NB-IoT ultrasonic dej ntsuas ncaj qha uploads cov ntaub ntawv mus rau lub meter nyeem tus tswv chaw nres tsheb los ntawm tus neeg teb xov tooj network, tsis muaj kev txhim kho lub concentrator. Cov zaus band tso cai los ntawm tus neeg teb xov tooj yog siv, thiab muaj qhov cuam tshuam tsawg heev, uas ua kom muaj kev ruaj ntseg ntawm kev sib txuas lus.
Nta ntawm NB-IOT Ultrasonic Dej Meter
◇ Muaj zog txuas
Nyob rau hauv cov ntaub ntawv ntawm tib lub hauv paus chaw nres tsheb, lub sij hawm nkag mus ntawm ultrasonic dej ntsuas nrog NB-IoT wireless kis tau tus mob muaj nuj nqi yog nce los ntawm 50-100 zaug piv nrog ultrasonic dej ntsuas siv lwm yam wireless technologies uas twb muaj lawm. Nws tuaj yeem txhawb nqa 100,000 kev sib txuas thiab tuaj yeem ua tiav qhov tsis tshua muaj latency rhiab heev, cov khoom siv qis qis, cov cuab yeej siv hluav taws xob tsawg, thiab kev ua haujlwm zoo hauv network.
◇ Kev pab dav dav
NB-IoT muaj qhov muaj peev xwm tiv thaiv sab hauv tsev, yog li NB-IOT ultrasonic dej ntsuas tsis tuaj yeem tsuas yog ua tau raws li qhov xav tau ntawm kev siv dav hauv cov neeg nyob deb nroog tab sis kuj tseem siv tau rau cov chaw uas xav tau kev pabcuam sib sib zog nqus, xws li cov chaw tsim khoom, chaw nres tsheb hauv av, npog manhole, thiab lwm yam.
◇ Kev siv hluav taws xob tsawg
Kev siv hluav taws xob tsawg yog qhov taw qhia tseem ceeb rau kev siv IoT, tshwj xeeb tshaj yog rau qee cov khoom siv thiab lub sijhawm uas tsis tuaj yeem hloov cov roj teeb ntau zaus. NB-IoT ultrasonic dej ntsuas tsom rau cov ntaub ntawv me me thiab kev siv qis qis, yog li kev siv hluav taws xob ntawm NB-IoT ultrasonic dej ntsuas tau me me, thiab lub roj teeb lub neej ntawm lub cuab yeej kuj zoo heev.

NB-IoT Ultrasonic Water Meter Application Scenarios
1. Cov vaj tsev tshiab, cov tsev qub, kev kho dua tshiab ntawm cov tsev qub, thiab lwm qhov chaw uas yuav tsum tau hloov qhov chaw ntsuas qhov qub
Qhov zoo:
a. Thawj qhov chaw yog ntsia rau ntawm lub rooj thiab tsis tas yuav muaj lwm yam kev hloov dej thiab kev tsim kho.
b. Koj tsuas tuaj yeem hloov lub rooj tsis zoo, thiab koj tuaj yeem hloov cov ntaub ntawv tsis tas yuav tsum tau hloov tag nrho cov ntxhuav.
2. Qhov chaw nyob tshiab tsim nyob rau hauv kev tswj hwm tus kheej ntawm cov cuab yeej yuav tsum tau tshaj tawm ib puag ncig nrog tus lej ntawm cov khoom siv uas tau tawg.
Qhov zoo:
a. Tsuas yog daim ntawv tshaj tawm raug teeb tsa, thiab tag nrho cov meters tsis tas yuav tsum tau nruab thiab debugged ua ntej. Nruab ib lub moos thiab upload cov ntaub ntawv ntawm lub moos.
b. Nws tuaj yeem paub cov haujlwm uas yooj yim rau kev tswj hwm, xws li kev them nyiaj ua ntej.
3. Ib puag ncig nrog kev ncua deb ntawm epitopes xws li villa cheeb tsam
Qhov zoo:
a. Kev txhim kho lub rooj nyob rau hauv thawj lub rooj txoj hauj lwm tsis tas yuav tsum tau siv ntau dhau thiab kev xaim.
b. Lub 'meter' muaj nws tus kheej kev ua haujlwm upload, thiab tsis tas yuav nruab ib qho khoom siv ntxiv kom paub meej cov teeb liab kis tau tus mob.
4. Lwm qhov chaw
Qhov zoo:
Ntev npaum li lwm txoj kev sib txuas lus tuaj yeem ua tau raws li ib puag ncig, Internet of Things meter tuaj yeem ntsia tau rau hauv qhov chaw ntsuas qhov qub thaum lub teeb liab tus nqi txaus siab, thiab tsis tas yuav nruab ib qho khoom siv ntxiv.
