Ukukhiqiza kanye ne-PCBA yokulawula i-UAV eqondiswa yi-Fiber

Ukulawulwa kwe-UAV okuqondiswa yi-fiber kuyisifundo esivela ngqo kubuchwepheshe be-anti-tank missile obuqondiswa yi-wire - izinhlelo lapho umqhubi eqondisa khona isibhamu ngesixhumanisi esibonakalayo, engathinteki ekucindezelweni komsakazo kanye nokunqatshelwa kwe-GPS ngenxa yemvelo yale medium. Uhlobo lwesimanje luthatha indawo yocingo lwethusi nge-single-mode optical fiber, lushintsha i-bandwidth elinganiselwe yokuqala kanye nokuthambekela ekuphazamisekeni kukagesi kokuxhumana kwe-gigabit-class kanye nokuthula okuphelele kwe-electromagnetic. I-PCB yokulawula i-UAV eqondiswa yi-fiber iyingxenye yomoya yalolu hlelo: ithola imiyalo yokuqondisa ngokubonakalayo kusuka kumqhubi, iyiguqulele ekuphumeni kokulawula indiza, iphatha i-sensor suite esebhodini, futhi ibuyisela ividiyo kanye ne-telemetry nge-fiber efanayo ekhishwa kusuka ku-canister njengoba ipulatifomu idlula phansi.

Okuhlukanisa leli bhodi nesilawuli sendiza esivamile akuwona amandla okucubungula kodwa izidingo zesikhombikubona sokubona ezihlanganiswe nezidingo zesikhathi sangempela ezinzima. Iluphu yomyalo wokuqondisa - kusukela ekufakweni komqhubi kuya ekunyakazeni kwe-actuator - kumele ivale ngaphakathi kwesikhathi sokuphendula kwe-aerodynamic sepulatifomu. Kuma-drone okuqapha anamaphrofayili okundiza ahamba kancane futhi ahlosiwe, ama-40-50 ms ayamukeleka. Kumapulatifomu asheshayo e-tactical enza ama-terminal maneuvers, isabelomali singase sibe ngaphansi kwama-10 ms. Lezi zidingo zesikhathi ziqhuba zonke izinqumo zokwakha: isikhombikubona se-fiber, ukukhetha kweprosesa, indlela yokukhipha i-actuator, kanye nokuziphatha okuphephile.

Thola Isilinganiso se-PCB Yokulawula Esiqondiswa yi-Fiber

Ifa: Kusukela ku-FOG-M kuya ku-Drones Yesimanje Eqondiswa yi-Fiber

I-missile ye-BGM-71 TOW (1970s) yayisebenzisa intambo yethusi eyayikhishwa kokubili kusuka kusiqalisi kanye ne-missile ngesikhathi sokundiza, kanye nezimpawu zokuqondisa ezidluliselwa phezu kwentambo. Ububanzi babunqunyelwe amandla okudonsa intambo kanye nokuncipha kwesignali kagesi - ngokuvamile ngaphansi kwamakhilomitha ama-4. Ngasekupheleni kweminyaka yama-1970 kanye nama-1980, izinhlelo zocwaningo lokuzivikela zahlola ukufaka esikhundleni sethusi nge-optical fiber ngezizathu ezimbili: i-bandwidth ye-gigabit ye-fiber isekela ukubuya kwevidiyo kusuka kukhamera kumuntu ofuna i-missile, kanye nokungavikeleki kwe-fiber ekuphazamisekeni kwe-electromagnetic kubhekane nokukhathazeka mayelana nezinhlelo eziqondiswa yintambo ezivinjwe yi-emitters ye-microwave enamandla amakhulu.

Uhlelo lwe-Fiber Optic Guided Missile (FOG-M) lubonise lo mqondo kodwa lwakhanselwa ngaphambi kokukhiqizwa. Ubuchwepheshe oluqinisekisile — olukhiphe i-fiber kusuka kokubili epulatifomu yokuqalisa kanye nesibhamu, ngemiyalo yokuqondisa okubonakalayo kanye nokubuyiselwa kwevidiyo — lwaba yisisekelo sezakhiwo ze-drone zesimanje eziqondiswa i-fiber. Umehluko oyinhloko ukuthi amapulatifomu anamuhla angama-drone kunokuba yizibhamu ezihamba ngakwesokudla: aphatha amakhamera nama-sensor suites e-ISR kunokuba abe yizibhamu ezivikelayo, angase azulazule kunokuba andize ngqo aye endaweni eqondiwe, futhi kwezinye izimo angatholakala futhi asetshenziswe kabusha.

