我国是煤炭生产大国,随着煤矿机械化程度的不断提高,矿井生产能力和生产效率普遍加大,我国煤炭年产量居世界首位,产煤量占世界总产煤量的20%.但同时我国也是煤矿安全形势最为严峻的国家之一.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.

答案

Our country is coal production country, with coal mechanization degree unceasing enhancement, the mine production capacity and efficiency of production increase, our coal output generally first in the world, the amount of coal production quantity of coal output of the world by 20%. But at the same time China coal mine safety situation is one of the countries with the most severe. 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.
