摘要: 针对采用传统视距链或图传电台的无人机环保监测距离受限、在线传输数据量受限,以及大功率数据链无法搭载于小型环保无人机等问题,提出了一种基于3G/4G网络的多无人机环保监测任务调度的方法。首先,将3G/4G网络的时间特性与多无人机环保监测任务调度相结合,将多无人机任务调度问题建模为带时间窗的团队定向问题(TOPTW);然后,针对TOPTW求解中存在计算量大、易陷入局部最优的问题,提出一种局部迭代搜索(ILS)算法来优化求解TOPTW;其次,使用大量测试集检验该算法的可行性和运算性能,与现有的蚁群算法(ACA)比较结果的平均收益与计算时间;最后设计了3G/4G网络下典型的双机环保监测任务调度环境,并将ILS算法应用其中。仿真结果表明,与蚁群算法相比,ILS所得收益大部分都要低于ACA所得收益,所有算例收益的平均Gap为1.09%,最大值为10.8%,其中也有部分结果要优于ACA结果;计算时间平均缩减至千分之一。实验结果表明,ILS算法能快速得到多无人机任务调度序列,有效减少了计算时间而实验收益结果在可接受范围内。

Abstract: Focused on the limitation of monitoring distance, restriction of online transmission, large amount of information and that high-power data-link is disable to board small environment monitoring Unmanned Aerial Vehicle (UAV), a multiple-UAV environment monitoring task scheduling method considering 3G/4G network features was proposed. First, the time characteristic of 3G/4G network and the multiple-UAV environment monitoring task scheduling were combined, and this issue was modeled as Team Orienteering Problem with Time Window (TOPTW). Secondly, since the problem of huge computation and easily falling into local optimum, an Iterated Local Search (ILS) algorithm was proposed to get the optimization solution. Thirdly, a large amount of test data sets were applied into experiments to verify the feasibility and computing performance, and the comparative result between ILS and Ant Colony Algorithm (ACA) about the average profit and computing time were proposed. Last, the algorithm was applied in typical two UAV environment monitoring task scheduling under 3G/4G network. The results show that, the most profits received from ILS were worse than those from ACA. The average Gap of all test data sets was 1.09% and the largest was 10.8%. There were some results better than those in ACA. And the computing time of ILS was nearly reduced to a thousandth of the computing time of ACA. The experimental results show that ILS algorithm can fast solve the issue of multi-UAV environment monitoring task scheduling and effectively reduce the computing time with profit results in an acceptable scope.