I-PCB yokulawula yesimanje eqondiswa yi-fiber izuza ukwakheka kwesignali okuyisisekelo okuvela ku-FOG-M — i-optical command forward, i-video return, i-passive fiber dispensing — futhi iyivumelanisa namaphrofayili okundiza e-drone, ukwakheka kwe-processor yamanje, kanye nokutholakala kwe-fiber optical yezentengiselwano kanye nobuchwepheshe be-transceiver ngezindleko ezazingekho ngawo-1980.

Ukwakhiwa Kwesistimu kanye Nendima Yebhodi

Uhlelo oluqondiswa yifayibha luqukethe: isiteshi somhlaba (i-opharetha ikhonsoli + ikhoyili yefayibha + umthumeli/isamukeli esibonakalayo) → ifayibha ekhishwayo → i-PCB yokulawula emoyeni → ama-actuator okundiza + ikhamera + umthwalo wenzwa. I-PCB yokulawula iyona kuphela i-interface phakathi komhlaba nomoya isikhathi sonke somsebenzi. I-interface yayo yokubona kumele yamukele imiyalo ngokuthembekile, iprosesa yayo kumele iyisebenzise ngesikhathi sangempela, futhi abashayeli bayo be-actuator kumele bakhiqize imiphumela ehlanzekile, ephansi yokubambezeleka ezindaweni zokulawula ukundiza noma kuma-motor.

Ngokungafani ne-drone eboshwe lapho i-fiber iphathwa khona uhlelo lwe-spool oluqondiswe kabili, ipulatifomu eqondiswa yi-fiber ikhishwa kwi-canister ngokunganaki - i-fiber iyakhokha njengoba i-drone ihamba, futhi lapho i-canister ingenalutho, ukuxhumana kuyaphela. I-interface ye-canister electronics iphathwa kwi- fiber optic canister PCB , eqapha i-fiber esele, ukucindezeleka kumhlahlandlela wokuphuma, kanye nesilinganiso sokusabalalisa. I-PCB yokulawula ithola idatha yesimo kusuka ebhodini le-canister ngebhasi eliphakathi kwamabhodi futhi isebenzisa lokhu ngezinqumo zokuphatha umsebenzi.

Ukuhlukaniswa kwebhodi: eminye imiklamo ihlanganisa isikhombikubona se-optical, iprosesa, okukhiphayo kwe-actuator, kanye nokuqapha i-canister ebhodini elilodwa. Ezinye zihlukanisa isikhombikubona se-optical ebhodini lokuxhumanisa idatha ye-optical elizinikele elixhunywe ebhodini lokulawula ngesixhumi esinejubane eliphezulu. Indlela ehlanganisiwe isindisa isisindo kanye nenani lezixhumi. Indlela yokuhlukanisa ivumela ukwenziwa ngcono okuzimele kwesikhombikubona se-optical se-analog-heavy kanye nomsebenzi wokulawula wedijithali-heavy, futhi ingenza kube lula i-EMC phakathi kwalezi zibili.

Indlela Yomyalo Wesiqondiso kanye Nesabelomali Sokubambezeleka

Iluphu yokuqondisa isebenza: okokufaka komqhubi → isofthiwe yokulawula umhlaba → ukufaka ikhodi kwe-optical → i-fiber → isamukeli se-optical esisemoyeni → ukuguqulwa kukagesi → ukuqopha iphrothokholi → ukuqinisekiswa komyalo → ukuphuma kwe-actuator → impendulo ye-aerodynamic → isithombe sekhamera → ukufaka ikhodi kwevidiyo → ukudluliselwa kwe-optical → i-fiber → isamukeli somhlaba → isibonisi. Ingxenye yale luphu ephethwe yi-PCB yokulawula — kusukela ekutholeni kwe-optical kuya ekuphumeni kwe-actuator — kumele ilingane nesabelomali sesikhathi sokubambezeleka, esisethwe isikhathi sokuphendula kwe-aerodynamic sepulatifomu ngaphandle kokulibaziseka kwefayibha yokuxhumana nokubuya (akunakwa ngobude be-tether ngaphansi kwamakhilomitha ayi-10: ~50 µs/km indlela eyodwa ku-c/n ≈ 0.67c).

