Yiziphi izidingo ezikhethekile zamakhebula e-Profinet?

I-Profinet iyiphrothokholi yokuxhumana kwezimboni esekelwe ku-Ethernet, esetshenziswa kabanzi ezinhlelweni zokulawula ezenzakalelayo, izidingo ezikhethekile zekhebula le-Profinet zigxile kakhulu ezicini zomzimba, ukusebenza kukagesi, ukuzivumelanisa nezimo kwemvelo kanye nezidingo zokufaka. Lesi sihloko sizogxila kukhebula le-Profinet ukuze kuhlaziywe ngokuningiliziwe.

I. Izici Zomzimba

1, uhlobo lwekhebula

I-Shielded Twisted Pair (STP/FTP): I-Shielded Twisted Pair iyanconywa ukunciphisa ukuphazamiseka kwe-electromagnetic (EMI) kanye nokuxoxa nge-crosstalk. I-Shielded twisted pair ingavimbela ngempumelelo ukuphazamiseka kwe-electromagnetic yangaphandle futhi ithuthukise ukuzinza nokuthembeka kokudluliswa kwesignali.

I-Unshielded Twisted Pair (UTP): I-Unshielded Twisted Pair ingasetshenziswa ezindaweni ezingenakho ukuphazamiseka okukhulu kwe-electromagnetic, kodwa ayikhuthazwa ukusetshenziswa ezindaweni zezimboni.

2, isakhiwo sekhebula

Ama-pair amane ekhebula elijijekile: Ikhebula le-Profinet livame ukuba nama-pair amane ekhebula elijijekile, i-pair ngayinye yezintambo yakhiwe izintambo ezimbili zokudlulisa idatha kanye nokunikezwa kwamandla (uma kudingeka).

Ububanzi Bentambo: Ububanzi bentambo buvame ukuba yi-22 AWG, 24 AWG, noma i-26 AWG, kuye ngebanga lokudlulisa kanye nezidingo zamandla esignali. I-24 AWG ifanelekela amabanga amade okudlulisa, kanti i-26 AWG ifanelekela amabanga amafushane.

3, Isixhumi

Isixhumi se-RJ45: Izintambo ze-Profinet zisebenzisa izixhumi ze-RJ45 ezijwayelekile ukuqinisekisa ukuhambisana namadivayisi e-Profinet.

Indlela Yokukhiya: Izixhumi ze-RJ45 ezinendlela yokukhiya ziyanconywa ezindaweni zezimboni ukuvimbela ukuxhumana okuxekethile nokuqinisekisa ukuthembeka kokuxhumana.

Okwesibili, ukuzivumelanisa nezimo kwemvelo

1, Izinga lokushisa ububanzi

Umklamo wokushisa obanzi: Ikhebula le-Profinet kufanele likwazi ukusebenza kahle ebangeni lokushisa elibanzi, ngokuvamile elidingekayo ukusekela izinga lokushisa elingu-40 ° C kuya ku-70 ° C.

2, Izinga Lokuvikela

Izinga lokuvikela eliphezulu: Khetha izintambo ezinezinga lokuvikela eliphezulu (isb. IP67) ukuvimbela ukungena kothuli nomhwamuko wamanzi ezindaweni zezimboni ezinzima.

3, ukumelana nokudlidliza nokushaqeka

Amandla okusebenza: Izintambo ze-Profinet kufanele zibe nokudlidliza okuhle kanye nokumelana nokushaqeka, ezifanele ukudlidliza kanye nendawo yokushaqeka.

4, ukumelana namakhemikhali

Ukumelana ne-oyela, i-asidi kanye ne-alkali: Khetha izintambo ezinokumelana namakhemikhali njengokumelana ne-oyela, i-asidi kanye ne-alkali ukuze uzivumelanise nezimo ezahlukene zezimboni.

III. Izidingo Zokufaka

1, indlela yokuxhumanisa

Gwema ukuphazamiseka okukhulu kukagesi: ezintanjeni kufanele uzame ukugwema ukufakwa kwezintambo zikagesi ezinamandla aphezulu, ama-motor kanye neminye imishini kagesi eqinile ukuze unciphise ukuphazamiseka kukagesi.

Ukuhlelwa okunengqondo: Ukuhlela okunengqondo kwendlela yokuxhuma izintambo, ukugwema ukugoba ngokweqile noma ukucindezela ikhebula, ukuqinisekisa ubuqotho obubonakalayo bekhebula.

2, Indlela yokulungisa

Ibhulakhethi Elungisiwe: Sebenzisa ibhulakhethi elungisiwe efanele kanye ne-fixture ukuqinisekisa ukuthi ikhebula liqinile ukuvimbela ukudlidliza noma ukunyakaza okubangelwa ukuxhumeka okuxegayo.

Isiteshi sezintambo kanye nepayipi: Ezindaweni eziyinkimbinkimbi, kunconywa ukusebenzisa isiteshi sezintambo noma ipayipi ukuvikela ikhebula ukuvimbela umonakalo wemishini kanye nomthelela emvelweni.

IV. Isitifiketi kanye namazinga

1, amazinga okuthobela imithetho

I-IEC 61158: Amakhebula e-Profinet kumele ahambisane nezindinganiso ze-International Electrotechnical Commission (IEC), njenge-IEC 61158.

Imodeli ye-ISO/OSI: Izintambo ze-Profinet kufanele zihambisane nezindinganiso zesendlalelo esingokoqobo kanye nesendlalelo sesixhumanisi sedatha semodeli ye-ISO/OSI.

V. Indlela yokukhetha

1. Ukuhlolwa kwezimfuneko zesicelo

Ibanga lokudlulisa: Ngokusebenzisa ibanga lokudlulisa, ukukhetha uhlobo lwekhebula olufanele. Ukudlulisa ibanga elifushane kungakhetha ikhebula le-24 AWG, ukudlulisa ibanga elide kunconywa ukuthi ukhethe ikhebula le-22 AWG.

Izimo zemvelo: Khetha ikhebula elifanele ngokuya ngezinga lokushisa, umswakama, ukudlidliza nezinye izici zendawo yokufaka. Isibonelo, khetha ikhebula elingamelani nokushisa okuphezulu endaweni enokushisa okuphezulu kanye nekhebula elingangeni manzi endaweni enomswakama.

2, khetha uhlobo olufanele lwekhebula

Ikhebula eligoqekile elivikelwe: Ikhebula eligoqekile elivikelwe linconywa ukuthi lisetshenziswe ezindaweni eziningi zezimboni ukunciphisa ukuphazamiseka kwe-electromagnetic kanye nokukhuluma ngokuphambene.

Ikhebula elijijekile elingavikelwe: kuphela endaweni lapho kukhona ukuphazamiseka kwe-electromagnetic, ikhebula elijijekile elingavikelwe lingavikelwe lincane.

3, cabanga ngokuzivumelanisa nezimo kwemvelo

Ububanzi bokushisa, izinga lokuvikelwa, ukudlidliza kanye nokumelana nokushaqeka, ukumelana namakhemikhali: khetha izintambo ezingasebenza ngokuzinzile endaweni yokusebenza yangempela.
