农机导航自动驾驶系统具有提高土地利用率、节省油耗和降低劳动力成本等优点。介绍了国内外自动导航驾驶技术的研究现状,基于京郊地区农机自动导航驾驶技术的应用试验,对自动导航驾驶技术的直线度及邻接行宽两项参数进行了分析。试验结果表明,自动导航驾驶直线度及邻接行宽工作质量均明显优于人工驾驶,邻接行宽误差最高为1.482 cm,土地有效利用率提高5.96%。同时,对北京地区推广应用农机自动导航驾驶技术提出了建议。
Automatic navigation system of agricultural navigation has the advantages of improving land utilization, saving fuel consumption and reducing labor costs. This paper introduces the research status of automatic navigation driving technology at home and abroad. Based on the application of automatic navigation driving technology in agricultural suburb of Beijing suburbs, the paper analyzes the parameters of straightness and adjacent line width of automatic navigation driving technology. The experimental results show that the driving straightness and the working quality of adjacent row width are significantly better than manual driving. The maximum error of adjacent row width is 1.482 cm and the effective utilization rate of land is 5.96%. At the same time, some suggestions are put forward to popularize and apply the automatic navigation driving technology of agricultural machinery in Beijing.
