Niaj hnub nim no kev siv tshuab hauv tsev yog qhov nrov heev. Muaj ntau yam wireless protocols sib txawv, tab sis cov uas feem ntau cov neeg tau hnov ​​​​​​txog yog WiFi thiab Bluetooth vim tias cov no siv rau hauv cov khoom siv uas peb ntau tus muaj, xov tooj ntawm tes thiab khoos phis tawj. Tab sis muaj lwm txoj hauv kev thib peb hu ua ZigBee uas tsim los rau kev tswj hwm thiab kev ntsuas. Ib yam uas peb muaj sib xws yog tias lawv ua haujlwm ntawm tib lub zaus - ntawm lossis txog 2.4 GHz. Qhov zoo sib xws xaus rau ntawd. Yog li qhov txawv yog dab tsi?

WIFI

WiFi yog ib qho hloov pauv ncaj qha rau cov xov hlau Ethernet thiab siv rau tib qho xwm txheej kom tsis txhob muaj xov hlau khiav txhua qhov chaw. Qhov zoo ntawm WiFi yog tias koj yuav muaj peev xwm tswj thiab saib xyuas koj lub tsev cov khoom siv ntse los ntawm txhua qhov chaw hauv ntiaj teb los ntawm xov tooj ntse, ntsiav tshuaj, lossis laptop. Thiab, vim yog Wi-Fi qhov nyob txhua qhov chaw, muaj ntau yam khoom siv ntse uas ua raws li tus qauv no. Nws txhais tau tias lub PC tsis tas yuav tsum tso tseg kom nkag mus rau lub cuab yeej siv WiFi. Cov khoom siv nkag mus deb xws li lub koob yees duab IP siv WiFi yog li lawv tuaj yeem txuas nrog lub router thiab nkag mus thoob plaws hauv 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.

Qhov tsis zoo yog tias cov khoom siv ntse uas tswj los ntawm Wi-Fi feem ntau kim dua li cov uas ua haujlwm hauv ZigBee. Piv rau lwm cov kev xaiv, Wi-Fi siv hluav taws xob ntau, yog li ntawd yuav yog teeb meem yog tias koj tswj cov khoom siv ntse uas siv roj teeb, tab sis tsis muaj teeb meem dab tsi yog tias cov khoom siv ntse raug txuas rau hauv tsev tam sim no.

BLUTOOTH

BLE (bluetooth) siv hluav taws xob tsawg sib npaug rau nruab nrab ntawm WiFi nrog Zigbee, ob qho tib si muaj Zigbee siv hluav taws xob tsawg (kev siv hluav taws xob qis dua li WiFi), cov yam ntxwv ntawm kev teb sai, thiab muaj qhov zoo ntawm kev siv WiFi yooj yim (tsis muaj lub rooj vag tuaj yeem txuas nrog cov tes hauj lwm mobile), tshwj xeeb tshaj yog rau kev siv xov tooj ntawm tes, tam sim no zoo li WiFi, bluetooth protocol dhau los ua tus qauv protocol hauv lub xov tooj ntse.

Feem ntau nws yog siv rau kev sib txuas lus taw tes rau taw tes, txawm hais tias Bluetooth networks tuaj yeem tsim tau yooj yim heev. Cov ntawv thov ib txwm peb txhua tus paub txog kev tso cai rau kev xa cov ntaub ntawv los ntawm xov tooj ntawm tes mus rau PCs. Bluetooth wireless yog qhov kev daws teeb meem zoo tshaj plaws rau cov kev sib txuas taw tes rau taw tes no, vim nws muaj cov nqi xa cov ntaub ntawv siab thiab, nrog lub antenna zoo, ntev heev txog li 1KM hauv qhov xwm txheej zoo tagnrho. Qhov zoo tshaj plaws ntawm no yog kev txuag nyiaj, vim tsis tas yuav muaj cov routers lossis networks sib cais.

