Intelligent Control and Energy-saving Analysis of Highway Tunnel Lighting Combined with Side Wall Coating
In order to ensure driving safety and reduce tunnel lighting energy consumption,a new intelligent control method of highway tunnel lighting combined with side wall painting is proposed.Firstly the relationship between the influencing factors of lighting design,the average brightness of the road surface and the power of the luminaire is obtained,based on the calculation model of tunnel lighting parameters,.Secondly,the FRBF neural network is used as the control algorithm,the brightness outside the tunnel,the speed and the traffic volume are taken as the input variables,and the control power of the lamps combined with the side wall painting is taken as the output variables.The intelligent lighting control model is built based on the tunnel field data.The test results show that it has good generalization ability.Furthermore,the expected energy-saving effect of the model is evaluated.The results show that the control model combined with side wall painting can achieve 9.08%energy saving compared with the fixed power in the Guidelines for Design of Lighting of Highway Tunnels(JTG/TD70/2-01-2014).The energy saving effect can be maximized under the premise of meeting the lighting demand.The research results can provide theoretical basis for tunnel lighting design.
