In order to solve the external damage of power transmission lines in mining area caused by complex weather conditions,a moni-toring system based on OPGW optical fiber strain analysis is constructed.The passive infrared detector is used to form the envi-ronment monitoring module.The video monitoring equipment installed inside the power transmission line in the mining area is a spherical camera to realize 360°full angle monitoring.The central processing module is composed of arm and DSP to match the database information and realize data analysis.The OPGW optical fiber strain analysis technology is applied to analyze the opti-cal fiber communication signals,determine the disaster location of the transmission line,monitor the moving targets,trees and mountain fires around the line,and give an alarm in time when problems are found.The experimental results show that the strain coefficients obtained by OPGW optical fiber strain analysis technology are basically consistent with the original data,and can well monitor the transmission lines in the mining area affected by the external damage disaster.
