He aha nga hangarau whakawhiti ahokore noa o te waka rererangi kore tangata (UAV)?

Ko te punaha whakawhiti ataata waka rererangi (UAV) he waahanga nui o te waka rererangi kore (UAV).He momoahokoretaputapu tuku.Na etahi hangarau, ko te ataata i mauhia e te kaamera e mauhia ana e te waka rererangi kore tangata (UAV) ka tuku ahokore kiteihana whakahaere whenuai te wa tonu.No reira,harurukaiwhakawhiti ataata ise mohiotia ana ko nga "kanohi" o nga drones.

Na, he aha te mea noa o naianeituku ahokore haruruhangarau?te hangarau auraki o te UAVhe tuku ataatae whai ake neis:

1、OFDMHangarau

Ko te hangarau, ko te hangarau whakawhiti i te nuinga o te waa i runga i te waka rererangi kore ko te OFDM, he rereke te maha o nga kawe kawe, he pai ake te hangarau mo te whakawhiti raraunga tere tere, a he maha nga painga o te OFDM, hei tauira, te nui o nga raraunga. ka taeatukui roto i te hōkaiipurangi whaiti, ka taea te aukati i te ngoikore o te waatea, te pokanoa raneia so i runga.

OFDMtKo te tikanga ka whakamahia ki nga punaha tono penei i te LTE (4G) me te WIFI.

 

2，Hangarau COFDM

COFDM, arā, OFDM waehere,tāpirietahi whakawaehere hongere (tuatahitāpirikei te whakatika hapa me te wehe atu)i muaKo te whakarereketanga OFDM hei whakapai ake i te pono o te punaha.Ko te rereketanga i waenga i te COFDM me te OFDM ko tetāpirite whakawaehere whakatika hapa me te waahi whakamarumaru i mua i te whakarereketanga orthogonal, kia pai ake ai te tuku i te tohu.Ko te COFDM i tenei wa e tino whakamahia ana i roto i te DVB (whakapahotanga ataata mamati), DVB-T, DVB-S, DVB-Cetc.

Ko te hangarau whakarereke COFDM (Orthogonal Frequency Division Multiplexing) ko te hangarau whakawhiti ahokore hou, he tino hangarau kawe-maha, a ka tae te tau ki te 1704 kawe (2K aratau), ara 8K, me te tino mohio ki te tuku raraunga tere (2). -20Mbps) o te "anti-aukati" me te "NLSO tawhiti" i roto i te whakamahi tūturu me te whakaatu pai "rerenga" me te "whakauru" mahi.

Ko te hangarau COFDM he hangarau pai ake te tono ki te ahokoreroa awheHDataatatukunga oharuru.

 

3，Hangarau WIFI

Ko te tuku raraunga o te tuku Wi-Fi me whakatu e te pito tuku me te mutunga whiwhi he tikanga ruru ringa, katahi ka 512 paita ia rahi.Me whakaoti tonu te tukunga o ia paakete raraunga, a ka ngaro tetahi paita i roto i te paatete raraunga kia tukuna ano te katoa o te paatete raraunga, a ka tukuna te paatete raraunga muri i muri i te whiwhinga katoa o te paatete raraunga, ko te te take o te roa o te tuku.

Mo te rerenga haruru, he mea nui te tuku ataata ahokore "wa-waa".Na te paita kotahi, ka pau te wa ki te tuku ano i te paatete katoa.Ko te tuku Wi-Fi he hangarau whakawhiti ahokore tere tere.He tino ngawari ki te tukua whiwhi vIdeo i roto i te waa tuuturu i runga i te kawa TCP/IP, engari ko te rere o nga drones me tino mahi i te waa.Mena ka tukuna ano te putea raraunga, kaore e taea e te kaiwhakahaere te kite i te riipene ataata.Kore i whakaroa te wa-tūturu HD-ataatatukungahearohaehaemokaiwhakahaere.

Ko te hangahanga o te hangarau Wi-Fi kaore i te kii kia whakamahia ki te ahua tono tuku "Air-to-Ground"s.Ko te tikanga ruru ringa-rua e kore e taea te whakaoti i te tawhiti me tetohengao te tuku ataata UAV, na reira kaore e taea te whakatutuki i nga hiahia o te ataata UAVtutu ututing and te whiwhi.

 

4，Hangarau tuku whakaahua matihiko Lightbridge

Ko te Lightbridge he hangarau honohono korero motuhake i whakawhanakehia e DJI, ka taeatuku720p whakamāramatanga teiteiataatame te whakaatu.Ko te tawhiti ka tae ki te 2 km, neke atu i te 5 kiromita (LOS).

Ko te hangarau Lightbridge e whakamahi ana i te tuku raraunga kotahi-ara, he rite ki te ahua tuku o te pourewa whakaata pouaka whakaata teitei.Ka whakatauritea ki te WIFI, ka taea te whakaiti i teataatate roa o te tuku, ko te 2-3 nga wa i te tawhiti whakawhiti WIFI.Kei te whakamahia te nuinga i roto i nga drones kohi whaiaro penei i te DJI.

 

5，Nga Tikanga Whakawhiti Whakawhiti

Ahakoa kaore he roa o te tairitengararaungatuku, he hangarau tuku tohu kotahi-ara, he ahua rite ki te tuku o nga tohu haapurororaa TV tairitenga i mua i te putanga o nga tohu pouaka whakaata mamati.Ka ngoikore te tohu, ka puta he mata hukarere, he whakatupato kia whakatika te kaiurungi i te huarahi rere, kia rere ranei ki muri, kia tata atu ki te hokinga mai.

Ko te kohi hiko o te tairitengararaungahe tino nui te tuku.I te wa e hiahia ana ki te roatangi, kua nui ake tona mana tuku i te awhe kua tohua.Kua tata te whakakorehia tenei hangarau i roto i te tono a Drone Video Transmitter.

 

Whakarāpopototanga

Ko te tātaritanga e whakaatu ana ko te hangarau OFDM me te hangarau COFDM ko te auraki o te Whakawhiti Drone, me te hangarau COFDM he pai ake.Long Range Drone Video Transmitter he taurite i waenga i te tawhiti me te whakapau hiko, me te hono atu ano ki te maha o nga hangarau whakarereke, penei i te horahanga hihinga hei whakapai ake i te kaha ki te aukati i te pokanoa, te arotautanga hangarau puna korero hongere me teso i runga.
