Monga wopanga akatswirimaulalo amakanema opanda zingwe, Tikubetcha kuti mumafunsidwa pafupipafupi ndi ogwiritsa ntchito: mungakhale nthawi yayitali bwanjiUAV COFDM Video Transmitter or Maulalo a UGVkufika?
Kuti tiyankhe funsoli, tifunikanso zambiri monga kutalika kwa tinyanga tating'ono/zopinga za mtunda, ndi zina zotero. Kugwiritsa ntchito mawayilesi opanda zingwe ndi chinthu chimodzi chokha.M'malo mwake, pokhapokha pofufuza mwatsatanetsatane izi mutha kuyesa mtunda weniweni wa kulumikizana opanda zingwe.Komabe kuunika koteroko kumafuna chidziwitso chochuluka ndi luso lazochitikira.
Blog iyi ipereka njira zoyambira komanso zotsogola zokuthandizani kupanga ziganizo zokhudzana ndi mtunda wolumikizana.
Nazi zinthu zomwe zimakhudza kulankhulana mtunda ndi mphamvu yaWireless Video Transmission System.
1. Mafotokozedwe azinthu zotumizira makanema opanda zingwe
● Mphamvu ya RF: a RF wamkulumphamvu ya chopatsiraakhozakufikiraa yaitalimtunda wolumikizana.
TheapamwambaRF mphamvu, mafunde akutali wailesi akhoza kuyenda.Mgwirizano pakati pa mphamvu yotulutsa ndiopanda zingwemtunda wolankhulana ndi wosiyana kwambiri ndi bwalo, ndiko kunena kuti, mphamvu yotulutsa imawirikiza kawiri, ndipo mtunda wolumikizana ndi wowirikiza muzu wa choyambirira.Mphamvu yotulutsa ndi nthawi 4 yapachiyambi, ndipo mtunda wolankhulana ndi nthawi 2 zapachiyambi.
● Kulandira Chidziwitso: Kuchepetsa kukhudzika kwa kulandila, kumakhala bwino
Kulandira tcheru amatanthauza osachepera mlingo kutimawayilesi olumikizana opanda zingweakhoza kulandira ndi kuzindikira. Pamene amtundandi yaitalindipo mphamvu ya chizindikiro imakhala yofooka kwambirier, m'munsi tilinazowailesihaveubwino wogwira chizindikiro, ndiko kuti, ukhoza kugwira ntchito patali.
2. Ma radiation
Kufalikira kwa mafunde a wailesi ndi chinthu cha electromagnetic field field.Imayenda ngati mafunde amagetsi ndi maginito.
Kodi mafunde a wailesi amafalitsidwa bwanji kuchokera mu mlongoti?:
Kugwiritsiridwa ntchito kwa njira imeneyi pofotokoza kufalikira kwa mafunde a wailesi kukadali kopanda ungwiro. Mwachitsanzo, anthu amafunsabe kuti, "Kodi bwaloli ndi lalikulu bwanji?""Kunja kwa bwalo kuli chiyani?"
Chifukwa chake, kuti timvetsetse bwino za kutulutsa kwa wailesi,timagwiritsa ntchito nyali ya fulorosenti kutengera ma radiation monga pansipa (3).
Bchilungamondi wamphamvumkatikatindi ofooka kumapeto onse awiri, kusonyeza kufalikira kwamphamvu kwa kuwala kochokera ku nyali.Chodabwitsa ichi chikhoza kufananizidwa ndi mlongoti wotumizira opanda zingwe, pomwe mphamvu ya siginecha pakati imakhala yokwera ndipo mphamvu yazizindikiro pamapeto onse awiri ndi yotsika.Kuti's chifukwakutalika kwa unsembe wa mlongoti ndi chinthu chofunika zimakhudza mtunda wolumikizana.
3.Zachilengedwe
Mphamvu za wailesi "zimamasuka" kuchokera ku mlongoti ndikupita kumalo aulere.Pali malo osasunthika amagetsi ndi maginito m'malo aulere.Mphamvu ya wailesi imayenda ngati "mafunde" omwe "amanjenjemera" kudutsa malo osasunthika.
Mphamvu ya wailesi ikafalikira ngati mafunde amagetsi, imakumana ndi zopinga, ndipo imatulutsanso zochitika zofananira ndi kuwunikira kapena kutsutsa ngati kuwala, mafunde amadzi, ndi mafunde amlengalenga monga Chithunzi(4).
Pambuyo powonekera pawayilesi kamodzi, gawo la mafundewa lidzasintha kwathunthu.Nsonga zimakhala ngati mbiya, ndipo mbiya zimasanduka mikwingwirima.Zoonadi, palinso zina mwangozi kuti njira yowonetseredwa ndi theka la kutalika kwa mafunde kuposa njira yolunjika.Kenako padzakhala nsonga zoikidwa pamwamba pa nsonga, ndi mbiya zoyikidwa pamwamba pa mbiya, ndipo chizindikirocho chidzalimbikitsidwa kwambiri.
LOS (Line Of Sight) kulumikizana opanda zingwe kuli ndi njira ziwiri zofalitsira: zolunjika ndi zowunikira.Ngati pali chopinga panjira yakufalitsa, kuti njira yolunjika itsekedwe, chizindikirocho chimangofikiridwa ndi chiwonetsero, chomwe chimatchedwa.wopanda mzere wamasokufalitsa (NLOS).Zotsatira za kufalitsa zimachepetsedwa kwambiri.Palinso vuto lina, kutalika kwa chopingacho sichokwera kwambiri, njira yolunjika ikhoza kufika.Koma mtundu woterewu wowonetsera chizindikiro cha "chotukuka" watsekedwa, ndipo kukhudzidwa kwa kufalitsa kulinso kwakukulu.
Pakadali pano, mainjiniya amagwiritsa ntchito chigawo cha Fresnel kuti awunikire zovuta zomwe zimalepheretsa kulumikizana kwa mzere wamaso.Fresnel zone imaganizira zachindunji komanso zowunikira.Malingana ngati palibe zopinga ndipo palibe zopinga m'derali, mtunda wa kulankhulana ukhoza kuyerekezedwa.
Ckuphatikiza
Zopanda zingwemobilevlingalirotransmitteramagwira ntchito pamalopokumene onse awiri angathe kuonana si kulankhulana kwa mzere wa maso.Pokhapokha pamene malo a Fresnel zone akhutitsidwa ndi momwe kufalikira kwa mzere wowonera kungatheke.Zoyenera kuchitawekuchita ngati pali zopinga?Ngati chopingacho sichingasunthidwe, tikhoza kukweza mlongoti molingana ndi mfundo ya Fresnel zone.
