设计总说明

随着信息技术的飞速发展以及人们生活水平的大幅度提高，人们对住宅的需求已丛追求简单的生存空间向着追求质量、功能、服务等多重需求过渡。不但希望拥有舒适、温馨的栖息地，而且对安全性、智能性等方面也提出了更高要求，智能家庭住宅的安全报警系统也应运而生。
本设计所要介绍的智能家庭防盗系统，正是在智能住宅蓬勃发展的背景下为了满足用户对安全和价格的强烈要求而设计并开发的。提出一种基于公用电话网络的智能住宅安全监控系统的设计思想并加以实现。现在很多现在很多小区都安装了智能报警系统，而且大大提高了小区的安全程度，有效保证了居民的人生财产安全。由于红外线是不可见光，有很强的隐密性和保密性，因此在防盗警戒等安保装置中得到了广泛的应用。此外，在电子防盗、人体探测等领域中，被动式热释电红外探测器也以其价格低廉、技术性稳定等特点而受到广大用户和专业人士的欢迎。
本设计首先讨论了家庭住宅智能安全防范技术的国内外发展状况，并根据国外发展的趋势和我国的国情，研究并设计一种智能家庭住宅的安全报警系统，由红外探测器实现盗警信号的检测，利用成熟的微电脑技术，采用普通电话线传输报警信号并自动电话拨号报警。当探测器检测到警情的时候，就会向单片机发出中断请求，再由单片机控制电话接口电路，实现模拟摘机，通过DTMF拨号电路实现自动拨号，并由语音电路通过电话完成播放预先录制好的 语音信息，实现语音报警，来通知用户发生警情，以便让他们及时的做出相应措施。另外，本系统通过密码来识别主人身份，系统开启后只有输入正确的密码才能关闭系统。本系统还配置了备用电源以及具有掉线和断电自动诊断功能，增强了系统的安全性和稳定性。
本设计具有一定的经济性和实用性。作为智能住宅安防系统中防盗报警方面开发的一个尝试，离最后的实用化、产品化还有相当远的距离。但对后续研究开发有一定的参考意义，其随着微电子技术、自动控制技术和传感技术发展，还会得到更大的发展空间。

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.
