Nansi i-FPV video transmitter enekesi lensimbi.

Kungani le modeli ingcono kune COFDM-912T njenge-FPV video transmitter?

Umehluko phakathi kwe-COFDM-912T kanye ne-FPV1887 yokudluliswa kwevidiyo engenantambo

1. Ukubambezeleka kwevidiyo yokudlulisa ividiyo ye-FPV1887 kuncane, kuphela 120 millisecond. Ukubambezeleka kwe-COFDM-912T kungaphezu kuka-400ms.
2. Ngama-bandwidths ahlukene wokumodulation, nesinqumo esiqondile sevidiyo, ukudluliswa kwevidiyo ye-FPV1887 kudinga kuphela 2MHz komkhawulokudonsa, kuyilapho i-COFDM-912T idinga okungaphezu kuka-6MHz.
3. I-FPV1887 ine-a ibanga elide lokudlulisa, ukusebenza kwe-diffraction enamandla, nokusebenza okungahambisani nokuphazamiseka. Ngoba isebenzisa umkhawulokudonsa omncane, inokuzwela okuphezulu kokwamukela futhi ithatha izinsiza ezimbalwa.
4. Usayizi omncane nesisindo: Uma kuqhathaniswa nokudluliswa kwevidiyo ye-COFDM-912T, ukudluliswa kwevidiyo ye-FPV-1887 kusebenzisa uhlelo lokubhala ngekhodi oluthuthuke kakhulu kanye nokushintshashintsha, ngokusetshenziswa kwamandla jikelele okuphansi, usayizi omncane, kanye a isisindo - 80 g kuphela.
5. Idizayini eyingqayizivele ye-45-degree RF antenna ifaneleka kakhulu i-FPV futhi ifaneleka kakhulu i-angle yendiza ye-FPV enesivinini esikhulu..
6. Ukudluliswa kwevidiyo kwale FVP1887 kulungele izimoto ezinesivinini esindizayo esingaba ngu-120km. For vehicles with higher flying speeds, the video delay will appear larger and the control will not be so good.
7. More amplifiers to choose from 1 Watts, 2 Watts, 3 Watts, futhi 4 Watts. (default 3-watts support 50km)

FAQ

umbuzo: Kungani amandla ku-transmitter kubangela ukuthi igobolondo layo lishise kakhulu?

impendulo: Okokuqala, we tested this circuit board at temperatures of minus 40 degrees and 85 degrees. The hand feels very hot and will not affect the normal use of the transmitter.
Okwesibili: There are two reasons why the case temperature is a bit high:

1. To be waterproof, our casing does not have heat dissipation holes and fan holes.
2. To support 50 amakhilomitha, we have a built-in three-watt amplifier. A power amplifier requires a cooling fan. The chip and board of the power amplifier are close to the metal casing to transfer heat.

umbuzo: Igobolondo lale transmitter libukeka lisinda kakhulu, futhi ayifanele ukufakwa kundiza engasindi, kwesokudla?

umbuzo: Ayini amandla we-transmitter ngaphandle kwe-amplifier eyengeziwe? 100-200MW?

umbuzo: Kungani intengo yesidluliseli sevidiyo ye-FPV yakho iphezulu kunesidlulisi sevidiyo ye-analog ye-UHF?

impendulo:

1. Lesi sidlulisi sevidiyo se-FPV asikona ukudluliswa kwevidiyo ye-analog ejwayelekile ye-FM.
2. Eyethu i-COFDM digital video transmission, hhayi ukudluliswa kwevidiyo ye-analog emodelwe i-FM oyiqondayo. Ikhwalithi yevidiyo ingu-SD720P, kucace kakhudlwana, ezinzile. Imelana kakhulu nokuphazamiseka futhi isekela ukubethelwa kwevidiyo.
3. Izandiso zokudluliswa kwevidiyo ezimodliwe yi-FM ziyi-1.2G, 1.3G, 2.4G, futhi 5.8 G. Inzuzo enkulu yokudluliswa kwevidiyo ukuthi ishibhile. Ibanga lokudlulisela lilinganiselwe kumabanga amafushane ngomugqa wokubona ngeso.
4. Isidlulisi sethu sevidiyo se-FPV singakwazi ukudlulisa ividiyo ye-HD ezindaweni eziphakeme kakhulu eziphansi nezimo ezingezona umugqa wokubona. Kudingeka umamukeli okhethekile ukuze uyiqophe.

umbuzo: Singakwazi yini ukuhlanganisa okuphindaphindayo ngokwethu sisebenzisa amasethi amabili abamukeli nama-transmitters?

impendulo: Impela, ungenza kanjalo.

Uma udinga edluliselwe futhi ulawule indiza, sincoma ukuthi ukhethe TX900, esebenzisa amayunithi amathathu nje angakha inethiwekhi ephelele, Lidlulisela, ophindayo, nomamukeli.

Uma nje udinga isistimu yokudlulisela indlela eyodwa ukuze udawunilode ividiyo isuka ku-UAV iye kusiphindaphinda noma phansi. Sincoma ukusebenzisa amadivayisi wethu wokuphinda we-FPV. Sicela uhlole isithombe esingezansi. Sibeke umamukeli nesidlulisi ebhokisini elilodwa.

