Problems solved by technology

Generally, there are seven or eight lighting control loops in tunnels. The construction investment is large and the construction is difficult. After the tunnel is opened, the manager can only choose among the limited loops, and the dimming control of the tunnel lights cannot be realized, which makes the zebra crossing in the tunnel serious. The uniformity of brightness is poor, and it is difficult to balance the unity of operating costs and tunnel safety
There are hundreds of lights in a tunnel, so expressway tunnel lighting is a big energy consumer

Abstract

The invention provides an intelligent illumination controller applied to highway tunnels. The illumination controller can acquire the traffic flow information of a vehicle detector and the brightness information of inside / outside tunnel environments detected by an outside-tunnel luminance meter and an inside-tunnel luminance meter. The illumination controller can drive LED tunnel lamps to be turned on and adjust the light of the LED tunnel lamps. The illumination controller has a CAN-BUS bus communication interface, can form a complete field bus control network in a tunnel, is connected with a management workstation of a tunnel management office through the Ethernet, and can automatically adjust the brightness of tunnel-illuminating lamp from 0 to 100 percent under the management of the workstation according to the magnitude of traffic flow and the contrast degree of the brightness of the inside / outside tunnel environments.

Description

technical field [0001] The invention relates to an intelligent controller applied to highway tunnel lighting. The lighting controller can collect traffic flow information of vehicle detectors and 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. It can drive LED tunnel lights to light up and dim them. 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 management workstation of the tunnel management station through Ethernet , under the management of the workstation, the brightness of the tunnel lighting can be automatically adjusted from 0-100% according to the size of the traffic flow and the contrast between the brightness of the environment inside and outside the tunnel. Background technique ...
