Ubuchwepheshe obungenazintambo ngokusetshenziswa kwezohwebo
Incazelo yezobuchwepheshe yeZigBee yukuthi iyinhlangano yokuxhumana engenazintambo evulekile esekelwe kumklamo wenethiwekhi ojwayelekile usebenzisa i- OSI model ngokusebenzisa i-IEEE 802.15.4-2006 IP ungqimba.
NgesiNgisi esicacile, cabanga ngoZigbee njengelulwimi amadivaysi asetshenziswa ukukhuluma omunye nomunye. I-ZigBee 'ikhuluma' ngemibandela efanayo ukuthi idivayisi ye- Bluetooth noma engenantambo ingahle ibe khona. Lokhu kusho ukuthi bangakwazi ukuxhumana ngaphandle kobunzima obukhulu. Isebenza futhi kumadivayisi aphansi angenawo amandla, ngakho-ke uma idivayisi ilele, uZigbee angathumela isignali ukuze avule ukuze baqale ukuxhumana. Ngenxa yalesi sizathu, kuyisiphakamiso esithandwayo sokuxhumana esisetshenziswe kumadivayisi smart ekhaya . Zisihluthulelo sokukhumbula, noma kunjalo, ukuthi yiZigbee ekhuluma namadivaysi, ngakho-ke iyingxenye ye- Internet yezinto (IoT) .
Indlela iZigbee ekhuluma ngayo
Amadivaysi e-ZigBee aklanyelwe ukuxhumana ngezikhathi zomsakazo. U-ZigBee usemukele i- 2.4 GHz yemvamisa yayo evamile emhlabeni jikelele. Ngenxa yokuphazamiseka komkhawulokudonsa, iZigBee isebenzisa i-915 MHz e-United States ne-866 MHz eYurophu.
Amadivaysi e-ZigBee angama-3 izinhlobo, abaxhumanisi, ama-Routers, nama-End Devices.
- Abaxhumanisi balawula ukubunjwa kwenethiwekhi nokuvikeleka.
- Ama-routers adlulisela isignali futhi anwebe ububanzi benethiwekhi.
- Amadivayisi Ekupheleni enza imisebenzi ethize efana nokuvula ukukhanya noma ukuthatha ukufunda.
Yiwona amadivaysi ekuphela esikukhathalele kakhulu. Isibonelo, kungenzeka ukuthi uke wabona uZigbee ehlotshaniswa nomndeni wemikhiqizo ye-Philips Hue. I-Zigbee yilokho okuqondisa amasignali angenawaya asetshenziselwa ukulawula la madivaysi, futhi afakwa kwezinye izinhlobo zemikhiqizo, njengokushintshwa okuhlakaniphile, ama-plug smart, nama-thermostats ahlakaniphile.
I-ZigBee ku-Home Automation
Amadivaysi e-ZigBee asephuzile ekutholeni ukwamukelwa emakethe yezakhi ezakhiwe ekhaya ngoba ziwumthombo ovulekile, okusho ukuthi i-protocol ingashintshwa ngumenzi ngamunye owamukelayo. Njengoba amadivaysi omphumela avela kumkhiqizi oyedwa ngezinye izikhathi abe nobunzima bokuxhumana namadivayisi avela kumkhiqizi ohlukile. Lokhu kungenza inethiwekhi yekhaya ibe nokusebenza okuncane futhi okuncane.
Kodwa-ke, njengoba umqondo wokukhula kwekhaya ohlakaniphile, uyaba ovame kakhulu ngoba uvumela ukulawula okubanzi ngenombolo encane ye- hubs smart . Isibonelo, i-GE, i-Samsung, i-Logitech, ne-LG yonke ikhiqiza amadivaysi asekhaya ahlakaniphile asebenzisa i-Zigbee. Ngisho i-Comcast ne-Time Warner ifake i-Zigbee emabhokisini azo aphezulu, kanti i-Amazon iyifake ku- Echo Plus entsha, engasetshenziswa njenge-hub smart. I-Zigbee isebenza namadivayisi aphethwe ngamabhethri, afaka amandla.
Ukuwa okuyinhloko uma usebenzisa i-Zigbee ibanga elikhuluma ngalo. Lokhu kungamamitha angu-35 (amamitha angu-10) ngenkathi amanye ama-protocol axhumana nawo angakwazi ukuxhumana kuze kube ngamamitha angu-30. Noma kunjalo, ukwehluleka kwamanani kunqotshwa yiqiniso lokuthi uZigbee ukhuluma ngesivinini esikhulu kunezinye izindinganiso zokuxhumana. Ngakho-ke, amadivaysi e-Z-Wave angaba nobubanzi obuningi, kodwa iZigbee ixhumana ngokushesha, ngakho imiyalo ikwenza kusuka kudivayisi eyodwa kuya ngokushesha ngokunciphisa isikhathi esidingekayo kusuka kumyalo kuya kwesenzo, noma isibonelo, ukunciphisa isikhathi kusuka lapho usho , "Alexa, vula isibani sokulala," kuze kube yisikhathi isibani esishintsha ngempela.
ZigBee ku-Applications zezohwebo
Amadivaysi e-ZigBee nawo ayaziwa ukuthi ayaphumelela kwizicelo zezohwebo ngenxa yamakhono ayo kwi-intanethi yezinto. Umklamo we-ZigBee uzivumela ukuzwa nokuqapha izinhlelo zokusebenza futhi ukusetshenziswa kwayo ekuqapha okukhulu kwezingcingo kukhula ngokushesha. Futhi, ukufakwa okuningi kwe-IOT kusebenzisa imikhiqizo evela kumkhiqizi oyedwa kuphela, noma uma sebenzisa okungaphezu kweyodwa, imikhiqizo ivivinywa ngokuphelele ukuhambisana ngaphambi kokufakwa.
