Research on Energy-saving Evaluation and Intelligent Control Technology of Highway Tunnel Lighting
To quantify the energy-saving level of tunnel lighting and improve the refined control level of tunnel lighting,this article establishes evaluation indicators for tunnel lighting energy-saving from the aspects of lighting fixtures,intelligent control,quality improvement,and green technology,and creates an evaluation algorithm for tunnel lighting energy-saving,and proposes a tunnel lighting threshold control model based on multiple parameters,which real-time correlates the brightness inside and outside the tunnel,vehicle speed,and traffic flow parameters,and considers the effects of season and weather,tunnel length,and alignment parameters.Lighting control strategies under different working conditions are developed.The digital twin technology is applied to reproduce real-time tunnel traffic flow status and lighting control parameters.In combination with digital control technology,a visual intelligent control system with functions such as auxiliary decision-making and lighting quality evaluation is developed to achieve dynamic scene perception and intelligent control of tunnel lighting,guide energy-saving construction and operation management of highway tunnel lighting,and effectively improve tunnel lighting quality and service level.
