Mai watsa Bidiyo mai tsayin Range Drone shine don aika daidai da sauri da cikakken ciyarwar bidiyo na dijital HD daga wuri guda zuwa wani.Haɗin bidiyo wani muhimmin sashi ne na UAV.Na'urar watsawa ta lantarki ce mara igiyar waya wacce ke amfani da wasu fasaha don watsa bidiyon da kyamarar ta ɗauka akan UAV na kan layi zuwa bayan nesa a ainihin lokacin.Saboda haka, daUAV mai watsa bidiyokuma ana kiranta "idanun" na UAV.
Akwai saman 5fasahainanaUAV Masu watsa Bidiyon Jirgin Sama:
1. OFDM
A fasaha, fasahar watsawa da aka fi amfani da ita a kan jirage marasa matuka ita ce OFDM, nau'in nau'in nau'in nau'in jigilar kaya, wanda ya fi dacewa da watsa bayanai masu sauri.OFDM yana da fa'idodi da yawa, misali:
● Hakanan za'a iya aika bayanai masu yawa a ƙarƙashin kunkuntar bandwidth.
● Tsaya mitar zaɓaɓɓen tsangwama ko tsangwama.
Koyaya, OFDM kuma tana da rashin amfani:
(1) Mitar mai ɗaukar kaya
(2) Mai matukar kulawa ga hayaniyar lokaci da mitar mai ɗaukar kaya
(3) Matsakaicin ganiya-zuwa-matsakaici yana da girma.
2. COFDM
COFDM mai lamba OFDM.Yana ƙara wasu tashoshi coding (yafi ƙara gyara kuskure da interleaving) kafin OFDM modulation don inganta amincin tsarin.Bambanci tsakanin COFDM da OFDM shine cewa ana ƙara lambobin gyaran kurakurai da tazara na gadi kafin daidaitawa na orthogonal don sa watsa siginar ya fi tasiri.
Ana amfani da OFDM galibi a cikin LTE (4G), WIFI da sauran tsarin aikace-aikacen.
COFDM a halin yanzumafi yawandacefasahadon UAV mai nisabidiyo kumawatsa bayanai.Akwai abubuwa guda 4 kamar haka:
● bandwidth shinebabbaisadominHD watsa bidiyo.
● Watsa shirye-shirye.Lokacin da aka ƙara kayan aiki a ƙarshen ƙasa, ba za a ƙara yawan tashar tashar ba.
● Yanayin watsa sigina yana da rikitarwa.Tasirin multipathtabbatar dawatsa bidiyo mai nisa.Misali.,150km drone bidiyo da bayanai downlink.
● Don sauƙaƙe aikin UAV, siginar watsawa ba zai iya samun karfin jagoranci ba, kuma ana iya ƙara yawan watsawa ta hanyar ƙara ƙarfin watsawa don ƙara S / N na mai karɓa.
3. Wifi
Watsawar WiFi ita ce fasahar da aka fi amfani da ita don tsadar farashiUAV watsa bayanai.Koyaya, saboda WiFi yana da ƙarancin fasaha da yawa kuma ba za a iya gyara shi ba, kuma masana'antun da yawa suna amfani da mafita don gina shi kai tsaye.Don haka illolinsa ma sun shahara sosai, kamar:
● Ba za a iya canza tsarin ƙirar guntu ba
● Fasaha ta fi ƙarfi
● Dabarun sarrafa tsoma baki ba lokaci ba ne
● Yin amfani da tashoshi yana da ƙananan ƙananan, da dai sauransu.
4.Analog Video Tfasahar fanshi
Wasu UAVs ba tare da kyamarori na gimbal ba na iya amfani da fasahar watsa siginar analog.
Kusan babu jinkiri a watsa bidiyo na analog, kuma wani fasalin shine lokacin da iyakar nisa ya kai, allon ba zai daskare ba kwatsam ko gaba ɗaya.bidiyogaba daya loss.
Watsawar bidiyo na Analog kuma fasahar watsa sigina ce ta hanya ɗaya, wacce ta ɗan yi kama da watsa siginar watsa shirye-shiryen talabijin na analog kafin siginar TV ɗin dijital ta bayyana.Lokacin da siginar ya yi rauni, allon dusar ƙanƙara zai bayyana, wandagargadismatukin jirgi don daidaita hanyar jirgin ko komawa baya.
5. LightbridgeTilmin halitta
Lightbridgetilmin fasaha yana amfani da watsa bayanan hoto ta hanya ɗaya kama da nau'in watsa bayanai na babban hasumiya watsa shirye-shiryen talabijin.
Kammalawa
Mafi ci gaba da fasaha na dogon zangon drone video watsa shi neCOFDM.
Tare daCOFDMci gaban fasaha, ana samun ƙarin abin hawa mara matukishidima ga mutane daban-dabanfilin kamar taswira, bincike, sintiri na dogon zango, waɗanda ke da haɗari ko tsadar lokaci mai yawa ga aiki.Tare da motoci marasa matuka, ana iya kammala aikin sosai yadda ya kamata.
