摘要:

目前用户侧智能电表的维护与检测主要依赖专业人员上门排查, 存在现场检验效率低、周期检定任务繁重、严重依赖人工经验等问题。基于电网巡检图片构建电表异常图像数据集, 针对电表图像背景复杂、目标尺寸不一、异常接线隐蔽遮挡等问题, 提出一种基于多样性感知的可微分自动数据增广(D-DADA)与双分支特征增强YOLO(DBE-YOLO)网络的电表异常检测方法。首先, 提出改进的DBE-YOLO网络, 通过引入级联空洞卷积增强模型对全局上下文信息与多尺度特征的提取, 设计双分支聚合结构弥补了原始模型感受野受限、卷积特征捕捉模式固定的缺陷。其次, 提出一种多样性感知的D-DADA算法, 设计了搜索策略多样性约束条件促进对更广泛数据增强策略的自动搜索, 从而帮助模型学习到不同场景、角度、光照等情况下的检测目标特征和模式, 解决数据类内差异较大导致的模型识别性能不足等问题。实验结果表明, 改进后的YOLOv8模型对8类电表异常的平均检测精度可达到79.6%, 相对于改进前提高了3.4百分点。

Abstract:

Currently, the maintenance and anomaly detection of user-side smart meters primarily rely on professionals visiting the site, leading to low inspection efficiency, significant periodic testing burdens, and dependence on manual experience. A dataset of abnormal electricity meter images is created based on the inspection images obtained from a power grid company. This paper introduces a novel anomaly detection method for electricity meters that utilizes Diversity-Driven Differentiable Automatic Data Augmentation (D-DADA) algorithm and the Dual-Branch Feature Enhancement YOLO (DBE-YOLO) network to address issues such as complex backgrounds, varying target sizes, and obscured wiring in meter images. First, the DBE-YOLO model is designed to enhance the extraction of global contextual information and multiscale features by introducing cascaded dilated convolutions. It also employs a dual-branch aggregation network to overcome the limitations of the original model, including a restricted receptive field and fixed convolutional feature capture patterns. Second, the D-DADA algorithm is introduced, featuring a search strategy with diversity constraints to enhance the automatic discovery of a wider array of data augmentation strategies. This enables the model to learn the detection target features and patterns under various scenarios, angles, and lighting conditions, addressing the issue of insufficient model recognition performance owing to large intraclass variations. The experimental results indicate that the improved YOLOv8 model achieves an average detection accuracy of 79.6% across eight types of electricity meter anomalies, representing a 3.4 percentage point increase compared with the previous version.
