Abstract

The invention discloses a power cable safety monitoring system in a tunnel. The system includes: several optical fiber sensors, transmission optical fibers, and a signal processor; Collect and transmit the collected signal to the back-end signal processor through the transmission fiber. The signal processor judges whether there is any abnormality in the power cable based on the vibration signal collected by the optical fiber sensor. If there is an abnormality, it will send an alarm message to the preset terminal Solve the problems existing in the existing manual inspection, and realize the technical effect of intelligently and automatically monitoring the safety of the power cables in the tunnel through the power cable safety monitoring system in the tunnel.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a power cable safety monitoring system in a tunnel. Background technique [0002] In the power system, the power cable undertakes the important task of power transmission and data transmission. Therefore, the safety monitoring of the power cable is particularly important, especially the power cable in the tunnel. Due to the complex geology in the tunnel, it is prone to collapse, collapse, etc. Geological disasters. Therefore, traditional transmission cable monitoring in tunnels mainly uses manual inspections, which is inefficient and difficult to detect problems in advance, because some geological disasters occur slowly, and the initial address deformation is small, and There are certain potential safety hazards, such as sending landslides during inspections and so on. Contents of the invention [0003] The invention provides a power cable safety monitoring system in a tunnel, whi...
