Problems solved by technology

The current tunnel is based on the year-round driving safety requirements. The design of the maximum illuminance in the tunnel is based on the maximum brightness outside the tunnel, the maximum traffic volume and the maximum speed of the lamps in each section of the tunnel. To deal with different weather environments, there is a huge waste of lighting

Abstract

The invention discloses an LED control system used for tunnel illumination, and relates to the technical field of tunnel illumination. The LED control system comprises an information collection unit used for collecting environmental data, an information analysis and processing unit used for analyzing and processing data, a control unit used for controlling the LED illumination luminance, an LED illumination unit used for providing a light source for a tunnel, a feedback unit used for feeding back the illumination parameter and circuit fault, and a monitoring unit used for a manual management control system. By collecting the atmospheric visibility and illumination luminance outside the tunnel, and vehicle speed data, the lamplight illumination intensity in the tunnel can be adjusted in real time, a ''black hole'' effect generated in the tunnel when a driver enters the tunnel and a ''white hole'' effect when the driver drives out of the tunnel can be eliminated; when there is no vehicledriving, the illumination in the tunnel is lowered to the minimum, so that waste of illumination is reduced, and utilization rate of resource is improved; by virtue of the feedback unit, the illumination parameters and the preset input parameters can be compared, so that system illumination error can be lowered; and by virtue of setting of the monitoring unit, system examination and maintenance by a maintenance staff can be performed conveniently.

Description

technical field [0001] The invention belongs to the field of tunnel lighting and control systems, in particular to an LED control system for tunnel lighting. Background technique [0002] When the driver enters the tunnel from a bright exterior to a dark interior, the vision will have a certain adaptation time before he can see the situation inside the tunnel clearly. This phenomenon is called "hysteresis of adaptation". If the tunnel is long enough , what the driver sees is a black hole, this phenomenon is called "black hole" phenomenon. According to the "Design Code for Ventilation and Lighting of Highway Tunnels", conventional tunnel lighting is mainly divided into four parts: entrance section lighting, transition section lighting, middle section lighting and exit section lighting. The current tunnel is based on the year-round driving safety requirements. The design of the maximum illuminance in the tunnel is based on the maximum brightness outside the tunnel, the maximu...
