摘 要
随着社会经济的飞速发展和人民生活水平的不断提高，人们对其住宅的要求也越来越高，表现在不仅希望拥有舒适、温馨的住所，而且对安全性、智能性等方面也提出了更高的要求，智能住宅的安全防范系统也应运而生。现在很多小区都安装了智能报警系统，因而大大提高了小区的安全程度，有效保证了居民的人身财产安全。由于红外线是不可见光，有很强的隐蔽性和保密性，因此在防盗、警戒等安保装置中得到了广泛的应用。
此文首先讨论了智能住宅安全防范技术的国内外发展概况，并根据国外发展的趋势和我国的国情，研究并设计了一种智能住宅的安全防范报警系统，由红外探测器实现盗警信号的检测，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。

Abstract
With the rapidly development of socio-economic and constantly improvement of people‘s living standard, people have more and more residential demand, reflected in not only want to have comfortable, warm shelter, but also made more High demand for security, intelligence and other performance, smart home security system came to begin with it. Now many of the community are installed intelligence alarm system, thus the community safety is greatly improved, effective inhence the residents’ personal and property safety. Because infrared is not visible, have a strong hidden nature and confidentiality, so it has widely used in anti-theft, and other security warning devices .
In this text, the development survey of security keeping away technology of Smart Home in the world is debated. According to the developmental direction of the technology overseas and the situations of our countries, we have researched and designed a kind of intelligent alarm system for SmartHome. It has the function of theft-proof, performing automatic detection 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-p 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 time.
Key words：Security keeping away; Intelligent alarm system; MCU controlling; DTMF dial-up
