沈陽自動(dòng)化所：智能控制技術(shù)助力甘蔗收割

2022-09-16 09:22:45 來源：中國(guó)科學(xué)院沈陽自動(dòng)化研究所 閱讀量：16042 評(píng)論

導(dǎo)讀：近日，中國(guó)科學(xué)院沈陽自動(dòng)化研究所牽頭的中科院STS項(xiàng)目“甘蔗收獲機(jī)械智能化技術(shù)研究與裝備研發(fā)”通過驗(yàn)收。

　　【農(nóng)機(jī)網(wǎng) 科技創(chuàng)新】甘蔗收獲環(huán)節(jié)是制約甘蔗種植實(shí)現(xiàn)全程機(jī)械化的短板。我國(guó)目前國(guó)內(nèi)甘蔗收獲機(jī)系統(tǒng)與國(guó)外先進(jìn)機(jī)型相比還有很大差距，且國(guó)外先進(jìn)機(jī)型價(jià)格昂貴、維修服務(wù)難，難以大量推廣應(yīng)用，迫切需要研發(fā)新型甘蔗收獲機(jī)，提高機(jī)械的智能化技術(shù)水平。
 
　　近日，中國(guó)科學(xué)院沈陽自動(dòng)化研究所牽頭的中科院STS項(xiàng)目“甘蔗收獲機(jī)械智能化技術(shù)研究與裝備研發(fā)”通過驗(yàn)收。研究所聯(lián)合合作單位研發(fā)了甘蔗收獲機(jī)與田間轉(zhuǎn)運(yùn)車協(xié)同作業(yè)系統(tǒng)、自主作業(yè)系統(tǒng)，以及切段式智能甘蔗收獲機(jī)、輕量化甘蔗收獲機(jī)和蔗葉方捆壓捆機(jī)，并在廣西、云南等多地開展了應(yīng)用示范，在關(guān)鍵技術(shù)攻關(guān)、系統(tǒng)與樣機(jī)研制、田間示范應(yīng)用與推廣方面，完成了項(xiàng)目預(yù)期目標(biāo)。
 
甘蔗收獲機(jī)無人駕駛協(xié)同作業(yè)系統(tǒng)
 
甘蔗收獲機(jī)自主作業(yè)系統(tǒng)
 
　　沈陽自動(dòng)化所數(shù)字工廠研究室科研團(tuán)隊(duì)突破了甘蔗收獲機(jī)與田間轉(zhuǎn)運(yùn)車主從協(xié)同導(dǎo)航控制、切頂高度反饋控制、負(fù)荷反饋控制等9項(xiàng)技術(shù)，研發(fā)了甘蔗收獲機(jī)與田間轉(zhuǎn)運(yùn)車協(xié)同作業(yè)系統(tǒng)和甘蔗收獲機(jī)自主作業(yè)系統(tǒng)。
 
　　科研團(tuán)隊(duì)基于北斗衛(wèi)星定位系統(tǒng)，通過無線自組網(wǎng)絡(luò)將無人駕駛甘蔗收割機(jī)與田間轉(zhuǎn)運(yùn)車相連接，實(shí)現(xiàn)協(xié)同控制，其橫向誤差不超過10cm。所研發(fā)的自主作業(yè)系統(tǒng)具有切頂高度自適應(yīng)反饋控制、割臺(tái)仿形控制等功能，宿根破頭率為6.9%，含雜率為6%，與國(guó)外龍頭企業(yè)同類機(jī)型(凱斯A4000)已公開數(shù)據(jù)相比較，本產(chǎn)品在宿根破頭率、含雜率和純作業(yè)效率等方面性能均達(dá)到了國(guó)外標(biāo)桿機(jī)型同等水平。
 
　　該項(xiàng)目在廣西、云南等多地開展了應(yīng)用示范，示范面積9845畝，通過了廣西農(nóng)業(yè)機(jī)械化服務(wù)中心鑒定站的推廣鑒定。
