The Study Of Tunnel Light Environment Artificial Lighting Control And Energy Saving

With the rapid development of highways, road tunnels has become an important part of the highway network, the tunnel as a special section of highway, its lighting is extremely important to provide a comfortable visual feeling for drivers and ensure the traffic safety. While tunnel lighting costs is one of the largest of operating expenses, the current tunnel lighting control system has been unable to meet energy reduction needs. How to optimize the tunnel lighting control and reduce lighting energy is critical to improve traffic safty and energy saving.Therefore, studying the development method of energy saving and optimization of the lighting control system has important theoretical and practical significance.To study the control and energy reduction method based on the particularity of tunnel and the main factor influenced on the tunnel lighting quality. This article is mainly divided into some aspects as follows.(1)According to the visual characteristics of the tunnel lighting, and analysis the main factors of the tunnel lighting quality. Refer to the road tunnel lighting energy reduction, proposing energy strategy from the choice of lighting, optimal design of lighting, lighting control method and so on.(2)By studying a selection of LED light and stepless dimming control mode, analyzing of LED light source characteristics Rising a technology based on DeviceNet is used to design the adjustable light control system and able to achieve the brightness of LED. It's described the system structure and taken the fuzzy control algorithm into simulate.(3)Designing the tunnel lighting control system and building two buses protocol based on Devicenet network. The road tunnel lighting control system is for real-time monitoring through host computer system to achieve the tunnel lighting intelligent control and energy reduction.
