Design of intelligent lighting energy saving system for Expressway Tunnel Based on Internet of things

The power consumption of expressway tunnel lighting accounts for the vast majority of expressway operation cost. In actual operation, there is excessive lighting in the tunnel. In this paper, the expressway tunnel monitoring system designed, network layer and application layer. Through real-time perception of the environmental information and equipment information in the tunnel, the equipment in the tunnel can be intelligently controlled. This paper studies the method to solve the tunnel over lighting, and designs an intelligent energy-saving system. Collect the light intensity of the tunnel and outside the tunnel in real time, and use the connection technology based on fuzzy control idea to control the light intensity in the tunnel in real time, so as to achieve the control effect of "large traffic volume and more time", turning on less lights when the traffic flow is low" and "turning on more lights when the light intensity outside the tunnel is strong, and turning on less lights when the light intensity outside the tunnel is weak", so as to avoid excessive lighting, Realize energy saving and ensure driving safety.
