Application Strategy of PLC Technology in Energy-Saving Control of Tunnel Lighting

In this study, we investigated on the application of planar lightwave circuit (PLC) technology in energy-saving control of tunnel lighting. The application status of PLC in the field of energy saving followed by the necessity of energy saving in tunnel lighting was analyzed. Finally, the application of PLC in tunnel lighting energy-saving control around the three dimensions of system overall architecture design, control scheme, and program control process was investigated. The results showed that the system meets the requirements of control effect, robustness, and visual effect after trial operation, and is suitable for practical applications.
