wM-Bus vs LoRaWAN: Kusankha Njira Yoyenera Yopanda Waya ya Smart Metering

Kodi WMBus ndi chiyani?
WMBus, kapena Wireless M-Bus, ndi njira yolumikizirana opanda zingwe yokhazikika pansi pa EN 13757, yopangidwa kuti iziwerengera zokha komanso zakutali.

mita zothandiza. Idapangidwa koyambirira ku Europe, tsopano imagwiritsidwa ntchito kwambiri potumiza ma metering anzeru padziko lonse lapansi.

Kugwira ntchito makamaka mu gulu la 868 MHz ISM, WMBus imakongoletsedwa:

Kugwiritsa ntchito mphamvu zochepa

Kuyankhulana kwapakati

Kudalirika kwakukulu m'malo odzaza kwambiri atawuni

Kugwirizana ndi zida zoyendetsedwa ndi batri

Zofunika Kwambiri pa Wireless M-Bus
Kugwiritsa Ntchito Mphamvu Zochepa Kwambiri
Zipangizo za WMBus zimapangidwira kuti zizigwira ntchito kwa zaka 10-15 pa batri imodzi, zomwe zimawapangitsa kukhala abwino kwa kutumizidwa kwakukulu, kopanda kukonza.

Kulankhulana kotetezeka komanso kodalirika
WMBus imathandizira kubisa kwa AES-128 ndi kuzindikira zolakwika za CRC, kuwonetsetsa kufalitsa kotetezedwa komanso kolondola kwa data.

Multiple Operation Modes
WMBus imapereka mitundu ingapo yothandizira mapulogalamu osiyanasiyana:

S-Mode (Stationary): Zokhazikika zokhazikika

T-Mode (Kutumiza): Kuwerenga kwa mafoni kudzera pakuyenda kapena kuyendetsa

C-Mode (Yophatikizana): Kukula kochepa kotumiza kwamphamvu kwamphamvu

Miyezo-Yotengera Kugwirizana
WMBus imathandizira kutumizidwa kwa ogulitsa-osalowerera ndale-zida zochokera kwa opanga osiyanasiyana zimatha kulankhulana momasuka.

Kodi WMBus Imagwira Ntchito Motani?
Mamita opangidwa ndi WMBus amatumiza mapaketi a data osungidwa pakanthawi kokonzekera kwa wolandila—kaya yam'manja (yotolera poyendetsa) kapena yokhazikika (kudzera pachipata kapena cholumikizira). Mapaketi awa nthawi zambiri amakhala:

Zomwe zimagwiritsidwa ntchito

Mulingo wa batri

Tamper status

Zizindikiro zolakwika

Deta yosonkhanitsidwayo imatumizidwa ku kasamalidwe ka data pakati kuti azilipira, kusanthula, ndi kuyang'anira.

Kodi WMBus Imagwiritsidwa Ntchito Kuti?
WMBus ndi ambiri anatengera ku Ulaya kwa nzeru zofunikira metering. Zomwe zimagwiritsidwa ntchito ndizo:

Mamita amadzi anzeru m'makina a municipalities

Mamita a gasi ndi kutentha kwa ma network otenthetsera chigawo

Mamita amagetsi m'nyumba zogona komanso zamalonda

WMBus nthawi zambiri imasankhidwira madera akumatauni omwe ali ndi zomangamanga zomwe zilipo kale, pomwe LoRaWAN ndi NB-IoT zitha kukondedwa kumadera obiriwira kapena kumidzi.

Ubwino Wogwiritsa Ntchito WMBus
Mphamvu ya Battery: Kutalika kwa chipangizo nthawi yayitali

Chitetezo cha Data: Thandizo la AES encryption

Kuphatikizika Kosavuta: Kulumikizana kokhazikika kokhazikika

Flexible Deployment: Imagwira ntchito pamanetiweki am'manja komanso osasunthika

TCO Yotsika: Yotsika mtengo poyerekeza ndi mayankho otengera ma cellular

Kusintha ndi Msika: WMBus + LoRaWAN Dual-Mode
Opanga mita ambiri tsopano amapereka ma module a WMBus + LoRaWAN amitundu iwiri, kulola kugwira ntchito mosasunthika pama protocol onse awiri.

Njira ya hybrid iyi imapereka:

Kugwirizana pakati pa maukonde

Njira zosinthira zosamuka kuchokera ku WMBus kupita ku LoRaWAN

Kufalikira kokulirapo kokhala ndi kusintha kochepa kwa zida

Tsogolo la WMBus
Pamene njira zoyendetsera mzinda wanzeru zikukulirakulira komanso malamulo akukhazikika pakusunga mphamvu ndi madzi, WMBus ikadali yothandizira kwambiri

kusonkhanitsa deta moyenera komanso kotetezedwa kwazinthu zofunikira.

Ndi kuphatikiza kopitilira mumayendedwe amtambo, ma analytics a AI, ndi nsanja zam'manja, WMBus ikupitilizabe kusinthika - kutseka kusiyana.

pakati pa machitidwe olowa ndi zida zamakono za IoT.
