一种车内智能防窒息系统设计

Design of an intelligent anti suffocation system in vehicle

为了进一步减小儿童被锁车内窒息而亡事件的发生几率,本文设计了一种车内智能防窒息监测与报警系统。此系统涵盖了监测、执行、报警等几大模块,在传感监测装置完成对车辆行驶状态、车内是否存在滞留人员等指标判断的基础上,当二氧化碳浓度与温度传感器监测到异常时,通过GSM模块向监护人下发预警短信、单片机控制步进电机自动开启车窗等手段,实现准确判断、实时监控、及时报警功能,从而确保儿童在危险情况下能够获救。

In order to further reduce the probability of suffocation and death of children locked in the car,an intelligent anti suffocation monitoring and alarm system in the car is designed in this paper.This system covers several modules such as monitoring,execution and alarm.Based on the judgment of the driving state of the vehicle and whether there are stranded people in the vehicle by the sensor monitoring device,when the carbon dioxide concentration and temperature sensor detect abnormalities,it can realize the functions of accurate judgment,real-time monitoring and timely alarm by sending early warning messages to the supervisor through the GSM module and controlling the stepping motor to open the window automatically by the single chip microcomputer,This ensures that children can be rescued in dangerous situations.
