摘　　要：文中针对目前研究中广泛采用的分立式系统设备在应用中存在的实时性、互联性以及效率等方面的诸多问题,研究提出了基于标准化通用总线平台的模块化集成主动Lamb波结构健康监测系统。用总线平台的开放性,集成系统运行所需的硬件设备,并构建监测系统的软件平台;同时,研究了标准化压电传感器及其网络控制技术。对系统设计方案进行了设计验证和实验研究,实验结果表明,该系统具备良好的开放性、实时性和兼容性,基本满足在线主动Lamb波结构健康监测应用化要求。To resolve the problems existed in most of current experimental systems which were usually composed of independent devices, such as real-time performance, inter-telecommunication and efficiency, an integrated and modularized active Lamb wave SHM system and its software based on standardized gen- eral BUS platform technique was proposed. This system can integrate all the necessary devices for the ap- plication conveniently for its openness character. At the same time, standard PZT sensor and sensor net- work control technique were also researched. Validation for the system design was conducted by experi- ments. The experimental results indicated that the proposed system can fulfill the application requests of the online active Lamb wave SHM with good openness, timeliness and compatibility.
