Poganizira za anthu okalamba komanso kusowa kwa antchito akumidzi, kusintha kwa nzeru zaulimi kwakhala nkhani yapadziko lonse lapansi. Monga ukadaulo wamakono waulimi wogwira ntchito bwino komanso wosinthasintha, kubzala ma drone kukusintha kuchoka pa "kufalitsa kwambiri" kupita ku "kuwombera molondola". Pambuyo pa kusinthaku kwaukadaulo, ma micro stepper motors akuchita gawo lofunika kwambiri - amalola mbewu iliyonse kuyikidwa bwino pamalo ake, zomwe zimapangitsa kuti ulimi ukhale wolondola "wa masentimita".
Nkhaniyi ifotokoza momwe ma micro stepper motors akhala ofunikira kwambiri pakubzala mbewu molondola pogwiritsa ntchito ma drones, poyang'ana kwambiri mbali zitatu: mfundo zaukadaulo, machitidwe owongolera, ndi momwe amagwiritsidwira ntchito.
Mavuto a mafakitale chifukwa cha kubzala ma drone
Njira yachikhalidwe yoberekera mbewu ya drone imagwiritsa ntchito ma centrifugal disc kapena pneumatic seeding, pomwe mbewu zimatayidwa kuchokera mu hopper ndikubalalika ngati fan. Njira yoberekera mbewu iyi ili ndi nkhani zitatu zazikulu:
Kuvuta kupanga mizere ndi mabowo:Njira yobzalira mbewu ndi yovuta kulamulira malo obzalira mbewu, zomwe zimapangitsa kuti zikhale zosatheka kupanga mizere ndi mabowo obzalira nthawi zonse, zomwe zimakhudza kayendetsedwe ka munda ndi mpweya wabwino komanso kulowa kwa kuwala.
Kusokoneza kuchokera kumunda wa mphepo ya rotor:Madzi otuluka kuchokera ku rotor ya drone amatha kufalitsa mbewu, zomwe zimapangitsa kuti mbewu zisafe mofanana, makamaka panthawi yogwira ntchito mwachangu.
Kusafanana bwino kwa mbewu:Kusiyanasiyana kwa kubzala mbewu zachikhalidwe nthawi zambiri kumakhala kwakukulu, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zofunikira za ulimi wamakono kuti mbewu zimere molondola.
Mavuto amenewa amakhudza mwachindunji kuchuluka kwa kumera kwa mbewu komanso zokolola zabwino kwambiri monga mpunga. Momwe mungabzalire mbewu molondola komanso mofanana kwakhala vuto laukadaulo lomwe likufunika kuthetsedwa mwachangu pakugwiritsa ntchito ma drone muulimi.
Ntchito yaikulu ya mota ya micro stepper: "switch" yobzala mbewu molondola
Kuti tithetse mavuto omwe atchulidwa pamwambapa, chinsinsi chili pakusintha kuchoka pa "kufalitsa" kupita ku "kubzala molunjika" - komwe mbewu iliyonse imayikidwa bwino kudzera mu chipangizo chamakina. Munjira iyi, mota ya micro stepper imagwira ntchito ngati chowongolera chachikulu chowongolera chipangizo choyezera mbewu.
Chigawo chachikulu cha chipangizo choyesera mbewu ndi chipangizo choyezera mbewu, chomwe chimayang'anira kutulutsa ndi kutulutsa mbewu kuchokera m'bokosi la zinthu. Liwiro lozungulira la chipangizo choyezera mbewu limatsimikizira mwachindunji kuchuluka ndi liwiro la mbewu.
Mota ya micro stepper imagwira ntchito yofunika kwambiri pankhaniyi. Mota ya stepper imasonyeza khalidwe la "kuzungulira ngodya yokhazikika pa chizindikiro chilichonse cha pulse", ndipo liwiro lake lozungulira limagwirizana kwambiri ndi ma frequency a pulse. Dongosolo lowongolera limagwiritsa ntchito njira ya PID kuti liziwongolera liwiro lozungulira la mota ya stepper, kusintha liwiro la chipangizo choyezera mbewu nthawi yeniyeni kuti zitsimikizire kufanana kolondola pakati pa kuchuluka kwa mbewu ndi liwiro la ndege ya drone.
Deta yoyesera ikusonyeza kuti makina oberekera a drone, omwe amayendetsedwa ndi mota yoyendera, ali ndi mphamvu zabwino kwambiri zosinthira mphamvu, ndipo cholakwika chapakati pa kuchuluka kwa mbewu ndi chochepera 4% pa liwiro logwira ntchito kuyambira 1.0 mpaka 2.5 m/s.
