Kungafinyelelwa Kungakanani Ukuxhumana Okungenantambo kwe-Zigbee kanye ne-Z-Wave?

Isingeniso

Ukuqonda ukusakazwa komhlaba wangempela weZigbeefuthiI-Z-Waveamanethiwekhi anemeshi abalulekile ekuklameni amasistimu asekhaya ahlakaniphile. Yize womabili amaphrothokholi anweba ububanzi bokuxhumana ngokusebenzisa inethiwekhi ye-mesh, yaboizici kanye nemikhawulo engokoqoboahluke.
Lo mhlahlandlela unikeza ukubuka konke okuphelele kwezinto ezithinta ububanzi, ukusebenza kwekhava okulindelekile, namasu afakazelwe okuthuthukisa ukwethembeka kwenethiwekhi - ukukusiza ukuthi wakhe inethiwekhi yasekhaya ehlakaniphile esebenza kahle futhi engalawuleki.

1. Izisekelo Zenethiwekhi Ye-Mesh

I-Mesh networking iyisisekelo sendlela i-Zigbee ne-Z-Wave efinyelela ngayo ukumbozwa kwekhaya lonke. Ngokungafani nezinhlelo zendabuko zokukhomba-kuphoyinti, amanethiwekhi anezikhala anika amandla amadivayisi ukuxhumana ngokubambisana, ukwakhaimizila yedatha yezindlela eziningiezithuthukisa ukungafuneki futhi andise ububanzi bubonke.

Izimiso Eziyisisekelo ze-Mesh Networks

Amanethiwekhi e-Mesh asebenza ngomgomo wokuthiidivayisi ngayinye ingasebenza kokubili njengomthombo wedatha nanjengenodi yokudluliselakwabanye. Lesi sakhiwo esizihlelayo sivumela imilayezo ukuthi ifinyelele lapho iya khona ngokusebenzisa izindlela eziningi, ukuthuthukisa ukubekezelela amaphutha nokwelula ukufinyelela kwenethiwekhi.

Izinhlobo ze-Node Nezindima

Kuzo zombili izinhlelo ze-Zigbee ne-Z-Wave, amadivayisi ahlukaniswa ngezindima zawo zenethiwekhi:

• Umxhumanisi/Umlawuli:Iphatha inethiwekhi futhi iyixhume kumasistimu angaphandle.

• Amadivayisi omzila:Dlulisela phambili idatha yamanye amanodi ngenkathi enza imisebenzi yawo.

• Qeda Amadivayisi:Ngokuvamile inamandla ebhethri futhi ithembele kumarutha ukuze uxhumane.

Multi-Hop Communication

Inzuzo eyinhloko yamanethiwekhi we-mesh ileleukudluliselwa kwe-multi-hop— idatha “ingagxuma” kumadivayisi ambalwa ukuze ifinyelele lapho iya khona. I-hop ngayinye inweba ibanga elingaphezu komugqa oqondile wokubona, kodwa ama-hop amaningi kakhulu akhuphula ukubambezeleka kanye namaphoyinti okuhluleka okungenzeka. Empeleni, amanethiwekhi asebenzisa ama-hops ambalwa kakhulu kunomkhawulo wethiyori.

Ikhono Lokuziphilisa

Amanethiwekhi e-Mesh angakwaziukuzivumelanisa ngokuzenzakalelaizinguquko zemvelo, njengokuhluleka kwedivayisi noma ukuphazamiseka. Uma indlela ekhethwayo ingatholakali, isistimu ithola ezinye izindlela futhi ibuyekeze amathebula omzila. Lesi sici sokuzilapha sibalulekile ekugcineni ukuxhumana okuzinzile ezindaweni eziguqukayo.

2. Izimpawu Zebanga Le-Zigbee
