Tsev automation yog tag nrho cov npau taws heev hnub no. Muaj ntau ntau yam sib txawv wireless raws tu qauv tawm muaj, tab sis cov uas feem ntau cov neeg tau hnov ​​​​txog yog WiFi thiab Bluetooth vim hais tias cov no yog siv nyob rau hauv pab kiag li lawm uas peb muaj ntau, mobile xov tooj thiab computers. Tab sis muaj lwm qhov thib peb hu ua ZigBee uas yog tsim los rau kev tswj thiab ntsuas. Ib yam uas tag nrho peb muaj sib xws yog tias lawv ua haujlwm ntawm tib zaus - ntawm lossis txog 2.4 GHz. Qhov zoo sib xws yuav xaus rau ntawd. Yog li dab tsi yog qhov txawv?

WIFI

WiFi yog ib qho kev hloov ncaj qha rau ib lub xov tooj Ethernet cable thiab siv tib lub sijhawm kom tsis txhob khiav ntawm txhua qhov chaw. Qhov txiaj ntsig zoo ntawm WiFi yog tias koj tuaj yeem tswj hwm thiab saib xyuas koj lub tsev cov khoom siv ntse los ntawm txhua qhov chaw hauv ntiaj teb ntawm smartphone, ntsiav tshuaj, lossis laptop. Thiab, vim yog Wi-Fi qhov chaw nyob, muaj ntau yam khoom siv ntse uas ua raws li tus qauv no. Nws txhais tau hais tias lub PC tsis tas yuav tsum tau tso tseg kom nkag mus rau lub cuab yeej siv WiFi. Cov khoom siv chaw taws teeb xws li IP koob yees duab siv WiFi kom lawv tuaj yeem txuas nrog lub router thiab nkag mus thoob plaws Is Taws Nem. WiFi muaj txiaj ntsig tab sis tsis yooj yim rau kev siv tshwj tsis yog tias koj tsuas yog xav txuas lub cuab yeej tshiab rau koj lub network uas twb muaj lawm.

Ib qho downside yog tias Wi-Fi-tswj ntse cov cuab yeej zoo li yuav kim dua li cov uas ua haujlwm hauv ZigBee. Piv nrog rau lwm cov kev xaiv, Wi-Fi kuj yog lub zog tshaib plab, yog li ntawd yuav muaj teeb meem yog tias koj tswj lub roj teeb khiav ntse, tab sis tsis muaj teeb meem yog tias lub cuab yeej ntse txuas rau hauv tsev tam sim no.

BLUTOOTH

BLE (bluetooth) kev siv hluav taws xob tsawg yog sib npaug rau nruab nrab ntawm WiFi nrog Zigbee, ob leeg muaj Zigbee qis zog (lub zog noj qis dua cov WiFi), cov yam ntxwv ntawm cov lus teb ceev ceev, thiab muaj qhov zoo ntawm kev siv yooj yim WiFi (tsis muaj. Lub rooj vag tuaj yeem txuas nrog cov xov tooj ntawm tes), tshwj xeeb tshaj yog ntawm kev siv xov tooj ntawm tes, tam sim no kuj zoo li WiFi, bluetooth raws tu qauv dhau los ua tus qauv raws tu qauv hauv lub xov tooj ntse.

Nws yog feem ntau siv rau taw tes rau taw tes kev sib txuas lus, txawm hais tias Bluetooth tes hauj lwm yuav tsim tau yooj yim heev. Cov ntawv thov uas peb txhua tus paub nrog tso cai hloov cov ntaub ntawv los ntawm cov xov tooj ntawm tes mus rau PCs. Bluetooth wireless yog qhov kev daws teeb meem zoo tshaj plaws rau cov taw tes rau taw tes txuas, vim nws muaj cov ntaub ntawv hloov pauv siab thiab, nrog rau cov kav hlau txais xov zoo, ntev ntev txog li 1KM hauv qhov xwm txheej zoo. Qhov txiaj ntsig zoo ntawm no yog kev lag luam, vim tsis muaj kev sib cais routers lossis network xav tau.

Ib qho tsis zoo yog tias Bluetooth, ntawm nws lub siab, yog tsim los rau kev sib txuas lus nyob ze, yog li koj tsuas tuaj yeem cuam tshuam rau kev tswj cov cuab yeej ntse los ntawm qhov sib ze. Lwm qhov yog tias, txawm tias Bluetooth tau nyob ib puag ncig rau ntau dua 20 xyoo, nws yog tus tshiab nkag rau hauv lub tsev ntse, thiab tseem, tsis muaj ntau lub tuam txhab tau flocked rau tus qauv.

