近年来，瓦斯爆炸、煤与瓦斯突出等灾害，严重威胁着煤矿的安全生产和数百万名煤矿工人的生命安全，瓦斯灾害已成为制约我国煤矿安全生产和煤炭工业发展的重要因素，可以说瓦斯爆炸已经成为矿难的第一大祸首。因此瓦斯检测对于煤矿的安全生产和保护矿工的生命安全就有着非常重要的意义
本文以51系列单片机AT89S52作为核心控制部件，主要论述了便携式瓦斯报警仪的设计过程，并针对传统瓦斯催化剂元件法由于温度升高而使催化元件灵敏度降低，寿命缩短的问题进行了改进，设计了一种简单的恒温检测瓦斯浓度的方法。本设计的硬件电路包括单片机系统、A/D转换、时钟电路和充电电路等，软件电路包括时钟芯片的驱动，数码管显示和声光报警等。通过系统的设计，使报警仪对矿井中的低浓甲烷实现连续实时监测瓦斯，及时掌握瓦斯浓度的变化，超值报警，便携式瓦斯报警仪具有体积小、重量轻、测量准确，使用维护方便的特点，用于煤矿井下各工作场所测量空气中的瓦斯浓度，以减少矿山瓦斯事故的发生率。
In recent years, gas explosion, coal and gas outburst and other disasters, serious threat to the safety of coal production and the lives of hundreds of thousands of coal miners safe, gas disaster has restricted the production of coal mine safety and an important factor in the development of the coal industry can be said of gas mine explosions have become the first major culprit. Therefore, detection of gas production for the mine safety and protection of the lives of miners has very important significance to
51 MCU AT89S52 this paper as a core control unit, mainly discusses the design of portable gas alarm device process and catalyst components for the traditional method of gas due to temperature decrease due to the rising sensitivity of catalytic sensor, the problem of shortened life expectancy has improved, designed A simple method of temperature detection of gas concentration. The design of the hardware circuit includes single chip system, A / D converter, clock circuit and charging circuit, the software driver circuit includes a clock chip, digital display and sound and light alarm and so on. Through the system is designed so that the alarm device of the low concentration of methane in the mine to achieve continuous real-time monitoring of gas, make the changes in gas concentration, alarm value, a portable gas alarm device has a small size, light weight, accurate measurement, easy maintenance characteristics of the workplace for the measurement of coal mine gas concentration in the air to reduce the incidence of mine gas accident.希望能帮助到你

In recent years, the gas explosion, coal and gas outburst, such disasters a serious threat to the safety of coal production and millions of coal worker's life safety, restricting our gas disaster has become the safety production in coal mine and the development of the coal industry, can say the important factors of gas explosion has become the first major culprit ore difficult. So the gas detection for coal mine safety in production and protect the life safety of the miners have very important significance
This paper to 51 series microcontroller as the core control components, AT89S52 mainly discusses the design process of portable gas alarming device, and in the light of traditional gas catalyst components due to temperature rises, the method of catalytic element sensitivity to reduce, life improved shortened problem, design a kind of simple constant temperature detection method of gas concentration. This design hardware circuit including single-chip microcomputer system, A/D conversion, clocking circuit and charging circuit, software circuit including clock chip driver, digital pipe display the audible and visual alarm and etc. Through the design of the system, make the alarming device against mine the low thick methane gas, achieve continuous real-time monitoring in grasping the gas concentration changes, overflow alarm, portable gas alarming device has small volume, light weight, measurement accuracy, use convenient maintenance, for the characteristics of coal mine underground workplace in each measure air gas concentration, in order to reduce the incidence of mine gas accident.
