Mesh yog dab tsi?
Mesh Network yog cov qauv topology rau kev sib txuas lus. Ntawm Mesh network, cov ntaub ntawv tuaj yeem xa los ntawm ib qho ntawm txhua lub network, thiab thaum ib qho ntawm cov nodes hauv lub network tsis ua haujlwm, tag nrho lub network tseem tuaj yeem tswj hwm kev sib txuas lus ib txwm, nws muaj qhov zoo ntawm kev sib txuas lus yooj yim thiab muaj peev xwm tiv thaiv kev cuam tshuam. .
BLE Bluetooth yog dab tsi Mesh?
Bluetooth v5.0 ntxiv BLE ib feem. Piv nrog rau cov tsoos bluetooth, ble mesh network muaj peev xwm npog ntev thiab tsis muaj kev sib txuas ntawm cov nodes, kuj daws qhov teeb meem luv luv Bluetooth txuas, tam sim no nws dhau los ua qhov tseem ceeb rau IOT.
BLE Mesh yog suav nrog Txawb thiab Node. Mobile txhais tau tias smartphone. Smartphone ua tus tswj sab ntawm mesh network. Node yog node ntaus ntawv hauv lub network. BLE Mesh network muaj nuj nqi yog ua tiav los ntawm txoj kev tshaj tawm. Cov kauj ruam yooj yim yog raws li nram no:
- Tshaj tawm cov ntaub ntawv los ntawm node A;
- Node B tshaj tawm cov ntaub ntawv los ntawm node A tom qab tau txais cov ntaub ntawv los ntawm node A.
- Thiab yog li ntawd, los ntawm txoj kev kis tus kab mob, ib qho dhau kaum, kaum kis, kom txhua yam khoom siv wireless tau txais cov ntaub ntawv no.
Siv txoj hauv kev no ua ke nrog peb cov kev txawj ntse routing algorithms tuaj yeem xa cov lus zoo thoob plaws hauv lub network thiab txo cov kev cuam tshuam tsis zoo ntawm kev tshaj tawm cua daj cua dub thiab spam. Thiab BLE Mesh tseem encrypts cov ntaub ntawv hauv lub network los tiv thaiv nws los ntawm cov ntaub ntawv network nyiag los ntawm kev saib xyuas thiab kev tawm tsam ntawm tus txiv neej-hauv nruab nrab.
Tsim kom muaj teeb pom kev zoo nrog BLE Mesh. Cov kab ke no muaj ob hom khoom siv xws li hloov pauv thiab lub teeb ntse, smartphone ua qhov kawg ntawm lub network. Ua ntej, lub teeb ntse thiab cov hloov pauv tau muab faib rau hauv ob chav, tom qab ntawd muab lawv tso rau hauv ib lub vas los ntawm lub xov tooj ntse, thiab muab faib ua pawg raws li chav tsev. Xws li BLE Mesh network tau ua tiav, tsis tas yuav ntxiv cov khoom siv routing. Ob lub teeb ntse no tuaj yeem tswj tau ncaj qha los ntawm kev hloov. Cov txheej txheem tswj no tsis tas yuav muaj kev koom tes ntawm lub smartphone. Kev pab pawg yog dawb heev, koj tuaj yeem sib xyaw cov teeb ntse ntse thiab hloov pauv raws li koj tus kheej nyiam. Smartphone kuj tseem tuaj yeem hloov kho lub teeb ntse tau yooj yim. Raws li tus naj npawb ntawm cov teeb pom kev ntse hauv lub network nce, thaj chaw uas muaj los ntawm lub network kuj nce ntxiv.
Qhov no tsuas yog qhov pib, txuas nrog lub BLE Mesh network, nws tuaj yeem ntxiv ntau lub zog qis thiab cov khoom siv ntse rau lub network. Tom qab ntawd pab pawg lawv los ntawm smartphone thiab pab kom lawv ua haujlwm ua ke. Txhua yam yuav ntse dua.
ZigBee Mesh network muaj xws li Coordinator(C), Router(R) thiab End Device(D). Tag nrho lub network yog tswj los ntawm C, C tuaj yeem txuas ncaj qha rau D, tab sis yog tias D thiab C yog dhau qhov siab tshaj plaws, nws yuav tsum txuas nrog R hauv nruab nrab. Nws tsis tuaj yeem sib txuas lus ntawm D thiab D, tab sis tuaj yeem nce R kom txuas tau lub network.
Qhov zoo ntawm BLE Bluetooth ntxaij
BLE Mesh network yog qhov yooj yim dua, lub network tsuas yog tsim los ntawm cov khoom siv, thiab tsis xav tau kev koom tes ntawm router. Sab tswj siv lub xov tooj ntse, Thaum muab kev yooj yim rau cov neeg siv, nws kuj txuag tau tus nqi tsim lub network. Vim tias qhov txuas ntxiv ntawm lub network tsis xav tau router koom nrog, lub network kuj yooj yim dua rau kev xa tawm.
Ntxiv rau qhov muaj txiaj ntsig zoo, niaj hnub no, cov xov tooj ntse, ntsiav tshuaj thiab khoos phis tawj tau nruab nrog Bluetooth, cov neeg siv txuas mus rau BLE Mesh network ntawm Bluetooth, kom tsis txhob ncua sijhawm thiab tuag tes tuag taw los ntawm lub network, tab sis kuj tsis tas yuav teeb tsa lub rooj vag nyuaj. Txhim kho cov neeg siv kev paub zoo heev.
Summary rau hauv cov ntsiab lus hauv qab no:
- Network qauv yog yooj yim, yooj yim rau deploy.
- tsis xav tau cov khoom siv routing thiab coordinator, tus nqi qis dua.
- Nkag mus los ntawm Bluetooth, zam lub network qeeb.
- Tshem tawm cov teeb meem ntawm kev teeb tsa lub rooj vag rau cov neeg siv uas tsis xav tau ntau yam kev sib txuas lus
- Smartphones tau nruab nrog Bluetooth, yooj yim rau kev txhawb nqa.