Izinhloso zokubambezeleka eziqondene nepulatifomu:

• I-drone eqapha kancane (3–5 m/s, amaphiko amakhulu): isabelomali esiphelele seluphu 80–150 ms; isabelomali se-PCB sokulawula ~20–40 ms
• I-drone ye-Tactical ISR (10–20 m/s, ukuguquguquka okumaphakathi): isabelomali esiphelele seluphu 40–80 ms; isabelomali se-PCB sokulawula ~10–20 ms
• Ipulatifomu yokuqondisa esheshayo (>20 m/s, ukuguquguquka okuphezulu): isabelomali esiphelele se-loop <30 ms; isabelomali se-PCB <8 ms; sidinga ukulawula okusekelwe ku-FPGA okuzinikele

Ukubambezeleka ngaphakathi kwe-PCB yokulawula kuphethwe yi: ukuguqulwa kwe-optical-to-electric (~1 µs, okuncane), i-frame protocol receive buffer kanye ne-CRC check (~50–200 µs kuye nge-protocol kanye ne-processor), i-actuator interface (isikhathi se-PWM = 1/frequency; ku-400 Hz, ukubambezeleka okuphezulu kwe-PWM kungu-2.5 ms; i-DSHOT digital protocol yehlisa lokhu kube ngu-~100 µs).

Ukuhlolwa kobuqotho bomyalo kuyimpoqo: uhlaka ngalunye olutholiwe kumele lufake i-CRC noma i-checksum eqinisekiswa yiprosesa ngaphambi kokudlulisela umyalo kokukhiphayo kwe-actuator. Umyalo owonakele owenziwe ngaphandle kokuqinisekiswa ungakhiqiza okokufaka kokulawula indiza okungazange kukhishwe yi-opharetha. Ukuhlolwa kwe-CRC kunezela ama-µs angama-~5–20 ekucubungulweni kokubambezeleka — okwamukelekayo ngokuphelele ngenxa yendima yayo ekuvimbeleni imiyalo ye-actuator engamanga.

Umongo womklamo wokulwa nokujikijela kufanele uqashelwe lapha: ngoba imiyalo ihamba phezu kwefayibha, usongo lokujikijela kwe-RF oluqhuba umklamo we-PCB wokulwa nokujikijela alukho nhlobo. Imodeli yosongo lokuphepha yezinhlelo eziqondiswa yifayibha iwukusika ifayibha ngokomzimba, ukuvinjelwa ngokomzimba kwebhokisi lendle - hhayi i-electromagnetic.

Impendulo Yenzwa kanye Nendlela Yokubuyisa Ividiyo

Ividiyo kanye ne-telemetry zibuya nge-fiber efanayo nge-wavelength division multiplexing (WDM). Uhlelo olujwayelekile: luya phambili ku-1310 nm, ukubuya kwevidiyo ku-1550 nm. Ama-wavelength amabili abelana ngentambo efanayo ye-fiber kodwa ahlukaniswe ekugcineni ngakunye ngama-WDM optical couplers (ama-wavelength-selective beamsplitters). Lo mklamo we-bidirectional-on-one-fiber ubalulekile kumapulatifomu aqondiswa yi-fiber ngoba i-fiber iyasatshalaliswa futhi ayikwazi ukuba yi-multi-strand bundle - isisindo kanye nomthamo we-canister kudinga i-fiber eyodwa.

Ipayipi levidiyo ebhodini elihamba emoyeni: inzwa yekhamera → I-ISP (iprosesa yesignali yesithombe) → injini yokucindezela (i-H.264 noma i-H.265 hardware encoder) → ukupakisha → i-optical transmitter. I-1080p60 engacindezelwanga idinga ~3 Gbps; ngemuva kokufaka ikhodi ye-H.264 ezingeni lekhwalithi elifanele ukubhekwa, ukusakaza okufanayo kungaba yi-10–50 Mbps. Ukucindezela kuyimpoqo kunoma iyiphi ipulatifomu eqondiswa yi-fiber ene-canister esebenzayo ngoba ivumela ukusetshenziswa kwe-100 Mbps kuya ku-1 Gbps optical interfaces kune-10 Gbps, kanye nokunciphisa okuhambisanayo kwezindleko ze-transceiver, ukusetshenziswa kwamandla, kanye nobunzima bokuklama ibhodi.

