Zithini iimfuno ezizodwa kwiintambo zeprofayini?

Iprofayile yePrografitha ye-Ethernet-isekwe kwiNkqubo yokuLawulwa kweMizi-mveliso ye-Elernet, isetyenziswe ngokubanzi kwiinkqubo zokulawula ezenzekelayo, iimfuno ze-Plarnet ze-Plarby zentambo zijolise ikakhulu kwiimpawu zomzimba, ukusebenza kombane, ukulungelelaniswa kokusingqongileyo kunye neemfuno zokufaka. Eli nqaku liza kugxila kwintambo yeProfInit yohlalutyo oluneenkcukacha.

I. Iimpawu zomzimba

1, Uhlobo lwentambo

Isibini esijijekileyo (STP / FTP): I-FTP ye-FTED i-witted i-witted i-witch iyacetyiswa ukunciphisa uphazamiseko lwe-electromagnetic (i-EMI) kunye ne-crostalk. Isibini esijijekileyo esijijekileyo sinokuthintela ngokufanelekileyo ukuphazamiseka ngaphandle kwe-electromagnetic kwaye siphucule uzinzo kunye nokuthembeka kosulelo lomqondiso.

Isibini esijijekileyo (i-UTP): Isibini esingafunekiyo sinokusetyenziswa kwiindawo zokuphazamiseka okungaphantsi kwe-elektromagnetic, kodwa akucetyiswa ukuba isetyenziswe kwiindawo ezikumashishini.

I-2, I-Cable Dation

Izibini ezine zentambo-bhabha-jikelele ye-witcht: Intambo yeProfInit ihlala inamabini amane e-bible ejijekileyo, isibini ngasinye sengcinezelo esenziwe ngeengcingo ezimbini zokuhambisa idatha kunye nokunikezelwa kwamandla (ukuba kukho imfuneko).

I-Wire Seamereter: Iidayimitha zeWire zihlala ze-22 AWG, i-24 AWG, okanye i-26 AWG, kuxhomekeke kumgama ohambisayo kunye neemfuno zomqondiso. I-24 AWG ilungele ukutshintshela okude, kwaye i-26 AWG ilungele umgama omfutshane.

I-3, isinxibelelanisi

I-RJ45 isiQinisekiso: Iintambo zeProfInit Sebenzisa iziqhoboshi zeRJ45 zeRJ45 ukuqinisekisa ukuhambelana nezixhobo zeprofati.

Indlela yokutshixa: i-RJ45 yeziqhobos ezinendlela yokutshixa iyacetyiswa kwiindawo ezizizo zonxibelelwano ukuthintela unxibelelwano oluzimeleyo kwaye uqiniseke ukuthembeka konxibelelwano.

Okwesibini, ukubekwa kwendalo esingqongileyo

1, Uluhlu lobushushu

Uyilo lwamaqondo obushushu: Intambo yeProftinet kufuneka ikwazi ukusebenza ngokufanelekileyo kuluhlu lobushushu olubanzi, idla ngokufuneka ixhasa -40 ° C ukuya kwi-70 ° C.

I-2, inqanaba loKhuselo

Inqanaba lokukhuselwa: Khetha iintambo ngenqanaba lokhuseleko oluphezulu (umzekelo, i-IP67) ukuthintela ukungena kothuli kunye nomphunga wamanzi ngenxa yendawo enobungozi kwezomthetho.

I-3, i-vibration kunye nokunganyangeki kokothusayo

Amandla oomatshini: Iintambo zeprofayini kufuneka zibe ne-vibration elungileyo kunye nokunganyangeki kothusayo, kufanelekile ukuba kubekho indawo yokuhamba kunye nokothusayo.

4, Ukuxhathisa kweekhemikhali

Ioyile, I-Acid kunye neAlokali Ukunganyangeki: Khetha ii-canss zokungavisisani kwemichiza ezinjengeoyile, acid no-Alid noAlkali ukungakwazi ukuziqhelanisa neendawo ezahlukeneyo zeshishini.

III. Iimfuno zokufaka

1, indlela ye-wiring

Kuphephe ukuphazamiseka kombane okuqinileyo: kwi-wiring kufuneka uzame ukuphepha ukufana kwamandla e-Vightage, iMotors kunye nezinye izixhobo zombane ezomeleleyo zokunciphisa uphazamiso lwe-electromagnetic.

Ubume obufanelekileyo: Ukucwangciswa okufanelekileyo kwendlela ye-Wiring, ukuthintela ukugoba okugqithisileyo okanye uxinzelelo kwintambo, ukuqinisekisa ingqibelelo yentambo.

2, Indlela yokulungisa

I-bracket emiselweyo: Sebenzisa i-bracket efanelekileyo kunye ne-fittere ukuqinisekisa ukuba intambo ilungiswa ukuthintela ukunxibelelana okanye intshukumo ebangelwa lunxibelelwano olukhulu.

Itshaneli yombhobho kunye nombhobho: kwiindawo ezintsonkothileyo, kuyacetyiswa ukuba basebenzise itshaneli yewire okanye umbhobho wokukhusela intambo ukuthintela ukonakala koomatshini kunye nefuthe lokusingqongileyo.

Iv. Isiqinisekiso kunye nemigangatho

1, imigangatho yokuthobela

IEC 61158: Iintambo zeProftiet ziya kuthobela imigangatho yeKhomishini ye-elektrotechnical yehlabathi (iec), njengeec 61158.

Imodeli ye-ISO / OSI: Iintambo zeProfInit kufuneka zihambelane nongqimba lomzimba kunye nedatha yedatha ye-Iso / yemodeli ye-OSI.

V. Indlela yokhetho

1, Uvavanyo lweemfuno zesicelo

Umgama wokuhambisa: Ngokwesi sicelo soMgama odluliselwa ukukhetha uhlobo olufanelekileyo lwentambo. Ukudluliselwa komgama omfutshane unokukhetha intambo ye-24 AWG, ugqithiso lomgama omde lucetyiswa ukukhetha i-22 AWG MOWG.

IIMBALI ZOKUGQIBELA Umzekelo, khetha intambo yobushushu obunganyangekiyo kwimo yendawo yobushushu ephezulu kunye nentambo yamanzi yendalo engcolileyo.

2, Khetha uhlobo olufanelekileyo lwentambo

I-Cable ejijekileyo ejijekileyo: I-Cable-intambo ye-witch ejijekileyo iyacetyiswa ukuba isetyenziswe kwiindawo ezininzi zemizi-mveliso ukuze zinciphise ukuphazamiseka kwe-electromagnetic kunye ne-crostalk.

I-cable engafunekiyo ejijekileyo: kuphela kwindalo yokuphazamiseka kwe-electromagnetic incinci ukusebenzisa i-cable-hard-ters-wible.

3, qwalasela ukuziqhelanisa okusingqongileyo

Uluhlu lobushushu, inqanaba lokukhusela, ukuntywila kunye nokuchasana nokothusa, ukuxhathisa imichiza: Khetha iintambo ezinokusebenza ngokokwenyani kwimeko yesicelo.
