摘  要
 隨著現(xiàn)代化建設(shè)的飛速發(fā)展以及人民生活水平的不斷提高，人們對其住宅的要求也越來越高，表現(xiàn)在不僅希望居室溫馨、舒適，而且對其安全性、智能化方面也提出了更高的要求。另一方面，隨著超大規(guī)模集成電路、通信技術(shù)、單片機技術(shù)的迅猛發(fā)展，利用單片機及其它外圍芯片實現(xiàn)自動報警己成為可能，而且是一種發(fā)展趨勢。它不僅有體積小、安裝方便、功能較齊全等優(yōu)點，而且有很高的性價比，因此應用前景廣泛。
 本文介紹了一種操作方便、運行可靠的家庭型智能報警系統(tǒng)。它用于防范盜賊入侵，可實現(xiàn)自動檢測和自動報警。自動檢測是指由各種復合式探測器或傳感器實現(xiàn)對住宅的各種模擬信號（人體發(fā)出的紅外信號、人引起的振動信號等等）進行自動監(jiān)測，復合式傳感器的應用使得系統(tǒng)可靠性更強。當傳感器檢測到異常情況，馬上產(chǎn)生一個信號給單片機。單片機根據(jù)報警信號做出報警處理。
 本論文從硬件和軟件兩方面對該系統(tǒng)進行了詳細的分析。詳細介紹了核心芯片的選型，外圍電路的連接，芯片與芯片之間的連接電路，程序設(shè)計方法和相應的軟件，并給出了關(guān)鍵軟件的程序源代碼。

Abstract
 With the rapid development of modernization and great improvement of people's living, the need of house has been changed from only the living space to multiform needs of high-quality, mufti-function safety, intelligence and so on. On the other hand, With the dramatic development of VLSI(very large-scale integrated circuit),the
telecommunication technology and MCU (micro-control unit) it is possible to set alarm automatically by micro-controller and other chips, which becomes a kind of trend. Because it is small and convenient to install and the ratio of performance and cost is high, it will have a bright future.
 A kind of easy to use, reliable intelligent safe-proof alarm system for residential area is introduced .It has the functions of theft-proof. The Infrared sensor and Vibration sensor combined are used for theft-proof so as to realize automatic detection. Multi-sensors make the least false alarm and enhance the reliability of system. When the sensors detect any off normal signal, an interrupt request is sent to the MCU. Immediately the MCU control the circuit to alarm.
 This dissertation describes the design of hardware and software of the alarm in
detail, in which selecting suitable chips, periphery circuit, chips interface, and the
methodology of program are discussed .More over, the key program is described.