Ipayipi levidiyo lilandela izimiso ezifanayo zokwakheka kwengqimba ebonakalayo njengebhodi lokuxhumanisa idatha ye-optical elizinikele , elilungiselelwe indawo yomshini we-dispensed-fiber — ikakhulukazi, i-engeli yokuphuma kwe-fiber kanye nanoma yikuphi ukungezwani okulethwa yindlela yokusabalalisa kungabangela ukuhlanganiswa kwemodi ku-multimode fiber, ngakho-ke ama-transceivers ahambisana ne-fiber yemodi eyodwa kanye nama-wavelength ayindlela ejwayelekile.

Ukuqapha Ukusabalalisa I-Fiber

Ibhodi lokulawula liqapha amapharamitha amathathu okusabalalisa, kungaba ngokuqondile noma ngebhodi lokuxhumana le-canister:

1. Amandla okubona ku-receiver: isibonakaliso esiyisisekelo sobuqotho befayibha. Ukwehla kwamandla ngokuzumayo kubonisa ukuphuka; ukwehla kancane kancane kungase kubonise ukwephulwa kwerediyasi yokugoba emzileni okhishiwe noma ukungcola emhlahlandlela wokuphuma.
2. Isilinganiso sefayibha esisele: okususelwa ekuhlanganisweni kwejubane (∫v dt) uma kuqhathaniswa nomthamo we-canister olinganisiwe. Izindlela ezinembile kakhulu zisebenzisa i-rotary encoder ku-exit spool noma inzwa yobude be-fiber eqondile. Isexwayiso se-fiber ephansi ku-10-20% esele sibangela ukubalwa komzila wokubuyela emuva.
3. Ukucindezeleka emhlahlandlela wokuphuma: i-strain gauge noma i-force sensor kumhlahlandlela wokuphuma ithola ukubanjwa — ukubanjwa kwe-fiber endaweni noma isithiyo kudala ukushuba okukhulu ngaphambi kokuba i-fiber iphuke. Ukutholwa kunikeza isexwayiso esingu-~50–200 ms, isikhathi esanele sokuzama isenzo sokugwema kwezinye izinkundla.

Zonke izinhlaka ezintathu kumele zithathwe amasampula ngesivinini esanele ukusekela i-logic ye-failsafe kuSigaba 6. Ukusampula kwamandla okubonakalayo ku-1 kHz kuyinto evamile — lokhu kunikeza isixazululo esingu-1 ms sokuthola ukuphuka. Ukusampula kokucindezeleka ku-500 Hz kwanele. Ukulinganisa ifayibha esele kungasebenza ku-10–50 Hz njengoba ukuchithwa kwe-canister kuyinqubo ehamba kancane uma kuqhathaniswa nomjikelezo wokulawula. Izindlela zehadiwe zokusabalalisa zichazwe kabanzi ebhokisini lokusabalalisa ifayibha kumongo we-PCB.

Umklamo Ongaphephile Wokulahlekelwa Yifayibha

Umshini wokuthola ukulahleka kwefayibha:

1. Amandla okubona awela ngaphansi komkhawulo we-T_low (setha u-3 dB ngaphezu kokuzwela okuncane kakhulu kwe-receiver)
2. Isibali sikhathi sokuqala: iwindi elingu-100–500 ms (lihlukanisa ukulahlekelwa okwesikhashana nokuphuka okuhlala njalo; ukulahlekelwa okwesikhashana kungenzeka ngesikhathi sokuhamba okubukhali okucindezela i-engeli yokuphuma kwefayibha)
3. Uma amandla ebuya ngaphakathi kwefasitela: umcimbi welogi, qhubeka nokusebenza, umqhubi wesaziso
4. Uma amandla engabuyi: memezela ukuphuka kwefayibha, qalisa imodi yokuphepha

