精品 摘 要 现今市场上虽有各种名目繁多的报警装置，但多由于可靠性较差、功能单一或造价较高而难于普及，因此如何开发和利用单片机来构成家庭、仓库、银行等地的安全防范系统，己成为众商家关注的焦点。 本文首先讨论了智能家居在国内外发展概况，并根据国内外的发展情况和趋势，研究并设计了该无线控制的智能家居防盗报警系统。本设计从硬件设计和软件构成介绍一种单片机控制的与公共电话网连接，可以进行远程报警，以满足人们对家庭安全情况的及时了解、实时信息处理和有效控制的迫切需要的智能远程电话语音报警系统。该系统由用户通过键盘输入五组电话号码作为语音报警对象，预录可长达 20S的语音信号说明警情发生的地点，设防状态下即可实现多个设防点的信号检测并迅速进入自动报警状态，是一种适合于家庭、办公室和的仓库等处可靠性较好的安全防范装置。 本智能化报警系统利用无线传输技术手段，克服了有线传输技术的缺陷，采用PT2262/2272编解码集成电路、自动拨号系统、语音电路系统等配套互动，实现无线报警控制。 关键词：DTMF；信号检测；智能住宅；语音报警  Abstract Although there are kinds of alarm devices in markets, it is still hard to get dissemination because of low liability and function. Therefore, how to explore and make use SCM to setup a safety defense system for home, warehouse and bank use has become a focus. From the design of hardware and software, we can make a connection between a specific type of SCM and the public phone net to setup a distant alarm system for the demand of safety and efficient data processing and control. The system user can input 5 groups of phone number as the alarm objects and pre-record voice signals lasting for 20S showing the alarm site. The system can get signals from multi-locations and get into automatic alarm status under defense function. Therefore, it is suitable for home, office and warehouse use. The development of intellectual home-set abroad is discussed in the first part and one wireless alarm system is designed and introduced. The alarm system adopts wireless transfer technique to avoid the limitation of wire transfer technique. PT2262/2272 decoding circuit, auto-dial and voice circuit are adopted also for wireless alarm control purpose.
