摘　　要：设计了机械臂式点位控制补种机构,并基于Lab VIEW提取空穴坐标,确定空穴位置。对种头运动轨迹进行组合优化算法研究,对穷举法、最近邻点策略及最短链接策略3种算法进行了3种轨迹优化试验。试验结果表明:3种算法各自绘制出的运动图形轨迹与给出的空穴位置相吻合,均能够完成精密播种的点位控制;且穷举法运行时间短,编程简单,结果精确,输出距离短,确定为最优运动轨迹算法。Designing of mechanical arm point to point motion control reseeding mechanism,and extracts the cavity coordinates successfully use Lab VIEW to determine the location of cavities. Doing combination optimization algorithm research for seeding head trail,applying exhaustive method、nearest neighbor points strategy and the shortest link strategy for three trail optimization experiments and completed the algorithm programming based on Lab VIEW software. Experimental results show that the movement trail graphics which plotted by each of the three algorithms can match the given cavities position,they are able to complete the point to point control of precision seeding,but the method of exhaustion has determined the optimal trail algorithm because of its advantages of simple programming,accurate results,and the running time is short,the output distance is short.
