摘 要:近几年随着汽车的大众化,越来越多的儿童由于被困车内时间过长导致丧生。为防止这一悲剧的发生,小组决定采用 51 单片机设计一款针对汽车内滞留儿童安全的防护系统。该系统能够利用压力感应器、红外线传感器等人体感应器探测是否有孩子的存在。在确定有儿童的存在时通过温度传感器与二氧化碳传感器检测车内是否有对孩子产生窒息的风险。当出现风险时,发出警报提醒路人同时向车主发送短信。

Abstract: In recent years, with the popularization of cars, more and more children have been trapped in cars for a long time, resulting in death. In order to prevent the occurrence of tragedy, the group decides to use 51 Single-Chip Microcomputer to design a safety protection system for detained children staying in the car. The system can detect the presence of children by using pressure sensors, infrared sensors and other human sensors. When determining the presence of children, the temperature sensor and carbon dioxide sensor are used to detect whether there is a risk of suffocation to children in the car. When the risk happens, it will sound the alarm to alert passers-by and send text messages to the car owner.
Keywords: detained children; Single-Chip Microcomputer; sensor; alarm; GSM communication
