Rau kev sib txuas ua ke hauv tsev uas txuas nrog, Wi-Fi yog qhov kev xaiv uas muaj nyob txhua qhov chaw. Nws zoo kom muaj lawv nrog kev sib txuas Wi-Fi ruaj ntseg. Qhov ntawd tuaj yeem yooj yim mus nrog koj lub router hauv tsev uas twb muaj lawm thiab koj tsis tas yuav yuav lub smart hub cais los ntxiv cov khoom siv rau hauv.

Tiam sis Wi-Fi kuj muaj nws cov kev txwv. Cov khoom siv uas tsuas yog khiav ntawm Wi-Fi xav tau kev them nyiaj ntau zaus. Xav txog cov laptops, smartphones, thiab txawm tias cov neeg hais lus ntse. Dhau li ntawm qhov ntawd, lawv tsis muaj peev xwm tshawb pom tus kheej thiab koj yuav tsum sau tus password rau txhua lub cuab yeej Wi-Fi tshiab. Yog tias qee qhov laj thawj Internet ceev qis dua, nws tuaj yeem ua rau koj qhov kev paub hauv tsev ntse tag nrho mus rau qhov phem heev.

Cia peb tshawb nrhiav qhov zoo thiab qhov tsis zoo ntawm kev siv Zigbee lossis Wi-Fi. Kev paub txog qhov sib txawv no yog qhov tseem ceeb vim nws tuaj yeem cuam tshuam rau koj qhov 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 wireless kev sib txuas lus technologies raws li 2.4GHz band. Hauv tsev ntse, tshwj xeeb tshaj yog hauv kev txawj ntse tag nrho lub tsev, kev xaiv ntawm kev sib txuas lus protocol ncaj qha cuam tshuam rau kev ncaj ncees thiab kev ruaj khov ntawm cov khoom.

Piv txwv li, Wifi siv rau kev sib kis ceev ceev, xws li kev nkag mus rau hauv Is Taws Nem wireless; Zigbee yog tsim los rau kev sib kis ceev qis, xws li kev sib cuam tshuam ntawm ob yam khoom ntse.

Txawm li cas los xij, ob lub thev naus laus zis no yog raws li cov qauv wireless sib txawv: Zigbee yog raws li IEEE802.15.4, thaum Wifi yog raws li IEEE802.11.

Qhov txawv yog tias Zigbee, txawm hais tias tus nqi kis tau qis, qhov siab tshaj plaws tsuas yog 250kbps, tab sis kev siv hluav taws xob tsuas yog 5mA; Txawm hais tias Wifi muaj tus nqi kis tau siab, 802.11b, piv txwv li, tuaj yeem ncav cuag 11Mbps, tab sis kev siv hluav taws xob yog 10-50mA.

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

2. Kev sib koom ua ke

Vim tias Zigbee thiab Wifi muaj lawv qhov zoo thiab qhov tsis zoo, puas siv tau ua ke? Nws zoo li cov txheej txheem CAN thiab LIN hauv tsheb, txhua tus ua haujlwm rau ib lub kaw lus sib txawv.

Nws yog qhov ua tau raws li kev xav, thiab kev sib raug zoo tsim nyog kawm ntxiv rau kev txiav txim siab txog tus nqi. Vim tias ob qho qauv nyob hauv 2.4ghz band, lawv tuaj yeem cuam tshuam nrog ib leeg thaum xa ua ke.

Yog li ntawd, yog tias koj xav xa Zigbee thiab Wifi tib lub sijhawm, koj yuav tsum ua haujlwm zoo hauv kev npaj channel kom ntseeg tau tias cov channel ntawm ob qho protocols yuav tsis sib tshooj thaum lawv ua haujlwm. Yog tias koj tuaj yeem ua tiav kev ruaj khov thiab nrhiav qhov sib npaug ntawm tus nqi, Zigbee + Wifi txoj kev npaj yuav dhau los ua qhov kev xaiv zoo. Tau kawg, nws nyuaj rau hais tias seb Thread protocol puas yuav noj ob qho tib si ntawm cov qauv no.

Xaus lus

Nruab nrab ntawm Zigbee thiab Wifi, tsis muaj leej twg zoo dua lossis phem dua, thiab tsis muaj tus yeej kiag li, tsuas yog qhov tsim nyog xwb. Nrog rau kev txhim kho thev naus laus zis, peb kuj zoo siab pom kev koom tes ntawm ntau yam kev sib txuas lus hauv thaj chaw ntawm lub tsev ntse los daws ntau yam teeb meem hauv thaj chaw ntawm kev sib txuas lus hauv tsev ntse.
