壓(ya)(ya)(ya)風(feng)供(gong)(gong)氧(yang)(yang)：壓(ya)(ya)(ya)風(feng)供(gong)(gong)氧(yang)(yang)主(zhu)要是(shi)利用(yong)煤(mei)礦(kuang)中(zhong)的壓(ya)(ya)(ya)風(feng)系(xi)統向(xiang)硐室(shi)供(gong)(gong)應新鮮空氣，因(yin)為空氣中(zhong)含(han)有氧(yang)(yang)氣，因(yin)此相當于給硐室(shi)供(gong)(gong)應了充足的氧(yang)(yang)氣。但(dan)如果壓(ya)(ya)(ya)風(feng)管道在(zai)礦(kuang)難中(zhong)遭到破壞，則壓(ya)(ya)(ya)風(feng)供(gong)(gong)氧(yang)(yang)功能(neng)將停(ting)止，必須另想其它辦法(fa)予以(yi)供(gong)(gong)氧(yang)(yang)。(2)壓(ya)(ya)(ya)縮(suo)氣瓶供(gong)(gong)氧(yang)(yang)：壓(ya)(ya)(ya)縮(suo)氣瓶供(gong)(gong)氧(yang)(yang)是(shi)目前(qian)救生艙及硐室(shi)普(pu)遍采用(yong)的一(yi)種(zhong)安(an)全供(gong)(gong)氧(yang)(yang)方式。
(1)壓(ya)風(feng)供(gong)(gong)(gong)氧(yang)：壓(ya)風(feng)供(gong)(gong)(gong)氧(yang)主要是(shi)利用(yong)煤礦中的(de)壓(ya)風(feng)系統向硐室供(gong)(gong)(gong)應(ying)新(xin)鮮空(kong)氣(qi)，因為空(kong)氣(qi)中含有氧(yang)氣(qi)，因此相(xiang)當(dang)于給硐室供(gong)(gong)(gong)應(ying)了充足(zu)的(de)氧(yang)氣(qi)。但如果壓(ya)風(feng)管道在礦難中遭到破壞，則壓(ya)風(feng)供(gong)(gong)(gong)氧(yang)功能將停止，必須另想其它辦法(fa)予以(yi)供(gong)(gong)(gong)氧(yang)。(2)壓(ya)縮氣(qi)瓶供氧(yang)(yang)(yang)(yang)(yang)(yang)：壓(ya)縮氣(qi)瓶供氧(yang)(yang)(yang)(yang)(yang)(yang)是(shi)(shi)目前(qian)救生艙及(ji)硐室普遍(bian)采用的(de)(de)一種安全供氧(yang)(yang)(yang)(yang)(yang)(yang)方式。它是(shi)(shi)一種不依賴外界支持就能獨立工作(zuo)的(de)(de)供氧(yang)(yang)(yang)(yang)(yang)(yang)方式，在壓(ya)風未被破壞的(de)(de)情況下優先(xian)采周壓(ya)風供氧(yang)(yang)(yang)(yang)(yang)(yang)，在壓(ya)風遭(zao)受破壞的(de)(de)情況下，必須啟(qi)用壓(ya)縮氣(qi)瓶方式進(jin)行供氧(yang)(yang)(yang)(yang)(yang)(yang)。氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)供應自(zi)控系統(tong)包括氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)供應自(zi)控箱、氣(qi)瓶減壓(ya)器、氧(yang)(yang)(yang)(yang)(yang)(yang)氣(qi)傳感器、金屬(shu)壓(ya)力軟管(guan)、通(tong)訊線(xian)纜以及(ji)匯流排(pai)組(zu)成。
1)對壓(ya)縮氧氣(qi)瓶實現匯流并集中供氣(qi)。氧氣(qi)瓶數不限，皆通過本(ben)系(xi)統自(zi)動控制(zhi)。2)自動(dong)偵測艙內氧氣(qi)濃度（采用任(ren)意氧氣(qi)濃度傳感器）．當氧氣(qi)濃度低于某設定值時(shi)（如18.5%）．系統自動打開電磁閥進(jin)行充氧；當氧氣濃度高于某一設定(ding)值時(如23%)，系統自動關閉電磁(ci)閥停(ting)止充氧(yang)。3)可(ke)(ke)以(yi)實現聲光(guang)(guang)(guang)報(bao)(bao)(bao)警(jing)(jing)，即用戶(hu)可(ke)(ke)以(yi)設定一個報(bao)(bao)(bao)警(jing)(jing)濃(nong)度(du)，當氧氣濃(nong)度(du)低于(yu)該(gai)值時，控(kong)制板自動進行聲音(yin)報(bao)(bao)(bao)警(jing)(jing)或屏(ping)幕燈光(guang)(guang)(guang)閃(shan)爍(shuo)報(bao)(bao)(bao)警(jing)(jing)（當偏離度(du)越大(da)，報(bao)(bao)(bao)警(jing)(jing)聲音(yin)越急促，燈光(guang)(guang)(guang)閃(shan)爍(shuo)越快速）。用戶(hu)可(ke)(ke)以(yi)關閉聲音(yin)報(bao)(bao)(bao)警(jing)(jing)和燈光(guang)(guang)(guang)閃(shan)爍(shuo)報(bao)(bao)(bao)警(jing)(jing)功能。4)氧氣濃度上限(xian)值、下限(xian)值、報警值可以通過觸摸屏(ping)靈活設定(ding)。5)通過4寸(cun)彩色液晶屏(ping)動(dong)態顯示低濃(nong)度(du)區(qu)(qu)(qu)、適宜濃(nong)度(du)區(qu)(qu)(qu)及高濃(nong)度(du)區(qu)(qu)(qu)，顯示直觀清(qing)晰(xi)，方便用戶觀察。6)系統自適應氧氣(qi)濃度傳感(gan)器的開機預熱行為(wei)，即(ji)部(bu)分(fen)氧氣(qi)濃度傳感(gan)器加電后(hou)會有10- 20秒的穩定過程，此時系統自動判斷氧氣濃度傳感器(qi)的穩定狀態，然后再(zai)做出相應的控制(zhi)動作(zuo)。7)氣(qi)體管(guan)路末端(duan)帶(dai)流量控(kong)制計音阻(zu)尼裝置，使(shi)氧氣(qi)緩慢勻(yun)稱(cheng)釋放。8)氣體管(guan)路采用雙路控制，即自(zi)動(dong)裝置失(shi)效后，用戶可以馬上切換(huan)使(shi)用手動(dong)調節(jie)。9)該系統以節約穩定的方(fang)式供氧，避免造成氧氣過度浪費(fei)。
