Izinto ezilishumi ekufuneka uziqwalasele xa uthenga iModyuli yeBluetooth
Nangona ngoku kukho iimodyuli ezininzi zeBluetooth zobukhulu obahlukeneyo kunye neentlobo kwiimarike onokukhetha kuzo, abaninzi abavelisi bezixhobo ezihlakaniphile bakhathazwa yindlela yokukhetha imodyuli yeBluetooth efanelekileyo kwiimveliso zabo. Enyanisweni, xa kuthengwa a Imodyuli yeBluetooth , ubukhulu becala kuxhomekeke kwimveliso oyivelisayo kunye nemeko esetyenziswa kuyo.
Apha ngezantsi, i-Joinet ishwankathela izinto ezilishumi eziphezulu ekufuneka uzithathele ingqalelo xa uthenga iimodyuli zeBluetooth kwireferensi yoninzi lwabavelisi besixhobo se-IoT.
Izinto ekufuneka uziqwalasele xa uthenga imodyuli yeBluetooth
1. I-Chip
Itshiphu imisela amandla ekhompyutha emodyuli yeBluetooth. Ngaphandle kwe "core" eyomeleleyo, ukusebenza kwemodyuli yeBluetooth ayinakuqinisekiswa. Ukuba ukhetha imodyuli yeBluetooth enamandla aphantsi, iichips ezingcono ziquka iNordic, Ti, njl.
2. Ukusetyenziswa kwamanzi
IBluetooth yahlulwe ngokweBluetooth yemveli kunye neBluetooth enamandla aphantsi. Izixhobo ezihlakaniphile ezisebenzisa iimodyuli zeBluetooth zemveli zinokuqhawuka rhoqo kwaye zifuna ukudityaniswa okuphindaphindiweyo, kwaye ibhetri iya kuphelelwa ngokukhawuleza. Izixhobo ezihlakaniphile ezisebenzisa iimodyuli zeBluetooth ezinamandla aphantsi zifuna kuphela ukubhanqa enye. Ibhetri yeqhosha elinye linokuqhuba ixesha elide. Ke ngoko, ukuba usebenzisa isixhobo esinebhetri esine-wireless smart, kungcono ukusebenzisa i-Bluetooth 5.0/4.2/4.0 imodyuli yeBluetooth enamandla aphantsi ukuqinisekisa imveliso.’ubomi bebhetri.
3. Umxholo wothumelo
Imodyuli yeBluetooth inokusasaza idatha kunye nolwazi lwelizwi ngaphandle kwamacingo. Yahlulwe kwimodyuli yedatha yeBluetooth kunye nemodyuli yezwi yeBluetooth ngokomsebenzi wayo. Imodyuli yedatha yeBluetooth isetyenziselwa ukuhanjiswa kwedatha, kwaye ifanelekile kulwazi kunye nokuhanjiswa kwedatha kwiindawo zikawonkewonke ezinetrafikhi ephezulu njengemiboniso, izitishi, izibhedlele, izikwere, njl.; Imodyuli yelizwi yeBluetooth inokusasaza ulwazi lwelizwi kwaye ilungele unxibelelwano phakathi kweeselfowuni zeBluetooth kunye neeseti zeBluetooth. Ukuhanjiswa kolwazi lwelizwi.
4. Izinga losulelo
Xa ukhetha imodyuli yeBluetooth, kufuneka ucace malunga nokusetyenziswa kwemodyuli yeBluetooth, kwaye usebenzise izinga lokudluliselwa kwedatha elifunekayo phantsi kweemeko zokusebenza njengenqobo yokukhetha. Emva kwayo yonke loo nto, ireyithi yedatha efunekayo ukuhambisa umculo okumgangatho ophezulu kwii-headphones yahlukile kwi-monitor ye-heartbeat. Amazinga edatha afunekayo ahluka ngokubanzi.
5. Umgama wothumelo
Abavelisi besixhobo se-IoT kufuneka baqonde indawo apho iimveliso zabo zisetyenziswa khona kwaye ingaba iimfuno zabo zokuhambisa ngaphandle kwamacingo ziphezulu na. Kwiimveliso ezingenazintambo ezingadingi umgama ophezulu wokuhanjiswa kwamacingo, njengeempuku ezingenazintambo, ii-headphones ezingenazintambo, kunye nolawulo olukude, unokukhetha iimodyuli zeBluetooth kunye nomgama wothumelo ongaphezu kweemitha ezili-10; kwiimveliso ezingadingi umgama wothumelo olungenacingo oluphezulu, njengezibane zokuhombisa zeRGB, unokukhetha Umgama wothumelo ungaphezulu kweemitha ezingama-50.
