Umahluko phakathi kwe-IR ekude kunye ne-RF yokulawula okude

UCanzibe 17, 2023

Irimowuthi ye-IR sisixhobo esenzelwe ukusebenzisa izixhobo zombane ezifana neeTV, iiDVD player, kunye neebhokisi zentambo. Itekhnoloji ye-infrared ivumela ukuba ithumele imiqondiso kwisixhobo esisilawulayo. Xa ucofa iqhosha, umyalezo okhowudiweyo uyathunyelwa apho umamkeli awutolika kwaye awuphumeze ngokufanelekileyo.I-IR kwi-wifi converter bahlala beqeshwa kumakhaya nakumashishini ukuphatha uluhlu lwezixhobo zombane.


Izilawuli ezikude zikanomathotholo (RF) zinika enye iremowuthi ye-infrared (IR) yokulawula izixhobo zombane. Kuba besebenzisa amaza erediyo endaweni yokukhanya, banokusebenza ngeendonga kunye nemiqobo, kwaye banokuqhutywa ukusuka kude. Ngelixa zibiza kakhulu kwaye zintsonkothile kune-IR ezikude, zihlala zisetyenziswa kwiinkqubo ezizisebenzelayo zasekhaya zokulawula izixhobo ezininzi ukusuka kwindawo enye.


Umahluko phakathi kwe-IR ekude kunye ne-RF yokulawula okude

I-RF imele amaza eRadio Frequency aqala kwi-3 KHz ukuya kwi-300 GHz kwisikali samaza. Amaza e-infrared aqala kwi-300 GHz ukuya kwi-400 THz kwisikali samaza. I-wavelength ye-infrared iphakathi kwe-700 nanometers kunye ne-1 millimeters. Izixhobo zolawulo olukude zidla ngokunikwa amandla yi-IR (Infrared) okanye iRF frequency. Zombini ulawulo olukude lusetyenziselwa usetyenziso olufanayo lokulawula izixhobo ezikude, ubukhulu becala oomabonakude. Makhe sihlolisise umahluko phakathi kwe-IR kunye ne-RF yolawulo olukude.


Kuba ulawulo olukude lweRF luneenzuzo ezininzi ngaphezulu kolawulo olukude lwe-IR kunye nokulungela kokutshintsha ii-IR LEDs ngee-RF transmitters kunye nabamkeli be-IR nabamkeli beRF, uninzi lolawulo olukude lwe-IR luthatyathelwe indawo lulawulo olukude lweRF. Nangona kunjalo, i-hardware ye-RF ithathwa njengobunzima kune-IR hardware. Ngoko ke kuxhomekeke kwizicelo ukukhetha phakathi kwe-IR ne-RF ekude.


Ulawulo olukude lwe-infrared (IR) luthumela ukukhanya okuphantsi kwesantya ukuya kwii-30 ezinyaweni kwaye kufuna umgca othe ngqo wokujonga ukusebenza.

Unako ukuqondair rf converter ngokuzithelekisa nezibane. Ukhomba isibane kwicala ofuna ukuba sikhanyise ngalo. Nantoni na engaphandle kwaloo mtha wokukhanya imnyama. Ukuze iirimowuthi ze-IR zisebenze ngokufanelekileyo, kufuneka ukwazi ukuzikhomba ngqo kwiyunithi ofuna ukuyilawula. Uninzi lwethu luye lwafumanisa ukuba ii-remote ze-IR zisilela njani xa inja ihleli phambi kweTV kwaye asikwazi ukutshintsha itshaneli de ihambe.


Unokuvula ucango lwegaraji yakho kwelinye igumbi ngenxa yokuba iirimowuthi zerediyo (RF) azifuni umgca wokubona ukuze utshintshe. Nangona ucango lwegaraji luvaliwe kwaye ungaphandle, usenakho ukuvula umnyango ngaphandle ngaphandle kokuba nomgca othe ngqo wokujonga kumamkeli. Nokuba umamkeli uthintelwe ziindonga okanye eminye imiqobo, iRF ekude isenokunxibelelana nayo.


Ungabeka izixhobo zakho ze-AV emva kweengcango eziqinileyo, iikhabhathi, okanye kwelinye igumbi kwaye usenolawulo olupheleleyo lokusebenza kwayo kunye neRF ekude. Kuba isebenzisa amaza kanomathotholo endaweni yelayini yokubona, akunyanzelekanga ukuba ukhombe ukude kwisixhobo ngokuthe ngqo.


Ulawulo olukude lwe-IR kunye nolawulo olukude lweRF zombini zisebenzisa injongo enye yokulawula izixhobo zombane, kodwa zisebenzisa iindlela ezahlukeneyo zokuhambisa imiqondiso. Nazi ezinye zeeyantlukwano eziphambili phakathi kwezi zimbini:


Indlela yothumelo: Irimowuthi ze-IR zisebenzisa ukukhanya kwe-infrared ukuthumela iimpawu, ngelixa iirimowuthi zeRF zisebenzisa amaza erediyo.


Uluhlu: Irimowuthi ze-IR zihlala zinoluhlu olufutshane kuneerimothi zeRF. Irimowuthi ze-IR zisebenza ngcono xa isixhobo silawulwa siphakathi kweemitha ezimbalwa ukusuka kwindawo ekude, ngelixa iirimowuthi zeRF zinokusebenza ukusuka kumgama omkhulu kakhulu.


Ukuphazamiseka: Iiremote ze-IR zinokuchaphazeleka kukukhanya okuqaqambileyo okanye ukukhanya kwelanga, okunokuphazamisana nokuhanjiswa kwemiqondiso. Irimowuthi zeRF azibikho lula kukuphazamiseka.


Umgca wokubonwayo: Irimowuthi ze-IR zifuna umgca ocacileyo wokubonwa phakathi kwendawo ekude kunye nesixhobo esilawulwayo, ngelixa iirimowuthi zeRF zinokusebenza ngeendonga kunye neminye imiqobo.


Ukuntsokotha kunye neendleko: iirimothi zeRF zintsonkothe ​​kwaye zibiza kakhulu kuneerimothi ze-IR, ngenxa yobuchwepheshe obongezelelweyo obufunekayo ukusasaza imiqondiso ngamaza erediyo.


Ekugqibeleni, ukhetho phakathi kwe-IR ekude kunye ne-RF ekude kuya kuxhomekeka kwiimfuno zakho kunye nezinto ozikhethayo. Ukuba ufuna ukulawula izixhobo ukusuka kude okanye ngeendonga, irf converter wifi ukuya kude inokuba lolona khetho lungcono. Nangona kunjalo, ukuba ujonge isisombululo esilula nesifikelelekayo solawulo olukude, i-IR ekude inokwanela.Ufuna ukwazi ngakumbi, fowunela Ulawulo olukude, ukhetho lwakhoabavelisi be-remote control.
