Uma kufikaukuxhumeka kwekhaya okuhlakaniphile, kukhona okungaphezu nje kobuchwepheshe obujwayelekile njenge-Wi-Fi ne-Bluetooth.Kunemithethonqubo eqondene nemboni ethile, njenge-Zigbee, i-Z-Wave, ne-Thread, ezilungele kangcono izinhlelo zokusebenza zasekhaya ezihlakaniphile.

Emkhakheni we-automation yasekhaya, kunezinhlobonhlobo zemikhiqizo etholakalayo emakethe ekuvumela ukuthi ulawule kalula yonke into kusukela ekukhanyeni kuya ekushiseni.Ngokusetshenziswa kabanzi kwabasizi bezwi njenge-Alexa, Umsizi we-Google, ne-Siri, ungaqinisekisa ukusebenzisana okungenamthungo phakathi kwamadivayisi avela kubakhiqizi abahlukene.

Ngokwezinga elikhulu, lokhu kungenxa yamazinga angenantambo afana ne-Zigbee, i-Z-Wave, ne-Thread.Lawa mazinga avumela ukudluliswa kwemiyalo, njengokukhanyisa isibani esihlakaniphile esinombala othile ngesikhathi esithile, kumadivaysi amaningi ngesikhathi esisodwa, inqobo nje uma unesango lasekhaya elisebenzisanayo elikwazi ukuxhumana nawo wonke amadivayisi akho asekhaya ahlakaniphile.

Ngokungafani ne-Wi-Fi, lezi zindinganiso zasekhaya ezihlakaniphile zisebenzisa amandla amancane, okusho ukuthi amaningiamadivaysi ahlakaniphile asekhayaingasebenza iminyaka ngaphandle kwesidingo sokushintshwa kwebhethri njalo.

Ngakho,uyini ngempela uZigbee?

Njengoba kushiwo ngaphambili, i-Zigbee iyizinga lenethiwekhi engenantambo eligcinwe futhi labuyekezwa inhlangano engenzi nzuzo i-Zigbee Alliance (manje eyaziwa ngokuthi i-Connectivity Standards Alliance), eyasungulwa ngo-2002. Leli zinga lisekelwa izinkampani zobuchwepheshe ezingaphezu kuka-400, okuhlanganisa izikhondlakhondla ze-IT ezifana ne-Apple. , i-Amazon, ne-Google, kanye nemikhiqizo eyaziwa njenge-Belkin, i-Huawei, i-IKEA, i-Intel, i-Qualcomm, ne-Xinnoo Fei.

I-Zigbee ingakwazi ukudlulisa idatha ngokungenantambo phakathi kwamamitha angu-75 kuya kwangu-100 ngaphakathi endlini noma cishe amamitha angu-300 ngaphandle, okusho ukuthi inganikeza ukuvikeleka okuqinile nokuzinzile ngaphakathi kwamakhaya.

Isebenza kanjani i-Zigbee?

I-Zigbee ithumela imiyalo phakathi kwamadivayisi ahlakaniphile asekhaya, afana nokusuka kusipika esihlakaniphile kuye kwibulb noma ukusuka ekushintsheni kuye kusibani, ngaphandle kwesidingo sehabhu yokulawula emaphakathi njengerutha ye-Wi-Fi ukuze kulamule ukuxhumana.Isignali ingathunyelwa futhi iqondwe ngokwamukela amadivayisi, kungakhathaliseki ukuthi umkhiqizi wayo, inqobo nje uma esekela i-Zigbee, angakhuluma ulimi olufanayo.

I-Zigbee isebenza kunethiwekhi ye-mesh, evumela imiyalo ukuthi ithunyelwe phakathi kwamadivayisi axhunywe kunethiwekhi efanayo ye-Zigbee.Ngokombono, idivayisi ngayinye isebenza njenge-node, yamukela futhi idlulisela idatha kuwo wonke amanye amathuluzi, isiza ukusabalalisa idatha yomyalo kanye nokuqinisekisa ukutholakala okubanzi kwenethiwekhi yasekhaya ehlakaniphile.

Kodwa-ke, nge-Wi-Fi, amasignali aba buthaka ngebanga elikhulayo noma angavinjwa ngokuphelele izindonga eziwugqinsi ezindlini ezindala, okusho ukuthi imiyalo ingase ingafinyeleli kumadivayisi asekhaya ahlakaniphile nhlobo.

Isakhiwo se-mesh senethiwekhi ye-Zigbee siphinde sisho ukuthi awekho amaphuzu okuhluleka okukodwa.Isibonelo, uma ikhaya lakho ligcwele ama-smart bulbs ahambisana ne-Zigbee, ungalindela ukuthi zonke zikhanyiswe kanyekanye.Uma enye yazo yehluleka ukusebenza kahle, i-mesh iqinisekisa ukuthi imiyalo isengalethwa kuwo wonke amanye ama-bulb akunethiwekhi.

