Xa kufikwa kusmart uqhagamshelo ekhaya, kukho okungakumbi kunobuchwepheshe obuqhelekileyo njenge-Wi-Fi kunye neBluetooth.Kukho iiprothokholi ezithe ngqo kwishishini, njengeZigbee, i-Z-Wave, kunye ne-Thread, ezilunge ngakumbi kwizicelo ezihlakaniphile zasekhaya.

Kwindawo ye-automation yasekhaya, kukho uluhlu olubanzi lweemveliso ezikhoyo kwimarike ekuvumela ukuba ulawule yonke into ngaphandle kokukhanya ukuya kushushu.Ngokusetyenziswa ngokubanzi kwabancedisi belizwi abanje nge-Alexa, uMncedisi kaGoogle, kunye neSiri, unokuqinisekisa ukusebenzisana okungenamthungo phakathi kwezixhobo ezivela kubavelisi abohlukeneyo.

Ubukhulu becala, oku kubulela kwimigangatho engenazingcingo njengeZigbee, Z-Wave, kunye neThread.Le migangatho ivumela ukuhanjiswa kwemiyalelo, enjengokukhanyisa ibhalbhu enemibala ethile ngexesha elithile, kwizixhobo ezininzi ngaxeshanye, ngaphandle kokuba unesango lekhaya elihambelanayo elinokunxibelelana nazo zonke izixhobo zakho zasekhaya ezihlakaniphile.

Ngokungafaniyo ne-Wi-Fi, le migangatho yasekhaya ehlakaniphile idla amandla amancinci, okuthetha ukuba amaninziizixhobo smart ekhayainokusebenza iminyaka ngaphandle kwesidingo sokutshintshwa rhoqo kwebhetri.

Ngoko,yintoni kanye kanye uZigbee?

Njengoko kukhankanyiwe ngaphambili, iZigbee ngumgangatho womnatha ongenazingcingo ogcinwe kwaye uhlaziywe ngumbutho ongenzi nzuzo iZigbee Alliance (ngoku eyaziwa ngokuba yi-Connectivity Standards Alliance), esekwe ngo-2002. Lo mgangatho uxhaswa ngaphezu kweenkampani zeteknoloji ze-400, kuquka i-IT giants njenge-Apple. , Amazon, kunye noGoogle, kunye neempawu ezaziwayo ezifana neBelkin, Huawei, IKEA, Intel, Qualcomm, kunye neXinnoo Fei.

I-Zigbee inokusasaza idatha ngaphandle kwamacingo malunga ne-75 ukuya kwi-100 yeemitha ngaphakathi okanye malunga ne-300 yeemitha ngaphandle, okuthetha ukuba inokubonelela ngokhuseleko oluqinileyo noluzinzileyo ngaphakathi kwezindlu.

Usebenza njani uZigbee?

I-Zigbee ithumela imiyalelo phakathi kwezixhobo ezihlakaniphile zasekhaya, ezifana nokusuka kwisithethi esihlakaniphile ukuya kwibhalbhu yesibane okanye ukusuka kwisitshixo ukuya kwibhalbhu, ngaphandle kwesidingo sehabhu yolawulo esembindini njengerutha ye-Wi-Fi ukulamla unxibelelwano.Isibonakaliso sinokuthunyelwa kwaye siqondwe ngokufumana izixhobo, kungakhathaliseki ukuba ngumenzi wabo, nje ukuba baxhasa iZigbee, banokuthetha ulwimi olufanayo.

IZigbee isebenza kumnatha womnatha, ivumela imiyalelo ukuba ithunyelwe phakathi kwezixhobo eziqhagamshelwe kuthungelwano olufanayo lweZigbee.Ngokwethiyori, isixhobo ngasinye sisebenza njenge-node, sifumana kwaye sithumela idatha kuzo zonke ezinye izixhobo, ukunceda ukusasaza idatha yomyalelo kunye nokuqinisekisa ukugubungela okubanzi kwenethiwekhi yasekhaya ehlakaniphile.

Nangona kunjalo, nge-Wi-Fi, iisignali ziba buthathaka ngokunyuka komgama okanye zinokuvalwa ngokupheleleyo ziindonga ezishinyeneyo kwizindlu ezindala, okuthetha ukuba imiyalelo ayinakufikelela kwezona zixhobo zikude kakhulu ekhaya.

Ulwakhiwo lwe-mesh yenethiwekhi yeZigbee ikwathetha ukuba akukho manqaku okusilela.Umzekelo, ukuba ikhaya lakho lizaliswe ziiglowubhu ezihambelana neZigbee, unokulindela ukuba zonke zikhanyiswe ngaxeshanye.Ukuba enye yazo iyasilela ukusebenza ngokuchanekileyo, umnatha uqinisekisa ukuba imiyalelo isenokuhanjiswa kuzo zonke ezinye iibhalbhu kuthungelwano.

