Ese insinga ya RS485 ni imwe n'insinga ya Ethernet?
Igisubizo cyihuse: Oya, umugozi wa RS485 ntabwo ari kimwe n'umugozi wa Ethernet.
Injeniyeri nyinshi n'inzobere mu gutanga amasoko bakunze kwitiranya aya mahame yombi y'itumanaho. Nubwo yombi yohereza amakuru mu nganda, akora ku mahame atandukanye cyane, agakoresha insinga zitandukanye, kandi agatanga serivisi zitandukanye cyane.
RS485 (ku mugaragaro TIA/EIA-485) ni igipimo ngenderwaho cy'urwego rw'umubiri ku itumanaho ryihuse, rigaragaza gusa imiterere y'amashanyarazi y'ibikoresho byohereza amakuru n'ibyakira. Ethernet (IEEE 802.3) ni porotoli yuzuye y'itumanaho igena urwego rw'umubiri n'urwego rw'amakuru.
Gusobanukirwa izi tandukaniro ni ingenzi cyane mu kugaragaza insinga ikwiye ya sisitemu yawe y’imikorere y’inganda, umuyoboro wo kugenzura ibikorwa, cyangwa ishyirwa mu bikorwa rya IIoT.
1Itandukaniro ry'ibanze: Icyiciro cy'umubiri ugereranije na Stack yuzuye ya Porotoli
Mbere yo gusuzuma ibipimo bya cable, ni ngombwa gusobanukirwa iri tandukaniro ry'ibanze:
| Uburyo bwo kugereranya | RS485 | Ethaneti |
|---|---|---|
| Ibisobanuro | Ibipimo ngenderwaho by'urwego rw'umubiri gusa (imiterere y'amashanyarazi) | Urupapuro rwuzuye rwa protocole (ibipimo by'ikoranabuhanga + amakuru) |

(Kugereranya ibice bitandukanye: Insinga ya RS485 120Ω vs. Insinga ya Ethernet Cat6a 100ohm) 3Ibisabwa mu kurinda: Ikintu cy'ingenzi gitandukanya
RS485 na Ethernet byombi bigira uruhare mu kurinda, ariko ibisabwa biratandukanye cyane bitewe n'aho porogaramu ikorerwa.
Imbonerahamwe ya 2: Igereranya ry'uburinzi ku bidukikije by'inganda
| Ubwoko bw'uburinzi | Porogaramu ya RS485 | Porogaramu ya Ethernet |
|---|---|---|
| Ibirindiro Bidakingiye (UTP) | Bikwiriye ahantu hagufi mu bice by'amashanyarazi gusa | Cat5e/Cat6 UTP ku bidukikije by'ibiro |

Urugero rw'insinga za RS485 (Belden 9841NH):
Dukurikije urupapuro rw'amakuru yerekeye insinga isanzwe ya RS485:
- Umuyobozi: AWG24 (7×AWG32) umuringa wo mu gikombe
- Ubwishingizi bw'umuriro: Polyethylene (PE)
- Gukingira: Beldfoil® (aluminium/polyester) + umugozi w'umuringa wo mu gikombe (90% by'ubuso)
- Ikiziriko: FRNC (Idakonjesha Umuriro), Imirasire y'Umucyo ihamye
- Ingano y'inyuma: mm 5.90
Ingingo y'ingenzi: Kuri RS485 mu nganda, ipfundo ry'imigozi ritwikiriwe (STP) rirasabwa cyane bitewe n'urusaku rukabije rw'aho uruganda rukorera.
4Intera ugereranije n'umuvuduko: Ihindagurika ry'Ubuhanga mu by'Ubwubatsi
RS485 ikurikira isano inyuranye hagati y'uburebure bw'insinga n'umuvuduko w'amakuru. Uko insinga iba ndende, niko umuvuduko ntarengwa wizewe ugenda ugabanuka.
Imbonerahamwe ya 3: Intera ya RS485 ugereranyije n'igipimo cy'amakuru
| Uburebure bw'insinga | Igipimo ntarengwa cy'amakuru | Uburyo busanzwe bwo gukoresha |

| Metero 300 (futi 984) | ~1-5 Mbps | Igorofa ry'uruganda, amatsinda y'ibikoresho |
| Metero 600 (1,968 ft) | ~500 kbps | Ahantu hanini h'inganda |
| Metero 1.200 (futi 4.000) | ≤100 kbps | Ibikoresho byo kugenzura imiyoboro bya kure, kugenzura imiyoboro |
(Intera ya RS485 ugereranyije n'umuvuduko w'amakuru ugaragaza isano inyuranye) Imbogamizi za Ethernet: Ethernet ifite aho igarukira kuri Metero 100 kuri buri gice hatitawe ku muvuduko (ku bijyanye no gushyiramo insinga z'umuringa). Uretse ibi, hakenewe repeaters cyangwa fiber optique.
Kuki hari itandukaniro? RS485 ikoresha ibimenyetso bitandukanya bikomeza ubuziranenge mu ntera ndende, ariko ubushobozi bwo gukoresha no kugabanya ibimenyetso ku nsinga bigabanya umuvuduko ntarengwa. Ibimenyetso bya Ethernet bigabanya umuvuduko mwinshi mu ntera.
