I-wM-Bus vs LoRaWAN: Ukukhetha iProtokholi eLungileyo engenangcingo yokuBatha ngemitha nge-Smart

Yintoni iWMBus?
I-WMBus, okanye i-Wireless M-Bus, yiprothokholi yonxibelelwano engenazingcingo ekumgangatho ophantsi kwe-EN 13757, eyilelwe ufundo oluzenzekelayo nolukude.

iimitha zoncedo. Iphuhliswe okokuqala eYurophu, ngoku isetyenziswa ngokubanzi kwi-smart metering deployments kwihlabathi jikelele.

Isebenza ikakhulu kwi-868 MHz ISM band, i-WMBus yenzelwe:

Ukusetyenziswa kwamandla aphantsi

Unxibelelwano oluphakathi

Ukuthembeka okuphezulu kwiindawo ezixineneyo zasedolophini

Ukuhambelana nezixhobo ezisebenza ngebhetri

Iimpawu eziphambili ze-M-Bus engenazingcingo
Ukusetyenziswa kwamandla aphantsi kakhulu
Izixhobo ze-WMBus zenzelwe ukuba ziqhube iminyaka eyi-10-15 kwibhetri enye, zizenza zigqibelele kwizinga elikhulu, ukuthunyelwa okungenalo ukugcinwa.

Unxibelelwano olukhuselekileyo noluthembekileyo
I-WMBus ixhasa ukubethelwa kwe-AES-128 kunye nokufunyanwa kwempazamo ye-CRC, iqinisekisa ukuhanjiswa kwedatha ekhuselekileyo nechanekileyo.

Iindlela zokuSebenza ezininzi
I-WMBus ibonelela ngeendlela ezininzi zokuxhasa izicelo ezahlukeneyo:

I-S-Mode (eMiyo): Iziseko zophuhliso ezizinzileyo

I-T-Mode (Ukudlulisa): Ukufundwa kweselula ngokuhamba nge-walk by or drive-by

I-C-Mode (I-Compact): Ubungakanani obuncinci bothumelo bokusebenza kakuhle kwamandla

Ukusebenzisana okuSekwe kwiMigangatho
I-WMBus yenza ukuba umthengisi-ongathathi hlangothi-izixhobo ezivela kubavelisi abahlukeneyo ziyakwazi ukunxibelelana ngokukhululekileyo.

Isebenza njani iWMBus?
Iimitha ze-WMBus-enabled zithumela iipakethi zedatha ezikhowudiweyo ngamaxesha acwangcisiweyo kumamkeli-mhlawumbi iselula (yokuqokelela i-drive-by) okanye ilungisiwe (ngesango okanye i-concentrator). Ezi pakethi zibandakanya:

Idatha yokusetyenziswa

Inqanaba lebhetri

Ubume bokuphazamisa

Iikhowudi zeempazamo

Idatha eqokelelweyo igqithiselwa kwisistim yolawulo lwedatha esembindini ukuze kuhlawuliswe, kuhlalutywe kwaye kubekwe iliso.

Isetyenziswa phi iWMBus?
I-WMBus yamkelwa ngokubanzi eYurophu kwimitha yombane oluncedo. Iimeko zokusetyenziswa eziqhelekileyo ziquka:

Iimitha zamanzi ezihlakaniphile kwiinkqubo zikamasipala

Imitha yegesi kunye nobushushu kuthungelwano lokufudumala lwesithili

Iimitha zombane kwizakhiwo zokuhlala kunye nezorhwebo

I-WMBus ihlala ikhethwa kwiindawo zasezidolophini ezineziseko zokulinganisa iimitha ezikhoyo, ngelixa i-LoRaWAN kunye ne-NB-IoT inokukhethwa kwindawo eluhlaza okanye kwiindawo ezisemaphandleni.

Iinzuzo zokusebenzisa i-WMBus
Ukusebenza kwebhetri: Ixesha elide lesixhobo

Ukhuseleko lweDatha: Inkxaso yofihlo lwe-AES

Ukudityaniswa lula: Vula unxibelelwano olusekwe emgangathweni

I-Flexible Deployment: Isebenza kuzo zombini iinethiwekhi eziphathwayo kunye nezisisigxina

I-TCO ephantsi: Ixabiso eliphantsi xa kuthelekiswa nezisombululo ezisekelwe kwiselula

Ukuvela kunye neMarike: I-WMBus + i-LoRaWAN ye-Dual-Mode
Uninzi lwabavelisi beemitha ngoku banikezela ngeemodyuli ze-WMBus + LoRaWAN ezimbini, ezivumela ukusebenza ngokungenamthungo kuzo zombini iiprotocol.

Le ndlela yokuxuba ibonelela:

Ukusebenzisana kuwo wonke uthungelwano

Iindlela zokufuduka eziguquguqukayo ukusuka kwi-WMBus yelifa ukuya kwi-LoRaWAN

Ijografi ebanzi kunye neenguqu ezincinci zehardware

Ikamva leWMBus
Njengoko amalinge esixeko esilumkileyo esanda kwaye nemithetho iqinisa malunga nokugcinwa kwamandla kunye nokugcinwa kwamanzi, i-WMBus ihlala ingundoqo

ingqokelela yedatha esebenzayo nekhuselekileyo yezixhobo eziluncedo.

Ngokudityaniswa okuqhubekayo kwiinkqubo zefu, i-AI analytics, kunye neeplatifti zeselula, i-WMBus iyaqhubeka nokuguquka-ukuvala i-gap.

phakathi kweenkqubo zelifa kunye neziseko ze-IoT zanamhlanje.
