基于单片机的智能防酒驾装置设计

Design of Intelligent Control System Against Drunk Driving Based on Single-chip

针对酒驾醉驾引发交通事故等问题,以单片机为控制核心,选取合适的传感器、显示器件、报警及控制执行机构,研究开发了一款适用于车内车载的智能防酒驾装置,实现多点酒精浓度数据的快速获取、显示,能够报警及禁止车辆启动等功能。在完成软硬件设计后制作了样机,并进行了测试。测试结果表明,该装置测量精度高、反应灵敏、安装方便、实用性强、安全可靠、维护成本低廉,有一定应用价值。

Because drunk driving results in traffic accident,this paper takes the single-chip as control core and chooses the appropriate sensor,display device,alarm and control actuators,which are used to develop and research a kind of intelligent control system against the drunk driving.The system can be used to get and display alcohol concentration quickly and forbid vehicle operating.It completes the software and hardware design makes and tests the prototype machine.The result shows that the syetem is characteristic of high measuring precision,high response,easily installing,high safety and reliability and low maintenance costs.It is of some practical value in engineering.
