【正文】 基于單片機(jī)的火災(zāi)防盜報(bào)警系統(tǒng)的設(shè)計(jì) 摘 要 隨著社會(huì)的發(fā)展，單個(gè)家庭的經(jīng)濟(jì)積累越來(lái)越多，人們對(duì)于家庭災(zāi)情的防控也給予了越來(lái)越多的重視。目前，家庭災(zāi)情主要體現(xiàn)在火災(zāi)和盜竊兩個(gè)方面，因此，對(duì)于這兩種狀況的預(yù)防和監(jiān)控成為了家庭防災(zāi)的重點(diǎn)。本文就是基于這一社會(huì)現(xiàn)象設(shè)計(jì)了一種簡(jiǎn)單的防火防盜系統(tǒng)。 本文分兩部分來(lái)設(shè)計(jì)，一部分為基于 AT89S52單片機(jī)的火災(zāi)監(jiān)控系統(tǒng)，能夠及時(shí)監(jiān)測(cè)到系統(tǒng)故障和環(huán)境中有無(wú)火災(zāi)，火災(zāi)一旦發(fā)生將實(shí)現(xiàn)聲光報(bào)警，并采取有效措施控制火情的發(fā)展，將火災(zāi)消滅在萌芽狀態(tài)，以確保人身財(cái)產(chǎn)安全并最大限度地減少 損失。另一部分為基于 AT89C51單片機(jī)的，集傳感器檢測(cè)技術(shù)、智能控制和無(wú)線電技術(shù) 于 一體的防盜報(bào)警系統(tǒng)。本文對(duì)這兩部分分別行進(jìn)硬件電路搭建，軟件程序設(shè)計(jì)，最后對(duì)軟件進(jìn)行測(cè)試，運(yùn)用 Protues軟件 對(duì)主要模塊進(jìn)行仿真。 關(guān)鍵詞 ： 單片機(jī)，傳感器，火災(zāi)，門控， Protues Design Of Fire Alarm System Based On SCM Abstract With the social development, singlefamily economic has been accumulating,and more and more people pays attention to the family disaster prevention and control .Currently, the family disaster mainly reflected in two aspects of fire and , the prevention and control for these two conditions has bee the focus of family article has designed a simple fire alarm systems based on this social phenomenon. This article is designed in two parts,.One is fire monitoring system based on the AT89S52 was able to monitor the failures of system and the environment fires, it would achieve the sound and light alarm, and take effective measures to control the development of the fire, the fire will be nipped in the bud ,to ensure personal and property safety and minimize other is the antitheft alarm system based on the AT89C51 SCM,which bines sensor technology, intelligent control and radio technology and paper make the hardware circuit structures and design the software programming respectively. Finally, made a test for the software and simulated the main module by Protues.
