Esikhathini se-Industry 4.0 nokukhiqiza okuhlakaniphile, amamojuli ekhamera asebenza njenge-"amehlo" ezinhlelo ezizenzakalelayo, avumela izicelo ezisukela ekuhlolweni kwekhwalithi nombono womshini kuya ekulandeleni ukunyakaza nokuqapha inqubo. Kodwa-ke, ukusebenza kwamamojuli ekhamera lawo kuhle kuphela njengesixhumi esixhuma kuzo kwezinye izinhlelo. Ezinye zezixhumi ezivame kakhulu ezimboniniamamojuli ekhamera namuhla yi-Industrial Ethernet (isibonelo, i-GigE Vision, i-Ethernet/IP) kanye ne-USB3.0 (kuhlanganise ne-USB3.1 Gen 1).
Nakuba zombili zingadlulisela idatha yesithombe enencazelo ephezulu, ukufaneleka kwazo kuyahlukahluka kakhulu kuye ngokuthi zisetshenziswa kanjani. Imibhalo eminingi igxila kuphela kwimicikilisho yobuchwepheshe, kodwa lesi sihloko sisebenzisa indlela ehamba nezigameko—sikusize udlule emicikilishweni ukuze ukhethe isixhumanisi esilungile ngokusekelwe ezidingweni zakho ezihlukile zezimboni, imigomo yokukhula, nemikhawulo yemvelo. Ekugcineni, uzoba nenkambiso ecacile yokunquma ukuthi i-Industrial Ethernet noma i-USB3.0 iyisinqumo esihle kakhulu sokufakwa kwemojuli yekhamera yakho.
1. Ukuqonda Indima Eyinhloko Yezixhumanisi Kumamojuli Amakhamera Embonini
Ngaphambi kokungena ekuqhathanisweni, kubalulekile ukuqaphela ukuthi kungani isixhumanisi sibalulekile kumamojuli amakhamera embonini. Ngokungafani namakhamera abasebenzisi (lapho ukusebenziseka kalula kuvame ukuba ngaphambili), amamojuli amakhamera embonini adinga ukwethembeka ezindaweni ezinzima, ukubambezeleka okungaguquki ukwenza izinqumo zesikhathi sangempela, i-bandwidth yokuthwebula izithombe ezinezinga eliphezulu kanye nesinqumo esiphezulu, kanye nokukala ukuhlanganisa nezinhlelo eziyinkimbinkimbi zokuzenzakalela.
I-interface isebenza njengobhulo phakathi kwesenzisi sesithombe sekhamera kanye nesilawuli esamukelayo (isibonelo, i-PC, i-PLC, noma idivayisi yokubala esezingeni eliphezulu). I-interface engahambelani ingaholela ekulahlekelweni kwezithombe, ukubambezeleka kokudluliswa kwedatha, ukuvalwa kwesistimu, noma ngisho nokuhluleka kokuhlolwa—kudla abakhiqizi isikhathi nemali. Ngalokhu engqondweni, ake sihlukanise ukuthi i-Industrial Ethernet ne-USB3.0 ziqhathaniswa kanjani nezidingo zezimboni.
2. Ukuqhathaniswa Okubalulekile Kwezobuchwepheshe: I-Industrial Ethernet vs. i-USB3.0
Ukubeka isisekelo, ake siqhathanise izincazelo eziyinhloko zobuchwepheshe ze-Industrial Ethernet (sigxile ku-GigE Vision, okuyindinganiso ye-industrial Ethernet esetshenziswa kakhulu emakhamera) ne-USB3.0. Qaphela ukuthi nakuba i-Industrial Ethernet ihlanganisa ezinye izindinganiso (isibonelo, i-PROFINET, i-Ethernet/IP), i-GigE Vision iqhathaniswa ngqo ne-USB3.0 ezinhlelweni zamamojuli ekhamera ngenxa yokugxila kwayo embonini yokubona imishini.
Ipharamitha Yezobuchwepheshe | I-Industrial Ethernet (GigE Vision) | USB3.0 (USB3.1 Gen 1) |

Ngenkathi le micu inikeza isisekelo, isinqumo sangempela sincike ekutheni isikhombimsebenzisi ngasinye sihambisana kanjani nesimo sakho esithile sesicelo. Ake sihlole izimo ezivame kakhulu zezimboni nokuthi yisiphi isikhombimsebenzisi esiphumelela kakhizi.
