资料介绍

针对酒后驾车导致交通事故频繁发生的现象,设计了一种驾驶员酒精超标测控电路。该电路由酒气检测、模数转换、单片机最小系统、LCD显示、声光报警、继电器、电源等电路组成。软件用C语言编程,在keil环境中编译。硬件电路在PROTEOUS环境中仿真,通过后将下栽程序的单片机和其它有关元器件焊接在PCB板上,上电,酒气检测电路可检测酒精浓度,可语音播报浓度未超标、偏高和超标,液晶屏可显示酒精浓度,当酒精传感器检测的酒精浓度超标时,该电路可自动切断汽车点火系统电源,使汽车无法启动。

Aimed at the phenomenon of traffic accidents caused frequently by drunken driving , a measuring and controlling circuit for exceeding the driver alcohol standard is designed. The circuit is composed of alcohol gas detection circuit , analog-to-digital converter, the smallest MCU system, LCD indicator, sound and light alarm, relay, power supply circuit etc.. It is programmed with C language software and compiled in keil environment . The hardware circuit is simulated in the PROTEOUS environment successfully, The MCU downloaded program and other related components are welded on the PCB board. Power, the alcohol gas de- tection circuit can be detected by the alcohol sensor. Concentration (below, average an...
