Uyini umehluko phakathi kwe-IR vs RF?

I-infrared isifushanisiwe njenge-IR. Kuwuhlobo lwemisebe kagesi enamaza amaza amade kunokukhanya okubonakalayo kodwa mafushane kunamaza omsakazo. Ivame ukusetshenziselwa ukuxhumana okungenantambo ngoba amasignali e-infrared angase alethwe futhi amukelwe kalula kusetshenziswa ama-IR diode. Isibonelo, i-infrared (IR) isetshenziswa kakhulu ukulawula okukude kwemishini kagesi efana nomabonakude nezidlali ze-DVD. Ingasetshenziselwa futhi ukushisa, ukomisa, ukuzwa, kanye ne-spectroscopy, phakathi kwezinye izinto.

I-Radio Frequency isifushanisiwe njenge-RF. Kubhekiselwa ezinhlobonhlobo zamafrikhwensi kagesi ngokuvamile asetshenziselwa ukuxhumana okungenantambo. Lokhu kuhlanganisa amaza asuka ku-3 kHz kuye ku-300 GHz. Ngokushintsha imvamisa, ubukhulu, kanye nesigaba segagasi elithwalayo, amasiginali e-RF angahambisa imininingwane emabanga amade. Izinhlelo eziningi zisebenzisa ubuchwepheshe be-RF, okuhlanganisa ezokuxhumana, ukusakaza, amasistimu e-radar, ukuxhumana ngesathelayithi, kanye nenethiwekhi engenantambo. Izithutha zomsakazo kanye nabamukeli, amarutha e-WiFi, omakhalekhukhwini, namagajethi e-GPS konke kuyizibonelo zemishini ye-RF.

Kokubili i-IR (Infrared) ne-RF (Radio Frequency) isetshenziswa kabanzi ekuxhumaneni okungenantambo, kodwa kunomehluko omkhulu:
1. Ububanzi: I-RF inobubanzi obukhulu kune-infrared. Ukudluliswa kwe-RF kungadlula ezindongeni, kuyilapho amasignali e-infrared engakwazi.
2. Ulayini wokubuka: Ama-infrared transmissions adinga umugqa ocacile wokubona phakathi kwesithumeli nomamukeli, kodwa amasignali amafrikhwensi omsakazo angageleza ngezithiyo.
3. Ukuphazamisa: Ukuphazamiseka kwamanye amadivaysi angenawaya esifundeni kungaphazamisa amasignali e-RF, nakuba ukuphazamiseka kwamasignali e-IR kungavamile.
4. Umkhawulokudonsa: Ngenxa yokuthi i-RF inomkhawulokudonsa omkhulu kune-IR, ingathwala idatha eyengeziwe ngenani elisheshayo.
5. Ukusetshenziswa kwamandla: Ngenxa yokuthi i-IR idla amandla amancane kune-RF, ifaneleka kangcono kumadivayisi aphathekayo njengezilawuli kude.

Kafushane, i-IR iphakeme ekuxhumaneni kwebanga elifushane, lomugqa wokubona, kanti i-RF ingcono kububanzi obude, ukuxhumana okungena izithiyo.

Xhumana nathifuthi singabelana ngolwazi olwengeziwe mayelana nezibani ze-strip ze-LED.
