Modula TX Veguheztina Vîdyoyê

1. Em dikarin bandfirehiya RF ya vê modelê li 2M / QPSK rast bikin û hestiyariya wergirtinê zêde bikin. -98 (rast), ku 7dB ji hestiyariya orjînal bilindtir e. Ev ê dûrahiya veguheztinê ya têkildar ji du qat zêdetir bike.
2. Tiştê ku UAV bala xwe dide mezinahî û giraniya Modula TX Veguheztina Vîdyoyê ye. Giraniya tevahiya makîneyê dikare di nav 100g de be.
3. Veguheztina Modula TX Veguheztina Vîdyoyê ya Wireless bi xwe derengiyek heye 75çirkan de
4. One-way COFDM video transmission, mainly used for FPV(First Person View)
5. SD video transmission, RF bandwidth up to 2M, end-to-end delay of less than 120çirkan de
6. Default 3W PA support 50km (THE)
7. The default working frequency is 595 Mhz, and we can customize 170~860 Mhz
8. Video encoding format: H265
9. Ebat: Motherboard size: 50 X 35 X 10mm; overall machine size: 67 X 48 X 23mm (3W and above lower output)

Modula RX Wergirê Vîdyoyê

RF Wireless Video Receiver Dimension 70×80×15mm

Here is the FPV video transmitter with a metal case.

Çima ev model ji çêtir e COFDM-912T wekî veguhestina vîdyoyê ya FPV?

Cûdahiya di navbera ragihandina vîdyoya bêserûber COFDM-912T û FPV1887 de ye

1. Derengiya derengiya vîdyoya veguhestina vîdyoyê ya FPV1887 piçûk e, bes 120 mîlîçirkeyan. Derengiya COFDM-912T ji 400ms zêdetir e.
2. Bi bandwidthên modulasyonê yên cihêreng, bi çareseriya rastîn a vîdyoyê, veguhestina vîdyoyê ya FPV1887 tenê hewce dike 2bandwidth MHz, dema ku COFDM-912T ji 6MHz zêdetir hewce dike.
3. FPV1887 heye dûr veguheztina dirêjtir, performansa difractionê ya bihêztir, û performansa dijî-destwerdana. Ji ber ku ew bandwidthek tengtir bikar tîne, hesasiyeta wergirtina wê ya bilindtir e û kêm çavkaniyan digire.
4. Mezinahî û giraniya piçûktir: Compared with COFDM-912T video transmission, the FPV-1887 video transmission adopts a more advanced encoding and modulation scheme, with lower overall power consumption, smaller size, and a weight of only 80g.
5. The unique 45-degree RF antenna design is more suitable for the FPV and is more suitable for the high-speed flight angle of the FPV.
6. The video transmission of this FVP1887 is suitable for vehicles with a flying speed of about 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 dipîve, 2 dipîve, 3 dipîve, û 4 dipîve. (default 3-watts support 50km)

Pirs û Bersîv

Pirs: Çima elektrîka li ser veguhêz dibe sedem ku qalikê wê pir germ bibe?

Bersiv: Yekem, we tested this circuit board at temperatures of minus 40 degrees and 85 dereceyên. The hand feels very hot and will not affect the normal use of the transmitter.
Duyem: 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 kîlometre, 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.

Pirs: Kevirê vê transmitterê pir giran xuya dike, û ji bo sazkirina li ser drona ku pêdivî ye ku sivik be ne guncaw e, rast?

Pirs: Hêza veguhestinê bêyî amplifikatorek zêde çi ye? 100-200mW?

Pirs: Çima bihayê veguhestina vîdyoya weya FPV ji veguhestina vîdyoya analog UHF bilindtir e?

Bersiv:

1. This FPV video transmitter is not an ordinary FM-modulated analog video transmission.
2. Ours is COFDM digital video transmission, not the FM-modulated analog video transmission you understand. Video Quality is SD720P, clearer, stewr. It is more resistant to interference and supports video encryption.
3. The FM-modulated video transmission frequencies are 1.2G, 1.3G, 2.4G, û 5.8 G. The biggest advantage of video transmission is that it is cheap. The transmission distance is limited to short distances with an eye-see line of sight.
4. Our FPV video transmitter can transmit HD video at ultra-low altitudes and non-line-of-sight conditions. A specialized receiver is required to decode it.

