摘要：俗话说：安居乐业。着社会进步和经济的发展，人们对住宅的舒适性和安全性等要求也与日俱增。电子信息技术的飞速发展让住宅安全系统智能化，也让住宅变得更安全更温馨。
本文设计一种运行可靠、自动化程度高的防盗、防火报警系统。住宅安全事件多发生在居民外出或者睡觉等无意识情况下，再加上我国一户多房众多，许多无人看管的住宅安全无法保障。如果我们可以发明一种防火防盗设备，让它的主要工作是检测与报警，也可通过手机短信等方式通知居民和保安，甚至通过物联网进行更加全面的自动化安全保护，这样居民的人生财产安全将会得到更好的保护。5101
该系统主要分三个部分，即：热释电传感器、CO传感器检测模块；AT89S51单片机处理模块；住宅警报灯警笛模块以及短息报警通知模块。
系统精简而可靠，扩展性强，适用于住宅、仓库等室内环境。而且价格低廉，能耗低，是符合我国现状的一套新型防盗、防火报警系统。

A design of thiefproof and fireproof alam system
Abstract：As the saying goes: live and work in peace. With social progress and economic development, people's demand for residential comfort and safety also grow with each passing day. The rapid development of electronic information technology makes residential security system be intelligent, also let the house become safer and more comfortable.
In this paper, a design of reliable operation, high degree of automation of the thiefproof and fireproof alarm system. Residential security incidents occurred in the residents are out or asleep, unconscious situation, coupled with some Chinese family more than one house, many unattended residential security can not be guaranteed. If we can invent a fire alarm equipment, make its main work is detection and alarm, also can through the mobile phone text messages to  
inform residents and security, even through a IOT automated security more comprehensive protection, so that the residents of the life and property security will be better protected.
The system is mainly pided into four parts, namely: pyroelectric detection sensor, CO sensor; AT89S51 processing module; residential warning lights, sirens module and the short message alarm notification module.
The system compact and reliable, strong expansibility, applicable to the residential indoor environment, warehouse etc.. And the price is low, low energy consumption, is in line with the current situation of our country a new thiefproof and fireproof alarm system.
Key Words：Automatic alarm system; sensor signal detection; SCM; short message alarm.
