摘要

目前市場上针對一般家庭的智能防盗、防火等产品诸多，但基于遠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，非常适合一般家庭使用,并且随時可以升级。本产品采用的是以意法半导体企业生产的單片机STM32F103RBT6作為主控芯片，AT24C02作為静态存储芯片，4*4薄膜键盘和紅外热式感应作為探测器，GSM和扬声器的家庭报警模块。

伴随信息技术的发展，实現家居的信息化、网络化，是目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結合，為一款便敏小巧，低成本，适合一般室内报警的智能报警系统。本系统通過传感器获取室内人员信息，并将信号发送到單片机微处理器。系统收到报警信息後通過识别密码的方式确定目的身份，并通過蜂鸣器报警的方式警示入侵者。此外，系统配置具手机通信功能的GSM模块，能将室内安全状况第一時间发送至顾客手机终端。不仅大大提高系统安全性及智能性，也以便顾客的使用。

經测试，本系统稳定可靠，同步具有友好的人机界面，為顾客提供安全服务的同步，实現系统智能化管理。
