农作物系统本身具有显著的时空变异性,忽略作物成熟日期的差异采取相同的收获日期可能会造成实际收获产量、质量的损失,使用3S技术进行科学合理的农机调度是减少这一损失的重要前提。本文使用获取的遥感数据反演了作物的成熟日期,并在分析了农机时空调度的依据和限制条件的基础上,提出了农机时空调度问题,使用改进的遗传算法构建了农机时空调度模型和算法并使用MATLAB进行了程序实现,最后构建了基于3S技术的农机调度技术框架。
The crop system itself has significant spatiotemporal variability. Ignoring the difference of crop maturity date and adopting the same harvest date may result in the actual harvest yield and quality loss. Scientifically reasonable farm scheduling using 3S technology is an important prerequisite for reducing this loss. Based on the analysis of the basis and limitation of farm machinery space-time scheduling, this paper proposed the problem of farm machinery space-time scheduling, and built the agricultural space-time scheduling model and algorithm using improved genetic algorithm And using MATLAB to carry out the program, and finally build a 3S technology-based agricultural scheduling technology framework.
