1、摘 要 摘 要 随着我国经济的快速发展，各行各业对煤炭的需求急剧增加，而各种矿难事故的发 生，使得煤炭安全生产面临严峻的挑战。这篇文章就是针对导致矿难频发的瓦斯浓度进 行监控而设计的。 在文章里，我针对瓦斯的特点，设计出同时监测高低浓度的瓦斯系统，全天候不间 断的对井下瓦斯浓度进行监测。同时采用声光报警系统，一旦瓦斯超标，系统立即提醒 正在井下作业的工人紧急撤离，避免人员伤亡，并且还运用红外遥控系统来进行远程监 控。设计这种智能传感器采用闭环控制来确保采样的平稳。 该传感器以 AT89S52 单片机为核心，实现对瓦斯的检测、报警和控制，安全可靠， 经久耐用，适合各类煤矿瓦斯的监控，可以大大降低
2、煤矿事故的发生，降低企业成本， 提高煤炭开采率，为我国煤炭事业做出贡献。 关键词：瓦斯；AT89S52；PID 控制器 Abstract Abstract With the rapid development of Chinas economy, various industries on the sharp increase in the demand for coal. but each kind of mining accidents occurrence, causes the coal safety in production faced with the stern challen
