摘 要

目前市场上针对普通家庭的智能防盗、防火等产品很多，但基于远程报警系统的智能家居产品价格不菲。本次设计的基于STM32的智能家居报警系统实用性非常强，设计成本低廉，非常适合普通家庭使用,而且随时可以升级。本产品采用的是以意法半导体公司生产的单片机STM32F103RBT6作为主控芯片，AT24C02作为静态存储芯片，4*4 薄膜键盘和红外热式感应作为探测器，GSM和扬声器的家庭报警模块。

随着信息技术的发展，实现家居的信息化、网络化，是当前智能家居系统发展的新趋势。本设计将通信技术与防盗系统紧密结合，为一款便敏小巧，低成本，适合普通室内报警的智能报警系统。本系统通过传感器获取室内人员信息，并将信号发送到单片机微处理器。系统收到报警信息后通过辨认密码的方式确定目标身份，并通过蜂鸣器报警的方式警示入侵者。另外，系统配备具手机通信功能的GSM模块，能将室内安全状况第一时间发送至用户手机终端。不仅大大提高系统安全性及智能性，也方便用户的使用。

经测试，本系统稳定可靠，同时具有友好的人机界面，为用户提供安全服务的同时，实现系统智能化管理。
