Iterambere mu ikoranabuhanga ry'imashini zigaburira amatungo: Guteza imbere imikorere myiza n'ubwiza mu mirire y'amatungo ya none

Iterambere ry'amateka ry'imashini zigaburira

1.1 Kuva ku bikorwa byakozwe n'intoki kugeza kuri sisitemu zikora

Urugendo rwo guteza imbere imashini zitunganya ibiryo rugaruka ku bikorwa by'ibanze by'intoki aho ibikorwa byoroshye byo gusya, kuvanga no gusya byasabaga abakozi benshi kandi bigatanga ubushishozi buke. Iterambere rya mbere rikomeye mu ikoranabuhanga ryabaye hagati mu kinyejana cya 20 ubwo hatangizwaga imashini zitwara imizigo, inganda z'ibanze z'inyundo, n'imashini zivangavanga. Izi sisitemu za mbere, nubwo zari zigaragaza iterambere rikomeye ugereranyije n'uburyo bwo gukoresha intoki, zakomeje kugira ibibazo by'ubwiza bw'ibicuruzwa budahuye, ikoreshwa ry'ingufu nyinshi, n'ubushobozi buke bwo gukora.

Mu myaka ya 1980 habaye impinduka zikomeye aho habayeho uburyo bwa mudasobwa bugenzurwa bwatumye habaho gupima neza ibintu no gukurikirana imikorere y’ibikoresho. Ariko, ni impinduramatwara y’ikoranabuhanga yo mu kinyejana cya 21 yahinduye koko imashini zitanga ibiribwa muri sisitemu zigezweho tubona muri iki gihe. Inyubako zigezweho zitunganya ibiribwa ubu zihuza ikoranabuhanga ritandukanye harimo robots, artificial intelligence, internet of Things (IoT), na technology igezweho.

1.2 Ingingo z'ingenzi mu iterambere ry'ikoranabuhanga

Ibintu byinshi by'ingenzi byagaragaje iterambere ry'ikoranabuhanga ry'imashini zitanga ibiryo:

Izi ntambwe zatewe mu ikoranabuhanga zagabanyije amakosa y’abantu, zinoza imikorere y’ibicuruzwa, zinoza amahame y’umutekano, kandi zinoza cyane umusaruro mu nganda zitanga ibiryo ku isi.

Ibice by'ingenzi bya sisitemu ya none y'imashini zigaburira

2.1 Sisitemu zo Kwakira no Kubika

Sisitemu zigezweho zo kwakira amakuru zahindutse kuva ku gupakurura ibintu byoroshye n'intoki kugeza ku bisubizo bigezweho byikora birimo ikoranabuhanga ritandukanye. Imiyoboro igezweho yo kwakira amakuru ubu irangwamo:

• Sisitemu zo gupima ingero zikora ku buryo bwikorabakusanya ingero zigaragaza ireme kugira ngo bakore isesengura ryihuse ry'ubuziranenge
• Imbuga zipima ibintu zikoresheje ubwengehamwe n'ibipimo by'ubuhanga bushobora kubona impinduka z'agace gato
• Uburyo bwo kumenya ubushuhebihindura mu buryo bwikora ibipimo by'umuma hashingiwe ku miterere y'ibikoresho byinjira
• Gusuzuma ubwandugukoresha ibyuma bipima ibyuma, magnets, na X-ray systems kugira ngo ibikoresho fatizo bibe byiza

Ikoranabuhanga ryo kubika ibintu ryateye imbere mu buryo nk'ubwo hamwe n'iterambere rya:

• Silos zigezwehoifite ibikoresho byo kugenzura ubushyuhe, hamwe n'uburyo bwo guhumeka bwikora
• Sisitemu zo gucunga za mbere mu ikubitiro (FIFO)binoza ihindagurika ry'ibikoresho kandi bikarinda kwangirika kw'ibikoresho
• Gukurikirana imiterere y'ubuzimaikurikirana ubushyuhe, ubushuhe, n'ingano ya CO2 kugira ngo hirindwe kwangirika

2.2 Ikoranabuhanga ryo gusya no kugabanya ingano

Gusya ni imwe mu nzira zikoresha ingufu nyinshi mu gutunganya ibiryo by'amatungo, bigatuma kunoza imikorere y'ibiryo bigira akamaro cyane. Sisitemu zigezweho zo gusya zirangwamo:

• Gukurikirana ubuziranenge bwa pellet mu gihe nyacyohakoreshejwe uburyo bwo kureba n'ibikoresho bipima uburambe
• Imiterere ikoresha ingufu nkebigarura ubushyuhe bivuye mu gikorwa cyo gucukura

Uburyo bwo gusohora ibiryo byihariye (ubworozi bw'amafi, ibiryo by'amatungo) nabwo bwateye imbere mu buryo nk'ubwo:

• Ibikoresho byo gusohora ibikoresho bifite screw ebyiribitanga uburyo bwo kugenzura ibikorwa neza no koroshya
• Kugenzura neza ubushyuhe n'umuvudukokugira ngo intungamubiri zibungabungwe neza
• Sisitemu zo gukata zikoresha ikoranabuhangahamwe no gukurikirana no guhindura uburebure mu gihe nyacyo

Kwikora no Guhindura imikorere mu buryo bw'ikoranabuhanga

3.1 Imiterere ya sisitemu zo kugenzura

Inganda zigezweho zikoresha uburyo bugezweho bwo kugenzura buhuza ibice byinshi by’imikorere y’ikoranabuhanga:

• Igenzura ry'Ubugenzuzi n'Ikusanyamakuru (SCADA)sisitemu zitanga igenzura n'igenzura rusange

Izi sisitemu zituma abakora akazi bashobora gukurikirana no kugenzura inzira yose yo gukora baherereye ahantu hamwe, hamwe n'ibisubizo byikora ku bijyanye n'ihindagurika ry'imikorere no kwandika amakuru yose kugira ngo harebwe niba ireme ry'ikoreshwa ryayo rishoboka.

3.2 Isesengura ry'amakuru n'ivugurura ry'imikorere

Guhuza isesengura rigezweho bigaragaza intambwe ikomeye mu mikorere myiza y'ibiryo:

• Algorithm zo kubungabunga ibintu mbere y'igihebasesengura amakuru y'ihindagurika ry'ibikoresho, ubushyuhe, n'imikorere yabyo kugira ngo barebe ko byangirika mbere yuko bibaho.
• Uburyo bwo kunoza imikorerebahora bahindura ibipimo by'imikorere hashingiwe ku bipimo by'ubuziranenge mu gihe nyacyo
• Isesengura ry'ikoreshwa ry'ingufukumenya amahirwe yo kunoza imikorere
• Uburyo bwo guhanura ubuziranengegukoresha amakuru y'amateka kugira ngo hamenyekane imiterere y'umusaruro wa nyuma hashingiwe ku bikoresho fatizo byinjizwa

3.3 Guhuza IoT no Gukurikirana Kure

Ikoranabuhanga rya Internet of Things (IoT) ryahinduye uburyo bwo kubungabunga no gukoresha imashini zitanga amakuru:

• Gusuzuma indwara hakoreshejwe ikoranabuhanga rya kurekwemerera amakipe y'ubufasha mu bya tekiniki gusesengura imikorere y'ibikoresho aho ari ho hose ku isi
• Isesengura ry'ibiteganyijwe mbere y'igihegukoresha amakuru ya sensor kugira ngo hamenyekane ibikenewe mu kubungabunga no kunoza gahunda za serivisi
• Ibipimo by'imikorerekugereranya imikorere y'ibikoresho mu bigo byinshi
• Raporo yikoragukora inyandiko zijyanye no kubahiriza amategeko n'ibyemezo by'ubuziranenge

Ubu bushobozi bwagize akamaro kanini cyane mu gihe cy'icyorezo cya COVID-19, bituma habaho gukomeza gutanga ubufasha bwa tekiniki nubwo hari amategeko agenga ingendo n'amabwiriza yo kwirinda kwegerana.

Sisitemu zo kugenzura ubuziranenge no kwemeza

4.1 Gukurikirana Ubwiza mu buryo buboneye

Inyubako zigezweho zikora ibiryo by'amatungo zishyira mu bikorwa igenzura ryimbitse ry'ubuziranenge ku murongo:
