Ngaphambi kokuba siZigin...
Kukho iiprothokholi ezimbini eziphambili zalo naliphi na iKhaya eliSmart, ezi ziZigbee kunye neZ-Wave. Kukho ingxoxo eninzi malunga nokuba yeyiphi eyona ndlela ilungileyo, kodwa kule post, ndiza kuchaza ukuba yintoni le teknoloji, isetyenziswa njani kwaye kutheni ilungile / imbi.
Oku kuya kuba kukujongwa okunzulu kwiZigbee (Kwaye ezinye ze-Z-wave), ukukubonisa amandla apheleleyo kunye neemfuno zobugcisa zobuchwephesha.
IAmazon isandula ukukhankanya ukuba intsha yabo I-4th-gen Echo iya kusebenza njenge-Zigbee hub, okuthetha ukuba sinokulindela ukubona iimveliso ze-Amazons Smart Home zifikelela kwezinye i-ecosystems zaseKhaya.
UGoogle, iAmazon kunye neApple zonke zijoyina iZigbee Alliance. Oku kuthetha ukuba i-Smart Homes efudukela kwixesha elizayo iya kuhambelana nezinye izixhobo ezininzi.
Yintoni iZigbee?
I-Zigbee yiprothokholi esebenza kakhulu njengenethiwekhi yemesh, oku kuthetha ukuba endaweni yesixhobo ngasinye esisebenzisa iZigbee ukuqhagamshela kwinethiwekhi yakho yeWiFi, baqhagamshela kwindawo esembindini endaweni yoko.
I-Wi-Fi kunye neBluetooth ayilunganga ekudibaniseni izixhobo kwinethiwekhi enye, kulapho iZigbee hub ingena khona.
I-Zigbee isekwe kumgangatho wothungelwano we-IEEE we-802.15.4 wobuqu, ngokusisiseko, oku kuthetha ukuba iinkcukacha ze-Zigbee zinexesha elide kuneshumi leminyaka.
Ihlala ithathwa njengenye indlela yeWiFi kunye neBluetooth, kufanele kukhankanyiwe ukuba iZigbee isebenzisa umda ongaphantsi kakhulu kwaye isebenza ngcono kwizixhobo ezinamandla aphantsi.
I-Zigbee ithathwa njengenye yemigangatho emibini yenethiwekhi ye-automation yasekhaya
Kutheni uZigbee elunge kangaka?
IZigbee inophawu olulodwa oluyenza ingakholeleki; akukho mfuneko ye hub esembindini njengoko kunokwenzeka ukuba izixhobo zithumele idatha ukusuka kwenye ukuya kwenye ukwenza umnatha.
Umgaqo jikelele wesithupha kukuba ayizizo zonke izixhobo zeZigbee ezinokusebenza ngendlela yokuphinda umnatha.
Umgaqo jikelele webhontsi kukuba inikwe amandla rhoqo, njenge Iplagi efanelekileyo or I-Smart Bulb, iya kusebenza njenge-mesh repeater.
Njengoko iZigbee isekwe kumgangatho womnatha we-IEEE we-802.15.4, ibavumela ukuba bafikelele kuluhlu oluphezulu lweemitha ezingama-300 (Kucingelwa ukuba akukho zindonga endleleni).
Ngokuqhelekileyo oku kuthetha ukuba uya kubona naphi na ukusuka kwi-70 - 100 yeemitha xa useka ngaphakathi.
IZigbee isebenza kwiifrikhwensi ezahlukeneyo ezahlukeneyo, ezi ziyi-2.4GHZ, 868MHz & 90MHz.
I-Zigbee nayo inezinga losulelo lwe-250kbps, esi sisantya esisezantsi kakhulu kunoqhagamshelo oluninzi lwe-WiFi, oku kusebenza kakuhle kuba isasaza kuphela ekuhlaleni ukuya kuthi ga kwi-65 iinyawo ejikeleze ikhaya lakho. Ke, kule meko, isezantsi ingcono.
Oku kuya kuba kuhle kuzo naziphi na izinzwa onazo ezifuna ukuthumela idatha kunye nokusuka kwi-hub yakho engundoqo ngenxa yeemfuno zamandla asezantsi.
Yintoni iNethiwekhi yeMesh kwaye kutheni kufuneka ndisebenzise enye?
Oku kunokubhida kakhulu, kulo mzekelo ndiza kuzama ukwahlula oku kulandelayo:
- Umququzeleli weZigbee
- Zigbee Router
- Isixhobo seZigbee
Isixhobo seZigbee yiyo nantoni na oyibonayo, ngoko ke, ibhalbhu yesibane okanye isivamvo njl.njl. IziXhobo zeZigbee zonke ziqhagamshelana kwirutha yeZigbee ngokufanelekileyo kwaye zonke iirutha zeZigbee ziqhagamshela kuMnxibelelanisi weZigBee omnye. Kufana neqela labantu abanxibelelana ukuya kutsho kwinkokeli enye.
Ngethemba lo mfanekiso omncinci onemibala uyanceda, ngokusisiseko, iDivaysi (Eyaziwa ngokuba yiModyuli) iyakuqhagamshela kwiRouter (i-node) ethi emva koko iqhagamshele kwiSixhobo (Inethiwekhi engundoqo).
Oku kunciphisa idatha yokudlulisa ulwazi njengoko iiNodes zisebenza njenge-transmitter encinci.
Le inethiwekhi ezinzile kakhulu, ngokungathi umzila omnye uya ezantsi, kusekho ezinye iindawo womnatha ukuba phezulu kwaye isebenza.
Elona xesha lokwenyani lokuphela liya kuba ukuba uMnxibelelanisi uyekile ukusebenza nto leyo eya kuba luvavanyo olulula.
Ungaphinda usebenzise inethiwekhi yeWiFi kwiseti ye-mesh, kodwa yinto yelinye ixesha!
Ukonakaliswa kwetekhnoloji yeZigbee
Kukho amacandelwana ahlukeneyo kolu lwahlulelo, ke ndiyakwenza konke okusemandleni am ukwenza oku kube lula ukufundeka kangangoko.
Amandla aphantsi kunye nothelekiso
Inqaku elipheleleyo leKhaya le-Smart kukugcina imali, ukuphucula ngokufanelekileyo indlela yakho yokuphila kwaye hayi uxinzelelo. Nge-WiFi kunye neBluetooth amandla alambileyo, akumangalisi ukuba olu lolona khetho lufanelekileyo.
Uninzi lwezixhobo zakho ziya kusebenza kwiibhetri (Iikhamera zokuqhwanyaza ngokomzekelo), njengoko uya kufuna iprotocol yonxibelelwano ukuba isebenzise kancinci kakhulu loo mandla ebhetri.
I-Zigbee isebenzisa amandla angaphantsi kakhulu kune-Z-Wave, ke ngokugqabhuka okuncinci, ilungile kakhulu!
Uluhlu loMqondiso kunye nokuFikelela
Ngokwandiswa kwetekhnoloji yeKhaya le-Smart kule minyaka imbalwa idlulileyo, kulindeleke ukuba ufune ukufikelela ngakumbi kwiimpawu zesixhobo sakho.
I-Zigbee inoluhlu lweenyawo ze-65, ucinga ukuba akukho nto ithintela ngokuthe ngqo. Oku akulunganga kakhulu malunga noluhlu lweempawu kodwa ayimangalisi ncam, ngaphakathi ndingalindela naphi na phakathi kwe-30 kunye ne-45 yeenyawo. Kodwa oku kusekelwe kuphela kumgca wokubona.
Kutheni umqondiso unokuba mbi kangaka?
Iifrikhwensi zophawu oluphezulu azikwazi ukungena kwiindonga okanye ifenitshala ngelishwa, kuba ungcono ukuseta ii-hubs ezininzi ejikeleze indlu yakho kwaye ube noMnxibelelanisi wakho oPhambili kwindawo apho zonke iirutha zinokuqhagamshelwa ngcono.