Izinketho zemodi ye-Failsafe (kulungiselelwe kusengaphambili ngohlobo lomsebenzi):

• Ukujikeleza okuzenzakalelayo: ukushintshela ku-GPS esebhodini noma ukubamba kwe-barometric, ukuzulazula endaweni yamanje, ulinde umzamo wokuxhuma kabusha komqhubi nge-RF backup (uma ifakwe)
• Ukubuyela ebhodweni: zulazula uye endaweni yokugcina yebhokisi lemithi eyaziwa ngokuthi i-IMU dead reckoning, zama ukuxhuma kabusha i-fiber
• Ukunyakaza kwetheminali: kwezinhlelo zokusebenza zezibhamu, sebenzisa indlela yokugcina ehlelwe kusengaphambili ukuze uthole izixhumanisi eziqondiwe zokugcina ezaziwayo
• Ukwehla okulawulwayo: uma ukundiza okuzenzakalelayo kungenzeki, yehlisa izinga lokwehla elilawulwayo bese usika ama-motor lapho eseduze nomhlaba.

I-hardware watchdog iyimpoqo: i-watchdog timer ezinikele i-IC (hhayi isoftware watchdog) iqapha isignali yokushaya kwenhliziyo yeprosesa. Uma iprosesa ikhiywa — ngenxa yephutha le-firmware, i-EMI-induced latch-up, noma i-power glitch — i-watchdog iqinisekisa i-failsafe relay futhi iqhube ama-actuator esimweni esiphephile esichazwe ngaphambilini ngaphakathi kwesikhathi sokuvala se-watchdog (ngokuvamile ama-50–200 ms). Lona umugqa wokugcina wokuzivikela phakathi kokwehluleka kweprosesa kanye neplatifomu engalawulwa.

Ukukhethwa kweprosesa kanye ne-RTOS

I-PCB yokulawula idinga iprosesa ekwazi ukwenza umsebenzi ngesikhathi sangempela. Ama-metric abalulekile yi-interrupt latency embi kakhulu (ukubambezeleka phakathi kwephakethe lomyalo engenayo elibangela ukuphazamiseka kanye nokuqala kokusebenza komkhuba wesevisi yokuphazamiseka) kanye nesikhathi sokushintsha komongo (isikhathi sokulondoloza isimo somsebenzi samanje nokulayisha umsebenzi omusha). I-Jitter kulezi metrics inezela ngqo kwisabelomali se-control loop latency.

Izigaba zeprosesa:

• I-ARM Cortex-M7 (isb., STM32H7): I-480 MHz, i-hardware FPU, ukubambezeleka kokuphazamiseka okubi kakhulu ~ imijikelezo eyi-12 (~25 ns), okwanele kumapulatifomu adinga i->5 ms control loop. Isebenza kahle, isetshenziswa kabanzi kubalawuli bezindiza ze-drone zezentengiselwano. Ifanelekela amapulatifomu amaningi okuqapha aqondiswa yi-fiber.
• I-ARM Cortex-R5: I-lockstep dual-core yezinhlelo zokusebenza ezibalulekile zokuphepha, isikhathi sokuphendula esinqunyiwe, ukumangala okungenakho ukubambezeleka kwe-cache. Ikhethelwe amapulatifomu okuvikela lapho umsebenzi wokulawula indiza udinga ukuhambisana nezinga lobuqotho bokuphepha (SIL).
• Ukulawula okusekelwe ku-FPGA (i-Xilinx Zynq, i-Intel Cyclone): Kumapulatifomu adinga izihibe zokulawula ze-sub-millisecond, indwangu ye-FPGA isebenzisa i-algorithm yokulawula ngendlela eqondisiwe ene-deterministic one-clock-cycle latency. Iprosesa (i-ARM core ngaphakathi kwe-SoC) iphatha imisebenzi engeyona yesikhathi sangempela: ukuqopha i-telemetry, ukuqapha impilo ye-fiber, ukuphathwa kwemishini.

