“Sidinga izinhlelo ukuthi zibe lula ukuzisebenzisa, futhi ziguquguquke, njengoba ukuzenzakalela okujwayelekile akusho izikhungo ezijwayelekile.” U-Alan Bryant we-Occidental uxoxe ngesifiso senkampani sokwenza amapulatifomu ayo okuzenzakalela e-Permian Basin abe sezingeni elifanayo kumakhabethe ambalwa e-Rockwell Automation ahlanganiswe efektri.
“Sidinga izinhlelo ukuthi zibe lula ukuzisebenzisa, futhi ziguquguquke, njengoba ukuzenzakalela okujwayelekile akusho izikhungo ezijwayelekile.” U-Alan Bryant we-Occidental uxoxe ngesifiso senkampani sokwenza amapulatifomu ayo okuzenzakalela e-Permian Basin abe sezingeni elifanayo kumakhabethe ambalwa e-Rockwell Automation ahlanganiswe efektri.
Inani elikhulayo njalo lemishini yakudala enezilawuli ezingafani nezigugile kungenzeka kungabi yindawo efanele yokuqala ukulinganisa, kodwa ngokuqinisekile kukwenza uyifune. Ngo-2000, imisebenzi ye-Occidental Petroleum's Permian Basin yanda ngokuthengwa kwemithombo ekhona evela eShell, e-Amoco nakwamanye, kufaka phakathi izinhlelo zabo ezikhona.
“Cishe besinayo yonke into eyake yenziwa, kanye nezinhlelo eziningi ezahlukene ze-SCADA,” kusho u-Alan Bryant, umeluleki omkhulu wobunjiniyela bokuzenzakalela, e-Occidental, owethule nozakwabo uMauricio Castillo, umeluleki wezinhlelo zokulawula izimboni, eNgqungqutheleni ka-Oyili neGesi e-Automation Fair 2019 kuleli sonto eChicago.
I-Occidental isebhizinisini elikhuphukayo. “Siyipompa emhlabathini, sihlukanise uwoyela, amanzi kanye negesi, bese siyithengisa,” kusho uBryant. Isifunda sayo sasePermian singamakhilomitha-skwele angu-75,000 ngaphezu kwentshonalanga yeTexas neNew Mexico. “Insimu esikhuluma ngayo ingamakhilomitha-skwele angu-90, indawo ebanzi yokumboza nge-SCADA, enezinkulungwane zemithombo,” kusho yena.
UBryant wajoyina inkampani ngo-2003, kanti umsebenzi wakhe wokuqala kwakuwukuthuthukisa uhlelo lwe-SCADA oluzenzakalelayo oluvulekile ukuze luhlanganise lawo mithombo ndawonye. Ngo-2005, iqembu lakhe lalinganisa ohlwini lwabathengisi oluvunyiwe, “kodwa ukuba nehadiwe yesikhathi esidlule kwakusho nokuthi sinabaningi abagugile, futhi sasingakwazi ukuyifinyelela kubathengisi be-PLC abathathu kuphela,” esho. Noma kunjalo, balinganisa ihadiwe, amaphrothokholi kanye nokuhlela emazingeni aphezulu.
“Ngo-2011, sanquma ukusebenzisa i-Rockwell Automation, njengoba i-ControlLogix 5000 yayingasekela yonke into epulatifomu eyodwa. Lokho kwasivumela ukuthi senze izinhlelo zibe zisezingeni elifanayo emazingeni aphansi,” kusho uBryant. “Kwasiza ukuthi ngaleso sikhathi, sihlanganise umsebenzi wokwenza izinto ngokuzenzakalela, ngochwepheshe abangu-45 ngaphansi komphathi oyedwa. Lowo mphathi wayefuna uhlelo olulodwa oluzosekela.”
Cishe ngaleso sikhathi, inkampani yahlela kabusha okuzenzakalelayo kwaba amaqembu amabili—elinye lokusekela imishini yokumba uwoyela ekhona (i-EOR), elinye lokuhlola, ukumba kanye nezinhlelo zokusebenza ezingavamile ezibizwa nge-BU. UBryant waba yingxenye ye-EOR, iCastillo ise-BU. “I-EOR yayinesabelomali esincane sonyaka sokushintsha ezinye izinto ngokushesha, kodwa ikakhulukazi ukushintshwa uma kwehluleka,” kusho uBryant. “Sasineziphaneli ezijwayelekile esasingazisebenzisa ngokushesha ukuze zithuthukiswe kanye nasemigodini emisha ekwazi ukuskena.
"Sinebhokisi le-CPU elijwayelekile, ibhokisi lokunikeza ugesi, kanye namabhokisi e-I/O akude emithombo, abahlukanisi kanye nokuhlolwa. Namuhla, sine-Rockwell Automation esithumelela amaphaneli aphelele, akhiwe efektri. Singathumela izinhlelo ezijwayelekile kuma-CPU ajwayelekile futhi sesikulungele ukuhamba."
