摘 要
在社會信息化進程日益發展的今天，信息技術已滲透到人類生存、活動的各個領域，在建筑領域，人們的現代生活、工作對居住和辦公的建筑環境不僅要求舒適健康、安全可靠、高效便利，同時還要適應信息化社會運用科技手段和設備的要求。因此，將智能化引入住宅小區已成為一種趨勢，并且在智能化住宅的家庭智能管理系統中對防火防盜報警進行監控已經成為民用建筑領域向信息化和網絡化發展的一個重要組成部分。
本文介紹了智能化住宅中的防盜防火報警系統。采用MC-51系列80C51為核心單片機控制，集智能化防盜防火功能于一體住宅報警系統，可實現自動檢測與自動電話撥號報警。自動檢測是指由紅外探測與微波探測器構成的探測器實現智能檢測，同時由溫度探測器和光電感煙探測器集為一體的復合式火災探測器完成火情檢測。多傳感器的應用實現了低誤報率，增強了系統可靠性。自動電話撥號報警是指通過電話網絡自動向相關部門發出語音求救信號。當防盜、防火探測器檢測到險情的時候，向單片機發出中斷申請，再由單片機控制電話接口電路，實現模擬摘機，根據險情類別，自動撥打相關部門的電話號碼如小區管理中心電話。

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
