Emkhakheni obushintsha ngokushesha wezobuchwepheshe bezempi, izinhlelo zokuvikela ezomsindo sezibe yingxenye ebalulekile emisebenzini yezokuphepha emoyeni. Uhlelo lokuqaphela umsindo (ARes) olwakhiwe yiWenfei Summit luseqhulwini lale nkululeko, lunikeza amakhono okuvikela ezomsindo ashukumisayo enzelwe ngokukhethekile ukuthola nokulawula izindiza ezingenamuntu (UAV). Ukusebenzisa ukutholwa komsindo okuthuthukile nobuchwepheshe be-phased microphone array, i-ARes ihlinzeka ngokuqapha okuphelele okungu-360-degree nokuhlola okusheshayo kwezinsongo, iqinisekisa ukuvikelwa okungcono kakhulu ngokumelene nokungena okungagunyaziwe kwezindiza ezingenamuntu.

Uhlelo lokuvikela lwe-ARes acoustic luyenziwe ngobuchwepheshe besimanjemanje obusebenzisa amandla e-beamforming—indlela egxilisa ukwamukela kwezinzwa zezwi ezindaweni ezithile ukuze kuthuthukiswe ukucaca kwesiginali nokunemba kokutholwa. Lesi sici sivumela i-ARes ukuthi ihlukanise phakathi kwezinsongo zangempela ze-UAV nemisindo yendawo ezungezile, kunciphisa kakhulu ama-alamu amanga. Umklamo ohlangene wesistimu uhlanganisa izinhlobonhlobo eziningi zamalungu omakrofoni, okuyivumela ukuthi ikhombe imithombo yomsindo ngokunemba okungajwayelekile. Amandla ayo okushintsha iziphumo ze-beamforming ngokuzenzakalelayo aqinisekisa ukuzivumelanisa nezimo ezahlukahlukene zokusebenza, kusukela ezindaweni zasemadolobheni kuye ezinkundleni zempi ezivulekile.

Ngaphezu kwalokho, uhlelo luhlanganisa izindlela eziyinkimbinkimbi zokucubungula amasiginali ezihlaziya imisindo eyenza ihluke kumamodeli ahlukahlukene ama-UAV. Ngokuqhathanisa le misindo nedatabase ebanzi, i-ARes ingakwazi ukuhlukanisa futhi ibeke phambili izinsongo ngempumelelo. Isigaba sokuthuthukiswa sigcizelele nokuqina kanye nokulula ukusetshenziswa, siqinisekisa ukuthi uhlelo lungamelana nezimo ezinzima ngenkathi luhlala lusebenza kahle ezimweni ezahlukahlukene zempi.

I-ARes ihamba phambili ekuhlinzekeni ngokuqapha komoya okuphelele ngokukwazi kwayo ukuthola okuzungezayo okungu-360-degree. Lokhu ukubuyekezwa okubandakanya konke kubalulekile ezindaweni zempi zesimanje lapho izinsongo zingavela kunoma yisiphi isiqondiso. Uhlelo luthola ngempumelelo ama-UAVs kumabanga ahlukahlukene, luhlinzeka ngezixwayiso zakuqala ezivumela izinyathelo zokulwa ngesikhathi. Izinzwa zayo ezilalelwayo zizwela ngokwanele ukubona imisindo yama-drone ethule kumabanga amade, kuthuthukisa ukuqonda kwesimo kwabasebenzi bezokuvikela.

Umsebenzi wokulandelela wesistimu ngesikhathi sangempela uvumela ukuqapha okuqhubekayo kwezindlela zama-UAV. Uma ihlanganiswa nezinqubo ezihlanganisiwe zokwazisa, i-ARes yenza lula izinqubo zokuphendula ezisheshayo, kufaka phakathi ukuthunyelwa kwezinqubo zokulwa nge-elektroniki noma ukwazisa amabutho asemhlabeni. Lokhu kulungela ukusebenza kuqinisekisa ukuthi amayunithi ezempi angagcina ukuphepha komoya ngengozi encane yokuhlaselwa okungazelelwe noma ukuphulwa kokuhlola.

Ukuze kuqhakazelwe amandla ezokuvikela ezomsindo e-ARes, kusekelwa ubuchwepheshe bayo be-phased microphone array. Lezi zinhlelo zihlanganisa ama-microphone abekwe ngobuhlakani athwebula amagagasi omsindo avela eziqondisweni ezahlukahlukene. Ngokuhlaziya umehluko wesikhathi lapho umsindo ufika khona ku-microphone ngayinye, uhlelo lubala indawo eqondile yomthombo womsindo. Le ndlela yokuhlunga isikhala ithuthukisa isilinganiso sesignali-kuya-umsindo, ivumela ukuhlukaniswa phakathi kwama-drone neminye imisindo ezungezile njengezinyoni, izimoto, noma imisindo yesimo sezulu.

Ama-algorithm athuthukileyo ohlelo ahlaziya ngokuqhubekayo amaphethini wemvamisa kanye nemisindo eyenzeka ngezinhlelo zokudonsa ze-UAV. Le khono lokuthola imisindo eyihlukile kubalulekile ukuhlukanisa ama-drone ayingozi kwezinto ezindizayo ezingenawo ubungozi. Ngaphezu kwalokho, i-ARes isebenzisa amamodeli wokufunda komshini aqhubeka nokuphucula ukunemba kokuthola ngokuhamba kwesikhathi ngokufunda kusuka kudatha entsha yomsindo, ngaleyo ndlela ihlale ingaphambili kwezobuchwepheshe ze-UAV eziguqukayo.

