Expressway tunnel entrance section LED lighting intelligent regulation and control device

Abstract

The invention discloses an expressway tunnel entrance section LED lighting intelligent regulation and control device which comprises an intelligent regulation and control device body, a device shell is arranged on the intelligent regulation and control device body, and a light collector connecting port, an infrared sensor connecting port and an ultrasonic velometer interface are arranged on a sensor mounting plate on the true side face of the device shell. A plurality of LED lamp mechanisms are evenly arranged at the bottom of the inner side of the intelligent regulation and control device, LED lamp beads are arranged in the LED lamp mechanisms, the LED lamp mechanisms can be driven by a double-head motor to rotate by 180 degrees in the vertical direction, the irradiation angle of the LEDlamp mechanisms is adjusted, and therefore corresponding illumination is provided for passing vehicles, and meanwhile dazzling caused by too strong light is avoided. The device can accurately regulateand control the LED illumination of the entrance section of the expressway according to the information such as the tunnel structure, the LED lamp arrangement, the road surface reflection coefficient, the ambient brightness outside the tunnel, the traffic flow and the speed, so that a vehicle driver can smoothly transit to the light environment inside the tunnel from the natural light illumination outside the tunnel, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent and precise control of LED lighting at the entrance section of expressway tunnels, in particular to an intelligent control device for LED lighting at the entrance section of expressway tunnels. Background technique [0002] With the rapid development of my country's transportation industry, more and more expressways have appeared in mountainous and hilly areas, especially in the west of my country, which has also prompted a large number of expressway tunnels to be built and used. In order to ensure driving safety, appropriate lighting needs to be provided at the entrance of the tunnel, but most of the current tunnel lighting control still adopts manual control or simple sequential control, which will inevitably lead to the following two problems: first, the lighting effect is not ideal, and the tunnel The intensity of light inside and outside is not obviously excessive, and cannot be adjusted ...

Problems solved by technology

In order to ensure driving safety, appropriate lighting needs to be provided at the entrance of the tunnel, but most of the current tunnel lighting control still adopts manual control or simple sequential control, which will inevitably lead to the following two problems: first, the lighting effect is not ideal, and the tunnel The intensity of light inside and outside is not obviously excessive, and cannot be adjusted according to the reflection coefficient of the road surface and the tunnel structure, which has buried serious safety hazards and led to frequent accidents at the entrance of the tunnel; secondly, it has brought serious waste of power and human resources, which has Data show that tunnel lighting has become one of the major pressures faced by expressway operations