Ukukhethwa kwe-RTOS: I-FreeRTOS iyindlela evame kakhulu yokulawula i-drone efakiwe ngenxa yendlela yayo encane yokunyathela, ukuhlela imisebenzi eqinisekile, kanye ne-ecosystem ebanzi. I-Zephyr ithola ukwamukelwa kwezakhiwo zayo zesimanje kanye nokusekelwa kwezinhlaka zesitifiketi sokuphepha. I-Bare-metal (engenayo i-RTOS) iyamukeleka kumapulatifomu alula lapho i-control loop iwukuphela komsebenzi obalulekile, kodwa inezela ubunzima njengoba isethi yezici ikhula.

Ukwakhiwa Kwamandla Kwamapulatifomu Asetshenziswa Kanye

Amapulatifomu aqondiswa yi-fiber asebenzisekayo abhekene nomkhawulo wokwakhiwa kwamandla ongasebenzi kuma-drone angasetshenziswa kabusha: uhlelo lwamandla kumele lulungiselelwe iphrofayili yomsebenzi owodwa (ukuhamba kuze kube sekupheleni kwe-fiber), ngaphandle kwesidingo sokuphathwa kokujikeleza kokushaja noma impilo yebhethri yesikhathi eside. Lokhu kuvumela ukukhethwa kwamaseli okunamandla: amaseli e-polymer e-lithium akhipha kakhulu anamazinga aphezulu e-C angafinyeza impilo yomjikelezo ngokungamukeleki epulatifomu engasetshenziswa kabusha afaneleka ngokuphelele lapha.

Ukusatshalaliswa kwamandla kwe-PCB yokulawula kumele kuphathe ukwanda kwamandla okuqalisa kwenjini (ama-amps angamakhulu amaningana kuma-UAV amancane) ngaphandle kokudiliza i-voltage yokunikezela ngaphansi komkhawulo onsundu weprosesa. Umthamo omkhulu eduze kokufakwa kwamandla kwe-ESC ngayinye, kuhlanganiswe nezindiza zamandla ezihlukene zokushayela kwenjini kanye nama-avionics (axhunywe endaweni eyodwa yenkanyezi), kuvimbela umsindo wokushintsha kwenjini ukuthi ungahlangani nezinto zikagesi zokulawula.

Ukuqapha ibhethri: ukubalwa kwe-coulomb kunikeza isimo sokushaja sokuphathwa komsebenzi. Kumapulatifomu angasetshenziswa, ukukhathazeka okuyinhloko ukuqedwa komsebenzi ngaphambi kokukhishwa, hhayi isikhathi eside sebhethri - ijika lesimo sokushaja liqhuba i-logic yokubuyela ekhaya noma yokuyeka umsebenzi kanye nesilinganiso se-fiber esisele. Izimiso zokuklama i-PCB ye-drone enqatshelwe yi-GPS zokusatshalaliswa kwamandla ezindaweni eziphikisanayo zisebenza ngokufanayo lapha - ukungabikho kokukhathazeka nge-GPS jamming akususi isidingo somklamo wokunikezwa kwamandla oqinile we-EMI ngaphakathi kwe-avionics bay.

Okuqondiswayo vs. Okuboshiwe: Umehluko Wokuklama

Ukukhiqiza kanye Neziqu

Indlela yokukhiqiza ihlukaniswa ngemodeli yokusetshenziswa kabusha kwepulatifomu:

Amapulatifomu asebenzisekayo: I-FR-4 ejwayelekile, izendlalelo ezingu-4–6, izingxenye zezinga lokuhweba, i-SMT assembly ezenzakalelayo, i-100% in-circuit test (ICT) kanye nokuhlolwa kokusebenza, ukuhlolwa kwemvelo okwenziwe ngamasampula. Ukufaneleka kungokuhlaziywa komklamo kanye nokuhlolwa kwemvelo okulinganiselwe kunokuhambisana okugcwele kwe-MIL-STD-810. Izindleko yizona ezibangela inkinga enkulu - ipulatifomu ebhujiswe kanye ayikwazi ukuthwala ibhodi lesifunda elingu-$50,000. Ukwenziwa kwe -PCB ye-FR-4 ene-standard lead-free assembly kuhlangabezana nesidingo sokuthembeka sephrofayili yomsebenzi elinganiswa ngamahora.

