Uchungechunge amaswishi emboni angalawulwa okuthi, naphezu kokulula kwawo, abe nenani lemisebenzi ethuthukisiwe. Amaswishi ahlanganiswe kalula kunoma yiluphi uhlelo lwe-SCADA ngenxa yokusekelwa kwezivumelwano ezivulekile ze-Modbus TCP ne-SNMP, anokuvikelwa ekushintsheni okungalungile kanye nezinkomba zephutha kuphaneli yangaphambili ukuze kulungiswe iphutha kalula. Kukhona ukusekelwa kwephrothokholi ye-IEEE 802.3az, enciphisa ukusetshenziswa kwamandla kuze kufike ku-60%, futhi ukusebenza emazingeni okushisa adlulele ukusuka ku--40Β°C kuya ku-75Β°C kuvumela ukushintshwa ukuthi kusetshenziswe ezindaweni ezinzima kakhulu.
Esihlokweni, sizoqonda ukuthi ukushintshwa kwezimboni kuhluke kanjani kumaswishi e-SOHO yasendlini, sihlole imisebenzi yezimboni yedivayisi, futhi sicabangele inqubo yokusetha.
Izici zezimboni
Umehluko omkhulu phakathi kokushintshwa kwezimboni kanye nokushintshwa kwendlu yizidingo eziphakeme zokuthembeka uma usebenza kunoma yiziphi izimo. Amamodeli ezimboni anokuvikelwa kokuhlinzwa, ukushintsha imisebenzi yokuvikela amaphutha, kanye namathuluzi okulungisa izinkinga ngokushesha nezinkinga zokusayina. Izindlu zezinguqulo zezimboni zenzelwe ukumelana nemithwalo yemishini futhi zibe nendawo yokukhweza yesitimela ye-DIN evamile.
EKI-2000 uchungechunge
Uchungechunge lwamaswishi luhloselwe ikakhulukazi izikhungo ezincane lapho kungadingeki ukusetha imithetho yokushintsha nokuhlukanisa inethiwekhi kuma-VLAN. Amaswishi awanazo izilungiselelo futhi ayinketho engabizi kakhulu emugqeni wokushintsha we-EKI.
- enye yezimboni ezincane kunazo zonke emhlabeni. Ububanzi bayo obungu-2.5 cm nobude obungu-8 cm buvumela ukuthi ifakwe kalula kuma-switchboard ahlangene kakhulu, futhi umzimba wedivayisi wenziwe ngensimbi futhi unezinga lokuvikela le-IP40. ____________________________________________________________________________________
I-multifunctional gigabit PoE switch enamandla aphumayo afika ku-30W ngembobo ngayinye. Inezimbobo ezi-4 ze-SFP zokufaka amamojula okubona. Imodeli inesitifiketi sokuhambisana ne-European standard EN50121-4 sokufakwa kwezokuthutha ngololiwe. ____________________________________________________________________________________
EKI-5000 uchungechunge
Amadivayisi alolu chungechunge anezinketho ezengeziwe zokuhlanganiswa kumasistimu e-SCADA. Umsebenzi we-ProView ikuvumela ukuthi ugade isimo sembobo ngayinye usebenzisa izivumelwano ze-Modbus ne-SNMP. Izinketho ezithuthukisiwe zokuzihlola zedivayisi zisiza ukukhomba amaphutha okushintsha, futhi isitifiketi sokuphepha sikagesi sivumela iswishi ukuthi ifakwe ezindaweni eziyingozi.

- Okokufaka kwamandla ekhophi yasenqolobaneni kanye nesignali yokuhluleka kwamandla ahlukene
- Izinga lokushisa lisukela ku-40 kuya ku-75Β°C
Iswishi ingasetshenziswa njengesiguquli semidiya ukuhlanganisa imigqa yokubona nezintambo ezisontekile kumasayithi akude. Kukhona futhi amamodeli anosekelo lwe-PoE lokuxhuma ukubhekwa kwevidiyo nezinhlelo zokubona komshini.
Izinkomba zephaneli yangaphambili zibonisa isimo solayini wamandla ngamunye
Ukuphepha kukagesi nokuvikelwa kokuphazamiseka
Amaswishi ochungechunge lwe-EKI-2000 anokuvikela okwakhelwe ngaphakathi ekuphazamisekeni kwesikhashana kolayini bamandla afinyelela ku-3 4 volts, kanye nokuvikelwa ku-static voltage kolayini be-Ethernet afika ku-XNUMX XNUMX volts.
I-5000 Series iqinisekisiwe ukuthi i-ATEX/C1D2/IECEx-ubufakazi bokuqhuma futhi ingasetshenziswa eziqhumeni nasekufakweni kukawoyela negesi.
