    摘要:

    結(jié)合CAN總線和ISO11783協(xié)議,，設(shè)計(jì)了基于處方圖的直接注入式變量噴霧機(jī)。通過田間常量和變量施藥作業(yè)試驗(yàn)分析了該直接注入式噴霧機(jī)的噴灑均勻性和精準(zhǔn)度。試驗(yàn)結(jié)果表明：直接注入式變量噴霧機(jī)噴灑均勻,，總體施藥變異系數(shù)均低于10%，適合田間施藥作業(yè),；變量作業(yè)時(shí),，與預(yù)期施藥量相差在15%以內(nèi)的作業(yè)區(qū)大于

    Abstract:

    86%。Based on CAN bus and ISO11783 protocol, a direct injection variable-rate sprayer based on the prescription map was developed with the goal of realizing precision pesticide application and improving pesticide application efficiency. The spraying uniformity and accuracy of the direct injection variable-rate sprayer was analyzed through the comparison experiments between constant-rate spraying and variable-rate spraying. The field experiments showed that the spraying variable coefficient was below 10%. On a given field, the area, on which the spray volume difference between the actual spray volume and the volume supposed was less than 15%, was up to 86% of the total.