Ib qho tsis zoo yog tias Bluetooth, ntawm nws lub plawv, yog tsim los rau kev sib txuas lus ze, yog li koj tsuas tuaj yeem cuam tshuam kev tswj hwm ntawm lub cuab yeej ntse los ntawm qhov ze. Lwm qhov yog tias, txawm hais tias Bluetooth tau muaj nyob rau ntau tshaj 20 xyoo, nws yog tus neeg nkag tshiab rau hauv kev ua lag luam hauv tsev ntse, thiab txog tam sim no, tsis muaj ntau lub tuam txhab tsim khoom tau sib sau ua ke rau tus qauv.

ZIGBEE

Ua li cas txog ZigBee wireless? Qhov no yog ib qho wireless protocol uas kuj ua haujlwm hauv 2.4GHz band, zoo li WiFi thiab Bluetooth, tab sis nws ua haujlwm ntawm cov ntaub ntawv qis dua. Cov txiaj ntsig tseem ceeb ntawm ZigBee wireless yog

• Kev siv hluav taws xob tsawg
• Lub network muaj zog heev
• Txog li 65,645 lub nodes
• Yooj yim heev rau ntxiv lossis tshem tawm cov nodes ntawm lub network

Zigbee ua ib qho kev sib txuas lus wireless luv luv, siv hluav taws xob tsawg, qhov zoo tshaj plaws yog tias nws tuaj yeem tsim cov khoom siv network, xa cov ntaub ntawv ntawm ntau yam khoom siv txuas 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 network yuav tsum muaj cov khoom zoo ib yam li "router", txuas cov khoom siv ua ke, thiab ua tiav qhov kev sib txuas ntawm Zigbee cov khoom siv.

Qhov khoom ntxiv "router" no 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 qhov txwv rau kev teeb tsa ZigBee, vim tias feem ntau cov khoom siv ZigBee tsis muaj lawv lub rooj vag, yog li ib lub cuab yeej ZigBee yeej tsis tuaj yeem tswj hwm ncaj qha los ntawm peb lub xov tooj ntawm tes, thiab lub rooj vag yog qhov xav tau ua lub hauv paus txuas ntawm lub cuab yeej thiab lub xov tooj ntawm tes.

Yuav ua li cas thiaj yuav tau lub cuab yeej ntse hauv tsev raws li daim ntawv cog lus?

Feem ntau, cov ntsiab cai ntawm cov txheej txheem xaiv cov cuab yeej ntse yog raws li nram no:

1) Rau cov khoom siv uas tau txuas rau hauv, siv WIFI protocol;

2) Yog tias koj xav tau kev sib txuas lus nrog lub xov tooj ntawm tes, siv BLE protocol;

3) ZigBee siv rau cov sensors.

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

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

2.Cov khoom siv WiFi / BLE, feem ntau ntawm cov khoom siv WiFi / BLE tuaj yeem txuas ncaj qha rau lub xov tooj ntawm tes network yam tsis muaj lub rooj vag, tsis muaj ZigBee version ntawm lub cuab yeej, yuav tsum muaj lub rooj vag los 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 sib tham nrog cov xov tooj ntawm tes ntawm qhov ze, thiab lub teeb liab tsis zoo tom qab phab ntsa. Yog li ntawd, nws tsis pom zoo kom yuav "tsuas yog" BLE protocol rau cov khoom siv uas xav tau kev tswj chaw taws teeb.

4. Yog tias lub router hauv tsev tsuas yog lub router hauv tsev ib txwm muaj, nws tsis pom zoo kom cov khoom siv hauv tsev ntse siv WIFI protocol ntau heev, vim tias nws yuav ua rau lub cuab yeej tsis ua haujlwm tas li. (Vim yog cov nodes nkag tau tsawg ntawm cov routers ib txwm muaj, kev nkag mus rau ntau lub WIFI khoom siv yuav cuam tshuam rau kev sib txuas ib txwm ntawm WIFI.)
