Study On Key Problems About Energy-Saving In Intelligent Lighting Control System Of Highway Tunnel Lighting

Tunnel lighting intelligent control systems are more and more applied into highway tunnel for ensuring rode safety,energy-saving and comfortable lighting.Basing on the 16 tunnels of HeDa highway in Jilin Province,China,and aiming at the deficiency of existing system,this paper studies a more effective tunnel lighting intelligent control system.3 key problems and solutions are proposed in this paper.This paper bases on the workings-"vehicle in,light brightens;vehicle out,light darkens" of tunnel lighting intelligent control system,the system is consisted by 3 layers:data process and display layer,data communication layer,data acquire and lighting-adjusting layer.Based on the operation experiences of 16 tunnels in HeDa highway in Jilin Province,China,3 key problems and solutions are analyzed in this paper.Firstly,in order to avoid the influence of tunnel length and traffic volume on tunnel lighting adjustment frequently,a model is given,it can forecast the time using the minimum luminance level.And the effect and value of this model is discussed.Secondly,the workings of segmented lighting are designed.The effect and value of segmented lighting is discussed.The effect segmented lighting with the different length tunnel is discussed.The best choosing of segmented lighting is given.Thirdly,according to the vehicle and environment extra condition,changeless lighting mode,time lighting mode,adaptation luminance lighting mode,automatic lighting mode and combined lighting mode are designed.The workings of 5 kinds of lighting control modes are compared on the effect of energy-saving for choosing which one is worthy.The effect of tunnel lighting intelligent control system is analyzed on the cost,energy-saving and bankroll-saving.The worthy and significance of the tunnel lighting intelligent control system are analyzed.
