Huidong Tang, Duo Li, Wendong Lei, Jinpeng Meng
The conventional automatic identification algorithm of double-feature fault signal waveform of power equipment mainly uses ART (Adaptive Resonnance Theory) network for classification and discrimination, which is easily influenced by the identification mapping relationship, resulting in low correct identification rate of fault signal waveform. Therefore, it is necessary to design a brand-new automatic identification algorithm of double-feature fault signal waveform of power equipment. That is to say, the waveform characteristics of dual-feature fault signal of power equipment are extracted, and the optimization algorithm for automatic identification of dual-feature fault signal waveform of power equipment is generated, so that the automatic identification of fault signal waveform is realized. The experimental results show that the designed double-feature fault signal waveform automatic identification algorithm for power equipment has a high correct fault identification rate, which proves that the designed double-feature fault signal waveform automatic identification algorithm for power equipment has good identification effect, reliability and certain application value, and has made certain contributions to improving the operation safety of power equipment.

Lightweight person re-identification model employing symmetrical combination units 采用对称组合单元的轻量级人员再识别模型
dawei cai, qingwei tang
As an image retrieval problem, person re-identification (Re-ID) relies on robust features extracted by convolution neural models. Most current methods use large backbone models for feature extraction (e.g., ResNet50). However, these large backbone models have many parameters, which cause many problems when embedded in smart camera devices. For example, the device's computing resources are limited, the real-time operation speed is limited, etc. So it is necessary to construct models with low parameters and low complexity. This paper proposes a new lightweight baseline for Re-ID, which is SCL-net and all underlying modules of the model are reconstructed. In our work, we design a new convolution unit----symmetrical combination units (SC-unit), which construct features map of richer channels by reusing feature maps from different convolution layers. In addition, we redesigned all the base modules of SCL-net and proved the effectiveness of all modules. We joint training of shallow and deep features of the model respectively to improve the accuracy of the model. Our SCL-net has about 2.3M parameters, and it can achieve 95.2%/85.9% on Rank-1 and mAP without any pretraining.
作为一个图像检索问题,人员再识别(Re-ID)依赖于卷积神经模型提取的稳健特征。目前大多数方法使用大型骨干模型进行特征提取(如 ResNet50)。然而,这些大型骨干模型有很多参数,在嵌入智能摄像设备时会产生很多问题。例如,设备的计算资源有限、实时运行速度有限等。因此,有必要构建低参数、低复杂度的模型。本文提出了一种新的轻量级 Re-ID 基线,即 SCL-net,并对模型的所有底层模块进行了重构。在我们的工作中,我们设计了一个新的卷积单元----symmetrical combination units(SC-unit),它通过重复使用不同卷积层的特征图来构建更丰富的信道特征图。此外,我们还重新设计了 SCL 网络的所有基础模块,并证明了所有模块的有效性。我们分别对模型的浅层和深层特征进行了联合训练,以提高模型的准确性。我们的 SCL-net 有大约 230 万个参数,在没有任何预训练的情况下,它在 Rank-1 和 mAP 上的准确率分别达到了 95.2% 和 85.9%。

Research on electrical contact performance based on machine vision 基于机器视觉的电接触性能研究
Chun-lin Li, Yangxin Ou, Lei You, Zewu Zhang
The electrical connection serves as a vital and abundant link in power, electronic equipment, and systems, with the electrical contact acting as its core component. In practical working conditions, fretting wear occurs during the usage of electrical contacts, leading to surface destruction and a decline in their performance. Determining the degree of wear on electrical contacts is crucial for assessing their failure in engineering applications. This study focuses on conducting fretting wear tests on copper material under different cycles for electrical contacts while utilizing machine vision algorithms to detect the morphological characteristics of wear marks. Gray threshold segmentation is applied to extract texture features from wear marks after various oxidation conditions. Pseudocolorization techniques are employed to process extracted morphologies, followed by calculating their characteristic areas. Finally, combining these results with contact resistance curves allows for judging the electrical conductivity of the electrical contact under different cycles.

Jinhao Wang, Jizhuang Hui, Yaqian Zhang, Tao Zhou, Kai Ding
Aiming at multi-target detection in complex human-robot collaborative assembly scenes, an improved YOLOv7 algorithm is proposed. Specifically, the Wise-Intersection over Union(Wise-IoU) loss function and the BiFormer attention module are introduced to improve the recognition performance of small assembly parts. Taking a worm-gear decelerator as an example, a dataset for assembly parts recognition is made. By training the improved network in the self-made dataset, the mAP@.5 value is increased by 3.25 % and the average total loss is reduced by 0.02365. The experiment results show that the improved YOLOv7 algorithm can achieve multi-assembly parts detection in collaborative assembly.

Xingshuai Zang, Shengnan Zhang, Yu He
In response to the thin nature of hot rolled steel plates and strips, the vast majority of which are surface defects that can easily lead to production accidents, and limited by the challenges of insufficient datasets and a large amount of unlabeled data, this paper proposes a comparative learning method to solve the above problems. In terms of methods, a dual data augmentation strategy is adopted. Firstly, the original image is data enhanced through manual processing, and CycleGAN is introduced for style transfer to enrich the dataset. Then, ResNet152 network is used for feature extraction, and several comparative learning methods are applied to observe the accuracy of hot rolled strip defect detection. In the end, the improved comparative learning method in this article successfully improved the accuracy of surface defect classification for hot rolled strip steel. Through this research, we are committed to providing more reliable quality control methods for industrial production and reducing the risk of production accidents.

An improved dung beetle optimizer 改进的蜣螂优化器
Jinxiang Feng, Jingyang Li, Yufeng Zhang, H. Baoyin
Dung Beetle Optimizer(DBO) is an effective metaheuristic algorithm proposed in 2022. But at the same time, DBO also suffers from a local-global imbalance in the exploration process, tends to fall into local optimization and exploitability needs to be further improved, etc. Therefore, we propose an improved DBO algorithm to address these shortcomings and named it CDBO. Firstly, Tent chaotic mapping can be used for the purpose of initializing the population, improving the quality of initial solutions, promoting the enhancement of population variety, and augmenting the global search capability of the algorithm. Secondly, introducing dynamic weighting factors enables the algorithm to fully search for local areas while also taking into account global exploration. To assess the effectiveness of CDBO, a total of 12 benchmark test functions were utilized to evaluate the performance of this algorithm, wherein CDBO was compared with other widely recognized metaheuristic algorithms. The results showed that CDBO had improved search accuracy and convergence speed. Finally, CDBO was applied to airfoil optimization problem, verifying the feasibility of applying CDBO to practical engineering problems.
Dung Beetle Optimizer(DBO)是2022年提出的一种有效的元启发式算法。但同时,DBO也存在探索过程中局部与全局不平衡、容易陷入局部优化、可利用性有待进一步提高等问题。因此,针对这些不足,我们提出了一种改进的DBO算法,并将其命名为CDBO。首先,Tent 混沌映射可用于初始化种群,提高初始解的质量,促进种群多样性的提高,增强算法的全局搜索能力。其次,引入动态加权因子可以使算法在充分搜索局部区域的同时兼顾全局探索。为了评估 CDBO 的有效性,我们使用了 12 个基准测试函数来评估该算法的性能,并将 CDBO 与其他公认的元启发式算法进行了比较。结果表明,CDBO 提高了搜索精度和收敛速度。最后,将 CDBO 应用于机翼优化问题,验证了将 CDBO 应用于实际工程问题的可行性。
