基于单片机的煤气浓度检测及报警系统设计

基于单片机的煤气浓度检测及报警系统设计摘要目前中国经济快速发展，人们的生活水平得到了很大提高，煤气也普遍进入了人们的日常生活中，但是在我们的日常生活中发生煤气泄漏的事件频频发生，给人们的生活和财产安全造成重大隐患。本次设计的主要内容是针对煤气检测方面做出一些研究，同时通过煤气(C0)传感器检测出煤气浓度。在主控制器模块的控制下。煤气传感器输出0至5伏电压。通过模拟到数字转换模块。将0至5伏电压转移到数字信号的单片机上。通过单片机处理接收信号，检测信号是否和设定值相同。本文以煤气检测仪为例，介绍了煤气传感器显示、数字模式转换、单片机等的应用，并通过软件仿真的方法，对电路和软件子程序进行了分析，并对子程序流程图进行了分析。关键词：单片机：显示：煤气浓度测量AbstractAt present,China's rapid economic development,people's living standards have beengreatly improved,gas has also generally entered people's daily life,but in our daily life gasleakage incidents occur frequently,causing major hidden dangers to people's lives and propertysafety.The main content of this design is to do some research on gas detection,and at the sametime detect the gas concentration through gas (CO)sensors.Under the control of the hostcontroller module.The gas sensor outputs a voltage of 0 to 5 volts.Conversion modules viaanalog-to-digital.Transfer a voltage of 0 to 5 volts to a microcontroller with a digital signal.Thereceived signal is processed by the microcomputer to detect whether the signal is the same as theset value.Taking the gas detector as an example,this paper introduces the application of gas sensordisplay,digital mode conversion,single-chip microcomputer,etc.,and analyzes the circuit andsoftware subroutine through software simulation,and analyzes the subprogram flow chart.Key Words:MCU;Display;Gas concentration measurement目录摘要Abstract..第一章绪论1.1课题研究的背景及意义1.2国内外研究现状.1.3论文结构安排….2第二章系统总体设计方案….32.1系统设计任务及要求..32.2系统的设计方案..3第三章系统硬件电路设计.53.1单片机….53.2复位电路设计..63.3煤气检测电路设计」..63.4显示电路设计….73.5按键电路设计….83.6AWD电路设计.93.7蜂鸣器电路设计.9第四章系统软件设计.….114.1主程序的设计.114.2各子程序的设计124.2.1数据采集模块124.2.2显示模块134.2.3报警模块.14第五章系统仿真.,5.1仿真软件….16
