I-Programmable Logic Controller (PLC) iwuhlelo lwe-elekthronikhi olusebenza ngedijithali olwakhelwe ngqo izinhlelo zokusebenza ezindaweni zezimboni.Isebenzisa inkumbulo ehlelekayo ukuze igcine imiyalelo yokwenza imisebenzi enengqondo, ukulawula okulandelanayo, isikhathi, ukubala, nokusebenza kwezibalo ngaphakathi kwayo.Ilawula izinhlobo ezahlukene zemishini eyimishini noma izinqubo zokukhiqiza ngokusebenzisa okokufaka nokuphumayo kwedijithali noma kwe-analog.
I-Programmable Logic Controller (PLC) isilawuli se-arithmetic yedijithali esine-microprocessor yokulawula okuzenzakalelayo, engagcina futhi isebenzise imiyalelo yokulawula kunkumbulo yomuntu noma kunini.Isilawuli esihlelekayo sakhiwe amayunithi asebenzayo afana ne-CPU, inkumbulo yokufundisa nedatha, isixhumi esibonakalayo se-input/output, ukunikezwa kwamandla, ukuguqulwa kwedijithali ukuya kwe-analog, njll. Ezinsukwini zakuqala, izilawuli zokuqonda ezihlelekayo zazinomsebenzi wokulawula okunengqondo kuphela, ngakho-ke zaqanjwa ngokuthi izilawuli ezinengqondo ezihlelekayo.Kamuva, ngokuthuthuka okuqhubekayo, lawa mamojula ekhompiyutha anemisebenzi elula ekuqaleni ayenemisebenzi ehlukahlukene, ehlanganisa ukulawula okunengqondo, ukulawula isikhathi, ukulawula kwe-analog, nokuxhumana kwemishini eminingi.Igama liphinde lashintshwa laba Isilawuli Esihlelekayo, Nokho, ngenxa yokungqubuzana phakathi kwesifinyezo se-PC nesifinyezo se-Personal Computer, futhi ngenxa yezizathu ezivamile, abantu basavame ukusebenzisa igama elithi isilawuli se-programmable logic, futhi basasebenzisa isifinyezo esithi PLC.Ingqikithi yesilawuli se-PLC esihlelekayo siyikhompyutha ezinikele ekulawuleni izimboni.Izingxenye zayo eziyisisekelo zifaka: imojula yokunikezela amandla, imojula ye-CPU, inkumbulo, imojula yokufaka ye-I/O ne-output, i-backplane ne-rack module, imojula yokuxhumana, imojula yokusebenza, njll.
I-PLC Programmable Logic Controller: I-PLC yaziwa ngokugcwele ngokuthi Isilawuli Sengqondo Ehlelekayo ngesiNgisi kanye nesilawuli esinengqondo esihlelekayo ngesiShayina.Ichazwa njengesistimu ye-elekthronikhi esetshenziswa ukusebenza kwedijithali, eklanyelwe ukusetshenziswa ezindaweni zezimboni.Isebenzisa isigaba senkumbulo ehlelekayo ukuze igcine izinhlelo ngaphakathi, isebenzise imiyalelo eqondiswe kumsebenzisi efana nokusebenza okunengqondo, ukulawula okulandelanayo, isikhathi, ukubala, nokusebenza kwe-arithmetic, nokulawula izinhlobo ezahlukene zezinqubo zomshini noma zokukhiqiza ngokusebenzisa okokufaka/okuphumayo kwedijithali noma kwe-analog.I-DCS Distributed Control System: Igama eligcwele lesiNgisi le-DCS i-Distributed Control System, kuyilapho igama lesiShayina eliphelele lithi I-Distributed Control System.I-DCS ingahunyushwa njengomkhiqizo ozenzakalelayo wobuchwepheshe obuphezulu osetshenziswa kakhulu ezimbonini lapho kukhona izilawuli eziningi ze-analog loop, ezinciphisa ubungozi obubangelwa ukulawulwa, kanye nokuhlanganisa ukuphatha kanye nemisebenzi yokubonisa.I-DCS ngokuvamile iqukethe izingxenye ezinhlanu: 1: isilawuli 2: I/O ibhodi 3: indawo yokusebenza 4: inethiwekhi yokuxhumana 5: isofthiwe yezithombe nezinqubo.
1. Imojula yamandla, enikeza amandla okusebenza angaphakathi okusebenza kwe-PLC, futhi amanye anganikeza amandla amasignali okokufaka.
2. I-CPU module, okuyiyunithi yokucubungula emaphakathi ye-PLC, iwumongo wehadiwe ye-PLC.Ukusebenza okuyinhloko kwe-PLC, njengejubane nesikali, kubonakala ngokusebenza kwayo;
3. Inkumbulo: Igcina ikakhulukazi izinhlelo zabasebenzisi, kanti ezinye zinikeza inkumbulo yokusebenza eyengeziwe yohlelo.Ngokwesakhiwo, inkumbulo inamathiselwe kumojula ye-CPU;
4. I-module ye-I/O, ehlanganisa izifunda ze-I/O futhi ihlukaniswe ngamamojula emininingwane ehlukene ngokuya ngenani lamaphoyinti nohlobo lwesekethe, okuhlanganisa i-DI, DO, AI, AO, njll;
5. I-Base plate kanye ne-rack module: Ihlinzeka nge-base plate yokufakwa kwamamojula ahlukahlukene we-PLC, futhi inikeza ibhasi lokuxhuma phakathi kwamamojula.Ezinye izindiza ezingemuva ziyasetshenziswaamamojula esixhumi esibonakalayo kanti amanye asebenzisa imigwaqo yebhasi ukuze axhumane.Abakhiqizi abahlukene noma izinhlobo ezahlukene zama-PLC avela kumkhiqizi ofanayo azifani;
6. Imojula yokuxhumana: Ngemva kokuxhuma ku-PLC, ingenza i-PLC ixhumane nekhompyutha, noma i-PLC ixhumane ne-PLC.Okunye futhi kungafinyelela ukuxhumana nezinye izingxenye zokulawula, njengeziguquli zefrikhwensi, izilawuli zezinga lokushisa, noma bakhe inethiwekhi yendawo.Imojula yokuxhumana imele amandla okuxhumana e-PLC futhi imele isici esibalulekile sokusebenza kwe-PLC namuhla;
7. Amamojula asebenzayo: Ngokuvamile, kunamamojula wokubala anesivinini esikhulu, amamojula okulawula isikhundla, amamojula okushisa, amamojula e-PID, njll. Lawa mamojula anama-CPU awo angakwazi ukucubungula kusengaphambili noma ukuthumela amasignali okucubungula ukuze enze lula ukulawula kwe-PLC CPU kwezilawuli eziyinkimbinkimbi ezihlelekayo. .Izinhlobo nezici zamamojula ahlakaniphile nazo zihluke kakhulu.Kuma-PLC asebenza kahle, lawa mamojula anezinhlobo eziningi nokusebenza okuhle.
