“…Temperature can effectively reflect the running state of the overhead lines, which needs to be monitored. ADSS (all-dielectric self-supporting cable) [5][6] is more and more extensively used in distribution IoT in electricity. Brillouin scattering-based optical fiber distributed sensing technology [7] can easily monitor the temperature for the optical fiber at one time, and this method avoids the need for additional sensors.…”

In order to decrease time of temperature measurement for optical fiber in ADSS (all-dielectric self-supporting cable) of distribution IoT (Internet of Things) in electricity, the slope-assisted method is applied to its temperature demodulation. According to the introduction of the Brillouin scattering-based optical fiber temperature measurement method, the basic principle of Brillouin frequency shift measurement method based on the spectra fitting algorithm and the slope-assisted method is analyzed. Based on simulated Brillouin spectra with different signal-to-noise ratios (SNRs), the measurement time and accuracy of the spectra fitting algorithm and the slope-assisted method are compared. The results indicate that when if the SNR of Brillouin spectra is not less than 35 dB, the mean error of temperature measurement by the slope-assisted method is less than 0.5°C, which is slightly larger than the error of the spectra fitting algorithm, but the spectra measurement time is only 1/17 of that of the latter.
