wM-Bus vs LoRaWAN: Guhitamo Porotokoro iboneye yo gupima ubwenge

WMBus ni iki?
WMBus, cyangwa Wireless M-Bus, ni protocole y'itumanaho idafite insinga isanzwe munsi ya EN 13757, yagenewe gusoma mu buryo bwikora kandi bwa kure bwa

metero zingirakamaro. Ubusanzwe byatejwe imbere muburayi, ubu birakoreshwa cyane mubikorwa byo gupima ubwenge.

Gukora cyane cyane muri 868 MHz ISM band, WMBus itezimbere kuri:

Gukoresha ingufu nke

Itumanaho rito

Kwizerwa kwinshi mubidukikije byuzuye mumijyi

Guhuza nibikoresho bikoreshwa na bateri

Ibyingenzi byingenzi bya Wireless M-Bus
Gukoresha ingufu zidasanzwe
Ibikoresho bya WMBus byashizweho kugirango bikore imyaka 10-15 kuri bateri imwe, bituma biba byiza kubikorwa binini, bitarimo kubungabunga.

Itumanaho ryizewe kandi ryizewe
WMBus ishyigikira ibanga rya AES-128 hamwe no kumenya amakosa ya CRC, itanga amakuru yizewe kandi yuzuye.

Uburyo bwinshi bwo gukora
WMBus itanga uburyo bwinshi bwo gushyigikira porogaramu zitandukanye:

S-Mode (Ahagarara): Ibikorwa remezo bihamye

T-Mode (Kohereza): Gusoma kuri terefone ukoresheje kugenda cyangwa gutwara

C-Mode (Ihuzagurika): Ingano ntoya yo gukwirakwiza ingufu

Ibipimo-bishingiye ku mikoranire
WMBus ituma abadandaza batagira aho babogamiye - ibikoresho biva mubakora bitandukanye birashobora kuvugana nta nkomyi.

Nigute WMBus ikora?
Imetero ikoreshwa na WMBus yohereje paki zamakuru zipakiye mugihe cyagenwe kubakira - haba mobile (kubikusanyamakuru) cyangwa byagenwe (binyuze mumarembo cyangwa intumbero). Izi paki zirimo:

Amakuru yo gukoresha

Urwego rwa Bateri

Imiterere

Kode y'amakosa

Ikusanyamakuru ryakusanyirijwe muri sisitemu nkuru yo gucunga amakuru yo kwishyuza, gusesengura, no gukurikirana.

WMBus ikoreshwa he?
WMBus ikoreshwa cyane muburayi kugirango ibe ifite ubwenge bwingirakamaro. Imanza zisanzwe zikoreshwa zirimo:

Imetero y'amazi meza muri sisitemu ya komine

Imashini ya gazi nubushyuhe bwo guhuza uturere

Imashanyarazi muri nyubako zo guturamo nubucuruzi

WMBus ikunze gutoranywa mumijyi ifite ibikorwa remezo byo gupima bihari, mugihe LoRaWAN na NB-IoT birashobora gukundwa mumashanyarazi cyangwa icyaro.

Inyungu zo Gukoresha WMBus
Gukoresha Bateri: Ibikoresho birebire igihe cyose

Umutekano wamakuru: Inkunga ya AES

Kwishyira hamwe byoroshye: Fungura itumanaho rishingiye ku itumanaho

Ihinduka ryoroshye: Ikora kuri terefone igendanwa kandi ihamye

TCO yo hepfo: Igiciro-cyiza ugereranije na selile ishingiye kubisubizo

Guhindagurika hamwe nisoko: WMBus + LoRaWAN Dual-Mode
Abakora metero nyinshi ubu batanga uburyo bubiri bwa WMBus + LoRaWAN, butuma imikorere idahwitse muri protocole zombi.

Ubu buryo bwa Hybrid butanga:

Imikoranire hagati y'urusobe

Inzira zoroshye zo kwimuka kuva mumurage WMBus kugera LoRaWAN

Kwagura geografiya yagutse hamwe nibikoresho bike byahinduwe

Kazoza ka WMBus
Mugihe ibikorwa byumugi byubwenge bigenda byiyongera kandi amabwiriza agakomeza ingufu no kubungabunga amazi, WMBus ikomeje kuba ingenzi

ikusanyamakuru ryiza kandi ryizewe kubikorwa byingirakamaro.

Hamwe nogukomeza kwinjizwa muri sisitemu yibicu, isesengura rya AI, hamwe na porogaramu igendanwa, WMBus ikomeje gutera imbere - ikuraho icyuho

hagati ya sisitemu yumurage nibikorwa remezo bigezweho bya IoT.
