Abstract

The invention discloses a fault detection method, device and system for a communication line. The method comprises the steps: adopting a target test mode to test a communication line, and obtaining atest result, wherein the target test mode comprises at least one of roll call test, period test, optical power test, fault trigger test and external equipment alarm linkage test; determining fault positioning information in the test result; and determining corresponding early warning information based on the fault positioning information. The technical problems that in the prior art, faults of a communication line cannot be accurately and effectively detected, and production safety and stable operation of a power system are affected are solved.

Description

technical field [0001] The present invention relates to the field of fault detection, in particular to a fault detection method, device and system for communication lines. Background technique [0002] Under the situation of the rapid development of smart grid, the distribution of communication optical cable lines is becoming wider and wider. Due to the characteristics of wide area, long line, high altitude, wild, and two high spans, the power communication optical cable lines are easily damaged by external forces and are growing rapidly. Optical cable lines have brought more and more inspection and maintenance work to line operation and maintenance personnel, but observation and inspection of dangerous points of lines in places such as crossings, densely populated areas, and natural disaster areas are essential. [0003] At present, the operation and maintenance of power communication optical cable lines mainly rely on manual intermittent inspections, and the general inspec...
