Abstract

The invention provides an intelligent illumination control system applied to highway tunnels. By utilizing an independently developed illumination controller with a CAN-BUS bus communication interface, all illuminating lamps in a tunnel, a vehicle detector, an inside/outside-tunnel brightness meter and a luminance meter are connected to be a complete control network, and the brightness of tunnel-illuminating lamps can be adjusted from 0 to 100 percent according to the magnitude of traffic flow, the brightness of inside/outside tunnel environments and the contrast degree thereof.

Description

technical field [0001] The invention relates to an intelligent control system applied to highway tunnel lighting. The lighting control system controls the tunnel lighting lamp according to the size of traffic flow, the brightness of the environment inside and outside the tunnel and its contrast degree to the tunnel lighting lamp through a networked intelligent controller. Brightness is automatically adjusted from 0-100%. The intelligent control system can collect the traffic flow information of the vehicle detector and the brightness information of the environment inside and outside the cave detected by the luminance meter outside the cave and the illuminance meter inside the cave, and can drive the LED tunnel lights to light up and adjust the light. The lighting controller has a CAN-BUS (CAN, Controller Area Network, controller local area network) bus communication interface, which can form a complete field bus control network in the tunnel, and is connected with the manageme...
