摘要:

准确分析工业时间序列大数据对于工业设备的预测与健康管理(PHM)至关重要。尽管近年来大语言模型(LLMs)在时间序列分析中展现出潜力,但现有方法通常专注于单模态适应,未能充分利用时序信号、频域图像和文本知识信息的互补性。本文提出TS-MLLM,一种统一的多模态大语言模型框架,旨在联合建模时序信号、频域图像和文本领域知识。具体而言,我们首先开发了一个工业时间序列补丁建模分支以捕捉长距离时序动态。为整合跨模态先验,我们引入了频域感知视觉-语言模型适应(SVLMA)机制,使模型能够内部化频域模式和语义上下文。此外,设计了以时间为中心的多模态注意力融合(TMAF)机制,利用时间特征作为查询主动检索相关视觉和文本线索,确保深度跨模态对齐。在多个工业基准上的广泛实验表明,TS-MLLM在少数样本和复杂场景中显著优于现有最先进方法。结果验证了该框架在工业时间序列预测中的优越鲁棒性、效率和泛化能力。

英文摘要:

Accurate analysis of industrial time-series big data is critical for the Prognostics and Health Management (PHM) of industrial equipment. While recent advancements in Large Language Models (LLMs) have shown promise in time-series analysis, existing methods typically focus on single-modality adaptations, failing to exploit the complementary nature of temporal signals, frequency-domain visual representations, and textual knowledge information. In this paper, we propose TS-MLLM, a unified multi-modal large language model framework designed to jointly model temporal signals, frequency-domain images, and textual domain knowledge. Specifically, we first develop an Industrial time-series Patch Modeling branch to capture long-range temporal dynamics. To integrate cross-modal priors, we introduce a Spectrum-aware Vision-Language Model Adaptation (SVLMA) mechanism that enables the model to internalize frequency-domain patterns and semantic context. Furthermore, a Temporal-centric Multi-modal Attention Fusion (TMAF) mechanism is designed to actively retrieve relevant visual and textual cues using temporal features as queries, ensuring deep cross-modal alignment. Extensive experiments on multiple industrial benchmarks demonstrate that TS-MLLM significantly outperforms state-of-the-art methods, particularly in few-shot and complex scenarios. The results validate our framework's superior robustness, efficiency, and generalization capabilities for industrial time-series prediction.
