摘要
汽车车内由于CO导致的意外安全事故常常被忽略。汽车发动机和空调在运行过程中产生的CO进入车内,极易被忽视而诱发中毒的事故。利用单片机传感器技术设计一种汽车车内CO浓度监控系统,当车内CO浓度达到200 ppm时系统发出第一次报警,当车内CO浓度达到300 ppm,系统发出第二次报警提示,并开启天窗通风,保证车内人员安全。
Unexpected accidents because of carbon monoxide entering interior of the car is always underestimated. Carbon monoxide produced by engine and air conditioner of the ear may enter the car and easily be ignored. That can cause carbon monoxide poisoning accidents. In this article, a carbon monoxide monito6ng system is designed using MCU sensor technology to evaluate interior environment of automobiles. The system will alarm for the first time when the level of carbon monoxide reaches 200 ppm. The carbon monoxide concentration reaching 300 ppm will trigger last alarm, in addition, the sunroof will be opened controlled by this system to ensure lives safety staying in the car.
