2022年辽宁省绕阳河溃口无人机应急监测分析

Emergency monitoring and analysis of unmanned aerial vehicles for the breach of the Raoyang River in Liaoning Province in 2022

无人机因其具有使用简便、机动灵活、数据分辨率高、成本低等优势,在防汛应急抢险中发挥着重要作用。2022年汛期,辽宁省绕阳河发生有水文记录以来的最大洪水,同时河道水位长期超警戒,曙四联段发生了溃口险情。将无人机应用于绕阳河溃口险情中,执行应急测量、巡河巡堤、航拍等任务,对3个无人机应用场景进行了详细阐述,提出了防汛应急监测无人机应用建议,为今后的险情应急监测提供参考。

Unmanned aerial vehicles(UAV) plays an important role in flood control emergency rescue due to its advantages of easy use, flexibility, high data resolution and low cost. In the flood season of 2022, the largest flood occurred in the Raoyang River in Liaoning Province since the hydrological records. At the same time, the water level of the river channel exceeded the warning for a long time, and the Shusilian section of the Raoyang River broke out. The UAV was applied to the dangerous situation of the Raoyang River breach, and the tasks of emergency survey such as river patrol and dike patrol,aerial photography, etc. were carried out. The three UAV application scenarios were described in detail, and the application suggestions of the UAV for flood emergency monitoring were put forward, providing reference for the future emergency monitoring of dangerous situations.
