Yiziphi izidingo ezikhethekile zezintambo ze-Profinet?

I-Profinet iyiphrothokholi yokuxhumana yezimboni esekwe ku-Ethernet, esetshenziswa kabanzi ezinhlelweni zokulawula okuzenzakalelayo, izidingo ezikhethekile zekhebula le-Profinet zigxile kakhulu ezicini zomzimba, ukusebenza kukagesi, ukuguquguquka kwemvelo kanye nezidingo zokufakwa. Lesi sihloko sizogxila kukhebula le-Profinet ukuze kuhlaziywe kabanzi.

I. Izici Zomzimba

1, uhlobo lwekhebula

I-Shielded Twisted Pair (STP/FTP): I-Shielded Twisted Pair iyanconywa ukuze kuncishiswe ukuphazamiseka kwe-electromagnetic (EMI) kanye ne-crosstalk. Ukupheya okusontekile okuvikelekile kungavimbela ngempumelelo ukuphazamiseka kozibuthe kwangaphandle futhi kuthuthukise ukuzinza nokuthembeka kokudluliswa kwesignali.

I-Unshielded Twisted Pair (I-UTP): Ibhangqa Elisontekile Elingavikelekile lingasetshenziswa ezindaweni ezinokuphazamiseka okuncane kozibuthe, kodwa akunconyelwe ukusetshenziswa ezindaweni zezimboni.

2, isakhiwo sekhebula

Amapheya amane ekhebula elisontekile: Ikhebula le-Profinet ngokuvamile liqukethe amapheya amane ekhebula elisontekile, ipheya ngalinye lezintambo elakhiwe izintambo ezimbili zokudlulisa idatha namandla (uma kunesidingo).

I-Wire Diameter: Amadayamitha ocingo ngokuvamile angu-22 AWG, 24 AWG, noma 26 AWG, kuye ngebanga lokudlulisela kanye nezidingo zamandla esignali. I-24 AWG ifanele amabanga amade wokudlulisela, futhi i-26 AWG ifanele amabanga amafushane.

3, Isixhumi

Isixhumi se-RJ45: Izintambo ze-Profinet zisebenzisa izixhumi ezijwayelekile ze-RJ45 ukuze kuqinisekiswe ukuhambisana namadivayisi we-Profinet.

I-Locking Mechanism: Izixhumi ze-RJ45 ezinomshini wokukhiya zinconywa ezindaweni zezimboni ukuvimbela ukuxhuma okuxekethile nokuqinisekisa ukwethembeka koxhumano.

Okwesibili, ukuguquguquka kwemvelo

1. Izinga lokushisa

Idizayini yokushisa ebanzi: Ikhebula lenzuzo kufanele likwazi ukusebenza kahle ebangeni lokushisa elibanzi, ngokuvamile elidingekayo ukuze lisekele izinga lokushisa elingu-40 ° C kuya ku-70 ° C.

2. Izinga lokuvikela

Izinga eliphezulu lokuvikela: Khetha izintambo ezinezinga eliphezulu lokuvikela (isb. IP67) ukuze uvimbele ukungena kothuli nomhwamuko wamanzi ezindaweni zezimboni ezinonya.

3, Ukudlidliza kanye nokumelana nokushaqeka

Amandla omshini: Izintambo zenzuzo kufanele zibe nokudlidliza okuhle nokumelana nokushaqeka, ezifanele ukudlidliza kanye nemvelo yokushaqeka.

4, ukumelana namakhemikhali

Ukumelana nowoyela, i-asidi ne-alkali: Khetha izintambo ezinokumelana namakhemikhali njengokumelana nowoyela, i-asidi ne-alkali ukuze uzivumelanise nezimo ezihlukene zezimboni.

III. Izidingo zokufaka

1. Indlela yezintambo

Gwema ukuphazamiseka okunamandla kagesi: ezintanjeni kufanele zizame ukugwema ukubeka okuhambisanayo nezintambo zamandla kagesi aphezulu, izinjini nezinye izinto ezisebenza ngogesi ezinamandla ukuze kuncishiswe ukuphazamiseka kukazibuthe.

Isakhiwo esinengqondo: Ukuhlela okunengqondo kwendlela yezintambo, ukugwema ukugoba ngokweqile noma ukucindezela ikhebula, ukuqinisekisa ubuqotho bomzimba bekhebula.

2. Indlela yokulungisa

Abakaki abagxilile: Sebenzisa ubakaki abamisiwe abafanelekile kanye nesakhiwo sokuqinisekisa ukuthi ikhebula ligxiliswe ngokuqinile ukuze kuvinjwe ukudlidliza noma ukunyakaza okubangelwa ukuxega kokuxhuma.

Ishaneli yocingo nepayipi: Ezimweni eziyinkimbinkimbi, kunconywa ukusebenzisa ishaneli yocingo noma ipayipi ukuze kuvikelwe ikhebula ukuvimbela ukulimala komshini nomthelela emvelweni.

IV. Izitifiketi kanye namazinga

1, Izindinganiso zokuthobela

I-IEC 61158: Izintambo zenzuzo zizohambisana namazinga e-International Electrotechnical Commission (IEC), njenge-IEC 61158.

Imodeli ye-ISO/OSI: Amakhebuli enzuzo kufanele athobelane nesendlalelo esibonakalayo kanye namazinga wesendlalelo sedatha yemodeli ye-ISO/OSI.

V. Indlela yokukhetha

1, Ukuhlolwa kwezidingo zesicelo

Ibanga lokudlulisela: Ngokusho kokusetshenziswa kwangempela kwebanga lokudlulisela ukukhetha uhlobo olufanele lwekhebula. Ukudluliswa kwebanga elifushane kungakhetha ikhebula le-24 AWG, ukudluliswa kwebanga elide kunconywa ukukhetha ikhebula lama-22 AWG.

Izimo zemvelo: Khetha ikhebula elifanele ngokwezinga lokushisa, umswakama, ukudlidliza nezinye izici zendawo yokufaka. Isibonelo, khetha ikhebula elimelana nezinga lokushisa eliphezulu lendawo yokushisa okuphezulu nekhebula elingangeni manzi endaweni enomswakama.

2, khetha uhlobo olulungile lwekhebula

Ikhebula elisontekile elivikelekile: Ikhebula elisontekile elivikelekile liyanconywa ukuthi lisetshenziswe ezindaweni eziningi zezimboni ukuze kuncishiswe ukuphazamiseka kozibuthe kanye ne-crosstalk.

Ikhebula elisontekile elingavikelekile: endaweni kuphela lapho kuphazanyiswa kazibuthe kagesi kuncane ukuze usebenzise ikhebula elisontekile elingavikelekile.

3, cabangela ukuguquguquka kwemvelo

Ibanga lokushisa, izinga lokuvikela, ukudlidliza kanye nokumelana nokushaqeka, ukumelana namakhemikhali: khetha izintambo ezingasebenza ngokuzinza endaweni yangempela yohlelo lokusebenza.
