AI Technical Summary

Technical Problem

In the prior art, handheld optical power meters have problems such as high operating risks, lack of real-time and foresight, and lack of rapidity.

Method used

A method for monitoring the optical path state in the substation is provided. By obtaining the working state and optical power of each pigtail on the distribution frame, it is determined whether the pigtail is in a critical state, and whether the overall optical path is in a total critical state is determined based on the number of critical states, and corresponding alarm information is issued.

Benefits of technology

Real-time monitoring of the optical path status in the substation is realized, which can warning of potential faults in advance, reduce the risk of optical attenuation measurement, and is fast and efficient.

Abstract

The invention provides a method for monitoring the state of an optical path in a transformer substation and a related device. The monitoring method comprises the following steps: acquiring the working state and optical power of each tail fiber on a distribution frame; determining whether each tail fiber is in a critical state based on the working state and the optical power; when the tail fiber is in a critical state, light intensity critical warning information is sent out; based on the number of the tail fibers in the critical state, determining whether an overall optical path formed by each tail fiber is in a total critical state; when the whole light path is in the total critical state, light intensity critical total warning information is sent out. According to the method for monitoring the state of the optical path in the transformer substation, the state of the optical path in the transformer substation can be monitored in real time, pre-intervention is facilitated to solve fault hidden dangers, and predictability is achieved; the risk of light attenuation measurement is reduced; the real-time performance is realized; and rapidity is realized.
