摘要

由于GIS设备内部结构复杂且空间全封闭，图像采集存在不均匀光照和细节模糊等问题，容易在状态监测时引发漏检和误检，为此，提出一种轻量化语义分割模型GIS-SegFormer。首先，采用CGLU模块替换原SegFormer模型前两层Transformer Block中的MSA，解决自注意力机制忽略局部特征问题；其次，引入AFE模块增强光照不足环境下的特征提取能力；此外，通过嵌入DySample模块动态调整上采样核参数，进一步优化了上采样过程。在自制的GIS隔离开关数据集上进行的实验结果表明，相较于原SegFormer模型，GIS-SegFormer的mIoU提升2.82%，mPA提升0.88%，mPrecision提升2.17%，mRecall提升0.88%。同时，GIS-SegFormer模型的参数量仅为5.191×10

，便于在实际监测系统中部署应用。改进的GIS-SegFormer模型应用到GIS隔离开关监测系统中，可以精准地识别出隔离开关的状态，提高GIS设备运行的安全性与维护效率。

Abstract

Due to the complex internal structure and fully enclosed space of GIS equipment

image acquisition suffers from such issues as non-uniform illumination and blurred details

which can easily lead to missed detections and false detections during status monitoring. To address this

a lightweight semantic segmentation model named GIS-SegFormer is proposed. First

the CGLU module is adopted to replace the MSA in the first two Transformer Blocks of the original SegFormer model

addressing the issue of self-attention mechanisms overlooking local features

. Then

the AFE module is introduced to enhance feature extraction capability in low-light environments. Additionally

the DySample module is embedded to dynamically adjust upsampling kernel parameters

optimizing the upsampling process further. Experimental results on a self-constructed GIS disconnector dataset show that compared with the original SegFormer model

GIS-SegFormer achieves an increase of 2.82% in

mIoU

0.88% in

mPA

2.17% in

mPrecision

and 0.88% in

mRecall

. Meanwhile

the GIS-SegFormer model contains only 5.191×10

parameter

making it convenient for deployment and application in actual monitoring systems. The improved GIS-SegFormer model is applied to the GIS disconnector monitoring system

which can not only accurately identify the status of the disconnector

but also improve the safety and maintenance efficiency of GIS equipment.
