Bitewe n’iterambere ryihuse ry’ikoranabuhanga ry’indege zitagira abapilote (UAV), uburyo zikoreshwa bwagiye buva ku kwidagadura ku rwego rw’abaguzi kugeza ku bikorwa by’inganda, nko kurinda inganda z’ubuhinzi, gutwara ibikoresho, no kugenzura ingufu. Ariko, uko imikorere ya UAV ikomeje gutera imbere, ingaruka zishobora guterwa n’umutekano zarushijeho kugaragara. Muri ibyo, "ibintu bitera ubwoba" mu guhuza bateri byagaragaye nk'ikibazo gikomeye kibangamiye imikorere myiza ya UAV. By’umwihariko kuri UAV zo mu rwego rw’inganda, zifite bateri zikoresha ingufu nyinshi kandi zikora munsi y’imigezi myinshi isohora amazi—hamwe n’imigezi ihita irenga 300A—imirongo y’amashanyarazi ikorwa mu gihe cy’ikoranabuhanga rya electrode ntiyangiza gusa ibyuma bihuza ibyuma kandi ikagabanya igihe cyo kumara ibikoresho ahubwo inateza ibyago by’impanuka zikomeye nko gutwika bateri no kubura kw’amashanyarazi mu kirere. Muri iki gihe, imiyoboro irwanya umuriro, hamwe n’imikorere yayo myiza yo kurinda umutekano, yabaye igice cy’ingenzi mu bikoresho bya UAV.
I. Guhangana n'ikibazo cy'ububabare: Impamvu ikintu cy'ubusa kigira ingaruka mbi ku ndege zitagira umuvuduko
Kuba hari umuriro uturuka mu gihe cyo gushyiramo/gukuraho batiri cyangwa guhuza uruziga muri UAV bituruka ahanini ku ngaruka zo gukoresha ingufu mu buryo bw'amashanyarazi. Ibice by'ingenzi nka module igenzura indege na electronic speed controller (ESC) bya UAV bihuza capacitors nyinshi. Iyo batiri ihujwe, izi capacitors zishyushya vuba, bigatuma habaho impedance nto cyane. Ibi bituma umuriro winjira ako kanya urenga cyane uwo muyaga usanzwe, bigatuma umwuka winjira uhinduka bitewe n'uwo muyaga mwinshi hanyuma bigatanga imiyoboro y'amashanyarazi. Imiyoboro gakondo, idafite imiterere myiza yo kurinda, ntishobora kwihanganira umuriro mwinshi usohoka mu gihe gito. Ibi ntibitera gusa ubushyuhe bwinshi no kwiyongera k'ubudahangarwa bw'amashanyarazi ahubwo binatera ibyago byo kwangiza ubushyuhe bwa batiri. Dukurikije imibare y'inganda, impanuka z'umutekano muri UAV ziterwa no gushyushya imiyoboro zitera hejuru ya 25% by'impanuka zose, bigatera igihombo gikomeye ku bakoresha kandi bikabangamira iterambere ryiza ry'inganda za UAV.
II. Iterambere ry'ikoranabuhanga: Uburyo bwo kurinda igice cy'ingenzi cy'ibikoresho birwanya ibyuka
Kugira ngo ikibazo cy’ingufu gikemuke, imashini zirwanya ingufu zashyizeho uburyo busesuye bwo kurinda umutekano binyuze mu guhanga udushya mu ikoranabuhanga:
Ubwa mbere, imiterere yihariye y’imiterere y’aho uhurira. Ikoresha imiterere y’aho uhurira iteye intambwe ya "resistance-first, conduction-late". Iyo connector ihujwe, anti-spark resistor ni yo itangira gukorana. Binyuze mu ihame ryo kugabanya voltage ya resistor, umuvuduko w’intangiriro y’umuvuduko ugabanukaho hejuru ya 60%, bikarinda ko umwuka uhinduka no gukora arc. Iyi miterere y’imiterere igabanya inzira yo gukora arc aho isoko rituruka, igatanga imbogamizi ya mbere y’umutekano wo guhuza circuit.
Icya kabiri, ikoreshwa ry'ibikoresho bigezweho. Ibikoresho bifatanye bifite uburyo bwo gutwikira zahabu bufite ubugari bwa 3μm, butagenzura gusa ubushobozi bwo guhangana n'ibintu biri munsi ya 5mΩ kugira ngo bigabanye ubushyuhe mu gihe cyo kohereza umuriro ariko kandi butanga ubushobozi bwo kurwanya ingese no kwangirika. Ibikoresho bifatanye n'icyuma gikozwe mu cyuma cya aluminiyumu cyo mu rwego rw'indege, bikaba byoroshye (40% byoroheje ugereranyije n'ibikoresho bisanzwe) mu gihe bihangana n'imitingito ikomeye n'isuri ikomeye ku bidukikije, bigatuma igikoresho gihuza ibintu kidahungabana mu gihe cy'akazi katoroshye.
Icya gatatu, guhuza modules za control zikoresheje ubwenge. Module yubatswemo iyoborwa na MCU ituma habaho inzira y’ubushyuhe bw’amasegonda 0.5-2, bigatuma ubushyuhe buzamuka neza buva kuri 0 bujya ku gaciro kagenwe, bikuraho burundu ibyago byo gusohora umuriro mwinshi mu gihe gito. Urugero, TE Connectivity's anti-spark connectors, ikoresheje iri koranabuhanga, yagenzuye amahirwe yo gukora arc iri munsi ya 0.01%, yongera cyane umutekano w’imikorere ya UAV.
