本發明涉及植保(bao)(bao)無人(ren)機噴(pen)施(shi)(shi)技術,具(ju)體涉及一種可實時切換噴(pen)頭的植保(bao)(bao)無人(ren)機噴(pen)施(shi)(shi)系統及方法(fa)。
背景技術:
1、果園(yuan)(yuan)傳統的(de)(de)(de)生產管理大多采(cai)用人(ren)工作業方式(shi)來(lai)完(wan)成(cheng)(cheng),這種方式(shi)不僅作業效率低下,勞動力使用量大,而且人(ren)工作業粗放(fang),不能(neng)及(ji)時應對突(tu)發的(de)(de)(de)狀(zhuang)況,造成(cheng)(cheng)了經濟損失(shi)。果園(yuan)(yuan)植保是生產管理中關鍵的(de)(de)(de)環(huan)節,每年因病(bing)蟲(chong)害造成(cheng)(cheng)的(de)(de)(de)損失(shi)占總產量的(de)(de)(de)25%以(yi)上(shang)。近年來(lai),引(yin)進先進的(de)(de)(de)技術,研(yan)發了多種地(di)走式(shi)噴(pen)霧機(ji),防治效果顯著提升,然而,由于我(wo)國果園(yuan)(yuan)種植模(mo)式(shi)不統一,地(di)走式(shi)噴(pen)霧機(ji)只能(neng)適(shi)用于單一的(de)(de)(de)種植模(mo)式(shi),在(zai)實際(ji)推廣(guang)作業中存在(zai)著較(jiao)大的(de)(de)(de)局限性。無(wu)人(ren)機(ji)上(shang)搭(da)載噴(pen)灑系統從果樹(shu)的(de)(de)(de)上(shang)方進行噴(pen)施,不受(shou)果樹(shu)種植地(di)勢的(de)(de)(de)影響。
2、目前,植保無人(ren)機在(zai)(zai)進(jin)行果樹(shu)噴(pen)灑作業(ye)時(shi)多采(cai)用在(zai)(zai)大(da)田上的(de)噴(pen)灑系統和噴(pen)施模式(shi),但是果樹(shu)樹(shu)體生長(chang)(chang)的(de)特點與(yu)大(da)田糧食(shi)作物差距顯著,果樹(shu)枝(zhi)葉(xie)繁(fan)茂,大(da)田的(de)無人(ren)機噴(pen)施系統采(cai)用直桿式(shi)的(de)噴(pen)施方法在(zai)(zai)應用于果樹(shu)時(shi),很難將農藥均勻噴(pen)施在(zai)(zai)枝(zhi)葉(xie)上。并且(qie)果園多種(zhong)植在(zai)(zai)山地丘陵,種(zhong)植密度因地勢原因多變,果樹(shu)因受外界影(ying)響(xiang)生長(chang)(chang)狀態(tai)不(bu)(bu)同,因此果園果樹(shu)枝(zhi)葉(xie)疏(shu)密不(bu)(bu)一(yi)。
3、相關研究表明,固定大(da)(da)小(xiao)的(de)(de)(de)噴(pen)頭(tou)在(zai)(zai)水(shui)泵的(de)(de)(de)量(liang)(liang)程(cheng)范圍內(nei)霧(wu)化(hua)(hua)后(hou)的(de)(de)(de)霧(wu)滴粒徑變化(hua)(hua)范圍有(you)限(xian),因此需要針對(dui)不(bu)同的(de)(de)(de)應用場景選(xuan)用不(bu)同尺寸的(de)(de)(de)噴(pen)頭(tou),才能獲得比較好的(de)(de)(de)噴(pen)施(shi)效(xiao)果(guo)。然而(er)在(zai)(zai)現有(you)技術(shu)中,在(zai)(zai)執行噴(pen)施(shi)作(zuo)(zuo)業之(zhi)前,會(hui)(hui)事先(xian)選(xuan)擇對(dui)應的(de)(de)(de)噴(pen)頭(tou),而(er)在(zai)(zai)噴(pen)施(shi)作(zuo)(zuo)業過(guo)程(cheng)中,則(ze)一直由該噴(pen)頭(tou)進行噴(pen)霧(wu),碰到不(bu)同繁茂(mao)程(cheng)度的(de)(de)(de)果(guo)樹時,若繼續噴(pen)施(shi),則(ze)會(hui)(hui)導致該果(guo)樹的(de)(de)(de)施(shi)藥不(bu)足(zu)或者施(shi)藥過(guo)量(liang)(liang),影響果(guo)樹的(de)(de)(de)生長(chang)或者浪費農藥;若返航更(geng)換噴(pen)頭(tou),則(ze)會(hui)(hui)額(e)外花費大(da)(da)量(liang)(liang)時間,降低(di)工作(zuo)(zuo)效(xiao)率。
