Yini okwenza ukuthi i-Drone Jammer Backpack ibe yindlela efanele kakhulu yokuphulukisa ngokukhawuleza?

Ukufika kwezindawo zokusebenza ngokushesha nokubhekana nendlela yokusebenza ngokuphelele

Ukusebenza kwezindawo zokuphulukisa ukuthi amathuba ayisisekelo akhona kusobala ngokushesha kakhulu—okuyinto ephakanyiswa ngokungafanele. Isikhombisa sokugcina izilwane zokudlula i-Drone Jammer Backpack kufanele alinganise ukuvikelwa okuqinile nokunyakaza okulula: izinto ezihlanganisiwe ezinamandla amakhulu, ezinesisindo esincane (isb., inayiloni eliqinisiwe elinomkhombandlela we-carbon fiber) zinciphisa ubuningi ngaphandle kokudela ukuqina. Amabhande amahlombe agudluziwe, alungisekayo kanye nephaneli yangemuva enomoya ohlanzekile, enama-contour ahlukanisa isisindo ngokulinganayo futhi anciphise ukukhathala ngesikhathi sokuthwala isikhathi esideokubalulekile lapho opharetha kufanele bagijime, benyuke izitebhisi, noma bahambe endaweni engalingani Izingxenye zokufinyelela okusheshayo ezibekwe ngendlela efanele ukuze zithole isandla esiyinhloko ezivumela ukusetshenziswa kweyunithi yokuvala ingcindezi ngaphansi kwengcindezi yesikhashana esingaphansi kwemizuzwana emihlanu. Izinsimbi ezihlanganisiwe zokufaka imoto kanye nezinsimbi zokumunca ukushaqeka zigcina uhlelo luphephile ngesikhathi sokuhamba, kuyilapho ukuxhumeka kwamachweba amaningi (i-USB-C, i-Ethernet, i-MIL-STD-1553 enqunyiwe) kuvumela ukuhlanganiswa ngokushesha namapulatif Lezi zici eziqinisekiswe ekuhlolweni kwensimu okujwayelekile kweNATOazikho lula kodwa zenza amandla aphindwe kabili aguqula ukuhamba kube yinzuzo yokusebenza.

Isikhathi Sokusebenza Kwesibhakabhaka Nokuthula Kwesibhakabhaka Ngokuphelele Kwe-Drone Jammer Backpack

Ukulungela umsebenzi okuqhubekayo kuxhomeke ezintweni ezimbili eziyinhloko ezihlobene: amandla amabhethri nokuqina kokushisa. Izindinganiso zomkhakhakuhlanganise nalezo ezibekwe nguMnyango Wezokuvikela wase-U.Si-Counter-UAS Interoperability Profile (CUAS-IOP)zidinga isikhathi esincane sokuvala i-2.5 amahora ngokuqhubekayo ngokushaja ngaphansi komthwalo we-RF ophezulu. Ukufeza lokhu kudinga amaseli e-lithium-sulfur noma e-silicon-anode Li-ion anobuningi bamandla obungu-450 Wh/kg, ahlanganiswe nokuphathwa kwamandla okuhlakaniphile okukala amandla okusebenza ngokuya ngobuningi besongo. Ukuphumelela okushisayo kubalulekile ngokulinganayo: izingxenye kufanele zisebenze ngokuthembekile phakathi kuka-20°C no-+60°Cindawo ephelele yemvelo echazwe ku-MIL-STD-810H. Ukupholisa okusebenzayo ngokusebenzisa ama-ventilator angenawo umsindo, angenamabhulashi ahlanganiswe nama-spreaders okushisa egumbi lomphunga kugcina amazinga okushisa okuhlangana ngaphansi kuka-75 °C ngesikhathi sokusebenza okuqhubekayo, kuvimbela ukulahleka kwamandla angama-40% + okuhambisana nokuqhutshwa kok Lokhu kugxila kokubili ekuqineni kwamandla nokuqina kokushisa kuqinisekisa ukusebenza okuzinzile, okunganqunywa hhayi kuphela ema-laboratory alawulwayo, kodwa nasemihumeni yokushisa ehlane, ukusatshalaliswa e-Arctic, kanye nemisebenzi yasogwini enomswakama.

