Smart lighting system for fatigue driving warning system

Abstract

The invention discloses an intelligent lighting system for a fatigue driving early-warning system. The two sides of a camera of the fatigue driving early-warning system are respectively provided with a 850 nm infrared lamp and a 940 nm infrared lamp. The camera is provided with an infrared optical filter. The 850 nm infrared lamp and the 940 nm infrared lamp are connected with a control circuit. The control circuit is connected with a photosensitive sensor. According to the technical scheme of the invention, the illumination is realized by the large-power 850 nm infrared lamp in the daytime. Based on the near-infrared imaging process, the fatigue detection problem of a driver when wearing a pair of glasses that reflect the light or wearing a pair of sunglasses can be solved. At night, the illumination is realized by the 940 nm infrared lamp, so that the infrared exposure phenomenon is avoided. Therefore, the driver is prevented form being interfered.

Description

Technical field [0001] The invention relates to a fatigue driving early warning system, in particular to an intelligent lighting system used for the fatigue driving early warning system. Background technique [0002] Fatigue driving is one of the important causes of traffic accidents. When the driver is fatigued, his ability to perceive the surrounding environment, the ability to judge the situation, and the ability to manipulate the vehicle are greatly reduced, making it extremely prone to traffic accidents. According to the statistics of the National Highway Traffic Safety Administration, on American highways, there are about 100,000 traffic accidents due to driver fatigue every year, about 1,500 directly cause deaths, and 7.11 million cause injuries. The situation in Europe Also roughly the same. In China, according to the statistics of the Ministry of Communications of China, more than 20% of my country's car accidents are caused by fatigue driving, causing serious casualti...

Problems solved by technology

[0004] (1) The infrared lamps only work at night, and the infrared lamps are all illuminated by a near-infrared light source with a central emission wavelength of 850nm. The 850nm near-infrared light source has "red exposure" "The problem is that our human eyes can see the dazzling red light emitted by the light source in the dark environment at night, which greatly disturbs the driver.

[0005] (2) The infrared light does not work during the day. When the driver wears glasses that reflect light or the driver wears sunglasses, the system cannot detect the driver's eye movements, so it cannot Judging the driver's fatigue state