Nokho, eqinisweni, lokhu kungase kungabi njalo ngaso sonke isikhathi.Nakuba amadivaysi amaningi ahlakaniphile asebenzisa i-Zigbee asebenza njengezixhumanisi zokudlulisa imiyalo kunethiwekhi, amanye amadivaysi angathumela futhi amukele imiyalo kodwa awakwazi ukuyidlulisela phambili.

Njengomthetho ojwayelekile, amadivaysi axhaswe ngumthombo wamandla oqhubekayo asebenza njengama-relay, asakaza wonke amasiginali abawathola kwamanye ama-node kunethiwekhi.Amadivayisi e-Zigbee asebenza ngebhethri ngokuvamile awawenzi lo msebenzi;esikhundleni salokho, bavele bathumele futhi bamukele imiyalo.

Amahabhu asebenzisana ne-Zigbee adlala indima ebalulekile kulesi simo ngokuqinisekisa ukudluliselwa kwemiyalo kumadivayisi afanelekile, ukwehlisa ukuncika ku-Zigbee mesh ekulethweni kwawo.Eminye imikhiqizo ye-Zigbee iza namahabhu ayo.Nokho, amadivayisi ahlakaniphile ahambisana ne-Zigbee angaphinda axhume kumahabhu ezinkampani zangaphandle asekela i-Zigbee, njengezipikha ezihlakaniphile ze-Amazon Echo noma amahabhu e-Samsung SmartThings, ukuze kuncishiswe imithwalo eyengeziwe futhi kuqinisekiswe ukusethwa okulula ekhaya lakho.

Ingabe i-Zigbee ingcono kune-Wi-Fi ne-Z-Wave?

I-Zigbee isebenzisa izinga le-IEEE's 802.15.4 Personal Area Network ekuxhumaneni futhi isebenza kumafrikhwensi angu-2.4GHz, 900MHz, kanye no-868MHz.Izinga layo lokudluliswa kwedatha lingu-250kB/s kuphela, lihamba kancane kakhulu kunanoma iyiphi inethiwekhi ye-Wi-Fi.Kodwa-ke, ngenxa yokuthi i-Zigbee idlulisela kuphela amanani amancane edatha, isivinini sayo esinensayo asiyona into ekhathazayo.

Kunomkhawulo enanini lamadivayisi noma amanodi angaxhunywa kunethiwekhi ye-Zigbee.Kodwa abasebenzisi basekhaya abahlakaniphile akudingeki bakhathazeke, njengoba le nombolo ingakhuphukela kuma-node angu-65,000.Ngakho-ke, ngaphandle uma wakha indlu enkulu ngendlela engavamile, yonke into kufanele ixhume kunethiwekhi eyodwa ye-Zigbee.

Ngokuphambene, obunye ubuchwepheshe basekhaya obuhlakaniphile obungenawaya, i-Z-Wave, bukhawulela inani lamadivayisi (noma amanodi) libe ngu-232 ihabhu ngayinye.Ngalesi sizathu, i-Zigbee ihlinzeka ngobuchwepheshe bekhaya obuhlakaniphile obungcono, kucatshangwa ukuthi unendlu enkulu kakhulu futhi uhlele ukuyigcwalisa ngamadivayisi ahlakaniphile angaphezu kuka-232.

I-Z-Wave ingadlulisela idatha kumabanga amade, cishe amafidi angu-100, kanti ububanzi bokudlulisela be-Zigbee buwela phakathi kwamafithi angu-30 no-60.Kodwa-ke, uma kuqhathaniswa ne-Zigbee's 40 to 250kbps, i-Z-Wave inesivinini esinejubane, ngezinga lokudluliswa kwedatha elisuka ku-10 kuya ku-100 KB ngomzuzwana.Zombili zihamba kancane kune-Wi-Fi, esebenza ngamamegabhithi ngomzuzwana futhi ingadlulisela idatha phakathi kwamafithi angu-150 kuya kwangu-300, kuye ngezithiyo.

Yimiphi imikhiqizo yasekhaya ehlakaniphile esekela i-Zigbee?

Nakuba i-Zigbee ingase ingabi yonke indawo njenge-Wi-Fi, ithola uhlelo lokusebenza ngenani elimangalisayo lemikhiqizo.I-Connectivity Standards Alliance inamalungu angaphezu kuka-400 avela emazweni angu-35.Umfelandawonye uphinde uthi okwamanje kunemikhiqizo eqinisekisiwe ye-Zigbee engaphezu kuka-2,500, nokukhiqizwa okunqwabelanayo okudlula amayunithi ayizigidi ezingama-300.

Ezimweni eziningi, i-Zigbee ubuchwepheshe obusebenza buthule ngemuva kwezindlu ezihlakaniphile.Kungenzeka ukuthi ufake isistimu yokukhanyisa ehlakaniphile ye-Philips Hue elawulwa yi-Hue Bridge, ngaphandle kokuqaphela ukuthi i-Zigbee inika amandla ukuxhumana kwayo okungenantambo.Lona umnyombo we-Zigbee (kanye ne-Z-Wave) namazinga afanayo—ahlala esebenza ngaphandle kokudinga ukucushwa okubanzi njenge-Wi-Fi.
