Problems solved by technology

However, the change of external temperature and stress will also have a significant impact on the Brillouin scattering translation effect of the optical signal on the OPGW, making this method poor in anti-interference ability. Therefore, it is still in theoretical research and lacks practical feasibility.
The second method is based on the sensing technology of OPGW light polarization state, which is currently mainly in the theoretical stage and lacks practical demonstration.

Abstract

The invention relates to an optical ground wire (OPGW) optical fiber polarization detection system based on handshake time synchronization. The OPGW optical fiber polarization detection system comprises a first main machine and a second main machine, wherein the first main machine and the second main machine are connected through an OPGW and are respectively deployed in different units at two endsof the OPGW. The OPGW sensing optical fiber is directly multiplexed in optical signal handshake time synchronization, and the time synchronization error is accurately measured through sensing opticalhandshake at the two ends, so that the time synchronization precision is improved.

Description

technical field [0001] The invention relates to the technical field of optical fiber sensing, in particular to an OPGW optical fiber polarization detection system and a time synchronization method based on handshake time synchronization. Background technique [0002] Optical fiber composite overhead ground wire (OPGW) is a new type of ground wire that has emerged in recent years. It is used as both a lightning protection line and a communication trunk line. Due to its own communication characteristics, the lightning strike location can be performed through the OPGW itself. [0003] At present, there are few studies on the lightning strike detection of transmission lines based on OPGW at home and abroad, mainly Japanese scientists have carried out some theoretical research, and produced two major technical directions, one is the sensing technology based on Brillouin scattering, and the other is Sensing technology based on the polarization state of light. In the first method...