Ngo-2017, iqembu le-BU lalifuna ukuthuthukisa indlela ejwayelekile yezicelo ezintsha nezingavamile. “Siphinde senze inani elikhulu lokubhoboza kanye nemithombo emisha enemigqa yokugeleza kanye nezindawo zokusebenza, ezinezidingo zazo,” kusho uCastillo. “Isikhathi siyimali kuleli bhizinisi—ukulibaziseka kosuku olulodwa noma ezimbili kubiza kakhulu kunezingxenye ezincane zezinhlelo zasensimini. Sidinga izinhlelo ukuthi zibe lula ukuzisebenzisa, futhi ziguquguquke, njengoba ukuzenzekela okujwayelekile kungasho izikhungo ezijwayelekile.”
Iqembu lalenza ngokwezifiso eziningi kakhulu zamaphaneli athile. Lalidinga izikhathi ezimfushane zokuhola kanye nekhono lokwenza izinguquko ezisheshayo sekwephuzile. “Sikhathazekile ngezindleko eziphelele zobunikazi (i-TCO), hhayi nje izindleko zokuqala eziphansi,” kusho uCastillo. “Sidinga ikhono lokunakekela, nokwengeza imishini, ukuthuthukiswa kanye ne-I/O kamuva. Kanye nochungechunge lokunikezela oluthembekile.”
Isitimela esivamile somthombo sizoba nezihlukanisi zemithombo kanye nemithombo, umshini wokuhlanza i-heater, amathangi kawoyela, amathangi amanzi, isiteshi sokudlulisa amanzi, i-gas scrubber, i-flare kanye ne-gas and oil metering, kanye namaphampu ahambisanayo, ama-valve kanye nezinsimbi.
Indlela ejwayelekile ye-BU ikhomba izidingo zokwenza izinto ngokuzenzakalela ngemishini (i-PLC noma i-Remote I/O); usayizi wokuvala—omncane, omncane, noma ophakathi; uhlobo (i-CPU kanye nokusethwa kwemodyuli); isisekelo/ukwandiswa (ubuningi bemodyuli); inguqulo; kanye negama lempahla (incazelo). Umphumela uba izinhlobo zemishini eziyisikhombisa ezingalinganiswa nezidingo. “Ungazihlanganisa ukuze uthole okudingayo,” kusho uCastillo. “Ungahamba nenguqulo eyisisekelo noma unikeze indawo yokwandisa noma ukwenza ngezifiso noma ukwengeza imishini.”
Baphinde balinganisa izinhlobo ezingu-11 zama-wire harnesses. “Kuthatha imizuzu ukuxhuma izintambo uma kuqhathaniswa namahora ukuze kutholakale izintambo, ngokulawula ikhwalithi engcono kanye nokusebenza kahle,” kusho uCastillo, “Futhi uma kunenkinga yokuxhuma izintambo, ungashintsha nje ikhebula.”
Uma sebeklame isitimela, uma kufika isitimela sesibili, bangamane bakopishe uhlelo. “Singaba namabhokisi ajwayelekile, akhiwe ngaphambilini esitokweni esikhundleni sokwakha amaphaneli enziwe ngokwezifiso,” kusho uCastillo. “Futhi ngokuhamba kwesikhathi, njengoba kuvela izinguqulo ezintsha kanye nama-processor, singathuthela kuzo ngakho-ke uma esidala siphelelwa yisikhathi, sesivele sazi ukuthi sizosishintsha ngani.”
Banemiklamo eyenziwe ngcono ngemibhalo engcono kanye nokuthengwa okulula. “Ngingashayela umthengisi ucingo ngithi ngifuna engu-20 yale mishini ezinyangeni eziyisithupha ezizayo,” kusho uCastillo. “Sinemishini esizoyisebenzisa endaweni yokwakha ukuze abasebenzi bakwazi ukuxhumana futhi bahlole konke ngokushesha.”
Ukuba nemishini efanayo yonke indawo kwenza kube lula ukuqeqesha abantu. Futhi, uma bethola emkhakheni ukuthi kunenkinga ngengxenye, njengebhulokhi yokugcina, bangayichaza kabusha futhi balungise uhlu lwezinto ezisetshenziswayo.
“Ukulinganisa kungasebenza kunoma iyiphi imboni, hhayi uwoyela negesi kuphela,” kusho uCastillo. “Kodwa, uma unezindlela ezingu-13 zokwenza izinto futhi unquma ukulinganisa, ungagcini unezindinganiso ezingu-14.”
Thola okungcono kakhulu ku-Automation Fair 2019 Abahleli be-Control bakhona ku-Automation Fair 2019 ukuze bakulethele izindaba ezishaqisayo, izinto ezintsha kanye nokuqonda okuvela kumcimbi. Uma umcimbi usuphelile, bazohlanganisa umbiko oqukethe izindaba eziphezulu. Oda ikhophi yakho kusengaphambili namuhla.
