Embodiment Construction

[0013] Fatigue driving warning system of the present invention, as figure 1 As shown, it includes a camera installed in the car and a detection control device. The detection control device is provided with a microprocessor and an alarm speaker connected to the microprocessor. The camera is connected to the microprocessor through a communication line, and the microprocessor Connected with the car central control system, the car central control system can be used to control the braking device of the car.

[0014] The camera captures the image of the driver's face, and sends the image to the microprocessor for analysis and processing; the microprocessor analyzes the image to obtain the movement information of the driver's eyes, and the microprocessor then analyzes the movement information of the driver's eyes Analyze to get the driver's blinking frequency and real-time eye opening distance; the microprocessor compares the driver's blinking frequency and real-time eye opening dist...

Abstract

A fatigue driving alarm system comprises a camera and a detection control device which are installed in a vehicle. A microprocessor and an alarm loudspeaker connected with the microprocessor are arranged in the detection control device. The camera and the microprocessor are connected through a communication line. The microprocessor is connected with a vehicle central control system. The vehicle central control system can be used for controlling a brake device of the vehicle. The current state of a driver can be detected by the fatigue driving alarm system according to the motion of the eyes of the driver, the detection control device does not need to make contact with the head of the driver, the attention of the driver is not influenced, the comfort of the driver in the driving process is guaranteed, and the safety of the driver in the driving process is guaranteed.

Description

technical field [0001] The invention relates to an automobile auxiliary device, in particular to a fatigue driving alarm system and an alarm method thereof. Background technique [0002] my country's transportation industry is developing rapidly, and the subsequent road traffic accidents are also on the rise. According to the data of the transportation department, the proportion of traffic accidents caused by fatigue driving is very large, accounting for a larger proportion of serious traffic accidents. Fatigue Driving has become the main hidden danger of traffic accidents and has attracted people's attention. For fatigue driving, many detection devices for fatigue driving have also appeared, but the detection devices currently used mainly detect the posture of the driver's head to judge fatigue driving. The detection device needs to be in contact with the driver's head, which affects the driver's attention, makes the driver feel uncomfortable, accelerates the speed of driver ...