III. Ishyirwa mu bikorwa ry'ahantu haberanye: Uburyo butandukanye bwo gukoresha ibyuma birwanya imashini
Uburyo butandukanye bwo gukoresha UAV bushyiraho ibisabwa bitandukanye ku mikorere ku bikoresho birwanya imashini zikoresha amashanyarazi, bigatuma habaho iterambere ry’ibikoresho byihariye:
Mu rwego rwo kurinda ibimera by’ubuhinzi, UAV zigomba gusimbuzwa bateri zazo kenshi (ubusanzwe inshuro 10-20 ku munsi), ibyo bikaba bisaba cyane igihe cyo kuzikoresha no koroshya uburyo bwo kuzikoresha. 200A ya Hobbywing ikoresha igishushanyo mbonera cyihuse cyo kuzikoresha, igihe cyo kuzikoresha kirenga inshuro 5.000 n'uburemere bwa garama 35 gusa, gihuye na sisitemu za bateri za 14S zifite voltage nyinshi. Mu bikorwa bifatika, iyi connector yagabanyije ingaruka za ESC ziterwa n'amashanyarazi mu mashini zirinda ibimera ku kigero cya 92%, binongera cyane imikorere myiza.
Mu bijyanye no gutwara ibintu, UAV zikoresha uburyo bwo gusimbuza bateri "mu buryo bw'iminota mike", zikenera kohereza umuriro mwinshi ndetse no gutanga ubushyuhe buke. Pogo Pin ya Toplink ikoresha igishushanyo mbonera cya shunt ihuza ibintu bitatu. Mu gihe cy'umuriro w'amashanyarazi wa 80A, ubushyuhe buzamuka ni 35K gusa (buri hasi cyane ugereranije n'urugero rw'inganda rwa 60K). Dushingiye kuri iyi kontakt, sitasiyo za UAV za SF Express zishobora kurangiza gusimbuza bateri ya 10kW mu masegonda 45, umubare wa UAV zikorerwa buri munsi urenga 500, zujuje ibisabwa mu gutwara ibintu.
Mu igenzura ry’ibintu bishobora guteza akaga nko mu bibanza bya peteroli na gaze ndetse no mu bibanza bya shimi, ubushobozi bwo kwirinda guturika buba ikintu cy’ingenzi gisabwa. Aka gahuza karwanya guturika gafite imiterere idaturika ka DJI ka M300RTK UAV gafite imiterere idaturika, gafite uburinzi bwa IP68. Gashobora kugumana imbaraga zihamye zo gushyiramo ingufu no gukingira mu kirere mu buryo bukabije kuva kuri -40℃ kugeza kuri 85℃, kandi gafite icyemezo cya ATEX kidaturika, gatuma gakoreshwa mu buryo bwizewe mu bidukikije biteje akaga byo mu cyiciro cya kabiri kandi kagakuraho impanuka ziterwa n’ibishashi.
IV. Ingendo z'ejo hazaza: Iterambere ry'ikoranabuhanga rituma ubukungu bwo mu misozi mito butera imbere
Uko politiki zijyanye n'ubukungu bwo mu misozi miremire igenda ishyirwa mu bikorwa buhoro buhoro, uburyo bwo gukoresha UAV burushaho kuba ingorabahizi, bigatuma habaho ibisabwa byinshi ku ikoranabuhanga rirwanya spark connector:
Ku bijyanye n'imikorere, ubushobozi bwo gutwara umuriro buzagera kuri 300A. Hagati aho, ikoranabuhanga rya nanocoating rizakoreshwa mu kongera ubushobozi bwo kudakora neza, rikongera igihe cyo gukoresha porogaramu kugeza ku nshuro zirenga 200.000 kugira ngo rihuze n'ibisabwa mu bikorwa by'igihe kirekire kandi bikomeye. Mu rwego rw'ubutasi, ibyuma bihuza ibyuma bizahuza ibikoresho bipima ubushyuhe n'ibikoresho bigenzura ubushyuhe kugira ngo bitange ibitekerezo by'igihe nyacyo ku mikorere kandi binatangize uburyo bwo kwirinda umuriro mu gihe habayeho ibintu bidasanzwe. Urugero, ibikoresho bihuza ibyuma birwanya umuriro bya Amphenol bishobora kohereza amakuru kuri sisitemu yo kugenzura indege binyuze muri CAN bus, bigatuma habaho kuburira hakiri kare kandi bigakomeza kunoza imikorere y'umutekano wa UAV.
Byongeye kandi, kunoza SWaP (Ingano, Uburemere, n'Ingufu) byabaye icyerekezo cy'ingenzi cy'iterambere. Gukoresha imashini nshya zikingira ikirere zikoresha thermoplastic hamwe n'uburyo bwo gushushanya inshinge bizagabanya ingano ho 30% n'uburemere ho 25% mu gihe binongera imbaraga z'ibicuruzwa. Imashini nto zirwanya spark zakozwe n'inganda zo mu gihugu, zifite ingano imwe gusa y'ibicuruzwa gakondo, zishobora gukoreshwa ku modoka ntoya zitwara abagenzi, bityo bikongera umwanya wo gutwara ibikoresho.
Nubwo ari ntoya, imiyoboro irwanya imirasire ifite uruhare runini mu kugenzura imikorere myiza ya UAV. Kuva ku kurinda ibihingwa by’ubuhinzi kugeza ku gutwara ibikoresho no kugenzura ibintu bishobora guteza akaga gakomeye, ivugurura ryabyo mu ikoranabuhanga ryagiye rifitanye isano rya hafi n’iterambere ry’inganda zirwanya imirasire. Mu gihe kizaza, hamwe n’ivugurura ry’ikoranabuhanga rihoraho, imiyoboro irwanya imirasire ntizaba "imbogamizi z’umutekano" kuri UAV gusa, ahubwo izaba n’inkingi z’ingenzi mu micungire y’ingufu, birinda iterambere ry’ubukungu bwo mu misozi miremire.
