汽车防疲劳驾驶预警系统设计摘要汽车已经成为我们生活中的一种必要的代步工

Automobile anti-fatigue driving warning system design <br><br>summary <br><br>Automobile has become a necessary transportation tool in our lives, not only closely related to our lives, but also inextricably linked to our life safety. Because the tragedy caused by tired driving has seriously threatened people's lives and property, I hope my plan can reduce the chance of traffic accidents. This design is based on the AT89C2051 single-chip microcomputer fatigue driving inspection warning system. It can be used to check the fatigue status of car drivers, and the use of this system can reduce driving hazards to a certain extent. Moreover, its inspection method is non-touch, using an infrared system to check the driver's heartbeat. Then, the single chip microcomputer system determines whether it is in a state of exhaustion, displays the test results using the LCD liquid crystal display, and gives a safety prompt and issues an alarm. The system has high practicality. <br><br>Keywords: <br>Tired driving, early warning system, AT89C2051, infrared inspection, fatigue driving refers to the phenomenon that the driver's physical and psychological dysfunction and the decline of driving skills after a long continuous driving, the driver's attention, thinking, judgment, etc Have an impact and easily cause traffic accidents.
