摘　　要：针对低空经济中资源受限对无人机执行全任务链效率和成功率降低的问题,提出一种基于多无人机协作与语义复用共享的低空经济任务执行策略。该策略将多模态信息编码为语义向量,以减轻存储资源的负担。同时,利用多层基站进行任务信息卸载和新数据获取,实现决策信息的重复利用,减少能源消耗。此外,针对不同高度层无人机长期作业导致的语义映射偏差,单一信息经过语义调整后可在不同层无人机的知识库中重复利用,实现语义复用,减少数据冗余,进一步降低计算功耗。仿真结果表明,该策略将无人机在不同高度层的平均功耗降低了25.7%,并在此基础上使其在低空经济活动任务链中的完成率提高了53%。To address the issue of reduced efficiency and success rates in executing the full mission chain of drones due to resource constraints in the low-altitude economy,a low-altitude economy task execution strategy based on multi-drone collaboration and semantic reuse and sharing is proposed.This strategy reduces the burden on storage resources by encoding multi-modal information into semantic vectors.Additionally,by utilizing multi-layer base stations for task information offloading and new data acquisition,the strategy enables the reuse of decision information,thereby reducing energy consumption.Furthermore,to address the semantic mapping bias caused by long-term operations of drones at different altitude layers,after semantic adjustment,a single piece of information can be reused across knowledge bases of different levels of unmanned aerial vehicles,achieving semantic reuse,data redundancy reducing,and further computational power consumption decreasing.Simulation results show that this strategy reduces the average power consumption of drones at different altitude levels by 25.7%,and on this basis,increases their completion rate in low-altitude economic activity task chains by 53%.
