摘　　要：系统分析讨论光纤布拉格光栅传感复用模式,通过研究波分复用、时分复用及空分复用模式的发展历史和现状,抽象出典型结构,建立数学模型,并总结出工程应用概况;通过分析波分复用、时分复用及空分复用模式的技术瓶颈,找出复用模式的改进方式,即3种经典复用模式的联合复用和复用结构系统的改进。最后,通过总结光纤光栅传感复用模式的发展,构建复用设计的体系结构。提出基于光纤布拉格光栅传感器实时数据提取的数字设计工程将是数字制造的一个重大科学前沿,提出光纤光栅传感复用模式的发展方向,即实现分布式传感系统、构建大规模传感网络和建立统一机理模型。Fiber bragg grating sensing multiplexing mode was systematically discussed. Through investigating the development history and the research situation of wavelength division multiplex, time division multiplex and spatial division multiplex, the typical structure was abstracted, the mathematical model was built and the engineering applications were summarized. Through analyzing the bottleneck of wavelength division multiplex, time division multiplex and space division multiplex, the improvements of multiplexing mode were found, which were the combinations between classic multiplexing mode and improvements of multiplexing structure system. Finally, through summarizing the development of fiber bragg grating sensing multiplexing mode, systematic structure was constructed. The idea that real-time data extracted process of digital design based on fiber bragg gratting sensor would be a significant scientific frontier was proposed, and the development trend of fiber bragg grating sensing multiplexing mode was also proposed, which was achieving distributed sensing system, building large-scale sensor networks and establishing a unified mechanism model.
