Power cable tunnel online monitoring based on 5G network slicing technology

The total mileage of cable tunnels in China is increasing in recent years, the maintenance and inspection costs are also increasing. Large-scale deployment of detector in cable tunnel is an efficient way to reduce maintenance cost and improve inspection efficiency. The massive detector deployment leads to new challenges for power communication networks. This study designed an online cable tunnel monitoring system based on 5G network slicing technology. Taking advantage of the characteristics of 5G technology such as high bandwidth, low latency and wide connectivity, data collected by monitoring terminals and inspection robots are transmitted to the control side in real-time. With this online monitoring system, the accurate tunnel environment monitoring, cable faults identification and potential dangers elimination are realized. This system can provide a strong guarantee for underground transmission lines operation and has significant meaning for smart grid construction.
