Muaj ntau thiab ntau wireless modules nyob rau hauv kev ua lag luam, tab sis lawv tuaj yeem muab faib ua peb pawg:
1. NUG superheterodyne module: peb tuaj yeem siv los ua cov chaw taws teeb tswj yooj yim thiab cov ntaub ntawv xa mus;
2. Wireless transceiver module: Nws tsuas yog siv lub microcomputer nkaus xwb los tswj cov wireless module xa thiab txais cov ntaub ntawv.Cov qauv siv feem ntau yog FSK thiab GFSK;
3. Lub wireless cov ntaub ntawv kis tau tus mob feem ntau yog siv cov cuab yeej serial chaw nres nkoj kom tau txais thiab xa cov ntaub ntawv, uas yooj yim rau cov neeg siv khoom.Wireless modules ntawm kev ua lag luam tam sim no tau siv dav, nrog zaus ntawm 230MHz, 315MHz, 433MHz, 490MHz, 868MHz, 915MHz, 2.4GHz, thiab lwm yam.
Kab lus no feem ntau qhia txog qhov sib piv ntawm 433M thiab 2.4G wireless modules.Ua ntej tshaj plaws, peb yuav tsum paub tias qhov ntau zaus ntawm 433M yog 433.05 ~ 434.79MHz, thaum lub sijhawm ntau ntawm 2.4G yog 2.4 ~ 2.5GHz.Lawv yog tag nrho cov ntawv tso cai tsis pub muaj ISM (kev lag luam, kev tshawb fawb thiab kev kho mob) qhib ntau zaus hauv Suav teb.Nws tsis yog tsim nyog los siv cov zaus bands.Yuav tsum tau thov kev tso cai los ntawm kev tswj hwm hauv xov tooj cua hauv zos, yog li ob pawg no tau siv dav.
433MHz yog dab tsi?
Lub 433MHz wireless transceiver module siv high-frequency xov tooj cua zaus tshuab, yog li nws tseem hu ua RF433 xov tooj cua zaus me me module.Nws yog tsim los ntawm ib leeg IC xov tooj cua zaus pem hauv ntej kawg uas tsim los ntawm tag nrho cov digital technology thiab ATMEL's AVR ib leeg-chip microcomputer.Nws tuaj yeem xa cov ntaub ntawv teeb liab ntawm kev kub ceev, thiab nws tuaj yeem ntim, kuaj thiab kho cov ntaub ntawv xa mus wirelessly.Cov khoom yog tag nrho cov qauv kev lag luam, ruaj khov thiab txhim khu kev qha hauv kev ua haujlwm, me me thiab yooj yim rau nruab.Nws yog tsim rau ntau yam kev lag luam xws li tswb kev ruaj ntseg, wireless tsis siv neeg ntsuas ntsuas nyeem, tsev thiab kev lag luam automation, chaw taws teeb tswj chaw taws teeb, wireless cov ntaub ntawv xa mus thiab lwm yam.
433M tau txais kev nkag siab zoo thiab kev ua haujlwm zoo diffraction.Peb feem ntau siv 433MHz cov khoom siv los siv cov kev sib txuas lus tswv-qib.Nyob rau hauv txoj kev no, tus tswv-tus qhev topology tiag tiag yog lub tsev ntse, uas muaj qhov zoo ntawm cov qauv sib txuas yooj yim, kev teeb tsa yooj yim, thiab lub sijhawm luv zog.433MHz thiab 470MHz tam sim no tau siv dav hauv kev lag luam ntse nyeem ntawv.
Daim ntawv thov ntawm 433MHz hauv tsev ntse
1. Kev tswj teeb pom kev zoo
Lub wireless xov tooj cua zaus teeb pom kev zoo tswj qhov system yog tsim los ntawm lub ntse vaj huam sib luag hloov thiab lub dimmer.Lub dimmer yog siv los xa thiab txais cov lus txib.Cov lus txib raug xa los ntawm xov tooj cua es tsis txhob siv cov kab hluav taws xob hauv tsev.Txhua lub vaj huam sib luag hloov yog nruab nrog cov chaw taws teeb tswj kev txheeb xyuas qhov sib txawv.Cov lis dej num no siv 19-ntsis paub txog technology los pab kom tus neeg txais kev pom zoo txheeb xyuas txhua qhov lus txib.Txawm hais tias cov neeg nyob sib ze siv tib lub sijhawm, yuav tsis muaj kev sib kis tsis raug vim cuam tshuam los ntawm lawv cov chaw taws teeb tswj.
2. Wireless Smart Socket
Lub wireless ntse socket series feem ntau siv wireless xov tooj cua zaus siv tshuab kom paub txog cov chaw taws teeb tswj ntawm lub zog ntawm cov khoom siv tswj tsis tau chaw taws teeb (xws li lub tshuab rhaub dej, hluav taws xob kiv cua, thiab lwm yam), uas tsis tsuas yog ntxiv cov haujlwm ntawm wireless chaw taws teeb tswj rau cov no. cov khoom siv, tab sis kuj txuag lub zog rau qhov loj tshaj plaws thiab ua kom muaj kev nyab xeeb.
3. Kev tswj cov khoom siv ntaub ntawv
Kev tswj cov khoom siv ntaub ntawv yog ib qho kev tswj xyuas cov chaw taws teeb uas muaj ntau yam uas sib txuas nrog infrared tswj thiab wireless tswj.Nws tuaj yeem tswj tau txog li tsib yam khoom siv infrared (xws li: TV, cua txias, DVD, lub zog amplifier, curtains, thiab lwm yam) thiab cov khoom siv wireless xws li keyboards thiab sockets.Cov ntaub ntawv tswj cov khoom siv tuaj yeem hloov cov lej ntawm cov chaw taws teeb tswj ntawm cov khoom siv hluav taws xob zoo tib yam los ntawm kev kawm los hloov cov khoom siv hluav taws xob qub.Nyob rau tib lub sijhawm, nws tseem yog wireless chaw taws teeb tswj, uas tuaj yeem xa cov teeb liab tswj nrog lub zaus ntawm 433.92MHz, yog li nws tuaj yeem tswj cov keyboards ntse, ntse ntse thiab wireless infrared transponders hauv qhov zaus band.
Lub 2.4GHz daim ntawv thov taw tes yog kev sib txuas lus raws tu qauv tsim los ntawm nws qhov kev sib kis ceev ceev.
Tag nrho hauv tag nrho, peb tuaj yeem xaiv cov modules nrog ntau zaus raws li kev sib txuas sib txawv.Yog tias txoj kev sib txuas lus yog qhov yooj yim thiab cov kev xav tau yooj yim, ib tus tswv muaj ntau tus qhev, tus nqi qis, thiab kev siv ib puag ncig nyuaj, peb tuaj yeem siv 433MHz wireless module;hais lus, yog tias lub network topology yog qhov nyuaj thiab ua haujlwm Ntau yam khoom siv nrog lub zog muaj zog, kev siv hluav taws xob tsawg, kev txhim kho yooj yim, thiab 2.4GHz networking muaj nuj nqi yuav yog qhov kev xaiv zoo tshaj plaws.
