【摘要】：针对Ф-OTDR振动检测系统数据庞大、处理缓慢的问题,通过对硬件采集电路的设计和上位机控制软件的编写,运用FPGA高速采集技术对搭建的Ф-OTDR分布式光纤传感系统进行了优化,显著提升了系统的响应速度,从而可实现10 km光纤上振动信号的有效检测与定位,且定位误差为20 m。因此,基于FPGA技术的信号高速采集系统有助于Ф-OTDR在振动测量领域的推广和应用。
[Abstract]:Aiming at the problem of large data and slow processing of the system data , the design of the hardware acquisition circuit and the writing of the control software of the upper computer are solved , the response speed of the system is greatly improved by using the FPGA high - speed acquisition technology , so that the effective detection and positioning of the vibration signal on the 10 km optical fiber can be realized , and the positioning error is 20 m . Therefore , the signal high - speed acquisition system based on the FPGA technology can facilitate the popularization and application of the phi - otdr in the field of vibration measurement .
