Rau kev sib koom ua ke hauv tsev sib txuas, Wi-Fi tau pom tias yog qhov kev xaiv dav dav. Nws yog qhov zoo kom muaj lawv nrog kev ruaj ntseg Wi-nkaus khub. Qhov ntawd tuaj yeem yooj yim mus nrog koj lub tsev router uas twb muaj lawm thiab koj tsis tas yuav yuav ib lub hub ntse cais ntxiv cov khoom siv hauv.

Tab sis Wi-Fi kuj muaj nws cov kev txwv. Cov khoom siv uas khiav ntawm Wi-Fi nkaus xwb yuav tsum tau them nyiaj ntau zaus. Xav txog lub laptops, smartphones, thiab txawm tias cov neeg hais lus ntse. Tsis tas li ntawd, lawv tsis muaj peev xwm nrhiav tau tus kheej thiab koj yuav tsum sau tus password rau txhua lub cuab yeej Wi-Fi tshiab. Yog tias vim li cas Internet ceev qis dua, nws tuaj yeem tig koj qhov kev paub hauv tsev ntse mus rau npau suav phem.

Cia peb tshawb nrhiav qhov zoo thiab qhov tsis zoo ntawm kev siv Zigbee lossis Wi-Fi. Paub txog qhov sib txawv no yog qhov tseem ceeb heev vim nws tuaj yeem cuam tshuam koj cov kev txiav txim siab yuav khoom rau cov khoom siv hauv tsev ntse.

1. Kev siv hluav taws xob

Zigbee thiab Wifi yog ob qho tib si kev sib txuas lus wireless raws li 2.4GHz band. Hauv tsev ntse, tshwj xeeb tshaj yog nyob rau hauv tag nrho lub tsev txawj ntse, kev xaiv ntawm kev sib txuas lus raws tu qauv ncaj qha cuam tshuam rau kev ncaj ncees thiab stability ntawm cov khoom.

Piv txwv li, Wifi yog siv rau kev sib kis ceev, xws li kev siv internet wireless; Zigbee yog tsim los rau kev sib kis tus nqi qis, xws li kev sib cuam tshuam ntawm ob yam khoom ntse.

Txawm li cas los xij, ob lub thev naus laus zis yog raws li cov qauv sib txawv wireless: Zigbee yog raws li IEEE802.15.4, thaum Wifi yog raws li IEEE802.11.

Qhov txawv yog Zigbee, txawm hais tias tus kis tau tus mob tsawg, qhov siab tshaj plaws tsuas yog 250kbps, tab sis lub zog siv tsuas yog 5mA; Txawm hais tias Wifi muaj qhov sib kis tau zoo, 802.11b, piv txwv li, tuaj yeem ncav cuag 11Mbps, tab sis lub zog siv yog 10-50mA.

Yog li ntawd, rau kev sib txuas lus ntawm lub tsev ntse, kev siv hluav taws xob tsawg yog pom tseeb dua, vim tias cov khoom xws li cov ntsuas kub, uas yuav tsum tau tsav los ntawm cov roj teeb ib leeg, kev siv hluav taws xob tsim yog qhov tseem ceeb heev. Tsis tas li ntawd, Zigbee muaj qhov pom tseeb zoo dua piv nrog Wifi, tus naj npawb ntawm cov kab sib txuas yog siab li 65,000; Wifi tsuas yog 50. Zigbee yog 30 milliseconds, Wifi yog 3 vib nas this. Yog li, koj puas paub vim li cas cov neeg muag khoom hauv tsev ntse feem ntau nyiam Zigbee, thiab tau kawg Zigbee tau sib tw nrog cov khoom xws li Xov thiab Z-Wave.

2. Kev sib koom ua ke

Txij li thaum Zigbee thiab Wifi muaj lawv qhov zoo thiab qhov tsis zoo, lawv puas tuaj yeem siv ua ke? Nws zoo li CAN thiab LIN raws tu qauv hauv tsheb, txhua qhov ua haujlwm sib txawv.

Nws yog theoretically ua tau, thiab compatibility yog tsim nyog kawm ntxiv rau cov nqi txiav txim siab. Vim hais tias ob qho tib si qauv yog nyob rau hauv 2.4ghz band, lawv tuaj yeem cuam tshuam ib leeg thaum siv ua ke.

Yog li ntawd, yog tias koj xav xa Zigbee thiab Wifi tib lub sijhawm, koj yuav tsum ua txoj haujlwm zoo hauv kev npaj channel kom ntseeg tau tias cov channel ntawm ob txoj cai yuav tsis sib tshooj thaum lawv ua haujlwm. Yog tias koj tuaj yeem ua tiav kev ruaj ntseg thiab nrhiav qhov sib npaug ntawm tus nqi, Zigbee + Wi-Fi scheme yuav dhau los ua qhov kev xaiv zoo Tau kawg, nws nyuaj rau hais tias Xov Tooj raws tu qauv yuav ncaj qha noj ob qho tib si ntawm cov qauv no.

Xaus

Ntawm Zigbee thiab Wifi, tsis muaj ib qho zoo dua lossis phem dua, thiab tsis muaj tus yeej, tsuas yog tsim nyog. Nrog rau kev txhim kho thev naus laus zis, peb kuj zoo siab pom kev sib koom tes ntawm ntau yam kev sib txuas lus raws tu qauv hauv lub tsev ntse kom daws tau ntau yam teeb meem hauv kev sib txuas lus hauv tsev ntse.
