Abstract
The article design the hardware system scheme using STM32F407 as the control core circuit, and designed the software structure of the system and application layer multi task and priority based on transplanted μC/OS operating system. Aimed at that the traditional drunk driving detection system has low sensitivity and unable to distinguish diffuse alcohol signal interference. For accurate identification of pilot and crew alcohol concentration, the paper puts forward a driving intelligent identification wine system based on embeddedμC/OS-II. The experimental results show that the detection sensitivity of the system has high accuracy rate, effectively prevent the purpose for the prevention of drunk driving, drunk driving has very good practical value.
