分布式光纤振动传感信号的采集与处理

Acquisition and Location of Distributed Optical Fiber Vibration Signal

以分布式振动传感在周界安防中的应用为研究对象,简述了一个全光纤扰动传感与定位系统。分布式光纤传感与定位系统主要由光发射模块,传感光路模块,光接收模块,信号采集模块,信号传输模块及信号处理模块构成。振动信号的采集与处理决定着系统报警及定位的实时性和准确性,主要研制了振动传感系统中的数据采集与处理系统。

Detecting and locating intrusions have important practical significance in modern security and defense system.in this paper,a sensing and locating system based on distributed optical fiber is described.System hardware mainly consists of optical transmitter,optical sensing fiber,optical receiver module,the data acquisition and transmission module and the Signal processing module.Vibration signal acquisition and processing system determines the feature of real time response and accuracy of the alarm and location.This paper developes a data acquisition and processing system in a vibration sensor system.
