Itandukaniro riri hagati ya Zigbee na Mesh

Iyi ni ingingo ikunze kugaragara cyane mu rujijo, kuko aya magambo yombi akunze kuvugwa hamwe ariko akaba yerekeza ku bintu bitandukanye.

Uburyo bworoshye bwo kubivuga ni ubu:Zigbee ni ururimi, mu gihe Mesh ari uburyo bwo kuvuga.

Dore isesengura rirambuye ry'itandukaniro.

1. Itandukaniro ry'ingenzi

Inyukiniporotokole(urutonde rw'amahame ngenderwaho y'itumanaho). Isobanura uburyo ibikoresho byigaragaza, uburyo byubaka amakuru, n'uko byinjira mu muyoboro w'itumanaho. Ni ikoranabuhanga ryihariye rifitwe na Connectivity Standards Alliance (CSA).

Umwobonitopolojia y'urusobe rw'amakuru(imiterere y'imiterere). Ni uburyo bwo guhuza ibikoresho aho buri node yohereza amakuru y'umuyoboro. Porotokole iyo ari yo yose ishobora gukoresha topolojia ya mesh, ariko si bose babikora.

2. Zigbee ni iki?

Zigbee ni igipimo cy’itumanaho ridafite insinga gifite ingufu nke kandi gikoresha amakuru make cyubatswe hejuru y’igipimo cya IEEE 802.15.4 cy’amaradiyo.

Intego:Yagenewe porogaramu zikoresha ingufu nke kandi zifite umuvuduko muto nka sensors zo mu rugo zigezweho, amatara, n'ingufuri.

Ubwubatsi:Bishingiye kuriUmuhuzabikorwa(ihuriro/irembo). Mu bikorwa byinshi by’abaguzi (nka Philips Hue cyangwa Amazon Echo Plus), hari igikoresho kimwe cy’ingenzi gikora nk' "ubwonko" bwo gukora no gucunga umuyoboro.

Gukorana neza:Kubera ko ari protocole isanzwe, switch y'amatara ya Zigbee iva muri sosiyete A igomba (mu buryo bw'imitekerereze) gukorana n'amatara ya Zigbee iva muri sosiyete B, mu gihe basangiye porogaramu imwe (nka Zigbee 3.0).

3. Mesh ni iki?

Mesh yerekeza ku buryo ibikoresho bivugana. Mu muyoboro wa mesh, buri gikoresho (cyangwa "node") gishongeshejwe ku ngufu gishobora gukora nka router.

Uko bikora:Aho kugira ngo buri gikoresho gihuze neza na router yo hagati (nka Wi-Fi), ibikoresho bihuzwa n'umuturanyi wabyo wa hafi. Iyo igikoresho kimwe kinaniwe, umuyoboro "wikiza" binyuze mu kohereza amakuru mu nzira itandukanye.

Ntabwo ari Zigbee gusa:Porotokole nyinshi zikoresha imiyoboro ya mesh.

Bluetooth Meshikoresha topolojia ya mesh ariko ni protocole itandukanye na Zigbee.

Umugozi(ikoreshwa na Matter, Google Nest, na Amazon Eero) ni protocole ya mesh ishingiye kuri IP.

Z-Waveikoresha topolojia y'amajwi ariko ikora ku murongo wa radiyo utandukanye (908.42 MHz muri Amerika) n'uwa Zigbee (2.4 GHz).

4. Umubano

Aha niho birushaho kugorana:Zigbee ikoresha umuyoboro w'amasasu.

Iyo uguze igikoresho cya Zigbee, kiba gikoresha topology ya mesh kugira ngo cyongere uburebure no gutanga ubunini. Ariko, si imiyoboro yose ya mesh ari Zigbee.

5. Urujijo Rusanzwe: Zigbee vs. Wi-Fi Mesh

Abantu benshi bitiranya Zigbee na"Sisitemu za Wi-Fi zo mu bwoko bwa Mesh"(nka Google Nest Wi-Fi cyangwa Eero).

Wi-Fi y'urukuta (Eero/Orbi):Ibi byagenewe gusimbura router yawe yo mu rugo. Bikoresha topology ya mesh kugira ngo bitange interineti ikomeye kandi ifite bandwidth nyinshi yo kureba, gukina imikino, no kureba. Ibi bikoresho bikora kuri bande imwe ya 2.4GHz na 5GHz nk'iya Wi-Fi isanzwe.

Uduti twa Zigbee:Ibi byagenewe ibikoresho bya interineti y'ibintu (IoT) bifite ingufu nke. Itara rya Zigbee ntirikenera umuyoboro wa bandwidth wa 500 Mbps; rikeneye uburyo bwizewe kandi bufite ingufu nke bwo kuvuga ngo "fungura".

Incamake

Niba uri kubaka inzu nziza:

Iyo igikoresho kivuze ko ariInyuki, bivuze ko ishobora guhuza n'urubuga runaka (nk'urubuga rwa SmartThings cyangwa Echo Hub) kandi igakora nk'igikoresho cyo gusubiramo (mesh) ku zindi mashini za Zigbee.

Iyo igikoresho kivuze ko ariUmwobo, ugomba kureba ku gishushanyo gito kugira ngo urebe mesh ikoresha (Zigbee, Thread, cyangwa mesh yihariye) kugira ngo umenye niba izakorana na sisitemu yawe isanzwe.
