煤(mei)炭開采過程中，出于(yu)對(dui)安全生(sheng)產的(de)需(xu)要(yao)(yao)，會應用各種(zhong)各樣的(de)監測、監管、控(kong)(kong)制(zhi)等(deng)信息系統(tong)，對(dui)煤(mei)礦(kuang)各個方(fang)面(mian)進行監測管理，以避(bi)免或減(jian)少(shao)煤(mei)礦(kuang)安全事(shi)故發生(sheng)。在(zai)煤(mei)礦(kuang)行業，采用自(zi)動化作(zuo)業，就(jiu)要(yao)(yao)利用控(kong)(kong)制(zhi)設備(bei)實現對(dui)設備(bei)的(de)智(zhi)能控(kong)(kong)制(zhi)。隨著越來(lai)越多的(de)信息設備(bei)和系統(tong)應用于(yu)煤(mei)礦(kuang)企業，針對(dui)這些(xie)設備(bei)的(de)管理也(ye)變得復雜，利用人工也(ye)無法滿足現代化煤(mei)礦(kuang)企業的(de)需(xu)求。綜合各種(zhong)情況(kuang)，煤(mei)礦(kuang)自(zi)動化離(li)不開智(zhi)能、信息、自(zi)動控(kong)(kong)制(zhi)設備(bei)。

針對煤礦各種系統和設備的控制保護，離不開各種控制設備，如礦用可編程控制箱、礦用防爆計算機、礦用防爆操作臺等。其中，礦用可編程控制箱在其中起(qi)到至關重要的作用(yong)，是煤(mei)礦(kuang)自動化系統的核(he)心控(kong)制裝置。

礦用可(ke)編(bian)程(cheng)控(kong)制(zhi)(zhi)(zhi)箱(xiang)內置PLC作(zuo)為可(ke)編(bian)程(cheng)控(kong)制(zhi)(zhi)(zhi)器(qi)，具有模擬量采(cai)集(ji)、數據(ju)(ju)處理、通(tong)訊(xun)等(deng)功(gong)能(neng)(neng)，可(ke)以(yi)采(cai)集(ji)現(xian)場受控(kong)設(she)備的運行數據(ju)(ju)和傳(chuan)(chuan)感(gan)器(qi)信號數據(ju)(ju)，通(tong)過(guo)(guo)PLC的程(cheng)序(xu)控(kong)制(zhi)(zhi)(zhi)，實(shi)現(xian)對各(ge)(ge)種(zhong)井(jing)下電氣傳(chuan)(chuan)動系(xi)統(tong)(tong)的智(zhi)能(neng)(neng)化集(ji)控(kong)；通(tong)過(guo)(guo)顯示(shi)屏的組態(tai)畫面(mian)，能(neng)(neng)夠直觀(guan)、方便(bian)、清晰地(di)(di)顯示(shi)控(kong)制(zhi)(zhi)(zhi)系(xi)統(tong)(tong)各(ge)(ge)個節(jie)點的實(shi)時工作(zuo)狀態(tai)、監控(kong)數據(ju)(ju)等(deng)；可(ke)編(bian)程(cheng)控(kong)制(zhi)(zhi)(zhi)箱(xiang)具有聯網(wang)通(tong)訊(xun)功(gong)能(neng)(neng)，可(ke)以(yi)降控(kong)制(zhi)(zhi)(zhi)系(xi)統(tong)(tong)的各(ge)(ge)種(zhong)運行狀態(tai)遠程(cheng)傳(chuan)(chuan)輸到(dao)調度室等(deng)地(di)(di)面(mian)上(shang)位機進(jin)行監控(kong)。礦用可(ke)編(bian)程(cheng)控(kong)制(zhi)(zhi)(zhi)箱(xiang)應用于(yu)煤(mei)礦各(ge)(ge)種(zhong)自動化、信息化系(xi)統(tong)(tong)之(zhi)中，根據(ju)(ju)設(she)備的運行實(shi)況和傳(chuan)(chuan)感(gan)器(qi)采(cai)集(ji)到(dao)的信息，實(shi)現(xian)對系(xi)統(tong)(tong)中設(she)備的邏輯(ji)自動控(kong)制(zhi)(zhi)(zhi)。

