Abstract :
Distributed optical fiber temperature measurement technology could shield the interference of a strong electromagnetic field and apply to the field of high voltage. From the signal characteristics of weak and low signal-to-noise ratio, digital accumulate seeking arithmetic average and queue filtering were used to improve the measurement accuracy of the system, which achieved better test results.
