1、床邊呼叫系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)院系:信息科學(xué)與工程學(xué)院專業(yè)班:電子科學(xué)與技術(shù)姓名:學(xué)號(hào):指導(dǎo)教師:2015年5月床邊呼叫系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)IDesignandImplementationofBedsideCallSystem摘要近年來(lái),隨著醫(yī)學(xué)用傳感器的小型化、信息處理和無(wú)線數(shù)據(jù)傳輸技術(shù)的快速發(fā)展和普及,使得無(wú)線醫(yī)療呼叫系統(tǒng)的研制成為熱點(diǎn)。各國(guó)科研機(jī)構(gòu)和跨國(guó)公司競(jìng)相開展無(wú)線醫(yī)療呼叫系統(tǒng)及其應(yīng)用研發(fā)。本課題研究的目的就是針對(duì)醫(yī)院病人呼叫的需求,設(shè)計(jì)一個(gè)基于單片機(jī)的床邊呼叫系統(tǒng)。該系統(tǒng)通過(guò)按鍵電路發(fā)出呼叫信號(hào)及警報(bào),由單片機(jī)的無(wú)線串口將數(shù)據(jù)傳輸至
2、另一個(gè)單片機(jī)的無(wú)線串口,經(jīng)單片機(jī)分析及處理后,再經(jīng)無(wú)線串口傳遞給顯示電路,后做出復(fù)位及關(guān)閉警報(bào)等應(yīng)答。本文文中結(jié)合呼叫系統(tǒng)主流特點(diǎn)情況,以床邊呼叫系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)為題,做了一個(gè)簡(jiǎn)單的基于STC89C52單片機(jī)床邊呼叫系統(tǒng),可以使病人更好、更簡(jiǎn)便、更快速的發(fā)送呼叫,護(hù)士也可以通過(guò)警報(bào)來(lái)查看顯示屏確認(rèn)呼叫病人的位置,可以快速的接收呼叫信號(hào),從而通知醫(yī)師來(lái)查驗(yàn),使病人能快速的得到醫(yī)師的救治,減少呼叫的人工時(shí)間。本系統(tǒng)設(shè)計(jì)小巧、輕便、簡(jiǎn)潔,可用于手持操作,方便攜帶。關(guān)鍵詞:呼叫系統(tǒng)單片機(jī)無(wú)線串口IVAbstractInrecentyears,
