Ngenxa yokuguga kwabantu kanye nokuntuleka kwabasebenzi basemakhaya, ukuguqukela ekuhlakanipheni kwezolimo sekuyinkinga yomhlaba wonke. Njengobuchwepheshe besimanje bezolimo obusebenza kahle futhi obuguquguqukayo, ukuhlwanyela ama-drone kuguqukela ekubeni “ukusakaza kabanzi” kuye “ekudubuleni amaphuzu ngendlela eqondile”. Ngemuva kwalokhu kugxuma kobuchwepheshe, ama-micro stepper motors adlala indima ebalulekile – enza ukuba imbewu ngayinye ibekwe kahle endaweni yayo ekhethiwe, kufezwe ngempela ezolimo ezinembile “ezinembe ngamasentimitha”.
Lesi sihloko sizohlola ukuthi ama-micro stepper motors abe kanjani amandla ayinhloko okushayela imbewu eqondile ngama-drones, sigxile ezicini ezintathu: izimiso zobuchwepheshe, izinhlelo zokulawula, kanye namacala okusetshenziswa.
Izindawo ezibuhlungu embonini zokutshala ama-drone
Indlela yendabuko yokuhlwanyela imbewu ye-drone isebenzisa kakhulu i-centrifugal disc noma i-pneumatic seeding, lapho imbewu iphonswa khona isuka e-hopper bese ihlakazeka ngendlela efana ne-fan. Le ndlela yokuhlwanyela imbewu iveza izinkinga ezintathu ezivelele:
Ubunzima bokwakha imigqa nemigodi:Indlela yokuhlwanyela inzima ukulawula indawo yokufika kwembewu, okwenza kube nzima ukwakha imigqa nemigodi yokuhlwanyela evamile, okuthinta ukuphathwa kwensimu okulandelayo kanye nokungena komoya kanye nokungena kokukhanya.
Ukuphazamiseka okuvela ensimini yomoya we-rotor:Ukuhlanzwa kwamanzi okubangelwa yi-rotor ye-drone kungasakaza imbewu, okuholela ekuhlwanyeleni okungalingani, ikakhulukazi ngesikhathi sokusebenza ngesivinini esikhulu.
Ukungalingani kahle kokuhlwanyela imbewu:Ukwehlukahlukana kokuhlwanyela kwendabuko kuvame ukuba phezulu, okwenza kube nzima ukuhlangabezana nezidingo zezolimo zanamuhla ukuze kutholakale ukunemba kokuhlwanyela.
Lezi zinkinga zithinta ngqo izinga lokuvela kwezithombo kanye nesivuno sokugcina sezitshalo ezifana nelayisi. Indlela yokufeza ukuhlwanyela okunembile nokufanayo sekuyinkinga yobuchwepheshe okudingeka ixazululwe ngokushesha ekusetshenzisweni kwama-drone kwezolimo.
Umsebenzi oyinhloko wenjini ye-micro stepper: "iswishi" yokutshala imbewu ngendlela enembile
Ukuze kuxazululwe izinkinga ezishiwo ngenhla, isihluthulelo sisekushintsheni kusukela “ekusakazweni” kuya “ekuhlwanyeleni okuqondile” – lapho imbewu ngayinye ibekwa khona ngokunembile ngedivayisi yomshini. Kule ndlela, i-micro stepper motor isebenza njenge-actuator eyinhloko yokulawula idivayisi yokulinganisa imbewu.
Ingxenye eyinhloko yedivayisi yokuhlwanyela imbewu yokunquma iphuzu yidivayisi yokulinganisa imbewu, enesibopho sokukhipha nokukhipha imbewu ngobuningi ebhokisini lezinto ezibonakalayo. Ijubane lokujikeleza ledivayisi yokulinganisa imbewu linquma ngqo inani kanye nesivinini sokuhlwanyela imbewu.
Injini encane ye-stepper idlala indima ebalulekile kule nqubo. Injini ye-stepper ikhombisa isici "sokujikeleza i-engeli eqondile yokufaka isignali ngayinye ye-pulse", futhi isivinini sayo sokujikeleza silingana ngokuqinile nemvamisa ye-pulse. Uhlelo lokulawula lusebenzisa i-algorithm ye-PID ukwenza ukulawula okuvaliwe kwejubane lokujikeleza kwenjini ye-stepper, ukulungisa ijubane lokusebenza kwedivayisi yokulinganisa imbewu ngesikhathi sangempela ukuqinisekisa ukufana okunembile phakathi kwenani lokutshala kanye nesivinini sokundiza se-drone.
Idatha yokuhlola ikhombisa ukuthi uhlelo lokuhlwanyela imbewu lwe-drone, olulawulwa yi-stepper motor, lubonisa amakhono amahle kakhulu okulungisa aguquguqukayo, ngephutha elilinganiselwe elilinganiselwe lenani lokuhlwanyela imbewu elingaphansi kuka-4% ngesivinini sokusebenza esisukela ku-1.0 kuya ku-2.5 m/s.
