Optimal Illumination Distribution Of Highway Tunnel Lighting

The tunnel lighting system is the basic guarantee for the safe operation of highway tunnel.There is a contradiction between the effect of tunnel lighting system and energy saving.The key to solving this contradiction is to optimize the illumination of each lamp in the tunnel reasonably so that it can not only meet the illuminance requirement of tunnel lighting,but also make tunnel lighting system more energy-efficient.In view of the above contradictions and the current situation of highway tunnel operation in China,this paper applies the optimal illumination distribution scheme,that is,under the premise of ensuring the safe operation of the tunnel,the illumination of each point in the tunnel can reach the original set value.It can also minimize the total energy consumption of lighting system,and the illumination distribution of each lamp is the optimal illumination distribution.With the present situation of the research on optimal illumination distribution of tunnel lighting in China,this paper proposes to introduce genetic algorithm into the optimization process of tunnel lighting,and applies the concept of system engineering to analyze and study the more economical operation mode of tunnel lighting.The genetic algorithm based on artificial intelligence has established a general framework for solving complex system optimization problems,and has strong robustness to various problems.On the premise of meeting the requirement of tunnel lighting,through the establishment of tunnel lighting model and the solution of the optimized model,the comprehensive analysis and comparison of the system,the simulation is carried out with the tunnel example,the optimal operation parameters are obtained by the global search,and finally the actual value is compared with the actual value.The result shows that the illumination distribution scheme can not only meet the illuminance requirement of the safe operation of tunnel lighting,but also makes the overall illumination distribution reach the optimal state,which not only ensures the lowest energy consumption of the system,but also meets the lighting standard of the tunnel safety operation.Based on the research and study on the development of energy-saving lighting technology of highway tunnel at home and abroad,this paper puts forward the optimalillumination distribution scheme,combines the advantages of artificial intelligence algorithm in solving nonlinear problems,and cites the genetic algorithm to the illumination optimization problem of the tunnel,and the optimal illumination distribution parameters are obtained by modeling to minimize the error between the actual illumination and the set value in each region.This technology is the key to eliminate the crisscross of the lightness and darkness of the tunnel.It not only makes the lighting brightness more conforms to the driver's adaptation curve to the tunnel,but also makes the driving safer.At the same time,the energy consumption of tunnel lighting is reduced to some extent,and provides a new idea for the design,construction and management of the tunnel lighting system.
