Isikhombisi sefayibha yase-indistri sinemisebenzi encane eyancane edizajeni ngokwesiko kwezindawo zase-indistri eziphaphamile. Lolu hlelo lobunjwa olukhulu lwenza ukuguqula nokuthumela amanani kuzwire yesithwe sefayibha, libonisa ukubaluleka nokusebenza okuphezulu ematheni aphaphamile. Isikhombisi senzakalela izimo ezifanayo nezindlela zokunyusa izindlela, izindlela eziphezulu zokusebenza okungenani phansi kuka -40°C ukuya ku-75°C, nezinsekezo eziphethwe ze-eletromagnetikhi (EMI). Lezi sikhombisi zinikeza izimiso zase-indistri ezahlukeneyo bese zenikeza izindlela eziningi zokuhlanganisa, liba lelithuba lokuthiwalwa kwekhweyenda elisebenzela. Yenziwe ngezinto ezijwayelekile yase-indistri, zibanjwa ukusebenza ngokuphelele ematheni aphathekayo, iphufu, nezimo eziphaphamile. Itheknoloji yesithwe sefayibha ye device yenziwa ukuthumelana namanani kude kunesithwe esilinda sokuthunga isiqiniseko nezimali. Izikhombisi zase-indistri ezisha futhi zinezimiso zokuphatha njengekhipha VLAN, izilungiselelo zeQoS (Inqanawa Yokusebenza), nezinhlelo zokuhlola khweyenda. Zinemisebenzi ethembekile kakhulu kwezixhobo zase-indistri, ukudluliselwa okujwayelekile, nezinye iindlela eziphambene nawo apho ukubaluleka kakhulu kakhulu kwebandla nezisebenza okudingeka kuzobe kube yimaliphi.

Izishayeli zemoto zindaba zinikeza izinkomba eziningi ezingcono ezingavumelelwa kuzo emasipheke esemlekile. Okokuqala, ukwehla kwabo kuhlinzekisa ukulaleka nokuthobela okuphakade, noma emaphakamini amaningi. Izishayeli zinamathuba wezilimi zokunqunyelwa yokusebenza ngokuvamile, ayingeni ishoki, ukuxhumeka nokukhanya okuphezulu, okwenza ukunciphisa kakhulu imimandla yokuhlola nokuthungatha. Isisekelo sefayibha yemoto sikhombisa ukuvikela okuphakade kwekhwankhwa lemfikiso yeletromagnetiki, lokho kwenza ukuthi izishayeli zibe yimali emareshini amaningi nezilimi zokumisa imoto. Enye indlela enjengo inkomba yokuthula kukuthi ifayibha yemoto iyenziwe ngendlela engavumi ukuthatha inqubo yekhompyuta ngaphandle kokuboniswa. Izishayeli zisenze idatha ithathele kude ngaphandle kokuchithwa komkhawulo, okwenza ukuthi ikhonkco lithule njengoba lingenayo imigomo yesinfomu. Zinikeza futhi izinkumbanelo zokuphatha okuphezulu, ekuvunyelisa ukulandelelwa nokugcina idatha ngokushesha, lokho kwenza ukuthula kwekhonkco nokulungisa izinkinga. Imibandela yenkqubo yezindleko nezimo zokucoca ngokuzenzekela ziyenza ukuthi isebenze ngokuvamile, okudingekile ukuvikela ukusebenza ngaphandle kokuthungatha. Izishayeli zinhlanu izimo zaseziphelo nezinye iiprothokholi zokusebenza, zenza ukuthi zingxwarwe nezilimi ezisemwakameni nezinto ezengeza ngokuzayo. Ukwehla kwabo okuncane nezinethiwe zokufaka phansi zikhomba ukuthula kwezifakelo, ngesikhathi esifanayo ukusebenza kwabo ngaphandle kokumemeza kwenza ukuthi inkomba yokuhlola inciphe nekuhlise ukuthobela. Inkinobeko yokudala amaqela afanayo nezikhathi zokuzalisa ngokushesha zikhombisa ukuthobela kwekhonkco, ngesikhathi esifanayo ukusebenza kwabo ngokwempilo yokusemelana nokulinganisa kwezimpawu zokusebenza ziyenza ukuthi zidingele izimpawu eziphambene nemisebenzi yaseziphelo.

