2024-12-05 10:41:08
Imbonerahamwe
Mw'isi ya none, guhitamo uburyo bukwiye bwo gutumanaho ni urufunguzo. RS422 na RS485 nibintu bibiri byingenzi. Bakoresha ibimenyetso bitandukanye kugirango bakore neza.
RS422 na RS485 byombi bifasha kohereza amakuru kure. Bakoresha insinga zigoretse hamwe nibimenyetso bitandukanye. Ibi bituma ihererekanyamakuru ryizewe, ndetse no ahantu huzuye urusaku. Ni ingenzi mu nganda nyinshi no mu bucuruzi.
Ibyingenzi
1.RS422 na RS485 nibipimo byingenzi byitumanaho.
2.Ibimenyetso bitandukanye kandi bigoretse insinga byongera itumanaho.
3.Ibipimo ngenderwaho nibyingenzi mugukwirakwiza intera ndende.
4.Byombi RS422 na RS485 nibyiza mugabanya urusaku no gukomeza ubudakemwa bwibimenyetso.
5.Imikoreshereze yabo ikoreshwa mubikorwa bitandukanye byinganda nubucuruzi.
Incamake ya RS422
RS422 nigipimo gikomeye cyitumanaho rikurikirana. Itanga amakuru yihuse kandi ikora neza intera ndende. Ifite igipimo gito cyamakosa. Reka turebe icyatuma RS422 idasanzwe, inyungu zayo, n'aho ikoreshwa.
RS422 Ibipimo nibisobanuro
Ibipimo bya RS422 bifite amashanyarazi asobanutse yo kohereza amakuru. Ikoresha voltage yo hasi kugirango ibike ingufu. Imashini ya RS422 ikoresha ibimenyetso bitandukanye kugirango irwanye urusaku no kwerekana ibimenyetso.
Dore ibyingenzi byingenzi byamashanyarazi kuri RS422:
Level Urwego rutandukanye rwa voltage: ± 2V kugeza ± 6V
Rate Igipimo ntarengwa cyamakuru: 10 Mbps
Uburebure bwa kabili ntarengwa: metero 1200
Ibyiza bya RS422 mubitumanaho bikurikirana
RS422 nibyiza kubiganiro byuzuye-duplex. Ibi bivuze ko ishobora kohereza no kwakira amakuru icyarimwe. Nibyiza kubwigihe cyo guhanahana amakuru. Byongeye, nibyiza mukurwanya ibimenyetso byerekana, bityo bikora neza mumwanya muremure.
Gusaba RS422 mu nganda
RS422 ikoreshwa mu nganda nyinshi kuko yizewe kandi ikora neza. Byakoreshejwe muri:
Systems Sisitemu yo kugenzura inganda zerekana ibimenyetso neza
Inganda zikoreshwa muburyo bwo guhuza amakuru
Itumanaho ryo gukoresha intera ndende
Devices Ibikoresho byubuvuzi byitumanaho rihoraho
Incamake ya RS485
Igipimo cya RS485 ni ukuzamura kuva RS422, kugenewe gukoreshwa mu nganda no mu bucuruzi. Ifasha igice cya-duplex itumanaho, bigatuma guhanahana amakuru hagati yibikoresho kumurongo umwe ukora neza.
RS485 Ibipimo nibisobanuro
RS485 irashobora guhuza ibikoresho bigera kuri 32 kuri bisi imwe binyuze mumatumanaho menshi. Ikoresha ibimenyetso bitandukanye kugirango igabanye ibibazo hamwe no kohereza amakuru kure. Ibipimo bikubiyemo ibisobanuro birambuye kuri voltage ikora, urwego rwibimenyetso, nigihe cyo kwemeza ko ibikoresho bikora neza.
Ibyingenzi byingenzi ninyungu za RS485
RS485 igaragara cyane mu itumanaho ryayo rya kabiri-duplex, itanga uburyo bubiri bwo kohereza amakuru kumurongo umwe winsinga. Ibi byoroshya imiyoboro ya cabling kandi igabanya ibiciro. Itanga kandi ibimenyetso bikomeye byubudahangarwa bwurusaku, byemeza ubudakemwa bwamakuru ahantu huzuye urusaku. Ibi nibyingenzi mubikorwa byinganda aho kwivanga bisanzwe.
Gukoresha Imanza Zisanzwe kuri RS485
RS485 irazwi cyane muri sisitemu ikeneye itumanaho ryizewe intera ndende. Ikoreshwa mukubaka automatike, kugenzura HVAC, hamwe nurusobe rwinganda. Ubushobozi bwayo bwo gushyigikira ibikoresho byinshi kumurongo umwe byoroshye kwagura sisitemu nta mpinduka nini.
Nibyingenzi kandi muri sisitemu ya CCTV no gupima kure. Hano, ubunyangamugayo bwamakuru no gutakaza ibimenyetso bike ni ngombwa.
Itandukaniro ryingenzi hagati ya RS422 na RS485
Ni ngombwa kumenya itandukaniro riri hagati ya RS422 na RS485 kugirango itumanaho rikurikirane. Itandukaniro ryerekana muburyo bwabo, uko amakuru yimuka, ubwiza bwibimenyetso, kurwanya urusaku, nuburyo bwohereza amakuru byihuse kandi byihuse.
