| 中文摘要: |
| 微分干涉型光纤传感是一种新型的传感系统,可应用于长距离、强电磁干扰环境下的监控和检测.提出了一种基于小波变换的分布式光纤传感信号的识别方法,采用时域-频域能量分布算法,建立不同触发模式的模型,该识别方法可应用于研究入侵信号的模式识别,并通过大量的实际应用经验和数据验证了该方法的有效性. |
| 英文摘要: |
| Differential interference sensor system is a new type of system, which could be used in the long-distance and strong-EMI condition for monitoring and inspection.This function turns to critical especially when it is used for a real security project in which a quick response to intrusion is a must.This paper provides a wavelet-based approach to build different burst modes and identify them, which could be used for mode identification in a real project, and the approach is proved by a large number of practical experiments. |