Ngaphezu kokulawula ijubane lokujikeleza, ama-motor amancane e-stepper angaphinde ashayele ukufuduka kanye nokulungiswa kwe-engeli yepayipi lokutshala imbewu. Ubuchwepheshe be-patent bubonisa ukuthi i-drone enomsebenzi wokutshala imbewu ine-stepper motor eboshwe odongeni lwangaphakathi lomzimba, futhi ukuphela kokuphuma kwenjini kuxhunywe entongeni enentambo, eshayela ipayipi lokutshala imbewu ukuthi lihambe phezulu naphansi ngebhulokhi enentambo, kufezwe ukuvulwa nokuvalwa okunembile kwesakhiwo sokutshala imbewu.
Lo mklamo usebenzisa isiphethu sokusetha kabusha kanye nesakhiwo sepuleti lokuvikela. Lapho injini ye-stepper iqhuba isakhiwo sokutshala ukuze siye phansi, ipuleti lokuvikela lihamba ngasikhathi sinye, livule imbobo yokukhipha, livumela imbewu ukuthi iwele endaweni efanele. Ukutshala nokukhipha kulawulwa ngokulinganayo yisakhiwo samandla esisodwa, okuqinisekisa ukuthi akukho sikhala phakathi kwezenzo zokutshala nokukhipha, okuthuthukisa kakhulu ukusebenza kahle komsebenzi kanye nekhwalithi yokutshala.
Esimweni sokuhlwanyela ebusuku, ama-micro stepper motors nawo adlala indima eyingqayizivele. Ilungelo lobunikazi le-drone yezolimo endizayo endaweni ephansi yokuhlwanyela lembula umklamo onjalo: i-stepper motor iqhuba ukukhanya ukuze kujikeleze emuva naphambili nge-amplitude encane, ilungisa indlela yokukhanya komthombo wokukhanya, ngenkathi ngesikhathi esifanayo iqhuba i-sowing tube ukuze ijikeleze ngenduku yokuxhuma, iqinisekisa ukuthi ukukhanya kanye ne-sowing tube kuqondiswe emgodini wokutshala ngokuvumelana.
Uma ikhamera ibona umgodi wokutshala, injini ye-stepper ilungisa ngokunembile ama-engeli e-spotlight kanye ne-seeding tube ukuze kufezwe ukuhlwanyela okunembile “okuqondile”, okuvimbela ngempumelelo imbewu ukuthi ingaphambuki emgodini wokutshala ngesikhathi sokusebenza ebusuku. Lokhu kunikeza ukwesekwa kobuchwepheshe kwemisebenzi yokuhlwanyela engaphazanyiswa yamahora angama-24.
Uhlelo oluphelele lokulawula ukuhlwanyela imbewu ngokunemba kwe-drone ludinga ukubambisana ngokubambisana kwehadiwe kanye nesofthiwe. Uma sibheka "uhlelo lokulawula idivayisi yokuhlwanyela irayisi ye-drone point-shooting" oluklanywe yithimba laseSouth China Agricultural University njengesibonelo, lolu hlelo lufeza imisebenzi elandelayo:
Ukulawula i-PID closed-loop:Ngokusekelwe ku-algorithm ye-PID, isivinini sokujikeleza semoto ye-stepper yedivayisi yokulinganisa imbewu silawulwa ngendlela evaliwe. Izinga lokulinganisa imbewu lilungiswa ngesikhathi sangempela ngokuya ngesivinini sokundiza se-drone, okuqinisekisa inani eliqhubekayo lokutshala imbewu endaweni ngayinye.
Ukulawulwa kokuhlwanyela imbewu komshini wesifundazwe:Uhlelo lokulawula ukuhlwanyela imbewu luklanywe ngomshini wesimo esilinganiselwe ukuze kufezwe ukulawulwa kokuzenzakalela kwenqubo ephelele, okuhlanganisa ukuhlela umzila wokusebenza, ukulinganiswa kwesilinganiso sokuhlwanyela imbewu, ukusethwa kwamapharamitha, ukuboniswa kwensalela yembewu, kanye nokuhlwanyela imbewu okuzenzakalelayo.
Ukuhlanganiswa kwesiteshi saphansi:Thuthukisa imisebenzi yesiteshi esingaphansi komhlaba ehambisanayo, okuvumela opharetha ukuhlela izindlela zendiza, ukusetha amapharamitha, nokuqapha isimo sokusebenza ku-terminal yekhompyutha, ukufeza imisebenzi ehlakaniphile "ngokutshala okukodwa".