There are two frequencies, Ngokwesibonelo, 800Mhz from the transmitter to the repeater, and 300Mhz from the repeater to the receiver
To avoid interference, you also add two filters, and PA in the repeater module to increase the signal strength.
The above picture is from our engineer, he has a real sample now. The two filters and repeater are not in one box, if you confirm the order, we will do another casing or do casing by yourself according to your uav.

Relay or named repeater, which is a Kit for video re-transmission to extend the range.

The repeater with two filters is almost 450 amagremu, not including the antenna.

If the relay has two filters, is it still necessary to add a filter for the transmitter and receiver?
Kungcono ukwengeza isihlungi se-narrowband bandpass ukuze ukusebenza kokwamukela kuzoba kuhle kakhulu.

umbuzo: Uyini umqondo wokusebenzisa izinti ezimbili ezifanayo kumamukeli?

impendulo: Kunezimpondo ezimbili ezihlukene kumamukeli. Omunye ulungile, okubili kungcono, ukuze uthole isignali eyengeziwe kumthumeli, futhi andise ukusebenza kokwamukela.

umbuzo: Uyini umkhawulokudonsa wesiteshi?

impendulo: Okuzenzakalelayo kungu-6Mb. Ungayishintsha futhi isuke ku-2MB, 4MB, 6MB, noma 8MB uma ufuna futhi uthenge ibhodi lamathuluzi epharamitha eyengeziwe yesithumeli. Kungcono ukuthi uhlole kusilungiselelo sethu esizenzakalelayo.

umbuzo: Ngingakwazi ukuhlanganisa i-antenna eqondisayo nesiyingi?

umbuzo: Kungenzeka yini ukusetha ngesandla uhlobo lwevidiyo yokufaka nokuphumayo (PAL / NTSC)?

impendulo: PAL / I-NTSC yomibili isekela, thola ngokuzenzakalelayo, bese ushintsha ngokuya ngekhamera yakho yokufaka.

umbuzo: Sidinga ibhodi elimisiwe le-transmitter. Ibiza malini?

impendulo: Ukuze wehlise isisindo somthumeli, ithuluzi lokumisa le-transmitter lingaphandle. Uma ungenayo, isistimu nayo isebenza kahle kusilungiselelo sethu esizenzakalelayo. Uma unayo, ungashintsha amapharamitha we-transmitter, njengokuvama, komkhawulokudonsa, Iphasiwedi ye-AES, njll.

umbuzo: Ingabe umamukeli unokuphumayo kwe-analog ne-HDMI?

impendulo: Yebo, umamukeli unazo zombili i-analog (CVBS, okukhipha ividiyo eyinhlanganisela) kanye nokukhishwa kwevidiyo ye-HDMI.
Ukuze wehlise ukubambezeleka kwevidiyo, ukulungiselelwa okuzenzakalelayo, I-HDMI iyisiginali yevidiyo kuphela, ayikho isignali yomsindo.

umbuzo: Izihlungi zegagasi ezengeziwe zama-drones – siyakudinga lokhu (kubiza malini?)

impendulo: I-transmitter ye-FPV ngaphakathi isivele inesihlungi sokudlula esiphansi ngaphakathi kwe-drone. Sicela usitshele ukuthi yiziphi izidingo ozidingayo.
Izihlungi zeFrequency zinezinhlobo ezimbili, esinye isihlungi se-low-pass, njengokuvama kokusebenza ngu-595Mhz, khona-ke ngaphezu kwe-610Mhz ayikwazi ukudlula. Olunye uhlobo lwesihlungi isihlungi sokudlula komkhawulokudonsa, okungaka 580 ~ 610Mhz kungadluliswa, ezinye azikwazi ukudlula.

umbuzo: Sidinga okokufaka okuqondile kwe-antenna ye-RF kukesi lensimbi le-FPV video transmitter. Ungakwazi yini ukukwenza?

umbuzo: Amandla esithumeli nomamukeli 12 ama-volts? Yini ama-ampere?

umbuzo: Yiziphi izilungiselelo ezizenzakalelayo zalesi sidlulisi nesamukeli sekhamera ye-FPV? (Usetha kanjani kabusha kuzilungiselelo zasefekthri)

Okufanele usitshele uma u-oda?

imvamisa

Ifrikhwensi ezenzakalelayo ingu 595 MHz. Sine stock TX kanye RX antenna for 595Mhz. Okwamanye amafrikhwensi, sidinga cishe izinsuku eziyishumi ukwenza ngendlela oyifisayo uthi kanye ne-PA amplifier yamandla.

Antenna

Hlobo luni lwe-antenna oludingayo? I-antenna edlulisa isiswebhu? 60cm ubude be-fiberglass antenna enobakaki wohlobo lwe-U? noma ngesisekelo kazibuthe sothi olungaphakathi emotweni?

Ithuluzi Lokumisa Ipharamitha Engeziwe le-TX

Ibhodi Lethuluzi Lokumisa Ipharamitha Engeziwe Lokudluliswa kwe-Transmitter yi-USD45 kubathengi abangochwepheshe. (Umamukeli unakho isikrini kanye nemenyu ukulungisa ipharamitha).
