i-cofdm yomkhosi isidluliseli sophawu esingenazingcingo
Isiqulatho
Yintoni i-cofdm yasemkhosini yokuhambisa umqondiso ngaphandle kwamacingo?
Umthumeli womkhosi we-COFDM sisixhobo esinokuthumela kwaye sifumane imiqondiso yomsindo kunye nedatha usebenzisa i-COFDM. (Ikhowudi ye-Orthogonal Frequency Division Multiplexing) ubuchule bokumodareyitha kwedijithali. COFDM iteknoloji efanayo DVB-T eYurophu digital tv umgangatho, enokucinezela ngempumelelo ividiyo kunye neaudio kwi-TS umjelo nge-encoder kunye nemodyuli, kunye ne-receiver ene-decoder kunye ne-demodulator chipset, inokufumana ngokugqibeleleyo ividiyo ephilayo yokwenyani, audio, kunye nedatha evela kumthumeli ukuya kumamkeli.
Le ndlela yenza umqondiso uxhathise ngakumbi ukuphazamiseka, ingxolo, kunye nokuncipha, iyenza ilungele izicelo zomkhosi.
Umgama wothumelo lwesignali engenazingcingo yecofdm yomkhosi
I-COFDM iyafana nezikhululo zikamabonakude zedijithali. Logama nje i-transmitter ibekwe phezulu ngokwaneleyo kwaye ngaphakathi komgca wokubona, kwaye akukho miqobo kumthumeli kunye nomamkeli, inokuxhasa imigama ukusuka 1 km ukuya 200 km.
| PA | THE | NLOS |
| 500MW | >10Km | <300m |
| 1W | >30Km | <500m |
| 5W | >60Km | <1500m |
| 20W | >120km | <3000m |
| 50W | >200Km | <5000m |
| 100W | >250Km | <10Km |
Isidluliseli soMkhosi se-cofdm esingenazingcingo
- Lixabiso
- kokulinganisa low
- Ukusebenza lula
- oluNgabonakaliyo
- Inkxaso yokutshintsha rhoqo ukunqanda i-jammer
Iintlobo zesidlulisi sophawu lomkhosi cofdm ezingenazingcingo
engambi: Yeyona modeli inexabiso eliphantsi, sicinga ukuba ezinye ii-transmitter zifakwe kwiidrones, kwaye zisenokubetha imithi okanye eminye imiqobo nangaliphi na ixesha zize ziwe. Kuba zitshiphu, zinokuthengwa ngobuninzi kwaye zisetyenziswe njengezinto ezidliwayo. Ukuba ilahlekile, zinokutshintshwa. Umamkeli unokulungiswa kunye nezinye ii-transmitter ukuze ziqhubeke zisetyenziswa. COFDM-912T, Buza iinkcukacha ngalo mzekelo. 
uqhagamshelwano lwetshiphu emsebenzi 1080P: Imodeli efikelelekayo engentla ixhasa kuphela isisombululo se-720P kunye ne-CVBS igalelo lekhamera edibeneyo. Ukuba uneemfuno eziphezulu zokulungiswa kwevidiyo, unconywa i-COFDM-908T nge-HDMI igalelo kunye nemveliso yokuxhasa i-1080P. I-COFDM-908T, Buza iinkcukacha ngalo mzekelo.
ILatency ephantsi: Yezinye ii-UAV ezinobungakanani obuphakathi nezinkulu, ixabiso lokwenziwa kwenqwelo-moya liphezulu noko, kwaye i-transmitter kufuneka yenziwe nge-ultra-low latency. Ukulibaziseka kweenkqubo eziqhelekileyo zokuhanjiswa kwevidiyo ezingenazingcingo ziya kufikelela kwi-200 ~ 400 milliseconds, kodwa inkqubo yokuhanjiswa kwevidiyo engenazingcingo esezantsi kakhulu inokufikelela kuma-30 ~ 40 millisecond., elungele kakhulu i-drones enesantya esiphezulu kunye neendleko eziphezulu zokuqinisekisa Iyakwazi ukubona imiqobo ngexesha kwaye yenze uhlengahlengiso oluhambelanayo.. Vcan1729, Buza iinkcukacha ngalo mzekelo.
lwetshiphu + CVBS zombini iikhamera zevidiyo: Kwezinye iidrones okanye ezinye iimeko zokhuseleko, iikhamera ezimbini zifakiwe, efuna ukuba umthumeli wethu abe nako ukusasaza iividiyo ezimbini ngaxeshanye. Kubathengi abanale mfuno, ungakhetha wethu Vcan1726., Buza iinkcukacha ngalo mzekelo.
Imveliso ye-Ethernet RTSP kwikhompyuter: Abanye abathengi bakwafuna ukuba umamkeli akakwazi nje ukuvelisa imifanekiso kwimonitha eqhelekileyo kodwa akhuphe imifanekiso kwikhompyuter ngexesha lokwenyani.. Kule meko, umamkeli kufuneka abe nemveliso yezibuko yenethiwekhi exhasa i-ONVIF kunye ne-RTSP protocol. Unokudlala ividiyo ephilayo yomqalisi usebenzisa isidlali seVLC. Vcan1726, Buza iinkcukacha ngalo mzekelo.
Ugqithiso loMqondiso / Ukuphinda / Extender: Kwezinye izicelo ezizodwa, njengaxa kukho izakhiwo, iintaba, okanye imithi evalela umqondiso, sinokubeka iirelays embindini wemiqobo yokwandisa umgama wothumelo kunye nokwandisa amandla omqondiso wothumelo.. UVcan 1870, Buza iinkcukacha ngalo mzekelo.
Isisombululo semfuno ye-transceiver yeendlela ezimbini: Wonke umntu uyazi ukuba i-CFODM yinkqubo yosasazo yendlela enye enokusasaza ividiyo, audio, kunye nedatha evela kumthumeli ukuya kumamkeli, kodwa ayinakubonelela ngophazamiseko lwesignali okanye impendulo yepakethe. kunjalo, ukuze kusonjululwe iimfuno zabathengi zothumelo lweendlela ezimbini, Iinjineli zisenokwenza iiseti ezimbini ze-COFDM transceiver systems zibe nye, ukuze isidluliseli sibe nomsebenzi womamkeli, kwaye umamkeli unomsebenzi wothumelo. Le yi-transceiver ye-COFDM. UVcan 1886, Buza iinkcukacha ngalo mzekelo.
Umsebenzi wokusasaza we-UDP: Vcan1816, Buza iinkcukacha ngalo mzekelo.
