設(shè)計總說明

隨著信息技術(shù)的飛速發(fā)展以及人們生活水平的大幅度提高，人們對住宅的需求已叢追求簡單的生存空間向著追求質(zhì)量、功能、服務(wù)等多重需求過渡。不但希望擁有舒適、溫馨的棲息地，而且對安全性、智能性等方面也提出了更高要求，智能家庭住宅的安全報警系統(tǒng)也應(yīng)運而生。
本設(shè)計所要介紹的智能家庭防盜系統(tǒng)，正是在智能住宅蓬勃發(fā)展的背景下為了滿足用戶對安全和價格的強烈要求而設(shè)計并開發(fā)的。提出一種基于公用電話網(wǎng)絡(luò)的智能住宅安全監(jiān)控系統(tǒng)的設(shè)計思想并加以實現(xiàn)?，F(xiàn)在很多現(xiàn)在很多小區(qū)都安裝了智能報警系統(tǒng)，而且大大提高了小區(qū)的安全程度，有效保證了居民的人生財產(chǎn)安全。由于紅外線是不可見光，有很強的隱密性和保密性，因此在防盜警戒等安保裝置中得到了廣泛的應(yīng)用。此外，在電子防盜、人體探測等領(lǐng)域中，被動式熱釋電紅外探測器也以其價格低廉、技術(shù)性穩(wěn)定等特點而受到廣大用戶和專業(yè)人士的歡迎。
本設(shè)計首先討論了家庭住宅智能安全防范技術(shù)的國內(nèi)外發(fā)展狀況，并根據(jù)國外發(fā)展的趨勢和我國的國情，研究并設(shè)計一種智能家庭住宅的安全報警系統(tǒng)，由紅外探測器實現(xiàn)盜警信號的檢測，利用成熟的微電腦技術(shù)，采用普通電話線傳輸報警信號并自動電話撥號報警。當探測器檢測到警情的時候，就會向單片機發(fā)出中斷請求，再由單片機控制電話接口電路，實現(xiàn)模擬摘機，通過DTMF撥號電路實現(xiàn)自動撥號，并由語音電路通過電話完成播放預先錄制好的 語音信息，實現(xiàn)語音報警，來通知用戶發(fā)生警情，以便讓他們及時的做出相應(yīng)措施。另外，本系統(tǒng)通過密碼來識別主人身份，系統(tǒng)開啟后只有輸入正確的密碼才能關(guān)閉系統(tǒng)。本系統(tǒng)還配置了備用電源以及具有掉線和斷電自動診斷功能，增強了系統(tǒng)的安全性和穩(wěn)定性。
本設(shè)計具有一定的經(jīng)濟性和實用性。作為智能住宅安防系統(tǒng)中防盜報警方面開發(fā)的一個嘗試，離最后的實用化、產(chǎn)品化還有相當遠的距離。但對后續(xù)研究開發(fā)有一定的參考意義，其隨著微電子技術(shù)、自動控制技術(shù)和傳感技術(shù)發(fā)展，還會得到更大的發(fā)展空間。

INTRODUCTION

With the tapid development of communication technique and great improvement of standard of people’s living,the need of house has been changed from only the living space to multiform needs of quality,function,service, and so on. Not only want have a warm and comfortable house, but also want to have a better security and intelligence residence. The security keeping away system of Smarthome is emerged as the times required.
This design introduce about the intelligent family alarm system and is precisely to satisfy the under the intelligent housing vigorous development background designs to the security and the price intense request.It proposed that one kind and realizes based on the public telephone network's intelligent housing safe supervisory system's design concept. Now many plots have installed the intelligence alarm system and enhanced the safety rate greatly, effective guarantee resident's life property safety.
In this design, the development survey of security keeping away technology of  Smarthome in the world is debated.According to the developemental direction of the technology overseas and the situations of our countries, we have researched a kind of intelligent alarm system for SmartHome.It has the function of theft-proof, performing automatic detection wth the mature microcomputer technology, uses the ordinary telephone line transmission alarm and automatic dial. Pyroelectric infrared sensor is used for theft-proof so as to realize automatic detection.It is designed to make the least fail to alarm and false alarm and enhance the reliability of the system. When detector has detected any abnormality signals,an interrupt request will be sent to the MCU. Next the MCU control the interface circuit of telephone to accomplish simulated off-hook,then auto-dial by dial-up circuit of DTMF,and play the phonetic information which has been recorded beforehand by phonetic circuit, to tell the user of the emergency which has occurred, so that they can take corresponding step on tim.In addition, the system discerns the master by the secret bode,only imputed correct secret code,could system be closed..In order to buildup the systemic security and stability, inspect whether the wire and the power break or not.
This system design has some definite practicability. An attempt which the security warning aspect develops as the intelligent housing peaceful against system, to the final practical application, the production also has the quite far distance. As far as research and exploitation later,this has some definte referenced and Along with microelectronic technology, automatic control technology and sensing technological development, will also obtain the bigger development opportunities.
