Ziziphi iimfuno ezikhethekileyo zeentambo zeProfinethi?

I-Profinet yi-Ethernet-based based communication protocol protocol, esetyenziswa ngokubanzi kwiinkqubo zokulawula i-automation, i-Profinet cable iimfuno ezikhethekileyo zigxininise kakhulu kwiimpawu zomzimba, ukusebenza kombane, ukuguquguquka kokusingqongileyo kunye neemfuno zokufakela. Eli nqaku liza kugxininisa kwi-cable ye-Profinet ukuhlalutya ngokubanzi.

I. Iimpawu zoMzimba

1, uhlobo lwentambo

IShielded Twisted Pair (STP/FTP): IShielded Twisted Pair iyacetyiswa ukunciphisa ukuphazamiseka kwe-electromagnetic interference (EMI) kunye ne-crosstalk. Izibini ezijijekileyo ezikhuselweyo zinokuthintela ngokufanelekileyo ukuphazamiseka kwe-electromagnetic yangaphandle kunye nokuphucula uzinzo kunye nokuthembeka kokuhanjiswa komqondiso.

I-Twisted Twisted Pair (UTP): I-Twisted Twisted Pair ingasetyenziswa kwiindawo ezinokuphazamiseka okuncinci kwe-electromagnetic, kodwa ayikhuthazwa ukuba isetyenziswe kwiindawo zoshishino.

2, ubume bentambo

Izibini ezine zentambo ephothiweyo: Ikhebula le-Profinet lihlala liqukethe izibini ezine ze-twisted-pair cable, ibini nganye yeengcingo ezenziwe ngeengcingo ezimbini zokuhanjiswa kwedatha kunye nokunikezelwa kwamandla (ukuba kuyimfuneko).

I-Wire Diameter: I-wire diameters ngokuqhelekileyo i-22 AWG, i-24 AWG, okanye i-26 AWG, kuxhomekeke kumgama wothumelo kunye neemfuno zamandla omqondiso. I-24 AWG ilungele imigama emide yothumelo, kwaye i-26 AWG ilungele imigama emifutshane.

3, Isidibanisi

Isixhumi se-RJ45: Iintambo ze-Profinet zisebenzisa izixhumi eziqhelekileyo ze-RJ45 ukuqinisekisa ukuhambelana nezixhobo zeProfinet.

I-Locking Mechanism: Izixhumi ze-RJ45 ezineendlela zokutshixa zinconywa kwiindawo zoshishino ukukhusela ukudibanisa okukhululekile kunye nokuqinisekisa ukuthembeka koqhagamshelwano.

Okwesibini, ukuguquguquka kokusingqongileyo

1, Uluhlu lobushushu

Uyilo olubanzi lobushushu: Intambo yenzuzo kufuneka ikwazi ukusebenza ngokufanelekileyo kuluhlu olubanzi lobushushu, ngokuqhelekileyo lufuneka ukuxhasa -40 ° C ukuya kuma-70 ° C.

2, inqanaba lokhuseleko

Umgangatho wokhuseleko oluphezulu: Khetha iintambo ezinomgangatho wokhuseleko ophezulu (umz. IP67) ukuthintela ukungena kothuli kunye nomphunga wamanzi kwindawo yemizi-mveliso erhabaxa.

3, Ukungcangcazela kunye nokumelana nokothuka

Amandla omatshini: Iintambo zenzuzo kufuneka zibe nokungcangcazela okulungileyo kunye nokumelana nokothuka, zilungele ukungcangcazela kunye nokusingqongileyo.

4, ukuxhathisa imichiza

I-oyile, i-asidi kunye nokumelana ne-alkali: Khetha iintambo ezinokumelana neekhemikhali ezifana ne-oyile, i-asidi kunye nokumelana ne-alkali ukuziqhelanisa neendawo ezahlukeneyo zemizi-mveliso.

III. IiMfuno zoFakelo

1, Indlela yocingo

Kuthintele ukuphazamiseka okunamandla kombane: kwi-wiring kufuneka uzame ukunqanda ukubekelwa ngokunxuseneyo kunye neentambo zombane ezinombane ophezulu, iimotor kunye nezinye izixhobo zombane ezomeleleyo ukunciphisa ukuphazamiseka kwe-electromagnetic.

Uyilo olunengqiqo: Ukucwangciswa okunengqiqo kwendlela yocingo, ukuphepha ukugoba ngokugqithiseleyo okanye uxinzelelo kwintambo, ukuqinisekisa ukunyaniseka komzimba wekhebula.

2, Ukulungisa indlela

Isibiyeli esisisigxina: Sebenzisa i-bracket echanekileyo efanelekileyo kunye nesigxina ukuqinisekisa ukuba intambo igxininiswe ngokuqinileyo ukukhusela ukungcangcazela okanye ukunyakaza okubangelwa ukudibanisa okuxekethileyo.

Ishaneli yocingo kunye nombhobho: Kwiindawo ezinzima, kucetyiswa ukuba kusetyenziswe ishaneli yocingo okanye umbhobho wokukhusela ikhebula ukukhusela umonakalo womatshini kunye nefuthe lokusingqongileyo.

IV. Izatifikethi kunye nemigangatho

1.Imigangatho yokuthotyelwa

I-IEC 61158: Iintambo zenzuzo ziya kuhambelana nemigangatho ye-International Electrotechnical Commission (IEC), efana ne-IEC 61158.

Imodeli ye-ISO/OSI: Iintambo zenzuzo kufuneka zihambelane nomgangatho womzimba kunye nemigangatho yomaleko wedatha yemodeli ye-ISO/OSI.

V. Indlela yokukhetha

1, Uvavanyo lweemfuno zesicelo

Umgama wothumelo: Ngokwesicelo sokwenene somgama wothumelo ukukhetha uhlobo olufanelekileyo lwentambo. Ukuhanjiswa komgama omfutshane kunokukhetha i-24 AWG cable, ukuhanjiswa komgama omde kucetyiswa ukuba ukhethe i-22 AWG cable.

Iimeko zokusingqongileyo: Khetha intambo efanelekileyo ngokweqondo lobushushu, ukufuma, ukungcangcazela kunye nezinye izinto ezisingqongileyo zofakelo. Umzekelo, khetha intambo yokumelana nobushushu obuphezulu kwindawo yobushushu obuphezulu kunye nentambo engenamanzi yendawo efumileyo.

2, khetha uhlobo oluchanekileyo lwentambo

Intambo ejijekileyo ekhuselweyo: Intambo ejijekileyo ekhuselweyo iyacetyiswa ukuba isetyenziswe kwiindawo ezininzi zemizi-mveliso ukunciphisa ukuphazamiseka kwe-electromagnetic kunye ne-crosstalk.

Intambo engakhuselekanga ephothiweyo: kuphela kwimekobume yokuphazamiseka kwe-electromagnetic kuncinci ukusebenzisa intambo engakhuselekanga ephothiweyo.

3, qwalasela ukuguquguquka kokusingqongileyo

Uluhlu lobushushu, inqanaba lokukhusela, ukungcangcazela kunye nokuxhathisa ukothuka, ukuxhathisa imichiza: khetha iintambo ezinokusebenza ngokuzinzileyo kwindawo yesicelo sangempela.
