Isingeniso Kumlawuli Osetshenziswa Ku-Automatic Cummins Genset

Njengamanje, iziteshi zokudlulisela zokuxhumana nge-microwave ezingenamuntu, iziteshi zesathelayithi kanye ne-optical fibre communication kanye nezinye iziteshi ezikhethekile zemvelo zikadizili ezakhiwe ezintabeni, ezindaweni eziwugwadule, ogwadule nasezindaweni ezomile ezisezintabeni ikakhulukazi zisebenzisa amasethi ejeneretha kadizili angenamuntu ngokuphelele.Uma amandla okusebenza engajwayelekile, iyunithi ingafakwa ekusebenzeni ngokuzenzakalelayo.Iphaneli yokulawula okuzenzakalelayo ivamise ukuhlonyiswa ngesilawuli se-microcomputer se-EGT1000 esikhiqizwe yi-Canada STATICRAFT, isilawuli se-microcomputer se-MEC20 esikhiqizwe yi-Canada TTI (THOMSON) noma isilawuli se-OMRON se-PLC esikhiqizwe yi-Japan SYSMAC.Nasi isingeniso esifushane sesilawuli se-microcomputer se-EGTIOOO.

Isilawuli esizenzakalelayo se-microcomputer se-EGT1000 esisetshenziswa kusethi yejeneretha kadizili ye-Cummins.Isilawuli singaqedela ukulawula okuzenzakalelayo, ukuvikela okuzenzakalelayo kanye imisebenzi yokuqapha ekude .Idatha yokusebenza kwesistimu namasiginali okuqapha kungathunyelwa esikhungweni sokuqapha ngemigqa eminingi ezinikele, ukuxhumana kwe-RS232, amamodemu nezintambo zocingo.Uhlelo lokulawula lunikeza zonke izinqubo zokuxhumana.Abasebenzisi bangahlanganisa isofthiwe yokuqapha ngokwabo, futhi basethe imingcele yokuqapha esikrinini sokulawula ngekhibhodi, noma basethe imingcele yokuqapha kusayithi noma bekude ngesofthiwe yekhompyutha.Iphaneli yokulawula iphinde ifakwe i-switch yokudlulisa enokwethenjelwa kakhulu, enamadivayisi axhumene kagesi kanye nemishini ukuze kuqinisekiswe ukuguqulwa okuthembekile phakathi kweyunithi namapayipi amakhulu.Iphaneli yokulawula ifakwe ne-voltage regulator bypass switch kanye ne-load shunt switch.

(1) Okokufaka nokuphumayo

Ngokungeziwe kungcindezi evamile kawoyela, ukukhuphuka kwezinga lokushisa kweyunithi namatheminali okukhipha amandla kawoyela webhethri, isilawuli se-EGT1000 siphinde sibe namatheminali okokufaka achazwe ngabasebenzisi angu-4 kanye namatheminali angu-8 achazwe umsebenzisi.Ukwengeza isignali yokulawula kutheminali yokokufaka kungabona ukuqala kwerimothi nokuvalwa kwesethi yejeneretha yedizili.Itheminali ngayinye ephumayo ingakhipha amasiginali anjengamandla amapayipi avamile, ukusebenza kwenjini kadizili evamile, ukwehluleka kwenjini kadizili, ukwehluleka kwesekethe yokushaja ibhethri, kanye nokwehluleka kwesekhethi yeyunithi ye-DC.

(2) Isibonisi ne-alamu

Isilawuli se-EGT1000 singabonisa i-voltage eyinhloko yezigaba ezintathu, iyunithi ye-voltage ephumayo yesigaba sesithathu kanye nomthwalo wamanje wezigaba ezintathu ngasikhathi sinye.Ingaphinda ibonise imvamisa yama-mains kanye ne-voltage ephumayo yesethi yejeneretha yedizili.Ingakwazi futhi ukubonisa ukwehluleka kwenjini ye-diesel kanye nembangela yokwehluleka, futhi iqale ibhethri.Izimo zephutha ezifana nokwehluleka, ukwehluleka kwesekhethi yokushaja kweyunithi, izinga likawoyela eliningi noma eliphansi ethangini likaphethiloli, umfutho ophansi kawoyela wokugcoba kanye nokukhuphuka kwezinga lokushisa okweqile kweyunithi, kanye nesignali ye-alamu yephutha izokhishwa ngesikhathi esifanayo.