6. Ifomu yokupakisha
Kukho iintlobo ezintathu zeemodyuli zeBluetooth: uhlobo lwe-plug-in ngqo, uhlobo lwe-surface-mount kunye ne-serial port adapter. Uhlobo lweplagi oluthe ngqo lunezikhonkwane, olulungele ukuthengiswa kwangaphambili kwaye lufanelekile kwimveliso encinci yebhetshi; imodyuli ephakanyiswe phezulu isebenzisa iipads ze-semi-circular njengezikhonkwane, ezifanelekileyo kwimveliso yokuthengiswa kwe-reflow yomthamo omkhulu kubathwali abancinci; i-adaptha ye-serial yeBluetooth isetyenziswa Xa kungafanelekanga ukwakha iBluetooth kwisixhobo, ungayiplaga ngokuthe ngqo kwi-nine-pin serial port yesixhobo kwaye ingasetyenziswa ngoko nangoko emva kokukhanyisa.
7. Ujongano
Ngokuxhomekeke kwiimfuno zojongano lwemisebenzi ethile ephunyeziweyo, ujongano lwemodyuli yeBluetooth yahlulahlulwe yaba ziindawo ezilandelelanayo, ujongano lwe-USB, izibuko zedijithali ze-IO, izibuko ze-analog IO, izibuko zeprogram ye-SPI kunye nojongano lwelizwi. Ujongano ngalunye lunokuphumeza imisebenzi eyahlukeneyo ehambelanayo. . Ukuba lugqithiso lwedatha nje, sebenzisa nje ujongano lweserial (inqanaba leTTL).
8. Ubudlelwane benkosi-khoboka
Imodyuli eyintloko inokukhangela ngokusebenzayo kwaye idibanise ezinye iimodyuli zeBluetooth ezinezinga elifanayo okanye elisezantsi lenguqulo yeBluetooth kunayo; imodyuli yekhoboka ilinda ngokuqhubekayo ukuba abanye bakhangele kwaye baqhagamshele, kwaye inguqulo yeBluetooth kufuneka ifane okanye ibe phezulu kuneyayo. Uninzi lwezixhobo ezihlakaniphile kwiimarike zikhetha iimodyuli zekhoboka, ngelixa iimodyuli eziphambili zisetyenziswa ngokubanzi kwizixhobo ezifana neefowuni eziphathwayo ezinokusebenza njengamaziko olawulo.
9. I-antenna
Iimveliso ezahlukeneyo zineemfuno ezahlukeneyo zee-eriyali. Okwangoku, ii-eriyali ezisetyenziswa ngokuqhelekileyo kwiimodyuli zeBluetooth ziquka ii-eriyali ze-PCB, ii-eriyali ze-ceramic kunye nee-eriyali ze-IPEX zangaphandle. Ukuba zifakwe ngaphakathi kwendawo yokuhlala yesinyithi, iimodyuli zeBluetooth ezine-IPEX ze-eriyali zangaphandle zikhethwa ngokubanzi.
10. Ukusebenza kweendleko
Ixabiso yeyona nto ixhalabisayo kubenzi bezixhobo ezininzi ze-IoT
I-Joinet iye yabandakanyeka ngokunzulu kwintsimi yeemodyuli ze-Bluetooth zamandla aphantsi iminyaka emininzi. Ngo-2008, yaba ngumthengisi okhethwayo kwiinkampani eziphezulu ezingama-500 zehlabathi. Inomjikelo omfutshane wokugcinwa kwempahla kwaye unokuphendula ngokukhawuleza kwiimfuno ezahlukeneyo zoninzi lwabavelisi bezixhobo. Ikhonkco lobonelelo olukhoyo lwenkampani kunye nemigca yemveliso inokufikelela kwiinzuzo ezicacileyo zexabiso, ukuqinisekisa ukuba uninzi lwabavelisi bezixhobo banokusebenzisa iimodyuli zeBluetooth ezinexabiso eliphantsi, ezinexabiso eliphantsi. Ukongeza kwezi ngqwalasela ezilishumi zingentla, abavelisi besixhobo nabo kufuneka baqonde ubungakanani, ukufumana ubuntununtunu, amandla okuhambisa, iFlash, i-RAM, njl. yemodyuli yeBluetooth xa uthenga imodyuli yeBluetooth.
