Ngokuthuthuka okusheshayo kobuchwepheshe bezimoto zasemoyeni ezingenamuntu (i-UAV), izimo zokusetshenziswa kwazo ziye zanda kusukela ekuzijabuliseni kwabathengi kuya emisebenzini yezinga lezimboni, njengokuvikelwa kwezitshalo zezolimo, ukuthuthwa kwempahla, kanye nokuhlolwa kwamandla. Kodwa-ke, njengoba ukusebenza kwe-UAV kuqhubeka nokuthuthuka, izingozi zokuphepha ezingaba khona ziye zanda kakhulu. Phakathi kwalokhu, "into eyenzeka nge-spark" ezixhumanisweni zokuxhumeka kwebhethri ivele njengenkinga ebalulekile esongela ukusebenza okuphephile kwe-UAV. Ikakhulukazi kuma-UAV ezinga lezimboni, ahlonyiswe ngamabhethri anamandla aphezulu futhi asebenza ngaphansi kwemisinga ephezulu yokukhipha amandla—enemisinga esheshayo engase idlule i-300A—ama-arc kagesi akhiqizwa ngesikhathi sokuxhumana kwe-electrode awagcini nje ngokulimaza ama-terminals okuxhuma futhi anciphise isikhathi sokuphila kwemishini kodwa futhi abeka izingozi zezingozi ezinkulu njengokushiswa kwebhethri kanye nokwehluleka kwamandla endizeni. Ngokumelene nalokhu, izixhumi ze-anti-spark, ngokusebenza kwazo okuphezulu kokuvikela ukuphepha, ziye zaba yingxenye ebalulekile emishinini ye-UAV.
I. Ukubhekana Nobuhlungu: Kungani Isenzakalo Senhlansi Siba Ingozi Yokuphepha Kwezindiza Ezingenawo Ama-UAV
Ukwenzeka kokushaqeka ngesikhathi sokufakwa/ukususwa kwebhethri noma uxhumano lwesekethe kuma-UAV kuvela ngokuyinhloko emphumeleni we-capacitive ngaphakathi kohlelo lukagesi. Izingxenye eziyinhloko ezifana ne-flight control module kanye ne-electronic speed controller (ESC) yama-UAV zihlanganisa ama-capacitor amaningi. Uma ibhethri lixhunyiwe, lawa ma-capacitor ashaja ngokushesha, okudala i-initial loop impedance ephansi kakhulu. Lokhu kuphumela ekushaqekeni okusheshayo okudlula kakhulu amandla okusebenza ajwayelekile, okubangela i-air ionization ngaphansi kwethonya lamandla aphezulu kangaka bese kamuva kukhiqiza ama-arcs kagesi. Izixhumi zendabuko, ezingenazo imiklamo yokuvikela ephumelelayo, ziyahluleka ukumelana nokukhishwa okunjalo kwesikhashana kwe-high-voltage. Lokhu akuholeli nje kuphela ekushiseni okungapheli kanye nokwanda kokumelana kokuxhumana kodwa futhi kunezingozi zokubangela ukuqhuma kokushisa kwebhethri. Ngokwezibalo zemboni, izingozi zokuphepha kuma-UAV ezibangelwa ukushaqeka kwezixhumi zibangela ngaphezu kwama-25% ezehlakalo eziphelele, ezibangela ukulahlekelwa okukhulu kwezomnotho kubasebenzisi futhi zivimbele intuthuko enempilo yemboni ye-UAV.
II. Ukuthuthukiswa Kobuchwepheshe: Indlela Yokuvikela Eyinhloko Yezixhumi Ezilwa Nezinhlansi
Ukuze kuxazululwe inkinga yokuqhuma kwe-spark, izixhumi ezilwa ne-spark zisungule uhlelo lokuvikela ukuphepha oluphelele ngokusebenzisa ubuchwepheshe obuhlukahlukene:
Okokuqala, umklamo wesakhiwo sokuxhumana oyingqayizivele. Usebenzisa ukwakheka kokuxhumana okunezinyathelo "zokumelana kuqala, ukuhanjiswa kamuva". Lapho isixhumi sihlanganiswa, i-anti-spark resistor yenza ukuxhumana kuqala. Ngomgomo wokuhlukaniswa kwamandla okumelana, ugesi wokuqala wokungena uncishiswa ngaphezu kuka-60%, okuvimbela ngempumelelo i-ionization yomoya kanye nokukhiqizwa kwe-arc. Lo mklamo wesakhiwo unqamula indlela yokwakheka kwe-arc emthonjeni, okunikeza isithiyo sokuqala sokuphepha sokuxhumeka kwesekethe.
