Isebenza njani iModyuli yeBluetooth?

Ngoku uphuhliso olukhawulezayo lwe-Intanethi, i-Intanethi yeZinto nayo ihlala iqhubela phambili ukuzisa uncedo olukhulu kubomi babantu. Namhlanje, iimveliso ezininzi ze-IoT, ezinje ngabalawuli be-LED kunye nezibane ezihlakaniphile, zineemodyuli zeBluetooth, ngoko isebenza njani imodyuli yeBluetooth?

Yintoni imodyuli yeBluetooth

Imodyuli yeBluetooth sisixhobo esikwaziyo ukunxibelelana ngocingo olufutshane phakathi kwezixhobo zombane. Iqhele ukusetyenziswa ukwenza unxibelelwano phakathi kwezixhobo ezinjengee-smartphones, iilaptops, ii-headsets kunye nezixhobo ze-IoT. Imodyuli yeBluetooth isebenza ngokusekwe kumgangatho wobuchwephesha obungenazingcingo obubizwa ngokuba yiBluetooth, eyenzelwe amandla aphantsi, unxibelelwano olufutshane.

Isebenza njani imodyuli yebluetooth

Umgaqo osebenzayo wemodyuli yeBluetooth kukusebenzisa isixhobo seBluetooth kunye nerediyo ukuxhuma ifowuni ephathwayo kunye nekhompyuter ukuhambisa idatha. Iimveliso zeBluetooth ziquka iimodyuli zeBluetooth, iirediyo zeBluetooth kunye nesoftware. Xa izixhobo ezimbini zifuna ukudibanisa kunye nokutshintshiselana omnye nomnye, kufuneka zidibaniswe. Ipakethi yedatha ithunyelwa kwaye ipakethe yedatha ifunyenwe kwitshaneli enye, kwaye emva kokudluliselwa, kuyimfuneko ukuqhubeka nokusebenza kwelinye ishaneli. Ubuninzi bayo buphezulu kakhulu, ngoko ungakhathazeki malunga nokhuseleko lwedatha.

Umgaqo wokusebenza wemodyuli yeBluetooth umi ngolu hlobo lulandelayo:

1. Umgangatho wobuchwepheshe beBluetooth: Itekhnoloji yeBluetooth isebenza ngokusekwe kwiseti ethile yemithetho kunye neeprothokholi ezichazwe yiBluetooth Special Interest Group (SIG). Ezi prothokholi zichaza ukuba izixhobo kufuneka zinxibelelane njani, ziseke uqhagamshelo kunye notshintshiselwano lwedatha.

2. I-Frequency Hopping Spread Spectrum (FHSS): Unxibelelwano lweBluetooth lusebenzisa iFrequency Hopping Spread Spectrum (FHSS) ukuphepha ukuphazamiseka kwezinye izixhobo ezingenazingcingo ezisebenza kwibhendi yefrikhwensi efanayo. Izixhobo zeBluetooth zitsibela phakathi kweefrikhwensi ezininzi ngaphakathi kwe-2.4 GHz ISM (Iindustrial, iNzululwazi, neyoNyango) band ukunciphisa uphazamiseko olunokwenzeka.

3. Indima yesixhobo: Kunxibelelwano lweBluetooth, isixhobo sidlala indima ethile: isixhobo esiyintloko kunye nesixhobo sekhoboka. Isixhobo esiyintloko siqalisa kwaye silawula uxhulumaniso, ngelixa isixhobo sekhoboka siphendula izicelo zenkosi. Le ngcamango ivumela ukusebenzisana kwesixhobo esifana nesinye ukuya kwesinye okanye esinye ukuya kwabaninzi.

4. Ukubhanqa kunye nokudibanisa: Izixhobo zihlala zihamba ngenkqubo yokudibanisa ngaphambi kokuba zinxibelelane. Ngexesha lenkqubo yokudibanisa, izixhobo zitshintshisa izitshixo zokhuseleko, kwaye ukuba ziphumelele, ziseka uxhumano oluthembekileyo. Le nkqubo inceda ekuqinisekiseni ukuba izixhobo ezigunyazisiweyo kuphela ziyakwazi ukunxibelelana.

5. Ukusekwa koQhagamshelwano: Emva kokubhanqa, izixhobo zinokuseka uqhagamshelo xa ziphakathi komnye nomnye. Isixhobo esiyintloko siqalisa uxhulumaniso kwaye isixhobo sekhoboka siyaphendula. Izixhobo zithethathethana ngeeparamitha ezifana nezinga ledatha kunye nokusetyenziswa kwamandla ngexesha lokuseta uqhagamshelo.

6. Utshintshiselwano lwedatha: Emva kokuba uxhumano lusekiwe, izixhobo zinokutshintshisa idatha. IBluetooth ixhasa iiprofayili ezahlukeneyo kunye neenkonzo ezichaza iindidi zedatha ezinokutshintshwa. Umzekelo, iprofayili engenazandla ivumela unxibelelwano phakathi kwefowuni kunye ne-headset engenazandla, ngelixa iprofayili yomsindo / yevidiyo elawulwa kude ivumela ukulawula izixhobo ze-audiovisual.

