成都理工大学工程技术学院毕业论文 PAGE 家庭火灾报警系统的设计 作者姓名：2B 专业名称：测控技术与仪器 指导教师：2B 基于单片机的家庭火灾报警系统 - PAGE 18 - 摘要 目前，随着电子产品在人类生活中的使用越来越广泛，由此引起的火灾也越来越多，在我们生活得四周到处潜伏着火灾隐患。为了避免火灾以及减少火灾造成的损失，我们必须按照“隐患险于明火，防患胜于救灾，责任重于泰山”的概念设计和完善火灾自动报警系统，将火灾消灭在萌芽状态，最大限度地减少社会财富的损失。 本文采用气体传感器、温度传感器、AT89S52单片机以及LED显示灯模块设计了一种智能火灾报警器，可以实现声光报警、故障自诊断、浓度显示、报警限设置、延时报警及等功能。文中详细介绍了主控核心芯片、外围芯片的工作原理，各模块电路的硬件设计；叙述了软件工作流程和各子程序的工作流程。 关键词:单片机 火灾报警 传感器 硬件设计 软件设计 Abstract Now, along with the electronic products in the use of human life is more and more extensive, the cause of the fire more and more, in our life everywhere around potential fire hazard. In order to avoid fire and reduce the loss caused by fire, we must, in accordance with the hidden trouble risks in bright fire, the committee is better than relief, responsibility than mount tai concept design and perfect automatic fire alarm system, will fire nipped in the bud, minimize the loss of wealth of society. In this article, the gas sensor, the temperature sensor, and AT89S52 SCM LED display light module design a kind of intelligent fire alarm, can achieve sound and light alarm, fault diagnosis, concentration, the alarm limit that setting, delay alarm and etc. Function. This paper introduces the main control core chip, peripheral chip principle of work, each module circuit hardware design; Describes the software work flow and the procedure flow of work. Key?words: A single-chip microcomputer fire alarm sensor hardware design software design  目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc324930387 摘要 PAGEREF _Toc324930387 \h I HYPERLINK \l _Toc324930388 Abstract PAGEREF _Toc324930388 \h II HYPERLINK \l _Toc324930389 目录 PAGEREF _Toc324930389 \h III HYPERLINK \l _Toc324930390 第1章 前 言 PAGEREF _Toc324930390 \h 1 HYPERLINK \l _Toc324930391 1.1 选题背景及意义 PAGEREF _Toc324930391 \h 1 HYPERLINK \l _Toc324930392 1.2 火灾报警系统的类型 PAGEREF _Toc324930392 \h 1 HYPERLINK \l _Toc324930393 1.3 火灾探测的原理 PAGEREF _Toc324930393 \h 2 HYPERLINK \l _Toc324930394 1.4 论文的主要内容