Isiphakade Sokujamela Esinephakade Nokuthembeka Kwesikhathi Somlando Ngemilayezwe Emihle

Ukuphumelela kwemisebenzi kuyapha kancane ngokulinganisa isiphakade esithethekile kodwa kubaluleke ukujamela okubaluleke nokusebenza isiphakade sokujamela ngemilayezwe yezinsizakalo, izinkundla zokugcina isibonelo esingqondile—lapho iziwave zokugcina zokufika kuzo zihambisana nezifunda zokugcina zokufika ngokwesibonelo, kusindisela ukujamela okuhle. Izisigodi zesikhathi samandla zisikhuba lezi zinkundla ngokusebenzisa izihloko zokujamela zokuphambuka noma zokuphambuka ngokuvamile ezinhliziyo zokujamela okuvamile okuzokuthintela izinye izinyathelo zokujamela kuzo zokugcina zokufika kuzo futhi kuzokuthintela amandla kumathuba okutholakala. Ukuboniswa kwemilayezwe yezinkundla eBerlin, eSingapore, neChicago akubonisa ukuthi izinhlelo eziphambuka ziyasebenza kahle kusukela ku-500 mita kwezinhlelo zokujamela okunempela—nangona kunezinkundla eziningi nezinkundla zokugcina zokufika kuzo zokugcina zokufika kuzo—kuzokuthintela ukuthenga kwezinhlelo zokujamela ngokushesha emasimini okutholakala. isiqhameko izihloko zokujamela zokuphambuka noma zokuphambuka ngokuvamile ezinhliziyo zokujamela okuvamile okuzokuthintela izinye izinyathelo zokujamela kuzo zokugcina zokufika kuzo futhi kuzokuthintela amandla kumathuba okutholakala. Ukuboniswa kwemilayezwe yezinkundla eBerlin, eSingapore, neChicago akubonisa ukuthi izinhlelo eziphambuka ziyasebenza kahle kusukela ku-500 mita kwezinhlelo zokujamela okunempela—nangona kunezinkundla eziningi nezinkundla zokugcina zokufika kuzo zokugcina zokufika kuzo—kuzokuthintela ukuthenga kwezinhlelo zokujamela ngokushesha emasimini okutholakala.

Ukuphikisa Ukugcina Kwezinkundla Zokugcina Zokufika Kuzo Nokugcina Kwezinyathelo Zokufika Ngokwesibonelo

Izimo zokungabonwa ngokwesibonelo (NLOS) nezikhumba zemibili ziyizindlela zokuphula kwe-RF emazweni. Ukuphakanyiswa kwamaphethini akakhali ukuthi kubeka isinyathelo esiphansi—kuyabuka ukukhulula kwe-phase okuhlinzekile ukusobala kwe-jamming. Izinkulumo ezintsha zikwenzela lokhu ngokusebenzisa ukwahlukaniswa kwe-polarization (ukuthumela ngokwesibonelo esihlukene nesihlukene) nokufiltera kwe-digital okuzivimba okuvumela ukuthi kubonwe nekukhululwa amaphethini asekhaya ngokushesha. Ukuthayela kwe-frequency-hopping spread spectrum (FHSS) kuyenza lezi zinkulumo zibe nzima kakhulu: ngokuthayela phakathi kwezinkambo ezingaphezu kwe-20 ngosekondi, isistimu ayisobala izibandela zokuphula—njengazo zokugcina kwe-Wi-Fi yezindaba noma izincelulo zocellular. Emasimini amahle asebenzayo emazweni ngokwesifundo sika-EN 301 893, lezi zinkulumo zazikhubaza i-87% yezinhlobo zokujama kwezindawo zokuvula—kubonisa ukuthi kunezinhlobo ezinamandla kakhulu zokujama kwezindawo zokuvula.