Nangona kunjalo, enyanisweni, oku akusoloko kunjalo.Ngelixa izixhobo ezininzi ezihambelana neZigbee zasekhaya zisebenza njengodluliselo lokudlulisa imiyalelo kwinethiwekhi, ezinye izixhobo zinokuthumela kwaye zifumane imiyalelo kodwa azikwazi ukuyithumela.

Njengomthetho jikelele, izixhobo ezixhaswa ngumthombo wamandla oqhubekayo zisebenza njengeelayidi, zisasaza yonke imiqondiso abayifumanayo kwezinye iindawo kwinethiwekhi.Izixhobo zeZigbee ezisebenza ngebhetri aziwenzi lo msebenzi;endaweni yoko, bathumela nje kwaye bafumane imiyalelo.

Ii-hubs ezihambelana ne-Zigbee zidlala indima ebalulekileyo kule meko ngokuqinisekisa ukuhanjiswa kwemiyalelo kwizixhobo ezifanelekileyo, ukunciphisa ukuxhomekeka kwi-Zigbee mesh ekuhanjisweni kwazo.Ezinye iimveliso zeZigbee ziza kunye neehabhu zazo.Nangona kunjalo, izixhobo zasekhaya ezihambelana neZigbee ziyakwazi ukudibanisa kwii-hubs zomntu wesithathu ezixhasa iZigbee, ezifana nezithethi ezihlakaniphile ze-Amazon Echo okanye i-Samsung SmartThings hubs, ukunciphisa imithwalo eyongezelelweyo kunye nokuqinisekisa ukuseta okulungelelanisiweyo kwikhaya lakho.

Ngaba iZigbee ingcono kuneWi-Fi kunye neZ-Wave?

I-Zigbee isebenzisa umgangatho we-IEEE's 802.15.4 Personal Area Network kunxibelelwano kwaye isebenza kwiifrikhwensi ze-2.4GHz, 900MHz, kunye ne-868MHz.Izinga logqithiso lwedatha yi-250kB/s kuphela, icotha kakhulu kunayo nayiphi na inethiwekhi ye-Wi-Fi.Nangona kunjalo, ngenxa yokuba i-Zigbee ihambisa kuphela amanani amancinci edatha, isantya sayo esicothayo asiyona inkxalabo ebalulekileyo.

Kukho umda kwinani lezixhobo okanye iindawo ezinokudityaniswa kwinethiwekhi yeZigbee.Kodwa abasebenzisi basekhaya abakrelekrele akufuneki bakhathazeke, njengoko eli nani linokunyuka liye kuthi ga kwi-65,000 nodes.Ke, ngaphandle kokuba wakha indlu enkulu ngokungaqhelekanga, yonke into kufuneka iqhagamshelane nenethiwekhi yeZigbee enye.

Ngokwahlukileyo, enye iteknoloji yasekhaya engenazingcingo, iZ-Wave, inciphisa inani lezixhobo (okanye iinodi) ukuya kuma-232 kwindawo nganye.Ngesi sizathu, iZigbee ibonelela ngetekhnoloji ephucukileyo yasekhaya, ucinga ukuba unendlu enkulu kakhulu kwaye ucwangcise ukuyigcwalisa ngezixhobo ezikrelekrele ezingaphezu kwama-232.

I-Z-Wave inokusasaza idatha kumgama omde, malunga neemitha ezili-100, ngelixa uluhlu losasazo lwe-Zigbee luwela phakathi kwe-30 kunye ne-60 yeenyawo.Nangona kunjalo, xa kuthelekiswa ne-Zigbee ye-40 ukuya kwi-250kbps, i-Z-Wave inezantya ezicothayo, kunye namazinga okudlulisa idatha ukusuka kwi-10 ukuya kwi-100 KB ngesekhondi.Zombini zicotha kakhulu kune-Wi-Fi, esebenza kwi-megabits ngesekhondi kwaye inokuhambisa idatha ngaphakathi kwe-150 ukuya kwi-300 yeenyawo, ngokuxhomekeke kwimiqobo.

Zeziphi iimveliso zasekhaya ezihlakaniphile ezixhasa iZigbee?

Ngelixa iZigbee isenokungabikho kuyo yonke indawo njenge-Wi-Fi, ifumana isicelo kwinani elimangalisayo leemveliso.I-Connectivity Standards Alliance inamalungu angaphezu kwama-400 asuka kumazwe angama-35.Umanyano lukwachaza ukuba ngoku kukho ngaphezulu kwe-2,500 yeemveliso eziqinisekisiweyo zeZigbee, kunye nemveliso eyongezelelekileyo edlula iiyunithi zezigidi ezingama-300.

Kwiimeko ezininzi, i-Zigbee iteknoloji esebenza ngokuthula kwimvelaphi yamakhaya ahlakaniphile.Usenokuba ufake i-Philips Hue smart lighting system elawulwa yi-Hue Bridge, ngaphandle kokuqonda ukuba i-Zigbee inika amandla unxibelelwano olungenazingcingo.Lo ngundoqo weZigbee (kunye neZ-Wave) kunye nemigangatho efanayo-baqhubeka besebenza ngaphandle kokufuna uqwalaselo olubanzi njenge-Wi-Fi.
