Mafupipafupi a wailesiUkadaulo wa (RF) ndi ukadaulo wolumikizirana wopanda zingwe, womwe umagwiritsidwa ntchito kwambiri pa wailesi, kulumikizana, radar, remote control, ma network a sensa opanda zingwe ndi madera ena. Mfundo ya ukadaulo wa wailesi wopanda zingwe imachokera pa ukadaulo wofalitsa ndi kusintha ndi kugawa mafunde amagetsi. Pansipa ndikukufotokozerani mfundo ya ukadaulo wa wailesi wopanda zingwe.
Mfundo zaukadaulo
Ukadaulo wa ma wailesi opanda zingwe ndi ukadaulo womwe umagwiritsa ntchito mafunde a wailesi polumikizirana. Mafunde a wailesi kwenikweni ndi mtundu wa mafunde amagetsi okhala ndi ma frequency ndi mipata yapadera. Mu kulumikizana kwa ma wailesi opanda zingwe, gawo lotumizira mauthenga limasintha zizindikiro za chidziwitso kukhala zizindikiro za mafunde amagetsi kudzera mu mafunde a wailesi ndikuzitumiza. Gawo lolandira limalandira zizindikiro za mafunde amagetsi kenako nkuzisintha kukhala zizindikiro za chidziwitso kuti zikwaniritse kutumiza deta ndi kulumikizana.
Mfundo yoyendetsera ma radio frequency ndi kutumiza
Mfundo za ukadaulo wa wailesi yopanda zingwe zimaphatikizapo zinthu izi:
Kusintha kwa mafupipafupi: Mu mauthenga a wailesi opanda zingwe, zizindikiro za chidziwitso zimasinthidwa kukhala zizindikiro zamafunde amagetsi a ma frequency apadera kutengera ukadaulo wa modulation. Njira zodziwika bwino zosakaniza zimaphatikizapo amplitude modulation blending (AM), frequency modulation blending (FM), ndi phase modulation blending (PM).
Antena: Antenandi gawo lofunika kwambiri pa kulumikizana kwa ma wailesi opanda zingwe. Limagwiritsidwa ntchito kutumiza ndi kulandira zizindikiro za mafunde a wailesi. Kapangidwe ndi malo a ma antenna zimakhudza mtunda wotumizira mauthenga ndi ubwino wa mauthenga opanda zingwe.
Antena ya nyanga ya Broadband (1-18GHz)
Antena ya Horn Yodziwika Bwino (4.90-7.05GHz)
Antena ya Horn Yokhala ndi Magawo Awiri Yozungulira (2-18GHz)
RF Misomalingaliro a zinthu za antenna
Kulemba ndi kutanthauzira njira: Mu kulumikizana kwa ma wailesi opanda zingwe, ukadaulo wokonza ma code ndi ma decoding a channel umagwiritsidwa ntchito kuti ukhale wolimba komanso woletsa kusokonezana kwa mauthenga ndikuwonetsetsa kuti kulumikizana kwa deta kuli kolondola.
Kusamalira mphamvu: Kulankhulana kwa wailesi opanda zingwe kuyenera kusintha mphamvu yokankhira kuti zitsimikizire kuti chizindikirocho chikhoza kutumizidwa mkati mwa mtunda winawake ndikuchiletsa kuti chisakhudze china.
Kusamalira gulu la ma frequency: Kulankhulana kwa ma wailesi opanda zingwe kuyenera kuyang'anira bwino zinthu za sipekitiramu kuti tipewe kukhudzidwa ndi zinthu za ma frequency band zomwe zawonongeka ndikuwonetsetsa kuti kulumikizana kuli kokhazikika komanso kodalirika.
Zochitika zogwiritsira ntchito
Ukadaulo wa wailesi yopanda zingwe umagwiritsidwa ntchito kwambiri m'madera amakono, zomwe zimapangitsa kuti anthu azikhala ndi zinthu zambiri zatsopano komanso zatsopano pa moyo wawo komanso ntchito zawo. Nazi zina mwa njira zodziwika bwino zogwiritsira ntchito wailesi yopanda zingwe:
Kulankhulana pafoni: Maziko a kulumikizana kwa mafoni kwenikweni ndi ukadaulo wa ma wailesi, kuphatikizapo mafoni am'manja, ma network opanda zingwe, kulumikizana kwa satellite, ndi zina zotero. Zipangizo zamakonozi zimalola anthu kuyimba mafoni, kutumiza mauthenga, komanso kugwiritsa ntchito intaneti nthawi iliyonse komanso kulikonse.
Nyumba yanzeru: Mu makina anzeru a nyumba, monga maloko anzeru a zitseko, zowongolera magetsi anzeru, zida zanzeru zapakhomo, ndi zina zotero, zowongolera kutali ndi kasamalidwe kanzeru zimatha kuchitika kudzera muukadaulo wopanda zingwe.
Intaneti ya Zinthu: Ukadaulo wa wailesi wopanda zingwe ndi gawo lofunika kwambiri pa intaneti ya zinthu. Umathandiza kuti zipangizo zizilumikizana kudzera mu ma network a masensa opanda zingwe ndipo umathandiza kuti zipangizo ziziyang'aniridwa mwanzeru, kusonkhanitsa deta komanso kuwongolera kutali.
Netiweki ya sensor yopanda zingwe: Mu ma network opanda zingwe a masensa, imagwiritsidwa ntchito makamaka pakuwunika chilengedwe, thanzi lachipatala, kuwongolera mafakitale ndi madera ena kuti akwaniritse kusonkhanitsa deta ndikuwunika nthawi yeniyeni.
Zipangizo zowongolera kutali zopanda zingwe: Ukadaulo wa wailesi wopanda zingwe umagwiritsidwa ntchito kwambiri m'magawo owongolera monga zowongolera kutali za TV, zowongolera magalimoto, ndi zowongolera zamitundu kuti amalize ntchito zakutali.
Dongosolo la radar: WailesiUkadaulo wa ma frequency umagwira ntchito yofunika kwambiri mu radar systems ndipo umagwiritsidwa ntchito pozindikira zolinga, kutsatira ndi kuyenda. Umagwiritsidwa ntchito kwambiri mu aerospace, meteorology ndi madera ena.
Kugwiritsa ntchito ukadaulo wa wailesi yopanda zingwe ndi kwakukulu kwambiri, kumakhudza magawo ambiri, monga kulumikizana ndi mafoni, kulumikizana ndi satellite, makina a radar, zowongolera kutali, ma network a masensa opanda zingwe, ndi zina zotero. Ndi chitukuko chopitilira cha ukadaulo, ukadaulo wa wailesi yopanda zingwe upitilizabe kugwira ntchito yofunika kwambiri m'magawo osiyanasiyana, kubweretsa zosavuta komanso zatsopano m'miyoyo ya anthu ndi ntchito zawo.
