中文摘要:

针对海上风电支撑结构在严酷海洋环境中长期运行的安全运维难题，本文设计并开发了一套基于振动频谱分析的智能健康监测系统。该系统通过创新的抗干扰硬件设计、自适应边缘-云端协同架构及智能化数据分析流程，实现了对恶劣环境下结构振动信号的自动采集、远程传输与结构损伤的自动识别。本文重点阐述了系统的整体设计思路、关键硬件选型与软件平台架构，并详细介绍了其在东北淤泥质海域与南海台风海域两个典型海上风电场中的长期工程应用案例。应用结果表明:该系统能够有效捕捉因基础淤积和螺栓连接松动等典型损伤引起的结构振动频谱特征变化，监测预警结果均得到现场核查验证。本文工作为海上风电结构的安全运维与预防性维护提供了系统的技术解决方案与实践参考。

英文摘要:

To address the safety and maintenance challenges of offshore wind turbine support structures operating long-term in harsh marine environments, an intelligent structural health monitoring (SHM) system based on vibration spectrum analysis was designed and developed. This system achieves automatic acquisition, remote transmission of structural vibration signals in harsh environments and automatic identification of structural damage through innovative anti-interference hardware design, an adaptive edgecloud collaborative architecture, and an intelligent data analysis workflow. This paper focuses on the overall design concept, key hardware selection, and software platform architecture of the system. Furthermore, it elaborates on longterm engineering application cases in two typical offshore wind farms located in the siltladen waters of northeastern China and the typhoonprone area of the South China Sea. Application results demonstrate that the system can effectively capture characteristic changes in structural vibration spectra caused by typical damages such as foundation siltation and bolt connection loosening. All monitoring alerts have been verified through onsite inspections. The work presented in this paper provides a systematic technical solution and practical reference for the safety operation and preventive maintenance of offshore wind turbine structures.
