摘　　要：为了降低播种机重复作业和漏播作业的概率,提高作业的速度,降低成本,减轻驾驶员的工作量,基于DSP技术和目标模拟器地图生成技术,设计了一种新型的自主导航播种机。该播种机可以采集GPS位置点,得到目标模拟器的电子地图,然后根据目标模拟器的形状确定播种机的行驶路线,并按照确定好的规划路线对播种机的行进路径进行跟踪,对得到的采集数据进行保存。利用DSP处理技术,实现了播种机实时运动的显示功能,经过数据处理得到点状图,生成了目标模拟器的电子地图。试验证明:播种机的DSP实时编码效率、重播率及路径规划准确率等各项指标都符合自动化播种机的设计要求,为现代化播种机的设计提供了较有价值的参考。In order to reduce seeder repetitive operation and leakage sowing operations of probability,improve the operating speed,save time,reduce costs,reduce driver workload,based on DSP technology and target simulator map generation technology,it designs a new autonomous navigation seeder. The planter can collecting GPS position,get the electronic map of the target simulator,then the route of the seeding machine is determined according to the shape of the target simulator,finally according to determine a good route planning of the planter travel path tracking and data collection,save. Using DSP processing technology,the display function of the real- time motion of the seeding machine is realized,and the electronic map of the target simulator is generated by the data processing. Finally through the experiment proved that the seeder DSP real- time coding efficiency and reseeding rate and path planning accurate rate and other indicators are in line with design requirements of automatic seeder,which provides a more valuable reference for modern seeding machine design.
