Yakareba Range Drone Vhidhiyo Transmitter ndeye chaiyo uye nekukurumidza kufambisa iyo yakazara HD yedhijitari vhidhiyo feed kubva kune imwe nzvimbo kuenda kune imwe.Vhidhiyo yekubatanidza chikamu chakakosha cheUAV.Iyo isina waya yemagetsi yekufambisa mudziyo inoshandisa imwe tekinoroji kutumira zvisina waya vhidhiyo yakatorwa nekamera pane-saiti UAV kune kure kumashure munguva chaiyo.Naizvozvo, theUAV vhidhiyo transmitterinonziwo "maziso" eUAV.
Kune top 5technologiesyeUAV Airborne Vhidhiyo Transmitters:
1. OFDM
Nehunyanzvi, iyo inonyanya kushandiswa tekinoroji yekutapurirana pane drones ndeye OFDM, rudzi rwe-multi-carrier modulation, iyo inonyanya kukodzera kumhanyisa data data.OFDM ine zvakawanda zvakanaka, semuenzaniso:
● Nhamba yakawanda ye data inogonawo kutumirwa pasi pe bandwidth yakamanikana.
● Ramba kudzima nguva zhinji kana kukanganiswa nenarrowband.
Nekudaro, OFDM zvakare ine zvayakaipira:
(1) Mutakuri frequency offset
(2) Inonyatsonzwa kune ruzha rwechikamu uye mutakuri frequency offset
(3) Peak-to-average reshiyo yakati wandei.
2. COFDM
COFDM ine kodhi OFDM.Iyo inowedzera imwe chiteshi coding (kunyanya kuwedzera kukanganisa kugadzirisa uye kupindirana) pamberi peOFDM modulation kuvandudza kuvimbika kweiyo system.Musiyano uripo pakati peCOFDM neOFDM ndewekuti makodhi ekugadzirisa kukanganisa uye nguva dzevarindi dzinowedzerwa pamberi pe orthogonal modulation kuti kufambisa kwemasaini kushande.
OFDM inonyanya kushandiswa muLTE (4G), WIFI uye mamwe masisitimu ekushandisa.
COFDM parizvinozvakanyanyazvakakodzerateknolojiayeUAV yakareba-kurevhidhiyo uyekutumira data.Pane zvinotevera 4 zvinhu:
● Iyo bandwidth ndeyehighzvakakwananokutiHD vhidhiyo kutapurirana.
● Nhepfenyuro yekufambisa.Kana iyo yekugamuchira michina inowedzerwa kumagumo epasi, iyo yepamusoro yechiteshi haizowedzerwe.
● Mamiriro ekutumira masaini akaoma.The multipath effectsure thekuendesa kure-kure vhidhiyo.Semuyenzaniso.,150km drone vhidhiyo uye data downlink.
● Kuti zvive nyore kushanda kweUAV, chiratidzo chekufambisa hachigoni kuva nehutungamiri hwakasimba, uye kureba kwekufambisa kunogona kuwedzerwa nekuwedzera simba rekufambisa kuwedzera S / N yeanogamuchira.
3. Wifi
Kufambiswa kweWiFi ndiyo inonyanya kushandiswa tekinoroji yekudhura-inoshandaUAV data transmission.Nekudaro, nekuti WiFi ine zvakawanda zvehunyanzvi zvisingakwanisi uye haigone kugadziridzwa, uye vagadziri vazhinji vanoshandisa mhinduro kuivaka zvakananga.Naizvozvo, zvipingamupinyi zvaro zvakare zvakatanhamara, senge:
● Chip design format haigoni kuchinjwa
● Tekinoroji yakanyanya kusimba
● Kupindira kwekugadzirisa mazano haisi nguva chaiyo
● Kushandiswa kwechiteshi kwakaderera, nezvimwewo.
4.Analogi Vhidhiyo Tkushambadzira Technology
Mamwe maUAV asina gimbal makamera anogona kushandisa analog chiratidzo chekufambisa tekinoroji.
Iko kunenge kusiri kunonoka mukufambiswa kweanalog vhidhiyo, uye chimwe chimiro kana muganhu wasvika, iyo skrini haizongoerekana yaoma kana iyo yese.vhidhiyozvachose tarirass.
Analog vhidhiyo kutapurirana zvakare inzira imwe-yenzira yekufambisa tekinoroji, iyo yakati fanane nekufambiswa kweanalog TV nhepfenyuro masaini masaini edhijitari eTV asati aoneka.Kana chiratidzo chava kupera simba, chidzitiro chechando chinobuda, izvowarnsmutyairi wendege kugadzirisa mafambiro endege kana kudzokera shure.
5. LightbridgeTechnology
Lightbridgetechnology inoshandisa imwe-nzira yekufambisa data data yakafanana neiyo data yekufambisa fomu yeyepamusoro-inokwira TV nhepfenyuro shongwe.
Mhedziso
Iyo yakanyanya tekinoroji tekinoroji yehurefu dhizaini vhidhiyo transmitter ndeyeCOFDM.
WithCOFDMtekinoroji kuvandudza, kune akawanda uye akawanda asina munhu motaskushandira vanhu munzvimbo dzakasiyananzvimbo yakaita semepu, ongororo, kufamba-famba kwenguva refu, izvo zvine njodzi kana kudhurira nguva yakawandisa pabasa.Nemotokari dzisina munhu, basa rinogona kupedzwa zvakakwirira zvinobudirira.
