摘要

摘要: 煤矿工业物联网（IIoT）设备计算与存储资源受限，易遭受非法网络入侵，造成敏感数据泄露或恶意篡改，威胁煤矿生产安全。精准识别煤矿IIoT设备可实现有效管理并维护设备正常运转，提高设备安全防护能力，然而现有设备识别算法存在特征构造复杂、内存与计算需求较高导致难以部署在资源受限的煤矿IIoT设备中等问题。针对上述问题，提出了一种煤矿IIoT设备识别模型。首先，对支持TCP/IP协议传输的流量数据进行流量切分、无关字段去除、去重、定长字段截取操作后转换为IDX格式存储；其次，使用卷积块注意力模块（CBAM）优化深度可分离卷积（DSC），从而搭建轻量级DSC−CBAM模型来过滤Non−IIoT设备；然后，利用带有阶段惩罚的Wasserstein生成对抗网络（WGAN−GP）扩充流量较少的煤矿IIoT设备数据，达到平衡偏移流量数据的目的；最后，在DSC−CBAM基础上引入多尺度特征融合（MFF）技术捕获浅层全局特征信息，并增加Mish激活函数提高模型训练稳定性，建立优化混合模态识别（MDCM）模型，实现煤矿IIoT设备精准识别。实验结果表明，该模型收敛速度快，准确率、召回率、精确率与F1−score指标均高达99.98%，且参数量小，能精准、高效识别煤矿IIoT设备。

Abstract: The computing and storage resources of the industrial Internet of things (IIoT) equipment in the coal mine are limited, making it vulnerable to illegal network intrusion, causing sensitive data leakage or malicious tampering, and threatening the safety of coal mine production. Precise recognition of coal mine IIoT equipment can achieve effective management and maintenance of equipment operation, improve equipment safety and protection capabilities. However, existing equipment recognition algorithms suffer from complex feature construction, high memory and computing requirements, making it difficult to deploy in resource limited coal mine IIoT equipment. In order to solve the above problems, a coal mine IIoT equipment recognition model is proposed. Firstly, the model performs traffic segmentation, irrelevant field removal, deduplication, and fixed length field truncation operations on traffic data that supports TCP/IP protocol transmission. The model then converts it to IDX format for storage. Secondly, the model uses convolutional block attention module (CBAM) to optimize depthwise separable convolu-tion(DSC). A lightweight DSC-CBAM model is constructed to filter Non-IIoT equipment. Thirdly, the Wasserstein generative adversarial network with gradient penalty (WGAN-GP) is used to expand the data of coal mine IIoT equipment with less traffic, achieving the goal of balancing offset traffic data. Finally, multi-scale feature fusion (MFF) technology is introduced on the basis of DSC-CBAM to capture shallow global feature information, and Mish activation function is added to improve model training stability. The MFF-DSC-CBAM-Mish (MDCM) model is established to achieve precise recognition of coal mine IIoT equipment. The experimental results show that the model has a fast convergence speed, with accuracy, recall, precision, and F1 score all reaching 99.98%. The model has a small number of parameters, which can accurately and efficiently recognize IIoT equipment in coal mines.
