Kodi matekinoloje otumiza opanda zingwe a common unmanned air vehicle (UAV) ndi ati?

Makina otumizira mavidiyo a unmanned aerial vehicle (UAV) ndi gawo lofunika kwambiri pagalimoto yosayendetsedwa ndi ndege (UAV).Ndi mtundu waopanda zingwezida zotumizira.Ndi ukadaulo wina, kanema wojambulidwa ndi kamera yonyamulidwa ndi munda wosayendetsedwa ndi ndege (UAV) imatumizidwa popanda zingwemalo owongolera pansimu nthawi yeniyeni.Chifukwa chake,dronechopatsira kanema isamadziwikanso kuti "maso" a drones.

Kotero, ndi chiyani chomwe chiri chofaladrone opanda zingwe kufalaluso?teknoloji yayikulu ya UAVkutumizirana mavidiyo ndizotsatirazis:

1,OFDMNjira

Mwaukadaulo, ukadaulo womwe umagwiritsidwa ntchito kwambiri pakupatsirana pagalimoto yopanda munthu ndi OFDM, yomwe ndi njira yonyamula zonyamulira zambiri, ukadaulo ndioyenera kutumiza mwachangu kwambiri, ndipo OFDM ili ndi zabwino zambiri, mwachitsanzo, kuchuluka kwa data. akhoza kukhalaopatsiranamu narrowband bandiwifi, pafupipafupi kusankha kuzimiririka kapena narrowband kusokoneza akhoza kukanidwandi so pa.

OFDMtechnique imagwiritsidwa ntchito makamaka pamakina ogwiritsira ntchito monga LTE (4G) ndi WIFI.

 

2,Njira ya COFDM

COFDM, mwachitsanzo, OFDM,akuwonjezerama code code ena (makamakaonjezanikukonza zolakwika ndikusiyanitsidwa)kaleKusintha kwa OFDM kuti musinthe kudalirika kwadongosolo.Kusiyana kwa COFDM ndi OFDM ndikoonjezanikuwongolera zolakwika ndi nthawi yoteteza kusanachitike kusinthika kwa orthogonal, kuti chizindikirocho chifalitsidwe bwino.COFDM ikugwiritsidwa ntchito kwambiri mu DVB (kuwulutsa kanema wa digito), DVB-T, DVB-S, DVB-Cndi zina.

The COFDM (Orthogonal Frequency Division Multiplexing) ukadaulo wosinthira ndiukadaulo waposachedwa wopanda zingwe, womwe ndiukadaulo weniweni wonyamula zinthu zambiri, ndipo chiwerengerocho chimafika ku 1704 chonyamulira (2K mode), ngakhale 8K mode, ndikuzindikira kutumizirana mwachangu kwa data (2 -20Mbps) ya "anti-blocking" ndi "NLSO mtunda" pakugwiritsa ntchito kwenikweni ndikuwonetsa bwino "kusokoneza" ndi "kulowa".

Ukadaulo wa COFDM ndiukadaulo wabwinoko womwe umagwiritsidwa ntchito pazingweyaitali osiyanasiyanaHDmakanemakufala kwadrone.

 

3,Njira ya WIFI

Kutumiza kwa data kwa kufala kwa Wi-Fi kumafuna kuti mapeto otumizira ndi olandirawo ayambe kukhazikitsa njira yolumikizirana chanza, ndiyeno kukula kulikonse ndi ma byte 512.Kutumiza kwa paketi iliyonse ya data kuyenera kumalizidwa bwino, ndipo byte imodzi mu paketi ya data imatayika kuti ipangitse kuti paketi yonse ya data itumizidwenso, ndipo paketi yotsatira ya data imafalikira pokhapo pakalandira paketi imodzi ya data, yomwe ndi chifukwa chachikulu chakuchedwa kufalikira.

Pakuwuluka kwa ma drone, kufalitsa mavidiyo opanda zingwe "nthawi yeniyeni" ndikofunikira.Chifukwa cha baiti imodzi, zimatengera nthawi yayitali kutumizanso paketi yonse.Kutumiza kwa Wi-Fi ndiukadaulo wothamanga kwambiri wopanda zingwe.Ndiosavuta kufalitsandi landira video mu nthawi yeniyeni yotengera protocol ya TCP/IP, koma kuwuluka kwa ma drones kumafuna magwiridwe antchito apamwamba kwambiri.Ngati paketi ya data itumizidwanso, wogwiritsa ntchito sangathe kuwona kanema wanthawi yeniyeni.Kanema wa HD wanthawi yeniyeni wosachedwetsakufalandiwotsutsazawoyendetsa.

Kupangidwa kwa ukadaulo wa Wi-Fi sikunapangidwe kuti zizigwiritsidwa ntchito panjira yotumizira "Air-to-Ground"s.Njira ziwiri zogwirirana chanza zimapangitsa kuti zikhale zosatheka kuthetsa mtunda ndikuchedwaKutumiza kwamavidiyo a UAV, kotero sikungakwaniritse zosowa za kanema wa UAVtransmitpa andi kulandira.

 

4,Lightbridge Digital Transmission Technique

Lightbridge ndiukadaulo wapadera wolumikizirana wopangidwa ndi DJI, womwe ungathekufalitsa720p kutanthauzira kwakukulukanemandi chiwonetsero.Mtunda umatha kufika 2 kmndi kuposa 5 km (LOS).

Ukadaulo wa Lightbridge umagwiritsa ntchito njira imodzi yotumizira ma data, yomwe ili ngati mawonekedwe opatsira a nsanja yapamwamba yowulutsira pa TV.Poyerekeza ndi WIFI, imatha kuchepetsakanemakuchedwa kufalitsa, komwe ndi 2-3 nthawi ya WIFI kufala mtunda.Amagwiritsidwa ntchito kwambiri pama drones omwe amamwa anthu ngati DJI.

 

5,Njira Zosamutsa Zoyeserera

Ngakhale pali pafupifupi palibe kuchedwa analogidetakufalitsa, ndiukadaulo wa njira imodzi yotumizira ma siginoloji, omwe ali ngati kufalitsa ma siginecha a TV a analogi asanatulukire ma siginecha a digito.Chizindikirocho chikafooka, padzakhala chinsalu cha chipale chofewa, chochenjeza kuti woyendetsa ndege asinthe kumene akuchokera kapena kuwulukira kumbuyo, pafupi ndi malo obwerera.

Kugwiritsa ntchito mphamvu kwa analogidetakufala ndi kwakukulu kwambiri.Pamene ikufuna kufika nthawi yaitalikulira, mphamvu yake yotumizira yadutsa malire otchulidwa.Ukadaulo uwu watsala pang'ono kuthetsedwa pakugwiritsa ntchito Drone Video Transmitter.

 

Chidule

Kuwunika kukuwonetsa kuti ukadaulo wa OFDM ndi ukadaulo wa COFDM ndizofala kwambiri pa Drone Transmitter, ndipo ukadaulo wa COFDM ndiwotsogola kwambiri.Long Range Drone Video Transmitter ndiyolingana pakati pa mtunda ndi kugwiritsa ntchito mphamvu, ndipo imagwirizananso ndi matekinoloje ambiri osinthira, monga kufalitsa sipekitiramu kuti apititse patsogolo kuthekera kothana ndi kusokoneza, kukhathamiritsa kwaukadaulo wazidziwitso zamakina ndiso pa.