Amapulatifomu e-ISR angasetshenziswa kabusha: Asondela ekuklanyweni nasekuqinisekisweni kwezinga lezempi — i-polyimide noma i-substrate ye-FR-4 ephezulu ye-Tg, ukwamukelwa kwe-IPC Class 2 noma 3 assembly, i-conformal coating yokumelana nomswakama kanye nokungcola, ukuhlolwa kwe-MIL-STD-810 environmental qualification. Ukuhlolwa kokusebenza kufaka phakathi: i-guidance command loopback ekushiseni okuphezulu kokusebenza, i-fiber break simulation (i-optical attenuator efakiwe ukuqinisekisa i-failsafe triggers kahle emkhawulweni ochaziwe), ukulinganisa i-latency kuyo yonke indlela yomyalo ogcwele.

I-Highleap inikeza ukwenziwa nokuhlanganiswa kwamabhodi okulawula aqondiswa yi -fiber angasetshenziswa futhi, kanye namaphakheji emibhalo afanele izinga ngalinye lokufaneleka.

Imibuzo Evame Ukubuzwa

I-drone eqondiswa yi-fiber ingandiza ibanga elingakanani?
Ububanzi bunqunyelwe umthamo we-canister — ubude be-fiber engafakwa ku-canister ekugcineni komoya, kanye ne-fiber ekhoneni eliseceleni komhlaba. Umthamo we-canister osebenzayo emoyeni ungamakhilomitha angu-5–20 ku-canister enesisindo esingu-2–8 kg. Amanye amapulatifomu amakhulu athwala amakhilomitha angaphezu kuka-30. Isabelomali sesixhumanisi se-optical akuyona into evimbelayo — i-fiber yemodi eyodwa engu-1310 nm ku-0.35 dB/km enesabelomali se-optical esingu-20 dB sisekela amakhilomitha angu-57, sidlula kakhulu umthamo we-canister.

Ingabe ukwakheka okuqondiswa yi-fiber kungasekela ukuzulazula kwe-waypoint okuzenzakalelayo?
Yebo — ukuzulazula okuzenzakalelayo kusebenza kuprosesa engaphakathi futhi akudingi isixhumanisi se-fiber ukuze kuqaliswe ukusebenza. Isixhumanisi se-fiber siphethe imiyalo yokudlulisa umqhubi futhi sibuyisela ividiyo ukuze kuqwashiswe ngesimo. Izindlela ezizimele zibaluleke kakhulu kumapulatifomu aqondiswa yi-fiber ngoba umqhubi angase alahlekelwe yividiyo okwesikhashana (ngenxa yendawo efihla ikhamera) ngenkathi ipulatifomu iqhubeka nokuhamba ngokuzimela.

Kwenzekani uma i-fiber iphuka ekugcineni komhlabathi (eduze kwe-coil)?
Isenzakalo sokulahlekelwa yi-optical sifana ngokombono webhodi elisemoyeni kungakhathaliseki ukuthi i-fiber iphuka kuphi. Ukutholwa kanye nomqondo wokuphepha ochazwe kuSigaba 6 kusebenza ngokulinganayo ekuphukeni kwe-ground-end ngokuphathelene nokuphukeni kwe-air-end. Ngokomzimba, ukuphukelwa kwe-ground-end kungase kuvame kakhulu - i-fiber eduze kwendawo yokuqalisa ayimi futhi isengozini yokunqunywa yithrafikhi yezimoto noma abasebenzi.

Ukunqatshwa kwe-GPS kuyithinta kanjani le nqubo?
Ngendlela yokuxhumana ngefayibha: akunjalo nhlobo. Isixhumanisi sefayibha asikwazi ukuminyana noma ukuphamba kwe-GPS. Kwimodi yokuzimela ye-failsafe: kakhulu. Uma i-failsafe ithembele ekubuyeleni ekhaya okubhekiselwe ku-GPS, ukuminyana kwe-GPS kukhubaza le nketho. Ngakho-ke, amadizayini agxile ekuvikeleni asebenzisa i-IMU kuphela njengemodi yokuzimela eyinhloko, ne-GPS njengenketho yesibili uma itholakala. I-PCB ye-drone enqatshelwe i-GPS umongo womklamo ubhekana nehadiwe yokuzulazula engenamsebenzi esekela leli khono.

Cela ikhodi
