1、基于STM32的智能安防系统的设计 学生专业： 电子信息科学与技术 学生姓名： 王正辉 指导教师： 康辉 20摘要随着社会的发展，人们的生活质量越来越高，家用电器和厨房设施也随之增多,家庭存在的安全隐患相应增加,同时整个社会正处于转型期，家庭的安全问题也引起了人们的关注。传统的安全防范措施已无法适应现代化社会的需求。因此，将智能化引入住宅小区已成为一种趋势，并且在智能化住宅的家庭智能管理系统中，安防报警已经成为民用建筑领域，向信息化和网络化发展的一个重要组成部分。基于将最新的通信技术融合到传统产业中的考虑，本文综合了单片机、无线数据通信、数据采集等技术，研究并设计了以STM32单片机基于GSM
2、短信模块作为信息传输的家庭安防系统。此系统由主控制器、显示模块、信息传输模块和防盗模块，防火模块，声光报警模块等组成，可解决传统安防系统存在的隐患，让家庭防盗更及时、使用更方便。它不再依赖有线电话执行报警，而是借助最可靠、最成熟的GSM移动网络，以最直观的中文短消息形式，直接把报警情况反映到用户的手机屏幕上，并发出声音报警，可以防范一定的险情，用户可以通过无线遥控对该系统进行布防和解防。该系统具有用户投资小，运营费用少的优点，并且操作简单。关键词安防系统；防火；STM32；GSMAbstractWith the development of the society, The quality o
