Hobaneng Boleng ba Phetiso ea Video bo Khetholla Katleho ea Mosebetsi oa Drone
Tsamaisong efe kapa efe ea drone—ebang ke ea FPV, ea ho shebella, kapa ea ho hlahloba AI—mojule oa phetiso ea video ke fensetere ea mokhanni ea shebileng leholimong.
Empa ho feta 40% ea ho hloleha ha li-drone tse tsamaeang tšimong mesebetsing ea tlhokomelo le tlhahlobo ho bakoa ke ho tlohela matšoao, ho thothomela ha video, kapa tšitiso ea RF (mohloli: Tlaleho ea Mekhoa ea Li-UAV tsa Khoebo ea 2024).
Esita le tieho ea 100ms ka 60 fps e ka fella ka lipheo tse lahlehileng kapa tokiso e feteletseng ea mofofisi peisong ea FPV e lebelo le phahameng.
Drone ea boemo ba profeshenale e tlameha ho ba le sistimi ea video TX e leng:
- Latency e tlase (ka ho khetheha
- Ha e sitisehe (haholo-holo mabapi le dienjene, di-ESC, GPS)
- E na le bokhoni ba HD (720p–1080p e nang le ho kenya khoutu e feto-fetohang)
- E lumellana le liteishene tsa fatše kapa likhalase tsa mahlo (HDZero, DJI O3, analoge)
Moralo oa Sistimi ea Mojule oa Phetiso ea Video ea Drone
| Karolo | Mosebetsi | Tlhokomeliso ea Moralo |
|---|---|---|
| Sebopeho sa Khamera | E amohela ho kenya video ka dijithale (MIPI, HDMI) | Sebopeho se tsamaellanang le impedance e potlakileng |
| Sekhoutu | E hatella lets'oao ka ho sebelisa H.264/H.265 | Ho bohlokoa ho laola ho thothomela ha mocheso le ho laola ho thothomela ha oache |
| RF Front End (TX) | E fetisetsa lets'oao ho feta 5.8GHz / 2.4GHz | Ho sireletsa, ho hatella harmonic |
| Tsamaiso ea Matla | Literene tsa 3.3V, 5V, 12V | Sebelisa ho sefa ha LC + diode tsa TVS |
| Kou ea Antena | E hokela ho li-antenna tse otlolohileng/tse chitja tse nang le polarized | 50Ω mohlala o tšoanang, tsela e thehiloeng moeling |
⚠️ U se ke ua hlokomoloha lerata la ho fetola le tsoang ho li-converter tsa DC-DC tse ka hare ho sekepe haufi le encoder. Ke mohloli o atisang ho ba le lintho tse hlahisang li-ghosting.
Melao ea Bohlokoa ea Moralo bakeng sa Phetiso ea Video ea UAV e Tsitsitseng le e Hlakileng
1. Tsela ea Phapang ea Lebelo le Phahameng (MIPI/HDMI)
- Impedance e fapaneng ea 100Ω e laoloang
- Qoba bolelele ba stub >3mm
- Bolelele bo tsamaellanang ka hare ho ±10mil
2. Leano la Tšireletso ea EMI le RF Fats'e
- Sebelisa mobu o tiileng tlas'a likarolo tsa RF
- Kenya li-via tsa ho roka ka 2cm e 'ngoe le e 'ngoe tseleng ea video
- Lithebe tsa tšepe holim'a libaka tsa RF + encoder
- Boloka sebaka se ka bang >10mm ho tloha ho ESC le dienjene
3. Tsamaiso ea Thermal
- Koporo e tšeloa tlas'a encoder IC
- Kenya li-vias tsa mocheso tsa 0.3mm (pad ea 0.6mm) ho GND
- Bakeng sa di-encoder tsa 4K, eketsa libaka tsa heatsink tse qobelloang
4. Ho sefa motlakase
- Li-filter tsa PI (10µF + 0.1µF + ferrite) holim'a seporo se seng le se seng sa motlakase
- Sebelisa diode tsa TVS (mohlala, PESD5V0S1UL) bakeng sa tšireletso ea ESD koung ea antenna
Likopo ka Indasteri le Litlhaloso tse Khothalelitsoeng
| Kopo | Litlhoko tsa Bohlokoa | Khothaletso |

| Tlhahlobo ea Liindasteri | Ho hlaka ha 1080p, ho hanela EMI | Sekhoutu sa H.264 + 5.8GHz RF se nang le sekoahelo se tšoanang |
| Lifofane tse se nang mahahapa tsa temo | Sebaka se selelele, se tsitsitseng tlas'a thothomelo | Mojule oa 2.4GHz + lihokelo tse kentsoeng ka likurufu |
| Tšireletso le Tlhokomelo | Phallo ea nako ea sebele ka GPS overlay | Tlhahiso ea RTMP/UDP + module ea RF e patiloeng |
| Li-drone tsa AI (CV / ML) | Fepa e nang le tahlehelo e tlase bakeng sa ho lemoha ntho | Video ea RAW MIPI + sesebelisoa sa pele sa buffer |
Liphoso tse Tloaelehileng tse Senyang Boleng ba Video ea UAV
| Phoso | Tšusumetso | Tharollo |
|---|---|---|
| Sefofane se arolelanoang fatše le ESCs | Lerata la EMI, ho tlohela sekolo | Sebelisa lifofane tse arohaneng, ho theola naleli ea ntlha e le 'ngoe |
| Ha ho phomolo ea mocheso bakeng sa encoder | Ho futhumatsa ho feta tekano → skrine e ntšo | Kenya li-vias tsa mocheso + li-heatsink |
| Mela ea video e lebelo le phahameng e kobeha ka 90° | Lipontšo tsa matšoao | Sebelisa litsela tse kobehileng tsa 45° kapa litsela tse potileng |
| Molaetsa o molelele oa antenna ntle le ho bapisa | Letšoao la tahlehelo | Netefatsa hore 50Ω impedance + e kopantsoeng ka lehlakore le thehilweng |
| Taolo ea ho chencha e haufi haholo le RF | Setshwantsho se phoqang | Thebe + sebaka se ka bang >20mm ho tloha tseleng ea encoder |
Hobaneng o Sebetsa le Rich Full Joy ho Video TX Module Design & Assembly
- ✅ Lilemo tse fetang 20 Moralong oa PCB o Phahameng ka ho Fetisisa
- ✅ Phihlelo ho RF TX Modules ho fihlela ho 6GHz
- Tšehetso e Felletseng ea DFM/DFT bakeng sa Liboto tsa Video tsa UAV
- ✅ Ho sireletsa, ho kenya lipitsa, le ho roala ka mokhoa o sa fetoheng hoa khoneha
- ✅ Potoloho e Potlakileng ea Prototype + Bongata ba PCBA bakeng sa Li-OEM tsa Drone
📌 Hore na o hloka boto e nyane ya analog TX bakeng sa di-drone tsa mabelo kapa sesebelisoa sa dijithale sa 1080p encoder + RF stack bakeng sa tlhokomelo e ikemetseng, re e rala, re e etsa, mme re e kopanya - tsohle di sebetsa ka hare ho ntlo.
