Expressway tunnel intelligent dimming method and system based on multiple parameters

Abstract

The invention discloses an expressway tunnel intelligent dimming method and system based on multiple parameters. The expressway tunnel intelligent dimming system comprises an illumination intensity detecting unit, a vehicle flow detecting unit, an intelligent dimming control unit, tunnel LED (light emitting diode) lamps, a monitoring center computer and a tunnel monitoring system. The technical scheme provided by the invention has the advantages that the lamps are intelligently controlled through the parameters such as tunnel out-of-hole brightness, in-hole inlet section brightness, middle section brightness, vehicle flow, the condition whether the vehicles come or not and the like, so that the black hole effect is eliminated; the automatic management level of an expressway tunnel illuminating system is improved, so that the illuminating intensity in the tunnel can completely meet the standard requirements; on the premise of improving the running safety, the electric energy is saved to the greatest degree. A monitoring center computer and a tunnel monitoring system are interacted; events are divided into different groups such as jam, pedestrians and fire hazards according to the preset made scheme, and are used as one part of the scheme of the whole tunnel monitoring system to perform real-time control on the tunnel illumination system.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting, in particular to a multi-parameter-based intelligent dimming method and system for expressway tunnels. Background technique [0002] During the operation of the tunnel, the maintenance cost and power consumption of the tunnel are very high, among which the lighting system accounts for the vast majority of the mechanical and electrical power consumption of the tunnel. In addition, the contradiction between lighting energy saving and safe operation of the tunnel is becoming more and more prominent. Through advanced technology and management means, the traditional tunnel lighting method can be changed, and the purpose of on-demand lighting can be realized under the condition of ensuring driving safety, which can save a lot of energy consumption and reduce the operating cost of the expressway. The management part is very attractive. [0003] The traditional lighting methods of tunnels have t...

Problems solved by technology

[0005] 2. The lighting system is controlled according to the gradation of brightness outside the cave. Due to the low level of grading control, it takes a long time to adjust the brightness, and the brightness jump is obvious. "blindsight effect"

[0006] 3. The lighting control system does not consider the driving situation without vehicles, and there is a waste of "excessive lighting"
