基于单片机的矿井瓦斯浓度监测系统的研究

Monitoring System of Gas Concentration of Mine Based on Single Chip Microcomputer

为了实现对煤矿井下瓦斯气体浓度的准确、快速、实时监测和预警,介绍了一种由单片机控制的新型瓦斯浓度监测系统,针对瓦斯催化元件高温激活的难题,文中采用了恒温瓦斯检测技术,设计了闭环控制回路的思想保证了采样温度的恒定,避免了温度对瓦斯检测浓度的影响。该系统不仅可以实时分析、处理处理数据,同时还可以保存相关数据、启动报警及发送数据,通过红外控制系统实行远程监控的目的。可以应用到大型矿区及其他需监测易燃易爆的场合。

In order to realize the coal mine gas concentration＇s accurate,rapid,real-time monitoring and early warning,this paper introduced a single-chip control of the monitoring system of gas concentration,gas catalytic element for high temperature activation of the problem.The paper adopted the thermostatic methane detection technology,the design of the close-loop control thought assurance sampling temperature constant,avoid the effect of temperature on gas detection concentration.The system can be analyzed in real-time,processing data,and can save the data,activating the alarm and send data,through the infrared control system to implement the purpose of remote monitoring.It can be applied to large mining area and other monitoring inflammable and explosive occasions.
