Amakuru

Byombi Multiplexers na Power Dividers nibikoresho bifasha kwagura umubare wa antene ishobora guhuzwa nicyambu cyumusomyi. Imwe mu nyungu nyamukuru nukugabanya ikiguzi cya porogaramu ya UHF RFID mugabana ibyuma bihenze. Muri iyi nyandiko ya blog, turasobanura itandukaniro nibigomba kwitabwaho muguhitamo igikoresho gikwiye cyo gusaba.

Nibihe bigizwe na de-multiplexer?

Kugirango twumve icyo umusomyi wa RFID Multiplexer aricyo tuzahita dusobanura byihuse intego rusange ya multiplexers (mux) na de-multiplexers (de-mux).

Multiplexer nigikoresho gihitamo kimwe mubimenyetso byinshi byinjira hanyuma kikohereza kubisohoka.

Demultiplexer nigikoresho cyohereza ibimenyetso byinjira muri kimwe mubisubizo byinshi.

Byombi bigizwe na de-multiplexer bisaba guhinduranya kugirango uhitemo ibyinjira na / cyangwa ibisohoka. Ihinduranya rifite imbaraga, bityo mux na de-mux nibikoresho bikora.

Niki kigizwe numusomyi wa RFID?

Umusomyi wa RFID umusomyi ni igikoresho gihuza mux na de-mux. Igizwe numurongo umwe winjiza / ibisohoka nibisohoka / ibyambu byinshi. Icyambu kimwe cya mux / de-mux gisanzwe gihujwe numusomyi wa RFID mugihe ibyambu byinshi byeguriwe antenne.

Irashobora kohereza ibimenyetso kuva ku cyambu cy'abasomyi ba RFID kuri kimwe mu byambu bisohoka cyangwa ikohereza ibimenyetso kuva kuri kimwe mu byambu byinshi byinjira ku cyambu cy'abasomyi ba RFID.

Ihinduramiterere yubatswe yita ku kimenyetso gihinduranya hagati yicyambu nigihe cyo guhinduranya.

RFID multiplexer ituma antenne ihuza byinshi ku cyambu kimwe cyumusomyi wa RFID. Ubunini bwikimenyetso cyahinduwe ntabwo bugira ingaruka ku buryo bugaragara, hatitawe ku mubare w’ibyambu muri mux / de-mux.

Muri ubwo buryo, 8-port ya RFID multiplexer, kurugero, irashobora kwagura umusomyi wibyambu 4 mumasomero 32 ya RFID.

Ibirango bimwe na bimwe bita mux yabo ihuriro.

Niki kigabanya imbaraga (power power) hamwe nimbaraga zihuza imbaraga?

Igabana imbaraga (splitter) nigikoresho kigabanya imbaraga. Icyambu cya 2-icyuma kigabanya imbaraga zinjiza mubisubizo bibiri. Ubunini bwimbaraga zigabanyijemo kabiri ibyasohotse.

Imbaraga zigabanya imbaraga zitwa imbaraga zihuza iyo zikoreshwa muburyo butandukanye.

Hano haribintu byihuse byerekana itandukaniro riri hagati ya mux nigabanya imbaraga:

MUX	IMBARAGA Z'UBUBASHA
Mux izahorana imbaraga zo gutakaza ibyambu utitaye kumubare wibyambu. Icyambu 4, 8-icyambu, na 16-port mux ntibizagira igihombo gitandukanye kuri buri cyambu.	Imbaraga zigabanya imbaraga muri ½ cyangwa ¼ bitewe numubare wibyambu bihari. Kugabanuka kwingufu nini kugaragara kuri buri cyambu uko umubare wibyambu wiyongereye.
Mux ni igikoresho gikora. Birasaba imbaraga za DC no kugenzura ibimenyetso kugirango bikore.	Igabana ryingufu nigikoresho cyoroshye. Ntabwo ikeneye inyongera yinyongera kuruta iyinjira rya RF.
Ntabwo ibyambu byose biri mu byambu byinshi bifunguye icyarimwe. Imbaraga za RF zahinduwe hagati yicyambu. Antenna imwe ihujwe gusa izahabwa ingufu icyarimwe, kandi umuvuduko wo guhinduranya urihuta kuburyo antene itazabura tagi yasomwe.	Ibyambu byose mumashanyarazi menshi-bigabanya imbaraga zingana kandi icyarimwe.
Kwigunga cyane hagati yicyambu kugerwaho. Ibi nibyingenzi kugirango wirinde kwambukiranya tagi hagati ya antene. Kwigunga mubisanzwe biri murwego rwa 35 dB cyangwa irenga.	Icyambu cyo kwigunga ni gito ugereranije na Mux. Icyambu gisanzwe cyo kwigunga ni 20 dB cyangwa irenga. Ikirangantego gisomwa gishobora kuba ikibazo.
Ifite bike cyangwa nta ngaruka muri antenna ya beam cyangwa guhagarika.	Iyo amashanyarazi atakoreshejwe muburyo bukwiye, imirima ya RF irashobora guhagarikwa, kandi urumuri rwa RF antenna rushobora guhinduka kuburyo bugaragara.
Nta buhanga bwa RF busabwa gushiraho Mux. Mux igomba kugenzurwa na software ya RFID umusomyi.	Ubuhanga bwa RF ni ngombwa gushiraho amashanyarazi no kugera kubisubizo byakazi. Igaburo ryamashanyarazi ridashyizwemo nabi ryangiza cyane imikorere ya RF.
Nta guhindura antenne yihariye birashoboka	Guhindura antenne yihariye birashoboka. Antenna`s beam-ubugari, inguni ya beam, nibindi birashobora guhinduka.

Si Chuan Keenlion Microwave ihitamo rinini, ikubiyemo imirongo kuva kuri 0.5 kugeza kuri 50 GHz. Byaremewe gukora kuva kuri 10 kugeza 200 watts yinjiza muri sisitemu yohereza 50-ohm. Ibishushanyo bya Cavity birakoreshwa, kandi bigashyirwa mubikorwa byiza.

Ibyinshi mubicuruzwa byacu byateguwe kuburyo bishobora gukururwa bikamanikwa kuri hoteri, nibiba ngombwa. Biranga kandi amplitude idasanzwe hamwe nuburinganire bwicyiciro, bifite imbaraga zo gukoresha imbaraga nyinshi, urwego rwiza rwo kwigunga kandi ruzana hamwe nububiko.

Turashobora kandi guhitamo ibicuruzwa bya rf pasiporo dukurikije ibyo usabwa. Urashobora kwinjira muriKumenyekanishaurupapuro kugirango utange ibisobanuro ukeneye.
