Ndezvipi zvinodiwa zvakakosha zvetambo dzeProfinet?

Profinet inzira yekukurukurirana yeindasitiri yakavakirwa paEthernet, inoshandiswa zvakanyanya muhurongwa hwekudzora otomatiki, zvinodiwa zvakakosha zveProfinet cable zvinonyanya kutarisa hunhu hwemuviri, mashandiro emagetsi, kuchinjika kwezvakatipoteredza uye zvinodiwa zvekuisa. Chinyorwa chino chichatarisa pane tambo yeProfinet kuti iongororwe zvakadzama.

I. Hunhu hwemuviri

1, rudzi rwetambo

Shielded Twisted Pair (STP/FTP): Shielded Twisted Pair inokurudzirwa kuderedza electromagnetic interference (EMI) uye crosstalk. Shielded twisted pair inogona kudzivirira zvinobudirira electromagnetic interference yekunze uye kugadzirisa kugadzikana uye kuvimbika kwekutumira masaini.

Unshielded Twisted Pair (UTP): Unshielded Twisted Pair inogona kushandiswa munzvimbo dzisina kukanganiswa kwemagetsi zvakanyanya, asi haikurudzirwi kushandiswa munzvimbo dzemaindasitiri.

2, chimiro chetambo

Mapaya mana etambo dzakamonyoroka: Tambo yeProfinet inowanzova nemapaya mana etambo dzakamonyoroka, paya imwe neimwe yetambo inoumbwa netambo mbiri dzekutumira data nemagetsi (kana zvichidikanwa).

Dhayamita yewaya: Dhayamita yewaya inowanzova 22 AWG, 24 AWG, kana 26 AWG, zvichienderana nedaro rekutumira uye simba rechiratidzo. 24 AWG yakakodzera daro refu rekutumira, uye 26 AWG yakakodzera daro pfupi.

3, Chinobatanidza

Chinobatanidza cheRJ45: Tambo dzeProfinet dzinoshandisa zvibatanidza zveRJ45 zvakajairwa kuti dzive nechokwadi chekuti zvinoenderana nemidziyo yeProfinet.

Nzira Yokukiya: Zvinobatanidza zveRJ45 zvine nzira yekukiya zvinokurudzirwa munzvimbo dzemaindasitiri kudzivirira kubatana kusina kusimba uye kuve nechokwadi chekuti kubatana kwacho kwakavimbika.

Chechipiri, kuchinjika kwezvakatipoteredza

1, Tembiricha siyana

Dhizaini yekupisa kwakafara: Tambo yeProfinet inofanira kukwanisa kushanda zvakanaka munzvimbo dzakasiyana siyana dzekupisa, kazhinji inodiwa kuti itsigire nzvimbo dzekupisa -40 ° C kusvika 70 ° C.

2, Dziviriro

Dziviriro yepamusoro: Sarudza tambo dzine dziviriro yepamusoro (semuenzaniso IP67) kudzivirira kupinda kweguruva nemhepo inofefetera munzvimbo dzakaoma dzemaindasitiri.

3, Kudedera uye kuramba kuvhunduka

Simba remuchina: Tambo dzeProfinet dzinofanira kunge dziine vibration yakanaka uye dzisingagoni kuvhunduka, dzakakodzera kuvhunduka uye nzvimbo yekuvhunduka.

4, kuramba makemikari

Kudzivirira mafuta, asidhi uye alkali: Sarudza tambo dzine makemikari anodzivirira senge mafuta, asidhi uye alkali kuti dzienderane nemamiriro akasiyana emaindasitiri.

III. Zvinodiwa pakuisa

1, nzira yekubatanidza waya

Dzivisa kukanganiswa kwakasimba kwemagetsi: muwaya dzinofanira kuedza kudzivirira kuiswa pamwe chete netambo dzemagetsi dzine simba guru, mamota nezvimwe zvishandiso zvemagetsi zvakasimba kuderedza kukanganiswa kwemagetsi.

Kurongeka kwakanaka: Kuronga nzira yekubatanidza waya zvine musoro, kudzivirira kukotama zvakanyanya kana kumanikidzwa pawaya, kuve nechokwadi chekuti waya yacho yakasimba.

2, Nzira yekugadzirisa

Chinosungirirwa: Shandisa chinobatanidza chakakodzera uye chinosungirirwa kuti uve nechokwadi chekuti tambo yacho yakanyatsoiswa kudzivirira kudedera kana kufamba kunokonzerwa nekubatana kwakasununguka.

Nzira yewaya nepaipi: Munzvimbo dzakaoma, zvinokurudzirwa kushandisa nzira yewaya kana paipi kudzivirira tambo kudzivirira kukuvara kwemakanika uye kukanganiswa kwezvakatipoteredza.

IV. Chitupa nemiyero

1, mitemo yekutevedzera mitemo

IEC 61158: Tambo dzeProfinet dzinofanira kutevedzera mitemo yeInternational Electrotechnical Commission (IEC), yakaita seIEC 61158.

Muenzaniso weISO/OSI: Tambo dzeProfinet dzinofanira kutevedzera mitemo yeISO/OSI model ine layer chaiyo uye data link.

V. Nzira yekusarudza

1. Kuongorora zvinodiwa pakushandisa chikumbiro

Kureba kwekutumira: Zvichienderana nekushandiswa chaiko kwedaro rekutumira, sarudza rudzi rwakakodzera rwetambo. Kureba kwekutumira kunogona kusarudza tambo ye24 AWG, kureba kwekutumira kunokurudzirwa kusarudza tambo ye22 AWG.

Mamiriro ekunze: Sarudza tambo yakakodzera zvichienderana nekupisa, hunyoro, kudedera nezvimwe zvinhu zvenzvimbo yekuisa. Semuenzaniso, sarudza tambo inodzivirira kupisa kwakanyanya panzvimbo yekupisa kwakanyanya uye tambo isingapindi mvura panzvimbo ine hunyoro.

2, sarudza mhando chaiyo yetambo

Waya yakamoneredzwa: Waya yakamoneredzwa yakamoneredzwa inokurudzirwa kushandiswa munzvimbo zhinji dzemaindasitiri kuderedza kukanganiswa kwemagetsi uye kutaura kwemagetsi.

Waya yakamonyoroka isina chidzitiro: tambo diki chete kana paine kupindirana kwemagetsi inoshandiswa netambo isina chidzitiro yakamonyoroka isina chidzitiro.

3, funga nezvekuchinja-chinja kwezvakatipoteredza

Kureba kwekupisa, mwero wekudzivirira, kudedera uye kuramba kuvhunduka, kuramba makemikari: sarudza tambo dzinogona kushanda zvakadzikama munzvimbo chaiyo yekushandisa.
