隨著超大規(guī)模集成電路、通信技術(shù)、單片機(jī)技術(shù)的迅猛發(fā)展和人們保護(hù)意識的日漸增強(qiáng)，利用單片機(jī)及其它外圍芯片實(shí)現(xiàn)自動報(bào)警已成為可能，且是一種發(fā)展趨勢。另一方面社會上廣大的開發(fā)商、工程業(yè)主等也逐漸加大了智能建筑的投資。復(fù)合式探測器一般有超聲波 /被動紅外復(fù)合式探測器、微波 /被動紅外復(fù)合式探測器。目前市場上有不少此類產(chǎn)品，例如美國 Camp。因此，本文將提出一種整體設(shè)計(jì)方案，以求解決原有家用報(bào)警 器的不足，完善其功能，提高其可靠性。硬件就好比系統(tǒng)的骨架，只有硬件具有了高可靠性，才能支撐起軟件良好實(shí)現(xiàn)系統(tǒng)所要達(dá)到的功能。在設(shè)計(jì)家用無線防盜報(bào)警器的硬件、軟件系統(tǒng)時，針對很多同類產(chǎn)品的不足，相應(yīng)地增加了家用無線防盜報(bào)警器的功能。 模塊 化設(shè)計(jì) 根據(jù)本系統(tǒng)是用于防盜報(bào)警的這一特殊應(yīng)用目
