【正文】 I 基于單片機(jī)的瓦斯監(jiān)控系統(tǒng) 的硬件設(shè)計(jì) 電子信息工程專業(yè) ［摘 要］ 本文概述了瓦斯監(jiān)控器的現(xiàn)狀及其基本原理，主要論述了利用單片機(jī)實(shí)現(xiàn)瓦斯監(jiān)控器的設(shè)計(jì)與實(shí)現(xiàn)方法。瓦斯監(jiān)控器是一種采用單片機(jī)控制的智能化儀表，為了滿足煤礦井下使用攜帶方便、安全可靠等要求，在設(shè)計(jì)上作了如下的必要的考慮：考慮到小型化儀表的結(jié)構(gòu)，以及今后改進(jìn)的方便，我們將單片機(jī)進(jìn)行了模塊化處理。系統(tǒng)的各個(gè)模塊都由它控制完成。 本文針對目前情況設(shè)計(jì)一種井下便攜式瓦斯監(jiān)控器，當(dāng)瓦斯氣體濃度接近危險(xiǎn)值時(shí)，自動(dòng)發(fā)出報(bào)警，提醒井下人員立刻離開。該設(shè)備同時(shí)還具備靈 敏度調(diào)節(jié)和檢測強(qiáng)度調(diào)節(jié)開關(guān)，有簡單、方便、準(zhǔn)確、實(shí)用等特點(diǎn)。 ［關(guān)鍵詞］ 單片機(jī) ；瓦斯氣體檢測；氣敏傳感器；報(bào)警 Hardware Design of Gas Monitoring System Based on MCU Electrical amp。 Information Engineering Major Abstract: This paper has outlined the gas detector present situation and its the basic principle, mainly elaborated the use monolithic integrated circuit realization gas detector design and the realization method. The gas detector is one kind the intellectualized measuring appliance which uses the monolithic integrated circuit to control, in order to satisfy the coal mine mine shaft use to carry conveniently, safe is reliable and so on the request, has made the following necessity consideration in the design: Considered the miniaturized measuring appliance the structure, as well as next improvement convenient, we have carried on the monolithic integrated circuit modular processing. System each module all controls by it pletes. This paper designs one kind of mineshaft portable gas detector in view of the present situation, when the gas gas density approaches the dangerous value, automatically sends out reports to the police, the reminder mineshaft personnel leaves immediately. At the same time this equipment also has the sensitivity adjustment and the examination intensity regulating cock, has simply, convenient, accurate, is practical and so on the characteristic. Key words: AT89C51。 Gas gas detection。 Angry quick sensor。 Reports to the police 目 錄 1 引言 ............................................................................ 1 課題研究的目的和意義 ....................................................... 1 國內(nèi)外氣體檢測系統(tǒng)研究現(xiàn)狀 ................................................. 1 課題研究的內(nèi)容和方案 ....................................................... 2 II 課題研究的內(nèi)容及要求 ................................................. 2 課題研究的總體解決方案 ............................................... 2 2 瓦斯報(bào)警器的設(shè)計(jì)概述 ............................................................ 2 概述 ...................................................................... 2 設(shè)計(jì)方案 .................................................................. 2 系統(tǒng)分析 .................................................................. 4 本章小結(jié) .................................................................. 4 3 硬件系統(tǒng)設(shè)計(jì) .................................................................... 4 主控單元 .................................................................. 5 氣體采樣單元 .............................................................. 6 單片機(jī)控制單元 ............................................................ 7 按鍵電路 ............................................................ 7 調(diào)節(jié)執(zhí)行單元 ............................................................. 9 電源 ..................................................................... 10 報(bào)警單元 ................................................................. 10 4 仿真結(jié)果 ....................................................................... 12 5 總結(jié) ............................................................ 錯(cuò)誤 !未定義書簽。 設(shè)計(jì)實(shí)現(xiàn)情況與改進(jìn)方案 .................................................... 13 .................................................................. 14 結(jié)束語 ........................................................................... 13 參考文獻(xiàn) ......................................................................... 14 附錄 A 系統(tǒng)的原理圖 .............................................................. 15 致 謝 ............................................................................ 16 1 1 引言 課題研究
