科技学院新科学院2024 届本科毕业论文（设计）一氧化碳气体检测报警系统学生： 所在系别： 电气工程系所学专业： 电气工程与其自动化导师： 完成时间： 2024 年 5 月 10 日一氧化碳气体检测报警系统摘要本论文主要实现一氧化碳气体泄露的检测与报警，系统主要以半导体气体传感器为讨论对象，以单片机为核心构成一个具备信号产生、数据处理、模数转换、数据通信、报警电路等功能的完整系统。该系统的工作原理为：家庭用电经降压、稳压处理为整个电路供电，传感器将体积浓度转换成电压信号，经过线性放大、A/D 转换等一系列处理后，最后送入单片机 AT89S51 中与标准浓度对比进行检测。假如浓度超过限定值，报警器就会报警。这种电路具有有用性强、可靠性高、测量精度高等特点，可广泛应用于工业、医疗卫生、环境监测和日常生活等方面。关键词：一氧化碳气体，单片机，报警Detection of combustion gas leakage and warning systemAbstractIn this paper, the main gas leak measurement and alarm systems to the semiconductor gas sensor for the study in order to constitute a single-chip microcomputer as the core with data acquisition, object control, results showed that features such as data communication system of integrity. The system works as follows : DC Power Supply for the entire circuit, sensors will be converted into concentration voltage signals, after a series of linear processing, analogue switch to the A / D converters, Finally, figures show circuit testing ones and the gas concentration by single-chip microcomputer. If concentrations exceed the limit, the alarm will alarm. This circuit is practical, high reliability and high precision measurement can be widely used in industrial, medical and health, environmental monitoring and daily life, and so on.Key words ：carbon monoxide ,Single chip microcontroller ,alarm目录1 绪论 11.1 论文讨论的背景 11.2 论文讨论的目的 11.3 国外讨论现状与进展动态 11.4 系统设计的基本容 22 系统的总体设计 32.1 方案的选择 32.2 系统流程框...
