摘　　要：基于多维DTW和动态决策的模式识别算法,为分布式光纤传感器触发信号的模式识别提供了一种新的方法。在模式识别的过程中,动态决策结合多维DTW能够有效地解决分布式光纤传感系统的频谱周期性"陷落"问题,并解决了同类型触发因位置不同其频谱不同的识别问题。同时,实现了模板的动态增加,增强了实际应用性能。A new model identification method, which is multi-scale DTW with dynamic decision arithmetic, for distributed fiber sensing system is proposed. In the process of model identification, the problem of periodical subsidence of frequency is solved. And for the same type of model, the problem of frequency difference caused by position difference is solved. Meanwhile, the performance of the system is enhanced by dynamic model-added arithmetic.
