摘 要
在社会信息化进程日益发展的今天，信息技术已渗透到人类生存、活动的各个领域，在建筑领域，人们的现代生活、工作对居住和办公的建筑环境不仅要求舒适健康、安全可靠、高效便利，同时还要适应信息化社会运用科技手段和设备的要求。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对防火防盗报警进行监控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。
本文介绍了智能化住宅中的防盗防火报警系统。采用MC-51系列80C51为核心单片机控制，集智能化防盗防火功能于一体住宅报警系统，可实现自动检测与自动电话拨号报警。自动检测是指由红外探测与微波探测器构成的探测器实现智能检测，同时由温度探测器和光电感烟探测器集为一体的复合式火灾探测器完成火情检测。多传感器的应用实现了低误报率，增强了系统可靠性。自动电话拨号报警是指通过电话网络自动向相关部门发出语音求救信号。当防盗、防火探测器检测到险情的时候，向单片机发出中断申请，再由单片机控制电话接口电路，实现模拟摘机，根据险情类别，自动拨打相关部门的电话号码如小区管理中心电话。

Abstract
Social informatization a growing process today, permeate a information technology application to the survival of mankind, in all areas of activity in the construction field, people's modern life and work of the residential and office buildings require comfort not only the environment healthy, safe, reliable, efficient Convenient, but also adapt to the information society, use of technology tools and equipment requirements. Therefore, the introduction of intelligent residential quarters have become a trend, and intelligent residential households in the intelligent management system to monitor anti-theft alarm fire has become the field of civil construction to information technology and network development of an important component.
 This text has designed a kind of intellectual burglar alarming system of residential building of housing district. It introduced the details of design method and function that can realize of this system in the article, which has explained the operation principle, the design thought of hardware and software and course of realizing in detail of this warning system. This system adopts the intellectual house where the nodal controller that one-chip computer AT89S51 realizes is suitable for the low cost. Design and include with the peripheral circuit that AT89S51 carries on for the master controller: power circuit design, warning circuit design, keyboard, display interface design, data collecting system etc.. I adopted fingerprint recognition sensor, bludgon sensor and heat into clear up electricity infrared sensor which made the system had large some measure the function to come true especially in data collecting system, and enable the controller to also design the communication of principal and subordinate machine in the system to be measured touringly by the check pointing, which makes the guarding against theft of the residential building of the district report to the police and achieve reunification and control and manage, and concentrated on reporting to the police and offering many kinds of protection for guarding against theft in the house, which makes the family to feel safer.
 
 Key words： Smart alarm system; anti-theft fire; automatic dial-up; data communications
