Hom kev sib txuas lus yog hais txog hom kev ua haujlwm lossis hom teeb liab kis ntawm ob tog kev sib txuas lus.
1. Simplex, ib nrab-duplex, thiab kev sib txuas lus puv-duplex
Rau kev sib txuas lus point-to-point, raws li kev taw qhia thiab lub sijhawm ntawm kev xa xov, hom kev sib txuas lus tuaj yeem muab faib ua simplex, ib nrab-duplex thiab puv-duplex kev sib txuas lus.
(1) Kev sib txuas lus yooj yim txhais tau hais tias cov lus tuaj yeem xa mus rau hauv ib qho kev taw qhia nkaus xwb, raws li pom hauv daim duab 1-6(a).
Tsuas yog ib qho ntawm ob tog kev sib txuas lus tuaj yeem xa tau, thiab lwm tus tuaj yeem tau txais, xws li kev tshaj tawm xov xwm, telemetry, chaw taws teeb tswj, wireless paging, thiab lwm yam. (2) Hauv Half-duplex kev sib txuas lus hom, ob tog tuaj yeem xa thiab txais cov lus, tab sis tsis tuaj yeem xa thiab txais cov lus tib lub sijhawm, raws li pom hauv daim duab 1-6(b). Piv txwv li, kev siv tib cov neeg nqa khoom zaus ntawm cov khoom siv walkie-talkies, kev nug thiab kev tshawb nrhiav.
(3) Kev sib txuas lus puv puv yog hais txog hom kev ua haujlwm uas ob tog tuaj yeem xa thiab tau txais cov lus tib lub sijhawm. Feem ntau hais lus, tag nrho-duplex kev sib txuas lus channel yuav tsum yog ob txoj kev channel, raws li pom hauv daim duab 1-6(c). Lub xov tooj yog ib qho piv txwv ntawm kev sib txuas lus puv npo, uas ob tog tuaj yeem hais lus thiab mloog tib lub sijhawm. Cov ntaub ntawv ceev ceev sib txuas lus ntawm cov khoos phis tawj yog tib txoj kev.
2. Parallel kis tau tus mob thiab serial kis tau tus mob
Hauv kev sib txuas lus cov ntaub ntawv (tsuas yog kev sib txuas lus ntawm cov khoos phis tawj lossis lwm yam khoom siv digital davhlau ya nyob twg), raws li cov qauv sib txawv ntawm cov ntaub ntawv cov cim, nws tuaj yeem muab faib ua qhov sib npaug thiab sib kis.
(1) Parallel kis tau tus mob yog ib txhij kis tau tus mob ntawm ib theem ntawm digital code ntsiab sawv cev rau cov ntaub ntawv nyob rau hauv ib pab pawg neeg ntawm ob los yog ntau tshaj parallel channels. Piv txwv li, binary sequence ntawm "0" thiab "1" xa los ntawm lub computer yuav kis tau ib txhij ntawm n parallel channels nyob rau hauv daim ntawv ntawm n cov cim rau ib pab pawg neeg. Nyob rau hauv txoj kev no, n cov cim hauv pob ntawv tuaj yeem kis tau los ntawm ib lub cuab yeej mus rau lwm qhov hauv lub moos ntaus. Piv txwv li, cov cim 8-ntsis tuaj yeem xa mus rau qhov sib npaug ntawm 8 raws, raws li pom hauv daim duab 1-7.
Qhov zoo ntawm kev sib kis sib txuas yog kom txuag tau lub sijhawm sib kis thiab ceev. Qhov tsis zoo yog tias n kev sib txuas lus yuav tsum muaj thiab tus nqi siab, yog li nws feem ntau tsuas yog siv rau kev sib txuas lus luv luv ntawm cov khoom siv, xws li kev xa cov ntaub ntawv ntawm cov khoos phis tawj thiab cov tshuab luam ntawv.
(2) Serial kis tau tus mob yog hais txog kev sib kis ntawm ib ntu ntawm cov cim digital ntawm cov channel hauv ib txoj hauv kev, ib lub cim tom qab lwm qhov, raws li pom hauv daim duab 1-8. Qhov no feem ntau yog siv rau kev sib kis digital mus ntev.
Cov saum toj no yog "kev sib txuas lus hom" tsab xov xwm coj los rau koj los ntawm Shenzhen HDV Phoelectron Technology LTD., thiab HDV yog ib lub tuam txhab tshwj xeeb hauv kev sib txuas lus kho qhov muag raws li cov khoom siv tseem ceeb, lub tuam txhab tsim khoom: ONU series, optical module series,OLT series, transceiver series yog kub series ntawm cov khoom.
