1、 毕业论文（设计） 题 目：基于单片机的住宅防盗防火报警系统设计 2 摘摘 要要 本文介绍了住宅智能化中的防盗防火报警系统。住宅防盗防火报警系统是 将防盗防火功能结合到一起，同时完成盗情和火情的检测，并且实现自动报警 功能。其中盗情检测由红外探测器与微波探测器构成的双鉴探测器完成，而火 情检测由光电感烟探测器，温度探测器和一氧化碳探测器集为一体的复合式火 灾探测器完成。当防盗探测器或防火探测器检测到险情的时候，向单片机发出 中断申请，再由单片机控制报警电路，实现自动报警。 本系统具有密码识别功能，只有通过键盘输入正确的密码才能控制系统的 开闭。密码并不是唯一的，可以修改以及更换。本系统还配置了
2、备用电源以及 具有断电和掉线自诊断功能，增强了系统的安全性和稳定性。此外系统还从硬 件和软件两方面进行了抗干扰设计， 能够让系统可靠的完成工作。 时代在发展， 社会在进步，人们对生活质量的追求也在日益增长，特别是住宅方面，不仅希 望拥有舒适、温馨的住所，而且对安全性、智能性等方面也提出了更高的要求， 智能住宅的安全防范系统也应运而生。现在很多小区都安装了智能报警系统， 因而大大提高了住宅的安全程度，有效保证了居民的人身财产安全。 关键词: 防盗防火；传感器；单片机控制；智能报警系统。 3 The main contents This paper introduces the residenti
