設(shè)計(jì)總說(shuō)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(duì)住宅的需求已叢追求簡(jiǎn)單的生存空間向著追求質(zhì)量、功能、服務(wù)等多重需求過(guò)渡。不但希望擁有舒適、溫馨的棲息地，而且對(duì)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(bào)警系統(tǒng)也應(yīng)運(yùn)而生。
本設(shè)計(jì)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(duì)安全和價(jià)格的強(qiáng)烈要求而設(shè)計(jì)并開(kāi)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(jì)思想并加以實(shí)現(xiàn)?，F(xiàn)在很多現(xiàn)在很多小區(qū)都安裝了智能報(bào)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(cái)產(chǎn)安全。由于紅外線是不可見(jiàn)光，有很強(qiáng)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(cè)等領(lǐng)域中，被動(dòng)式熱釋電紅外探測(cè)器也以其價(jià)格低廉、技術(shù)性穩(wěn)定等特點(diǎn)而受到廣大用戶和專業(yè)人士的歡迎。
本設(shè)計(jì)首先討論了家庭住宅智能安全防范技術(shù)的國(guó)內(nèi)外發(fā)展?fàn)顩r，并根據(jù)國(guó)外發(fā)展的趨勢(shì)和我國(guó)的國(guó)情，研究并設(shè)計(jì)一種智能家庭住宅的安全報(bào)警系統(tǒng)，由紅外探測(cè)器實(shí)現(xiàn)盜警信號(hào)的檢測(cè)，利用成熟的微電腦技術(shù)，采用普通電話線傳輸報(bào)警信號(hào)并自動(dòng)電話撥號(hào)報(bào)警。當(dāng)探測(cè)器檢測(cè)到警情的時(shí)候，就會(huì)向單片機(jī)發(fā)出中斷請(qǐng)求，再由單片機(jī)控制電話接口電路，實(shí)現(xiàn)模擬摘機(jī)，通過(guò)DTMF撥號(hào)電路實(shí)現(xiàn)自動(dòng)撥號(hào)，并由語(yǔ)音電路通過(guò)電話完成播放預(yù)先錄制好的 語(yǔ)音信息，實(shí)現(xiàn)語(yǔ)音報(bào)警，來(lái)通知用戶發(fā)生警情，以便讓他們及時(shí)的做出相應(yīng)措施。另外，本系統(tǒng)通過(guò)密碼來(lái)識(shí)別主人身份，系統(tǒng)開(kāi)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(dòng)診斷功能，增強(qiáng)了系統(tǒng)的安全性和穩(wěn)定性。
本設(shè)計(jì)具有一定的經(jīng)濟(jì)性和實(shí)用性。作為智能住宅安防系統(tǒng)中防盜報(bào)警方面開(kāi)發(fā)的一個(gè)嘗試，離最后的實(shí)用化、產(chǎn)品化還有相當(dāng)遠(yuǎn)的距離。但對(duì)后續(xù)研究開(kāi)發(fā)有一定的參考意義，其隨著微電子技術(shù)、自動(dòng)控制技術(shù)和傳感技術(shù)發(fā)展，還會(huì)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.
