This work proposes a temperature-based power cable grounding wire anti-theft monitoring device method. Through single-mode long-distance optical fiber temperature measurement and long-distance optical fiber vibration analysis, the integrated real-time online monitoring of cable trench ambient temperature and cable anti-theft based on single-mode communication optical fiber is studied. Fundamentally solve the problem of timely detection, location and early warning of external force damage to power cables, and early detection of abnormal temperature in the cable trench and external damage points, which can help the safe operation of power cables and management departments and personnel to detect abnormal changes in environmental temperature and theft in time The incident provides a strong technical guarantee for the safe operation of power cables. In actual application, the method can control the temperature sensing within ±2℃, and through the temperature change, the corresponding distance measured is controlled within ±5 m, so as to facilitate the monitoring of cables, and also provides a new method for future cable monitoring methods.
