ABSTRACT
With the rapid development of China's economy, various industries on the sharp increase in the demand for coal. but each kind of mining accident's occurrence, causes the coal safety in production faced with the stern challenge. This piece of article aims at the gas to carry on the monitoring to design. In the article, I in view of the gas characteristic, design simultaneously monitor the height density the gas system, all-weather uninterrupted carries on the monitor to the mine shaft gas density. Simultaneously uses the acousto-optics alarm system, once gas exceeding the allowed figure, the system reminds the downhole operation worker to evacuate urgently immediately, avoids the personnel casualty. Also put to use infrared remote-control system carry through long-distence supur risory control. Design this intelligent sensor adopt close-cycle control insure sampling placidity. This system take at87C552 monolithic integrated circuit as a core, realizes to the gas examination, the warning and the control, safe reliable, durable, suits each kind of coal mine gas the monitoring, may reduce coal mining accident's occurrence greatly, reduces the private costs, raises the coal recovery ratio, makes the contribution for our country coal enterprise. KEYWARDS: gas, AT87C552, PID controller

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。
