摘要/Abstract

摘要： 为提高大田苗期作物施药过程中的农药利用率，减少作物行间的农药残留，减轻驾驶者的疲劳程度，通过系统设计，搭建高地隙喷雾机的导航系统、供药系统，设计对行控制系统。根据作物种植要求，对行系统关键部件进行参数分析与选型设计，面向系统性能进行试验研究。试验结果表明，供药系统可对喷雾压力、流量进行监测，调节，在场地得到实际流量与目标流量的平均相对误差在±5.4%以内，导航系统可对作物进行初步对行，并且导航作业速度在0.5 m/s的平均偏移为2.46 cm，田间对行控制系统的总体对行偏差均值为5.78 cm，喷雾性能试验得到对行施药系统总体节药为10.14%。

Abstract: In order to improve the utilization rate of pesticide during crop application in seedling stage, save pesticide residues between crop rows, and reduce the fatigue degree of drivers, autonomous navigation system and pesticide supply system of the high clearance sprayer were built through the system design, and the row‑oriented spraying control system was designed. According to the requirements of crop planting, parameters analysis and selection design of key components of the row system were carried out, and experimental research was carried out for the performance of the system. The experimental results showed that the average relative error between the actual flow and the target flow was within ±5.4% when the spray pressure and flow were monitored and adjusted by the drug supply system. The platform navigation system could preliminarily align crop rows, and the average deviation at navigation speed of 0.5 m/s was 2.46 cm, and the average deviation of row‑oriented control system was 5.78 cm. The spraying performance test was carried out, and the overall saving rate of the application system was 10.14%.
