FPV vhidhiyo inogamuchira

FPV Vhidhiyo Receiver

Muvhidhiyo iyi, Ini ndicharatidza kubatana pakati peFPV VTX transmitter uye inogamuchira.
Iyo transmitter parameter yekumisikidza chishandiso inoda imwe yekuwedzera 12V simba rekuisa. Iyo transmitter inodawo 12V simba rekuisa.
Iyo programmer skrini inoratidza yazvino transmitter parameter. Kuburikidza neiyo transmitter's programmer, unogona kugadzirisa frequency ye transmitter, bandwidth, pasiwedhi, nezvimwewo. Kana ukashandisa kekutanga, haufanire kushandura chero parameter. Iyo yekumisikidza yatove yakanyanya kunaka uye yakaedzwa mufekitori.

Heino mugamuchiri, iyo yatova nediki skrini nemabhatani. Maparamita ari pano akafanana neanotumira. Kune zvakare SNR uye PW kukosha, SNR chiratidzo chemhando uye PW isimba rechiratidzo.
SNR uye PW kukosha kwakakosha. Iwe unofanirwa kutarisa aya ma parameter kazhinji.

Iyo programmer uye vhidhiyo yekupinda pane transmitter inogovera yakafanana yekuisa interface. Saka isu tinotanga tabvisa magetsi emugadziri. Bvisa mugadziri uye batanidza tambo yekupinza vhidhiyo. Pakushanda, ndapota rangarira kubvisa tambo yemagetsi ye transmitter uye usaishandise ichibatidzwa.

Iye zvino isu tinopa iyo transmitter chiratidzo chekuisa vhidhiyo. Zvadaro batanidza simba kune transmitter. Isu tinoisa iyo transmitter pane simbi simbi kuti ikurumidze kupisa kupisa kweiyo transmitter. Pa drone, unogona kushandisa propeller kubvisa kupisa kwakananga kune transmitter.

Mirira masekondi mashoma, uye chiratidzo chevhidhiyo kuti chioneke pane FPV vhidhiyo inogamuchira inoratidzwa. Iyo transmitter inotsigira SD 720P vhidhiyo yekuisa, uye inogamuchira inotsigira HDMI 1080P vhidhiyo kubuda. Iyo transmitter haishandise HDMI yekuisa nekuti SD ine yakaderera latency uye nekukurumidza encoding kumhanya. Semufambisi weFPV, low latency inonyanya kukosha kupfuura 1080P mufananidzo wemhando.

Takatsiva chiratidzo chevhidhiyo nekamera. Mufananidzo wevhidhiyo wakanyatsogadzikana uye wakachena, pasina mazaya echando kana mifananidzo.

SNR

Iko kukosha kweSNR inomiririra kunaka kweiyo isina waya siginecha kubva kune inotumira kune inogamuchira.

Iyo yakakura kukosha kweSNR ndeye, zviri nani chiratidzo chazvino chiri. Iyo yakaderera kukosha ndeye, iyo yakaipisisa chiratidzo chemazuva ano. Kana iyo SNR yakaderera pane 5 kuti 6, iyo chiratidzo kubva kune inotapurirana ichienda kune inogamuchira ichakanganiswa uye mufananidzo weanogamuchira unomira. Kana kuti mosaic inooneka.

Panguva iyi, kureba kweantenna yeanogamuchira kunofanirwa kugadziridzwa kana chinzvimbo cheanogamuchira chinofanirwa kufambiswa kukunda zvimwe zvipingamupinyi kuitira kuti kugamuchirwa kwechiratidzo kuve nani uye kukosha kweSNR kudzokere kumusoro kwe6 ~ 7..

Iko kukosha kweSNR kunongoratidzwa chete mushure mekunge transmitter yabatidzwa. nyanya, kukosha kweSNR kwakapoteredza 15dB, uye chiratidzo chevhidhiyo chakanyatsogadzikana. Kana kukosha kweSNR kuri pasi pe6dB, chiratidzo chevhidhiyo chinotonhora kana kupera.

PW

Nezve kukosha kwePW yeanogamuchira, iyi parameter inogona kutarisa kana iyo inogamuchira ine kukanganisa pane yazvino frequency. Hapana chikonzero chekubatidza transmitter. Iwe unongoda kubatanidza antenna inogamuchira uye nekuibatisa kuti uone kukosha kwePW. Kana iyo PW kukosha iri -80, nharaunda yazvino inokanganisa antenna inogamuchira. Kana iyo PW kukosha iri -90, nharaunda yemazuva ano yakanyatsojeka uye hapana kupindira kune antenna inogamuchira.

Kana kukosha kwePW kuri kushoma pane -80, zvinogona kunge zviri nekuti iyo inotumira iri pedyo zvakanyanya. Panguva iyi, iwe unofanirwa kugadzirisa chinhambwe pakati peanotumira uye anogamuchira zvakakodzera.