Ukuhlolwa kwensimu kuqinisekisile ukusebenza okuhle kakhulu kwalesi simiso: ngaphansi kwezimo zokuphakama kokusebenza okungamamitha ayi-1.5, izinga lokuhlwanyela elingama-90 kuya ku-150 kg/hm², kanye nesivinini sokusebenza esingu-0.5 kuya ku-2.0 m/s, i-coefficient of variance for seniformity seeding isukela ku-20.51% kuya ku-35.52%. Amaphutha ahlobene emazingeni okuhlwanyela kwensimu angama-2.47% kanye no-4.12%, ngokulandelana, kanti amazinga okulimala kwembewu angama-0.34% kanye no-0.18% kuphela, ahlangabezana ngokugcwele nezidingo zokulawula ngokunemba kokuhlwanyela irayisi emoyeni njengoba kushiwo yizindinganiso ezifanele.
Njengoba ubuchwepheshe buqhubeka nokuvuthwa, izinhlelo zokuhlwanyela imbewu ngokunemba ezisekelwe kuma-motor amancane ziyasuka elabhorethri ziye emasimini. Inani lazo lezentengiselwano libonakala kulezi zici ezilandelayo:
Ukulondolozwa kwembewu:Ukuhlwanyela ngokunembile kugwema isenzakalo sokuchitha imali sokuhlwanyela okusakazwayo kwendabuko, kunciphisa inani lembewu ngehektare ngalinye ngo-10% kuya ku-20%.
Amandla okwandisa isivuno:Indlela yokutshala yokwakha imigqa nemigodi ithuthukisa izimo zokungenisa umoya kanye nokudlulisa ukukhanya kwezitshalo, okuzuzisayo ekulimeni nasekugcwaliseni okusanhlamvu esigabeni esilandelayo. Kulindeleke ukuthi ikhulise isivuno ngo-5% kuya ku-10%.
Ukushintshaniswa kwabasebenzi:I-drone eqondile yokutshala imbewu ingaqeda imisebenzi engaphezu kwamahektha angamakhulu ngosuku, ithathe indawo enkulu yokufakelwa kwezitshalo ngesandla kanye nomsebenzi wokuhlwanyela.
Ifasitela lokusebenza elandisiwe: Ngosizo lohlelo lokukhanyisa ebusuku oluqhutshwa yi-micro stepper motor kanye nohlelo lokubeka, ama-drone angasebenza njalo ebusuku, athathe isizini engcono kakhulu yokulima.
Uma sibheka phambili, ukusetshenziswa kwama-micro stepper motors emkhakheni wokuhlwanyela imbewu ngokunemba kwama-drones kuzobonisa izitayela ezintathu ezinkulu:
Ukwenziwa kube kuncane kakhulu kanye nokuhlanganiswa: Njengoba ububanzi benjini buncipha bube ngaphansi kuka-8mm, idivayisi yokutshala izoba ncane kakhulu, okuvumela ukuthuthwa kwembewu eningi futhi kwandise isikhathi sokusebenza okukodwa.
Ubuhlakani Obuthuthukisiwe: Ngokuhlanganisa ama-algorithms ombono womshini kanye ne-AI, uhlelo lokuhlwanyela imbewu olulawulwa yi-stepper motor lungalungisa ngokuzenzakalelayo ukujula kokuhlwanyela imbewu kanye nesikhala semigqa ngokusekelwe ezimweni zomswakama wenhlabathi kanye nokwehluka kwendawo, kufezwe "ukuzivumelanisa nezimo zendawo" zangempela.
Ukumbozwa kwezitshalo eziningi: Ubuchwepheshe bamanje busetshenziswa kakhulu ezitshalweni zasensimini ezifana nelayisi, futhi buzokhula bufinyelele ezitshalweni zezentengiselwano njengommbila, ubhontshisi, nemifino esikhathini esizayo, kuhlangatshezwane nezidingo zokutshala okuhlukahlukene.
Isiphetho
Kusukela ekuhlwanyeleni okubanzi kuya ekudubuleni okuqondile, ama-micro stepper motors aqhuba ushintsho olukhulu kubuchwepheshe bokuhlwanyela ama-drone. Ngokulawulwa kokunemba kwezinga le-micrometer, aqinisekisa ukuthi imbewu ngayinye ithola "ikhaya" layo - lena incazelo yangempela yokuthi "hhayi unwele olulodwa".
Ngokufika kwenkathi yezolimo ezinembile, inani lama-micro stepper motors lizochazwa kabusha: akuzona nje "izingxenye ezijwayelekile" emkhakheni we-automation yezimboni, kodwa futhi "amagiya ayisihluthulelo" ekuguqulweni okuhlakaniphile kwezolimo zanamuhla. Esikhathini esizayo, sinesizathu sokukholelwa ukuthi lobu buchwepheshe, obuvela embonini, buzokhanya nakakhulu emasimini amakhulu.
