Kev faib tawm ntawmDroneVideoTxuas
Yog tiasUAV video transmissionsystem yog cais raws li hom kev sib txuas lus mechanism, feem ntau nws muaj peev xwm muab faib ua ob pawg: analog uav kev sib txuas lusqhov systemthiab digitaluavyees duabtransmitterqhov system.Analog video kis tau tus mob yog hais txog cov txheej txheem ntawm qhov chaw thiab channel ua ntawm analog video signals nrog kev hloov pauv tsis tu ncua hauv lub sijhawm (xws li qhov chaw) thiab amplitude, thiab kis tau los ntawm cov channel analog lossis khaws cia los ntawm cov khoom siv kaw lus analog.Digital Uavideodatalink yog hais txog cov txheej txheem uas cov digital video signals raug xa mus los ntawm digital channels (cables, microwaves, satellites thiab optical fibers, thiab lwm yam) los ntawm qhov chaw coding thiab channel coding, los yog khaws cia los ntawm digital cia thiab kaw cov cuab yeej.
Analog Drone Video Txuas VS Digital Drone Video Transmitter
| Analog Drone Video Link | Digital Drone Video Transmitter | |
| Teeb liab | Lub teeb liab analog yog lub teeb liab txuas ntxiv.Nws cov tsis muaj peev xwm sawv cev rau ntau yam kev ntsuas lub cev uas yuav tsum tau kis | Lub teeb liab digital yog lub teeb liab tau txais los ntawm kev hloov lub sij hawm txuas ntxiv analog teeb liab mus rau lub sij hawm-discrete sampling nqi. |
| Wua aveform | sine yoj | sine yoj |
| Txoj kev nthuav qhia cov ntaub ntawv | Cov ntaub ntawv yog sawv cev los ntawm cov txiaj ntsig sib law liag | Cov ntaub ntawv yog sawv cev los ntawm cov nqi tsis tu ncua |
| Technology | Sau cov duab ntawm lub waveform | Ua piv txwv cov qauv waveform analog thiab sau qhov loj ntawm waveform txhua lub sijhawm |
| Cov ntaub ntawv | ● Khaws rau hauv daim ntawv waveform ● Kev tsim tawm tsis zoo ●Quality degrades raws sij hawm thiab tus naj npawb ntawm kev hloov | Khaws cia li binary cov ntaub ntawv, luam thiab kho tsis cuam tshuam cov ntaub ntawv zoo |
| Bandwidth | Analog teeb liab ua tiav tuaj yeem ua tiav hauv lub sijhawm, siv tsawg dua bandwidth | Kev ua cov teeb liab muaj kev ua haujlwm tsis zoo hauv lub sijhawm thiab siv ntau bandwidth |
| Hwj chim | Siv zog ntau dua | Tsawg zog siv |
| Kev siv peev txheej | Tus nqi qis, yooj yim Circuit Court | Tus nqi siab, complex Circuit Court |
| Hardware thiab Circuit Court | Cov kev xav tau ntawm cov khoom siv thiab cov khoom siv hluav taws xob muaj siab, thiab kev ua haujlwm tau yooj yim cuam tshuam los ntawm cov txheej txheem sib txawv.Yog li ntawd, qhov zoo ntawm analog video kis tau tus mob nyob rau hauv lub lag luam nws txawv. | Vim qhov digitization ntawm lub teeb liab analog, qhov kev ua txhaum ntawm lub Circuit Court yog siab heev, thiab kev sib kis tau ruaj khov thiab txhim khu kev qha.Yog li ntawd, nws tsis rhiab rau qhov sib txawv ntawm cov khoom siv thiab cov circuits. |
| Kev xa cov ntaub ntawv thiab teb rau suab nrov | Vim lub superimposition ntawm lub suab nrov thiab cov ntaub ntawv muaj txiaj ntsig, nws yuav cuam tshuam los ntawm lub suab nrov hauv txhua qhov txuas thaum lub sijhawm sib kis thiab tsis tuaj yeem tshem tawm tag nrho.Nws yuav txo cov teeb liab-rau-suab nrov piv raws li tus naj npawb ntawm cov kev sib txuas ntxiv (lub teeb liab yuav tsuas yog zuj zus thiab zuj zus).Lub analog video kis tau tus mob tsis tuaj yeem tsuas ua kom lub zog kom ua tiav lub hom phiaj ntawm kev nce qhov sib kis. | Lub suab nrov tsis cuam tshuam rau cov ntaub ntawv xa mus, thiab feem ntau ntawm cov suab nrov tuaj yeem lim tawm los ntawm software kom tshem tawm cov suab nrov.Kev ntseeg tau ntawm cov ntaub ntawv xa mus tuaj yeem lav tau los ntawm kev txheeb xyuas cov thev naus laus zis sib txawv nyob rau theem tom ntej.Tsis tas li ntawd, cov ntaub ntawv digital kuj tseem yooj yim rau kev nkag mus, kom cov ntaub ntawv tsis pub lwm tus paub tau zoo heev. |
| Kev siv tau | Cov ntaub ntawv kaw tseg yuav raug cuam tshuam los ntawm ib puag ncig sab nraud xws li kev kaw qhov tseeb. | Cov teeb liab video yog lub teeb liab digital, uas yooj yim rau sau thiab tseem pab txhawb kev sib txuas rau ntau yam digital interfaces.Thiab lub teeb liab tuaj yeem ua tiav nrog cov cuab yeej siv niaj hnub. |
| Daim ntawv thov | Analog ntaus ntawv | Cov khoos phis tawj thiab cov khoom siv digital |
| Cov qauv | Xov tooj cua, xov tooj | Videophone, rooj sib tham TV |
Cov teeb liab digital tuaj yeem tsim tawm ntau zaus yam tsis muaj kev poob zoo thaum sib kis.Nws kuj muaj cov yam ntxwv ntawm kev tuav tau yooj yim, hloov tau yooj yim, kev ua haujlwm siab, kev ruaj ntseg thiab kev ntseeg tau, thiab kev saib xyuas yooj yim, uas yog superior rau analog kis tau tus mob.Yog li ntawd, kev xa cov yeeb yaj kiab digital feem ntau yog siv rau hauv cov ntawv thov kev lag luam.
●Kev sib xyaw ntawmUAV video transmission system
Hauv qhov xwm txheej ntawm UAV daim ntawv thov, qhov ntev ntawm uav cov ntaub ntawv txuas nyob rau ntawm lub dav hlau platform feem ntau hu uacua tshuab, thiab cov video kis tau tus mob nyob ntawm qhov chaw tswj hauv av hu ua avchav tsev.Kev sib txuas lus kev taw qhia ntawm ib-txoj kev loj code kwj cov ntaub ntawv yog los ntawm huab cuachav tsevrau hauv avchav tsev.
●Kev xaiv lub koob yees duab ntev drone transmitter thiab receiver
Tam sim no, muaj ntau qhov sib txawv uav xov tooj cua sib txuas lus modules ntawm lub khw, tab sis cov khoom zoo tsis sib xws.Seb puas muaj cov cuab yeej tseem ceeb uas tuaj yeem sawv qhov kev sim ntawm kev ua lag luam yog qhov tseem ceeb.IWAVE's point-to-point wireless video thiabwireless telemetry moduleyog ua raws li kev tshawb fawb txog kev txawj ntse thiab kev tsim kho, tshwj xeeb yog tsim rau kev lag luam-theem kev siv, thiab tuaj yeem siv dav hauv drones, hauv av neeg hlau, UGV, ROV thiab lwm yam kev sib txuas lus tsis muaj neeg siv.
