Kutheni iSmart Home Systems isebenzisa iiModyuli zeBluetooth?
Ngophuhliso olunzulu loluntu lwe-Intanethi kunye nokuphuculwa okuqhubekayo kwemigangatho yokuphila yabantu, umkhwa wokuzenzekelayo kunye nobukrelekrele utshayela ihlabathi, kwaye ingcamango yekhaya elihlakaniphile inyuke ngokukhawuleza. Ukunyuka kunye nophuhliso lwe-Intanethi yeZinto kunye nobuchwepheshe be-sensor buye bazisa inkangeleko entsha kwishishini lasekhaya elihlakaniphile. Namhlanje, umhleli uya kukuthatha ukuba uqonde ukuba kutheni amakhaya ahlakaniphile asebenzisa iimodyuli zeBluetooth.
I-Bluetooth ngumgangatho wobuchwepheshe obungenazingcingo ovumela utshintshiselwano lwedatha yoluhlu olufutshane phakathi kwezixhobo ezisisigxina kunye nezihambayo kunye nothungelwano lwendawo yomntu kwizakhiwo. Imodyuli yeBluetooth yimodyuli esebenzisa iteknoloji engenazingcingo yeBluetooth kuthumelo lweBluetooth. Uqhagamshelwano lwangaphandle lwemodyuli yeBluetooth kunye nokusingqongileyo kwenethiwekhi kunye noqhagamshelwano lwangaphakathi kunye nenkqubo yokusebenza idlala indima ebaluleke kakhulu kwinkqubo yasekhaya ehlakaniphile. Imodyuli yeBluetooth inokudibanisa izixhobo ezininzi, yoyise ingxaki yongqamaniso lwedatha, kwaye isetyenziswa ikakhulu kwezinye izixhobo ezincinci zasekhaya ezihlakaniphile. Imodyuli yeBluetooth yenza ukuba i-terminal ipapashe, ifumane kwaye iqhube ulwazi. Ngophuhliso lweBluetooth, zonke izixhobo zolwazi zeBluetooth zinokulawulwa sisilawuli kude, kwaye ulwazi oluluncedo lunokwabelwana phakathi kwezi zixhobo zihlakaniphile.
Kutheni iinkqubo zasekhaya ezihlakaniphile zisebenzisa iimodyuli zeBluetooth?
Izinto ezilungileyo zokusebenzisa iimodyuli zamandla aphantsi eBluetooth:
1. Ukusetyenziswa kwamandla aphantsi kunye nesantya sokuhambisa ngokukhawuleza
Inqaku lepakethi yedatha emfutshane yeBluetooth sisiseko seempawu zayo zetekhnoloji yamandla aphantsi, izinga lothumelo linokufikelela kwi-1Mb/s, kwaye lonke uqhagamshelo lusebenzisa imowudi yokusezela ekumgangatho ophantsi ukufezekisa umjikelo womthwalo ophantsi kakhulu. I-
2. Ixesha lokuseka uqhagamshelwano lifutshane
Kuthatha kuphela i-3ms emfutshane ukuba inkqubo yesicelo seBluetooth ukuvula nokuseka uqhagamshelwano. Ngexesha elifanayo, inokugqiba ukuhanjiswa kwedatha evunyiweyo kwisantya sothumelo se-milliseconds eziliqela kwaye ngokukhawuleza uvale uxhumano. I-
3. Uzinzo oluhle
Itekhnoloji yamandla aphantsi eBluetooth isebenzisa i-24-bit cyclic ubhaqo wokuphindaphinda ukuqinisekisa ukuzinza okukhulu kwazo zonke iipakethi xa ziphazamisekile. I-
4. Ukhuseleko oluphezulu
Itekhnoloji yofihlo epheleleyo ye-CCM ye-AES-128 ibonelela ngokufihlwa okuphezulu kunye nokuqinisekiswa kweepakethi zedatha.
5. Izixhobo ezininzi ezihambelanayo
IBluetooth 5.0 iyahambelana jikelele phantse kuzo zonke izixhobo zedijithali, ivumela unxibelelwano olungenazingcingo phakathi kwezixhobo ezahlukeneyo zedijithali.
Xa kuthelekiswa nezinye iimodyuli, imodyuli yebluetooth inenzuzo ebalaseleyo yokuba imodyuli yebluetooth ithandwa kakhulu kwisixhobo se-terminal, esenza ukusetyenziswa kwemodyuli yebluetooth kwinkqubo yasekhaya ehlakaniphile ngakumbi, imodyuli yebluetooth inokusetyenziswa kwamandla aphantsi, ukuhanjiswa ngokukhawuleza. kunye nomgama omde Kwaye ezinye iimpawu yi-icing kwikhekhe ukwenzela ukusetyenziswa kweteknoloji yeBluetooth kwiinkqubo zasekhaya ezihlakaniphile.
Njengengcali umenzi wemodyuli yeBluetooth , Iimodyuli ze-Joinet ze-BLE zenzelwe izixhobo eziphantsi kwamandla, njengezinzwa, i-fitness trackers kunye nezinye izixhobo ze-IoT ezifuna ukusetyenziswa kwamandla aphantsi kunye nobomi obude bebhetri. Kule minyaka, i-Joinet yenze inkqubela phambili enkulu ekuphuhliseni iimodyuli ze-BLE / iimodyuli zeBluetooth.
