矩形边界条件下农机作业的方向平行路径排序优化
Sequence optimization of direction parallel path for the agricultural vehicles in field of rectangle boundary
计算机技术越来越多的应用于农业机械田间作业路径的规划优化中。本文针对规则四边形地形条件下的方向平行路径,考虑多种可能地头转弯策略及不同作业模式的农艺要求及机具自身转弯特性的情况下,寻求最优的行作业任务调度排序策略,以尽可能减少机器的地头转向距离及时间而减少作业总消耗。首先在分析现有常用转弯策略生成原理的基础上,提出2种新型转弯策略。然后将调度排序问题转化成旅行商问题(Traveling Salesman Problem,TSP),并采用贪婪算法进行求解。仿真实验结果表明,算法高效稳定,与常用习惯调度排序策略相比,转弯效率得到显著。
omputer technology is increasingly used in the path planning and optimization for agricultural machineries' field operations. In this paper, for the direction parallel paths in fields of regular quadrilateral boundary, considering a variety of possible strategies of headland turning, agronomic requirements of different operating modes and the turning characteristics of machineries, we tried to find the optimal path sequence strategies to minimize the total operating length and time of headland turning. First two kinds of new turning strategies were put forward after the analysis of the generation principle of the existing turning strategies. Then the scheduling problem was formulated into the Traveling Salesman Problem (TSP), and then the greedy search algorithm was utilized to address it. Simulation experimental results showed that the algorithm is efficient and robust, and the turning efficiency is significantly improved compared to the commonly-used scheduling and sorting strategies.
