Objective: To improve the remote inspection capability of substations, a remote inspection scheme for substations based on VR (virtual reality) technology is proposed. To meet the high bandwidth and low latency data transmission requirements of this scheme, key technologies for 5G (fifth generation mobile communication technology)+VR and 5G+WiFi application are proposed. Method: The technical characteristics of VR, 5G and WiFi are analyzed, and the remote inspection scheme for substations based on VR technology is introduced. The key technologies for 5G+VR application, such as 5G network slicing, intelligent edge computing, and 5G CPE (customer premises equipment) in display terminals are covered. The senseless authentication technology and green energysaving communication strategy of 5G+WiFi converged networking are delved into, focusing on the data transmission process and computational framework of intelligent edge computing. Result & Conclusion: The remote inspection scheme for substations based on VR technology addresses many drawbacks in manual inspection. 5G technology effectively fulfills the data transmission requirements of high bandwidth and low latency. The 5G and WiFi converged networking not only improves network utilization rate and reduces latency, but also resolves issues related to terminal switching, terminal network selfdiscovery, and automatic configuration in various mobile terminal scenarios, ultimately enhancing user experience.
