分布式光纤测温系统凭借其优良的系统性能和先进的技术水平成为温度监测领域的首选。从测温原理的角度出发,深入研究一般温度解调方法,提出智能解调方法以改进其存在问题和局限性。采用累加平均技术处理微弱和低信噪比的信号,提高了系统的测量准确度,取得了较好的解调效果。
Distributed optical fiber temperature measurement system with its excellent system performance and advanced technology to become the first choice for the field of temperature monitoring. From the temperature measurement principle point of view, in-depth study of the general temperature demodulation method proposed intelligent demodulation method to improve its existing problems and limitations. The use of cumulative average processing weak and low signal to noise ratio of the signal to improve the measurement accuracy of the system, and achieved better demodulation effect.
