Description
Technical Field
The invention relates to the technical field of optical cable fault maintenance, in particular to a method and a system for quickly positioning an optical cable interruption position.
Background
Currently, information transmission of the southern power grid is based on optical communication, and the optical communication is based on an optical cable. The optical cable is laid in an outdoor cable trench or on a tower and is easily damaged by various factors, such as human factors (municipal construction digging, cutting, etc.) and natural disasters (such as landslide, flood, etc.). Once the optical cable is damaged to cause the interruption of the optical cable, the safe operation of the optical cable is seriously influenced, and operation and maintenance personnel need to rapidly repair the interrupted optical cable. In the process of optical cable rush-repair, the quick positioning of the optical cable interruption position is particularly critical. The method for positioning the fault position of the optical cable commonly used for operation and maintenance of the optical cable at present is to adopt a backscattering principle of an optical time domain reflectometer OTDR, test an optical port at one side of the optical cable, and perform distance positioning on the length of the optical cable at the position where the optical cable is interrupted by using Rayleigh scattering generated when light is transmitted in the optical fiber and backscattering generated by Fresnel reflection. And according to the optical cable length of the optical cable interruption position, the operation and maintenance personnel find out the specific optical cable interruption physical position by combining optical cable drawings and operation data.
The existing method for checking the fault point of the optical cable has the following defects:
(1) outdoor routing of fiber optic cables must be known to the particular line location by an operation or maintenance person familiar with the routing of the fiber optic cable line.
(2) The optical cable length position of the optical cable interruption position can only be judged by positioning through the OTDR. The geographical location of the break point in the optical cable cannot be well determined. The length of the optical cable interruption position needs to be compared with the specific geographic position, a relatively long-distance investigation area is determined, the optical cable condition of each cable well or tower is often inspected one by one in the investigation area, and the inspection needs to consume large manpower and time.