(3) Insimbi

Kuphaneli yokulawula, ngaphandle kwe-EGT1000 ingabonisa amapharamitha ahlukahlukene, ifakwe ne-DC voltmeter, i-ammeter ye-DC, igeji yokucindezela kawoyela wenjini kadizili kanye negeji lokushisa likaphethiloli ukubonisa imingcele ehlukahlukene yobuchwepheshe.

4) Izici eziyinhloko zesilawuli se-EGT1000

① Ukuboniswa kwedijithali kwawo wonke amapharamitha nokuboniswa kombhalo kwembangela yokwehluleka.Kubalawuli abahlukahlukene bendabuko, kunezinkomba eziningi futhi izinkomba ezihlukahlukene ze-alamu ziyinkimbinkimbi kakhulu.Isilawuli sekhompiyutha encane ye-EGT1000 sinesikrini sokubonisa umkhiqizo owuketshezi wezinhlamvu ezingu-40 esinemigqa emibili, esingabonisa amapharamitha amaningi obuchwepheshe ngesikhathi esisodwa futhi asidingi ukushintsha kokukhetha.Uma isethi yejeneretha yedizili yehluleka, isibonisi sizophinde sibonise ngokushesha imbangela yokwehluleka embhalweni.Ngakho-ke, abasebenzi bokusebenza nokunakekela bangakwazi ukuxazulula izinkinga ngokushesha nangokunembile.

②Isilungiselelo sepharamitha silula, sifanelekile futhi sinembile.Isilawuli se-microcomputer se-EGT1000 samukela okokufaka okuqondile kwesitayela semenyu.Amapharamitha ahlukahlukene angabhalwa ngokuqondile ngekhibhodi, futhi angafakwa kukhompuyutha ekude ngohlelo lokuxhumana lwe-RS232.Asikho isidingo sokusebenzisa amakhodi kanambambili noma i-octal okunzima ukuwakhumbula ukusetha amapharamitha ahlukahlukene.Imikhawulo ye-voltage kagesi iphezulu kakhulu noma iphansi kakhulu futhi imvamisa iphezulu kakhulu noma iphansi kakhulu ingasethwa noma ilungiswe ngokushesha nangokunembile ngokwezidingo ezahlukene zemishini yezokuxhumana.

③Ukuqapha sekuthuthukile, futhi izingxenye zokulawula zihamba ngokushesha nangokuthembekile.Ngenxa yokusetshenziswa kwama-microprocessors athuthukile ukuqapha isimo sokuphakelwa kwamandla okulindile, izingxenye zokulawula zisebenza ngokushesha nangokuthembekile, ezingaqinisekisa ukuthi ukunikezwa kwamandla kweyunithi kanye nokunikezwa kwamandla kagesi okuyinhloko kuyashintshwa ngesikhathi esingcono kakhulu.Isilawuli se-microcomputer se-EGT1000 asikwazi ukuqapha i-voltage kanye nemvamisa yama-mains kanye amasethi generator diesel , kodwa futhi i-engeli yesigaba salokhu okubili.Uma umehluko wesigaba phakathi kokubili ususondele ku-zero, umthwalo uyashintshwa.Ngakho-ke, lapho umthwalo ushintshwa phakathi kwamapayipi amakhulu kanye nesethi yejeneretha yedizili, empeleni awuzwakali.

Isilawuli se-EGT1000 siqukethe ama-relay ahlukahlukene, akukho uxhumano lwangaphandle oludingekayo, umjikelezo ulula, futhi ukwethembeka kuphezulu.Kulolu hlelo, izinyathelo ezihlukahlukene ezifana nokuhlukaniswa kukagesi kanye ne-photoelectric nazo zamukelwa, ezingagwema ngokuphumelelayo ukuphazamiseka kwezibonakaliso zangaphandle ohlelweni lokulawula.Ngaphezu kwalokho, isilawuli sisebenzisa ugesi weziteshi eziningi ukuze siqinisekise ukusebenza okungaphazamiseki kwesikhathi eside.Isilawuli siphinde sisebenzisa iphasiwedi yezendlalelo eziningi ukuze siqinisekise ukuphepha kohlelo.Ngisho noma ingasetshenziswanga kahle, ngeke ibangele ukwehluleka kokulawula.