Amandla ekhophi yasenqolobaneni nesignali yephutha
Wonke amadivayisi ochungechungeni anokufakwa kwamandla okubili futhi akuvumela ukuthi uxhume ngokuhlukana umthombo wamandla oyisipele, isibonelo ebhethrini. Uma kwenzeka ukwehluleka kwamandla okuyinhloko, isistimu izoshintshela kumthombo wamandla oyisipele ngaphandle kokumisa ukusebenza, futhi ukudluliswa kwenkomba yokwehluleka kuzosebenza.
Uma kwenzeka kwephuka kwenye yemigqa yamandla, i-relay iyasebenza
Eyonga amandla i-Ethernet 802.3az ejwayelekile
Izinga le-IEEE 802.3az, elibizwa nangokuthi i-Green Ethernet, yakhelwe ukonga amandla, okubaluleke kakhulu ezindaweni ezithembele kumaphaneli elanga noma amandla ayisipele. Ubuchwepheshe bunquma ngokuzenzakalelayo ubude bokuxhunywa kwekhebula futhi bulungise amandla esignali adlulisiwe ngokusekelwe kulawa manani. Ngakho-ke, ekuxhumekeni okufushane amandla okudlulisela azoncishiswa uma kuqhathaniswa nemigqa emide. Izimbobo ezingasetshenzisiwe ziphelelwe amandla ngokuphelele.
I-Smart PoE
Amamodeli asekela i-PoE (Amandla phezu kwe-Ethernet) akuvumela ukuthi uqaphe amandla kagesi kanye nokusetshenziswa kwamanje kuchweba ngalinye usebenzisa iphrothokholi ye-Modbus. Ngokusebenzisa ukuqapha, ungathola izinguquko ekulayishweni okujwayelekile futhi ukhombe amaphutha omthengi, isibonelo, ukukhanya kwe-infrared okuhlulekile kwekhamera yokuqapha ividiyo.
Amafreyimu e-Jumbo
Wonke amadivayisi ochungechungeni asekela amafreyimu e-Jumbo, akuvumela ukuthi udlulise amafreyimu e-Ethernet afika ku-9216 bytes ngosayizi, esikhundleni samabhayithi ajwayelekile angu-1500. Lokhu kukuvumela ukuthi ugweme ukuhlukana lapho udlulisela amanani amakhulu edatha futhi, kwezinye izimo, kunciphisa ukubambezeleka kokudluliswa kwedatha.
Ukutholwa kweluphu
Ukushintsha okunokubona iluphu kuthola ngokuzenzakalelayo iphutha lokushintsha lapho izimbobo ezimbili zakha iluphu futhi zizivale ngokuzenzakalelayo ukuze kuvinjelwe ukuphazamiseka kwamanye amadivayisi axhunyiwe.
Amachweba lapho kutholwa khona iluphu amakwe ngenkomba ekhethekile ukuze atholakale ngokubukeka. Lesi sivikelo esilula nesisebenzayo sisebenza ngaphandle kwephrothokholi ye-STP/RSTP.
Isici se-ProView-ModBus ne-SNMP
Amaswishi ochungechunge lwe-EKI-5000 asekela isici sobunikazi se-ProView, esengeza ikhono lokuqapha impilo ngisho namaswishi angalawulwa. Ngokusekelwa kwezivumelwano ezivulekile ze-Modbus TCP kanye ne-SNMP, le nketho ikuvumela ukuthi uhlanganise iswishi kunoma iyiphi isistimu ye-SCADA noma iphaneli yokuqapha inethiwekhi. Idivayisi iyahambisana nohlelo lwe-Advantech kanye nohlelo lokuphatha inethiwekhi .
Idatha itholakala nge-SNMP ne-Modbus:
β’ Imodeli yedivayisi nencazelo oyikhethayo
β’ Inguqulo ye-Firmware
β’ I-Ethernet MAC
β’ Ikheli le-IP
β’ Izimo zembobo: isimo, isivinini, amaphutha
β’ Ivolumu yedatha edluliswayo ngamachweba
β’ Incazelo yembobo yangokwezifiso
β’ Ikhawunta yokunqamula isibali
β’ Isimo se-PoE/ukusetshenziswa kwamanje namandla kagesi (kumamodeli ane-PoE)
Yenza ngokwezifiso
Ukusetha kokuqala kungenziwa nge .
Ukulungiselelwa Kwekheli Le-IP
Kuthebhu ethi Uhlelo, ungasetha igama ledivayisi namazwana (leli gama nencazelo izotholakala nge-SNMP ne-Modbus), setha isikhawu sokuvala samaphakethe e-modbus, futhi uthole inguqulo ye-firmware.
isiphetho
Shintsha uchungechunge iyisixazululo esilula futhi ngesikhathi esifanayo esisebenzayo kumasayithi amancane akude. Isibonisi sephaneli yangaphambili ikuvumela ukuthi uhlole ngokushesha izinkinga ngaphandle kokubandakanyeka kwabasebenzi abaqeqeshiwe. Ukusebenza okuphezulu kwezinga lokushisa kanye nezindlu ezimelana nomthelela kuvumela amadivayisi ukuthi asetshenziswe ezindaweni ezinokhahlo.
