Kodi zofunika zapadera za zingwe za Profine ndi chiyani?

Profinet ndi njira yolumikizirana yamafakitale ya Efaneti, yomwe imagwiritsidwa ntchito kwambiri pamakina owongolera makina, chingwe cha Profinet chofunikira kwambiri chimayang'ana kwambiri mawonekedwe akuthupi, magwiridwe antchito amagetsi, kusinthika kwa chilengedwe komanso zofunikira pakuyika. Nkhaniyi idzayang'ana pa chingwe cha Profinet kuti tifufuze mwatsatanetsatane.

I. Makhalidwe Athupi

1, mtundu wa chingwe

Shielded Twisted Pair (STP/FTP): Shielded Twisted Pair tikulimbikitsidwa kuti muchepetse kusokoneza kwa electromagnetic (EMI) ndi crosstalk. Ma awiri opotoka otetezedwa amatha kuteteza kusokoneza kwa ma elekitiroma akunja ndikuwongolera kukhazikika ndi kudalirika kwa kutumizira ma siginecha.

Unshielded Twisted Pair (UTP): Unshielded Twisted Pair atha kugwiritsidwa ntchito m'malo osasokoneza ma elekitiromu pang'ono, koma sizovomerezeka kuti zigwiritsidwe ntchito m'mafakitale.

2, kapangidwe ka chingwe

Mawiri awiri a chingwe chopotoka: Chingwe cha Profinet nthawi zambiri chimakhala ndi mawiri anayi a chingwe chopotoka, mawaya aliwonse opangidwa ndi mawaya awiri otumizira deta ndi magetsi (ngati kuli kofunikira).

Waya Diameter: Ma diameter a waya amakhala 22 AWG, 24 AWG, kapena 26 AWG, kutengera mtunda wotumizira komanso zofunikira zamphamvu zama siginecha. 24 AWG ndiyoyenera mtunda wautali wotumizira, ndipo 26 AWG ndiyoyenera mtunda waufupi.

3. Cholumikizira

Cholumikizira cha RJ45: Zingwe za Profinet zimagwiritsa ntchito zolumikizira zokhazikika za RJ45 kuti zitsimikizire kuti zimagwirizana ndi zida za Profinet.

Njira Yotsekera: Zolumikizira za RJ45 zokhala ndi makina otsekera zimalimbikitsidwa kuti zizichitika m'mafakitale kuti apewe kulumikizana kotayirira ndikuwonetsetsa kudalirika kwa kulumikizana.

Chachiwiri, kusinthasintha kwa chilengedwe

1, Kutentha osiyanasiyana

Mapangidwe a kutentha kwakukulu: Chingwe cha Profinet chiyenera kugwira ntchito bwino pa kutentha kwakukulu, kawirikawiri kumafunika kuthandizira -40 ° C mpaka 70 ° C kutentha.

2, chitetezo mlingo

Mulingo wapamwamba wachitetezo: Sankhani zingwe zotetezedwa kwambiri (mwachitsanzo IP67) kuti fumbi ndi nthunzi wamadzi zisalowe m'malo ovuta a mafakitale.

3, Kugwedezeka ndi kukana kugwedezeka

Mphamvu zamakina: Zingwe za Profinet ziyenera kukhala ndi kugwedezeka kwabwino komanso kukana kugwedezeka, zoyenera kugwedezeka komanso malo ogwedezeka.

4, kukana mankhwala

Mafuta, asidi ndi kukana kwa alkali: Sankhani zingwe zolimbana ndi mankhwala monga mafuta, asidi ndi kukana kwa alkali kuti zigwirizane ndi malo osiyanasiyana ogulitsa.

III. Zofunikira pakuyika

1, Njira yolumikizira

Pewani kusokoneza kwamphamvu kwamagetsi: mu mawaya yesetsani kupewa kuyala kofanana ndi zingwe zamagetsi zamphamvu kwambiri, ma mota ndi zida zina zamphamvu zamagetsi kuti muchepetse kusokoneza kwa ma elekitiroma.

Kukonzekera koyenera: Kukonzekera koyenera kwa njira yopangira waya, kupewa kupindika kwambiri kapena kupanikizika pa chingwe, kuonetsetsa kuti chingwecho chikuyenda bwino.

2, Kukonza njira

Bracket yokhazikika: Gwiritsani ntchito bulaketi yoyenera yokhazikika ndikuyikapo kuti muwonetsetse kuti chingwecho chili chokhazikika kuti chiteteze kugwedezeka kapena kusuntha komwe kumachitika chifukwa cholumikizana momasuka.

Waya njira ndi chitoliro: M'malo ovuta, tikulimbikitsidwa kugwiritsa ntchito njira ya waya kapena chitoliro poteteza chingwe kuteteza kuwonongeka kwa makina ndi kuwononga chilengedwe.

IV. Certification ndi miyezo

1, Kutsata miyezo

IEC 61158: Zingwe zopindulitsa ziyenera kutsatira miyezo ya International Electrotechnical Commission (IEC), monga IEC 61158.

Mtundu wa ISO/OSI: Zingwe za phindu zikuyenera kutsatizana ndi makulidwe amtundu wamtundu wa ISO/OSI.

V. Njira yosankha

1, Kuunika kwa zofunikira za ntchito

Mtunda wotumizira: Malinga ndi kugwiritsa ntchito kwenikweni kwa mtunda wotumizira kusankha mtundu woyenera wa chingwe. Kutumiza kwakutali kumatha kusankha chingwe cha 24 AWG, kufalitsa mtunda wautali kumalimbikitsidwa kusankha chingwe cha 22 AWG.

Mikhalidwe ya chilengedwe: Sankhani chingwe choyenera malinga ndi kutentha, chinyezi, kugwedezeka ndi zinthu zina za chilengedwe. Mwachitsanzo, sankhani chingwe chosasunthika kutentha kwambiri kwa chilengedwe cha kutentha kwambiri ndi chingwe chopanda madzi cha chilengedwe cha chinyezi.

2, sankhani chingwe choyenera

Chingwe chopotoka: Chingwe chotchinga chotchingidwa chimalimbikitsidwa kuti chizigwiritsidwa ntchito m'malo ambiri ogulitsa kuti muchepetse kusokoneza kwa ma elekitiroma ndi crosstalk.

Chingwe chopotoka chopanda chitetezo: m'malo omwe kusokoneza kwa ma elekitiroma ndi kochepa kuti mugwiritse ntchito chingwe chopindika chosatetezedwa.

3, lingalirani kusinthasintha kwa chilengedwe

Kutentha kosiyanasiyana, mulingo wachitetezo, kugwedezeka ndi kukana kugwedezeka, kukana kwamankhwala: sankhani zingwe zomwe zimatha kugwira ntchito mokhazikika pamalo omwe akugwiritsira ntchito.
