Ngenxa yokwaluphala kwabantu kunye nokunqongophala kwabasebenzi basemaphandleni, utshintsho oluya kubukrelekrele bezolimo lube yingxaki yehlabathi. Njengeteknoloji yezolimo yanamhlanje esebenzayo neguquguqukayo, ukutyala iidrone kuyatshintsha ukusuka "ekusasazeni ngokubanzi" ukuya "ekudubuleni ngokuchanekileyo". Emva kolu tshintsho lwetekhnoloji, ii-micro stepper motors zidlala indima ebalulekileyo - zenza ukuba imbewu nganye ibekwe ngokuchanekileyo kwindawo yayo emiselweyo, zifezekise ngokwenene ulimo oluchanekileyo "oluchanekileyo ngeesentimitha".
Eli nqaku liza kujonga indlela ii-micro stepper motors eziye zaba ngamandla aphambili okuqhuba imbewu ngokuchanekileyo ngeedrone, zigxile kwiinkalo ezintathu: imigaqo yobugcisa, iinkqubo zolawulo, kunye namatyala okusetyenziswa.
Iindawo ezibangela intlungu kushishino lokulima imbewu yeedrone
Indlela yendabuko yokukhulisa imbewu yedrone isebenzisa ikakhulu idiski ye-centrifugal okanye i-pneumatic seeding, apho imbewu iphoswa ngaphandle kwi-hopper ize isasazeke ngendlela efana neyefeni. Le ndlela yokukhulisa imbewu inemiba emithathu ebalulekileyo:
Ubunzima bokwenza imigca kunye nemingxuma:Indlela yokuhlwayela inzima ukulawula indawo yokufika kwembewu, nto leyo eyenza kube nzima ukwenza imiqolo kunye nemingxunya yokuhlwayela rhoqo, nto leyo echaphazela ulawulo lwentsimi kunye nomoya ophumayo kunye nokungena kokukhanya.

Le micimbi ichaphazela ngokuthe ngqo izinga lokuhluma kwezithole kunye nesivuno sokugqibela sezityalo ezifana nerayisi. Indlela yokufikelela ekuhlwayeleni ngokuchanekileyo nangokulinganayo ibe ngumceli mngeni wobuchwephesha ekufuneka uqwalaselwe ngokukhawuleza ekusebenziseni iidrone kwezolimo.
Umsebenzi oyintloko we-micro stepper motor: "iswitshi" yokutyala imbewu ngokuchanekileyo
Ukujongana nemiba ekhankanyiweyo apha ngasentla, eyona nto iphambili kukutshintsha ukusuka “ekusasazeni” ukuya “ekuhlwayeleni imbewu etsolo” – apho imbewu nganye ibekwa ngokuchanekileyo ngesixhobo soomatshini. Kule ndlela, i-micro stepper motor isebenza njengesixhobo esiphambili sokulawula isixhobo sokulinganisa imbewu.
Eyona nto iphambili kwisixhobo sokulinganisa imbewu sisixhobo sokulinganisa imbewu, esinoxanduva lokukhupha nokukhupha imbewu ngokwenani kwibhokisi yezinto ezibonakalayo. Isantya sokujikeleza kwesixhobo sokulinganisa imbewu simisela ngokuthe ngqo ubungakanani kunye nesantya sokuvelisa imbewu.
I-micro stepper motor idlala indima ebalulekileyo kule nkqubo. I-stepper motor ibonisa uphawu "lokujikeleza i-engile emiselweyo kwi-input nganye yesignali ye-pulse", kwaye isantya sayo sokujikeleza sihambelana ngokungqongqo ne-pulse frequency. Inkqubo yolawulo isebenzisa i-algorithm ye-PID ukwenza ulawulo oluvaliweyo kwisantya sokujikeleza se-stepper motor, ilungisa isantya sokusebenza kwesixhobo sokulinganisa imbewu ngexesha langempela ukuqinisekisa ukufana okuchanekileyo phakathi kobungakanani bokuhlwayela imbewu kunye nesantya sokubhabha se-drone.
Idatha yovavanyo ibonisa ukuba inkqubo yokuhlwayela imbewu yedrone, elawulwa yimoto ye-stepper, ibonisa amandla okulungisa aguquguqukayo agqwesileyo, kunye nempazamo ephakathi yobungakanani bokuhlwayela imbewu engaphantsi kwe-4% kwisantya sokusebenza esiqala kwi-1.0 ukuya kwi-2.5 m/s.
Ukongeza ekulawuleni isantya sokujikeleza, ii-micro stepper motors zinokuqhuba ukufuduka kunye nokulungiswa kwe-engile yombhobho wokutyala imbewu. Itekhnoloji yelungelo lomenzi ibonisa ukuba i-drone enomsebenzi wokutyala imbewu ine-stepper motor enamathele eludongeni lwangaphakathi lomzimba, kwaye isiphelo semveliso yemoto siqhagamshelwe kwintonga enemisonto, eqhuba umbhobho wokutyala imbewu ukuba uhambe uye phezulu nasezantsi ngebhloko enemisonto, nto leyo efezekisa ukuvulwa nokuvalwa ngokuchanekileyo kwesakhiwo sokutyala imbewu.
Olu yilo lusebenzisa intwasahlobo yokuseta kwakhona kunye nesakhiwo sepleyiti yokukhusela. Xa i-stepper motor iqhuba isakhiwo sokutyala imbewu ukuba siye ezantsi, ipleyiti yokukhusela iyahamba ngaxeshanye, ivula umngxuma wokukhupha imbewu, ivumela imbewu ukuba iwele ngokuchanekileyo kwindawo emiselweyo. Ukukhupha imbewu kunye nokukhupha imbewu kulawulwa ngokulinganayo sisakhiwo esinye samandla, kuqinisekisa ukuba akukho msantsa phakathi kwezenzo zokutyala imbewu kunye nokukhupha, nto leyo ephucula kakhulu ukusebenza kakuhle kunye nomgangatho wokutyala imbewu.
Kwimeko yokuhlwayela ebusuku, ii-micro stepper motors nazo zidlala indima ekhethekileyo. Ilungelo elilodwa lomenzi we-drone yezolimo ebhabhayo ekwindawo ephantsi yokulima yokuhlwayela lityhila uyilo olunjalo: i-stepper motor iqhuba i-spotlight ukuba ijikeleze ibuyele umva nge-amplitude encinci, ilungisa indlela yokukhanya komthombo wokukhanya, ngelixa ngaxeshanye iqhuba i-sowing tube ukuba ijikeleze ngentonga yokudibanisa, iqinisekisa ukuba i-spotlight kunye ne-sowing tube zijoliswe kwindawo yokutyala ngokulandelelana.
Xa ikhamera ibona umngxuma wokutyala, i-stepper motor ilungisa ngokuchanekileyo ii-engile ze-spotlight kunye ne-seeding tube ukuze kufezekiswe ukuhlwayela ngokuchanekileyo "kwi-point-to-point", nto leyo ethintela ngempumelelo imbewu ekubeni iphambuke kumngxuma wokutyala ngexesha lokusebenza ebusuku. Oku kubonelela ngenkxaso yobugcisa kwimisebenzi yokuhlwayela engaphazanyiswayo yeeyure ezingama-24.
