In order to improve the fault location performance of power communication optical cable line,an intelligent fault location system of power communication optical cable line based on GIS technology is designed.It builds the system hardware network architecture,describes the internal structure of the optical time domain reflectometer,analyzes the schematic diagram of the detection process of the optical time domain reflectometer,uses the formula to calculate the optical cable line length,and obtains the measured OTDR curve.In terms of software design,the remote sensing data of communication optical cable lines and other information are transformed,spliced and vectorized,and then the digital transformation of GIS map is completed.According to these data,the intelligent fault location algorithm is designed.The test results show that the deviation between the fault location results of the designed system and the actual values is small,and the high-precision fault location results of power communication optical cable lines are obtained.
