Abstract

一种酒精检测报警装置，用来限制一些汽车驾驶员酒后开车，或者用来供给交通管理人员在交通现场检测驾驶员是否酒后开车，具有很高的实用性。

Description

一种酒精检测报警装置
技术领域
本发明涉及一种酒精检测报警装置。
背景技术
随着居民生活的提高，好多百姓家庭添置了小汽车，节假日之时，亲朋好友相互走访，并高兴之时，举杯相互祝贺。有些汽车驾驶员，不小心把自己喝醉了，还开车上路。
发明内容
本发明一种酒精检测报警装置，用来限制一些汽车驾驶员酒后开车，或者用来供给交通管理人员在交通现场检测驾驶员是否酒后开车，具有很高的实用性。
一种酒精检测报警装置，其电路组成由电源电路、酒精检测电路、电压比较电路和发光显示电路组成。所述电源电路选用约4V直流电源和滤波电容器C组成；所述酒精检测电路由酒精气敏传感器V、电阻R1、R2发光二极管D1(选用黄颜色)和灵敏度调节电阻R3组成；所述电压比较电路由IC及外围元件组成；所述发光显示电路由两种不同颜色的发光二极管组成。
附图说明
图1是一种酒精检测报警装置的电路原理图。
具体实施方式
如图1所示，电源电路有滤波电容C，滤除开通电源时的冲击电流干扰波，使输入电源平稳的送到酒精检测电路的气敏传感器V；所述的气敏传感器V，其输出端通过可调分压电阻R3，将信号送至比较器电路IC。
当未检测到酒精气味时，则V输出电压低于设定值V＝VCCR5(R4+R5)，根据电压比较器IC原理可知，此时上比较器输出端“1”脚输出低电平，三极管T1截止，发光二极管D2(选用红颜色)不发光；而下比较器输出端“7”脚输出高于设定值电压，D3(选用绿颜色)发光，表示驾驶员未喝酒。
当酒精气敏传感器V检测到酒精气味时，其输出端电位会随着检测到的酒精浓度增加而上升，当R3点电压上升到设定值时，根据电压比较器原理可知，此时上比较器输出端“1”脚输出高电平，驱动发光二极管D2亮，表示驾驶员饮酒超过标准，应强制其停止开车。
