Thaum txuas cov koob yees duab kev lag luam rau lub drone, koj yuav tsum xaiv qhov tsim nyog tsim nyog thiab cable raws li hom koob yees duab, nws cov haujlwm, thiab cov khoom tsim kho ntawm cov drone. Hauv qab no yog cov kev sib txuas lus sib txuas thiab cov kev txiav txim siab tseem ceeb:
1. Cov hom inface
1. USB 3.0 / 3.1 (hom-c)
- Lub Hom Phiaj: Kev sib kis ntawm cov ntaub ntawv duab (txog li 5-10gbps).
- Cable yuav tsum tau: Luv luv (<3 m), shielded twisted pair cable, lightweight design.
- Daim Ntawv Thov Kev Ua Si: Cov kev daws teeb meem siab pom pom lub koob yees duab lub teeb (xws li Sony RX0), ntau ntau-spectral koob yees duab.
Lus Cim: Ntev nrug deb kev ua kom pom tseeb, yuav tsum tau ntxiv rov ua dua tshiab lossis siv cov cable ua haujlwm.
2. Gige (gigabet Ethernet)
- Siv: cov ntaub ntawv ntev-sib kis (tsis pub dhau 100 meters, 1Gbps).
- Cable yuav tsum tau: Cat6 / Cat6a Shielded network cable, PEe (Hwjchim dhau Ethernet) tuaj yeem txo cov hluav taws xob ntxiv.
- Daim Ntawv Thov Kev Ua Si: Lidar (piv txwv li Velodyne), ntau sensor fusion system.
Nco tseg: UT yuav tsum tau txais kev pab txhawb poe hloov chaw lossis hluav taws xob muab cov khoom siv.
3. HDMI / SDI
- Lub Hom Phiaj: Lub sijhawm yees duab tiag tiag (1080p / 4k).
- Cable yuav tsum tau: Tsawg Latency Coaxial Kab (HDMI) lossis BNC interface Cable (SDI).
- Daim Ntawv Thov Kev Ua Si: Lub koob yees duab Aerial (xws li Dji Zenmuse), kev tshuaj xyuas cov kev tshaj tawm.
NCO TSEG: HDMI yog cov khoom tsis zoo rau hluav taws xob cuam tshuam nrog hluav taws xob daws teeb meem thiab xav tau kev tiv thaiv.
4. MIPI CSI-2
- Lub Hom Phiaj: Embedded lub koob yees duab ncaj qha txuas nrog davhlau tswj (xws li raspberry PI lossis NVIDIA Jetson).
- Cable yuav tsum tau: Saj zawg zog ncaj Cable (FPC / FPC), qhov ntev yog feem ntau<30cm.
- Daim Ntawv Thov Kev Ua Yeeb Yam: Lub teeb rau Ai Ntug suav cov koob yees duab (xws li cov khoom ua haujlwm zed cov koob yees duab).
Nco tseg: CSI interface yog tshwj tseg rau lub davhlau tswj hwm thiab tsuas yog siv rau cov nruab nrab.
5. Coaxpress (Cxp)
- Siv: ultra-kev kub ceev cov koob yees duab (6.25gbps / channel, Ntau tus neeg nruab nrab ntawm cov neeg vwm).
- Cable yuav tsum tau: coaxial kab (txhawb nqa ntev ntev, muaj zog tiv thaiv kab mob).
- Daim Ntawv Thov Kev Ua Yeeb Yam: Cov Koob Yees Duab Ceev Ceev Faj (xws li Photron Sa-Z Series).
Nco tseg: Cov npav tshwj xeeb yog qhov yuav tsum tau ua, tus nqi yog siab.
2. Fais Fab Kev Xav Tau
- Independent zog av:
Cameras with high power consumption (such as thermal imagers) need to be powered separately, and 12V/24V DC power cables are commonly used.
Yuav tsum muaj roj teeb drone lossis roj teeb uas ntxiv.
