Kev soj ntsuam ntawm Fiber Optic Remote Control Technology thiab kev siv ntawm Unmanned Aerial Vehicles
Tso lus
Lub hauv paus ntawm lub drone tej thaj chaw deb maub los lub fiber optic module nyob rau hauv nws siv lub cev kho qhov muag fibers es tsis txhob ntawm xov tooj cua electromagnetic nthwv dej, tsim ib tug siab -ceev thiab ruaj khov "hardwired" kev sib txuas lus channel zoo tsis cuam tshuam los ntawm electromagnetic cuam tshuam.
Cov lus hauv qab no qhia txog qhov sib piv tseem ceeb ntawm qhov no thiab ib txwm siv wireless chaw taws teeb tswj txoj hauv kev:
Cov ntsiab lus tseem ceeb: Yuav ua li cas kom tau txais Fiber Optic Kev Sib Txuas Lus
Cov thev naus laus zis ntawm fiber ntau optic kev sib txuas lus module yog photoelectric hloov dua siab tshiab thiab txuas kev tsim kho. Koj yuav tsum tsom mus rau cov hauv qab no:
1. Photoelectric Hloov Module
Qhov no yog qhov system "tus neeg txhais lus." Hauv av- sab module hloov cov chaw taws teeb tswj cov teeb liab hluav taws xob (xws li UART, SBUS) rau hauv cov teeb liab kho qhov muag; huab cua- sab module ua cov txheej txheem thim rov qab, kho cov teeb liab kho qhov muag rov qab rau cov teeb liab hluav taws xob rau lub davhlau tswj. Thaum xaiv ib lub module, koj yuav tsum xyuas kom meej tias nws theem interface (xws li 3.3V / 5V TTL) yog sib xws nrog lub davhlau maub los qhov chaw nres nkoj serial.
2. Fiber Optic Cable Xaiv
Hom: Xaiv raws li nyob deb. Tib hom - hom fiber ntau muaj cov tub ntxhais nyias nyias thiab qhov sib kis tau ntev heev (txog 10 mais lossis ntau dua), haum rau kev siv ntev - deb; multimode fiber ntau yog tus nqi qis - tab sis muaj qhov sib kis luv dua (feem ntau nyob rau hauv ob peb kilometers).
Parameters: Ua tib zoo saib xyuas qhov muaj nuj nqis attenuation (piv txwv li, qis dua 0.17 dB / km) thiab txoj kab uas hla. Txoj kab uas hla ncaj qha txiav txim qhov hnyav; Piv txwv li, 0.5mm fiber ntau hnyav kwv yees li 0.5 kg ib kilometer, yog li 10 kilometers yuav hnyav 5 kg, ua rau muaj kev sib tw tseem ceeb rau drone lub payload.
3. Flight Control Software Configuration
Tom qab kev sib txuas kho vajtse, qhov chaw nres nkoj serial txuas nrog fiber ntau optic module yuav tsum raug teeb tsa kom raug nyob rau hauv lub davhlau tswj tsis tau. Feem ntau, serial chaw nres nkoj raws tu qauv yuav tsum tau teem rau MAVLink (rau kev sib txuas lus nrog rau hauv av chaw nres tsheb) los yog lwm yam kev cai raws tu qauv, thiab ib tug baud npaum li cas piv rau fiber optic module (xws li, 115200 los yog siab dua) yuav tsum tau teem.
Kev txiav txim siab txog kev ua haujlwm: Kev xa tawm thiab kev ua haujlwm
Kev ua haujlwm tiag tiag ntawm fiber ntau optic module suav nrog kev xa tawm tshwj xeeb thiab cov txheej txheem ua haujlwm:
1. Kev sib txuas ntawm qhov system thiab xyuas
Cov kev sib txuas ua ke yog: Chaw Taws Teeb Tswj → Av - sab Optoelectronic Module → Fiber Optic Module → Ntuj - sab Optoelectronic Module → Davhlau Controller. Xyuas kom meej tias lub wireless duab / cov ntaub ntawv kis tau tus mob module ntawm sab drone yog neeg xiam oob qhab los tiv thaiv wireless teeb liab cuam tshuam nrog lub teeb liab fiber ntau.
2. Fiber Optic tswj thiab tso tawm
Qhov no yog qhov nyuaj tshaj plaws thaum ua haujlwm. Lub drone yuav tsum tau nruab nrog lub fiber optic winding mechanism (spool) thiab ib txhij tso cov fiber optic cable thaum lub davhlau. Qhov no yuav tsum tau lub tshuab ua kom yooj yim tso cov cable thiab muaj kev tswj nruj kom tiv thaiv cov fiber ntau optic cable los ntawm kev tawg vim ncab lossis ua tangled.
3. Redundancy thiab Emergency Design
Txhawm rau kom ntseeg tau tias muaj kev nyab xeeb, siab -kawg lossis tub rog tshuab siv dual-txuas txuas ntxiv tsim ntawm fiber ntau optic + xov tooj cua. Cov thawj fiber optic txuas yog siv nyob rau hauv ib txwm muaj xwm txheej; Yog hais tias lub fiber optic cable tawg, lub kaw lus tam sim ntawd thiab cia li hloov mus rau lub wireless backup txuas kom ntseeg tau tias lub drone tseem tswj tau.
Cov ntsiab lus tseem ceeb ua haujlwm: Nws ua tau thiab ua tsis tau
Nkag siab txog nws txoj haujlwm ua haujlwm yog ib qho tseem ceeb rau kev ntsuam xyuas seb puas yuav siv cov thev naus laus zis no.
Core Functional Advantages:
Kev khiav hauj lwm hauv Complex Electromagnetic Environments: Hauv cov cheeb tsam uas muaj zog electromagnetic cuam tshuam, xws li kev sib ntaus sib tua, siab -voltage power towers, thiab radar chaw nres tsheb, nws yog tib txoj kev sib txuas lus zoo.
Siab -Bandwidth Real-Lub Sijhawm Cov Ntaub Ntawv Xa Tawm: Nws tuaj yeem ruaj khov xa tawm siab- txhais lossis txawm tias 4K cov kwj video, ua tau raws li qhov xav tau ntawm cov xwm txheej uas xav tau siab- cov duab zoo, xws li kev tshawb nrhiav thiab tshuaj xyuas.
Kev sib txuas lus ruaj ntseg thiab ruaj ntseg: Lub teeb liab tsis tawm mus rau sab nraud, tshem tawm tag nrho qhov muaj peev xwm ntawm xov tooj cua tshawb pom thiab qhov chaw, muab kev ceev ceev heev.
Cov kev txwv tseem ceeb ntawm kev ua haujlwm:
Tsawg maneuverability: Lub drone lub zog yog nruj me ntsis txwv rau qhov ntev ntawm fiber optic cable, txwv tsis pub nws maneuverability.
Kev hloov pauv ib puag ncig siab: Thaum ya hauv hav zoov lossis nruab nrab ntawm cov tsev hauv nroog, fiber ntau optic cable tau yooj yim snapped, tso cov kev xav tau nruj ntawm kev npaj davhlau.
Ua kom lub cev muaj zog: Qhov hnyav ntawm fiber ntau optic cable thiab nws cov kev tswj hwm ua rau kom lub drone load, ncaj qha cuam tshuam nws endurance thiab maneuverability.