3. Isimo 1: Umbono Womshini Wesivinini Esiphezulu, Ibanga Elifushane (isb., Ukuhlola Komugqa Wokuhlanganisa)
Izicelo eziningi zezimboni zibandakanya ukuhlola okuseduze, okwesivinini esiphezulu—njengokuhlola amaphutha ezingxenyeni zikagesimende (isb., amabhodi wesifunda) noma ukuqinisekisa ukupakishwa komkhiqizo kumugqa wokuhlanganisa osheshayo. Kulezi zimo, ikhamera ivame ukufakwa kungakapheli amamitha ama-5 kusuka kumphathi womsingathi, futhi into ebaluleke kakhulu ukukhulisa isivinini sohlaka nesinqumo ngaphandle kohlaka oluwile.
I-USB3.0 yenza kahle lapha ngezizathu eziningana. Okokuqala, i-bandwidth yayo engu-5 Gbps ilungele amakhamera anokulungiswa okuphezulu (isib. i-4K) kanye ne-frame rate ephezulu (isib. i-60 FPS)—inikeza ukudluliswa okwanele ukudlulisa idatha yesithombe engacindezelwanga ngesikhathi sangempela. Okwesibili, i-latency ephansi ye-USB3.0 (efana neye-GigE) iqinisekisa ukuthi idatha yesithombe ifinyelela umphathi ngokushesha, ivumela izinqumo ezisheshayo zokuhlola (ezibalulekile ukumisa umugqa uma kutholwa iphutha).
Ngaphezu kwalokho, izindleko eziphansi zokuqala ze-USB3.0 ziyenza ilungele ukusetshenziswa okuncane kuya kokumaphakathi (isib. amakhamera angu-1-4 kumugqa ngamunye). Ukusebenza kwayo kwe-plug-and-play kwenza ukulungiswa nokugcinwa kube lula, kunciphisa isikhathi sokungasebenzi kumigqa yokuhlanganisa ematasa. Kodwa-ke, kubalulekile ukuqaphela ukuthi umkhawulo wekhebula we-USB3.0 wamitha angu-5 uyisithiyo esiqinile lapha—uma ikhamera yakho idinga ukubekwa ngaphezu kwamitha angu-5 ukusuka kumphathi, i-USB3.0 ayisebenzi ngaphandle kwezandiso ezisebenzayo (ezingeza ubunzima nezindleko).
Nini ukukhetha i-Industrial Ethernet kulesi simo: Kuphela uma udinga ukuxhuma amakhamera angaphezu kuka-4-6 kumphathi oyedwa, noma uma ukwanda esikhathini esizayo (isib. ukwengeza iziteshi zokuhlola) kuyinto ebalulekile.
4. Isimo 2: Izinhlelo Zokuthwebula Ezinkulu, Ezisatshalaliswe (isib. Ukuzenzakalela Kwesitolo Esikhulu)
Ukuzenzakalela kwesitolo esikhulu, amavolvo ahlakaniphile, kanye nemisebenzi emikhulu yezinto ezithunyelwa ngaphandle ngokuvamile kudinga amamojuli amaningi ekhamera asatshalaliswe endaweni ebanzi (isib. amamitha angu-50-100 ukuhlukana). Lezi zinhlelo zidinga ukuhlanganiswa neminye imishini yezimboni (isib. izithwali, amarobhothi, ama-PLC) futhi zidinga ukusebenza okungaguquki kuwo wonke amakhamera.
I-Industrial Ethernet (i-GigE Vision noma i-10GigE) iyona ekhethwa kakhulu lapha. Ibanga layo lokudlulisa elingamamitha angu-100 (nezingcingo ezijwayelekile ze-Cat5e/Cat6) likuqeda ukudingeka kwezinto zokwelula ezibizayo, kanti izingcingo ze-fiber optic zingalwelula leli banga lifike ku-10 km ezinhlelweni ezidinga ibanga elide. Ukusekelwa kwe-Industrial Ethernet kwe-Quality of Service (QoS) kuqinisekisa ukuthi idatha yesithombe ipriority ngaphezu kwezinye izinto zenethiwekhi (isb., idatha yenzwa), kuvimbela ukwanda okungazelelwe okungaphazamisa imisebenzi yesikhathi sangempela.
Ukukala nakho kungenye inzuzo enkulu. Amanethiwekhi e-Industrial Ethernet angasekelwa amamojula ekhamera amakhulu (nezinye izinto) kunethiwekhi eyodwa ngama-switch, okwenza kube lula ukwelula uhlelo njengoba umsebenzi wakho ukhula. Ngaphezu kwalokho, i-Industrial Ethernet yakhelwe ukuthi ihlangane kahle nezinye izivumelwano zezimboni (isb., i-PROFINET, i-Ethernet/IP), okwenza ukuthi kube nokulawulwa okuyinhloko kohlelo lonke lokuzenzakalela.
