Abstract
LoRaWAN dej ntsuas dej yog hom tshiab tiam tshiab ntawm wireless ntsuas dej nrog tsim zoo. Nws siv LoRaWAN kev sib txuas lus thev naus laus zis, uas tuaj yeem xa cov ntaub ntawv ruaj khov thiab ntseeg tau ntev ntev, kom paub txog kev nyeem ntawv thiab kev tswj hwm chaw taws teeb.
Nws tuaj yeem paub txog kev tswj hwm kev siv dej ntse, xws li kev them nyiaj ua ntej, nyeem cov ntsuas dej hauv thaj chaw deb, suav cov dej haus txhua hnub / hli / xyoo thiab txheeb xyuas kev ua haujlwm. Nws yog dav siv hauv tsev, tsev kawm ntawv, tsev so, tsev, factories, thiab lwm yam.
Khoom nta
1. Unlimited installation lub kaum sab xis. Koj tuaj yeem nruab LoRaWAN ntsuas dej ntawm txhua lub kaum sab xis yam tsis muaj kev cuam tshuam qhov tseeb ntawm lub ntsuas dej.
2. Lub ntsuas hluav taws xob muaj ntau txoj kev sib kis, xws li RS 485, LoRaWAN, NB-IOT
3. Ntau yam ntawm kev nyeem ntawv ntsuas: Tsawg zog LoraWAN wireless kev sib txuas lus tshuab.
4. Ntawm qhov chaw teeb tsa& kev saib xyuas yooj yim. Tsis muaj xov hlau, wireless module thiab lub hauv paus ntsuas nrog cov qauv sib cais.
5. IP68 qib waterproof: Txais kev tiv thaiv dual ntawm cov qauv sib khi thiab cov pos hniav foob.
6. Tsawg zog siv tshuab. Siv wireless ib zaug sawv& ib qho kev nyeem ntawv mechanism.
7. Lub neej ua haujlwm ntev. 6 xyoo ua haujlwm lub neej ntawm lithium roj teeb.
8. Kev sib kis ntev nyob hauv nroog. Wireless concentrator tuaj yeem thauj 1000 dej ntsuas.
9. Kev txhim kho yooj yim. Lub ntsuas ntsuas ntse txhawb cov chaw taws teeb hloov kho ua haujlwm.
10. Wireless Chirp Spread Spectrum (CSS) Technology (LoRaWAN).
