随着现代建筑的不断增多，火灾隐患增加，一旦发生火灾，将对人的生命财产造成极大的危害。现代建筑具有智能化的时代特征，火灾自动报警系统(FAS)探测火灾隐患，肩负安全防范重任，在现代智能建筑中起着极其重要的安全保障作用。在工业和民用建筑、宾馆、图书馆、科研和商业部门，火灾自动报警系统已成为必需的装置。 火灾报警控制器(FAC)是一种能向火灾探测器供电、接收、传递和显示火灾报警等信号，并能对自动消防装置发出控制信号的报警装置。它是火灾自动报警系统的重要组成部分。本文主要对火灾报警控制器的理论做了深入的研究，并全面阐述了研制一个能实际应用的火灾报警控制器硬件部分和软件部分的方法和过程。 本论文一共分为四部分介绍。第一部分是绪论，介绍了国内外火灾自动报警系统发展的历史、现状、趋势以及火灾自动报警系统的分类，简要说明了研制火灾自动报警控制器的意义和硬件部分的研制过程；第二部分是火灾自动报警系统硬件组成及原理，分别介绍控制器C8051单片机的应用、传感器及其信号调理电路、声光报警控制电路、步进电机驱动控制电路、网络接口电路以及电源电路；第三部分是火灾自动报警系统软件，系统软件包括在单片机上运行的嵌入式程序以及在上位机上运行的通信串口程序两部分。前者通过Keil C51完成，整个程序由主程序、数据采集输入子程序、电机转动子程序、判断火灾子程序、串行通信子程序、自动灭火处理等若干子程序构成。后者选用的应用程序开发工具是VisualC++6.0实现单片机和PC机之间的串口通信从而实现三个功能：1 观察运行状态；2 可以通过上位机来改变系统的参数来改变系统的运行状态；3 实现人工模拟检测电机功能；第四部分是总结展望。
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. While modern buildings take on smart character, The fire alarm system (FAS) 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.The fire alarm controller (FAC) is an important part of FAS, functioning to supply the fire detector, to receive, transfer and display fire alarm signals, to send the fire control devices control signals automatically. 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 process in developing a applied FAC.This thesis includes four main parts .This first part narrates the process of developing FAC hardware in detail. Introducing the modular design methodology. The second part is the hardware construction of the FAS and it"s principle. Introducing the application of C8051,the sensor and it"s signal process circuit; the sound and light alarm circuit, the stepping motor drive circuit, the network interface circuit 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 communication. The former is accomplished by Keil C51. It is composed of main program .motor driving program, series program, fire judgment program and lots of program. The latter comes out the series communication between MCU and PC by Visual C++6.0.Accordingly implement three functions: observing running state, changing running state by changing parameters and manual simulate motor inspect; The forth part is summarize and expectation.
