Ungayikhetha njani iModyuli yeBluetooth efanelekileyo?

Njengemodyuli yonxibelelwano olungenazingcingo oluvela kuluhlu olufutshane, i Imodyuli yeBluetooth isetyenziswe ngokubanzi kwiinkalo ezininzi ezibandakanya ikhaya elihlakaniphile, izixhobo zonyango, kunye nokuthengisa okutsha. Ibonelela ngexabiso eliphantsi, amandla aphantsi, kunye nonxibelelwano olungenazingcingo olufutshane, kwaye yenza inethiwekhi yomntu kwindawo yonxibelelwano phakathi kwezixhobo ezisisigxina kunye neselfowuni, ivumela ukwabelana ngemithombo engenamthungo yezixhobo zolwazi ezahlukeneyo kumgama omfutshane. Ekubeni kukho ubungakanani obahlukeneyo kunye neentlobo zeemodyuli zeBluetooth kwimarike, ukhuphiswano lwemarike luqiniswa kwaye ubunzima bokukhetha buyanda. Ke, singakhetha njani imodyuli efanelekileyo yeBluetooth?

Enyanisweni, kungakhathaliseki ukuba luhlobo luni lwemodyuli yeBluetooth, isakhiwo sayo sahluke kakhulu. Unganqwenela ukuhlalutya kwaye uqwalasele kwezi engile zilandelayo:

1. I-Chip: i-chip enamandla isiqinisekiso esinamandla sokusebenza kwemodyuli yeBluetooth.

2. Ubungakanani: Izixhobo zanamhlanje ze-IoT ezihlakaniphile zilandela ubungakanani obuncinci, kwaye isakhiwo secandelo langaphakathi sikwafuna ubuncinci ubungakanani, ngcono.

3. Uzinzo: Namhlanje, iinkqubo ezininzi zineemfuno eziphezulu kunye neziphezulu zokusebenza kakuhle kwezixhobo, ngokukodwa iimodyuli zonxibelelwano kwiinkqubo zoshishino, ezihlawula ingqalelo ekhethekileyo ekuzinzeni nasekubekeni iliso. Inkqubo yokusingatha kufuneka yazi imeko yokusebenza yemodyuli yeBluetooth nangaliphi na ixesha. Ukuba imodyuli yeBluetooth ekumgangatho ophezulu, kufuneka ikwazi ukubonelela ngeempawu zesimo sokusebenza esisebenzayo sangaphakathi nangaphandle ngaxeshanye. Ukongeza, ikwadinga ukubonelela ngemiqondiso eyahlukeneyo efana nolawulo lwekhonkco.

4. Umgama wothumelo: I-Bluetooth yahlulwe ikakhulu ngamanqanaba amabini amandla. Umgama wonxibelelwano osemgangathweni wenqanaba le-1 li-100 yeemitha, kwaye umgama wonxibelelwano osemgangathweni wenqanaba lesi-2 ziimitha ezili-10. Kufuneka kuqatshelwe ukuba amandla kwinqanaba le-1 liphezulu kunenqanaba lesi-2, umgama wonxibelelwano ude, kwaye inqanaba elihambelanayo le-radiation 1 inkulu. Kwisicelo sangempela sezisombululo zeBluetooth, abaphuhlisi kufuneka baqonde indawo ehlala kuyo imveliso kunye nokuba ngaba ukuhanjiswa komgama omde kuyadingeka, ukuze kuqinisekiswe ukuba yeyiphi imodyuli yeBluetooth ihlangabezana neemfuno zokuhanjiswa kwedatha ngokusekelwe kumgama. Kwezinye iimveliso ezingafunekiyo ukuba ziqhutywe kumgama omde, njengeempuku ezingenazingcingo, ii-headsets ezingenazingcingo, njl., sinokukhetha iimodyuli ezinemigama emifutshane yothumelo, njengeemodyuli ezingaphezu kweemitha ezili-10; kwiimveliso ezifuna imigama emide, iimodyuli ezinemigama yokuhanjiswa okukhulu kuneemitha ezingama-50 zinokukhethwa.

5. Ukusetyenziswa kwamanzi: Imodyuli yeBluetooth Low Energy (imodyuli yeBLE) idume ngokusetyenziswa kwamandla aphantsi, kodwa ineendawo ezahlukeneyo zokusebenza, kubandakanya ukusasaza, ukuhanjiswa okuqhubekayo, ubuthongo obunzulu, imeko yokulinda, njl. Ukusetyenziswa kwamandla kwilizwe ngalinye kwahlukile.

6. Iindleko: ixabiso yeyona nto ixhalabisayo yabaninzi abavelisi besixhobo se-IoT. Umenzi wokuqala wemodyuli yeBluetooth unenzuzo ecacileyo yexabiso. Abathengisi abakhethiweyo kufuneka bakwazi ukulawula ngokungqongqo umgangatho weemodyuli, kwaye banikeze ukuthengiswa kwangaphambili kunye nenkxaso yobugcisa emva kokuthengisa. Kukho uluhlu oluqhelekileyo lweemodyuli zokuqinisekisa ukuba iimodyuli zeBluetooth ezingabizi kakhulu, ezingabizi kakhulu ziyafumaneka.

7. Umsebenzi owomeleleyo: imodyuli efanelekileyo yeBluetooth kufuneka ibe nobuchule obuhle bokuchasana nokuphazamiseka, ingasetyenziselwa kwiindawo ezahlukeneyo zokunxibelelana, kwaye inokudibaniswa nezixhobo ezahlukeneyo, kwaye inokudityaniswa nge-synchronously; ukungena okunamandla, imiqondiso yeBluetooth inokungena kwizinto ezininzi ezingezizo ezentsimbi; ukhuseleko lothumelo, ngoguqulelo oluntsonkothileyo kunye ne-decryption algorithms kunye neendlela zokuqinisekisa ukuqinisekisa ukhuseleko losasazo.

Ke, ukuba ufuna ukukhetha imodyuli efanelekileyo yeBluetooth, ungaqala kule miba ingentla, okanye ungakhetha ethembekileyo. umenzi wemodyuli yeBluetooth . Imodyuli yeBluetooth inenzuzo enkulu enokuthi ifakwe ngokukhawuleza. Ukuba kusetyenziswe indlela yokunxibelelana ngeentambo, kuyimfuneko ukumisa iintambo okanye ukumba imisele yentambo ngexesha lokusekwa, elifuna umgudu omkhulu. Ngokwahlukileyo, ukusebenzisa imodyuli yeBluetooth ukuseka imowudi yothumelo lwedatha engenazingcingo kusindisa kakhulu abasebenzi, izixhobo eziphathekayo kunye notyalo-mali.

IJoinet ibigxile kuR&D kunye nokutsha kwintsimi yeemodyuli zeBluetooth zamandla aphantsi iminyaka emininzi. Iimodyuli zeBluetooth eziveliswayo zineenzuzo zesantya sothumelo oluzinzileyo, ukusetyenziswa kwamandla aphantsi, kunye nenkxaso yeeprotocol zonxibelelwano ezininzi. Ziyilelwe izixhobo ezinamandla aphantsi ezifana nezinzwa, iitracker zokuqina, kunye nezinye izixhobo ze-IoT ezifuna ukusetyenziswa kwamandla amancinci kunye nobomi obude bebhetri. Njengomenzi wemodyuli yeBluetooth yobuchwephesha, iJoinet ibonelela abathengi ngeenkonzo zemodyuli zeBLE. Wamkelekile ukuba uqhagamshelane nathi ngeenkcukacha ezithe vetshe malunga nemodyuli yebluetooth.
