Optical Cable Fault Accurate Location Method Based on VR-GIS

Aiming at the problem of inaccurate positioning of optical cable fault monitoring method, an optical cable fault locating method based on VR-GIS (virtual reality geographic information system) is proposed, a virtual optical cable line model is built, and a software platform for optical cable fault monitoring and management based on VR-GIS is developed. The effectiveness of the proposed method is demonstrated with an experimental circuit. Experimental analysis shows that the proposed method has high positioning accuracy and short time, the positioning error is less than ±15m, and the positioning time is only 5.9 seconds.