Pirs: Ma em dikarin dubarekerê bi xwe bi karanîna du komên wergir û veguhezker bicivînin?

Bersiv: Emîn, you can do like that.

If you need a relay and also control the plane, we recommend that you choose TX900, which just uses three units that can be formed a complete networking, stefartî, dubareker, and receiver.

If you just need a one-way transmission system to download the video from the UAV to the repeater or ground. We recommend using our FPV repeater devices. Ji kerema xwe wêneya jêrîn kontrol bikin. We have put the receiver and transmitter in one box.

There are two frequencies, bo nimûne, 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. Du fîlter û dubareker ne di yek qutikê de ne, heke hûn fermanê piştrast bikin, em ê li gorî uav xwe qazeke din bikin an jî bi xwe bikin kasib.

Relay an dubarekera bi navê, ku Kitek e ji bo ji nû ve veguheztina vîdyoyê ji bo dirêjkirina rêzê.

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

If the relay has two filters, is it still necessary to add a filter for the transmitter and receiver?
It is better to add a narrowband bandpass filter so that the reception performance will be very good.

Pirs: Fikra bikaranîna du antên heman li ser wergirê çi ye?

Bersiv: Li ser wergirê du antenên cihêreng hene. Yek baş e, du çêtir e, da ku bêtir sînyalê ji transmitterê bistînin, û performansa resepsiyonê zêde bikin.

Pirs: Berfirehiya kanalê çi ye?

Bersiv: Vebijêrk 6 Mb e. Her weha hûn dikarin wê ji 2 MB biguherînin, 4MB, 6MB, an jî 8MB heke hûn bixwazin û ji bo veguhezker panela amûra pîvana zêde bikirin. Çêtir e ku hûn li mîhenga meya xwerû test bikin.

Pirs: Ma ez dikarim antenna rêwerzek bi dorvegerekê re bikim yek?

Pirs: Is it possible to set the input and output video type manually (PAL / NTSC)?

Bersiv: PAL / NTSC hem piştgirî dike, oto-naskirin, û li gorî kamera têketina xwe biguherînin.

Pirs: We need a configured board for the transmitter. How much it costs?

Bersiv: Ji bo kêmkirina giraniya giştî ya transmitterê, amûra mîhengê ya veguhezkerê derveyî ye. Heke hûn nebin, pergal di mîhenga meya xwerû de jî baş dixebite. Ger we hebe, hûn dikarin pîvanên veguhestinê biguherînin, wek frekansa, bandwidth, Şîfreya AES, hwd..

Pirs: Does the receiver have analog and HDMI output?

Bersiv: Erê, wergirê hem analog heye (CVBS, derketina vîdyoyê ya pêkhatî) û derketina vîdyoya HDMI.
Ji bo ku derengiya vîdyoyê kêm bikin, mîhenga xwerû, HDMI tenê nîşanek vîdyoyê ye, sînyala deng tune.

Pirs: Extra wave filters for drones – we need this (how much does it cost?)

Bersiv: Veguheztina FPV di hundurê de jixwe ji bo drone parzûnek kêm derbasbûnê heye. Ji kerema xwe ji me re bêje ka çi hewcedariyên we hewce ne.
Parzûnên Frequency du celeb hene, yek jê parzûna kêm-derbasbûnê ye, such as the working frequency is 595Mhz, then over 610Mhz can not be passed. Another filter type is bandwidth pass filter, such 580~610Mhz can be passed, others can not be passed.

FAQs

1. Does your FPV video transmitter work well in the jammer at the below frequency?

Bersiv:

The default frequency is 595Mhz, (the center working frequency of the power amplifier and antenna is 595Mhz, ) I checked that this is not the range of your table mentioned. Di pêşerojê de, the anti-drone jammer may cover 595Mhz, we also can preset different frequencies chosen from 170-860Mhz.

2. How can I transmit telemetry of the flight controller with overlay on the video channel?

MinimOSD is the function to transmit telemetry of the flight controller with overlay on the video channel.

3. Does your FPV camera transmitter support transmitting 1-way data as telemetry to the ground?

Alîkarî.