- PoE (Hwjchim hla Ethernet):
Gige interface cov koob yees duab tuaj yeem siv los ntawm lub network cable (xws li FLIR dub dub s).
- Tsawg zog hluav taws xob USB fais fab mov:
USB 3.0 muab 5V / 1A muab hluav taws xob rau cov koob yees duab me.
3. Synchronization thiab Ntsuas Intergace Interface
- GPO (General Cov Lus Qhia / Tso Tawm):
Rau kev tsav davhlau thiab lub koob yees duab kho vajtse synchronization (xws li shutter trigger).
Lub PWM / GPIO pins ntawm lub davhlau tswj yuav tsum tau txuas nrog dupont lossis kev cai sawb cov xov hlau.
- PPS (pulses ib ob):
Lub sijhawm ua haujlwm synestamp (qhov tseeb ± 1μs) yog muab ntawm GPS module.
- Hardware ua tus ua kom loj dua cable:
Thaum ntau cov koob yees duab ua haujlwm ua ke, tus tswv / qhev BRigger cim teeb liab kab yog qhov yuav tsum tau (xws li ntau lub koob yees duab ntau hom spray).
4. Nruab Nruab Nruab Nrab Cheeb Tsam
- Shopp-ntawv pov thawj txuas:
Siv lub ntsuas cua sov nrog lub xauv caij nplooj ntoos hlav (xws li Lemo lossis M12 txuas) kom tiv thaiv kev co los ntawm ua rau nws poob tawm.
- Electromagnetic Tiv Thaiv Shielding:
Lub cable yog qhwv nrog ib txheej hlau ua ke los yog lub nplhaib sib nqus los txo lub zog cuam tshuam ntawm cov drone.
- Kev Tswj Cable:
Cables tau tsau nrog nylon cable sib txuas thiab ua kom sov kom deb ntawm cov leeg kom tsis txhob entangling lub kiv cua.
5. Cov qauv teeb tsa ib txwm ua piv txwv
- Daim Ntawv Thov Kev Ua Si Cov Vev Xaib Yees Duab Hom Interface Scheme Xaiv
- Precision Kev Ua Liaj Ua Ua Ua Liaj Ua Ua Ua Liaj Ua Ua Liaj Ua Ua Liaj Ua Zog Ntau-Spectral Lub Koob Yees Duab Gige + Poe Fais Fab Cat6a Shielded Network Cable
- FAIS FAIS Soj ntsuam Lub Koob Yees Duab USB3.1 +}}} agon} AGEAL} pa hluav taws xob sib yuav muab khub cable + fais fab cable
- Kev kub ceev tau soj ntsuam kev kub ceev lub koob yees duab coaxpress + stigger kab ntsig kab coaxial kab + gpio kab
- Embedded AI Visual Ntug Kev Pom Yees Lub Koob Yees Duab Mipi CSi -2 + gpio synchronizes ffc flexible wiring
6. Kev ceev faj
- Qhov hnyav thiab qhov chaw: ntau dhau los yog dhau ntev ntev yuav cuam tshuam qhov kawg thiab kev ruaj khov ntawm cov drone.
- Raws li kev sib piv tau: Txheeb xyuas tias lub davhlau tswj system txhawb cov koob yees duab sib txuas lus (piv txwv li UCC, genicam).
- Thaum tshav kub dissipation: muaj zog cuam tshuam (xws li coaxpress) yuav tsum xav txog kev tsim cua sov dissipation.
- Redundant Backup: Dual Link (xws li U HDMI + USB) tuaj yeem siv los tiv thaiv cov teeb liab cuam tshuam rau hauv cov haujlwm tseem ceeb.
Los ntawm kev xaiv tsim nyog ntawm kev cuam tshuam thiab cov cable, kev sib koom ua ke ntawm cov koob yees duab thiab cov drones tuaj yeem ua tiav cov ntaub ntawv tau txais ntawm cov xwm txheej sib txawv.
