③ 摘要
這篇論文描述了一種基于變頻和脈動通風(fēng)技術(shù)來實現(xiàn)煤礦推進(jìn)面智能通風(fēng)的控制系統(tǒng)。系統(tǒng)分析瓦斯受感器傳來的瓦斯密度信號并分析此密度對煤礦推進(jìn)面的影響。實際中我們通過控制通風(fēng)機(jī)的旋轉(zhuǎn)速度來實現(xiàn)煤礦推進(jìn)面的智能通風(fēng)。當(dāng)瓦斯密度突然增加，系統(tǒng)會發(fā)出警報，這時通風(fēng)機(jī)的旋轉(zhuǎn)速度加快，這樣一來瓦斯就很快被排放出去，這就保證的煤礦推進(jìn)面的生產(chǎn)安全

This paper presents a ventilation intelligent control system of mining driving face based on frequencies change technique and pulsating ventilation technique．This system call analyse the gas concentration signal from the gas sensor and make a judgement to the environment of mining driving face．Control the rotate speed of the auxiliary fan in real—time．In order to realize the ventilation intelligent control of mining driving face．When the gas gushes instantly．The system gives out a sound—light alarm and the rotate speed of the auxiliary fan will be accelerated，so the gas concentration will be diluted immediately．The production safety of the mining driving face can be insured．
