Design of a Vehicle Fatigue Driving Detection System Based on Multiple Signals

Abstract

In recent years, traffic accidents have occurred frequently, and most of them are related to the level of fatigue of drivers. In order to avoid the dangers of fatigue driving, this article judges whether the driver is in a fatigued state by analyzing the changes in pressure, angle, and distance during driving, so as to remind the driver to reduce the probability of accidents. In terms of hardware, we use the AT89C51 microcontroller as the main control unit, and configure infrared sensors, ultrasonic sensors, angular velocity sensors, and pressure sensors to detect the physical state of the driver. In terms of software, we use C language to write code and optimize and compile it through Keil software. The system can display the detected data on the LCD display screen and send an alarm at the same time.
