Protues軟件 對(duì)主要模塊進(jìn)行仿真。 家用防盜系統(tǒng)近幾年來(lái)在全球以及在中國(guó)的快速發(fā)展是信息技術(shù)發(fā)展尋找更廣闊的市場(chǎng)結(jié)合點(diǎn)的必然結(jié)果，是 IT 產(chǎn)業(yè)向傳統(tǒng)住宅產(chǎn)業(yè)以及人們生活滲透的必然結(jié)果。目前歐美已有一些國(guó)家正在大力研究無(wú)線 防盜探測(cè)報(bào)警系統(tǒng)，隨著時(shí)間的推移，這種產(chǎn)品在我國(guó)也會(huì)發(fā)展成為主流 [2]。 第 2 頁(yè) 共 61 頁(yè) 課題研究背景及意義 隨著社會(huì)的發(fā)展，人們的活動(dòng)、居住區(qū)域越來(lái)越大，安全問(wèn)題越顯重要。伴隨著科學(xué)技術(shù)的不斷進(jìn)步，值得提出的是，我國(guó)目前民居內(nèi)幾乎沒(méi)有防火設(shè)施及救火器材，火災(zāi)報(bào)警系統(tǒng)必將得到更快的發(fā)展。 家用防盜系統(tǒng)近幾年來(lái)在全球以及