Okwesibili, ukusetshenziswa kwezinto ezisebenza kahle kakhulu. Lezi zixhumanisi zinenqubo yokufaka igolide enobukhulu bengqimba yegolide engu-3μm, engagcini nje ngokulawula ukumelana kokuxhumana okungaphansi kuka-5mΩ ukunciphisa ukukhiqizwa kokushisa ngesikhathi sokudluliselwa kwamanje kodwa futhi inikeza ukumelana okuhle kakhulu kokugqwala kanye nokumelana nokuguguleka. Indlu yenziwe nge-aluminium alloy yezinga lendiza, ifinyelela ukukhanya okulula (okulula ngo-40% kunezindlu zendabuko) ngenkathi ibekezelela ukudlidliza okunamandla kanye nokuguguleka okukhulu kwemvelo, okuqinisekisa ukusebenza okuzinzile kwesixhumi ngaphansi kwezimo zokusebenza eziyinkimbinkimbi.
Okwesithathu, ukuhlanganiswa kwamamojula okulawula ahlakaniphile. Imojula yokuqalisa kancane eyakhelwe ngaphakathi elawulwa yi-MCU ivumela inqubo ye-gradient yamanje yemizuzwana engu-0.5-2, evumela ukuthi ugesi ukhuphuke kahle kusuka ku-0 uye enanini elilinganisiwe, isuse ngokuphelele ingozi yokukhishwa kwe-voltage ephezulu yesikhashana. Isibonelo, izixhumi ze-TE Connectivity ezilwa ne-spark, zisebenzisa lobu buchwepheshe, zilawule amathuba okukhiqizwa kwe-arc ngaphansi kuka-0.01%, okuthuthukisa kakhulu ukuphepha kokusebenza kwama-UAV.
III. Ukuqaliswa Kwesimo: Izicelo Ezihlukahlukene Zezixhumi Ezilwa Nezinhlansi
Izimo ezahlukene zokusetshenziswa kwe-UAV zibeka izidingo zokusebenza ezahlukahlukene ezixhumini ezilwa ne-spark, okuqhuba ukuthuthukiswa kwemikhiqizo eyenziwe ngokwezifiso:
Emkhakheni wokuvikelwa kwezitshalo zezolimo, ama-UAV adinga ukushintshwa amabhethri awo njalo (ngokuvamile izikhathi eziyi-10-20 ngosuku), okubeka izidingo eziphezulu kakhulu esikhathini sokuphila kwe-plug-in kanye nokulula kwezixhumi. Isixhumi se-200A se-Hobbywing esilwa ne-spark sisebenzisa umklamo wokufaka i-snap-on okusheshayo, isikhathi sokuphila kwe-plug-in esingaphezu kwezikhathi eziyi-5,000 kanye nesisindo esingama-35g kuphela, esihambisana nezinhlelo zebhethri ze-14S high-voltage. Ekusetshenzisweni okungokoqobo, lesi sixhumi sinciphise ukwanda kokwehluleka kwe-ESC okubangelwa ama-arc kagesi kuma-UAV okuvikela izitshalo ngo-92%, okuthuthukisa kakhulu ukusebenza kahle kokusebenza.
Ezimweni zokuthutha ngezokuthutha, ama-UAV aphishekela ukusebenza kahle kokushintsha ibhethri "elisezingeni lemizuzu", okudinga kokubili ukudluliselwa kwamandla aphezulu kanye nokukhiqizwa kokushisa okuphansi. Isixhumi se-Pogo Pin se-Toplink esilwa ne-spark sisebenzisa umklamo we-shunt ohambisanayo wokuxhumana okuthathu. Ngaphansi kwamandla okusebenza angu-80A, ukunyuka kwezinga lokushisa lokugcina kungu-35K kuphela (okuphansi kakhulu kunezinga lomkhakha elingu-60K). Ngokuncika kulesi sixhumi, iziteshi zesisekelo ze-UAV ze-SF Express zingaqeda ukushintshwa kwebhethri elingama-10kW zingakapheli imizuzwana engu-45, inani lama-UAV ahlinzekwa nsuku zonke lidlula ama-500 okuthutha, okuhlangabezana nezidingo zokusebenza kahle kakhulu kwezokuthutha ngezokuthutha.
