防幼儿误锁车内自动报警系统设计

Design of an Automatic Alarm System for Preventing Children from Accidentally Locking the Car

近年来,幼儿被误锁车内事件频发。由于夏季气温较高,阳光直射,密闭的车内温度会急剧上升,幼儿不具备自救能力,一旦被误锁车内,极易出现中暑,严重时会出现昏迷、休克甚至死亡。因此设计一套能判断幼儿被误锁车内,能自动报警提示用户,且能在车门被打开之前自动调节车内温度以保障幼儿生命安全的防幼儿误锁车内自动报警系统。将系统移植到试验车辆进行测试,测试结果表明,系统能够在锁车后自动开启,可利用重力传感器与热释电传感器判断车内幼儿遗留情况,并根据判断结果控制报警与提示模块。

In recent years,there have been frequent incidents of young children being mistakenly locked into their cars.Due to the high temperature and direct sunlight in summer,the temperature inside a closed car will sharply rise,and young children do not have the ability to save themselves.Once accidentally locked in the car,they are prone to heatstroke,and in severe cases,they may experience coma,shock,or even death.Therefore,a set of automatic alarm system is designed to prevent children from accidentally locking the car,which can automatically alert users and adjust the temperature inside the car before the door is opened to ensure the safety of children's lives.The system is transplanted to the test vehicle for testing,and the test results show that the system can automatically open after locking the car.Gravity sensors and pyroelectric sensors can be used to determine the situation of children left behind in the car,and the alarm and prompt module can be controlled based on the judgment results.
