I-wM-Bus vs LoRaWAN:Ukukhetha Iphrothokholi Elungile Engenantambo Ye-Smart Metering

Iyini i-WMBus?
I-WMBus, noma i-Wireless M-Bus, iyiphrothokholi yokuxhumana engenantambo esezingeni ngaphansi kwe-EN 13757, eyenzelwe ukufundwa okuzenzakalelayo nokukude.

amamitha wokusetshenziswa. Yathuthukiswa ekuqaleni eYurophu, manje isisetshenziswa kabanzi ekusetshenzisweni kwamamitha okuhlakaniphile emhlabeni wonke.

Isebenza ngokuyinhloko kubhendi ye-ISM engu-868 MHz, i-WMBus ithuthukiselwe:

Ukusetshenziswa kwamandla aphansi

Ukuxhumana kwebanga eliphakathi

Ukuthembeka okuphezulu ezindaweni eziminyene zasemadolobheni

Ukuhambisana namadivayisi asebenza ngebhethri

Izici Eziyinhloko Ze-Wireless M-Bus
Ukusetshenziswa kwamandla Aphansi Kakhulu
Amadivayisi e-WMBus aklanyelwe ukusebenza iminyaka engu-10–15 ebhethrini elilodwa, okuwenza afanelekele ukuthunyelwa kwenani elikhulu, okungenakulungiswa.

Ukuxhumana Okuvikelekile Nokwethenjelwa
I-WMBus isekela ukubethela kwe-AES-128 kanye nokutholwa kwamaphutha e-CRC, iqinisekisa ukudluliswa kwedatha okuphephile nokunembile.

Izindlela Zokusebenza Eziningi
I-WMBus inikeza izindlela ezimbalwa zokusekela izinhlelo zokusebenza ezihlukahlukene:

I-S-Mode (Emile): Ingqalasizinda elungisiwe

I-T-Mode (Dlulisa): Ukufundwa kweselula ngokuhamba ngezinyawo noma ngokushayela

I-C-Mode (Ihlangene): Usayizi omncane wokudlulisela wokonga kwamandla

Ukusebenzisana Okusekelwe Emazingeni
I-WMBus inika amandla ukuthunyelwa okungathathi hlangothi komthengisi—amadivayisi avela kubakhiqizi abahlukene angakwazi ukuxhumana ngaphandle komthungo.

Isebenza kanjani i-WMBus?
Amamitha anikwe amandla i-WMBus athumela amaphakethe edatha afakwe ikhodi ngezikhathi ezithile kowamukelayo—kungaba iselula (ngokuqoqwa kokushayela) noma engaguquki (ngesango noma isixhumi esigxilisa ingqondo). Lawa maphakethe ngokuvamile ahlanganisa:

Idatha yokusetshenziswa

Izinga lebhethri

Isimo sokuphazamisa

Amakhodi ephutha

Idatha eqoqiwe ibe isidluliselwa ohlelweni lokuphatha idatha olumaphakathi ukuze kukhokhiswe, kuhlaziywe, futhi kuqashwe.

Isetshenziswa kuphi i-WMBus?
I-WMBus yamukelwa kabanzi eYurophu nge-smart Utility metering. Izimo ezijwayelekile zokusetshenziswa zihlanganisa:

Amamitha amanzi ahlakaniphile ezinhlelweni zikamasipala

Igesi kanye namamitha okushisa amanethiwekhi okushisa esifunda

Amamitha kagesi ezakhiweni zokuhlala nezohwebo

I-WMBus ivamise ukukhethwa ezindaweni zasemadolobheni ezinengqalasizinda yokulinganisa ekhona, kuyilapho i-LoRaWAN ne-NB-IoT ingase ikhethwe endaweni eluhlaza noma ezindaweni zasemakhaya.

Izinzuzo Zokusebenzisa i-WMBus
Ukusebenza Kwebhethri: Isikhathi eside sedivayisi

Ukuphepha Kwedatha: Ukusekelwa kokubethela kwe-AES

Ukuhlanganisa Okulula: Ukuxhumana okuvulekile okusekelwe ezingeni

Ukuthunyelwa Okuvumelana Nezimo: Isebenza kuwo womabili amanethiwekhi eselula namanethiwekhi angashintshi

I-TCO Ephansi: Ibiza izindleko uma iqhathaniswa nezixazululo ezisekelwe kumaselula

Ukuvela ngeMakethe: I-WMBus + LoRaWAN-Dual-Mode
Abakhiqizi abaningi bamamitha manje banikeza amamojula e-WMBus + LoRaWAN anemodi ekabili, avumela ukusebenza okungenamthungo kuzo zombili izivumelwano.

Le ndlela ye-hybrid inikeza:

Ukusebenzisana kuwo wonke amanethiwekhi

Izindlela zokufuduka eziguquguqukayo ukusuka ku-WMBus yefa kuya ku-LoRaWAN

Ukutholakala okubanzi kwendawo enezinguquko ezincane zehadiwe

Ikusasa le-WMBus
Njengoba izinhlelo zedolobha elihlakaniphile zikhula futhi nemithethonqubo iqinisa ukongiwa kwamandla kanye namanzi, i-WMBus isalokhu ingumthombo oyinhloko wo

ukuqoqwa kwedatha okusebenzayo nokuvikelekile kwezinsiza.

Ngokuhlanganiswa okuqhubekayo ezinhlelweni zamafu, izibalo ze-AI, namapulatifomu eselula, i-WMBus iyaqhubeka nokuvela-ukuvala igebe.

phakathi kwezinhlelo zefa nengqalasizinda yesimanje ye-IoT.
