摘要

隨著現(xiàn)代建筑的不斷增多，火災(zāi)隱患增加，一旦發(fā)生火災(zāi)，將對(duì)人的生命財(cái)產(chǎn)造成極大的危害。現(xiàn)代建筑具有智能化的時(shí)代特征，火災(zāi)自動(dòng)報(bào)警系統(tǒng)探測(cè)火災(zāi)隱患，肩負(fù)安全防范重任，在現(xiàn)代智能建筑中起著極其重要的安全保障作用。在工業(yè)和民用建筑、賓館、圖書館、科研和商業(yè)部門，火災(zāi)自動(dòng)報(bào)警系統(tǒng)己成為必需的裝置。
本文主要對(duì)火災(zāi)報(bào)警控制器的理論做了深入的研究，并全面闡述了研制一個(gè)能實(shí)際應(yīng)用的火災(zāi)報(bào)警控制器硬件部分和軟件部分的方法和過程。共分四部分介紹：第一部分是緒論，介紹了國(guó)內(nèi)外火災(zāi)自動(dòng)報(bào)警系統(tǒng)發(fā)展的歷史、現(xiàn)狀、趨勢(shì)以及火災(zāi)自動(dòng)報(bào)警系統(tǒng)的分類，簡(jiǎn)要說(shuō)明了研制火災(zāi)自動(dòng)報(bào)警控制器的意義和硬件部分的研制過程;第二部分是火災(zāi)自動(dòng)報(bào)警系統(tǒng)硬件組成及原理，分別介紹控制器C8051單片機(jī)的應(yīng)用、傳感器及其信號(hào)調(diào)理電路、聲光報(bào)警控制電路、網(wǎng)絡(luò)接口電路以及電源電路;第三部分是火災(zāi)自動(dòng)報(bào)警系統(tǒng)軟件，系統(tǒng)軟件包括在單片機(jī)上運(yùn)行的嵌入式程序以及在上位機(jī)上運(yùn)行的通信串口程序兩部分。第四部分是總結(jié)展望。

Abstract
In the recent years,increasing of modern buildings leads to frequency of fire.In case fire happened,it will make huge damage to human’s life and property.Whlie modern buildings take on smart character,The fire alarm system is in charge of detecting and alarming fire in time,safeguarding beings and belongings.FAS has been a necessary setting in industrial and civilian buildings,hotels,libraries,scientific researches and business departments.
It is an important consist Part of the FAS.This paper makes in-depth research in the theory of FAC and expatiates the hardware and software method and proeess in developing a applied FAC.This thesis ineludes four main parts.This first part narrates the process of developing FAC hardware in detail.Introdueing the modular design methodology.The second part is the hardware construction of the FAS and it’s  principle.Introdueing the applieation of C8051,the sensor and it’s signal proeess circuit:the sound and light alarm eircuit，the stcpping motor driver circuit,the network interface cireuit and power circuit:The third part is the software of the FAS.The system software includes the embed Program running on the MCU and the program of series port in communieation.The former is accomplished by Keil C51.It is composed of main program,motor driving program,series Program,fire judglnent program and lots of program.The latter comes out the serics communication between MCU and PC by VisualC++6.0.Accordingly implement three funetions:observing running state,changing running state by changing parameters and manual simulate motor inspect;The forth part is summarize and expectation.