具體舉例來說，礦(kuang)(kuang)用(yong)可(ke)編程(cheng)(cheng)控制(zhi)(zhi)箱可(ke)以應(ying)用(yong)于(yu)煤(mei)礦(kuang)(kuang)井下(xia)排(pai)(pai)水(shui)監(jian)控系統、膠帶輸送機控制(zhi)(zhi)保護系統、井下(xia)道(dao)路交通管(guan)理(li)控制(zhi)(zhi)等。礦(kuang)(kuang)用(yong)可(ke)編程(cheng)(cheng)控制(zhi)(zhi)箱應(ying)用(yong)于(yu)煤(mei)礦(kuang)(kuang)井下(xia)水(shui)泵(beng)房(fang)排(pai)(pai)水(shui)系統之中(zhong)，將可(ke)編程(cheng)(cheng)控制(zhi)(zhi)箱與被(bei)控設備連接(jie)，實(shi)時地監(jian)測(ce)水(shui)泵(beng)等設備運行(xing)狀態，并且可(ke)以根據監(jian)測(ce)結果(guo)進(jin)行(xing)自動啟停等控制(zhi)(zhi)操(cao)作，實(shi)現煤(mei)礦(kuang)(kuang)井下(xia)排(pai)(pai)水(shui)系統自動運行(xing)，提高其安全性、可(ke)靠性和高效運行(xing)，實(shi)現井下(xia)水(shui)泵(beng)房(fang)無人(ren)值守。

礦用可(ke)編程(cheng)控(kong)制(zhi)箱應用于(yu)膠帶(dai)輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)控(kong)制(zhi)保(bao)護系統之(zhi)中，通(tong)過連接輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)控(kong)制(zhi)裝(zhuang)(zhuang)置(zhi)等，根據輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)監測數據進行(xing)輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)的啟(qi)停(ting)，實(shi)現對輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)的控(kong)制(zhi)保(bao)護。例如，當(dang)輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)堆煤、偏載或(huo)撕裂(lie)時(shi)，啟(qi)動(dong)緊急裝(zhuang)(zhuang)置(zhi)停(ting)止輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)繼續運行(xing)，防止發(fa)生(sheng)安全事故；當(dang)發(fa)生(sheng)煙霧時(shi)，啟(qi)動(dong)煙霧報警器和灑水裝(zhuang)(zhuang)置(zhi)等。通(tong)過輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)運行(xing)時(shi)間(jian)等判(pan)斷(duan)，可(ke)以避免無效輸(shu)(shu)(shu)送(song)(song)(song)(song)機(ji)(ji)(ji)的無效運行(xing)，提高(gao)運行(xing)效率、節約能耗。

可以說，沒(mei)有(you)礦(kuang)(kuang)用(yong)(yong)(yong)(yong)可編(bian)程(cheng)控制(zhi)(zhi)(zhi)(zhi)箱，煤礦(kuang)(kuang)井下(xia)一系(xi)列各種系(xi)統根本(ben)無(wu)法真正(zheng)實現自動化、無(wu)人(ren)值守。而(er)且，礦(kuang)(kuang)用(yong)(yong)(yong)(yong)可編(bian)程(cheng)控制(zhi)(zhi)(zhi)(zhi)箱在實際應(ying)用(yong)(yong)(yong)(yong)過程(cheng)中(zhong)體現了其獨特的(de)(de)、不可替代(dai)的(de)(de)優勢：（1）可靠性(xing)高，具(ju)備(bei)高可靠性(xing)、強(qiang)抗干擾性(xing)、環(huan)境適應(ying)能力(li)(li)強(qiang)等特點(dian)；（2）配置靈(ling)活，PLC具(ju)有(you)極大靈(ling)活性(xing)和極強(qiang)的(de)(de)處理能力(li)(li)，當現場控制(zhi)(zhi)(zhi)(zhi)要(yao)求發生變化時，只需(xu)要(yao)按需(xu)改變程(cheng)序，靈(ling)活方便地(di)進行系(xi)統配置；（3）擴展性(xing)強(qiang)，礦(kuang)(kuang)用(yong)(yong)(yong)(yong)可編(bian)程(cheng)控制(zhi)(zhi)(zhi)(zhi)箱具(ju)有(you)很(hen)強(qiang)的(de)(de)組(zu)網(wang)和擴展能力(li)(li)，若(ruo)后續使用(yong)(yong)(yong)(yong)需(xu)要(yao)增(zeng)加(jia)設備(bei)和控制(zhi)(zhi)(zhi)(zhi)，可以靈(ling)活擴展。

總之，礦用可編程控(kong)制(zhi)(zhi)箱是煤礦自(zi)(zi)動(dong)化(hua)系統實現自(zi)(zi)動(dong)、智能控(kong)制(zhi)(zhi)的裝置(zhi)，沒有它，煤礦就無法真正實現自(zi)(zi)動(dong)化(hua)，而且礦用可編程控(kong)制(zhi)(zhi)箱在(zai)自(zi)(zi)動(dong)化(hua)應用中也(ye)提現了獨特(te)優勢。
