Vim li cas qhov zoo ntawm kev xa video txiav txim siab qhov ua tiav ntawm Drone Mission
Hauv txhua lub drone system—txawm yog FPV, kev saib xyuas, lossis AI reconnaissance—lub video transmission module yog lub qhov rais ntawm tus neeg teb xov tooj mus rau saum ntuj.
Txawm li cas los xij, ntau tshaj 40% ntawm kev ua tsis tiav ntawm drone hauv thaj teb hauv kev saib xyuas thiab kev tshuaj xyuas cov haujlwm yog tshwm sim los ntawm kev poob teeb liab, video jitter, lossis RF cuam tshuam (qhov chaw: 2024 Commercial UAV Systems Report).
Txawm tias qhov qeeb 100ms ntawm 60 fps tuaj yeem ua rau lub hom phiaj tsis tau lossis tus tsav tsheb overcorrection hauv kev sib tw FPV ceev ceev.
Ib lub drone uas ua haujlwm tau zoo yuav tsum muaj lub kaw lus video TX uas yog:
- Qis-latency (qhov zoo tshaj plaws
- Tiv thaiv kev cuam tshuam (tshwj xeeb tshaj yog nyob ib puag ncig cov motors, ESCs, GPS)
- Muaj peev xwm siv tau HD (720p–1080p nrog kev hloov kho encoding)
- Tau tshaj nrog chaw nres tsheb hauv av lossis tsom iav (HDZero, DJI O3, analog)
Kev Tsim Qauv System ntawm Drone Video Transmission Module
| Cheebtsam | Kev Ua Haujlwm | Tsim Qauv Cim |
|---|---|---|
| Lub koob yees duab sib txuas | Txais cov tswv yim digital video (MIPI, HDMI) | Kev teeb tsa impedance sib phim nrog high-speed |
| Tus encoder | Siv H.264/H.265 los nias cov teeb liab | Kev pab txo qhov kub thiab tswj lub moos jitter tseem ceeb |
| RF Pem Hauv Ntej (TX) | Xa cov teeb liab tshaj 5.8GHz / 2.4GHz | Kev tiv thaiv, kev tswj hwm harmonic |
| Kev Tswj Fais Fab | 3.3V, 5V, 12V txoj kab | Siv LC filtering + TVS diodes |
| Chaw nres nkoj Antenna | Txuas rau cov kav hlau txais xov linear/circular polarized | 50Ω phim qhov ntsuas, kev sib txuas ntawm ntug kev |
⚠️ Tsis txhob saib tsis taus lub suab nrov hloov pauv los ntawm cov hloov pauv DC-DC nyob ze ntawm lub encoder. Nws yog qhov chaw uas muaj cov khoom cuav ghosting ntau zaus.
Cov Cai Tsim Qauv Tseem Ceeb rau Kev Xa Yeeb Yaj Kiab UAV Ruaj Khov, Pom Tseeb
1. Kev Sib Txuas Lus Sib Txawv Ceev (MIPI / HDMI)
- Tswj tau 100Ω qhov sib txawv impedance
- Tsis txhob siv lub stub ntev tshaj 3 hli
- Qhov ntev sib phim hauv ± 10mil
2. EMI Shielding thiab RF Av Txoj Kev Npaj
- Siv cov av khov kho hauv qab cov khoom RF
- Ntxiv cov xov txuas txhua 2cm raws txoj kev video
- Cov hlau thaiv hla RF + encoder zones
- Khaws qhov nrug > 10 hli ntawm ESCs & motors
3. Kev Tswj Xyuas Kub
- Tooj liab ncuav rau hauv qab encoder IC
- Ntxiv 0.3 hli thermal vias (0.6 hli pad) rau GND
- Rau 4K encoders, ntxiv cov cheeb tsam cua sov uas raug yuam kom ua haujlwm
4. Kev lim fais fab
- Cov lim dej PI (10µF + 0.1µF + ferrite) ntawm txhua txoj kab hluav taws xob
- Siv TVS diodes (piv txwv li, PESD5V0S1UL) rau kev tiv thaiv ESD ntawm qhov chaw nres nkoj antenna