Kuwonjezera pa kuwongolera liwiro lozungulira, ma micro stepper motors amathanso kuyendetsa kusuntha ndi kusintha kwa ngodya ya payipi yobzala. Ukadaulo wa patent ukuwonetsa kuti drone yokhala ndi ntchito yobzala imakhala ndi stepper motor yokhazikika pakhoma lamkati la thupi, ndipo kumapeto kwa injiniyo kumalumikizidwa ndi ndodo yolumikizidwa, yomwe imayendetsa payipi yobzala kuti iyende mmwamba ndi pansi kudzera mu chipika cholumikizidwa, zomwe zimapangitsa kuti kapangidwe ka mbewu katsegulidwe bwino.
Kapangidwe kameneka kamagwiritsa ntchito kasupe wobwezeretsanso ndi kapangidwe ka mbale yotetezera. Pamene mota yoyendetsa imayendetsa kapangidwe ka mbewu kuti isunthe pansi, mbale yotetezera imachoka nthawi yomweyo, kutsegula dzenje lotulutsira, zomwe zimathandiza kuti mbewu zigwere pamalo omwe zakonzedweratu. Kubzala ndi kutulutsa mbewu kumayendetsedwa mofanana ndi kapangidwe ka mphamvu imodzi, kuonetsetsa kuti palibe kusiyana pakati pa zochita zobzala ndi kutulutsa mbewu, zomwe zimapangitsa kuti ntchito ikhale yabwino komanso ubwino wa mbewu.
Mu nkhani yobzala usiku, ma micro stepper motors nawonso amachita gawo lapadera. Patent ya drone youluka yotsika kwambiri yaulimi yobzala ikuwonetsa kapangidwe kameneka: mota ya stepper imayendetsa kuwala kuti kuzungulire kumbuyo ndi mtsogolo pang'ono, kusintha momwe kuwala kumayatsira, pomwe nthawi yomweyo imayendetsa chubu chobzala kuti chizungulire kudzera mu ndodo yolumikizira, kuonetsetsa kuti kuwala ndi chubu chobzala zikuyang'ana dzenje lobzala molumikizana.
Kamera ikazindikira dzenje lobzala, injini yoyendera imasintha bwino ma angles a kuwala ndi chubu choberekera mbeu kuti ipange mbeu yolondola "yolunjika mpaka pa mfundo", zomwe zimathandiza kuti mbewu zisapatuke kuchoka m'dzenje lobzala nthawi yausiku. Izi zimapereka chithandizo chaukadaulo pa ntchito yoberekera mbewu yosalekeza ya maola 24.
Dongosolo lowongolera bwino mbewu za drone limafuna mgwirizano wogwirizana wa zida ndi mapulogalamu. Potengera "dongosolo lowongolera chipangizo chowongolera mpunga cha drone point-shooting" lomwe linapangidwa ndi gulu la South China Agricultural University mwachitsanzo, dongosololi limakwaniritsa ntchito zotsatirazi:
Kulamulira kwa PID closed-loop:Kutengera ndi njira ya PID, liwiro lozungulira la mota yoyendera ya chipangizo choyezera mbewu limayendetsedwa mozungulira. Kuchuluka kwa kuyeza mbewu kumasinthidwa nthawi yeniyeni malinga ndi liwiro la ndege ya drone, kuonetsetsa kuti mbeu zimamera nthawi zonse pagawo lililonse.
Kulamulira kubzala mbewu kwa makina a boma:Pulogalamu yowongolera kubzala mbewu imapangidwa kudzera mu makina okhazikika kuti ikwaniritse njira zonse zowongolera zokha, kuphatikiza kukonzekera njira yogwirira ntchito, kuwerengera kuchuluka kwa kubzala mbewu, kukhazikitsa magawo, kuwonetsa kuchuluka kwa mbewu, ndi kubzala mbewu zokha.
Kugwirizana kwa siteshoni yapansi panthaka:Pangani ntchito zowonjezera za siteshoni yapansi, zomwe zimathandiza ogwira ntchito kukonzekera njira zoyendera ndege, kukhazikitsa magawo, ndikuyang'anira momwe ntchito ikuyendera pa kompyuta, ndikukwaniritsa ntchito zanzeru pogwiritsa ntchito "kubzala kamodzi kokha".