Oku akulunganga kumakhaya amakhulu alumkileyo, kodwa kukwamkeleka ngakumbi ukusetwa kuloo meko. Ukuba unemigangatho emininzi, ngokuqinisekileyo yiba ne-router eyahlukileyo kumgangatho ngamnye ukuba unako.
Kuthekani ngokuthembeka kweZigbee?
Njengoko kukhankanyiwe ngasentla, uphawu lunokuba lubi, oku kuthetha ukuba ukuxhomekeka kunokuchaphazeleka. Masithi une-Smart Lock engakwaziyo ukuqhagamshela kwi-hub yakho, kuthetha ukuthini oku?
Ukubeka nje, awuyi kukwazi ukuvula i-Smart Lock kuba ayikwazi ukuthumela uphawu kunye nokusuka kwi-hub ngokuchanekileyo.
Kodwa, ukuba oku kumiselwe ngokuchanekileyo, yiyo kanye le nto sifuna iZigbee. Ndithetha ukuthini kanye kanye?
I-Zigbee ilungile, isihogo, isebenza kakuhle ukuba uyayimisa ngokuchanekileyo.
Loluphi uhlobo lwe hub endiyifunayo kwiZigbee?
Ukuba nezixhobo zeZigbee kwinethiwekhi yakho kufuna ihabhu kunye nesicwangciso kwangethuba ukuzihlanganisa ngokuchanekileyo.
I-Amazon ithathe oku ngesivunguvungu kutshanje, i-Echo Plus kunye ne-Echo Show 10 isebenza njenge-Zigbee Hub. I I-Eero Mesh Pro ikwalukhetho oluhle njengoko lungasebenzi nje njengerouter kodwa iZigbee Hub.
Ukuba ujonge into yangaphandle kwilizwe leAmazon, ezinye iingcebiso ezintle ziyiSamsung SmartThings, Wink kunye neAbode. Ngokomntu, ndihlala ndicebisa i-SmartThings Hub kulo mzekelo
Zihambelana njani izixhobo ezininzi kangaka?
Oku kungenxa yeqela elibizwa ngokuba yiZigbee Alliance, oku kuthetha ukuba ngaphezulu kwezixhobo ezingama-2500 zilungele iZigbee. Kukho iSiqinisekiso seZigbee seKhaya eliZisebenzelayo esibonisa ukuba zeziphi izixhobo ezihambelana ngokupheleleyo neZigbee.
Ezinye zeemveliso eziqhelekileyo onokuthi ungazi ukuba iZigbee ziyahambelana zezi:
- IAmazon Echo Plus
- Belkin WeMo
- Ikea Tradfri
- UPhilips Hue (Usebenzisa i-signify)
- Samsung Smart Izinto
- Yale Smart Locks
- I-Honeywell Thermostats
Umanyano lweZigbee
I-Zigbee Alliance yenziwe ngabadali beli teknoloji kwi-2002 kwaye inamalungu angama-400 kunye nezixhobo ze-2500 + ezixhaswayo.
Kukho malunga ne-500 yezigidi zeZigbee chipsets ezithengisiweyo, bekulindeleke ukuba iibhiliyoni ezi-4 zithunyelwe ngenqanawa ngo-2023 (Kodwa kubonakala ngathi i-Covid-19 iyiyekile loo nto).
Kukho amanqanaba ama-3 kubulungu beZigbee (Okokubiza imali yonke ukuyijoyina), ngala: Ummkeli, uMthathi-nxaxheba & Umxhasi.
Ngaba kunokwenzeka ukuqhagamshela iZigbee kwiPC?
Ngokwethiyori, ewe. Unokusebenzisa iArduino kwaye uqhagamshele nge-USB. Ngokukodwa, jonga kwi XBee ikhaka.
Oku kuya kufuna ukufunda okuninzi kwaye ekugqibeleni ikhowudi yesiko oyenzela wena okanye uluntu lwaseArduino.
