Monitoring system for temperature of optical cable line based on optical fiber sensing network environment

The invention relates to a monitoring system for temperature of an optical cable line based on an optical fiber sensing network environment, achieves monitoring and analysis on temperature or abnormalinformation of the optical cable line, and belongs to the technical field of Internet of things. The monitoring system mainly includes a sensing subsystem and a data acquisition processing subsystem,and places emphasis on research of the sensing subsystem. The sensing subsystem is made of optical fibers and grating information materials based on fiber-optic sensing technology and senses information to be measured through a certain number of Bragg gratings. Sensing signals are collected and processed into digital signals for transmission by the data acquisition processing subsystem. Meanwhile, the sensing signals are also stored in a monitoring database. The processed signals are input into a data management subsystem for safety evaluation by experts. Finally, a simulation experiment is performed for the monitorin
