基于无人机的电力故障巡检技术研究

Research on Power Fault Inspection Technology Based on UAV

针对电网线路长期暴露在外,天气变化和环境影响对输电线路造成不同程度损坏的问题,利用无人机对电力线路进行巡视。设计了一种电力巡视系统,借助四旋翼无人机搭载采集设备进行巡视。针对无人机采集的图像,利用加权平均法对不同的图像进行灰度化处理,采用滤波处理使图像效果更加清晰,并选择Sobel算子对图像实现边缘处理。实验结果表明:利用无人机进行电力巡视可以高效、省时、省力,安全完成巡视过程。

In view of the long-term exposure of the power grid lines,the change of weather and the impact of the environment have caused damage to the transmission lines to varying degrees,and drones are used to inspect the power lines.A power patrol system is designed,with a quadrotor UAV,equipped with collection equipment for patrol.For the image processing of uav,the weighted average method is used to gray-scale process different images.After filtering processing,the image effect is clearer.The Sobel operator is selected to realize edge processing for the image.The experimental results show that using drones for electric inspection can be efficient,time-saving and labor-saving,and the inspection process can be completed safely.
