I-Long Range Drone Video Transmitter kukusasaza ngokuchanekileyo nangokukhawuleza i-HD epheleleyo yevidiyo yedijithali ukusuka kwindawo ukuya kwenye.Ikhonkco levidiyo liyinxalenye ebalulekileyo ye-UAV.Sisixhobo sokuhambisa i-elektroniki esingenazingcingo esisebenzisa itekhnoloji ethile ukusasaza ngaphandle kwamacingo ividiyo ethathwe yikhamera kwi-UAV ekwisiza ukuya ngasemva okude ngexesha lokwenyani.Ngoko ke, iIsidluliseli sevidiyo ye-UAVikwabizwa ngokuba "ngamehlo" e-UAV.
Kukho i-5 ephezuluiteknolojiEweyeI-UAV Airborne Video Transmitters:
1. OFDM
Ngokobuchwephesha, iteknoloji yosasazo olusetyenziswa kakhulu kwi-drones yi-OFDM, uhlobo lwe-modulation ye-multi-carrier modulation, efanelekileyo kakhulu kwi-high-speed data transmission.I-OFDM ineenzuzo ezininzi, umzekelo:
● Inani elikhulu ledatha lingathunyelwa phantsi kwe-bandwidth emxinwa.
● Kuxhathise ukufiphala okukhethiweyo okanye uphazamiseko lwebhanti emxinwa.
Nangona kunjalo, i-OFDM ikwanazo nezingeloncedo:
(1) I-Carrier frequency offset
(2) Ubuthathaka kakhulu kwingxolo yesigaba kunye ne-carrier frequency offset
(3) Umlinganiselo wencopho-kumndilili uphezulu ngokwentelekiso.
2. COFDM
I-COFDM inekhowudi ye-OFDM.Yongeza ikhowudi ethile yesitishi (ikakhulukazi yongeza ukulungiswa kwempazamo kunye nokushiyana) ngaphambi kokuguqulwa kwe-OFDM ukuphucula ukuthembeka kwenkqubo.Umahluko phakathi kwe-COFDM kunye ne-OFDM kukuba iikhowudi zokulungiswa kweempazamo kunye namaxesha okulinda zongezwa ngaphambi kokuguqulwa kwe-orthogonal ukwenza ukuhanjiswa komqondiso kusebenze ngakumbi.
I-OFDM isetyenziswa kakhulu kwi-LTE (4G), i-WIFI kunye nezinye iinkqubo zesicelo.
I-COFDM okwangokuOkuninziezifanelekileyoiteknolojikumgama omde we-UAVividiyo kwayeukuhanjiswa kwedatha.Kukho ezi zinto zi-4 zilandelayo:
● I-bandwidth yiphezulukonelengenxaUkuhanjiswa kwevidiyo ye-HD.
● Usasazo losasazo.Xa izixhobo zokufumana izixhobo zongezwa ekupheleni komhlaba, i-overhead yetshaneli ayiyi kwandiswa.
● Iimeko zokudluliselwa kwemiqondiso zintsonkothile.Isiphumo seendlela ezininziqinisekisa iukuhanjiswa kwevidiyo kumgama omde.Umzekelo.,I-150km ividiyo yedrone kunye ne-data downlink.
● Ukuze kuququzelelwe ukusebenza kwe-UAV, isignali yokudlulisa ayikwazi ukuba nolwalathiso olunamandla kakhulu, kwaye umgama wokuhambisa unokunyuswa ngokunyusa amandla okuhambisa ukwandisa i-S / N yomamkeli.
3. Wifi
Ugqithiso lwe-WiFi yeyona ndlela isetyenziswayo yetekhnoloji eyonga imaliUkuhanjiswa kwedatha ye-UAV.Nangona kunjalo, ngenxa yokuba i-WiFi inezithintelo ezininzi zobugcisa kwaye ayikwazi ukuguqulwa, kwaye abaninzi abavelisi basebenzisa isisombululo sokuyakha ngokuthe ngqo.Ke ngoko, ukungalungi kwayo kugqame kakhulu, njengale:
● Ifomati yoyilo lwetshiphu ayinakuguqulwa
● Iteknoloji yomelele ngakumbi
● Isicwangciso solawulo longenelelo asiloxesha lokwenyani
● Ukusetyenziswa kwejelo kuphantsi kakhulu, njl.
4.Ividiyo ye-Analog Titeknoloji yorhwebo
Ezinye ii-UAVs ngaphandle kweekhamera ze-gimbal zingasebenzisa iteknoloji yokuhambisa uphawu lwe-analog.
Phantse akukho kulibaziseka kukuhanjiswa kwevidiyo ye-analog, kwaye elinye inqaku kuxa umgama womda ufinyelelwe, isikrini asiyi kukhenkceka ngequbuliso okanye siphelele.ividiyongokupheleleyo nass.
Usasazo lwevidiyo ye-Analog ikwayindlela enye yetekhnoloji yokuhambisa umqondiso, efana kancinane nokuhanjiswa kwemiqondiso yosasazo ye-analog kamabonakude phambi kokuba kuvele imiqondiso yedijithali.Xa uphawu luba buthathaka, isikrini sekhephu siya kuvela, leyolumkisasumqhubi wenqwelomoya alungise indlela yenqwelomoya okanye abuyele umva.
5. I-LightbridgeTiteknoloji
I-LightbridgetI-echnology isebenzisa ukuhanjiswa kwedatha yendlela enye efana nefomu yothumelo lwedatha yenqaba yosasazo yeTV ephezulu.
Ukuqukumbela
Itekhnoloji ephezulu kakhulu yoluhlu olude lokuhambisa ividiyo yedrone yiCOFDM.
NgeCOFDMuphuhliso lobuchwephesha, kukho ngakumbi nangakumbi isithuthi unmannedsukukhonza abantu kwiindawo ezahlukeneyoindawo efana nemephu, uphando, ukujikeleza kuluhlu olude, eziyingozi okanye iindleko zexesha elininzi emsebenzini.Ngezithuthi ezingenabantu, umsebenzi unokugqitywa phezulu ngokufanelekileyo.