ZIGEE

Yuav ua li cas yog ZigBee wireless? Qhov no yog cov txheej txheem wireless uas tseem ua haujlwm hauv 2.4GHz band, zoo li WiFi thiab Bluetooth, tab sis nws ua haujlwm ntawm cov ntaub ntawv qis dua. Lub ntsiab zoo ntawm ZigBee wireless yog

• Kev siv hluav taws xob tsawg
• Network muaj zog heev
• Mus txog 65,645 nodes
• Yooj yim heev los ntxiv lossis tshem cov nodes ntawm lub network

Zigbee raws li kev sib txuas lus luv luv wireless raws tu qauv, kev siv hluav taws xob tsawg, qhov zoo tshaj plaws yog tuaj yeem tsim cov khoom siv network, cov ntaub ntawv xa tawm ntawm ntau yam khoom siv ncaj qha, tab sis xav tau ib qho chaw hauv AD hoc network node los tswj Zigbee network, uas txhais tau tias hauv Zigbee cov khoom siv hauv lub network yuav tsum muaj qhov zoo ib yam li "router" cov khoom, txuas lub cuab yeej ua ke, paub txog qhov sib txuas ntawm Zigbee li.

Qhov no ntxiv "router" tivthaiv yog qhov peb hu ua lub rooj vag.

Ntxiv rau qhov zoo, ZigBee kuj muaj ntau qhov tsis zoo. Rau cov neeg siv, tseem muaj ZigBee qhov pib teeb tsa, vim tias feem ntau ZigBee cov khoom siv tsis muaj lawv tus kheej lub rooj vag, yog li ib qho ZigBee ntaus ntawv yeej tsis tuaj yeem tswj tau ncaj qha los ntawm peb lub xov tooj ntawm tes, thiab lub rooj vag yog xav tau los ntawm kev sib txuas ntawm lub hub. ntaus ntawv thiab lub xov tooj ntawm tes.

Yuav ua li cas thiaj yuav khoom siv hauv tsev ntse raws li kev pom zoo?

Feem ntau, cov hauv paus ntsiab lus ntawm kev xaiv cov cuab yeej ntse yog raws li hauv qab no:

1) Rau cov khoom siv ntsaws, siv WIFI raws tu qauv;

2) Yog tias koj xav tau kev cuam tshuam nrog lub xov tooj ntawm tes, siv BLE raws tu qauv;

3) ZigBee yog siv rau sensors.

Txawm li cas los xij, vim muaj ntau qhov laj thawj, kev cog lus sib txawv ntawm cov cuab yeej raug muag tib lub sijhawm thaum cov chaw tsim khoom hloov kho cov cuab yeej, yog li peb yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no thaum yuav cov khoom siv hauv tsev ntse:

1. Thaum yuav khoom "ZigBee” ntaus ntawv, xyuas kom tseeb tias koj muajZigBee rooj vagnyob hauv tsev, txwv tsis pub feem ntau ib leeg ZigBee li tsis tuaj yeem tswj tau ncaj qha los ntawm koj lub xov tooj ntawm tes.

2.WiFi / BLE cov khoom siv, feem ntau ntawm cov khoom siv WiFi / BLE tuaj yeem txuas ncaj qha rau lub xov tooj ntawm tes tsis muaj lub rooj vag, tsis muaj ZigBee version ntawm lub cuab yeej, yuav tsum muaj lub rooj vag txuas rau lub xov tooj ntawm tes.WiFi thiab BLE cov khoom siv yog xaiv tau.

3. Cov khoom siv BLE feem ntau yog siv los cuam tshuam nrog cov xov tooj ntawm tes ntawm qhov ze, thiab cov teeb liab tsis zoo tom qab phab ntsa. Yog li, nws tsis pom zoo kom yuav "tsuas yog" BLE raws tu qauv rau cov khoom siv uas xav tau kev tswj chaw taws teeb.

4. Yog hais tias lub tsev router tsuas yog ib lub tsev router nkaus xwb, nws tsis pom zoo tias cov khoom siv hauv tsev ntse txais yuav WIFI raws tu qauv hauv ntau, vim tias nws zoo li lub cuab yeej yuav ib txwm offline. , nkag mus rau ntau yam khoom siv WIFI yuav cuam tshuam rau kev sib txuas ib txwm ntawm WIFI.)
