摘要
为有效预防酒后驾驶,应用多个MQ-3酒精传感器和低功耗单片机,采用贝叶斯估计的数据融和方法设计出手持式防酒后驾驶系统。系统检测到驾驶员血液中酒精浓度超过20 mg/100 mL时,启动汽车闭锁控制使其无法启动,通过GPS模块定位汽车位置,使用GSM模块的短信功能将驾驶员的醉酒程度和汽车位置信息发送给系统预设联系人。该系统提高了检测结果的准确性和可靠性,功耗低,方便携带,对预防酒后驾车具有很好的效果。
In order to effectively prevent drink driving,multiple MQ- 3 alcohol sensors and low-power microcontroller are applied and the method of data fusion based on Bayes estimation is used to design of the hand-held alcohol detect system. When the system detects the alcohol concentration of driver＇s blood above 20 mg /100 mL,starting the car latch control makes it do not start. Positioning car location by GPS module,the degree of intoxication and car＇s location information is sent to the default contact person of the system by using messaging function of the GSM module. The system improves the accuracy and reliability of test results,low-power consumption,easy to carry and has a good effect on the prevention of drunk driving.