Mayeso a m'munda atsimikizira magwiridwe antchito abwino kwambiri a dongosololi: pansi pa kutalika kwa ntchito kwa mamita 1.5, kuchuluka kwa mbewu kwa 90 mpaka 150 kg/hm², ndi liwiro logwira ntchito la 0.5 mpaka 2.0 m/s, kuchuluka kwa kusiyana kwa mbewu kumayambira pa 20.51% mpaka 35.52%. Zolakwika zokhudzana ndi kuchuluka kwa mbewu m'munda ndi 2.47% ndi 4.12%, motsatana, ndipo kuchuluka kwa kuwonongeka kwa mbewu ndi 0.34% ndi 0.18% yokha, zomwe zikukwaniritsa zofunikira zowongolera molondola pakubzala mpunga mumlengalenga monga momwe zanenedwera ndi miyezo yoyenera.
Chifukwa cha kukhwima kosalekeza kwa ukadaulo, njira zoberekera mbewu molondola pogwiritsa ntchito ma micro-stepping motors zikusuntha kuchokera ku labotale kupita ku minda. Kufunika kwawo kwa malonda kumawonekera m'mbali zotsatirazi:
Kusunga mbewu:Kufesa molondola kumapewa kutaya zinthu monga kufesa kwachikhalidwe, kuchepetsa kuchuluka kwa mbewu pa ekala ndi 10% mpaka 20%.
Kuthekera kochulukitsa zokolola:Njira yobzala mizere ndi mabowo imawongolera mpweya wabwino komanso kufalikira kwa kuwala kwa mbewu, zomwe zimathandiza polima ndi kudzaza tirigu kumapeto. Akuyembekezeka kuwonjezera zokolola ndi 5% mpaka 10%.
Kulowa m'malo mwa ntchito:Drone yobzala mbewu yeniyeni imatha kugwira ntchito zoposa maekala mazana ambiri patsiku, zomwe zimalowa m'malo mwa ntchito yobzala ndi kubzala mbewu pamanja.
Mawindo owonjezera ogwirira ntchito: Mothandizidwa ndi makina owunikira usiku oyendetsedwa ndi injini yaing'ono komanso yoyang'anira malo, ma drone amatha kugwira ntchito mosalekeza usiku, zomwe zimapangitsa kuti nyengo yabwino kwambiri yaulimi ikhale yabwino kwambiri.
Poganizira zamtsogolo, kugwiritsa ntchito ma micro stepper motors m'munda wobzala mbewu molondola pa ma drones kudzawonetsa njira zitatu zazikulu:
Kuchepetsa ndi kuphatikiza kwina: Pamene kukula kwa injini kukuchepa kufika pansi pa 8mm, chipangizo choberekera mbewu chidzakhala chopapatiza kwambiri, zomwe zimathandiza kuti mbewu zambiri zinyamulidwe ndikuwonjezera nthawi yogwira ntchito imodzi.
Luntha Lowonjezereka: Mwa kuphatikiza masomphenya a makina ndi ma algorithms a AI, makina obzala mbewu omwe amayendetsedwa ndi mota yoyendera amatha kusintha okha kuya kwa mbewu ndi mtunda wa mizere kutengera momwe nthaka ilili ndi chinyezi komanso kusintha kwa malo, zomwe zimapangitsa kuti "zigwirizane ndi momwe zinthu zilili m'deralo".
Kubzala mbewu zambiri: Ukadaulo wamakono umagwiritsidwa ntchito makamaka pa mbewu zakumunda monga mpunga, ndipo udzafalikira ku mbewu zamalonda monga chimanga, soya, ndi ndiwo zamasamba mtsogolo, kukwaniritsa zosowa za kubzala mbewu zosiyanasiyana.
Mapeto
Kuyambira kufesa kwambiri mpaka kuwombera bwino malo, ma micro stepper motors akuyendetsa kusintha kwakukulu mu ukadaulo wobzala mbewu za drone. Ndi kuwongolera molondola kwa micrometer, amatsimikizira kuti mbewu iliyonse imapeza "kwawo" - iyi ndi tanthauzo lenileni la "osati tsitsi lochepa".
Pamene nthawi ya ulimi wolondola yayamba, kufunika kwa ma micro stepper motors kudzasinthidwa: sikuti ndi "zigawo zokhazikika" zokha m'munda wa automation yamafakitale, komanso "magiya ofunikira" pakusintha kwanzeru kwa ulimi wamakono. M'tsogolomu, tili ndi chifukwa chokhulupirira kuti ukadaulo uwu, wochokera kumakampani, udzawala kwambiri m'minda yayikulu.
