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。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 intrusion is a must. This paper provides a wave modes and identify them, which could be used for approach is proved by a large number of practical security project in which a quick response to let based approach to build different burst mode identification in a real project, and the experiments.
