a human body and received by the photosensitive device is amplified by the trans-resistance amplifier and output to the central processing unit. The watch has the advantages that the parameters of the human body are set through an intelligent terminal or a smart phone, whether a driver is in a fatigue state or not is detected by the pulse oximeter signal reflected by the human body, the vibration prompt device is driven to provide vibration prompt, and the low-frequency electric pulse module can be driven at the same time to generate low-frequency pulses to stimulate the human body.

Description

technical field [0001] The invention relates to the technical field of driver safety driving detection, in particular to an anti-drowsiness meter for continuous monitoring of heart rate. Background technique [0002] Traffic accidents are one of the serious social problems faced by countries all over the world. It has been recognized as the largest public hazard that endangers human life and safety in the world today. At least 500,000 people die due to traffic accidents every year. Statistics on traffic accidents in European and American countries Analysis shows that 80% to 90% of traffic accidents are caused by human factors. According to the statistics of the National Highway Traffic Safety Administration of the United States, on the highways of the United States, about 100,000 accidents are caused every year due to drivers falling asleep while driving. There are about 1,500 traffic accidents that directly lead to death, and 7.11 million cases that cause personal injury. The...

Problems solved by technology

[0004] For this reason, some patents that identify whether the driver is in a fatigue state by collecting the driver's facial image or the blink frequency or the degree of eye opening and closing, and then process it, are proposed, typically as CN101565036B, CN201578257, CN203480645, etc., existing The technology has the following deficiencies: since the driver is not in a relatively completely static state relative to the image acquisition equipment, it is difficult to achieve a high accuracy rate through image recognition and processing, and needs to be improved
