Abstract: ：In this paper, an intelligent monitoring system of drunk driving (IMSDD) is proposed to monitor the driving system to ensure safety supervision. Alcohol sensor is employed in IMSDD to collect alcohol concentration values acquired by breath testing from the driver. Single chip microcomputer is also applied in the system to process the collected data and then control driving system. The IMSDD monitoring is implemented before driving and in driving. The alcohol testing before driving is to prevent the driver from starting a vehicle, while the testing in driving is to alarm on site and remind the driver of stopping 20 seconds later when the testing result is beyond the legal drink driving limit. Besides, the alcohol concentration is displayed in real time in IMSDD. If the testing result is over the legal drink driving limit, the GSM remote phone is also called to alarm.