Ukunikezwa kwezinhlanhla zokusebenza ngokuthi yilayini

Ukunikezwa kweqhamuka lefule lithintekile kakhulu kusuka kudizayini yabo enkululeko nezindawo zokuphepha. Lomkhumbi ngamunye uphansi komhlaba wemigomo yokuthi uqiniseke ukusebenza kwazo kuzindlela ezikhuluma, noma izinto eziyimfuneko zokuhlanganisa amandla kanye nokuphephwa kwezinye izinhlanhla. Umlayezo wamagugu weqhamuka unikeza ukuphepha kwi-IP30 kungcolweni nezulu, futhi udizayini awunayo ifani elimitha kumele kuhlale kahle. Iindlela ezimbili zokunikeza amandla ngekunikezwa kwayo okungu-nyana kumele kuhlale kahle noma kungekho amandla. Isiqinisekiso sezigaba zokusebenza ngokushesha sigcina ukuthi siyavumelana nezimo eziphambene nezinhlanhla, ukuxhumeka, nezinhlanhla. Lokhu kunikeza ukunciphisa izindleko zokuphila futhi kude kube lula ukuba kunezinsuku ezidinga ukusebenza, lokhu kuyindlela engcono yokusebenzela kuzo zinhlanhla ezingcono zokusebenza apho ukusebenza ngokugcwalisa kudingeka.

Imikhwelo Efanayo Yokuphepha Kwemidwebo

Izimo zokuphatha kahle kwezithingi zemifanekiso yasezindaba zenkampani zinikeza ubukhulu obungadlulanga komsebenzi wamanje. Isikrini esihlelwa ngokuzenzakalelayo kunye neWeb sinezimalyelo ezingcono yokuseta nokugcina ulwazi oluhlanganayo, nangona inkxenye yeSNMP iyenzela ukuxhunyaniswa kwamanje kumathini okuphathi manje. Iindlela ezininzi zokuhlola zinceda ekutholeni nokulungisa iingxaki zamanje ngokukhawuleza, zikhethe isikhathi esidingekayo sokulungisa iingxaki. Ithuli inxalenye yeVLAN ngokweengcamango ezahlukeneyo yokwahlula amanje kunye nokuphephileyo, nangonye neQoS engqamene neempawu zombhalo ukuze idatha ebalulekeke inikezelwe inkqubo yokusebenza ngaphambili. Inkxenye yophandlelo oluyilayilo ngemigca emhlophe edlula ngaphezu kwe20ms iyenzelula ukuba manje ingaqhamanga, nangonye imigca yokuchupa iphawntu eyenza kube leliko ukugcina manje kunye nokulungisa iingxaki. Lezi zimo zokuphatha zizonke zibandakanya ukwenza ummandla wamanje oqondile kwaye uyiseleyo.

Ukuxhunyiswa Olusempandeni

Izishayeli zemikhombiso yasezimali ziyindlela ngokuthi zenze ukuxhumeka kwezimali nezemikhombiso esezakhiweni. Iqinisekisa ukusebenza namanqaku amaningi asemandleni okunxibelelana ngqo ne-PLCs, i-SCADA systems, kunye nezixhobo zokuzivocavoca. Iizishayeli zinezinye iimatyhubhu ezikhethiweyo zemikhombiso ozinga ukuba neendawo ezahlukeneyo zokugcina kwaye ukuba nenqanaba lefuthelelwano kwi detheni. Iindlela zokufaka ngaphandle kwe-DIN-rail kunye neencamathiswano encinci zenze ukufakwa ngemfutshane kwiingcindezi kunye nezinxaseni zasezimali. Iizishayeli zisenokusebenza ukubala okutombo kunye nokulungisa ngokuzenzekelayo, ukuyila kwezinye iindawo kunye nokuhlinzela detheni. Inokusebenza kwiiprothokholi eziphantsi kwaye ziphezulu zokunxibelelana iqinisekisa ukuthi zingenakuhluka ngelixa kungenza amanyathelo etsha yokuvuselela detheni. Le mikhwanxa iyenza kube lula lokusebenzisa kwiindlela eziphanda njalo kunye nokuvakalela detheni ezivele ezigciniweyo.
