With the frequent occurrence of drunk driving accidents,the on-board drunk driving monitoring sys-tem has become a core auxiliary driving unit in modern vehicles.This article presents a design of an embedded drunk driving assistance system,with the STM32 as the main control module,the alcohol sensor and heart rate sen-sor module as the detection module,and Linux as the kernel module.Relevant control system and Linux on-board display system programs are developed to achieve real-time detection of the driver's alcohol level and heart rate.Through testing,it has been proven that this design can realize functions such as driver alcohol and heart rate warn-ing,as well as real-time display.The system is stable,easy to operate,and features easy integration and portability.
