tub rog cofdm wireless teeb liab transmitter
Cov Lus Qhia
Dab tsi yog tub rog cofdm wireless signal transmitter?
Cov tub rog COFDM wireless signal transmitter yog ib yam khoom uas tuaj yeem xa thiab txais cov suab thiab cov ntaub ntawv teeb liab siv COFDM (Coded Orthogonal Frequency Division Multiplexing) cov txheej txheem digital modulation. COFDM yog cov cuab yeej zoo sib xws rau DVB-T Europe cov qauv tv, uas tuaj yeem ua tau zoo compressed video thiab suab hauv TS kwj los ntawm encoder thiab modulator, thiab ntawm lub receiver nrog decoder thiab demodulator chipset, nws tuaj yeem tau txais cov yeeb yaj kiab nyob tiag tiag, suab, thiab cov ntaub ntawv los ntawm transmitter mus rau receiver.
Txoj kev no ua rau lub teeb liab tiv thaiv kev cuam tshuam, suab nrov, thiab fading, ua kom tsim nyog rau kev siv tub rog.
Tub rog cofdm wireless teeb liab transmitter kis nrug deb
COFDM yog tib yam li terrestrial digital TV chaw nres tsheb. Tsuav tus transmitter tso siab txaus thiab nyob rau hauv txoj kab ntawm qhov pom, thiab tsis muaj teeb meem rau lub transmitter thiab receiver, nws tuaj yeem txhawb kev deb ntawm 1 km rau 200 km.

Tub rog cofdm wireless signal transmitter Hom
Pheej Yig Heev: Rau tus qauv pheej yig tshaj, peb xav tias qee qhov transmitters tau nruab rau ntawm drones, thiab tej zaum lawv yuav tsoo ntoo lossis lwm yam teeb meem txhua lub sijhawm thiab ua rau lawv poob. Vim lawv pheej yig, lawv tuaj yeem yuav ntau thiab siv los ua khoom siv. Yog poob, lawv tuaj yeem hloov tau. Lub receiver tuaj yeem kho nrog lwm cov transmitters rau kev siv txuas ntxiv. COFDM-912T, Nug kom paub meej txog tus qauv no. 
HDMI 1080P: Cov qauv pheej yig dua saum toj no tsuas yog txhawb nqa 720P daws teeb meem thiab CVBS cov koob yees duab sib xyaw cov tswv yim. Yog tias koj muaj kev xav tau ntau dua rau kev daws teeb meem video, koj tau pom zoo COFDM-908T nrog HDMI cov tswv yim thiab cov zis los txhawb 1080P. COFDM-908T, Nug kom paub meej txog tus qauv no.
Tsawg tshaj latency: Rau qee qhov nruab nrab thiab loj UAVs, tus nqi tsim khoom ntawm lub dav hlau yog qhov siab, thiab lub transmitter yuav tsum tau ua nrog ultra-low latency. Qhov kev ncua sij hawm ntawm cov kab ke video wireless zoo tib yam yuav ncav cuag 200 ~ 400 milliseconds, tab sis ultra-low qeeb wireless video kis tau tus mob tuaj yeem ncav cuag qhov xav tsis thoob 30 ~ 40 milliseconds, uas yog qhov tsim nyog rau kev kub ceev thiab tus nqi siab drones kom ntseeg tau tias nws tuaj yeem ntes cov teeb meem hauv lub sijhawm thiab ua kom muaj kev hloov kho.. wb 1729, Nug kom paub meej txog tus qauv no.
HDMI + CVBS ob lub koob yees duab video: Hauv qee qhov drones lossis lwm qhov xwm txheej kev nyab xeeb, ob lub koob yees duab raug ntsia, uas xav kom peb lub transmitter muaj peev xwm xa ob cov yeeb yaj duab tib lub sijhawm. Rau cov neeg siv khoom nrog qhov kev xav tau no, koj tuaj yeem xaiv peb wb 1726., Nug kom paub meej txog tus qauv no.
Ethernet RTSP tso zis rau lub computer: Qee cov neeg siv khoom kuj xav kom lub receiver tsis tau tsuas yog tso tawm cov duab mus rau lub monitor tsis tu ncua tab sis kuj tso tawm cov duab rau lub computer hauv lub sijhawm.. Nyob rau hauv cov ntaub ntawv no, tus txais yuav tsum muaj lub network chaw nres nkoj tso zis uas txhawb ONVIF thiab RTSP raws tu qauv. Koj tuaj yeem ua si lub launcher cov yeeb yaj kiab nyob siv VLC player. wb 1726, Nug kom paub meej txog tus qauv no.
Teeb liab Relay / Repeater / Extender: Hauv qee daim ntawv thov tshwj xeeb, xws li thaum muaj vaj tse, roob, los yog ntoo thaiv lub teeb liab, peb tuaj yeem tso cov relays hauv nruab nrab ntawm cov teeb meem kom ncua qhov kev sib kis deb thiab nce lub teeb liab lub zog ntawm kev sib kis.. Xyoo 1870, Nug kom paub meej txog tus qauv no.
Kev daws rau ob txoj kev transceiver xav tau: Txhua tus paub tias CFODM yog ib txoj kev sib kis uas tuaj yeem xa cov yeeb yaj kiab, suab, thiab cov ntaub ntawv los ntawm transmitter mus rau receiver, tab sis nws tsis tuaj yeem muab cov teeb liab cuam tshuam lossis cov lus tawm tswv yim pob ntawv. Txawm li cas los, txhawm rau daws cov neeg siv khoom xav tau rau kev sib kis ntawm ob txoj kev, engineers kuj tuaj yeem ua ob pawg ntawm COFDM transceiver systems rau hauv ib qho, yog li ntawd lub transmitter kuj muaj kev ua haujlwm ntawm lub receiver, thiab lub receiver kuj muaj kev ua haujlwm ntawm lub transmitter. Qhov no yog COFDM transceiver. Xyoo 1886, Nug kom paub meej txog tus qauv no.
