【正文】 ,而且影響了社會(huì)政治穩(wěn)定。當(dāng)火災(zāi)發(fā)生時(shí),正常供電可能無(wú)法使用,這時(shí)候智能應(yīng)急燈就為撤離人員和消防人員提供了應(yīng)急照明。 隨著科技的進(jìn)步和社會(huì)的發(fā)展,單體建筑的面積越來(lái)越大,建筑高度越來(lái)越高,聚集的人員越來(lái)越多,當(dāng)建筑物內(nèi)部發(fā)生火災(zāi)時(shí),造成人員嚴(yán)重傷亡的危險(xiǎn)性越來(lái)越大,所以良好的應(yīng)急照明系統(tǒng)是一個(gè)相 當(dāng)重要的安全設(shè)施,是保障建筑物內(nèi)人員安全、及時(shí)疏散的前提,并且利于救援工作的順利進(jìn)行,從而最大限度地減少人員的傷亡和降低財(cái)產(chǎn)的損失。 主控制器和應(yīng)急燈單元共同構(gòu)成多單片機(jī)通信系統(tǒng),應(yīng)急燈嵌入的單片機(jī)主要完成應(yīng)急燈狀態(tài)采集、點(diǎn)亮或熄滅應(yīng)急燈的功能,并與主控制器進(jìn)行通信。本課題設(shè)計(jì)的智能應(yīng)急燈系統(tǒng)主控制用 MCS51 單片機(jī)作微處理器,應(yīng)急燈單元也用MCS51 系列單片機(jī)作 微處理器。對(duì)傳統(tǒng)應(yīng)急燈控制電路的改進(jìn)。 隨著電子技術(shù)和微型計(jì)算機(jī)的迅速發(fā)展,促進(jìn)了微型計(jì)算機(jī)測(cè)量和控制技術(shù)的迅速發(fā)展和廣泛應(yīng)用,單片機(jī)的應(yīng)用已經(jīng)滲透到國(guó)民經(jīng)濟(jì)的各個(gè)部門(mén)和領(lǐng)域,它起到了越來(lái)越重要的作用。 關(guān)鍵詞: 單片機(jī)、應(yīng)急燈、消防、 RS485 通信 無(wú)錫科技職業(yè)學(xué)院畢業(yè)設(shè)計(jì)(論文) 智能應(yīng)急燈系統(tǒng)的設(shè)計(jì) ii A Design of MCUbased Controller of Emergency Luminary Abstract: This paper presents an emergency luminary controller based on singlechip microputer. The design uses the MCS51 microcontroller as the core and meets the requirement of the national standards for fire emergency luminary GBl79452020. Firstly, the technical background, the current study and the development trend of the fire emergency evacuation lighting as well as the significance and the objectives of this design are expound. Then, the classification of the fire emergency luminary widely used and the principle of selfpowered emergency luminary for fire fighting are highlighted. The overall structure diagram according to the national standard is also presented. Subsequently, after the key devices were reasonably chosen, the specific circuit diagram of three important modules including the power modules, the CPU module and the photoelectrical isolated munication module are presented. The operation of every module is analyzed. The functions of powerdown detection, power conversion, battery state detection, lighting LED state inspection and RS485 munication are achieved. In the design of software, the work logic of the controller and the main block diagram of the system are introduced. The flowchart to analyze the three states of battery, open circuit, short circuit and the normal are drawn.