Ukuhlolwa kokulwa okukhulu kuqinisekisile ukusebenza kwe-ARes ezindaweni ezahlukene zokusebenza. Ukuhlolwa kwasemfield kwenziwe ezimweni ezahlukene zezulu nezendawo, kuveze ukuzethemba kwalesi system ekutholeni nasekulandeleni ama-UAV phakathi kwezimo zokukhuluma eziyinkimbinkimbi. Isibonelo, ngesikhathi sokuzama ukuvikela umngcele, i-ARes yathola ngempumelelo ukuhlaselwa kwe-drone okuningi, inikeza izaziso zokuqala ezavumela amaqembu okuphanga ukuthi aphonse izinsongo ngokushesha.

Impendulo evela kubasebenzi bezempi igcizelele ubuchwepheshe obuqondile be-ARes kanye nezinga eliphansi lokukhala okungamanga, kugcizelela izinzuzo zayo ezisebenzayo ezimeni eziphakeme zokucindezela. Ukuthwala kwalesi system kanye nesikhathi esisheshayo sokusetha nakho kwavuma, kwenza kube kufanelekile ukuyisebenzisa kokubili ezindaweni ezimisiwe nasezindaweni ezihambayo. Lezi zihlolo eziphumelelayo ziqinisekisa indima ebalulekile ye-ARes ekwandiseni amakhono okuvikela emoyeni lapho ukunemba nokuphendula ngesikhathi kubalulekile.

Bheka phambili, iWenfei Summit ihlela ukwandisa iphothifoliyo ye-ARes acoustic defense system ngokuthuthukisa izinhlobo ezincane nezilula ezihloselwe ukuhamba ngokushesha nokuhlanganiswa nezinkundla zempi ezikhona. Lezi zinguquko zihlose ukunciphisa izinyathelo zokuhamba nokuthuthukisa ukuhamba kokusebenza, ikakhulukazi kumajoni akhethekile kanye namathimba aphendula ngokushesha.

Ukwandiswa okuqhubekayo kufaka phakathi ukuhlanganisa i-ARes nobuchwepheshe bezinzwa obuhambisanayo njengeradar ne-infrared ukuhlinzeka ngamakhono okuthola izindlela eziningi. Le ndlela yokuhlanganisa izinzwa izokwandisa kakhulu ukunemba kokutholwa kwezinsongo kanye nokumelana nezinyathelo zokulwa. Ngaphezu kwalokho, ucwaningo oluqhubekayo lugxile ekuthuthukiseni ukusebenza kahle kwamandla ohlelo kanye nezici zokuxhumana okungenantambo ukusekela imisebenzi yasenkundleni yesikhathi eside ngokugcinwa okuncane.

Ukuzibophezela kweWenfei Summit ekuqambeni izinto ezintsha kubonakala ekutshalweni kwawo njalo ocwaningweni lobuchwepheshe bezomsindo. Ubuchwepheshe babo ezinhlelweni zomsindo ezikhomba ibanga elide, njengoba kuchazwe ku-MAYELANA NATHI ikhasi, iqinisa isikhundla sabo njengabaholi kwezixazululo zokuvikela ezomsindo. Iphothifoliyo yabo ihlanganisa izicelo kwezokuphepha komphakathi, ukuphathwa kwezimo eziphuthumayo, kanye nokuphepha kwezempi, okugcizelela ubuchule babo kwezokuxhumana ezomsindo.

I-Acoustic Reconnaissance System (ARes) yona imele intuthuko enkulu kwezobuchwepheshe bokuzivikela ngomsindo, ihlanganisa ubunjiniyela obunembayo ne-signal processing ehlakaniphile ukuze kuvikelwe ezintweni ezintsha ezihlasela emoyeni. Ngokuhlanganisa ukutholwa okuphelele kwe-UAV, ukuhlukanisa imithombo yomsindo, nokusebenza okuqinile, i-ARes ithuthukisa ukulungela kwezempi nokuqonda kwenkundla yempi. Umklamo wayo omusha kanye nokusebenza kahle okukhonjisiwe ezimeni zokulwa kwenza kube yimpumelelo ezinhlelweni zokuphepha emoyeni.

Njengoba ubuchwepheshe be-UAV buqhubeka nokuthuthuka, kufanele kube njalo nezokuvikela ezibamelana nabo. Ukuzibophezela okuqhubekayo kwe-Wenfei Summit ekuthuthukiseni i-ARes nokwandisa amakhono ayo kuqinisekisa ukuthi amabutho ezempi ahlala enezixhobo zesimanje ukuze avikele isikhala sezindiza. Ezinhlanganweni ezithanda izixazululo eziphambili zokuphepha komsindo, ukuhlola uhla olubanzi lwezinto ezihlinzekwa yi-Wenfei Summit ku- IMIKHIQIZO ikhasi linikeza ukuqonda okubalulekile ngezobuchwepheshe ezihambisanayo ezithuthukisa isu lokuvikela jikelele.