Itumanaho Topology: Ingingo-Kuri-Ingingo vs Multi-Igitonyanga
RS422 ikozwe muburyo bwo gutumanaho. Nibyiza guhuza bitaziguye hagati yibikoresho bibiri. RS485, ariko, ni iyitumanaho ryinshi. Ireka ibikoresho byinshi bikoresha bisi imwe, itunganijwe neza.
Icyerekezo cyo kohereza amakuru: Byuzuye-Duplex vs Igice-Duplex
RS422 ishyigikira itumanaho ryuzuye. Ibi bivuze ko ishobora kohereza no kwakira amakuru icyarimwe. RS485 irashobora gukora muburyo bwuzuye-duplex RS485 hamwe na kimwe cya kabiri cya RS485. Ibi biratanga guhinduka kubikenewe bitandukanye.
Ikimenyetso cy'ubunyangamugayo n'ubudahangarwa bw'urusaku
RS422 na RS485 zombi zifite ubudahangarwa bw'urusaku bitewe n'ibimenyetso bitandukanye. Ariko, RS485 igizwe nibitonyanga byinshi bishobora guhura n urusaku rwinshi kuruta RS422. Iki nikintu cyo gutekerezaho ahantu huzuye urusaku.
Intera nubushobozi bwihuta
RS422 na RS485 birashobora kohereza amakuru byihuse mugihe gito. Ariko, ziratandukanye intera ndende. RS485 ikora neza, hamwe nintera ntarengwa. Nibyiza kubikoresho birebire kandi byihuse amakuru akenewe.
RS422 vs RS485: Ninde wahitamo?
Guhitamo hagati ya RS422 na RS485 birashobora kugorana. Biterwa nibintu byinshi byingenzi nicyo inganda zawe zikeneye. Kumenya icyingenzi ni ngombwa muguhitamo neza.
Ibintu ugomba gusuzuma muguhitamo hagati ya RS422 na RS485
Mugihe utoranya hagati ya RS422 na RS485, tekereza kubintu bike. Reba intera yohereza amakuru, protocole y'itumanaho ukeneye, urwego rwurusaku, hamwe nurusobe. RS422 ninziza kubiganiro-by-itumanaho intera ndende. RS485, kurundi ruhande, nibyiza guhuza ibikoresho byinshi kumurongo umwe.
Inganda-Ibyifuzo byihariye (Automation yinganda, SCADA, nibindi)
Mubice nka automatike yinganda na sisitemu ya SCADA, ibipimo byombi bifite aho bihurira. RS422 ni hejuru cyane ahantu hagaragara ibimenyetso bisukuye ni urufunguzo. Ikoresha ibimenyetso bito bito bito byerekana ibimenyetso. RS485, ariko, ni ukujya gushiraho hamwe nibikoresho byinshi, byoroshye gukurikirana no kugenzura kure.
Uburyo bwo Guhitamo Ukurikije Ibisabwa
Intera yo kohereza amakuru: RS422 irashobora kurenga RS485.
Amasezerano y'itumanaho: Reba niba bihuye na sisitemu yawe ya none na protocole.
Ubudahangarwa bw'urusaku: RS422 nibyiza kurwanya urusaku bitewe nibimenyetso byayo bitandukanye.
Igishushanyo mbonera: RS485 ninziza kumurongo ufite ibikoresho byinshi hamwe nuburyo bworoshye.
Urebye neza izi ngingo, urashobora guhitamo uburyo bwiza kubyo ukeneye.

RS232 ikora neza kubirometero bigufi no guhuza byoroshye. Ariko, RS422 na RS485 nibyiza kubirometero ndende no gushiraho bigoye. Batanga kwizerwa no kurinda imirongo yamakuru.
Umwanzuro
Mugihe dusoza ibisobanuro birambuye, itandukaniro ryingenzi hagati ya RS422 na RS485 rirasobanutse. Isohora ryuruhererekane rifite inyungu zidasanzwe kandi rikoreshwa, bigatuma riba urufunguzo muri protocole yinganda. Kumenya amashanyarazi yabo yongerera imbaraga itumanaho hamwe nibikoresho byizewe kubikorwa bigoye.
RS422 irabagirana hamwe na duplex yuzuye kandi intera ndende. Nibyiza kubiganiro byukuri-ku-ngingo. Kurundi ruhande, RS485 igice cya kabiri-duplex igishushanyo ninkunga ya node nyinshi ninziza kuri sisitemu ikenera guhuza byoroshye no gukora byizewe intera ndende.
Muri make, gutora hagati ya RS422 vs RS485 biterwa numushinga wawe ukeneye. Niba ari kuri inganda za PC, uruganda rukora mudasobwa, cyangwa yashyizwemo na mudasobwa ikora, ukoresheje ibi bice byuruhererekane neza byerekana neza imikorere yo hejuru hamwe nibikoresho byizewe. Byongeye, sisitemu nka inganda za PC zo kureba imashini cyangwa mini rugged PC Biterwa nuburyo bwiza bwitumanaho kugirango ukomeze imikorere myiza.
Mugihe protocole yinganda ikomeza gutera imbere, RS422 na RS485 bizakomeza kugira uruhare runini mugutumanaho neza kandi neza muri sisitemu yubu.
