利用基于马赫-曾德尔(M-Z)干涉原理的分布式光纤振动传感监测系统,提出了一种光缆振动事件的识别方法。该方法解决了普通光纤振动传感监测系统不具备模式识别智能分析可操作性的问题。通过对光缆上的振动事件的分析对振动的事件识别建模,利用大量实验数据将振动事件分类,通过与这些振动事件的比较,实现对振动事件的识别。 Based on the distributed optical fiber vibration monitoring system based on the Mach-Zehnder interferometry principle, a method of identifying vibration events of optical cables is proposed. The method solves the problem that the ordinary optical fiber vibration sensing monitoring system does not have the feasibility of pattern recognition intelligent analysis. Through the analysis of the vibration events on the optical cable, the event identification of the vibration is modeled, and a large amount of experimental data is used to classify the vibration events. By comparing with these vibration events, the identification of the vibration events is realized.
