Along with the development of cities, urban land resources are increasingly tense, the requirement of urban design on the aspect of attractiveness is considered, and high-voltage cable lines are preferably adopted for newly-built urban transmission lines. Moreover, in order to fully utilize the limited urban land and space resources, some regions even require modification of some overhead lines into underground power cable lines. Industry reports indicate that the market scale of the cable line industry in China has a 20% growth trend during five years of 2026.

With the transformation of underground cable pipelines of urban construction and old communities, if the management is not in place, the cable change information is not updated in time, so that the design drawing is not consistent with the actual wiring easily, and the difficulty of underground cable information acquisition and hidden danger troubleshooting is increased. Under the general condition, a front-line operation and maintenance worker can find out the approximate position of the hidden danger cable according to experience, but cannot accurately master the cable trend and the branch condition, the specific path and the position relation of the cable are not clear, urban underground pipelines are dense and criss-cross, and if detailed drawings and markers are not available, the path of the underground cable is difficult to master quickly and effectively. Once the underground cable is damaged by external force or has electrical faults, maintenance personnel cannot find out the faulty cable at the first time, and cannot perform troubleshooting through equipment such as an infrared thermometer and the like due to the concealment of the underground cable.

When a fault occurs, it is difficult to quickly troubleshoot and determine a fault occurrence point based on existing data, resulting in delay of maintenance.
