Abstract

The invention discloses a vehicle information statistics-based intelligent control method and system for tunnel lighting. The method comprises the following control steps of counting basic information and traffic flow information of vehicles which pass through a tunnel within representative 12 days in every quarter and determining period partition reference time according to the time spent by the vehicle with the minimum speed for passing in and out of the tunnel; defining a period through a comparison result of a time interval at which the adjacent vehicles enter the tunnel and the period partition reference time; and then making different intelligent control schemes for tunnel lighting during the day and at night separately. A segmentation node of day and night is found out according to the statistical result of the tunnel vehicle information, and different control schemes are adopted for a lighting system in the tunnel in two periods, so that the stability of the lighting system is ensured and the service life of the lighting system of the tunnel is prolonged on the basis of reducing energy consumption.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting system control, in particular to an intelligent control method and system for tunnel lighting based on vehicle information statistics. Background technique [0002] The road tunnel lighting control methods mainly include manual control, sequential control and automatic control. [0003] Manual control is performed by the tunnel monitoring personnel to selectively manually turn on and off the lighting circuit according to the specific operating conditions and weather conditions of the tunnel. This control method is single, the process is cumbersome, and a lot of human resources are wasted. Moreover, the tunnel lighting control scheme cannot automatically match the current traffic conditions and weather conditions, which is prone to safety hazards. [0004] Sequential control is a control method to change the operating state of the lighting circuit according to different seasons and differe...
