Design of Vehicle-based Driving Monitoring System Based on STM32

With the rapid development of science and technology, electrical engineering, as the core and key disciplines in the field of modern technology, is constantly promoting the innovation and progress of various industries. Its widespread application has profoundly changed human life and work model. In the field of transportation safety, the application of electrical engineering technology is particularly critical, especially for the solution to prevent drunk driving. This article designs a car-car alcohol-driving monitoring system based on STM32 microcontroller. This system integrates sensor technology, signal processing technology, microcontroller technology, and wireless communication technology (GSM) to achieve real-time real-time concentration of driver's alcohol concentration Detection and monitoring can effectively prevent the occurrence of alcohol-driving behavior. Through many actual on-site tests, the results show that the equipment has an effective prevention effect on drunk driving, providing active protection guarantee for traffic safety, and has certain practical value for preventing drunk driving.
