随着社会经济的告诉发展,拥有私家车的家庭越来越多,继而发生把幼儿遗忘在车内导致其受伤或者死亡的案例越来越多,例如:2007年8月8日7时许 因负责接送的两名幼儿园老师和校车司机疏忽大意,济南一幼儿园5岁幼儿被遗忘在校车内,直到当天下午5时20分才被发现在车内死亡,后被法医鉴定为中暑死亡。因此,有必要设计一款在车内检测是否有幼儿且可以报警的装置防范这样的悲剧再次发生。基于简便,易安装的特点以及使用要求,设计一款基于单片机的电子检测系统。

abstract

With the social and economic development told, private car ownership more and more families, and subsequent to the forgotten children in the car leads to injury or death of more and more cases, for example: August 8, 2007, 7 pm due responsible for transfers of two kindergarten teachers and school bus driver negligence, Jinan, a 5-year-old nursery school children were forgotten in the car until the day of 17:20 was discovered dead in the car, after the forensic identification of heat stroke and death. Therefore, it is necessary to design the car to detect whether there is a tragedy like this child and alarm devices can prevent from happening again. Based on simple, easy installation features and requirements, design a microcontroller-based electronic detection system.

本文设计的高精度电子称主要以AT89C51单片机为核心,通过Proteus软件和KEIL软件实现了对报警装置的功能的设计。主要分为一下几个模块个模块:GSM短信发送模块、单片机处理模块AT89C51、人体红外检测模块软件驱动模块KEIL程序。

基本设计思路

通过红外线检测是否有人,然后通过发送数据告诉单片机,单片机经过处理再控制GSM模块发送短信给事主。
