摘要
根据分布式光纤温度传感器被测信号的特殊性,在常规微弱信号检测的基础上,提出了一种专门的、针对分布式光纤温度传感器系统的微弱信号检测方案,采用软、硬件结合的方案,能够在强噪声下有效地提取微弱信号,以求得尽可能大的信号噪声比,而所需的器件与设备极为通用,相对成本较低,检测整个过程完成的时间也较短,具有较高的实用性。
According to the particularity of the detected signals by distributed optical fiber temperature sensor, a weak signal detection scheme specially for distributional optical fiber temperature sensor system is presented based on the conventional weak signal detection method. By combining software and hardware, weak signal can be effectively extracted from strong noises to achieve higher signal-to-noise ratio. The components and devices in this scheme are general with lower cost, and the whole detection time is short.
