【论文】基于单片机的住宅防盗防火报警系统设计.doc

摘 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。 The main contents This paper introduces the residential intelligent burglar fire alarm system. Residential anti-theft fire alarm system is will anti-theft fire prevention function together, finish at the same time the stolen feeling and fire detection, and realize the automatic alarm function. One stolen sentiment detection by infrared detection and microwave detector constitutes double jian detector complete, and fire detection by light smoke detectors, inductance temperature probe and carbon monoxide detectors sets a composite fire detector complete. When the burglar detectors or fire detector detect danger to the microcontroller, application, again by issued interrupt microcontroller control alarm circuit, realize the automatic alarm. This system has a password recognition function, it is only through the keyboard input the correct password can open and close of the control system. The password is not the only, can modify and replacement. The system also configuration spare power and has since dropped without electricity and improve system diagnosis function, security and stability. Besides system also from two aspects of hardware and software on the anti-interference design, can make the system reliable to finish their work. The development of times, social progress and people in the pursuit of quality of life, especially in growing, not only hope to have house comfortable, warmth, and the residence of security, intelligence, etc also put forward higher request, intellig