Ukuhlanza kwezinhlobo zokuphula kwezindawo ezingu-200ms ukusukela ekuboneni kuya ekukhululweni

Kodwa kufundwa kwezindawo zokuphatha izi-drones ezingakwazi ukuziphatha—ikakhulu izi-drones ezinamandla, ezincane kwezinsuku—ukungabi nesikhathi sokubuyela kuyisibonelo. Izibhanki zezinkolelo ezinamandla zihlanganisa izengini zokuthola ezisebenzisa i-radio esiyifundisa ngomthwalo (SDR) ezinokwenza umhlangozi wokugcina wonke umkhosi ngobude bebandwidth ye-100 MHz nobukhulu be-resolution ye-12-bit. Ngokuthola izilinki zokuphatha kwezidrone ezingavumelekile (ngokusebenzisa ukuchaza kwezilinki zokuphatha ngokubona isigaba se-RF, ukususa umbhalo wokuphatha, noma ukuchazana kwezilinki zokuphatha ngokuchazana kwe-radar cross-section), isistimu isiqale ukujama ngokuvamile ngaphansi kwe-≤195 ms—kodwa phansi kwesikhathi se-200 ms esivumelwe yi-DHS CISA’s Counter-UAS Test Protocol. Izimboni zokuhlola ngaphandle kwezizwe zika-UK Home Office’s National Protective Security Authority zavumela ukuthi kutholakala ukuthola kwezidrone ezingavumelekile ngokuphathelene ne-98% kwezindlela zokuphatha ezingabhekisele kwezinsuku zokuphatha kwe-300-meter safety perimeter. Le yisikhathi esingaphansi kwe-200ms—kusha kuthola kuya kujama kwe-RF—yilokho esihlinzekile kuhlanganisa ukuphatha okuphambili nokuphatha okuphambili.

Ukusebenza okunamandla nokuphatha ngokushintsha kanye ngokushintsha kokushintsha kwezindawo zokuphatha eziningi ezinamandla

Kumaziko okuphakeme kakhulu—izindlu zokubhukuda ezinamaphuzu, izimo zokubhukuda ngokusebenzisa izihlangu, amaphutha weVIP—abasebenzi abangafanele bakwazi ukuthi kunezinkinga zokusebenzisa isikhombiso. Isikhwama sokujabula izihlangu esithunywa ngendlela yokuphulukana kahle sifuna ukuthi sisebenze ngaphandle kokufundwa . Ukuvula ngokuchofoza okukodwa kuqala amaphrofayli asongelwayo (isb., Quadcopter Lockdown noma FPV Drone Suppression) ngaphandle kokuzulazula kwemenyu. Izikhombi zinezinkinobho ezihlukile, ezikhanyiswe ngemuva, ezihambisana neglavu; impendulo yesimo ihlanganisa ama-LED anekhodi yombala namathoni omsindo anengqondo (isb., ukukhuphuka kwephimbo = ukwanda kwamandla okuphazamisa). Isixhumi esibonakalayo silandela izimiso zokuklama ezigxile kumuntu ze-ISO 9241-210, ezingekho ngaphezu kwezendlalelo ezintathu eziphakeme futhi azinaso isidingo sokungena kwesikrini sokuthinta ukuqinisekisa ukusebenza emvuleni, othulini noma ezimweni zokukhanya okuncane. Lokhu akukhona ukululama okulimaza amandla; kungukwakhiwa okuhlosiwe okubeka ukusebenza okubalulekile emsebenzini ngaphakathi kokufinyeleleka okungokwemvelo ukuze abasebenzi bezokuphepha, abaxhumanisi bezenzakalo, noma abaphendula kuqala benze ngokuzimisela, ngaphandle kokungabaza.
