Iyi ndi mfundo yofala kwambiri yosokoneza, chifukwa mawu awiriwa nthawi zambiri amatchulidwa pamodzi koma amatanthauza zinthu zosiyana.
Njira yosavuta yofotokozera izi ndi iyi:Zigbee ndi chilankhulo, pomwe Mesh ndi njira yolankhulira.
Nayi kusanthula kwatsatanetsatane kwa kusiyana.
1. Kusiyana Kwakukulu
Zigbeendindondomeko(gulu la miyezo yolumikizirana). Limafotokoza momwe zipangizo zimadziwira zokha, momwe zimabisa deta, komanso momwe zimalumikizirana ndi netiweki. Ndi ukadaulo wapadera womwe uli ndi Connectivity Standards Alliance (CSA).
Unyolonditopology ya netiweki(kapangidwe ka kapangidwe kake). Ndi njira yolumikizira zida komwe node iliyonse imatumizira deta ya netiweki. Protocol iliyonse ingagwiritse ntchito topology ya maukonde, koma si onse omwe amachita zimenezo.
2. Kodi Zigbee ndi chiyani?
Zigbee ndi muyezo wolumikizirana opanda zingwe womwe uli ndi mphamvu zochepa komanso wocheperako, womwe umamangidwa pamwamba pa muyezo wa wailesi wa IEEE 802.15.4.
Cholinga:Yopangidwira ntchito zogwiritsa ntchito mphamvu zochepa komanso zotsika monga masensa anzeru a nyumba, mababu amagetsi, ndi maloko.
Kapangidwe ka nyumba:Zimadalira paWogwirizanitsa(hub/gateway). Mu njira zambiri zogwiritsira ntchito makasitomala (monga Philips Hue kapena Amazon Echo Plus), pali chipangizo chimodzi chachikulu chomwe chimagwira ntchito ngati "ubongo" wopanga ndikuwongolera netiweki.
Kugwirizana:Popeza ndi njira yokhazikika, chosinthira magetsi cha Zigbee kuchokera ku Kampani A chiyenera (mwachiganizo) kugwira ntchito ndi babu la magetsi la Zigbee kuchokera ku Kampani B, bola ngati ali ndi mbiri yofanana ya pulogalamuyo (monga Zigbee 3.0).
3. Kodi Mesh ndi chiyani?
Mesh imatanthauza momwe zipangizo zimalankhulirana. Mu netiweki ya mesh, chipangizo chilichonse (kapena "node") chomwe chalumikizidwa ku magetsi chingathe kugwira ntchito ngati rauta.
Momwe imagwirira ntchito:M'malo mwa chipangizo chilichonse cholumikizira mwachindunji ku rauta yapakati (monga Wi-Fi), zipangizo zimalumikizana ndi inansi yawo yapafupi. Ngati chipangizo chimodzi chalephera, netiwekiyo "imadzichiritsa yokha" poyendetsa deta kudzera m'njira ina.
Sizimangokhala za Zigbee zokha:Ma protocol ambiri amagwiritsa ntchito ma network a mesh.
Bluetooth Meshimagwiritsa ntchito topology ya maukonde koma ndi njira yosiyana ndi ya Zigbee.
Ulusi(yogwiritsidwa ntchito ndi Matter, Google Nest, ndi Amazon Eero) ndi protocol ya maukonde yochokera ku IP.
Z-Waveimagwiritsa ntchito topology ya maukonde koma imagwira ntchito pa ma frequency osiyana a wailesi (908.42 MHz ku US) kuposa Zigbee (2.4 GHz).
4. Ubale
Apa ndi pamene zimakhala zovuta:Zigbee amagwiritsa ntchito netiweki ya maukonde.
Mukagula chipangizo cha Zigbee, chimagwiritsa ntchito topology ya maukonde kuti chiwonjezere kuchuluka kwa maukonde ndikupereka kuchulukirachulukira kwa maukonde. Komabe, si maukonde onse a maukonde omwe ndi a Zigbee.
| Mbali | Zigbee | Mesh (Lingaliro Lonse) |
| Tanthauzo | Muyezo wapadera wa protocol yopanda zingwe | Kapangidwe/kapangidwe ka netiweki |
| Kuchuluka kwa nthawi | 2.4 GHz (padziko lonse lapansi) | Zimasiyana (2.4 GHz ya BT Mesh/Wi-Fi, Sub-GHz ya Z-Wave, ndi zina zotero) |
| Topology | Choyamba ndi Nyenyezi (hub-to-device) ndi Mesh | Nyenyezi, Mtengo, kapena Unyolo |
| Kugwirizana | Zapamwamba (ngati Zigbee 3.0 yavomerezedwa) | Zochepa (kungoti zipangizo ziwiri zimagwiritsa ntchito "maukonde" sizikutanthauza kuti zimatha kulankhula; ziyenera kugwiritsa ntchito njira yomweyo) |
| Zitsanzo | Magetsi a mtundu, masensa a Aqara, SmartThings | Zigbee, Z-Wave, Thread, Bluetooth Mesh, Wi-Fi Mesh (mwachitsanzo, Eero, Orbi) |
5. Chisokonezo Chofala: Zigbee vs. Wi-Fi Mesh
Anthu ambiri amasokoneza Zigbee ndi"Makina a Wi-Fi okhala ndi maukonde"(monga Google Nest Wi-Fi kapena Eero).
Wi-Fi ya Mesh (Eero/Orbi):Izi zapangidwa kuti zilowe m'malo mwa rauta yanu yakunyumba. Zimagwiritsa ntchito topology ya mesh kuti zipereke intaneti yolimba komanso yothamanga kwambiri pakuwonera, kusewera masewera, komanso kusakatula. Zipangizozi zimagwira ntchito pa ma band omwewo a 2.4GHz ndi 5GHz monga momwe zilili ndi Wi-Fi yachikhalidwe.
Unyolo wa Zigbee:Izi zapangidwira zipangizo za intaneti ya zinthu (IoT) zomwe zimakhala ndi mphamvu zochepa. Babu la Zigbee silifuna bandwidth ya 500 Mbps; limafuna njira yodalirika komanso yopanda mphamvu zambiri kuti linene kuti "yatsani."
Chidule
Ngati mukumanga nyumba yanzeru:
Ngati chipangizo chikunena kuti ndiZigbee, zikutanthauza kuti mwina idzalumikizana ndi hub inayake (monga siteshoni ya SmartThings kapena Echo Hub) ndipo idzakhala ngati chobwerezabwereza (mesh) pazida zina za Zigbee.
Ngati chipangizo chikunena kuti ndiUnyolo, muyenera kuyang'ana chithunzi chopyapyala kuti muwone kuti ndi mesh iti yomwe imagwiritsa ntchito (Zigbee, Thread, kapena mesh yapadera) kuti mudziwe ngati igwira ntchito ndi makina anu omwe alipo.