I-Power over Ethernet (PoE) iyinzuzo eyengeziwe ezinhlelweni ezisatshalalisiwe—ivumela amamojuli ekhamera ukuthi athole amandla nedatha ngekhebula elilodwa, yehlisa izindleko zokufaka futhi yeqe isidingo samandla ahlukene ezindaweni ezinzima ukufinyelela kuzo. I-USB3.0, ngokungafani, inemikhawulo ngobude bekhebula layo nokukala kwamadivayisi, okwenza ingasebenzi ezindaweni ezinkulu ezisatshalalisiwe.
5. Isimo 3: Izindawo Zezimboni Ezinzima (isb., Ukukhiqizwa Kwezimoto, Ukuthwebula Ngaphandle)
Izimboni zezimoto, izindawo zokuncibilikisa insimbi, kanye nezicelo zokuthwebula ngaphandle (isb., ukuqapha indawo yokwakha) ziveza amamojuli ekhamera ezimeni ezinzima: izinga lokushisa elidlulele (-40°C kuya ku-85°C), ukuphazamiseka kukagesi (EMI) okuvela emishinini esindayo, uthuli, nokudlidliza. Kulezi zindawo, ukwethembeka nokuqina kubaluleke kakhulu kunokudluliswa okukhulu kwedatha. I-Industrial Ethernet yakhelwe lezi zimo. Izintambo nezixhumi ze-Industrial Ethernet (isb., izixhumi ze-M12) zivikelwe ukumelana ne-EMI nothuli, futhi amadivayisi e-Industrial Ethernet ayakuvunyelwa ukusebenza ezingeni lokushisa elidlulele. I-USB3.0, ngakolunye uhlangothi, isebenzisa izixhumi zokudla komphakathi (isb., Uhlobo-A, Uhlobo-C) ezingakhelwanga izindawo ezinzima—zilungele ukulimala ngokudlidliza futhi zingahlupheka ngenxa yokwehla kwesiginali ngenxa ye-EMI.

Noma ngabe kukhona okungeziwe okungavikela, izintambo ze-USB3.0 zithambekele kakhulu ekulahlekelweni isignali ezimeni ezinzima, okuholela ekulahlekelweni kwamarekhodi noma ukwehluleka kohlelo. Umklamo oqinile we-Industrial Ethernet uqinisekisa ukusebenza okuzinzile ngisho nasezindaweni ezinzima kakhulu, okwenza kube ukukhetha okuncamelayo kwezicelo ezibalulekile lapho ukungasebenzi kubiza kakhulu.
6. Isimo 4: Izicelo Ezihambayo noma Ezisebenzisa Amandla Aphansi (isb., Amakharriji Okuhlola Ahambayo, Izinhlelo Ezisebenzisa Ibhethri)
Ezinye izicelo zezimboni zidinga amamojuli ekhamera ahambayo—njengamakharriji okuhlola ahambayo asetshenziselwa ukuhlola imishini ezindaweni ezikude zefekthri, noma izinhlelo ezisebenzisa ibhethri ukuhlola ensimini (isb., ukuqapha imibhobho). Kulezi zimo, ukusebenza kahle kwamandla, usayizi omncane, nokusebenziseka kalula kuyizinto ezibaluleke kakhulu.
I-USB3.0 iyona engcono kakhulu lapha. Izikhamera eziningi ze-USB3.0 zincane futhi zilula, okwenza kube lula ukuzihlanganisa nezinhlelo eziphathekayo. I-USB3.0 iphinde inikeze amandla ngqo kukhamera (kufika ku-4.5W), iqeda isidingo samandla ahlukene—okubalulekile kumadivayisi anikwa amandla ngebhethri. Umsebenzi wokuxhuma nokudlala uvumela abasebenzisi ukuthi baxhume ikhamera kwi-laptop noma ithebhulethi ngokushesha, ngaphandle kokucushwa okuyinkimbinkimbi kwenethiwekhi.
I-Industrial Ethernet, ngokuphambene, idinga ihadiwe eyengeziwe (ama-switch, ama-PoE injector) engeza ubukhulu nokusetshenziswa kwamandla—okwenza ingasebenzi ezinhlelweni eziphathekayo. Ngenkathi i-PoE inikeza amandla, isidingo sengqalasizinda yenethiwekhi sikhawulela ukuhamba.
7. Uhlaka Lwezinqumo: Indlela Yokukhetha Phakathi Kwe-Industrial Ethernet Ne-USB3.0