7. Iipakethi zedatha: Idatha iyatshintshwa ngohlobo lweepakethi zedatha. Ipakethi nganye iqulethe ulwazi olufana nomthwalo wedatha, iikhowudi zokujonga iimpazamo, kunye nolwazi longqamaniso. Ezi pakethi zedatha zithunyelwa ngamaza erediyo, ukuqinisekisa unxibelelwano oluthembekileyo nolungenazimpazamo.

8. Ulawulo lwamandla: IBluetooth yenzelwe unxibelelwano lwamandla aphantsi, iyenza ilungele izixhobo ezisebenza ngebhetri. Izixhobo zeBluetooth zisebenzisa iindlela ezahlukeneyo zokonga umbane, ezinjengokunciphisa uthumelo lwamandla kunye nokusebenzisa iindlela zokulala xa zingathumeli idatha.

9. Ukhuseleko: IBluetooth ineempawu zokhuseleko zokukhusela idatha ngexesha lothumelo. Uguqulelo oluntsonkothileyo kunye nokuqinisekiswa kusetyenziselwa ukuqinisekisa ukuba idatha etshintshiweyo phakathi kwezixhobo ihlala iyimfihlo kwaye ikhuselekile.

Ungayikhetha njani imodyuli yeBluetooth

Kweli nqanaba, itekhnoloji yeBluetooth sele ingene kuzo zonke iinkalo zobomi. Iimveliso zeshishini zibandakanya izitshixo zocango ezikrelekrele, iintambo zokukhanya ezikrelekrele, imivalo yokukhanya, imidiza ye-elektroniki, ulawulo oluzenzekelayo lwemizi-mveliso kunye phantse nazo zonke izixhobo ezinokucingeleka. Kodwa kubathengi, eyona ilungileyo ifanelekile kwiimveliso zabo, kwaye lolona khetho lulumkileyo ukukhetha ngokweemfuno zabo.

1. Imodyuli yeBluetooth inoxanduva lokuguqula idatha efunyenwe kwi-serial port ibe kwiprotocol yeBluetooth kwaye iyithumele kwisixhobo seBluetooth selinye iqela, kunye nokuguqula ipakethi yedatha yeBluetooth efunyenwe kwisixhobo seBluetooth selinye iqela ukuya kwidatha yeserial port kwaye ukuyithumela kwisixhobo.

2. Khetha iimodyuli zeBluetooth ezineemodyuli ezisebenzayo ezahlukeneyo ngokweempawu zothumelo. Ukuba isetyenziselwa ukuhambisa idatha, unokukhetha imodyuli ye-point-to-point transparent transparent, kunye nemodyuli ye-point-to-multipoint, njenge-Joint-power low-power module Bluetooth.

3. Khetha ngokwefomu yokupakisha. Kukho iintlobo ezintathu zeemodyuli zeBluetooth: uhlobo lomgca, uhlobo lokunyuka komphezulu kunye ne-adapter ye-serial port. Uhlobo lwe-in-line lunezikhonkwane ze-pin, ezihambelana ne-solder yokuqala kunye nokuveliswa kwebhetshi encinci. Kukho iimodyuli ezimbini zeendibano zemodyuli ezakhelwe ngaphakathi nangaphandle. Ukongeza, kukho kwakhona i-adapter ye-serial yeBluetooth ngendlela yoqhagamshelwano lwangaphandle. Xa abathengi bengafanelekanga ukwakha iBluetooth kwisixhobo, banokuqhaga i-adapter ngokuthe ngqo kwi-port ye-serial yesixhobo, kwaye inokusetyenziswa ngokukhawuleza emva kombane.

Ixabiso lesicelo semodyuli yeBluetooth

Iimpawu zokusetyenziswa kwamandla aphantsi kwimodyuli yeBluetooth zivumela imodyuli yeBluetooth ukuba ibonise ixabiso layo elikhethekileyo kumashishini amaninzi amatsha, ukusuka kubathengi be-elektroniki ukuya kwi-elektroniki yonyango, ukusuka kwikhaya elihlakaniphile ukuya kwizicelo zoshishino, iimodyuli zokusetyenziswa kwamandla aphantsi eBluetooth sele zisetyenziswe kwi-Intanethi. Ishishini lentengiso yezinto linendima ebalulekileyo. Isici esinjalo sikwalona khetho lungcono kwiinzwa, kunye ne-Intanethi yeZinto kunye noqhagamshelo lwamafu ngokwemvelo luya kubakho, ukuze izixhobo zeBluetooth zidibanise kuyo yonke into kwaye ziqhagamshele kwi-Intanethi.

Oku ngasentla ngumgaqo osebenzayo wemodyuli yeBluetooth ekwabelwana ngayo yi Joyina imodyuli yeBluetooth  Umvelisi , kunye neminye imixholo yemodyuli yeBluetooth nayo yongezwa kumntu wonke. Ukuba ufuna ukwazi iinkcukacha ezithe vetshe malunga nemodyuli yebluetooth, nceda uqhagamshelane nathi.
