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
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。

Abstract
With the development of the society, The quality of people life become more And more good，Accordingly, The number of household electrical appliances And kitchen facilities also become more，So the safe hidden trouble in security family is increasing, at the same time the whole society is in transition period, the family security problem has caused the attention of people. Traditional security measures have been unable to meet the needs of modern society. Therefore, it has become a trend to the introduction of the intelligent residential district, And Security alarm has become an important part of the field and civil construction, the information And network development.
In consideration of based on the latest communications technology integrated into traditional industries, this article combination the knowledge of the micro-controller, wireless data communication, data acquisition technology. Then research and design the home security system，based on GSM module as the information transmission and STM32 micro-controller. This system consists of main controller, display module, information transmission module and alarm module, fire protection module, sound alarm module. The security system can solve the hidden danger existed in the traditional security system，make the family security more quickly, more conveniently．It is no longer depend on the cable telephone, but with the help of the most reliable and most mature GSM mobile network, use the most intuitive form of Chinese message, the alarm situation reflects to the user．This system can prevent some dangerous situations; users can control the system for protection or reconciliation by the wireless remote. The system has advantages that the user has a small cost and operating expenses.