Ezimweni zokuhlola ezinobungozi obukhulu njengezinkundla zikawoyela negesi kanye namapaki amakhemikhali, ukusebenza okuvikela ukuqhuma kuba yimfuneko eyinhloko. Isixhumi esilwa nenhlansi esifakwe ku-DJI's M300RTK UAV sinomklamo wokuvala ovimbela ukuqhuma, onesilinganiso sokuvikelwa esingu-IP68. Singagcina amandla e-plug-in azinzile kanye nokusebenza kokuvikela ezindaweni ezibucayi kusukela ku--40℃ kuya ku-85℃, futhi sidlule isitifiketi sokuvikela ukuqhuma se-ATEX, senza kube lula ukusetshenziswa okuphephile ezindaweni eziyingozi zeSigaba II futhi siqede izingozi zokuphepha ezibangelwa yinhlansi.
IV. Izitayela Zesikhathi Esizayo: Ukuthuthukiswa Kwezobuchwepheshe Okunika Amandla Intuthuko Yomnotho Osezingeni Eliphansi
Njengoba izinqubomgomo ezihlobene nomnotho osezingeni eliphansi zisetshenziswa kancane kancane, izimo zokusetshenziswa kwe-UAV zizoba yinkimbinkimbi kakhulu, okudala izidingo eziphakeme zobuchwepheshe bokuxhumanisa i-anti-spark:
Ngokusebenza kahle, amandla okuthwala ugesi azodlula ku-300A. Okwamanje, ubuchwepheshe be-nanocoating buzosetshenziswa ukuthuthukisa ukumelana nokuguguleka kokuthintana, kwandise isikhathi sokuphila kwe-plug-in sibe ngaphezu kwemijikelezo engu-200,000 ukuze kuhlangatshezwane nezidingo zokusebenza kwesikhathi eside, okunamandla aphezulu. Ohlangothini lobuhlakani, izixhumi zizohlanganisa izinzwa zokushisa kanye namamojula okuqapha amanje ukuze zinikeze impendulo yesikhathi sangempela ngezimo zokusebenza futhi ziqalise ngokuzenzakalelayo ukuvikelwa kokucima ugesi uma kwenzeka kuba nokungahambi kahle. Isibonelo, izixhumi ezihlakaniphile ze-Amphenol ezilwa ne-spark zingadlulisela idatha ohlelweni lokulawula indiza ngebhasi le-CAN, zivumele isixwayiso sangaphambi kwesikhathi futhi zithuthukise ukusebenza kokuphepha kwe-UAV.
Ngaphezu kwalokho, ukulungiswa kwe-SWaP (Usayizi, Isisindo, kanye Namandla) sekuyindlela ebalulekile yokuthuthukiswa. Ukwamukelwa kwezithasiselo ezintsha ze-thermoplastic kanye nezinqubo zokubumba ezihlanganisiwe kuzonciphisa ivolumu ngo-30% kanye nesisindo ngo-25% ngenkathi kuthuthukiswa amandla omkhiqizo. Izixhumi ezincane ezilwa ne-spark ezakhiwe abakhiqizi basekhaya, ezinevolumu eyingxenye nje yemikhiqizo yendabuko, zingashintshwa zibe yi-UAV encane yabathengi, zikhulule isikhala esengeziwe semithwalo yemishini.
Nakuba zincane ngobukhulu, izixhumi ezilwa ne-spark zidlala indima ebalulekile ekuqinisekiseni ukusebenza okuphephile kwama-UAV. Kusukela ekuvikelweni kwezitshalo zezolimo kuya ekuthuthweni kwezinto kanye nokuhlolwa okuyingozi kakhulu, ukuphindaphinda kwazo kwezobuchwepheshe bekulokhu kuhlobene kakhulu nentuthuko yemboni yama-UAV. Esikhathini esizayo, ngokuthuthukiswa okuqhubekayo kwezobuchwepheshe, izixhumi ezilwa ne-spark ngeke zisebenze nje kuphela "njengesithiyo sokuphepha" sama-UAV kodwa futhi zizobe ziyisisekelo ezinhlelweni zokuphathwa kwamandla, zivikele intuthuko yekhwalithi ephezulu yomnotho ophansi.
